question about intercooling

[nightkid86]

About this 'snow packing' on the intercooler, be careful. I was watching WRC last year and a car hit a snow bank and got the grill packed with snow that froze infront of the intercooler and insulated the intercooler, thus making it warm up more - and robbing the car of power and making it overheat or something bad. Ice can insulate, thats what igloos do. That's also why its hard to freeze an entire lake - the top layer of water freezes first and insulates the rest of the water.

Yea, thats basically the conclusion we've come to. Like I was saying, its not a bad idea to cool the IC or intake manifold of a car down between runs at the strip with bags or ice or n2o or whatever. But, snow just wouldn't do much. And, yea, the IC actually cools by having air moving through it. So, having something blocking it, even if its cold, wouldn't really help. And, even then, like I was saying as well, the ammount that it cools would be so insignificant it wouldn't be worth it.

Top mount?

This a picture that most accurately represents my engine bay. Acutally, this is exactly what my engine looks like only its full not nearly as clean...The black thing at the top of the picture is the intercooler. Is that what you mean by "top mount"???

if im not mistaking that is not an intercooler that looks like a ram air intake box
that feeds off a hood scoop

Nope, that is how the Ford 2.3 turbo intercoolers look--the airbox is located near the wheelwell toward the front of the car. The turbo sit more or less below the intercooler.

Yes, it's very possible unless you used some really extreme setup.

Speaking of really extreme setups, anyone care to comment on this? Yes, it is real. Even with a modded V8 it would still have some hellacious lag being that far back. Oh well, it would still probably kick ass - regular LT1 low end, with some crazy turbo'ed LT1 mid-top end. I couldn't leave it parked out anywhere in public, though, without fear of someone just walking up, and unbolting my turbo. Also, you couldn't drive it in the rain, or over any speedbumps. And, have any of you heard of "barrel" intercoolers? They don't look like your traditional FMIC, or TMIC's.

That rear mounted turbo setup is for real. I forget the company that makes it but they had a pair of turboed Camaros for people to drive at a car show in the Twin Cities last summer. One of them had their old front mounted turbo and one of them had their new rear mounted turbo and there was no notice-able difference between the two cars. I think the rear mount is smart, it gets the heat generated by the turbo out of the engine compartment as well as keeping the headers cooler. It also lets the exhast gas cool before getting to the turbo letting the turbo run cooler and save the oil from coking. Piping the air back to the front acks like an intercooler.

I also like the fact that the first time I looked under the hood of the rear turboed Camaro it just looked like it had a cold air intake, can you say sleeper?

And that pic is from a camaro?...You've gott o be kidding me..With that tiny ass single piped exhaust, and such a small turbo...are you sure that's a V8?

3 inch isn't that big guy.....3 Inch piping is very common on DSM's and other 4cyl T/A car's..
And I doubt that's even three inch
That's a V6..That has to be a V6..There's no way a LS1 or LT1 could survive with THAT much backpressure from 1..such a small exhaust system...And 2, the seam on the piping that contacts the exhaust housing

Yes it is from a Camaro, with an LS1. And a single 3" pipe is plenty for a 350 and as for backpressure the turbo would produce more then the pipe.

the more i look at that picture the more i think its a load of bollocks. what is the turbo connected to? the rear diff???

if it does work im sure the owner doesn't get any extra power from it, its just for show.

As for how it is mounted to the car. The turbo assembly is bolted from the stock muffler mounting brackets.

And the performance gain is similar to that of a single under hood turbo.

A little more info, the kit is make by Squires Turbo Systems, http://ststurbo.com/ . They also make LT1 kits.

Here is a dyno chart so you can get an idea of the performace gains.

thank you skip0110...

This is accurate. Thanks for the backup skip... I know my own car!

Also, I am aware that the intercooler needs air to flow through it in order to operate (hence the hood scoops on my car). I never intended to "pack the IC full of snow". I just wanted to know if a cube or 2 of ice (which won't fall off due to the fact that the IC is recessed and the hood scoops stop it from falling off) or a tiny amount of snow would be enough to gain an extra hp or 2 given the fact that ice and snow are everywhere in my area. But you guys answered my question! 💡 Thank you!

I do know a way to use ice water to cool an air-to-air intercooler or a radiator for that matter. My friend uses it on his auto-cross CRX. He usues the system mainly to keep his engine from overheating during the run. But on a hot day the setup did show a 1.5 hp gain on the chassis dyno.

1. Get a 1 or 2 gallon fluid tank
2. Get a 5-7psi low flow electric fuel pump
3. Modify the tank so the pump draws from it
4. Mount the tank and pump under the hood AWAY FROM HEAT
5. Wire the pump to an on/off switch on the dash
6. Plumb the fluid output from the pump so it sprays onto the intercooler
7. Fill the cooler tank with ice water before the run
8. Spray the ice water on the intercooler as desired

attached is my friend's very poorly drawn picture of the system...

Again the day he got to a chassis dyno to test if the setup made power it was a hot day...

Thank you Slim! And thank your friend too for the diagram. I'll see what I can do when the weather gets a bit warmer. 👍

 

[slimer90210]

No problem, and good luck...

P.S. tell me if it works for you...

since when was 3" piping small for anything?
yeah that sprayer dealy was in a sport compact car at one point too. they had more detailed instructions but its a pretty basic idea anyways. lol i would set one up in my 924 but i want to keep it original <8- )

How long ago was it in sport compact car? I wonder if my friends got it from teh mag or if he came up with it on his own.....

And you could put one on your 924 and still have the ability to make it stock again. Just plan it out carfully. Run your wires and plumbing along existing routes. Use existing bolts/studs to mount everthing. Don't cut ot drill anything on the car. That way you can use the system until you want to have a stock 924 again, then you just take the system off. No-one but you need know you had it on there....

 

[blargonator]

lol when i said stock just want to restore it then move onto something smaller and better <8- P i will try and locate the SCC if it was in that magazine at all.....it might have been super street. im not really expecting my 2,9XX pound 95bhp beast to be quick so.....maybe it will handle
