If you compare the output of engines at a fixed rpm, for example 2000 rpm, then whichever engine makes more torque at that rpm will also produce more power at that rpm. A car like the S2000 produces more power at high revs than other cars because it produces more torque at those elevated revs.

yep, 901 transmission....Kennedy Engineering adapter plate and flywheel (9"/228mm version).....just ordered the parts today from High Performance House (re-seller) (a little over $500...ouch)

the location of the radiator is still up in the air.....once I get the /4 motor running better (I just bought 4 brand new 2.0 injectors for it, ouch again) I plan on running a few experiments to see how well the radiator in the rear trunk would work....worse case would be that I'd have to relocate it to the front trunk if it didn't work out too well.........

Dumb question: Kennedy Engineering makes an adapter plate and flywheel specifically to mate the 901 tranny to a VR6 motor?

Mike, from everyone i've ever talked to, the front trunk is the inevitable. A friend of mine who owns a 914 which races with the POC (his driver had the highest donation at this years Make-A-Wish foundation event at Laguna Seca) had 3 oil coolers at one point in the rear trunk, and still bad cooling.

I'm convince that without ungodly looking air scoops that rise above the hood line, the best, easiest place for any cooler is up front. If i had to add a cooler to my 914, i would make a cool looking intake below the front bumper, and put the outlet on the hood like a F50 Ferrari or Lotis Elise, i think that looks awesome, and not many people have done with the 914.

BigD9146gt,

how did your buddy do the venting of the exhaust air?

I was thinking of taking the intake air from vents in the rear trunk lid (picture) and vent the hot air thru holes (large) in the trunk floor...the rear valance might have to be taken off so that the hot air does not get trapped underneath....of course puller type fans would have to be mounted on the bottom of the fan

This is going to be cool and maybe even less expensive than building 150 hp Type IV motor!

The venting was out of the rear, between the tail lights, and air comming up from trans. It was a clean system, but destine to fail in my opinion because your working with a hot engine and trans, trying to cool fluid comming from the same location. If you made a farring inderneath the engine/trans like the new Carrera GT, then you should have no trubble making naca ducts or luvers to pull/suck air to where you want it.

The beauty of the water cooled engine is that you can close off almost every air gap, leaving simple air ways to cool what you want. I;ve thought about diong these things to my aircooled car, but have felt shy because of the need for air tumbling under the engine (those two rubber flaps bolted to the bottom of the chassis, most likely in need for the fuel pump, but probably help the overall cooling of the bottom of the engine too).

The coolest ducting i've seen so far was a guy with a turbo'd 914, be mounted his innercooler in the trunk at a 45 deg angle slanting back. He ducted the air in by cutting out the center of his rear trunk and sculpting it downward, then the exhausting air went out between the rear tail lights and a big hole cut in the bumper. I'll try to find a pic of it, it was at the German A-Fest a few years back...


....carefull what you say, fellow hardon-TIV builders could be reading.

what about a radiator setup like this guy has?
Right Here

The radiator is mounted face down on a screen with an electric fan on the back of it. he has no intake on the front, and appears to have no porting for the air sucked in by the fan to go back out.

I think it would work without problems, but i dont think i would put the spare cover over the raiator, at least not without some sort of supports.

Also, is it necessarily better to run the hoses inside the car as opposed to underneath like this guy did? For some reason having the hoses routed under the car doesnt sound/look very safe. I would think you could burn your motor up pretty quick if you hit something and sprung a leak in a coolant line...

My initial thinking about where to mount the radiator is to look at where they were located in the X19 and Fiero and maybe even the Ferrari 328.

not too familiar with fieros, do you have a link to a picture of the location?

I have my lines run under the car. They are 3/4" steel pipe formed to fit in the indentations. Even if I scraped them they wont break through.

sweet. i was thinking running lines through the indentations with possible fitting a kind of skid plate over them would be good, just for extra protection

I think that the Fiero, first generation Toyota MR2 and Fiat X19 all had the radiators right at the front of the car.

For a good reason.

I'm going to put my radiator in the front trunk and then graft a WRX scoop onto the front trunk lid. :)

Alfred, make sure you get the STi WRX scoop, it extra big supa fast!

i was trying to think of a way to vent the exhaust out the bottom of the front trunk. if you made a scoop on the bottom of the bumper and made a housing to channel it to the radiator and then put another housing on the other side to funnel the air down through the bottom of the floor. i know this would cause some turbulance under the car, but do you think it would be enough to affect the car?

trying to figure out the best way to do all this with the least exterior modifications possible... its all about having a sleeper...

also, for a front air scoop, wouldnt it be fairly simple to fab a whole new bottom section out of some fairly thin aluminum, such as air conditioning ducting metal? I have a bunch of that stuff lying around and every time i look at it, i think of ways to make it work

Poo, if your wishing to take the car above 90 mph, i would put money on the fact that venting air down under the car would create more upward lift.

I'm tempted to make one like the Mercedes CLK race cars and duct the air out behind the front wheels. Just make a box out of your sheet metal about 1 inch thick. I'll search for a pic of the mercedes, but this might give you an idea.

Umm, BigD... Have you ever noticed what your left foot rests on when you're driving? That's the left-front wheel well--right where you have your left-side air flow in your picture. You'll run into some interesting problems trying to duct the air that way.

As much as I dislike the look, I'm thinking that Renegade's setup (cutting out part of the inner fender) may be the better way to go. Maybe with a brace of some kind over the opening, just in case?
