Whats the exhaust temp for your car at how many HP you have??? Just trying to do research and for everyone else that would like to know.

 

Mine is pretty cold... probably too cold due to timing being advanced too far. I am using an s-AFC to tune it and leaning it out 38%. Anyways... at the top of third it gets to around 800 C. Sometimes it is closer to 780 C. This is on pump gas (93) at around 19 lbs of boost on a GT35R. Car is right around 380 HP I would guess. It beats a DSM with 350 and lost to a 425HP Supra (We were doing freeway pulls starting at around 30MPH up to 120... he finally pulled in front of me at around 115mph... before that I pulled in front of him a ways due to my car being lighter I suppose). Hope that is descriptive enough... car is tuned horribly and barely idles. The AFR is around 10:1 after around 6250RPM mark so it is really way to rich right now.

 

thanks, thats some great info.

 

How many degrees timing advance at 4500 rpm and 7500 rpm at 19 psi?

 

Thats the problem... I have no idea. My datalogger refreshes too slow to catch any usable timing points so I havent used it since the car was damn near stock. I am subtracting 38% airflow (Fuel) at the top RPMs so I am assuming in the low to mid 20's?? at 7500. I have not a guess at 4500. The car doesnt have any signs of detonation on the plugs and pulls harder than hell... I usually try to keep a 50/50 or more mix of 110 with the gas until I decide on the standalone I want to go with.

Perhaps the car is running ok from one of Curt Brown's old tricks non-advertantly... inducing the car to knock which in turn pulls the timing to where he liked it. I dunno but the stand-alone should be in hopefully within the next few weeks along with the roll cage.

 

any body else?
