Anybody running 60# injectors smaller pulley and a tune only? no other mods. If so, what size pulley with 60#'s?

 

i ran 2.5 and 60's for 7 months

 

any problems? what kind of numbers?

 

what? w/o cooling mods?! does your engine like being fed a blow torch???
sorry im so skeptical but thats hard to believe you did that, must have had a very conservative tune

 

tune was 23* timing and a 12.4 afr on 93 pump gas

the car was fine, i don't beat on the car much. It did see the track once that year for like 7 runs and was fine.

never dyno'd back then

 

12.4 afr?

 

yeah

 

what is a 12.4 afr? I prolly know this, but can;t figure out the acronym.

air fuel ratio, nevermind

 

bingo

 

thats rich though? you could get more power out of it if you leaned it out couldn;t you?

 

haha lower the number the more rich. That is pretty damn lean for a boosted car

you could not pinch much more out of it with out supporting mods

 

lol, 12.4 afr is a pretty damn good afr. any leaner go boom! and any richer you probably would just lose power.

 

11.5~11.8 is safe but good for power to, 12.4 is pushing it. you don't make anything after that

 

ok i was confused. I thought lower the number the leaner. when I dynoed my car is was running at 10 lol. pretty rich but it's factory stock tuned. I am gonna go aftermarket injectors, aftermarket pulley, and tune time tune I think. Any advice for a powerful tune but a safe don;t blow up my engine tune?

 

the tuner should take care of it, 11.5 afr is fine and 16 * timing is cool to. matt knows what he is doing and will take care of you don't worry

 

did you go to tune time? and is it worth the drive from nazareth pa? (lehigh valley)

 

no, i tune my car and others. i have heard good things about them though from many members.

no shop would ever tune like that lol

 

tune like what?

 

on the edge. that much timing and that lean was pretty crazy with no cooling mods.

I don't even run that lean and I have cooling mods.

 

ok, this is good info here because i'll probably be getting a tune this summer and I want to be slightly educated on this. Any other advice????

 

how cold does it get around you? weather can mess with your afr and can make you run leaner in the cooler months

 

GET COOLING MODS! lol. Seriously, pick up a heat exchanger and you should be fine. It'll allow for some extra timing advance which will help out with power of course.

 

also cools iat's, to recliam some power

 

alright i'll do the heat exchanger too, could i upgrade the whole intercooler system? Gets really cold, sometimes in the teens, but mainly stays in the 30's

 

you can get a dual pass endplate for the intercooler.
