Celica Forums General Discussion Exterior 50 hp exhaust?

I got into a convo with a guy in my hall way the other day and he was saying something about some exhaust that adds 50 hp to any car?? he said that it had a blower on it so it actually sucked the exhaust out? cant remember what he said it was. i was just wondering if i had to put some boots on because of all the shit he was giving me or if he actually knows what the hell hes talkin about. tell me if any of you have heard of this before.

you can't get 50hp by bolting on an exhaust. You can't even get 50hp with a supercharge.

DAMN!

I'm gonna go strap my vacuum onto my exhaust tomorrow.

No its not possible, end of discussion.

he is talking about the new apexi exhaust but it doesn't give you 50 hp

anyone talking about an exhaust sucking and giving 50hp. I'd say: yo'momma.

yea you can

Not with the celica but with many other cars you can.

ask him where we can get this exhaust?! and if i put two of them, is it gonna give me 100HP???

our team mate dynoed 150ish stock, and now hes dynoing 215 to the wheels with the trial/bliz supercharger on his gts

thats more than 50 whp

sucking the gas out of the exhaust would be bad, because you would suck the fresh Intake charge right out at higher rpms where theres more valve overlap.

I think you get the idea - that amount of hp is ludicrous from just an exhaust... no matter what kind of esoteric things are going on inside it

no, you can't get 50hp, you can however get 200hp w/a park bench wing...50hp??? liar...

i dont wanna say no. all i wanna ask is wut kinda car does ur friend drive?

no

simply put

no

fuckin ricers

...kill him...

wow

Kinda like some dude at my high school who says hes gonna get 50+ hp from his new jet chip that hes gonna put in his Auto Grand Prix GTP.

NO

ya thats the only thing sucking...must b a ricer because i had one come up to me and said his Intake gives him 30hp i was like right...his proof> a game he played

look at it this way:

with ONLY an exhaust (everything else remaining stock) you CANNOT go over your cars bhp.

bhp is your cars horsepower at the FLYWHEEL, which is basically how much power your engine produces.

whp is your cars horsepoer at the WHEELS (what your engine actually produces with a tranny, exhaust, etc and friction is minused from bhp.

thererfore, all an exhaust really does is reduce friction (allow more air to exit more freely). therefore, you cannot go over your bhp by just adding an exhaust--because it isnt actually adding power to your engine--it's just allowing your engine to run more efficiently.

(celicas gts usually dyno at around 160 whp. the bhp rating for a gts is 180 bhp. 160 whp + an extra 50 whp = 110 whp. obviously this is not possible.

it's an interesting idea though about an exhaust sucking out air through a reverselike blower. but the bottom line is still that it's not ADDING bhp--so it can't go over 180 in a gts. and obviously an exhaust isn't the only thing restricting your engine so even with no friction from the exhaust you still can't reach the bhp rating of your engine.

sucking the exhaust gas out would be bad, there is such a thing as too much scavanging effect. This will cause the fresh Intake charge comming in to get sucked out by the pressure difference in the exhaust, at higher rpms during valve overlap. This is a bad thing as you need the fresh Intake charge to produce power.

You have to find the fine line where most of the exhaust is sucked out, and not spit into the Intake charge, and where the Intake charge isn't being sucked out into the exhaust.

not true man

^^^^ (response to illusive).

good point. you would have to find that 'right spot'

lots of graphics and altezzas wil fo sho get you at least 60
