BAC5.2 Posted November 19, 2011 Share Posted November 19, 2011 if i put a leaf blower directly on my turbo inlet would it spool faster? Yes.

grizzlyfarmer2 Posted November 19, 2011 Author Share Posted November 19, 2011 Lag is actually the time it takes to get the turbo rotor spinning at full speed. The larger the turbo, the larger the lag, but everyone knows that already The length of the tubing or the size of the intercooler have very little effect. So say my 10 ft of tubing was as efficient at transferring heat as an intercooler would I see less lag or would you still say it is the turbo?

If you can fit 10' of tubing into the opening below the radiator, have the tubing finned to help with the heat transfer, then yes it would be as efficient. Might be easier to fit a FMIC though.

itsme Posted November 20, 2011 Share Posted November 20, 2011 But if you ever put the intercooler back in, make sure you wash it with lots of soap. I thought soap was bad for the intercooler?:lol: Racer X FMIC for '05-'09 LGTs, '08+ WRX and '10+ LGT,'14+ FXT, and '15+ WRX TMIC Racerxengineering.com Link to comment Share on other sites More sharing options...

Well no. I have not seen any new way to bring the temps down besides air to air or air to water intercoolers. They work well and don't cost much.

underground000 Posted November 22, 2011 Share Posted November 22, 2011 yes that has crossed my mind Cooling of the air out ways the restriction (if any) also the intercooler is much bigger then the pipe's diameter. So the the added number and volume/diameter?? of tubes in the intercooler should be close to the pipe Hope I'm right...

NSFW Posted November 26, 2011 Share Posted November 26, 2011 Correct. People generally go with a larger turbo at the same time they fit a FMIC though, and then blame the lag on the intercooler when it's 75% turbo and 25% IC. I agree with this. I ran a FMIC with the stock turbo for a while, and it wasn't nearly as big of a deal as the internets predicted. Grizzlyfarmer, the turbo heats the incoming air a lot more than you seem to think. If you get a chance to put your hand on the IC of a car that's just finished a dyno pull, try it. You're not likely to burn yourself but it does get toasty. If car manufacturers could get away without putting them on their cars, they would. They've tried it in the past, like BAC said, but I can't think of any turbo cars from the last 15 years or so that don't use intercoolers. (Anyone know of any?) I've seen pictures of intercooler-less setups that used water or water-meth injection for cooling, but I don't know if it's been done on a Subaru yet. I vaguely remember someone talking about it on one of the Impreza forums, but I don't know if they followed through. If your 10 feet of plumbing could cool the intake charge as well as an intercooler, that tubing would be an intercooler, in every sense of the word.

fahr_side Posted November 27, 2011 Share Posted November 27, 2011 If you run pure alcohol for fuel, you can use it's latent heat capacity to cool the charge enough to get away with using no intercooler, as below.

ChefRacer Posted November 27, 2011 Share Posted November 27, 2011 hmm, well has anybody tried to make a turbo where the hot side and the cold side were on opposite sides of the engine bay, so the exhaust gas isn't heating up the intake side? I'm pretty sure I've seen superchargers built like this, where the belt driven side was on the opposite side from the intake side. Wouldn't it make sense to keep the two sides apart, even if you are losing a percentage of the power to the distance between the two sides, wouldn't the lack of heat make up for that loss and then some?

underground000 Posted November 27, 2011 Share Posted November 27, 2011 too much money and room, your reading too much into it. if people can make 500+ hp STI with a turbo and 4 cylinder, then the heat is not that bad thats why they have heat shields and thick pipes (oem) or wraps and coating (aftermarket) to keep heat down stock car the car is getting cold air from out side, turbo heats it, intercooler cools it. would be different if you have an intake in the engine bay with no way for it to get air from the outside. and more prone to failure of the turbine shaft when it has to reach 4 feet across the engine bay also means dual cooling for both bearings on each side of the turbo...too much money when the current config works 5eat downshift rev match:) Powder coated wheels: completed:) Link to comment Share on other sites More sharing options...

It isn't the exhaust gases that heat up the air, it's compressing it that does. You can put the "cold" side on a trailer behind and the air will still be hot Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
Rancid Posted November 29, 2011 Share Posted November 29, 2011 With the volume of air moving through the turbo I couldnt imagine the cold side being that much warmer than ambient. PV = nRT Link to comment Share on other sites More sharing options...
