Rotrex charger setup
So I took it out for its first proper run last night to get some logs to send off.
3rd gear pulls were giving IATs of 30c and a boost pressure of 15.9PSI -
- I think when tuned this could make a lot lot more than 400-450 hp. It already feels very fast, I have spent alot on the suspension setup and it was spinning the 255 R888 r compound tyres in 2nd gear!

Razzle, what size pulley are you using to get 16psi? I'm waiting for Richard to reply to my email so I can transfer funds and get this kit over here
in the states.

I had Mase tune it using the air inlet restrictor on normal petrol a couple of weeks back.
The inlet restrictor was used as the cars primary use is going to be for track days. Unfortunately it was a little too restrictive and max boost pressure was around 12psi.The Hp flatlined above 7.8krpm and as far as i know the c38 rotrex was just getting into its efficiency band when it got suffocated!

TBH it still feels pretty quick. I left the rolling road and did a lot of motorway driving to get to a track on the other side of the country. I was in convoy with a v10 m5 and that wasnt any quicker till around mach tuck!, I wasted a 997C4S and also a C63amg on the same trip to/from the track.
On track the car performed excellently, ive got a few crap vids in my sig below (with a standard exhaust on). The temps stayed nice and low, water temp never went over 80c and the highest Oil temp was 210f after 20mins of hard track driving.
Im going to get it retuned in the new year with water methanol injection and no restrictor. It will be with a single 550cc nozzle spraying before the throttle body controlled via a switch to activate the AEM NOS map. That should make some interesting numbers, 6 more psi and aggressive timing
it 'll be pretty good for drag and street racing then !
