BGTV8 VQ40HRGA Race engine build

BGTV8 · 01-11-2024, 03:35 PM

So the final update ........

Stroker engine is in the car and has been run-in and tuned on the dyno.

It made 390Nm torque at 8200 rpm on the most aggressive timing but we dialed it back a touch and settled on 370Nm at 8000rpm in the interests of reliability. All done on our hub dyno.

It sounds angry (sorry - no sound bites yet).

Have configured traction control into the Motec as I suspect we will need it.

Testing traction control at Winton Raceway on 2nd Feb before first race meeting on 16-18 Feb as the first event of the season.

Its only been 8 years since starting the journey but we are finally here.

Assuming 12-15% parasitic losses thru trans and diff, I reckon we have around 490Hp at the crank. Pretty happy for an NA engine running 102 octane fuel
