Mine was $280...high end solargard 32%.

If youre afraid of messing something up with the intake I'd just order this http://www.intense-racing.com/Mercha...tegory_Code=IF and be done with it. It comes with everything you need and instructions. I ordered mine earlier in the week..hoping to get it by next weekend.

Hi. Thanks for your opinions.

1.) Unless AirLift discontinued them, I used AirLift airbags on my dad'* 1996. Order for $60 through Summit. The car was a non computer ride controlled car. Read High Performance Pontiac 10/97 or I can email you a copy of my drag trials with it.

2.) Even though roots-blown setups offer crazy low-end compared to NA counterparts, dyno results show better 2000 rpm torque for the NA vs. the L67. I guess the lower CR hurts output down there or timing is intentionally pulled back at low rpms for the blown non-IC'd L67. Part of what I said doesn't matter since the Bonnes stall higher than 2k rpms and the L67 Bonnes as high as 3200 rpm indicated. Still in the process of achieving the stall rpms, the NA car should do well. I drove an SLE with and without the blower motor and both lit up its tires with ease enough to suggest 2.10 60 foot with good tack and for NA 1.9x sec. 60 foot with a higher stall and traction.

3.) I can't prove you wrong, but the airbox volume and the plumbing on the NA Bonnevilles are identical to the SC'd Bonnies. It seems very generous for a 205hp engine. The same goes for the exhaust. Maybe with higher stall, a muffler swap only would be OK. I know hardcore drag racers who baselined LT1 auto f-bodies to death and added a cat-back vs. a muffler only and got better results with muffler only with pretty much all else being stock. Borla for some years recommended against the 3" cat-back system on auto LT1 f-bodies kept otherwise stock and recommended their rear section system only. Now the Bonne NA has a low stall (as opposed to the high stall blower model). I'm certain the universal rule for decently optimised stock setups will lose low-end with a big exhaust measurable at least by hundredths in 60' and translated to 0.1 second at the quarter.

Typical stock NA Bonnie at sea-level, good air: 15.9s to 16.1s @ 88-89 mph. 2.15s-2.3s 60'
Fearless prediction of a Bonnie with normal radials and intake/exhaust mods: 16.0s to 16.4s @ 88-90 mph (maybe half mph improvement but loss in e.t.). 2.25 to 2.35 * 60'.
Prediction using my proposed setup with drag radials, higher stall, good tune, air bags: 14.9 to 15.1s @ 89 to 91 mph. 1.9xs 60'. Note mph is similar due to no real power increase but slightly higher to do harder launch.

Having experience with both Series 2 airboxes I'd like to add a little here.

The NA stock airbox has baffles in both front and back sections. The front is a long tube that dumps the air into once small section of the air filter. The back is a larger hole into the accordian tube.

The L67 stock airbox has a large diameter opening on the front and nothing in front of the air filter. Then baffling for noise behind the filter. Not identical to it'* NA counterpart..but again, large enough hole going into the accordian tube.

Somewhere I posted a pic of them.

Great post on dissecting the internals.

Sorry to bring back an old thread, but i bought this size at christmas time, just tried to install it today, and it seems to be way to big to fit onto....well whatever it is. My dad says its to big and i need a smaller size. Any suggestions? Or where do i get a clamp to fit this?
