boost

about 10 psi, also had a leaking exhaust manifold which didnt help. I fix the Exhaust leak when i got home took it for a spin then crunched the box. i picked up a couple of psi after fixing the leak so i would assume an extra 10-20 hp

Hey Paul

Haha its funny you just posted this I just read the whole build up thread on your car at ausrotary. Thats some nice work and a ton of effort you have put into your car.

A little off topic but what do you plan on doing with the car to need such a complex front coilover set up. And what do you plan on doing for the rear.

Your car is sick, maybe mine will be as nice one day. No more Purple?

-Alex

my 7

Ive always wanted to compete in hillclimb, motorkhana and track day events so thats why ive built up the car like it is. I had a track day last weekend but blew the box and wasnt able to attend. For the rear end i will one day like to do a panhard rod conversion and delete the watts link but at this stage its just a standard rear with heavy duty lowered springs and gabriel struts.



the police are fairly harsh on moded cars these days so i will have my fun off the street.

Paul

The car looks sweet, and the numbers look sweeter.

You should definately make some videos of that thing.

(love the hood idea, too. I've been planning that with a spare hood)

Also, keep in mind that Dyno Dymamics dyno's commonly read somewhat lower then Dynojets.

Where did you get the coupler to go from 3" to 2" becouse I am working on a 78 and my problem is that I have a 2" out from turboi and in into carb and my intercooler is 3" in out pipe.

Mindaugas

P.S. Nice numbers I bet its a lot of fun to drive
