Highest N/A pump gas motor

I have a 427ci ET LS7 engine and a 449ci ET LS7 going together in a few weeks. These should be fairly stout.

What's the status on our 2 new motors?

You get the thing finished? I live in S'port as well...
SAM motor FTW. That thing is a monster as is. Not to mention they already have a bunch of parts they're going to through on it to step it up. Solid roller, sheet metal intake, ported heads...

DOHC 7.7 litre V12 with 880bhp production version on 95RON unleaded (equiverlaent to US 91 octane).
Some where hitting 1000bhp on the engine dyno according to some TVR engineers, but that might have been on higher octane fuel.

Those things can make 1000 RWHP easy on pump gas! Supras FTW!

Also, 1000 rwhp in a Supra does not guarantee stellar ETs. The common saying is "what do 400 rwhp F-Bodies and 1000 rwhp Supras have in common? They're both 11 second cars!"
Just don't try racing one from a roll. You'll get your *** handed to you!

I have never ever seen a supra make over 1000 rwhp on PUMP GAS, that's just rediculous. But 1000-1300 rwhp on race gas are where most of the guys are at with GT47's, GT55's.

Supra's have about as much to do with this thread as the price of tea in China. Let me be more specific: Highest measured rear wheel horsepower, naturally aspirated, Ls series engine that runs on pump gas. I know the SAM 500 inch motor is badass and if it were in a car it would probably be on top. I know that dyno numbers don't amount to ****, but I just was curious. To all the people that replied to this thread with your results, thank you. From what I can tell the car that Mizfit built a few months ago and some of the LG cars seem to be in the lead. I have my reservations about some of the numbers of the latter though. I have no doubt that Lou's cars are badass and I am not saying he is dishonest. However it is just hard for me to believe that, that much power is coming from a "cam only" setup. However, it is hard for me to believe that the moon makes the tides rise and fall but it does.
