Some interesting info for WRX owners

GTBGUY · 03-20-2001, 10:35 PM

I just heard that the guys @ JC Sports have made a air-intake system for the new WRX's!

So for those looking for getting some more power "relatively" cheaply, something to look into. Definately gives you more power vs. just a panel filter.

Awesome, let's see some dyno charts!

BADWRX · 03-20-2001, 11:13 PM

I hope so because I will be one of the first to buy one. That is step one to "MORE POWER"!!!

Keith · 03-21-2001, 01:00 AM

i have never heard anything good about JC sports though, last I heard they are still screwing ppl over in the turbo gb, this is fairly common from what I hear.
Although, it is nice that they have new toys, I wouldn't send them my money
Just a heads up

JC Sports? They're still around?

All I can say is, it had better have a cold air intake.

Leszek · 03-21-2001, 08:17 AM

I agree with Glenn, you definitively do not want your engine to get air from under the hood. The turbo heats that air fairly well and you will loose power if the intake is not a cold air one.

DeliciouSpeed · 03-21-2001, 08:26 AM

Not really, a block off plate would do well, but just plain open would still make more power. I would not do it though, you get more air more power, but it will be hot air=increased likely hood of detonation.
A true cold air intake is the way to go.

GTBGUY · 03-21-2001, 09:01 AM

I'll keep you guys posted when I hear more about it. It's suppose to be a CAI for the WRX.

Actually, JC Sports quality is really good, only they are lacking resources for customer service.

DLC · 03-21-2001, 09:08 AM

You must remember this one thing:

Intercooler.

The temperature of the intake BEFORE the turbo is insignificant to its temperature AFTER the turbo, there's is heated by compression and ambient temperatures.

If the Intercooler is working properly, it really makes almost no difference whether its cold-air or otherwise.

Point: Byron's EJ22T Impreza with 500+ hp has an underhood intake with a blocking plate.

BigElm · 03-21-2001, 10:13 AM

Isn't JC Sports banned to promote or sell on this board???
If this is true, just be careful GTBGUY!
Don't want to see you caught up in stupid messes like this...

Steve E · 03-21-2001, 01:50 PM

Here it is... looks pretty nice, as does most of their stuff. Too bad their customer service is "suffering". Looks good though, no price yet.

RidinLow · 03-21-2001, 01:51 PM

Haha, that's one funny looking intake

. It must be a PITA for whoever applies those JC SPORTS decals to their intakes, especially since a lot of people peel them right off when they get them

Youngun · 03-21-2001, 01:56 PM

Lets do a group buy!

RidinLow · 03-21-2001, 01:58 PM

Youngun, why would you want a WRX intake with your 2.5RS? Unless you're giving it to me?

This is not really true. You are violating basic laws of physics. The turbo heats air up +X amount and the intercooler cools air -Y amount true but the air you start with does make a difference call that Z.

SO:
Z+X-Y = final intake temp

If you lower Z and keep everything else the same You get a lower intake temp (dense air charge).

KC · 03-21-2001, 02:19 PM

Hmm that pic of the intake won't work with a WRX...

There's no place for the MAP/S/F to hook into.

HA,HA

Steve E · 03-21-2001, 03:07 PM

the MAF sensor is smaller and "modular" like the ones on the new Celica. That square boss welded onto the tube gets the sensor.

Concillian · 03-21-2001, 03:22 PM

Skid, this is not quite true.

The efficiency of a heat exchanger (intercooler) will go up as the tempurature difference is increased. So, as the temperature of the air being expelled from the turbo is increased, the intercooler will become more efficient, and the temp drop across if will be greater.

Depending on the system and how good the intercooler is to begin with, it's conceivable that there would be no difference in engine intake temp for a temperature increase at the filter.

In addition to this, the temperature gain of the intake is caused from the compression of the gas. The effect of the original intake temperature is going to be partially 'masked' by the effect of the gas compression.

So the way I see it, original intake pressure may have a small effect on the ultimate power of the engine (when the turbo is at full boost,) certainly less significantly than an N/A car. It will also be considerably less significant when at anything less than full boost, as the free breathing helping the turbo spool faster will be a bigger help.

Cold air is a bonus, but free breathing is the more important factor, I think.

GTBGUY · 03-22-2001, 12:11 AM

BigElm - thanks for the concern bud

IIRC, they are banned until the GB for the turbos are done.... at any rate, I don't work for them so it should be ok?
