Intercoolers

Post by **S14Zilvia** » Sat Feb 22, 2003 9:33 am

I'm about to possibly buy a very nice intercooler for my ka-t. It is 28inches long, over a foot tall, and 5 inches wide. I can get a pretty good deal on it. It's made by langerer and reich.

I've also been looking at the volvo 740 intercoolers on ebay, and they're going pretty cheap. They are very large, very thin, and have inlet in outlet in the perfect place for short piping.

Does anyone have any info on the volvo intercoolers, and how much difference is there between 1 ft. IC piping and 3 foot IC piping as far as performance loss?

It seems to be too wide, but it might fit. I got a Volvo I/c and it measures 33"x17"x2" or something close to that and it's WAY too wide. Take some measurements to make sure it fits. Some people say Volvo intercoolers are good, some say they're bad. They're Blackstone units, usually with plastic end-tanks if that says anything.

As far as IC piping, the shorter the better, but i don't think it would make that big of a difference. I guess it's more an issue of throttle response than anything else.

Well, I bought that intercooler.

I took some measurements before I bought it. Looks like the max width is around 28 inches. Height is not really a problem. The thickness of that core is going to force me to use an electric fan and move the radiator back a bit.

The angle of the endtanks might also be a problem.

I'm pretty happy with it considering I got it for $255. Looks like a beautiful intercooler, built in germany for 944's. I don't think I'll have any problems with not being able to flow enough air.

the volvo i/c will flow tons of air for you. the specs on it are:at 331cfm and 293°F on the inlet side of the IC, the pressure drop is 0.55psi. The outlet temp is 126°F, heat rejected is 58809 BTU/hr, and the calculated heat exchange area is 1539 square inches.keep the piping as short as possible. as length increases, so does the pressure drop. good luck fitting the volvo i/c w/ custon piping. did you figure out if it will fit? is it too wide, 5 inches sounds really thick.nick

?? Who are you talking to? I bought the 944 intercooler, the other guy already had the volvo. The langerer and reich one that I bought is 5 inches thick, and yes, I think I can make it fit.

sorry s14zilvia, the first two posts were about the volvo i/c and when you said i bought that one i just figured it was the volvo one and wanted to give you some specs on it. sorry for the confusion. i guess i misread your post. hope everything works out.nick

i just measured my mouth because i have an intercooler predicament too... its about 28 inches wide... so if the cores is that wide you might have a problem?

is 30 inches too wide? ^_^;; cuz thats what im looking at buying

Post by **S14Zilvia** » Sat Feb 22, 2003 9:33 am

The core on my new i/c is smaller than 28.

Supposedly from tip to tip the whole i/c with endtanks and mounts is 26 or so... I forget.

Post by **Maeda** » Sat Feb 22, 2003 9:33 am

that sounds small enough... seeing as apexi, trust, hks, use about 20 inch wide fmics....

oh i ended up getting a 19 inch core too =) so no more fitment problesm

Post by **detforme** » Sat Feb 22, 2003 9:33 am

i got a 24.5 x 11 x 3 pwr to fit. with endtanks its probably about 30". ill check tommorrow. trust me though it isnt easy. there's lots of cutting for fittment.

psst, you dont need a huge intercooler

on mr2s people use TINY top-mount intercoolers that see almost no airflow, and boost 15psi all day long.. the fact that 240sx's can use FMIC helps cool tons. overly large IC's will increase pressure drop. you should buy the smallest intercooler you safely use. theres a point where bigger = less power.

Post by **detforme** » Sat Feb 22, 2003 9:33 am

yeah to a point. but i dont think that i will encounter any problems. gtrs use pretty much the same size. also mr2's were designed for boost. therefore less prone to dentonation problems. also smaller intercoolers can expirience heat soak under hard conditions.

????? !!!!!

The bigger your IC is, the larger the "space" from your turbo to throttle body = means you need more air flow (cfm) to maintain your boost (psi).

The larger your IC, the cooler your air will be = means you can run more boost with lesser change of detonation. But also:The larger your IC means bigger surface area for air the flow though = creates higher viscous drag (commonly called frictional drag, which occurs at surfaces) = more pressure drop at end of IC.

The more boost you run, the higher heat the air will become. You need bigger intercooler to cool it down.

Is a cycle. But you shouldn't get "smallest intercooler".You should get a IC that is big enough that can hold your boost while efficiently keeping the boosted air cool.

Yeah, but Toyota knew they were going to be pushing in alot of hot air, so they mapped out the fuel accordingly. Correct me if I'm wrong, but don't MR2's use 440's stock. Thats a big injector for a 2 liter.

right, at this point im pushing 6.53lbs. of boost with a t3/60-1. it should be able to flow enough. correct me if im wrong.

Good luck getting that thing to fit, S14zilvia...keep us posted as to what you have to trim/remove to get 'er to fit. According to my measurements, the biggest I/C i can fit in a stock S14 bumper is 26x6x3...and that's with a little of the plastic bumper trimming...Where did you find such a deal on that ic anyway? I'm getting a brand new spearco 26x6x2.25 intercooler for $425 shipped, should be PLENTY big for 7 psi...

You are running a T4B 60-1 witha T3 turbine? How the hell are you dealing with the surge?

Post by **WDRacing** » Sat Feb 22, 2003 9:33 am

I was looking around, you can get the 60-1 in a TO4E compressor.

thanks i found it too, but with the 360 degree thrust bearing it was cheaper the way i did it.

Post by **detforme** » Sat Feb 22, 2003 9:33 am

hey wd you said you were an aircraft mechanic right?

Post by **C-Kwik** » Sat Feb 22, 2003 9:33 am

Where did you find that? Neither my Turbonetics or Garrett Catalog list it. The only turbo that is referred to as a 60-1 is considered to be a T04B compressor. Though it really shares no common dimensions with a T04B.

But if it does exist as a T04E in a 60-1 trim, I woul imagine if it's anything akin to what they did to the T04B, it would still require high airflow at low pressure ratios.

Post by **detforme** » Sat Feb 22, 2003 9:33 am

actually i found the t04e in a 60 trim, its a tough fit for mine. i used the revhard mani. i had to shim the master cylinder booster to fit it in.

Sorry its 62-1....I swear I saw a 60-1 somewhere. http://www.turbochargers.com/ under T3/TO4E

Post by **C-Kwik** » Sat Feb 22, 2003 9:33 am

The 62-1 is also considered part of the T04B compressor family.
