One of my absolute favorite G3 Hemi conversions that I’ve ever seen. Well done!

That is a $hit ton of mph for those ET's....Congrats...Those MPH are showing you the real HP potential and its very impressive.

The reaction times need some work though.....

Ghinmi- How many pounds of boost are you running? That thing is flying.

and what led you to switch to a compound setup?

Yes, huge mph for the et. But ultimately it's not a drag car and I'm still working on the launch strategy. Being a clutch car, changing the launch makes huge changes to the reaction time so I don't try to hit the tree until I have the launch locked down. We do mostly flashlight starts anyway.

Those passes were on 21-22 psi in 4th. A little less in 1st and 2nd.

I wanted more power than the small single could make and I didn't want to give up the responsiveness or low end boost.

Have you done testing to see how broad the boost range is then? i.e. boost comes in at 2000rpm and 'lasts' until 6000rpm based on exhaust backpressure that you deem acceptable? Are you desiring pretty low rpm boost for when you autocross? Still lots of work to do on my car but I settled on a VSRacing 76/75 with a T4 1.25 a/r to try to find one responsive but not choking.

By adjusting the bypass gate I can make it do essentially whatever I want. The way I have it set right now it comes into boost 1300-1400 rpm and holds till the rev limiter at 6500. I can have it make 20 psi by 2000 if I want to. Or I can make it lazy like a big single turbo car. I had to do this on a very tight autocross course just to kill the power.
