yes, t3 single scroll .82ar. not sure on size of runners, but 1.5" sounds right.

 

aaron, what kind of gains can i expect if i upgrade cams to either s3s or the other spec ones? would the head still be limiting that they won't do much other than move the power curve to the right?

 

Once Keith's car is finished I will have an exact number for you, but based on what we saw with the R2s in Andrews car on a Red (at only 400whp) I would presume 50+whp at 700whp.

 

cool...will the r2's hinder spool up?

 

They didnt in Andrew's car. In fact it looked like they helped.

wow. didn't read this till now. +25whp AND faster spool just by switching to the r2's? nice. might consider a swap down the road.

 

wondering if anybody has switched from gsc s2's to r2's and what the gains were....

 

Awesome!!!

 

s3's, 3.5" exhaust, and new head on the way!

 

Just Andrew and that was 25whp. R2s are a little hard to come by, S3s are really obtainable in comparison.

thanks for the info aaron...

 

This should push your car closer to Keiths which did 762 at 32psi.

 

very nice

 

Nice!

 

Aaron, do you have any hunch what this setup (or similar) would do on some 93 octane? How much spool would be lost? I have a similar combo (2.4/S3s/Ported Head/Ported stock IM/Cast Mani/3586) and am going to have the car primarily on pump and have this exact response as my goal.

Beautiful job here!
