Why one huge turbo? Twin GT35r will make 1000whp. I like the 3.0l idea with titanium rods/pins and heads to rev to 10k... All realistic. Dry sump it so oil wont be an issue. I can see 50k in just the engine.

Why would anyone even consider a Subaru for that much power?

The only engines I know which can have that kind of redlines are 4A-GE's.
Well, I know for a fact that one member was running a stock EJ22T block to 10krpm. I was just mainly stating it that way because if he's going for horsepower, there ARE easier ways of getting the power then shoving a ton of boost into it. 1000hp at the stock RPM levels? That would take a LOT of doing, for sure.

I think 50k will be short. considering the guy is probably close to $10k just for EM and tranny for this setup, $40k for a motor and turbo setup for this power is really steep.

I have a hard time thinking of any Subie setup that would support this. H6 is probably on the right track, but can somebody get one to rev above 10k? Getting there WITH nitrous would be hard enough.

Here is a simple bolt on 1000hp upgrade:

A twin turbo SBC will make 1000whp pretty easily.

Well, I found out that Simon at PPG said that their 6 speed dogbox could eat 1000HP for breakfast and ask for seconds, so that solves that problem. Wether the rest of the driveline could hold or not is another question as no one has run that much HP through the aftermarket driveshaft, axles, etc. Thanks for the serious and funny ideas as this is more of a what if question than anything else.

I assumed a PPG 6-speed dogbox would do the trick. Even with a Unabomber discount , that's still around $6k. Assuming stock axles and driveshaft are good for that power (pretty hefty assumption), you're still going to break 10k for the em and clutch, right?

The good thing is since it's AWD, the axles don't need to be as strong as a 1000whp RWD car. The driveshaft may be too weak. You may need to get an ACPT, if their CF shaft is good for that power.

1000whp with nitrous is hard enough, but reasonably do-able. 1000whp is usable anyways unless you're going to run 1/4 mile runs, and if that's the case, just do a fully built, stroked ej22t w/ nitrous and you'll get there within budget and reason.

$50,000 that might just be enough for engine / swap / internals / turbo/compatiba;ity/ correct specs/ and Labor.....

...Labor is a killer...

I guess the customer specifically does NOT want a roll cage, so drag racing is out. I assume this will just be a dyno queen. And remember kiddies, this is a theory question more than anything as I have no hand in the the sale, just starting some discussion on what it would take. Personally, I'm inclined to think it would take more money, but the potential buyer has already talked to another Subaru shop that said they could get him 1000 WHP for $40,000. I'm thinking on that.

True, but don't forget your drivetrain losses! I hate to be a stickler, but I have to admit that I'd sure love to have a 2.7% sap instead of ~30%!

Complex has the right idea though, I think. You can avoid a lot of costs and development stuff by moving the hp way, way over to the right on the plot. it's the torque that breaks stuff.
We all know that there are a couple vendors here who offer 8500rpm units from the 2.5.
What if you destroked the 3.0L and went after the rpms?

Some very interesting info in this thread:
http://forums.nasioc.com/forums/show....php?t=1038296

Here's a couple key points:

"This is a stock H6 motor except for the addition of Supertec Forged H6 8:1 CR pistons. The stock valve train components are a very limiting factor in pushing the motor, so this initial tune is just to help develop maps."

"Given the valve train limitations (the exhaust valve springs are only 15 lbs), I didnít want to push the boost up above 14psi. I started at about 8psi, which quickly netted about 330whp. Upping to 10psi netteted 370whp, and 12psi over 400whp. At about 13psi, I was able to get ~420whp and about ~400 ft-lbf torque. I was very happy to get 400whp at only 12psi on pump 92 octane without the motor even breaking a sweat. At this low boost level, I could run AFRs anywhere from 11.1 to 12.5:1 without knock. "

"Here you can see the injector duty cycle, boost, and knock levels. With a peak injector duty of about 55%, 100% duty would be in the theoretical 730-750whp range. " <<Now throw in alk injection and you could be getting in the ball park, no?

A shop said that? I'm thinking they mean $40k in parts, labor NOT included

^ very true but look at it this way. The shop that builds the 1000hp subbie think of all the attention they would get and media from everyone on nasioc would be at there website in a minute. Thus bringing in more traffic for them so they dont have to charge labor on this one build if they know it will reap some HUGE benefits.

This reminds me of the early 80ís when Formula One was running exotic turbo configurations with exotic fuels to get some silly horsepower figures.

I just think the tweaking for an engine like this is going to be a nightmare, especially if you've only got one engine/transmission to play with. Itíll get damaged more than once before you hit 1000 hp. Cost over runs for something like this are going to be immense, given a $50,000 budget. 650-750 hp is probably more realistic. I fear the last 250 hp may be pushing it to far, without a Nitrous setup.

Look at the engineering issues the engineers working on the mighty Bugatti Veyron had to overcome, cooling etc.

To some extent, but the problem with demo cars is it takes installer's time away from current customer jobs, and you hope to get more business from the work to more than compensate for the lost time/labor. Most shops that spend a ton of time on demo cars later regret doing the job. Especially with a lofty goal like 1000whp without nitrous, which may never be achieved.

As far as cooling goes....run it on alcohol....just the drag guys do. No cooling needed.
