Default First passes this year !!!

Well after a long battle
I finally made it to the track and had everything i needed
First pass drove in from a hour and a half jaunt from my house
and let her cool down
stock trim 12psi of boost some ET streets
pulled a
60' 2.229
330 5.716
1/8 8.548 @86.93mph
1000 10.956
1/4 12.973 @111.52

Not too shabby for the first pass featherd the throttle out of the hole
just too see how the slicks hooked up

Second PASS
60'1.902
330 5.114
1/8 7.704@94.81
1000' 9.937
1/4 11.836 @118.59

Stock trim no wieight redux 15psi of boost with ice in the intercooler
launching at idle

I didn't take off the exahaust which is worth 60rwhp on the dyno
With brake stalling some and no exahust i think 11.5 would have been close

This setup has way more in it for sure just need some more boost and some C16 race gas and a few other goodies

None the less i am very happy with it so far
There might be some vids tommorow if i can salvage some of the footage ...the Camera men sucked !!!!

Thanks too those who helped me on the way to the 11's !!

Sounds like it's time to install a T400 with a transbrake.

Good times for the first time out. That '60 tells me there is ALOT more left in the truck as it sits.
