One of my customers has an h22 swapped Del Sol. The motor was bone stock an he competes pretty regularly in all the local track events.

At the last track event, he mishifted an got some valve noise. He decided to take it down over the winter and build the head.

Previous setup:
STOCK H22 LONGBLOCK (stock intake manifold, stock tb, stock cams)
RSR header
2.5in crush bent exhuast

New Setup:
Stock h22 block
Skunk2 PRO1 Camshafts
Skunk2 Valvesprings and Retainers
Skunk2 Flat Faced Valves
RSR header
2.5in crush bent exhaust.

Got a chance to dyno it last night, this was a quick tune, as he didnt have the funds to tune it for along amount of time. But the gains were impresseive to say the least. He is gonna enjoy it, and bring it back in march to see if we can crack 200whp which im sure its more than capable of.

BLUE=OLD SETUP
RED=NEW SETUP WITH SKUNK2 PRO1 CAMSHAFTS


As you can see, the new cams dominate EVERYWHERE in the powerband, as much as 28-30whp in some spots.

We will switch headers im sure by next year. but i thought this was great info for you H22 guys with stock bottom ends.


FYIur dyno is VERY CONSERVATIVE, its very rare to make over 200whp on our dyno. most stock h22s with i/h/e make between 165whp-175whp.

 

crazy gains...is his IAB still hooked up or not?

 

no they are removed

Stock T-Body?


Good numbers through a tail pipe, I bet it would hit 205+ retuned open header.

crome uberdata?

 

Stock TB, Chrome Pro

 

2 words, very impressive!!

 

Maybe I SHOULD build an H next.

...Sicne my pockets aren't deep enough for K's.

 

When he comes back to your shop, please take a close look at the cam lobes and rocker pads. I hope everything looks fine. I'm interested in any abnormal wear with the cams and/or valve springs.

 

Nice. What are the specs on those cams? Wonder if they would perform better than what im running..

a proper valve adjustment was done, ill be sure to inspect the rockers of have him do it every 1500-2000 miles

 

Those numbers are very impressive especially the power under the curve. Did he have an intake?

Is that proven that you would gain that much ? Because on my car it felt like i lost power (butt dyno).

tuned, yes absolutely. Crush bent exhaust isn't going to help anybody

 

Quite a nice improvement. I bet that the customer was pleased.

 

i here that they released the stage three for the H
i might try it

 

Lookin good!! gettin over the 200 mark shouldnt be a problem at all. Sent you a PM Vteckidd

 

So was the baseline dyno done after the motor had bent valves or while it was still healthy?

Was any porting done in the head? What is the c/r with the flat faced valves? Was the head shaved any? Sorry for so many questions but I'm in the market for cams and the Pro1's are on my list of possibilities.

 

 

shouldnt the tq be higher? either way nice dyno numbers...1320 times please! lol

 

baseline was about 2-3 months ago. the motor was healthy then, this is a real world gain, no bullshit.

i couldnt believe it myself, ive never seen cams pick up that much power.

He wanted to port the head, but i decided to spend that money on a new timing belt, water pump , and the auto to manual tensioner conversion for safety head is STOCK as far as porting goes, and i believe the valves are maybe a .2 bump in compression.

Head is not milled, NO CAM GEAR ADJUSTMENTS as he has stock cam gears. Stock Intake Manifold, stock TB.

He is most definetly happy. Before we dynoed it, i was going to be happy with 185whp.

TQ might be a little low due to the header, and the fact taht it has stock timing in it . there is still more power left in it. Open header, with a little more tuning an i bet it breaks 200whp easily.

Skunk2

 

damn...gutt it, put a b16 tranny on it and go rip it on the track.

 

nice, must be fun to drive

 

nice
