Forced induction into a 4cyl, or a 6cyl?

[qwesterra]

I have a mighty question that has been boiling in my system for quite a while. I have asked ConVict like I always do, but we couldnt figure this out.

Lets say you have 2 cars, one is a 4 cyl and one is a V-6, both of which are naturally aspired, and have equivelant horsepower. 200 lets say. ceterus paribus, I inject 6psi of air into the engine for all rpms, which engine will give me more power? The 4 cyl, must have higher compression then the V-6, but the 6 has 2 more cylinders. Would I get more power out of the 4cyl or the V-6?

Ya I'll just add somethings to this. The turbo is the same size running in both applications at the same PSI. Both motors are putting out the same hp rating because of the high compression in the 4cyl engine, and the relative low compression in the 6 cylinder engine.

yes, hence.. ceterus paribus.

You need an asian to explain it to a white guy what ceteris paribus means...

[ConVict]

I guess so

*sigh*

ceterus paribus is a term for "All else being equal"

looks like someone enjoys econ...

Not surprised....

6's weigh more. Even if all else is equal it's wayyyy to typical for a 6 to weigh more that it can not be tossed out as an equal. 6's generally make more torque, more easily as well. Picture a silvia engine inline turbo 4, and picture a skyline engine inline turbo 6. If anyone was ever given the choice of engines, the votes would all go for the skyline because it make more power, easier.


P.S. 90% of the time 6's exhaust tone sounds better two.

anyone know the weight of a VR6?

torque is more a factor of displacement and engine design then number of cyclinders. And since 99% of 6 cyclinders displace more the 4 cyclinders....

it makes more power cause it has more displacement and it the end of the day there is no replacement for displacement!

agreed!

For the Jetta:
GLS 2.0L 1,331 kg
1.9L TDI 1,365 kg
2.8L VR6 1,442 kg
1.8T 1,378 kg

I just want the engine weight?

WTF. I asked a simple question, huh? whats that? GTS Jeff knows all, but can answer the question. Dont run up here, saying stupid stuff like I get the shameful because I asked a question. Well? C'mon GTS answer it, this post got completely off topic here, can anyone answer it? Its a damn good question, and its more then worthy to put on this forum, if anything it seems a little too advanced. No diss to anyone, but GTS Jeff answer this one smarty.

I could be wrong here, but I'll take a stab at it.

I would think that the V-6 would get more power, especially if it's just the compression and the amount of cycles. Turbo's are the same size, but the V-6 does have the advantage...

I dunno, I'm tryin correct me if I'm wrong!

[jdmakkord]

I'd take an inline 6 over a v6

[redline]

There is so many factors in this. It is hard to give a simple answer.

the reason i did not answer your question is because of this:

thats right. i cant give a "good" answer to a "bad" question.

I don't think it's a bad question.

Not really, the answer is easy. 6 is better generally speaking.

oowww Jeff goes down
