lol, when my monte was n/a on 26* 12.5 afr knockless, i walked away from the ls4 cars and pullied GTP's pretty good, they always asked what pulley size i had... i said no s/c and pop my hood lol their faces were priceless

i've been told by a few of the big 3800 power makers and a few dyno tuners that 25* is the most timing that will produce more power for the s/c 3800, 26-27* for n/a. from my experience they are correct, i may be new on here but i've been into the 3800 engine for a while now

 

Very nice! All helpful info guys thanks lol I'll have to do some reading

 

I know the guys that ran higher timing always blew their **** up. Is it really worth squeezing out that 5 extra HP?

 

Like I said before not looking for a huge hp car seeing as how I even got in trouble a lot with a grand am gt so not looking to add a lot. I think I will start with headers once I get some money saved up and start modding from there.
