Thinking I'm going to boost
Current setup is 383, HSR, forged internals, flat top (-5cc) pistons, AFR 195's shaved to 60CC. All supporting mods already done. I do my own tuning. Car runs 10.55 @ 133 on a 200 shot, 12.08 @ 114 on motor. 3520 lb raceweight. Will be faster with a harder launch now that I have a D44.
Thinking of changing heads to AFR 195 streets with 75cc chambers. With my deck height and head gasket choice I'll be at 9.67:1 Static compression. Cam is a flat tappet 230/236, 110 LSA, 1.7 rockers. I'd like to not change the cam.
My question is, with the 9.67:1 compression, how much boost can be run without, and with, meth injection. I'm thinking of a Vortech T-trim or, if I can swing it, a YSI. I was thinking of maybe 15 or 16 lbs if possible.
My goal is to run the same mid 10's when at the track, maybe even low 10's, but have the power always there instead of out of the bottle. I don't want to slow down any, but I'm also not looking to be much faster.
So, what do you guys think? How much boost will I need to meet my goal? How much can I run with 9.67 SCR? I have a Crane Hi-6CD ignition with a retard box so controlling timing won't be a problem, and I have a Walbro 255HP with a KB boost-a-pump and will change injectors to 60's or 80's so fuel won't be a problem either.
