Some background, my engine is a LS2 402 chevy 10.25CR, TFS 235's, plastic LS6 intake 90mm TB, 240/248 114 cam. Head flow around 340 cfm, poor plastic intake probably only flows around 280 cfm.

Anyway-last year I ran a A2A intercooler-the core size is 28.5"Wx6"Hx3.5"D-the core flows 1900 cfm according to BELL.
It's a vertical flow-3" inlet 3.5"outlet that opens to 4" and goes to TB.



Car made a max of around 18-18.5 psi, made over 900 rwhp and ran a best of [email protected] on pump gas and meth-IAT temps were in the 75-85 degree range-85 degree temps were on 90 degree days. Car weighs aound 3650 with me in it.

This was with a YSi with a 2.75 blower and a 8" crank, shift point was 66-6700 for a blower rpm of around 67k running a 10 rib.

After doing alot of reading here it seems that most of you run a A2W or no cooler at all. A2W is not an option for me as far as packaging and that this is a 100% street car. But from what I'm reading-I'm hearing that the A2A could be a restriction?

Now I could go to a 4.5" thick core and that core flows around 2400 cfm-but will it even make a difference?

Is the YSi just too small and I can't spin it any faster unless I go to a bigger carank pulley like a 8.5-that would give me around 71 K. I have an F1R here that is actually on the car right now-I've been told not to spin it any faster than 74K or it will make a tonne of heat-like 300+ degrees outlet temps.

Now what are your thoughts-is my A2A too small and killing boost, should I just yank it and up my meth nozzles to get the IAT's in check? How hot is hot and can I make it live with my 10.25CR motor and C-16 and meth? Should I ditch the YSi and just run the F1R?

TIA.

I run a procharger A2A IC with an IAS system too. Do street driving so the a/a made more sense. Pics in the sig.
