BGTV8 VQ40HRGA Race engine build

BGTV8 · 02-19-2024, 02:18 PM

So our first race meeting of the 2024 series has been run - Victorian (my home state in AUS) Sports Car Championship.

Car ran like a train after we got rid of the head-fork that was DBW throttle (Sasha Anis told me several times that would be how it ended).

I ran as high as 5th after some of the 911 Cup Cars fell off after they touched but finished 7th outright and first in class.

Bolted on a set of Yokohama A005 slicks and they work the best of Yoki, Pirelli and Michelin. I might try a set of Dunlop slicks in due course.

The only issue is pottering back to the pits after the feature 20-lapper the oil pressure was a bit low (oil temp after a 30-minute race was 112 degC) so I have to get a smaller pulley for the dry-sump oil pump to spin it a bit harder at idle and just off idle. Have to revise the oil-cooler ducting as well and possibly a larger oil cooler at the end of the day.

Tried a set of Circo (Japanese made by Winmax) M207 endurance pads and they were brilliant. Braking performance is simply outstanding.

I'm really happy to be enjoying the car - it has no apparent vices although I am not at 100% yet given it is such a different animal to my old race car.
