I've already reviewed some posts on throttle bodies and MAF's. But none of them really answer the right questions.

When should you go to a bigger Throttle Body?? And what size of throttle body requires you to upgrade the MAF. In other words when does the Stock MAF become the intake restrictor??

I'm going to be running a hotcam with 1.6 RR's and ported and polished heads. Do I need a bigger TB or MAF???

 

Anybody????

 

I'd be interested in knowing this also. My motor...specs below....is almost finished and I want to know if I should get a new MAF and TB right away, they are kind expensive and I just put 6k into my motor so it may be a few weeks before I can get those items.

I would say you could benifit from a larger TB. The stock MAF should be fine though. As a general rule I would say 375 RWHP, needs a bigger TB. Though you won't be making quite that, I still think you would see a benifit though.
