MAF big enough?

[JimmyRGT]

Hey guys Im about to do a head, intake and Tb swap. Going with AFR 165's, Trick Flow Street Heat Intake, and a BBK 70mm TB. Right now on the car I have a C & L 73 mm MAF. I have heard that you need a MAF at least 5mm bigger then the TB. Is this true? Is my 73 big enough to get the TB proper air? Thanks for the help.

It's plenty big.

You can never go too big on a MAF...personally with that set up I would go with at least a Pro-M 75mm or a 77mm and even an 80mm...Yours will work but you will get more power from a bigger MAF...

I believe the 73 won't be a bottleneck to flow with his mods; bigger won't hurt, but I don't think it will help. Correct calibration is more important to focus on than moving up in size in this application - I believe.

Hmmm well when i get all of this installed im going to have it dyno tuned at a good shop and have a custom chip burnt so callibration shouldnt be a problem. Another reason i ask is that i was considering getting the 76mm MAF system from C & L with the inlet pipe and heat shield. I was trying to find another reason to justify the cost of that system to top off the mods i can doing. Thanks for all the advice.

It will work fine. Don't believe everything you hear. I heard that a 150 shot of nitrous will make you slower!!!! Read the post for yourself!!!!

Yeah, the same way the CAI will give you 10 - 14 more HP. My friend's worked fine.
