What kind of timing are you running base on motor and n20 for the duster. I would have to think it’s harder on parts with high compression and n20 then the turbo

I run 34 total and pull 10 degrees on the sauce.

Thats awesome, thank you for sharing. Are you turning the timing down on the street with both to run pump gas, or driving them on race fuel? I think truly anyone pushing stock block setups has to be very wary of detonation,regardless of engine platform...sometimes less is more, and this is one of those times for sure. Is the duster also a stock stroke 70 block?

The turbo car since it has Holley EFI and its 9:1 I run 45-48 degrees at part throttle so it will run cooler on 91 octane. If you go look at my build thread you can see how I set up a dual fuel system. I run on wastegate spring pressure on the street (2psi) and use a C02 powered boost controller on the track. BTW when I forget to turn on the C02 the car runs 10.30/135 on 2psi lol (436” motor now). The Duster runs on C14+ at all times because of the compression. The Duster has an old forged crank from Mopar 3.58 stroke 4.070 bore which makes it 372.
