500 HP SVX at Subaru Training Center?

I would consider the following 'signs' of being an ignorant person.

1. The inability to spell or use coherent sentences.

2. Posting "There is no doubt in my mind that subaru can produce 500hp out of a 3.3 liter engine without forced induction" right after we had all discussed the theory of MEP and how it applies to our engine, and why getting 500hp out of 3.3 liters is next to impossible.

3. Claiming your stock SVX runs 14s when it isn't even timed right.

Heres where you show your lack of attention.

1. Quality dynamic writing skill does not represent inability to use coherent grammar.

2. key word "theory"

3. I never claimed it ran that fast while out of time. NEVER. I stand to my word that on a good day (and this was proven on tape) that my svx runs faster than my friends 15.4 Spec-V.

However, we dont have to worry about that anymore because I am coming under possession of a non R/T Dodge Stealth with customized turbo system that runs 14.2, proven.
This will be my new strip runner for at least a while.

Also, what exactly do you consider a "bolt-on" mod, of which you say I have "none" of?

EDIT:
whoops ma bad yo. the stealth isnt turboed, im talking to the guy right now.
the conversion wasnt completed he says. but it still runs 14.2.
>:P

specs - 6 spd manual, 4.6L V-6, rwd, beautiful
these along with 3000GTs are extremely common up here believe it or not.

EDIT2:
before i get burned on this i called edgo on the engine size after looking up stealth specs. he says the engine has been swapped with some gm motor.

I have said before, and I will say again... MEP is a very limited tool for measuring engine output, and it is extremely limited in terms of what can be said about ultimate torque or horsepower output.

MEP measures cylinder pressure as if combustion were a split second, instantaneous event, which it is not. Real engines in the real world are NOT governed by the MEP principle, they are only measured by it.

Based on the MEP principle, my friend Scott's 125cc shifter cart should only be able to produce *at maximum* 42.5hp. Unfortunately for the MEP principle, they turn out about 58hp at the rear wheels.

Combustion is not an instantaneous event, it happens over a far longer period of time than MEP accounts for, and exerts far greater overall force on the piston through its stroke than such limited theory allows for.

It is still a useful tool for sniffing BS, and estimating things. Getting 500hp out of a 3.3 liter NA h6 is damned impossible. Period. And just for fun, I'm going to sic Fyr4ce on you tonight Porter.

I never said 500hp out of a NA 3.3L motor was possible either. I also refuse to state that it is impossible.

Using MEP to "prove" your theory of impossibility is pretty shaky. I mean come on, there are drag boat motors that make 5000hp out of 6 liters. Granted, they are supercharged... but boost doesn't overcome the laws of physics or of thermodynamics.

Whether your point is ultimately valid or not is irrelevant at this point... you're using reasoning that is questionable at best.

But forced induction screws the MEP theory all up; its only applicable to NA engines. Sure, with forced induction or nitrous, theoretically, you can make as much power as you want. I could make 500hp out of one cylinder if it could take a billion lbs of boost and flow enough air. This whole thread revolved around the idea of 'naturally aspirated'.

PS: WHen are you going to autocross your car? I want to see your SVX woop some STis and start writing you a check!

Haha, I already autocrossed it once! I wasn't competitive in the class because of a bunch of tweaks to setup I was trying to make at the same time, but I placed pretty well considering. I was only a half second off the pace. There's still some classing issues to work out, I would have won DSP had I been running in the correct class.

You can write me a check pretty soon... the last pieces are falling into place this week hopefully.

The Ducati Super bike was 999cc twin, put out about 140hp. They decided to go GP racing, so they built a 999cc V four, rev it to 16k, for a 220hp out put. They fire two cylinders together to give huge drive out of corners. They have had great success for the first year out.

The point is that, if you can maintain the cylinder filling at higher rpm, the hp will increase in proportion. To increase the hp move the torque up the rev range. It can be done.

that's all fine and dandy, but who hear thinks 10 thousand RPM or more is capable in an h6? I don't. Actually, yeah, its PROBABLY capable, if the government wanted to build some unobtanium valvesprings and whatnot, but let me rephrase that question: Do you think subaru would have spent the sum of a medium sized country on an SVX engine and not sell any of the parts and hide its existence? No. They wouldn't.

Hang on Rob, I am not saying to rev it that hard . Max torque is put out at 4500 rpm now. If that was raised to 5500 rpm the hp would rise. Ask Fryce.

With a mep of 14.5 (which is really really really really really good),

500hp / ( 3.3 liters * X) = 14.5

500= 14.5( 3.3x)

500/14.5= 3.3x

x= It would need to make the power at over 10k rpms.

I take your point Rob, I was not aiming for the impossible just the possible. Yes 500hp would be at very high rpms. I would but the use able limit with the standard rods etc. At about 7500 sustainable rpms.
