I had posted in the racing section that I went 14.20 @ 103.9....spinning in 1st and 2nd. So...I decided enough is enough and bought a set of 215/60r14 BFG Drag Radials for $190 pair Brand New. At work I had some 14 inch steels from a 88 Celebritry (FREE) and mounted them up.

I also bought I Greddy Profec b Spec II boost controller a month ago and I love it !! Low 7.5psi and High 10 psi
It took a while to get it tuned in but its as good as I can get it as of now.

I only test fitted the 1 wheel to make sure it fits and it does. So, I decided to take a few pictures quick.
Any one have a suggestion on a good tire pressure?










13s or Bust !!!

mmmm, but I was expecting better times out of the Hahn kit for some reason. Im sure the tires will help you quite a bit though.

yeah those will help alot. just heat them up nice

A B&M short throw will also help!

Had one and made no difference. Actually it tore the crap out of the boot and I can shift the car just as fast with out.

GM badge FTW!! can't wait to see 13s

very nice LS Sport

hmmmm you should be able to pull 13's with what you have for sure before the radials. i would suggest starting at about 14psi and see how they feel, then maybe drop them down to 10. i had the same ones on mine and ran them at 12 launching at about 4K.

Your going to want wider tires......

Should have went with something like the M&H DOT Slicks

$95 a piece, not bad. Mind if I ask where you got them?

Now up the boost

Nice, I was also thinking wider tires.

Jack Williams (wholesale) - I bought them through the Chevy Dealership I work at.
From what I can find that size is hard to come by.

Not a good idea on stock bottom end. It's pretty much a crap shoot if it'll hold up.

If you are at 8psi now, I would slowly increase the boost and mess w/ hpt to increase fuel in a slight amount until you're afr's come back into check. Increase in 2psi intervals to be safe. That way if you do lean out it won't be that bad. Let's say you're running 11.5 afr's right now, which is slightly rich but safe for stock internals, you up it about 2psi, you're afr's should go into the 12's, not terrible but bad enough to cause damage for an extended period of time. Also as you are increasing you boost make sure you keep an eye on knock and are pulling timing as you see knock. At the afformentioned 14psi you should have to pull roughly 10 degrees of timing, not a really smart idea, you're egt's will raise quite significantly with that amount of timing pulled from the engine.

As it sits right now, with only 8psi outta a 16g you should actually be able to have slightly advanced timing, maybe 1 or 2 degrees.

BTW, nice toys lemme know how that profec works out for ya, I'm looking into a ebc and can't decide between the greddy or aem unit.

My mistake I misread the post, thought it was about boost pressure not tire pressure.

i would suggest mounting the tires properly. they are directional.

LOL, Thats why I said in my original post saying "I only tried 1 to make sure the rims would clear"

I know they are directional....I mounted them myself and saw the little "direction w/ arrow" on the side wall.
