(and yes, I know that HP is a derived number. . .but because HP=torque*rpm*5252, and since the 2-strokers can rev SO high, we can't really answer it unless we know some benchmark numbers. . .and I don't have a benchmark setup.)

aspiration is a seperate issue. I don't beleive supercargers are legal on the 2 strokes so, should not be on 4 strokes either.
As far as torque goes; if the 4 stroke guy doesn't have enough torque to translate into competitive speeds, that's his problem!
Let's throw them out there and see what happens!
Might as well start out with a ratio of-2.17:1 (to make it easy on the engine builders--what with them already making one that fits that ratio!).

These five gentleman worked tirelessly on the set of guidelines and Novak presented them to ROAR. This past October meeting, Novak and Reedy were in attendance to promote the guidelines - now with consideration to ALL brushless types.
as always...

I would love to.
I can't do it now, though - I have to go up to Seattle to watch some poor sap marry my sister. . .
I'll be back in a week (I'm taking a train, kind of an enforced time off from work, internet, everything. . .it's been a while).
Once I'm back - yeah, that would be cool. And I will check out that thread.
Yep, it's Jason I was thinking of. . .oops! Good thing I'm just SO good with name, ain't it? Sorry 'bout that.

Boomer, I wasn't insulting you dude, I wa joking that you dont trust a magazine but quoted Tower.
Check out the thread in the 4-stroke development thread and you'll see the dyno graphs with the 4-stroke. Better yet. Since you're local come to the office tonight and see our dyno in action. Brian and I have to dyno a couple of engines and you can see the pudding.
Email me and I'll tell you were the office is.
Ohh, I never worked at Pegasus you're thinking of Jason our photographer.
Stinky1 and Orange, you comments about magazines are typical racer comments who lose sight of the big picture. Not all cars are race cars and therefor cannot be judge like that.
I wonder what kind of real car you have...if it's not a Ferrari it's the biggest pile of crap there is.
I'd love to point out the things we said dont' work, but I'm not trying to convince you of anything. it seems your love for you ROAR has blinded you of other things...just like magazines ROAR needs some attention. Because everything that comes from a ROAR reps mouth is nothing but "good" and doesn't want to hear about change....but I won't get into that here

If I had the choice of a Ferrari and a new GT40......
I would take the GT40
If I had the choice of a Ferrari or a Corvette.....
I would take the Corvette
If I had the choice of a Ferrari or a '68 GT500KR Shelby Mustang
I would take the Mustang
If I had the choice of a Ferrari or a '74 Ford Pinto....
It's a toss-up. I hate European cars.

GT40--Yes!! agree with you there Orange!
Ferrari over everything else..close call on the vette though.
Mustangs are for GIRLS.
Pinto----hmm. Fill it full of LiPo's and a couple of big brushless motors! Might be fun.

The new vette is pretty damn cool! This coming from a Ford guy.
For girls?? Only convertible and notchback 65-68 models. You always see girls driving these.
Not the fast backs though.
The Pinto, Make sure you fill the gas tank and put 400 lbs of bottle rockets inside. Then drive into the back of it with a Chevy Blazer. Will make for a good show! BOOOM!

Boomer, Whenever you're ready to be amazed let me know. The dyno and it's software is nothing short of amazing. Although you've confused me with Jason I'll still let you come see. We've sold 10 dynos to manufacturers already

While many may think I am closed minded - I am actually very open minded if people can show me reality. . .

Can you take some pictures of the dyno? Just out of curiosity, how much would something like that cost?
