Highest hp on 427?
Highest hp on 427? Ok, my dad talked to some guy at his neighbor's house this weekend with a vette not sure if it was c5 or c6. But anyway it's got a n/a 427 that he claims to have 900 hp. It's a black vette with black wheels and was shop built. Has lots 2 nitrous bottles in the back and 2 quart container under the hood with race gas in it. So he's running on pump gas and still has a/c and such. Is this even possible? I say maybe with a big shot, but not just straight motor.

SAM( School of Automotive Machinist) built a 1000hp na LS motor for their race car. So yes its possible to make that kind of power but I doubt the vette in question is making that number without the bottle. Maybe there was a misunderstanding in the conversation? 900HP with the bottle is not that hard to accomplish.

900 all motor on a 427 is pretty hard to do if not impossible. Some other factors need to be cleared up.
900 on a 427 with any power adder is pretty easy, well not easy, but a little money and it's done quite easily....

I can see it making that power on the bottle. ~600 on motor and ~300 with a dedicated fuel system and a ~300 shot isn't hard to believe. I have a buddy that had a Z28 and a 383 with a Nitro Daves dedicated fuel system with direct port that was putting out pretty good power.

the 2008 set up for our '99 Camaro was a 427ci C5R, it was making around 940HP N/A to the flywheel. The new set up for 2009 has a 433ci LSX block w/ C5R Heads and we made 1001HP N/A to the flywheel. Its possible to do, but not streetable what so ever.

Hey y'all thanks for the help. This guy is wanting to drive this car to the Texas Mile, which is a good drive from here, so it is streetable. Also on the track he said it went 11.1 with a 2.5 60', which I wasn't really impressed with. So yeah I think my dad heard wrong I think it's 900 on the bottle. Or he was just running his mouth and thought no one would know better.

900hp with a 427 is possible. It all depends on how much money this guy spent. are you sure maybe this car wasnt boosted? There are a lot of Z06's with forcedinduction out there with well over 800hp.

Yeah the car had a high trap speed, don't remember exactly. There was for sure no boost on the car of any kind. Mostly I was just asking if 900 hp was possible on a streetable car. I don't keep up with the big motors since that's way out of my price league anyhow. Most of the n/a cars I found that were streetable were in the 600 range.
