The large turbos your referring to don't spool on smaller discplacement engines (ie 3L supras) with the motor he's planning you'd have to think in context, say like 4 supra motors. Those turbos you think are large would be small for such a huge motor. They would spool up off idle and make it totally undriveable. It would be hard to find any 2 turbos large enough to keep that thing from quickly building boost, maybe like some 100mm turbos. :crazy:

This might help a little in the traction department:

Those nice wastegate controllers are wicked for street driving some are extremily nice to tinker around with some can be set on tons of diff variables.... rpm, mph, time and i think some others can be set using the tps. I am just using a innovative msbc :D and dont want nothing where merlin is thinking of going :crazy:
my goals are small but cant wait to see if this combo goes through huge cubes and turbos ummmm good stuff. (might also want to question on the nsca board to see what they have to say on turbo size :) i know there is a few that have run big cube motors with turbos.

Merlin, you asked if you could use an 8000 rpm engine with 1500 horses on the street. Not likely.

What I mean is, you'll find that you can get anywhere in the blink of an eye, with the warp engines still on warp 1 (1st gear). I think it's gonna be frustrating. At least in the traffic around Denver. It seems to be my curse to get stuck behind either a Saturn or a Subaru that is hellbent on going 10 under the speed limit for that extra mile per gallon. And there I am, in a 500 horse Firebird, trying to see how quickly I can kill an extra gallon.

Guys like us need autobahns. And SUV's, Saturns, and Subaru's would not be allowed. You'd have to be able to prove you have a power to weight ratio of better than 8 lbs/hp or something.

Besides, I have trouble with the concept of smoking the rear rubber when you drop the hammer at 120, and going sideways until 150. That should be more fun than a ride in an F-16.

But nope...you'll jump on it in 1st, and scare the pee out of a Subaru Outback driver when you haul it down from 140 mph to his 45 mph merging "speed". You might have to almost move to Montana or Nevada, where the highways are usually wide open.

:cool: :smash: :crazy:

Wow, this amazes me. My motor in my GT-1 (ex Trans-AM)car does about 650HP at 7500 out of 358 CID with a single carb. I rebuild it (springs, mainly) about every 1000 race miles. Even with hot road race slicks, I still cannot floor it out of some corners. A 1200 HP or more on the street is incredible! Good luck, be safe!

I'm with merlin the more HP the better. As far as traction problems, they get worked out. Here's my 800HP+250 from the bottle C4 :reddevil

You got my vote. Your c4 is a work of art. :cool:

Definitely cool. That twin plenum manifold is trick!

I can vouch for Torque. I was at there shop about six years ago. Sold them some CAD software. Man, those engines are huge!!!! They are designed to replace twin and tripple big-block marine installs. I know when I was there they were having issues with there engine dyno keeping up with the HP. I am sure they have a bigger dyno now!

Just noticed that those things are 860CI!! Amazing - this tells me it can easily be done. Also just noticed that they are publicly traded: http://stevenkamis.com/Stocks/detail...any=0001018675 Unfortunately their stock is at .0001 - a quick glance at the financials tells me that they are toast. Bummer. I found a quote on their site that very well sums up my feelings about engine building:

"There is no substitute for cubic inches.
Many years of successful manufacturing of high performance marine engines have given the company the experience that allows us to make the statement "that a fundamentally smaller block, no matter how radically modified, will always be overstressed and inadequate for long term production of high torque".

compuvette

Man, that sux! Didn't know the company was almost out. Anyway, the engines do look awesome! Very impressive in person. Heard one run on the dyno when I was there and it tached out a 1000HP dyno! Yea, baby!! And that was without NOS, supercharging, or turbo! Just cubic inches!!!!!!
