...or it runs very high rpms.

Big whooop! 105 hp per liter!!

There are 3.6 liter porsche motors making this right from the factory!

How do you know the displacement of this engine? What else do you know about it?

I don't know if they did more work to it, but I saw this car running at RA with this engine couple of years ago and they had a lots of problem and spent 95% of their time fixing it. I have a few pictures of the car.

One of my cars is 220 hp/L. What's your point? It gets harder to keep specific power output up as displacement increases. 700 hp naturally aspirated is very impressive.

They probably weren't using amsoil.

I was talking to the kelly moss guys when they were running at laguna. I think i remember them saying it was a 6.5 liter.

i know they did a lot of head work and had some radical cams. Then, when you put on these types of intake inlets, the HP goes way up.

Just think, nascar puts out 700+hp out using 4 little holes at the bottom of the carburetor!

The point is, there are a lot of cars with 120+ hp per liter. If you use some of these same techniques with a V8 using the same engine designs, yes it is harder, but you can get in the ball park. the e30 BMW engines my buddy makes, get over 250rwhp with a 2.5 liter with nothing really that special on it.
(modified yes, but still stockish) you start getting radical cams, individual TBs with big runners and you can get exactly where the kelly moss engine is with a little more than doubling the displacement., pretty easily.

This thing from Kelly Moss, one of the top race car builders, was like one of their science projects. I think it was pretty expected that it would be in the 700hp range.

what car do you have that has 220hp/liter????

My 1991 Audi 200 20v. It's a 2.3L I5 with a 4v head running a Garrett GT3076R turbo. Boost is currently around 27 psi and it spins to 8200 rpm. It's pretty much the inverse of my 928. My 200 starts making power where the 928 starts to fall off.

sounds a lot like the Mitsubishi Evo that we were competing against this past year.

440rwhp, with a 2.4 liter running 26lbs of boost.

However, i think we are talking N/A motors. LOTS of the turbo folk are doing thiis. (huge hp /liter ratios) im amazed to the strength and durability of some of the evo, audi and VW engines with this kind of engine performance. the VW World challenge racer i was running against in our laguna event, was 330rwhp out of a 1.8 liter and he had a little **** to kick it up to 360rwhp if he needed to

certainly 700hp is impressive, no matter what the displacement. I think the world challenge vipers are making near 550rwhp but its an 8.3 liter

711 crank hp is not that much higher than Louies motor....584whp is about 687 crank hp...& thats with a fully streetable engine with "only" an 11.3CR on street gas..... Even at louies lowest dyno run 564whp hes still at 663... So assuming the race motor is about 13.0 CR designed for race only gas...that would make about 5% more power than louies or about 720 crank HP..... & the Devek B1 cams he runs aren't full race cams either....

Call me an optimist but I think we will see a 600+whp NA stroker in 2008.... I'm guessing 610whp

mark kibort

Hopefully, ill be lugging around with 400rwhp with the Rennlist sponsored stroker. maybe it will last 6 years + too!

Some old (2003, I think, guessing this is at Road America?) pics of this beastie for those that haven't seen it.

Very cool!
