Combating the heat

[Justkiz]

everyone seems forgot about AVO kit, is anyone here with AVO kit having much heat issue as front mounted turbo kits?

Fenders are indeed functional, both for getting heat out of the engine bay and oil cooler(via aft front wheel side vent).

A cheap, ZERO Cost alternative is to remove the side fender garnish/vent/scuddle altogether to allow venting, removes additional weight. too.




Also other things you can consider doing, these are pretty much 'free costing' mods, the best mods of all

Drill air ducts into the front bumper to force more air into the engine bay.
You will have to drill a whole bunch more. Pic of my setup, similar idea to the Evasive car but not as nicely finished
Note this is only for my HKS cold air feed..

It is functional. You can see the AVO panel filter in this picture.



Remove drilled plastic shroud behind stock intake snorkel for better airflow to radiator.

Stock shroud in place.

Stock shroud removed. Shroud is on the bottom near the supertones.



Remove rubber seal on top of engine bay for better cooling. Hot air rises, so remove any restriction for hot air to escape which is this rubber lining.



Another mod you could also do is prop up the base of the hood(closest to window side) with 5-7 spacers, a little bit ghetto.. not too sure if the bonnet will be able to be closed though, I've never tried it.

And if you want to spend some money you could probably heat wrap anything close to the turbo(Rad piping) to maybe slightly reduce coolant temp.

This is a good question and I don't think I've heard of any AVO owners complain about heat or unless they're keeping quiet about it. haha

@Stevo_12 was hoping you would jump in and post a few more angles of those vented front fenders just so that others can get a better idea of how they look. Glad you shared your other mods. Thanks!

Turbos are pure heat in the engine bay and placing it right up against the rad just isn't a good idea if you ask me. Our cars just weren't designed to take on that kind of heat. This is why I think Ptuning has the best kit as they mounted their turbo under, behind, and away from the engine.

This is very true. Our cars hold heat very well even without the turbo being in the engine bay. Im currently running the Ptuning kit without any cooling mods and dont seem to have the issues with heat that i hear other FI guys talking about. Given that its the middle of winter here in VA and sadly the most Ive done is take my baby up to the mountains in NC (btw tail of the dragon is alot of fun). Im still very interested in where this thread is going and will probably partake in some of these mods just for the added assurance when i start tracking.

I really would like to see a full test of the kit done. That means 30 minute lapping sessions of brutal hard use. It just seems like nearly every front mounted turbo setup I've seen tends to overheat. This is purely speculation, but the heat of a turbo sitting millimeters from the rad doesn't seem like a good idea. Even the Top Secret/Greddy car had issues with heat when they raced their shop car.

Thanks for all the research.. I've seen some people also cut out the side vent area with a Dremel. What do you think is the most effective mod? I assume hood vents, since like you say, heat rises.

[stevo_12v]

Hmmm I probably wouldn't do hood vents myself due to water ingress when it's rainy unless you like pulley squeal. Oh, just thought of another thing, you could remove the plastic shroud covering the bonnet hinge(to keep out leaves/debris into the engine bay).

Most effective mod, would probably do all those zero-cost mods first and see how you go. Attack the bumper with a dremel for last resort, but definitely remove that shroud covering the front part of the radiator.

I'm not certain removing certain things like the shroud or the windshield wiper cowl are actually helpful and not detrimental to cooling performance. For example, the base of the windshield is a high pressure area, which when removing the weather stripping or the cowl entirely, would cause air to be sucked in to the engine bay and not expelled. Would be curious to see someone test these approaches.

well considering cars having heat issues even on N/A during track days, I don't think it is a problem just in the FI community. The new Griffon TRD car has a wide air duct on the top side of the FR-S "mouth" area which looks pretty good. I think a angled heat exchanger will minimize blocking the radiator.

I think when it comes to track use, you're in for a completely different world compared to street usage with hard pulls here and there.

With air-air IC's, they will never fall below ambient temperatures unless you spray water, so if its 100F out, the IAT is gonna be always 100+. There are pro's and con's with any IC route, but I am going water-air IC and see how that goes during Auto-X.

I think the Seibon hood that has one big square vent in the middle is great for front mount turbo's since the placement seems almost dead on. As for the water intrusion issue with the vented hoods, I'll ask some of the PNW local guys if they have issues in our wet region. Perhaps changing out the hood for winter/summer may be a good idea depending on the wet seasons for different regions.

What about the small plastic piece on the hood on the drivers side?

I'd just like to know what they are designed for before taking stuff off I guess the weather strip is to keep water out? But it's pretty hard to angle water down at that angle.

My suspicion, as seen with other cars, is that your cooling capacity actually will decrease by messing with the windshield wiper shroud. The base of the windscreen is a high pressure area, so air will actually get sucked in rather than expelled. I'd be curious to see it tested, however.

I've read about so many turbo kits installed with the stock radiator and no oil cooler that run fine.

My car's being tuned presently, and with the Robispec radiator/oil cooler installed, my tuner is seeing coolant temps of 220 and has yet to do any full power runs.

I'm worried....a little.

I have the fender garnishes and I'm going to cut those up so they can act as vents, but I'm looking at vented hoods now as mandatory.

The PTUNING kit's turbo location was positioned not in the engine bay primarily for that reason. The whole kit is intended for hard track use. Remember, PTUNING started developing parts for intention of time attack/ track use.
