Small update

Car is running.
Keeps blowing tubes off so not making any "substantial" power yet. Going to try and make it to the track Friday to finish my tuning.

What's your version of substantial power. What kind of boost are you reaching when it blows the tubes off.

Well, it blew the tubing off running 5800 rpms @ 8psi of boost and was over 500 rwhp.



Couldnt keep it on at anything over that. Im building a brace now to hold the tube on at the TB.

try a t-bolt clamp so it can dig the rubber into the "dog-knot" on the TB.

dont forget that this was @ a 9.5:1 a/f ratio.....so NOT ANYWHERE IDEAL haha

that thing is gonna make some sick power when tuned....just remember if you dont have the power you think you should be gettting, just up the boost

It was running 9.5:1 AF ratio because the first time that it blew the tube away from the TB, it pulled the splice that I had in my IAT sensor wires.

It wasnt running with the IAT which is a pretty important sensor with the speed pro ECU.

Hoping that I have all the problems fixed for this week at the track. hehe

Sounds like its turning out sweet. My speed pro only uses the iat in alpha n mode, is that what your using? Or maybe I need to hook my iat up??

IAT is included in the base calculation performed by The Speed Pro unit in Speed Density so it is critical that a correct reading is given to the computer.

Another update

We got the brakes lined out with the right fittings on the prop valve. Got my welder back and tacked a tube nut on the pipe and used the old tie rod that I had originally bought for my alternator tensioner.

Here are some pics.
Hope to test them Friday night at the track!

What brake MC is that? I've been wondering if I could replace my stock one with one off of a full size truck just because it has the fittings on the other side (the stock f-body one has them on the engine side), but can't seem to find an answer.

Stephen 87 IROC from the drag racing forum posted how to do it.

take an S10 manual master cylinder and the pushrod assembly. You take and cut down the pushrod and thread one end for a rod end. take the brake pedal out and drill a hole 1" higher than the factory pick point. bolt the rod end through there and adjust till you get good pressure on the brakes. We had to recut my rod once because it wasnt allowing the piston to fully travel and wasnt getting fluid to the back brakes. Fixed that and now we are gold.

Re route your lines and you are done.

Thanks. For some reason they look so much bigger on your car than mine and I run a MT 28x11.5x15 ET street. Can't wait to see more of your car!!
