That’s what I thought!! My other car was the same way. Biggest gains at very moderate boost. I think we could get my sons to 5.0’s without much effort or concern. By far the most economical way to go 5.0’s I have come across. Hydraulic roller cam. It’s like starting up the tow vehicle

Last weekend it ranged from 5.36 to 5.38
It was 33 degrees in the morning so I didn’t think that was too bad considering the cold track
Honestly the 8 was probably because we pulled the fronts out of the beams. We fixed that

How did you fix it, shock adjustment?

Those shocks need rebuilt. We lowered the two step just a smidge and added a lead puck the size of my hand. It made an enormous difference. My other car we have the batteries in the nose. So we don’t generally face this.
Car is pretty new to us. S&w. Turbo for a couple weeks. Driver new to big cars this year. Did a local 777 race on the weekend. Couldn’t race Friday as driver had afternoon class. The wheels up bit us Saturday. And got beat against a .006 package one round and our driver had a .003 took .010 on the next….and last that one on a double breakout Sunday. Geeze! Lol
Driver snd car showed a lot of promise with mostly .00x lights. It was much better than I anticipated.

Has anyone ever successfully bracket raced with a turbo charger or twin turbos? Why haven't they taken off as a power adder in top sportsman/dragster like pro chargers have?

Is it possible to stage at low boost, to keep EGT and jumping into the beams down?

Is it possible to utilize a boost controller to consistently run the same ET?

Seems like if a guy could get this figured out, the turbo would far out perform the pro charger; since you can get the boost up and maintain it with exhaust flow vs Crank RPM.

Stock bottom end with 150k miles on it. Gapped the original rings and put everything back in as it was. New cam and intake. s475 turbo clone from ebay.
13 psi the other day netted 4.86/139 on a not refined tune, and a converter that is most certainly too loose. No reason this shouldn't be a reliable 4.90's bracket combo.

Liked! It's neat, different & "low budget".

IMO, I don't see very many, if any consistent competitive turbo vehicles in bracket racing.
