Latest track video of the widebody 3.1l 16v turbo

Indeed! I will remove the engine and check/replace the rod bearings during winter. So far everything the stroker engine is working flawlessly. My different issues during this season has been elsewhere.

Great going Gustaf! As mentioned previously, you really are getting more comfortable in the car and it's showing on the times. Considering it's a difficult looking track for our cars and you've had a few other issues, you should be congratulated especially since you're doing all your own work.

Thanks guys!
Regarding the clutch - short term I didn't want to do anything custom as that risks taking too much time between race events. Long term I don't like to go backwards so a superlight FW with motorsport clutch it is
Regarding the trigger - I've run several different setups at the front of the crank and the only good solution there is the Clewett. The other variants are crap. Stock like setup at the rear is superior in every way.
The BMW runs a RB26 engine with 680 rwhp, Porsche 6&4 piston calipers, BMW E39 rear suspension etc. Everything is custom It was his first shakedown in a long time so even with his power advantage he was close to 5 sec behind. But I'm sure it will evolve to something very quick.

Be great to get some pics of those bearing Nice work Duke! Very impressive driving and a beautiful car!

A heavier FW will slow down the acceleration and deacceleration rate of the engine. To help spool you need more exhaust energy, something a heavier FW cannot possible help with. The only way it could "help" spool is by slowing down the acceleration rate of engine which in turn will prolong the time window for the turbo to start building boost. Which in reality makes a slower car.

For cam trigger I'm using the stock setup. All 16v engines have 60-2 crank and a cam trigger setup from factory

Flywheel stores energy, not creating it and the energy stored must come from somewhere. Perhaps engine would be my 1st guess?
Only situation where heavier flywheel is good thing is when you start moving with the car in gear, stored energy from idle speed help the engine to maintain its rotation from inertia.
If someone explains with facts how heavier flywheel is useful during acceleration and/or throttle response on any car (be it forced induction or NA), I would be grateful.

So I guess you think your car is faster going uphill or in a higher gear as well given it will give earlier onset of boost vs rpm
