BGTV8 VQ40HRGA Race engine build

Spooler

The Emtron is really good. Right up there with the Motec. Just about done. Need to setup the safeties and fun features. It's close.

Well, the car has had its maiden race event (with standard engine)

FB post is here - hopefully you can see it

Apologies for FB SNAFU



So Victorian Sports Car championship Round 4 has been run and the maiden event for the #50 ProdSports Z34 went to plan with an untroubled day.

Times were not anything special (Keith Flanagan you lap times are not threatened yet).

The mega wing is too draggy for a standard engine - I picked up 15kph on entry to T1 by taking 1-click of wing out and will try removing one more the next time at PI.

The chassis is brilliant - T1 mid-corner improved to best of 187kph and it feels like it could take more and this is on 6 yo R-Specs. 1-click wing less made no difference to mid-corner grip and it felt like T1 could be close to flat - that's the level of confidence the chassis inspires.

Brakes are similarly outstanding (AP six pots on the front on 14.25" rotors and 4-pots on the rear on 13" rotors with CIRCO pads. In the end, I was diving inside 75m into Honda and still it was stopping. T1 I was braking after turn in which is inside 50m and there was not a hint of slide mid-corner. Note that speed on entry is down though as it is draggy.

No slicks until I have a dry-sump engine installed - planning on that for Island Magic event at the end of Nov this year so still significant grip to come
.
I am having to unlearn nearly 35 years of experience based on my "other" car as the Z handling and grip is just so superior.

A bit more grunt and optimised drag and slicks will see the times drop.

Off to the final round of our state championship on 15-17 Sept

Some video clips of Quali last Saturday and link to the Streamed TV broadcast of the 30-lapper and 12-lap final race - both on Sunday. Our category starts at 2h 28m 50s for the 30-lapper and the 12-lapper starts at 5k 12m 42s

Quali in 2 clips from Saturday. My camera only records in 10 minute lumps because it is 4K – I need to set it up to record at 1080p so the files are not so large

Sports cars are at 2h 28m 50s for the 30-lapper and the 12-lapper starts at 5k 12m 42s

Plot being hatched to get the fat engine in the car for our last event in November

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

Elmo370z

Man that’s awesome. Cant wait to get some sound bits.

Rusty

390 Nm is 287 ft lbs. That seems low. I'm making 289 ft lbs with 334 Hp N/A at the back wheels.

Working on two things with my Emtron. Getting there. Glad you are enjoying your car. It will be a blast.

@ 8200 RPM! Holy crap! That is a ton of torque!
