Bradb Posted May 9, 2002 Share Posted May 9, 2002 Ad how much did it cost? Are you getting a loud sound? Any real performance bens? Mi curious/stupid. Quote Link to comment Share on other sites More sharing options...
Adam Kindness Posted May 9, 2002 Author Share Posted May 9, 2002 i bought it at the same time as decat/exhaust/BOV but they havent come yet! so, as i expected the performance hasnt increased (that i notice) cost - about 100 or more... cant rber!! Noise- just that 'ptishh' noise... i have a std exhaust on my car, so its still quiet as till you lift off.. Maye a wee bit more of a throaty noise on acceleration..

Branners Posted May 9, 2002 Share Posted May 9, 2002 Once you get the BOV on there the noise from both together gets much louder. You should be getting an induction 'roar' from the filter, but if you are running at stock boost then it will be much louder once you have modded the car.

Andy Posted May 11, 2002 Share Posted May 11, 2002 I had one of these fitted but took it off, I find my Supra runs better now, than it did with it on! Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 11, 2002 Share Posted May 11, 2002 That is unusual, may be your BOV or surrounding pipework had a leak. Quote Link to comment Share on other sites More sharing options...

I swapped out my HKS induction kit for the stock airbox and noticed the car felt torquier/tighter lower down in the rev range. I have since taken the stock box off and am currently running with a K&N kit. Doesn't feel as torquey/tight in the low range but car builds speed (seemingly) more quickly... Can't explain it really. A dyno day would help though Rgds Quote Link to comment Share on other sites More sharing options...

I really noticed a power lag at low revs and after low speeds or standing still when air temps were high. Taking the OS headlamp out on the track eliminated this problem totally. I guess as you say the only way to tell if there is a signiifcant difference in power or torque would be to do an induction swap while the car is on the rollers.

One other thing I might try is the stock box with a drop-in filter (K&N or other) which should yield the benefit of excellent 'cold-airflow' coupled with the filtration benefits. Filtration aside, the problem is similar to that regarding gas flow through the exhaust, except there is the added 'air temp' variable i.e. Three scenarios: 1) air chamber+smaller diameter pipe+cold air. 2) induction kit+large diameter pipe+ambient air (engine compartment+external air ducted). 3) enclosed induction kit+large diameter pipe+cold air. I've run with scenarios 1&2. Anyone running (3)? Rgds, Quote Link to comment Share on other sites More sharing options...
