Throtle Body Size

**coralcoupe1993** · 11-25-2006, 06:13 PM

Should I have a 70mm or 75mm on my set up?

Stock Shortblock, Steeda #18 Cam, Trickflow Twisted Wedge heads, Trick Flow track heat intake, 24#injectors, 76mm MAF.

I currenty have a 70mm on there, didnt know if I should go up to a 75mm at this point.

If it was a MAX. effort project I'd say hell yeah. If it's anything other than that, pull a little weight out for free and there is your 75mm T.B. in a sense.

unless you use the N/A power pipe. Most cold air intake's pipe's are the same size as your 70mm.

I went from 326RWHP on my 347 with a 65mm TB to 329RWHP with a 75mm BBK TB. It is unlikely your combo is restricted by your TB.

no need to change it. 70mm is good for well over 500hp i'd say. when i was getting mine tuned i asked the same question...with my combo 70mm was fine.
