Power Gains
 

I was wondering what you guys would think my hp gains would be with a MAC catted Prochamber, Mac Cat back, BBK intake plenum and bbk 75mm tb. I want to change out my magnaflow cat back because it’s always loosening I brought it down to an Acura dealer (keep reading, my cousin is the service manager there) and had one of his guys tighten it up and all that good stuff but it got a little loose again :mad:.

Also what would I need to do as far as my 02 sensors? Do I need any extension or do all four line up on my 03 GT

Maybe 15 hp? I dunno, Id say skip the tb/plenum until you have the gears put in. The tb/plenum combo doesnt do much of anything. You shouldnt need extensions for the prochamber, but you might still need MIL eliminators even with the cats, youll just have to see once its installed.

For your exhaust you have now, get somebody to tack weld it.. it will not move.

forget the BBK crap. get gears

save up for Accufab plenum and 70mm T/B.

70mm not a 75mm???? y or y not

get gears. it will cost just as much as the t/b and plenum. plus that bbk one looks like crap its not smooth on the inside. oh and the throttle body just because its bigger doesnt mean its better.

mine comes loose from time to time just get a allen wrench and tighten it to where you want it then go to a muffler shop and have them tack it in place problem solved. then you have some extra cash to get some pulley's and a prgrammer. :D but thats just me. if i had to do it over again.

only get a 75mm T/B if your going with a Supercharger in the future.

The 70mm is perfect for a N/A car....like mine...
If u get a 75mm and u stay N/A I Highly suggest u also get a tune as you will be leaning out alot...trust me...lol I have a 70mm And i was 20% leaner than normal.. :eek: and your mod engine will crap out sooner....

The 75 mm t/b was dyno proven to make more hp on a fairly stock mustang on modular depot!! :confused:

I gaurantee most people will say go with the 70mm. there is no need for a 75mm T/B on a N/A car..its gonna Lean it out like a leaned out crack fiend.
But hey..if he wants a 75mm ...go for it. ;)

I have a 75mm t/b! ;)

has your car been dynoed with a Air/Fuel readout? lol :eek:
