![]() Stock 86GT w/hypertech chip, 5spd, 2.73s
Which is a better choice, K&N filter in the stock airbox, or a complete CAI such as MAC, BBK, etc.? Anyone have any mounting problems with their CAI, or any other relevant information that might prove useful in my purchase. Thanks. How are the BBK aluminum underdrives? Thanks for you help, Jeremiah Alexander BTW--I'm hoping for an increase of 20h.p. between the two.

![]() Im guessing your not going to get 20hp from CAI and underdrives, maybe 10 if your lucky. The CAI look way better but im not sure if they are worth the extra money. Underdrives will riddle you with battery and alternator problems from what i have heard on this site so i decided to avoid them personally.

![]() I would get the C.A.I and if you dont care about looks just the added power get some header wrap and wrap the cai cause they seem to soak up to much heat and they get HOT by wrapping the cai you will keep the air coming in a lot cooler and that will help in the power gain.
as for pullies I have the ASP and I love them and they were a little cheaper then the bbk ones and there black so they dont stand out as much but if you want the look get the bbk or march pullies but for the look they cost more

![]() Pulleys are worth up to 10 HP, maximum. Aluminum is good, brands vary in quality. No suggestions.
The K&N in the stock airbox works fine and it's cost effective. The full fenderwell cold air intake kits are over $100. and have some fitment issues. HP gain is about 3, tops. Not a big HP boost but they sound great at WOT, clean up the engine compartment and 3 HP is still 3 HP. Only trouble is, you won't really notice it. I use the Moroso kit which has a plastic intake tube but fits perfectly and never a problem in 3 years. With a CAI kit and underdrive pulleys, you're looking at about a 10 HP gain, maybe 12, maximum. Your money might be better spent on replacing the rear gears for 3.73's. No HP gain but big acceleration gain. |

![]() With the power increase from the pullies and the cai if wrapped you might hit close to the 20 that you want but I am not sure of that
because I did the cai tb and spacer on the same day and I wrapped 2 years later and I seen a little more with it wrapped not to say no more burning my arm on the darn thing when under the hood after driving for 5 mins.

![]() Anyone use the march ram air/pulley setup? They claim 30HP with the package. Im wondering if a person can even beleive anything they see. ANyone watch HPTV? 94 GT. Baseline 165 with a 5 spd. After BBK CAI, Mallory AFPR, Mallory igntion (complete including wires cap rotor coil and ignition box) Flowmaster american thunder exhaust, and all the hit was 185 or 195? The exhaust claims 15hp increase buy itself and the CAI 10-15hp. I guess its all about the money and nothing about the truth huh?

![]() a lot of these companys are talking increases over the whole rpm band not just peak there might be places in the range that got a 10-15 hp increase but the peak only went up 5-7 you have to look at the whole dyno sheet and compare rpm to rpm not just peak to peak
