When I sell my stock seats, turbo, and my brand new coiloves I think I might pull the trigger on the S2's. Then Mellon and I can play ECU maps some more. :P My car wants more power it doesn't give a **** that the fenders rub my tires when I turn so the coilovers got's ta go!

I hope you were going bigger turbo. The 4" intercooler and the S2's for sure are hurting spool. Let's see some stock logs compared to now. When are you spooling? Not to sound like a dick either but the numbers are a little low. I have seen S1's do the same thing.

Reminder, I am on the small 9.8 hotside.

I will get an updated dll graph sometime this week.

We have changed the tune up some since I plotted that graph.

Also read my post where I stated that I was going to a HTA35r kit all along so this wasn't just a test of if they would make x more power over some other cams.

I want to only buy parts once.

Brad,

What RPM is idle at on your S2s? it sounds pretty smooth for it being on the stock ecu, good job!

Brad, I just listened to your S2 clip and it sounds a little rougher than Lucas' but then again I think the 10:1 is making up the difference. Sounds PERFECT to me though

Do you have a sound clip of Lucas's?

Aby gained considerable power with the Cosworth M2's over the GSC S1's on 91 water/gas. Just something to think about. He has not tried the S2's yet.

Don't know how I missed your post but if you are not going to rev out past 7200 then I would not suggest these cams.

Although I agree with your opinion and have nothing against you, Since there was no direct comparison we cannot conclude what the difference in performance would be with the S1 Vs. S2. The S2's against stock are def. a big improvement.
