Hello all just got my winter project tuned today by Jeff Evans! I have been planning/gathering/saving for parts for nearly 3 years for this setup and its finally complete and I am so happy not only with how the car is running and numbers it made, but Jeff Evans is top notch knows his stuff. A very down to earth guy to deal with and talk to, he answered all my little questions emailing back and forth very quickly and was very informative while the car was being tuned, highly recommended!

Now thats all out of the way here we go!

~~~Final Thoughts~~~
I have desired this style of supercharger since it was first released back in 2008 but as quickly as it came onto the market it was gone after production stopped. I was very lucky and fortunate to purchase this kit 3 years ago as I have not seen another one for sale here on the forum or anywhere else since then.

My goal is/was 400whp on just the sc although as most of us in the know the PD style blower is not something to be chasing peak numbers with its all about the curve. When I was tuned it was 88 degrees out and 85% humidity although the water meth sort of negates the weather, the weather conditions were not the ideal. Jeff had mentioned if this was winter Id be seeing another 10-20whp. And I believe IMO theres room for efficiency improvement on the progressive delivery of the water meth.

This ENTIRE setup was meant to have a 25-50 shot of nitrous pre blower on top of everything I already have which is part of the reason for the 9.5:1 compression. I opted to hold off on the nitrous for now as I want to drive and enjoy my car this summer as I hardly drove the past year because of the oem clutch going out.

Its all about that water meth bro Almost doesn't matter what the ambient temps are, its the great equalizer. Loved that stuff when i was boosted. Congrats, have fun!

Nice knowing there is an integral piece on that motor that came off one of mine too

Evans is a cool guy. Tuned my car. Runs strong

WOW a very cool set up you have mate.

Someone should overlay a 2.4stroker 380whp centrif style Supercharger Dyno over this so see the difference in Torque.

You can tell just by looking at that graph that it has a ton more midrange than a centrifugal. That thing must be a blast to drive, congrats!

Ahh yeah! 200lb trq at less then 2500rpm is nuts. Its not totally apples to apples this being a 2.4, but a 380whp centrifugal F22 puts down roughly 235trq average, so 45lb difference is pretty substantial in blower type and .2 more stroke, but more then that is how broad across the rpm range that trq curve is, which is really the bigger impact.

A typical centrifugal sc with an f22 at 450whp puts down about 280trq.

I was just talking to a kid on a FB group after I posted up my build. He goes "is that it?" meaning hes someone lacking knowledge about dyno curves vs peak hp because hes running a KW kit and hit 430whp. Comparing our 2 dynos at the 5250 crossover I have him beat by 50whp and 55tq. Meaning I have a far more powerful midrange/fatter curve and he beats my whp ONLY the last 1k rpm because centrifugals have the peak power for all them "bragging rights yo"

Which do you think would be faster?

JUSTINTHECOASTIE

This is awesome no doubt, for reference may you provide a general cost list?

s2000Junky

Typical lol

Well you would have the advantage 0-60mph if you could control wheel spin, and your car is going to require less effort to stay in the powerband, which is also an advantage in the long run for being consistent on a road course setting. Its a toss up on freeway pulls to a point, but eventually he will start to pull on you as you start running into aerodynamic forces and trq and weight play less a roll, but id say that wont come into play until you get over 100mph. All around stop light to stop light action and point and shoot out of the canyons, your car should dominate though, assuming both you guys know how to capitalize on the performance of your cars. Driver is always a curve ball.

An easy general way to examine the power curve comparisons between cars is to consider the environment ie road course or drag racing and the speeds/distance etc. And just focus on the rpm range forward that is being used during max acceleration between each gear. So for our car say 6k rpm and up for example, anything before that in a drag race is moot. Then start comparing the rough averages of trq and hp within that rpm range and the weight of the car (same in your case) and you can get a pretty good idea what your up against. Its going to come down to who has more power over time really.

Theres several factors going into this that lowered the cost of this build a good amount and most of you wont experience this. Ill give a short generalized list I dont want to get into to much detail with prices etc.

My BUDGET with everything listed above AND AND AND the cost of the car was $15k, that seems REALLY low right your thinking how the hell did he do that?!? I did go over budget at bit at right at $16k with tuning.

02 S2k rebuilt title 80k ( 92k now ) - $6,500
Sale of original F20c + $2,350
Sale of spare engine I parted out, various other extra parts I had laying around + $2,000

I got a good deal on the stroker used from an ILP employee with 5k miles on it. If I had built it brand new and I DO have all receipts it would be a $9k + bill with the ILP Stage 3 Cams that came with it that I didnt use so that lowered the cost another $1k. Also got a good deal the SC kit. Everything else was used I bought very little brand new but the meth kit, oem engine mounts, clutch, gauges, and random hardware.
