Default Anyone have their timing logged & amount of Psi?
Interested in what data others have with the mods they have if they could be listed. The basic data and what I should see. My mods are listed but I only logged psi once and got 20.6psi. I expect it would produce 21-22psi with good intake air.
Timing is what I would like to see if anything. I have the 70mm SC pulley and a 178 crank pulley.
Today I found one of the 2 small vacuum/boost rubber lines that are located by the drivers side/rear on the SC having but a thread holding it there so I took care of that. So here are the stats I have:
1. Boost: call it what I have seen, 20.6psi
2. I have to check the timing again under WOT boost condition and this is what I would like to know what you have.
3. I am running 550cc injectors, a 450cc tune for running TORCO+1.5* of timing. The TORCO was run at the full amount of octane it could possibly achieve. Since the timing is a bit high I run an AFR I believe is rich enough to prevent harm. 11.6 is about as lean as the motor sees. I remember Jim(quickest Crossfire V8 at 12.2 but his is pretty much a race car. I am primarily interested in torque since much of the driving is part throttle, interstate passing, quick response conditions. So I compensate by running a richer AFR than some. 11.2-11.7 is my target range. My timing is what I will log once I find a safe spot to run hard in 3rd gear. I am thinking the most timing the motor should see would be 22*?
Mods being considered are exhaust work: A Magnaflow TRU internal x-pipe to replace the rear cats, a Magnaflow "Y" to follow the Muffler, resonator delete with a Borla Pro XS for the rear muffler. Borla's DO NOT DRONE I have to get a good looking set of tip(s) for the Borla. I may even add a round;internally baffled(perforated) muffler if there is space. maximum power done quietly.
I'll do a run with the Euro datalog software and list the timing in 3rd gear from shift into and shift to fourth & log here within a few days. Thanks all, sweet
