i herd that u can get more hp from a quad TB than a turbo or the same and that it is cheaper so y dont thay make one for the lancer yet also anyone know y it makes mor hp ore the same hp
mainly i just love the way it looks

 

they do make one...RPW...use the search function, it's easier than typing

 

they do make one for the lancer you can find it on the rpw and vision imports websites, it doesn't just make a ton of power by itself, you have to get other parts to go with it like a cam and header and other stuff or it won't help that much, also it takes a lot of tuning to get it to work well wich means expensive dyno time, also it MIGHT be able to make as much power as the base turbo but you can get more power with the turbo if you do some other stuff to make the engine hold more boost, but the quads don't have turbo lag so it is give and take, it would be really cool if someone sold it with a computer that was easier to set up

 

i herd that thay have a bad a$$ sound too

 

I suggest contacting RPW. They'll be able to give you the lowdown on the quad, or just run a search. We already had a nice thread about the quad throttle body not too long ago.

Summarizing, it costs about $1000 for the quad throttle body and another $1000 for the computer management. Then you're gonna need at least a stage 2 camshaft and other internal mods. It's not quite a bolt-on mod.

 

quads sound cool if you have 4 air intakes, not sure where you would put all those air filter cones, but yeah its supposed to sound really cool if you do that

 

Correct me if I'm wrong, but I think the quad throttle body gives each cylinder it's own individual throttle body instead of having just one throttle body feed to each. I think you still only have one intake bringing the air in, it's just that it doesn't get bottlenecked at the single throttle body.

 

Quads are NOT more powerful than a turbo.. NA setups have their limits. They give great power, just like turbo's, eat gas just like turbo's, are capable of giving a 100% increase in power with the right modifications. A turbo can do the same.

But the two split in one field:
NA has it's limits on power increase.
Sky is the limit for a turbo.

Turbo's power is harder to harness, but it works when it's done right. In either situation, LSD would be required, and much internal work.

And yes, the Quad TB works in a way so that each cyclinder practically has it's own intake... At least that's what I've read.

Yes, but what about a beautiful harmonization of the two? Quad throttle body plus forced induction! RPW mentioned that it will be compatible, albeit the cost of outfitting the engine not only to house everything but more importantly to HANDLE everything, now that's the limit.

 

Guys, either way you go, it's going to be hard. Both require copious amounts of cash and careful tuning time to optimize your A/F ratio. Even mentioning the quads AND a turbo is borderline obscene just due to the sheer fact of the logistics. Quads like high compression, turbos do not. That's problem number 1. Where would you draw the line on a block with stock compression of 9.5/1. The computer needed, something like a Haltech or GEMS, would cost as much as the setup itself, and again, the dyno time. As for gains, boost is roughly equivalent to for every 1 PSI, you'll net 10 HP. This talk about the quads giving you huge gains (like what, 50%?), is all dependent on the facilitation of higher compression pistons (which in turn would require higher strength conrods) where then you'd need better valve springs to cope with that and then a more aggressive cam profile to even things out. Same goes for turbo save for less compression and the use of a turbo cam (holds the exhaust valves open longer). Don't just think you're going to be slapping on either one of these monster mods because it ain't happening. To do either of these mods the correct way, opening up the block is inevitable. We have WAY to many threads like these. Read up.

 

I was just sarcastically and wishfully quoting RPW on the fact that turbocharging + quad throttle body is possible. Lord knows how much "other" work has to be done, just like you mentioned.

 

qhost, you can use a single intake for all 4 throttle bodies or you can use a seperate filter for each one, not sure eactly how you would really do this but it should sound awesome if you could because you would hear each piston as it drew in air.

pjal, you don't have to have high comp. pistons to get big gains with quads, with intake, exhaust and a very agressive like stage 3 cam you would probably get a pretty big diffrence with quads, but yeah if your gonna do all of that might as well spend the extra on pistons before you spend the money to tune it on a dyno.

 

Qauds + Turbo can be done and work extermely well but we have to manfaacture teh qauds different to cope with boost versus vacuem.

To give an example i know of several race car teams, Audi, BMW (Which is now very pro multiple throttle bodies on a lot of there cars now) etc where they regularly produce over 200kw from 2.0 multi valve engines.

They potential is there, it comes down to slowly working yoru way through the system.

pjal said it... The compression ratios are key.. I can't imagine how an engine would be able to benefit magnificently from both Quads and a Turbo, maybe with a compression of 9 or so, it could run 6psi, and a Quad, I dunno. Just seems unreasonable. And the engine management system, blah blah blah, pjal, bahamut, mobius and all of the monkeys including myself have discussed this before in other threads that seem to have hidden themselves somewhere.

Just the $ needed and the time needed as well as the work, Jesus, it just seems a little... what's the word.. "over the top".. Unless it's a full blown race car, screw it. This car's my daily driver.. And turbo sounds good for myself..

quads are nice. very expensive though. and the driveability of ur car goes down significantly. with all that extra air ur getting to each cylinder, ur gonna have to add in fuel too. fuel economy of ur car will drop...alot.

but yea good thing is that u can use it with a turbo or a blower if it is designed the right way. so thats a plus.
