When is a turbo too big?

miss spark, retards timing, add more fuel get the EGT's way up
and that spools the turbo under no load. You can build over 20psi at starting line even with GT40's.

good for a drag car - VERY hard on the turbo. you are basically causing miniature explosions to boost the turbo.

KA uses a programable nitrous system. It is designed to activate at WOT. In addition it has two rpm pills. The system needs WOT and 2600 rpm's to activate and the second pill starts the shutdown at 4400 rpm's. These pills can be changed. When the system activates it starts with a 10 hp shot and adds an additional 10 hp shot every tenth of a second for 2.5 seconds. As long as you are at WOT, the system shuts down in reverse order oce you exceed the upper limit pills rpm number.
Yes, the turbo's do boost extremely fast. The system is very smooth.

Oh, almost forgot ............. the clutch must also be fully engauged for system to activate.
To answer your question, it can be activated at will from the drivers seat.

I'm not too worried about the "band aid." Depending on the turbo's we settle on she will have anywhere between 1.0 and 1.5K hp. That is 962 race trim power.
PS.......... we are not piggybacking anything. We are not using vario timing, cams or actuators.

I like the approach that Robb is using on the cam set-up on KA!! I am going to have to take another look at my new motor build-up, since I want to run twin GT42R's on the 4.2.

I knew Todd tried Motec, however my understanding is you stayed with the modified Bosch ECU.
New motor for your tt. I'm surprised considering your 2200 lb GT40R turbo rocket. Now you really have me baffled.
