Courtesy of SpecialTool... The run is with a Vitesse Stage 3, 2.5L stock engine, 3" exhaust, dual port WG, MSD, race fuel at 25psi boost.

This is a load dyno, they usually read lower than a DynoJet.. The 2 dips that are caused by a worn/damaged distributor rotor..

I think there is some left there... We will use this run as a base for the Vitesse Big Valve head, which SpecialTool is getting.

What kind of gas do need to run 25psi?

Nice numbers!

Mike S

What caused the distributor rotor damage? Is this a casualty of high boost?

Ian Carr

no just being worn...

NZ951

Rotor schmotor! I am deleting that weighty piece of junk next week

J Chen

Wow look at the boost curve. It would be
great to have a turbo that produce those
curves on pump gas.

NZ951

Where is the boost curve?

Ian Carr

Right there^



I gota say being there(i wish i really brought the video camera!) was pretty cool. Just listening to that car is insain! vrrooooooooooommmmm psssshhhh

Also he is running like 75% pump gas 25% race gas or some thing like that

NZ951

I see Torque, HP, O2, and Speedo. No boost.

Ian Carr

o sry nvm then , ST probley has it on his data logger ? ST WHERE ARE YOU!?

J Chen

Aaah NZ,
You woke me up on this. I should have said power curve.
Hey, have you spoken to your buddys about the SR TBs yet ?

NZ951

Had some prelim discussions... need to get scientific on its ***, maybe this weekend.

Boost is 1 bar at 3156 RPM. This was my top priority - lowering spoolup.

I lose 4-5% power using my pump gas timing map.

The rotor tip was blasetd into nothingness by the MSD. I suspect from making dyno runswith stock wires 2 months ago.

J Chen

Yeah Special, my guess it's to do with too much
resistance in the stock wires.
