Well Done Rasta.

You need a Standard Blue Streak distibutor cap to match all that blue.

It was 171 bhp and 175 ft/lbs @ 12 psi. With a conservative drive train loss of 15% that puts it at 205 hp at the flywheel.

Looks great rasta

as for the battery relocation, did both the positive and negative get run up to the engine bay in 1g, or is the ground just a short run to something solid on the body in the back?

Ground goes forward to a starter mounting bolt.

Well Done, Looks Amazing!!! Having been working on the 951 since X-mas I have a new respect for anyone with the patience to work on a turbo car. There is so much extra crap in the engine bay you need 3 elbows per arm and a lot of dissassembly to get anything done.

Are you still running CIS? Have you got a wideband installed? I'd be very cautious with boost, the last thing you want is a lean fuel high boost situation, all that work down the drain...

Based on your questions about the relay for the electric water pump, I assume you have it running continuously when the motor is running.

Any thoughts about using a pressure switch or a temperature switch to activate it? A setup similar to the radiator fans might work well.

Paul, I did consider having the pump run only when boost was at a certain level, like above 5 PSI. With an air/water system, though, intake air passing through the core lowers the coolant temp when off boost, so I decided it would be better to keep it circulating.

Chrenan, I am still running CIS. I haven't increased boost much over what I was running with no I/C (10-11 PSI), and don't really feel compelled to. The car is hauling ass.

C'mon man, everyone knows there's never enough.. Drop 250 on an AEM UEGO, install and crank the boost up to 17-18 psi!

James you're a man of strong opinions and I got the feeling you already had a pretty good idea of what you wanted to do so I didn't feel like trying to tell you anything otherwise. Looks like you got it dialed in fairly well on your own.
You have the right idea about keeping the pump on constant too.The pump isn't designed to be short cycled.

Which switches are you talking about here? I have a funny problem with my SI 931, it starts fine cold and warm but doesn't even ignite once when it is "halfwarm"...

good point about the TB switches....i've noticed that at WOT the car does not pull as good as when less pedal is applied. Thanks for the flying advice

A no-start when "halfwarm" can be due to the CSV - it might be heated enough to not be activated on the restart attempt, while the engine sn't yet warm enough to restart without it.

I'm pretty sure you'd only have the throttle switches on a car that has the o2 sensor system (lambda system). The switches are to tell the o2 system when the engine's idling, or at WOT.

Thanks for the good advice!

Well I don't have the switches then, no lambda system on my car. Thanks again for the info.
