View Full Version : oscar jackson releases new SC for S2k

this thing is pretty sick. up till a few months ago, only SC was comptech and vortech. both are centrifugal and pretty much only increased power above vtec. both belt driven. oscar jackson started new company Kraftwerksusa. he uses the rotrex SC which is belt driven but uses some goofy fluid to transfer energy instead of a shaft and gears. its more efficient and actually allows the SC to build boost faster then a comtech or vortech.

check out his site.

www.kraftwerksusa.com

this is 9psi kit on 2006-08 s2k.

pretty impressive. now of course with the turbo kit you can make 550 whp max and the kw kit you can do i think around 425 but hey, its damned impressive for what it does at 10 psi.

I'm still not a fan of boost by rpm, their "10psi kit" doesn't hit 7.5psi until 7000rpm. a turbo kit at 10psi and you would hit 10psi from at least 4000rpm on with the right size turbo. so maybe the peak power would be the same but the midrange would be a huge difference, power under the curve playa!

I also never trust those cropped dyno's, I'm not saying that it can't make that power, just that who knows how they're manipulating the dyno, remember the church guy's dyno's :) they're also using a superflow dyno, I wonder how their superflow dyno compares to a dynojet as far as numbers?

but with your rediculously short gearing once you got into the charger's powerband it would pull pretty good.

Yeah but Honestly, the boost by rpm I bet inturn gives for a smooth daily driver. You don't have to worry about full boost under slight accelleration which is going to be kinda annoying for a DD. Just a little perk i've learned with my car.

My srt was nice because of the ebc. Have a nice low low setting :)

Yea that boost by RPM drives me batty.

Turbo cars are smooth daily drivers as well, just takes some getting used to and a little playing with the throttle input. At first it's a little wierd but you get more used to it the more you drive. If you let out a bit when you get the surge you get the gain of the boost without it giving you the big jolt ramping upto full boost. Just have to be smooth with the throttle.

Honestly, I like the roots type blower like Rich has. Yea they don't make huge power but they make decent power and good power with the intercooler and off idle boost is pretty wicked.

Now if Kenne Bell made an S2000 kit I would buy another S2k tomorrow and place the order for the kit same day :D

thats why i posted the last dyno which is dynojet ;)

the inline pro dyno i posted is representitive of a 10psi kit bolt on for an S. ust look at the hp at each rpm. crazy how more efficient it is. i cant wait to see what people how bought them produce at the track and what the KW kit will do at 15psi.

can't see the turbo dyno, work is blocking that site :(

that last one isn't dynojet software, you can't make the software display the graph that way, play with our dyno's and you'll see what I mean. not that big a deal I guess but it's always shady when you can't see the whole dyno sheet, don't know the correction, can't even see what shop it is, etc.

either way the boost by rpm is ghey, it's the same reasons why we talked Gavin out of getting the vortech kit for his mustang, don't do it! :D

all I'm saying is that a dynojet dyno graph doesn't display the graphs that way, the software won't let you do it, at least not what we downloaded from dynojet. the dynojet graphs don't display the rpms that way and don't have the arrows to the peak power point like that, and don't draw the lines bold. so that makes me think it's not a dyno run from a dynojet dyno, I didn't say he lied about the power, just that it doesn't look like a run from a dynojet that's the standard and easier to compare to other dyno's.

I wish your inline pro dyno was an ap2 and not an ap1, can't really compare the two easily.

yeah my posts have been negative, I would never get a boost by rpm style form of forced induction. I just think it's dumb to get a kit that only gives you full boost at redline, at least with the turbo half your powerband is full boost. so yeah with the KW you have 364whp at redline when you shift, then you land on 6500 rpm to start the next gear and you have 290whp, you're down 25% of your peak power starting the next gear. the turbo dyno you're only down 11% from peak to start the next gear, more power under the cuve nucca!

here, this takes the dyno Al posted and overlays it with the KW dyno. lets assume the peak power is the same from the 10psit turbo kit and the 10 psi KW kit. if you line the peak power point up on both with the turbo kit you have more power with the KW until about 3500rpm but then the turbo gives you more hp from 4500rpm until 7500rpm and more trq from 4500rpm to 6700rpm. on the street you load up the turbo even more so you would boost down low a little quicker and have more mid power. with a smaller turbo like a GT30 then I bet it would spool up closer to the 3500rpm mark and still give the same top end power. kinda hard to see but look at the dotted line for the 10psi turbo power...

http://www.superpimps.com/candymanjl/crazydyno.jpg

if kenne bell would sack it up that would be sick, I would maybe pick that over a turbo kit, never gonna happen though :( they're ghey for not going after the import market more aggressively, people are obviously spending the money. at one point when I talked to them they said they were working on a kit for the older B-series Si's, never saw anything about it though.

only problem with the dyno Al posted is that it's on a racepak, I'll bet its in that ghey mode where it's trying to calculate flywheel hp like everyone likes to do. the picture is cropped so you can't see the part of the screen that says what mode it's in. either way from 3500rpm on it's more area under the curve. I wonder if the KW kit in in "flywheel power" mode hummm :D :p

edit: I played with the superflow software and it doesn't look like it's got the ghey flywheel power mode.

that's pretty baller then! too many times we've noticed racepak dyno graphs set to "fhywheel HP" so they're adding power to try and simulate the power at the flywheel. annoying when you're trying to compare dyno's.

if that's wheel hp then the dynos look like this...
http://www.superpimps.com/candymanjl/crazydyno2.jpg

I still believe that the turbo dyno at the same psi should be higher since it's not belt driven. since the racepak measures power differently than the dynojet it's still hard to compare.

Yea, dyno sheet is from Jeff Evans...he doesn't care much for flywheel hp cause that's not what his customers want and he isn't trying to sell anything. He is just tuning what they bring in for him so he's got nothing to hide.

Almighty-Si
06-08-2008, 12:39 AM
Regardless of the different machines, the turbo will always out perform a boost by RPM set-up at the same boost level.

Sure you may get some boost pressure down low to give you some more whp and tq there but we drive Honda's with 8k revbands, hell the only time we're under 3k is when we're coming to a stop.

Honestly, you are just about half way there. You want to save a ton of money, buy the head flange, turbine flange, exhaust flange and pipe. Take a weekend get the header off and measure cut everything out for the manifold/downpipe and tack it together. Then put the header back on and drive the car, take the tacked pieces to a person who tigs and let him finish it off.

It will probably cost you $100 in parts for the manifold and $150-300 to have the guy weld the rest of it up for you. Let's say worst case senario you pay the $400 that's still $200 cheaper than the cheapest manifold I have seen for that car. After that it's just about getting the rest of the parts needed for the car basically. You may have to fab up some charge pipe but that's not all that big of deal.

If you're not looking for a ton of power and want something that will come on quick there is always the GT2871. It should come on before or at 3k rpm hold the power to redline and is good for 440whp.

good news. first i owe rich and apology cuase it is not a dynojet, but a dynomite dyno. you can read about them on http://www.land-and-sea.com/chassis-dyno/chassis-dyno.htm

the good news is they dyno within a few hp of a dynojet, so they 377 dyno is still pretty representitive of what it can do on 10psi. the first dyno showing 364 was done on 91 octane in california.

still its not a dynojet its a dynomite. i swear i wish they would just standardize dynos so you can compare them all. it still makes me laugh that all dynojet dynos use a calculation based of a 1985 yamaha motorcycle. rofl, its called a fudge factor that the owner admits he used to make the dyno read right.

I would buy a manifold but S2k manifolds are pretty rare. The ones you can find are usually the log cast iron ones and are going upward of $650 and then there is Full Race and we all know how cheap those are ;)

This way you can have a nice shorty tubular manifold and still save $200-300 bucks to be spent elsewhere.

I guess I should rephrase, welding is easy, but welding to where you don't have to hide your welds is not east at all :D I would just cheat, weld everything up then come back and grind everything smooth :)

I hear that ! I have gotten better though. I have gotten to a point where my welds don't look like "bird shit" but I still get some of the splatter I have to clean up with a grinder. I think that if I actually took the time to prep the metal before welding it would help a lot :D

I don't do bad though for using a $200 Craftsman with 2 damn heat settings and fluxcore wire...LoL

candymanjl
06-08-2008, 12:17 PM
ha ha, I've got a lincoln electric MIG welder. I need to get the gas so I can stop using the flux core wire, that stuff is so messy. prepping does make things easier, when it's nice and clean that really helps. I would love to get a TIG welder, being able to apply the heat seperately from adding the wire would make it a lot easier to get clean welds.

Almighty-Si
06-08-2008, 12:34 PM
Yea was toying with the idea of a TIG but I don't do enough welding to justify the cost. I look around occasionally for a used TIG setup and if I ever come across one cheap enough I will pick it up but they are usually in upwards of $1500.

06-08-2008, 01:43 PM
the lincoln electric one I was looking at is $1,300, little too much for the amount of welding I do, but it would be cool :) a plasma cutter would be rad too :D played with one of those at anthony's job, cuts metal like a hot knife through butter!

No way to talk you out of it huh? LoL Its cool. I'm not knocking it, it's a sweet powerband and 370whp is nothing to sneeze at I just wish they could build a system like that, that can actually make full boost before you get to max rev. Then again it makes sense why it can't cause of the way it works.

Anyways, I wouldn't turn down the ride if you threw me the keys :D

Is Jackson working on or have anything for the S?

candymanjl
06-11-2008, 01:09 PM
Oscar Jackson's new company is "Kraftwerks" so this is his S2000 kit. I honestly think the only reason he's using this charger over a Eaton style kit is that he probably has a non-compete clause with Moss Motors who bought the Jackson Racing product line. yeah the eaton would make less peak power but the powerband would be HUGE. the boost by rpm style kits put down great peak numbers but it's gay until you get to redline. same reason we talked gavin out of the vortech kit and into the kenne bell!

I want to see someone dyno the kit not on Jackson's dyno. see some joe shmo real world results where it's done on a dynojet and you don't have to worry as much about someone manipulating the numbers. if it still puts down the same power I'd be shocked. if you really want boost by rpm that badly we'll program the AEM to do that with the turbo! :D

I say we buy a Kenne Bell supercharger by itself and make a kit :D

Camuman

The whine from the SOT kit gets me all happy in the pants ! :D They don't give much info of the kit on the site though....wonder if it comes intercooled or not? With a 10psi pulley I can't see being too far off what the KW kit is making. It may be a little less but i'm sure you will see greater gains down low.

If you ask me and turbo is definitely out of the question, between what you have posted I would go with the SOT kit hands down. Again, just expressing my thoughts :D

candymanjl
06-11-2008, 08:58 PM
the eaton will give you a huge power boost down low and through the mid range. at the last little bit it'll start to fall off but after each shift you'll go back into full boost instantly so the acceleration won't be hurt too bad from the loss of power. that kit has been under developement so long who knows when it'll be publicly available :(

Almighty-Si
06-11-2008, 09:31 PM
It's available, atleast that's what their site says. 2 verisons of the kit, one with engine management other just the kit itself. Price of the kit itself <drum roll>


$5,195.00 !

I could build a mean ass turbo kit for that kind of money :D

Camuman
06-12-2008, 10:30 AM
yeah kit is intercooled and if you look at the dyno power clims to redline. the max boost they want to push on that charger i think is 10, there hoping 370ish is doable. only annoying part of this kit is the ac lines have to be rerouted :(

Almighty-Si
06-12-2008, 01:59 PM
Yea redoing a/c lines is a pain but I think it would be worth it. It sounds bad ass but most important the powerband is going to be better. With the intercooler I also think you might able to squeeze another 2-3psi out of it. Getting it spin up that high might be a challenge if they don't make a pulley for it but if you wanna be a balla you can send me some specs and I can take them to unorthodox here in NY and they will make some for ya :D

candymanjl
06-12-2008, 03:56 PM

no doubt! I agree, at the very least get the thicker headgasket that drops the compression to like 8.5-9:1. lots of guys have had 400-500whp S2000's for a while now just by doing that.

WOW that's a thick ass gasket. I don't know if I would go that far but yea it's a bit of a safety net. If he's not looking to go into the 400's I wouldn't even bother with the headgasket. Just don't be too generous with the timing.

Camuman
06-14-2008, 02:02 PM
i have been really annoyed that each dyno reads so differently. i read some posts about them all, and pretty much the only thing you can gaurantee is that pick a dyno and stick with it. dynodynamics and mustang dynos are better to tune on, dynojet has a loading feature but not as good as the other two, and even worse for AWD cars as dynojet only loads one of the rollers and makes your cars diff do the work for the others :(

power wise, omg there all over the place. the bad ass sot supercharger was dynoed on a dynodynamics dyno. its called the heartbreak dyno due to considerably lower numbers then dyno jet. ugh, one post i read the guy did 275ish at dynojet, then drove to dyno dynamics and made 255whp. makes me wonder what this kit is on dynojet or what the KW is on a dynodynamics.

http://i241.photobucket.com/albums/ff219/mugenrios2k/SOTAP2330whp.jpg


this dyno with 8% more power would be dirty!


the owner of this kit recently moved vtec lower and will redyno to see if there are gains. kit comes tuned with vtec left alone.

Almighty-Si
06-14-2008, 06:34 PM
Yea it is kind of a pain in the ass but you can always take the numbers and factor in the % for dyno correction.

8% on 330 = 356 and it doesn't only fall at peak it will be up and down the powerband. Then you have to remember you have another 3psi to go :D

On a dynojet I don't see this kit being far off 400whp

candymanjl
06-14-2008, 08:20 PM
lol, you lose a 100whp when you shift from 8000 and land at 6000. yeah you can move VTEC lower but then cruising on the highway you'll be into VTEC a lower speed, that's why you didn't already lower it for your all motor setup. unless you set up the AEM to kick in VTEC based on boost.

the dynojets calculate AWD power the same exact way they calculate power for FWD and RWD. on their AWD setup you spin two seperate rollers and the software just adds the two power numbers together. your right unless you add the eddy current option you can't load the dynojets as much as the other dyno's, who knows which one is "right" or "more accurate". they're all different so for me as long as they're repeatable and consistant then that's the most important part for tuning. if I had a shop I would buy a dynojet just because that's more of the industry standard and is easier to compare to other people's results.

if this dyno is like a mustang dyno then add 5% to make it line up with a dynojet and you're at 345whp, 4whp under the 2.0L AP1 turbo kit dyno you posted. this makes more sense, the belt driven, boost by rpm system making about the same peak power just less power under the curve everywhere else. find any dynojet dynos? just wondering how different they are compared to this dyno.

the dynojets calculate AWD power the same exact way they calculate power for FWD and RWD. on their AWD setup you spin two seperate rollers and the software just adds the two power numbers together. your right unless you add the eddy current option you can't load the dynojets as much as the other dyno's, who knows which one is "right" or "more accurate". they're all different so for me as long as they're repeatable and consistant then that's the most important part for tuning. if I had a shop I would buy a dynojet just because that's more of the industry standard and is easier to compare to other people's results.

if this dyno is like a mustang dyno then add 5% to make it line up with a dynojet and you're at 345whp, 4whp under the 2.0L AP1 turbo kit dyno you posted. this makes more sense, the belt driven, boost by rpm system making about the same peak power just less power under the curve everywhere else. find any dynojet dynos? just wondering how different they are compared to this dyno.

little lost here.

whats wrong with losing 100hp on the shift, the ap1 turbo dyno i posted loses about 100 on the shift too. shift at 9, land around 6ish. gearing was different in those cars.



the eaton dyno i posted has stock vtec engagement. 6k. he is lowering it to 4ish and making it load based. might add more midrange.

we did lower my vtec from 6 to 4900. stock ap2 is 6.

he will redyno and see how it looks.

my bleh to dynojet was there awd dyno with eddy current option doesnt load both drums during tuning. it loads one of the them and makes your center diff eat all the force instead of loading the other drum and givng those wheels something to push against. thats all. even though the dynopak is weird the way it dynos, seems pretty consistent that its great for part throttle tuning.


i am curious to see what the dynojet inventor does the second time around in building a dyno. he didnt release his fudge factor info until a few years after he sold the company. maybe he has something up his sleeve to improve upon it.

you're right, it's hard though to compare the 2.0L 9k redline dyno to a 2.0L 8k redline dyno. all motor you're only losing 20% from 8k to 6k, so 350whp at 8k and you should have around 280whp at 6k, 30whp more than the dyno shown that's losing 100whp at 6k. that missing 30whp is from it being boost by rpm, a turbo kit would have the same psi at 6k as it does at 8k with the right wastegate and boost controller.

I remember we changed VTEC, it just seemed like from the post he was going to lower VTEC a lot more than to 5k, 5k would probably work good and smooth things out. load based on the eaton will work great, Jackson Racing sold a Hondata setup for their B series kits that would engage VTEC from 2500rpm up if the boost got over 1psi.

the eddy current thing is optional on the dynojets so if the shop doesn't have the eddy current option on both of the drums on the dynojet AWD setup then it's because the shop didn't spend the money. it is a pretty expensive option but pretty dumb for the shop owner to just put it on one roller in an AWD setup, like you said you're powning the diff.

everyone is playing with the numbers, there's so many variables it's ridiculous. one mag took a car to the dyno, strapped it down, did a pull, didn't change anything to the car, took it completely off the dyno and put it back on and the power changed. all the little differences between the two pulls add up, atmospheric conditions, how tight / loose it got strapped down, tire pressure changes, etc. it wasn't a huge change but it was like 5hp.

it will be interesting to see what he does, it won't be like the dynojets since he'll have a non-compete clause from selling the company I'm sure.
