Arron Posted August 18, 2013 Share Posted August 18, 2013 Right then, with the high temperatures lately, the supra turbo system is no-where near as great compared to cold temps (dense air). And the great dense air is usually available when the roads are unsafe or it's unsafe to travel at high speeds. That said, we don't get the best pleasure from performance when the car wants to. I had a great idea, some may choose to differ but give me a second guys.. If a custom pipe was made and a feed taken from one of the 2 drivers vents (behind the dash of course) and then channeled through along the inner wing and pointed at the air intake filter, surely that would give a fantastic response even in high temps? yes? Just crank up the air con and pedal to the floor! For those of you critics you could add a shut off valve so hot air is not channeled through during winter when the warm heater is required Crazy but a fantastic idea mi thinks! Any feedback or comments please We all know what the Supra is like when the air is nice and dense! what a cool feature to add some cheap but awesome bhp during summer Link to comment Share on other sites More sharing options...

Lee P Posted August 18, 2013 Share Posted August 18, 2013 You would be better off having an airbox that the filter was mounted in and then use an ac matrix similar to the one inside the car. Air going into the engine gets chilled first as it goes past the matrix Blowing cold air on the filter won't do much as it won't be able to keep up with engine demand.

bignum Posted August 18, 2013 Share Posted August 18, 2013 Pretty sure your aircon shuts down on wot?, also aircon systems do sap engine power and i binned my complete aircon system to save weight. Link to comment Share on other sites More sharing options...

Guigsy Posted August 18, 2013 Share Posted August 18, 2013 the aircon robs hp anyway. it would be much easier to remove it. i think you would see similar results in bhp. Link to comment Share on other sites More sharing options...
kitch79 Posted August 18, 2013 Share Posted August 18, 2013 Haha... Doc Brown off back to the future Im no car wizard so dont know the ins and outs, but with my limited knowledge I think it would work! Not sure if enough air would be blow in fast enough tho. Re. temps, my 2nd week of ownership was that mad 30 degree humid horrible week we had a couple of weeks back, I thought my turbos had broke lol. Its was crazy how different the power was!

Arron Posted August 18, 2013 Author Share Posted August 18, 2013 No much, I was doing 140 today with air con on, kick down at 110 and the car was eating up the road. At low speeds I agree there would be a marginal difference but not at high speeds when the sheer momentum of the car would just take over the aircon robs hp anyway. it would be much easier to remove it. i think you would see similar results in bhp. - - - Updated - - - lol http://2.bp.blogspot.com/-88f10irxW1U/TbGXKaazsJI/AAAAAAAACzw/AXOmx10Lwuw/s1600/Not+Sure+if+serious.jpg - - - Updated - - - Obama said Guantanamo would close down, but has it?

David P Posted August 18, 2013 Share Posted August 18, 2013 (edited) It does actually give more than it takes and was a naughty trick used by one of the Rally Teams before they were found out. However, air con systems are nowhere near as efficient with the post 95? safe gas. Edited August 18, 2013 by David P (see edit history) Link to comment Share on other sites More sharing options...
Arron Posted August 18, 2013 Author Share Posted August 18, 2013 Trust me with a few minor tweaks it's an awesome idea. Obviously the ac on it's own wont be sufficient!! No way. However it will make driving in summer so much more fun that's a 100% surety Haha...

Arron Posted August 18, 2013 Author Share Posted August 18, 2013 No way! My air con throws out really, really cold air (topped every year), ditching 15-20 kg of an aircon system which would make driving a supra a pleasure in summer is no comparison. It's a myth, only at low mph's it would affect bhp, but we're talking pedal to the metal baby lol the aircon robs hp anyway. it would be much easier to remove it. i think you would see similar results in bhp.

Noz Posted August 18, 2013 Share Posted August 18, 2013 Cooling intake charge is one of the best ways to increase performance, as your improving the system and components you already have. The only thing is, by cooling with co2 or aircon systems really you want to make sure your optimising heat surrounds and fuel temps, and ducting (ask duct-king slutters for more info ) Though. If this hasn't been done before, and you fancied a challenge. Providing data with and without system activation could be a great comparison? As without it's merely guess work again if it would work or not. Data is power. Link to comment Share on other sites More sharing options...
Arron Posted August 18, 2013 Author Share Posted August 18, 2013 My car is up for sale so cannot try it on her I think apart from the tricky pipework to the engine bay it's a breeze. After taking into account the comments I would definitely attach the pipe to the standard airbox system but have the pipe coming into the airbox at a 45 degree angle (from back of car) so as to avoid "over-sucking" (just this once lol) from the air con system. Agree, without data it's pointless, but i would put my last dollar on it that it will make a HUGE DIFFERENCE.

Guest Roger NE Posted August 18, 2013 Share Posted August 18, 2013 Interesting idea . . . as some have said, you'd really have to put it on a Dyno to really see what the difference was. I would have also thought you'd get more power gain on an N/A than a Turbo engine. But the basic concept is why I've always thought it stupid that some people put aftermarket air filters inside the engine bay, sucking all that hot air into the intake . . . rather than the stock filter system sucking (and ramming) nice cold air from the front of the car !

Arron Posted August 18, 2013 Author Share Posted August 18, 2013 Couldn't agree with you more. However, I don't think dyno would be necessary as you would definitely "Feel" the difference when it wakes up. But yes dyno would be beneficial for the "data" back up Interesting idea . . . as some have said, you'd really have to put it on a Dyno to really see what the difference was.

Thomas_germany Posted August 19, 2013 Share Posted August 19, 2013 AC takes hp - that's clear. But if you don't want to get rid of the AC system and you're using the AC anyways, I think it's worth a try, to use the cold air. Link to comment Share on other sites More sharing options...
np89 Posted August 19, 2013 Share Posted August 19, 2013 I would actually love to see the air con system you're going to plan to run to supply say for instance the 15,000 litres of air at 5,000rpm that your engine requires........... Link to comment Share on other sites More sharing options...
Guest Roger NE Posted August 19, 2013 Share Posted August 19, 2013 Surely it's only 3,750 litres (per minute) at 5,000 RPM? But even so, that's one of the things I was thinking earlier too. You don't get something for nothing . . . so the power (from the engine) required to cool that much air would surely outweigh any power gains. It's a bit like these Electric Superchargers . . . the only way they MAY work is powering them off a battery which is only used during boost/acceleration and then only connected to the Alternator and re-charged during cruising.

I could well be wrong (and probably am), but I was basing on 3litres x 1 revolution per min = 3 litres and therefor 5,000 revolutions would be 15,000 litres given that the volume of fuel injected is negligable and a little bit if the air is pressurised on boost?
