So I'm throwing a CX Racing air to air intercooler on my setup. Currently, in short my setup is:
- Non-intercooled Novi 1200 with 3.33 pulley (kisses 13 PSI at 6300-6400 RPM before shifting)
- Cheap meth injection kit spraying at over 4 PSI
- 21* of max WOT ignition timing, 11.4-11.5 AFR
My IATs are making it into the 150*-ish range at the very end of a 1/4 mile pass. I'm guessing the car is putting down ~480 RWHP with a typical peaky centri blower curve. It's trapped 120 in the 1/4 mile a few times at full weight, and usually traps in the 116-118 range.
I'm hoping the IC, in combination with the meth, really drops my IATs. I'm contemplating three routes of action:
1. Leave everything else as is and hope for some power gains due to the colder charge.
2. Add a few * of ignition timing at WOT.
3. Drop a 3.25 pulley on the car.
Recommendations?
I'm thinking I"ll be pushing it with more then 21* of timing - I'd have to think cylinder pressure would start getting too high and I'd be in headgasket-danger-land.
I'm also a bit afraid to throw a smaller pulley on it, for the obvious reasons.
What do you guys think? Leave it alone and see how it does?
