how much psi is a 3.6inch pulley equal out to?

btw awesome numbers.

 

His signature says 8 psi.

 

haha, i see that now, oops. thanks. I was thinking turbo, but it would make me mod more things then i want on my current set up. I think the vortech route is "better" for my budget and car. I just want to run with the big boys, lol.

 

Hes my friend, lives right near me....hes running the stock MAF

 

cool. now intercool it, add a 3.12 pulley and hit 430 rwhp like i did.

 

on a mustang loading dyno with the same setup,long tubes, and the 3.33 pulley i got 385 hp and 372 torque

what kind of dyno did you have yours done on?

 

Dude, seriously datalog that **** with recon and make sure your timing isn't higher than like 12-13 degrees anywhere above 3000rpm if you're running 93 octane (for 91 octane run no more than 11). Those are good numbers for 8psi non-ic, but sometimes the base sniper tunes can have too much timing. My 10psi base tune had 18.5 degrees at 6k, which in other words means detonation.

Also, I'm glad you are adding fuel, cause 12.0 is kinda lean for a blower car. Like you said, 11.4-11.7 afr is optimum.

 

Check your timing tables in your tune. Specifically your Engine Coolant and Intake Air Temp Spark Modifier Tables. Tunes should be set up to pull a number of degrees of timing based on the engine coolant temp and the intake air temp. If those values are set too high, then your PCM will be pulling too much timing out resulting in a loss of power. This could definitely be the case if you went from non-intercooled and added an intercooler and the tuner forgot to reset these values.

 

****.

 

would it be better for me to get a sniper tuner seeings i already have a sct livewire? also If i get the sniper I will be able to get on her and be fine? I am currently putting a vortech on my car. also how would the sniper tuner work seeing i have cams?
