Looking for some help on my car

[kcklla]

I have a '94 honda prelude and I am looking to put a supercharger on it. I want to get some advice from some people that have used superchargers and what they think of them and the brand they went with. I am also looking to put a cold air intake system and a new exhaust system. So any help on this would be greatful.

wow, you must have some cash burning a hole in your pocket!

I do, I have been putting a little away every week for about a year waiting for this time.

a turbo will net you better results on a prelude.
But seeing as how it's a front weel drive car, you'll prob be better off just replacing the headers, cat-back exhaust, new pulleys, and a lighter fly wheel.

By going turbo or supercharger, you can only do so much on a stock engine. if you go higher than about a bar of PSI you'll want to get lower compression pistons. IMHO a tubro is the last thing to do to an engine. Tune it properly, get it's max potential from N/A tuning, then if that's not enough get the turbo.

Save it for something more important

1) A Honda prelude doesn't have "headers". It's an inline 4, at best, it has a single header.

2) You don't put a cold air intake and a supercharger on the same car. Because: 1) a CAI doesn't do anything for performance, and 2) A supercharger kit will come with it's own intake equipment. Even if it didn't, a standard CAI wouldn't fit with a blower on there.


The supercharger on my car is no longer made, so I'm not going to recommend it to you. I've seen supercharged hondas by both Jackson Racing and Vortech, and the Jackson Racing car was performing better.

I know a bit about supercharging, after doing it to my car, but not that much about Hondas.

He's completely right on this. Because a supercharger (or a turbocharger) compresses the air, it also heats the air as a by-product of the compression. Unless your CAI is dropping the intake temperature by 60-100 degrees F, any potential benefit will be completely overcome by the heat induced by the super/turbocharger's compression. What you need with a super/turbocharger is an intercooler, which cools down the compressed air after it has been through the super/turbocharger. A good intercooler can drop incoming air temps by 100+ degrees F.

header, headers samething, just the s is plural. sorry grammer police, CAI will do something for performance, hence why it's called a COLD air intake, colder air is better(true that it won't do squat for a supercharger). look at dyno sheets and they'll show a messured performance gain, it's not much, but on average you can expect a 2-6hp gain to the wheels, and about the same for torque.

I didn't know about that. 'Cause a lot of Maxima guys put a CAI for their Vortech blower and have noticed slight gains.

this is why if you are pushing a certain amount of boost or more, a intercooler is required, cause something spinning about 150,000rpms get's really hot.

If you put an intake pipe specifically designed for the blower on there, yes yo might get a slight performance boost, but what I mean is that you're not going to go down to pep boys and buya CAI for a '94 Prelude and use it on a blower car.

And I'd LOVE to see the dyno sheets showing 6hp at the wheels from just a CAI on a FWD 4 banger.

You know that 6hp is next to nothing right?

150,000RPM? You do realize how incredibly fast that is, right? That's 2500 revolutions per second... I don't think that's possible. It isn't the spinning supercharger that heats the air, it's the fact that the air is being compressed.. which creates heat. That's why you can't run low octane fuel in a high compression engine, because it compresses the fuel/air so much that it can spontaneously ignite.

Get a turbo. I think Greddy has a kit but I might be mistaken. A high-revving H22 needs a turbo, not a supercharger. The Jackson unit is good but 75% of Honda guys, like myself, will tell you a turbo is the only way to fly. Uhm, as far as the amount of boost, the guy who said 1 bar is way off. The most you'll want to throw into it is 6-7 psi. That motor has a 10:1 compression ratio. That's too high for any sort of high-pressure setup w/o changing pistons/rods.

All I can say is find yourself a good mechanic/builder to do this or you will have problems.

 

[kcklla]

well thanks for all the advice, I will look into an intercooler and upgrading other things first.

hehe...the QR25DE (2.5L 4-cyl in the Sentra SE-R) actually gained 6+fwhp with a CAI (I think..I remember reading that a long time ago). But then that engine was extremely restricted from the factory. There are dyno sheets proving this too.

But I do get your point, usuallly things like intakes don't really increase the power that much. Forced induction or serious engine mods are needed.

 

[bUnMaNGo]

also try the forced induction forum over at honda-tech

 

[rubenswm]

i was just gonna tell him his best bet would be to try honda-tech.com or honda-acura.net

150k rpm is too high, but superchargers do run 45-60k rpm.

Street turbos will spin their vanes at about 100,000 RPM. Racing turbos will spin around 150,000 rpm. (Both at WOT.) Of course, that's just the impellor vanes and not the actual compressor, but still.

ZV

EDIT: Testing has shown that an engine needs between a 10% and 15% increase in power before there is any measureable difference, so unless the stock engine is making 60 hp or less, a 6hp gain will be undetectable. except by a dyno. You'd need at least 20 more hp on that Prelude to notice anything.

 

[LAUST]

I think the only real option for you as far as SC is a Jackson Racing Roots style, or like people have said go with a Turbo.

I would not do either on that car really unless you know what you are getting into and can do your own work. Forced Induction can be a lot of work on certain types of cars, a 4 banger Honda I would say is one of those.

actually hondas love cai.. im too lazy (actually my internet is being retarded right now) to look but ive seen a dyno for a stock rsx-s gain 15+whp with just a cai.

it's not that a fwd 4 banger cant gain 6hp from a cai because its a fwd 4 banger, it guess it just depends on how much honda detuned it before shipping it.

imo anyway.

i dont like the car but i just felt is hould point that out
