Thought you guys might appreciate this.

My friends XR4Ti with a custom MS1 setup I did for him a month ago:

14psi, custom head (insane flow!!!) , bigger turbo

 

Be careful using spark cut like that, you want to spin the turbo, not shear the turbine wheel off the shaft. Aim for a smooth rich stutter so that it doesn't build up too much fuel before it lights it off. You want the burn before the turbo if possible. Unless of course the goal is fire and noise, in which case, good job!

 

I agree with you... He never actually plans on using this (it would never pass the db test) ...its just for *****

Also, this is on a complete strait 4" exhaust thats only about 3 feet long

 

If it's an option in the configuration, when it's in launch mode, richen it up about 15-20%, and retard the timing 20 or 30 degrees.

 

I LOVE those cars! So much fun. Getaway in Stockholm style.
