hi im trying to get more power out of my 87 non turbo with no cats,removed air pump and bac and now i got to buy plock off plates, what else should i remove and do to increace acceleration, my car will top out at 125mph how do i increase that? anyone please help me!!!!!!

 

lol... is this a racecar? cause 125 is plenty fast! and the only thing that will actually provide any noticable hp gain that you removed would be the cats! your pretty much maxed out on removing stuff... you might want to think about actually investing into performance parts! not just tearing apart your car... a nice streetported motor would be a very rewarding upgrade... or a full header back exhaust... cold-air intake...

 

As far as bolt-ons, consider the S5 UIM swap for an extra 10 to 15 dyno-proven HP. The write-up is here:

Also, check out the Community Modification Manual, it has an N/A performance guide:

And did you mean ACV when you said BAC? I'd keep the BAC so your car idles well!

 

off the subject, but does removing the air pump have any negative effects on for the engine

 

The S5 aux ports use the air pump for pressure. S4s don't really use the air pump for anything but emissions.

 

Its pulley is also used as part of the system to turn the water pump.
