Message Ok, ok, sorry guys… it was only 429 RWKW / 575 RWHP, but 580 RWHP was easier to remember :)
The guy who done the dyno (Steve) & setup of the ECU… First he asked why I spent so much time & money on a VG30DETT, he could have supplied me a RB26 for half price…
After the tune he said he was very surprised & impressed at the power output….

Something else that will make you even more suspicious … Altitude, I am close to Johannesburg which is 1433m / 4700ft above sea level
I know each dyno may read differently… Steve is no salesman so he has no need to change power-output figure to impress people.

I know this is a lame comparison but, I own a Chev UTE (pick-up) with a LS76 – V8 normally aspirated. It’s got 320 RWHP.
If I would compare the 2 against each other, the Z is so quick it makes the Chev look as if though you hooked reverse… Yes it’s also blue

The only internals worth mentioning would be Gas-Flow of the heads – we completely removed the valve-stem guides from the air passages.

We have a problem with the boost… Max boost is 0.9bar. Anything over 0.95bar the internal waste-gates open. The actuators on the JWT BB700 are not strong enough to keep them closed.

Sorry, No colour code for the Blue…
We mixed something until it looked good – 3 layers base silver, 2 layers Blue, and 3 layers Clear

In the photo’s the hood was not closed – hence the gap between the hood and the nose. When closed the lines are quite smooth. As for the air intake in the hood - it’s for cold air which is guided past the intercooler directly to the radiator. Zero overheating problems

A Closer look at the Lower Air–diffuser
I don’t know if it works…. But all the theory has been applied – later I will attempt to make the entire undercarriage smooth
