BGTV8 VQ40HRGA Race engine build

BGTV8 · 05-19-2023, 05:56 PM

So we now have overcome pretty much all of our teething issues.

1. Getting the M150 to understand the VQ37 engine has been a massive challenge. Not a lot of knowledge in this part of the world. Has taken months (my engineer is a personal friend and he has worked on my car for "mates-rates" which means he puts time into the car when he doesn't have other cars to work on
2. We are running 6 x Jenvey ITB set up with a single Bosch Motosport DBW motor and getting this set up to advance the throttle blades on each bank sync'd has been a challenge - you have no idea how much overall torque can be affected by one bank leading the other by as little as 2%
3. The engine in the car (original still until we can test the car and sort out a chassis setup we are happy with) has not run for 3 years and we had some CAS and cam control issues to resolve

So, at least you can now hear the 6 x ITB induction noise at WOT and full load. Best described as orgasmic.

We are off the Winton Raceway (Victoria, Australia) next Tuesday for a systems check (chassis setup/handling, ECU/Dash config, cockpit ergonomics etc). We are only running R-Spec tyres for the moment and won't put slicks on the car until the dry-sumped engine goes in when sorting is complete. Provided Tuesday test goes OK, we are running in Production Sports Cars at The Bend Motorsport Park in Sth Australia and the program has the 4-litre engine installed for Island Magic at Phillip Island in November.

A couple of video's of WOT throttle tuning are here:
