As some of you might know I had a fuel pressure problem for some time. Well I got that fixed haven't put a pressure gauge on it but it is not falling on its face above 75 mph anymore. So I thought I would take it to the track and see some times before I put the bigger heat exchanger, 90mm throttle body and a re-tune
Now these times are with an older tune.
1st run
60' 1.968
1/8 8.801 @ 78.682 mph
1/4 13.890 @ 96.432 mph

2nd run
60' 1.962
1/8 8.782 @ 79.000 mph
1/4 13.892 @ 94.336 mph

The second run I dropped my mph by 2 but everything else was pretty close.

 

Congrats on the new times. I went to the track tonight with a best of a 13.72 at an amizingly high 104.44mph.

Cant wait to see what the new mods bring you. You are so lucky to have AWD, i would kill for hose 60' times in street trim. I have to meet up with you at Sac raceway sometime.

 

It was good meeting you out there man

You have a hell of a truck!

I was pretty frustrated as you know and ended up with a best of:

60': 2.087
1/8: 8.98 @ 78.9mph
1/4: 13.922
MPH: 100.83
Raceweight est. 5500lbs

Looking at your slip your 1/8th mile figures are pretty close to mine. I wonrder if yours is dying on the top end or is my cam just kicking mine up?

Nomrally on FI vehicles you are supposed to gain 20-25mph from the 1/8th to the 1/4 arent you?

 

F8L,
It was nice meeting you also. I will be going back in a couple of weeks. Hopefully will have the 90mm and a few other things done. I will let you know when I go back.
And thank you for the kind words about my Truck
Mark

I know Brian. I called up PI and have a new converter being made


Mark,

I told my sister to tape any SUVs or GM trucks that ran but she only got video of me and it was a pretty coppy affair at that lol. Let me know when you plan on going out again and I'll try to get out there and tape some runs for you.

 

FL8,
Thanks I will let you know.
Mark
