Default Highest WHP on 81.5mm bore??? Shooting for 800whp...anyone else?

Just wondering what #'s people have made on 81.5mm bore. I will be running the turbo listed in my sig on a fully built ls/vtec with a 35shot of nitrous to help spool and cool intake temps.

EVERYONE who has any info post it up.

Thanks in advance.

what trim 42r are you using?

800 should not be a problem with that large of a turbo without nitrous.

That guy on here with the silver hatch posted 775 WHP on his setup with the PT71-GTQ (I believe), and since moved up to a GT42R. He's been a bit tight lipped on his dyno results, but I have no doubts he's well past 800 WHP. I bet there's some other racers out there too, it's just not everyone is on the internet.

it was under 40 psi.

we spent a lot of time planning out that motor, no expense was spared on that motor.

the head flowed some serious numbers.

the bottom end wasnt anything special 84mm bore.

i cant remember what else he put on his post...

but theres a reason some people are humble about their setups
