Hi!
I have not had the car/engine tested for power, so i dont know the excact figures.
I only rely on what the previous owner claimed.
He had the engine tested,but it was a small testbench which maxed out at 200Kw (272 hp), and this engine developed that power at 4500 rpm.
The peakpower at 7000rpm was only stipulated at 370 hp, due to the capasity of the testfacility.
The transaxle is a modified axle taken from a Audi A6, with CV-joinst in each end. The standard one would turn into spaghetti with this power!

Thanks!
Yes, the r/h manifold started leaking. Annoying sound!
Have to fix it before the next race!

Racing update:
Attended Race 3 & 4 this weekend.
Got Pole Position in Qualifying, but the engine cut, and i was not able to fix it before Race 3...
Found some wiring-faults the next day,
, and was ready for Race 4.
Had to start last with 23 cars in front of me.
I was ready to push hard, to see if i could make it to the front, where i expected a white Ferrari 348 to be...
Race was 9 laps:

Wow great driving! What happened to the 75 24V? Is he modifying his engine even more?

Wow, that guy in the Ferrari was really playing a bit rough... Looks like the tyres turned to shit though.

He was on holiday in Italy...which really helped making this journey from the back to the front possible!
As far as i know he has not made any changes to his engine...yet

Found a video of the race you missed. From a 348 CH
https://www.youtube.com/watch?v=-w9qgqmdpfQ
That grey GTV6 is quite fast, 24v? On the straights it was faster than the camera car.
