Ah that sounds serious. I have the Holeshot Stage 3 kit with the GT30-76RS Race Turbo. Should have 550hp at the crank, but I drive it on 8,5 PSI for road use with pump fuel, it gives about 325-350 wheel horsepower. For track use I can go lots higher with the PSI's, but on public roads it is way more than enough this way.
What turbo are you using?
The swaintec ceramic is the way to go!

I had some trouble finding a nice solution for the clutch slave cylinder and found a really nice, not too expensive, solution in the handmade billet slave cylinder from Holeshot, it has 3 point-attachement, and has room enough for a (very) heavy duty chain, which you're surely gonna use. i'll try and attach a picture of it. It is really nicely made and very robust. Before this one I had an other, but I kept some problem with disengaging. And bleeding is very easy with the nipple right on top.

Sounds like a nice engine build - what sort of internals are you running?

That slave setup looks similar to what Z-Cars supplied me, a bit different though, but looks well engineered. It's good to know there are options out there though, so thanks for the pics.

Yes, I'm running a 630 chain...

Recent pic, I've been wrapping the headers, turbo and downpipe with ultra high temp wrapping, wish I could do the coat you have, that always looks so good!

and last pic with new Waste gate, this one is more easy to work on compared to the old type, I can swap diaphragm in 5 minutes if it would melt, but i'm pretty sure this one is up to the job, as you can see my downpipe goes the other way around, so the WG has lots of heat to cope with. Before only the headers were wrapped, not such a good idea!

Is that a Knight Motorpsort frame you have there?

Jep it is. Wayne did the entire build on this one! I only bought the car and repaired some minor issues( which Wayne was not responsible for). I am still in contact with Wayne, he was a great help when I had to pull the engine and crack it open, I didn't do any bike engines before, but it went very smooth with some help.

Johan,

Looks awesome. How important are you finding the holes you cut in the floor below the turbo installation as far as controlling heat?

I think those holes are really important, 1 inch away from those heat sources is the steel plate with heat resistant reflecting material to separate the engine compartment from the cabine. Without the holes, the only way for the heat to go is up, with the holes it also goes up, but there is some flow to the back i guess. I also have holes in my fiberglass back panel for the air to go out. I don't know it for a fact, but I think it decreases the temperature for a big part.
And it saves weight...

I see the insulation wrap on the header, turbo, and exhaust. Is this a good thing to do? Is it for performance or creature comfort?

Both, if I don't do it my wastegate melts from the inside, my ass gets toasted and on the performance side, they say when the heat stays in the exhaust the flow is best and the hp are highest.

Here are some pictures from today to show how the chassis assembly is coming along...thought it would be cool to back it out into the snow covered driveway. I'm working on aluminum panel fab for the next few week. The car is sitting about 0.5" high in the front and about an 1" high in the rear in these pics. The wing probably looks huge in these pics, but keep in mind I have an 8" splitter with front wheel well diffusers and full diffuser in the rear to balance the aero load.
