Stock air box tricks?

[DKREDT]

Are there any "known mods" that you can do to extend the performance if you use the stock air box system?

I am working on ways to make my car look original as possible while balancing the best performance enhancements that I can with the stock or stock appearing components.

Thanks,

Joel

Along with a K&N filter for the stock box, Kirban markets an aluminum lid to increase air flow. Looks stock from above.

I think you can remove the lower section to get more air flow.

I've cut the bottom out of the stock box and cut the mounting bracket in 1/2 and rotated it around to support the fwd and back lips of the lower box and provide clearance for a 6.5" cone filter.

On the top box I removed the inlet restrictions and modified it so that a slightly modified (inlet shortened, smoothed) LT1 MAF sensor would fit inside.

Barb and roller cabinet door fastners snap the top lid to the base.

Here is a picture of the set up out of the car

And a picture of it mounted in the car

My white T-type when 11.53@118 with drag radials, bluetops, a TA 49 and a stock intercooler with a big neck using this aircleaner set up so it shouldn't be a restriction for most street driven TR's.

Cool. Thanks for the replies guys. I had a spare air box laying around. Tonight I started playing with it and opened up areas on three of the four sides of the bottom with my dremel and a cutting wheel. That should let some good air in under wot. It does not look like the openings will be very visable either when the maf duct is installed etc...

I will try this first and see how it goes!


Thanks again!

The box is a restriction, but once you open the bottom, the throat/shaft mount were the elbow attachs becomes the next largest restriction.

That's why I went to alternative method to attach the top of the lid to the bottom rather than use the factory shaft/nut.
