11 sec GT40 build....

  • Sponsors (?)


I would have been happy going 12 anything honestly. It's lost 10mph and 1.2 out the back. It didn't like something that was changed
That sucks! With me being lazy(don't want to look at back pages) what did you change? I think I remember a MAF change,inj,headers. Have you thought about getting a data logger etc to see what's going on? That's def a big change obviously.
 
think i figured out what my issue was. not sure how it got the way it was but its fixed.

my base timing was a bit on the high side. higher then id even run it locked out. 40* spout out
 
im not sure what im more confused by... HOW it got like that or WHY it didnt knock with the timing that high.

not sure what the plan is right now. getting to the track before they close is going to be tough. and do i want to keep the T5 in it till it goes 11's or just say screw it and put the C4 in it? auto or not the motor is coming back out this winter to make a few small changes to it that id prefer to do on the stand and not in the car.
 
thats what im thinking....

anyone know what
a 90 T5... shifts smooth
pro 5.0 shifter
stock flywheel
5 speed pedel assembly
stock cable
quick release quadrent
firewall adjuster
stock bell housing
Zoom Kevlar clutch has about 500 miles or so on it.

800ish sound fair?
