View Full Version : drilling holes in the corner of the airbox?
good idea or bad idea... just near the headlight so it pulls in cold air
could this possibly increase performance?
:tomato:

No point, it provides adequate air for what you need and little performance gain would occur if any.

yeah, that.

It pulls in cold air from near the headlight anyway.
not such a maxpower idea... it worked on my celica and with a number of other celica owners
Just wanted to know if it was worth it thats all
How big a hole are you talking about?
dunno maybe removing the entire side of the front of the airbox near the drivers side wing
That's not really drilling a hole, is it? :D
A hole that size would tend to suck in warm air from the engine bay, or so I whould have thought.
FYI, general concensus on here is that for anything other than a big single the stock airbox is perfectly good for the job.

The airbox is fine as is, there is NO point in removing it, drilling holes in it, modifying it, fitting a different filter to stock, blah blah. I have measured vac drop on them and it's a superb set up, quite able to feed 500 BHP engines with no real restriction.
ok ok lol
so lightening the car or nitrous it is then
p.s. does the supra have a throttle heater?

It has a throttle body warmed by the engine coolant, yes.
Worth bypassing by any chance?
thanks
Why would you want to do that?

Aiding in decreasing charge temps by any chance?
I've done it on my car and it has no detrimental effect on cold running. I'm guessing it's there for the really cold countries.

I gathered that, but isnt it valve controled?

Not that I remember. Just in and out from the main waterways.

its fed from the front of the head to the TB out of the TB to the iscv so you can by pass no probs. head to ISCV.

I never knew that, always thought for performance sake it would have had a temp controlled valve in line. Must have a good look next time.
No valve.. all part of knowing your way round the 2jz...all learning;)

Well Mig you are the UK god of the 2JZ after all!
Am i ...well if you say so :innocent:
How jolly Max Power
I remember reading Max Power (years ago I might add) and doing that with my Calibra airbox! How much difference did it make... Mmmmm, about 100bhp I reckon! Honest... :rolleyes:
The way the Supra is designed it would just suck in warm air from teh Main fan anyway.
how about make some holes in the airbox and redirect your aircon fan so you get Airconditioned induction!
Now thats what you call INOVATION!

Retro fit some of that plumbers pipe freezer spray to spray onto your intercooler. Be a simple job. All you need is a plunger to push the aerosol down and spray away. 1/4 mile heaven. I can't beleive that no-one does this you know. Its what £4-5 a can. You want stupid cooling then 4 cans a run. I've seen people pay more than that for racing fuel :)

well people could do an awful lot worse than listen to him!

Have a 7pound CO2 bottle fitted in the boot, plumbed to spray bars ahead of the fmic. 10 sec blast of that completely ices the intercooler.
Might bypass the throttle heater then cheers matt.
should be good for a very minor torque increase... best of all its free though :)
Very true (for an already warmed up engine in the summer)
I'm sure you'll find an alternative way to compensate for the loss of fuel atomisation in most other circumstances.:thumbs:
