scott87 Posted November 20, 2012 Share Posted November 20, 2012 Ive been looking at fitting an induction kit or similar to the Supra, ive had an equal amount of people saying its good and vice versa. But i have just a few questions. 1. How many people use the universal filters. I really cant see why a piece of foam or whatever should be hundreds of pounds when im going to have to custom fit it where i want it anyway. If people do have universal jobbies which one. 2. If i were to buy a washable panel filter could i place this in the original airbox and remove the fold down cover? I would obv make a surround out of metal or similar to stop water and would clip the filter in place. But would this not give a huge surface area and be the same material as an induction kit?

Swampy442 Posted November 20, 2012 Share Posted November 20, 2012 Anyone who know anything will tell you the standard, well insulated airbox with its direct cold air feed is the only thing to do, unless you have an FMIC and have no choice. A stock Toyota filter flows more than enough air, but you can pick up KnN panel filters etc. Quote Link to comment Share on other sites More sharing options...

scott87 Posted November 20, 2012 Author Share Posted November 20, 2012 Ok thanks. Well i may get a cheap one and do 2 dyno runs to see if there is a difference. Would a sealed induction kit not be better than the standard panel? Like the bmc. Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 20, 2012 Share Posted November 20, 2012 Stock airbox with both cold air feeds is better than any induction kit even on a TT with FMIC Quote Link to comment Share on other sites More sharing options...
scott87 Posted November 20, 2012 Author Share Posted November 20, 2012 Stock airbox with both cold air feeds is better than any induction kit even on a TT with FMIC Brill thanks. And those feeds are good enough. Not worth increasing the size of the feed pipes? Just asking as after changing a few bits the car feels a little air hungry.

Toyota did a pretty good job in the first place so no need to mod it but the 2 cold air feeds are a must Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted November 20, 2012 Share Posted November 20, 2012 There is so much faith put into the stock airbox and its abilities I even went to the trouble of custom piping my NA airbox (with TRD panel filter) when I did my TT conversion!

Did you keep the stock cold air feeds or beef them up a bit? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted November 20, 2012 Share Posted November 20, 2012 Looks good. Did you keep the stock cold air feeds or beef them up a bit? Kept them as they were/are. I do run with the bonnet raised front and rear though, to aid cooling over the engine. This might allow an extra charge of air to find its way to the air filter housing from that particular feed but nothing has been, or ever will be, measured or proven by me to support or rubbish this theory.

Nic Posted November 20, 2012 Share Posted November 20, 2012 (edited) Ok thanks. Well i may get a cheap one and do 2 dyno runs to see if there is a difference. You may see a slight increase in hp with an induction kit on a dyno, but running a car on a dyno with the bonnet open and huge fan blowing air across the front of the car/engine bay does not replicate actual on road performance.

Dnk Posted November 20, 2012 Share Posted November 20, 2012 Have a whip round and i'll pop my car on the rollers and back to back test the airbox against an Apexi dual cone induction kit Quote Link to comment Share on other sites More sharing options...

Agreed but for the sake of the test i'd do it with the bonnet shut or its simply a pointless test Quote Link to comment Share on other sites More sharing options...
scott87 Posted November 20, 2012 Author Share Posted November 20, 2012 Agreed but for the sake of the test i'd do it with the bonnet shut or its simply a pointless test Yer that would be the plan. Although i wasn't hoping to gain much hp, just increase airflow in. It just feels restricted at the mo.... I just dont want to make things worse, that is my main reason for so so many questions.

Dnk Posted November 20, 2012 Share Posted November 20, 2012 On a TT Blitz, Apexi, K&N and HKS all claim between 13-14 hp if my memory serves me correctly Quote Link to comment Share on other sites More sharing options...

Dnk Posted November 20, 2012 Share Posted November 20, 2012 What do you mean, air-hungry? How do you know it needs more air? I was about to ask the same question, what do you actually have on your car now regards its air intake ? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted November 20, 2012 Share Posted November 20, 2012 Stock all the time for the win. Also as advised its easy enough to modify with a FMIC. Quote Link to comment Share on other sites More sharing options...
scott87 Posted November 20, 2012 Author Share Posted November 20, 2012 (edited) I don't know the car just feels a tad restricted since emproving exhaust flow, maybe it's just me tbh though. I have a new oem filter. Edited November 20, 2012 by scott87 (see edit history) Quote Link to comment Share on other sites More sharing options...
Littler Posted November 20, 2012 Share Posted November 20, 2012 What exhaust have you put on, with it being an NA has it lost back pressure due to a bigger bore exhaust? Quote Link to comment Share on other sites More sharing options...

No it feels much better since the exhaust. And I still have small diameter tubing a second decat and first cat still fitted. Quote Link to comment Share on other sites More sharing options...
