4.8L Turbo/4L80E : 7.00@98MPH w/Videos
#31
Thanks guys, glad to help out with any info I can. Hell I got most of the setup from other guys running on here, so no secrets here. Looking at the logs about 8psi off the brakes, at 3500 i'm holding it about 60% throttle. Then brakes release timed with 100% throttle.
Fastrt, running untouched heads/gaskets/bolts. I do have polished valve covers though and K&N breathers on both.

very nice runs! you did this on your first time out with the truck. its only bound to drop. and yeah your good for 10.90's but only once before getting booted for no cage. since you got 300 miles on the setup how do you like the manual valve body on the street.

Thanks guys. Well I really op's checked the setup this week, drove to Ohio from SC for thanksgiving. Put about 1400 miles on everything with no problems. Manual valve body takes a little getting used to, but I got it down to making it feel like a full auto to a passenger. I had to switch over to 93 oct from E85, e85 was hard to find on the highway. All I can say is my truck hates 93. I had to pull almost 4 degrees over the whole timing map to keep it from knocking and made the truck feel like a fat pig. Alot of that is because I have the E85 tune Amped up over a stock timing curve because of the 105 octane rating of e85, I can get away with it. This really helps the power when out off boost, getting that 4l80E moving with the 4.8. Gas mileage with the auto is rough, got around 15.5 highway. I used to get around 21 with the stick and 93 oct. It could have been better, but i didn't mess with the tune much, just got it setup to be safe to drive.
Also, bough these last night to save the Nitto's for daily abuse only. Hope to have them in friday along with a driveshaft loop. Till then I need install some small calipers and rotors.
Quick Time Pro D.O.T., LT 29 x 11.5-15
U.S. Wheel 97-5860P 15 in. x 8 in., 6 x 5.5 in. Bolt Circle, 4.75 in. Backspace
(dont plan on running a center cap)
Question, what kind of Air pressure you guys run in these and any need for a tire tube?

I never run tubes in any slick on any car. I'd say start at 14psi in the tires, make a pass it should be at 15.5 when you get back around. If it didn't sway (bad enough to make you lift) and you spun, drop them down.
I run my goodyear 28x9 slicks at 12psi it goes straight as an arrow.
