I didn't know if you guys seen Mike's new numbers, he took the Lt4 SC off which made about 750 rwhp. Put the 2650 back on added some boost and timing on full E. Made 930s, he then added some more timing and made 863. I don't think I've seen anyone make that power with a stock Lt4 engine; he also still has the stock exhaust with cats. I sure wish I'd had forged pistons in my 2022 Lt1, we could have made a shit load more power, just couldn't take the chance on breaking pistons again. I think his total timing was about 26 and 22 psi of boost. Sorry I haven't been around for a while, I sold my truck with the LS swap and really haven't built anything since then. Had a few medical issue and really haven't wanted to mess with anything.

Good to see you back my friend!

Cool build but you won’t be living with a stock LT4 and 22 psi of boost for long lol…

I doubt Mike will leave it like that driving his C7 daily. I'm sure he was just testing the limits of his fuel system and stock Lt4, plus working on some new stuff with the reflex. He said he was close on the port injectors also and was going to move up on those.

Oddly, enough ... It is on my wish list.
The car is currently at Killer Performance getting the low side upgraded, forged internals, more boost and a few other goodies.
I wanted to do the THPSI plate kit as well.

It's easy HP for the small amount you spend. It was sad to hear their GMC burned down at the shop. It was a very cool build. Good luck on yours.

Thanks! Hoping not to have any issues with the extra 2-3 psi boost, I've always run 19-20 psi boost with the 2650/port on it which has been the last 20K or so miles, engine/car currently have 53K miles on it. I do need to get the low side in line and I'm swapping to a set of 775 cc/min injectors as well on the port side to get the pulsewidth down a bit.

I'm planning to push it a touch further with a 75mm upper to see if it will cross into the 4-digit HP zone then backing down the power a bit at lower vehicle speeds using boost control.

Go for it, I had no doubt in our talks that was coming. Hero pull it Sitar.
