Tommarrow Is The Day!!!!!

Well towwarrows the day were taking the blown gt to Tri State Raceway in Earlville iowa. Im siked! I have no idea what to expect out of it i hope it does well. I wish there was some mustang clubs around here.

how did you do?

.60.........1.773
330........5.136
1/8.........7.960
mph@1/8.86.82
1000ft....10.402
1/4........12.473
mph.......108.41
this was my first run of the day, my second run pulled a 15!? its not running well under boost im still testing stuff and cant find a vac leak. any help?

I am getting major detonation at aroung 5000 now. im thinking its too lean at high rpm's with the supercharger. I think i broke something,thats why im inquireing on new engines. I was pushing it really hard.

yea you probably broke something. what are you using to tune fuel and timing? 12.4 is pretty fast nice run.

Fuel: t-rex fuel pump, vortech fuel management unit
Timing: msd 6btm boost retard
yea it was a good run and im happy with it, but i would like to run that consistantly without breaking stuff.

yea not breaking stuff would be ideal. i'm sure you'll get it figured out. how many miles were on the motor when it broke?

about 80k on the complete rebuild.

Its not completely broken, it starts and runs and drives just fine. i get detonation at high rpm is the main problem. i have a boost control (msd6btm) i called msd to make sure i had it installed correctly and i do. so the only thing i can think of is the fuel is leaning out. i know its pumping it but i think i need to upgrage the injectors.

What injectors? What fuel pressure are you seeing while boosting? Do you have a wide band? What octane are you using?

I had a T-Rex on mine, with the intake fuel pump as a band aid. You might want to buy a dual 255 set up, or an Aeromtive 1000a.
