Mine is around 9:1. I have run up to 30lb of boost on mine. I've heard rumors of guys running more compression. I would imagine you could run more compression, less boost, a little less timing than a 9:1 motor and it would work. :smt102
The SCR is quite misleading from what I have seen.
There's also MANY MANY more variables to look at than just SCR vs. PSIG.
Remember PSIG (gauge pressure) is just a measurement of restriction, so 23 PSIG on a SBC will not be the same flow (CFM) as 23 PSIG on a SBF, or even another SBC for that matter. Cam(s), porting, intake design, even the headers can effect PSIG.
I use PSIG to compare changes on the same vehicle, mostly.
Has anyone seen any improvements in performance by raising their fuel pressure? I'll be installing one of the new Aeromotive pump in the next week and it has enough pressure/volume capability for me to easily raise the base fuel pressure from 45 to 65-70. I don't figure going higher is a good...
They did the classic bait and switch......kinda. Everyone thought the big news was the new full color digital dash. Well Thursday morning I get a Dealer Tech Bulletin about a new controller. It didn't give a lot of details but I made a bee line for the Haltech booth
WOW!!! They have not released...
