70mm or 75mm TOB for my setup?

[Blackie Lawless]

Alright so I need some help in deciding which setup my car would most benefit from, a 70mm or 75mm Accufab TOB & Plenum combo.

Here is what I currently have:
Steeda U/D Pullies
Bassani Catted X
Steeda Tri-Ax

Being installed this Sat:
Centerforce Dual Friction Clutch
Fidanza Billet Alluminum Flywheel
Ford Racing Alluminum Drive Shaft
Steeda Clutch Adjustor (Cause you know that improves over all air flow)

For Sure Future Performance Mods:
Bassani Off Road X pipe and Bassani Catback
L/T Headers
Some sort of a CAI like K&N or Demolet
Gears
Performance Heads / Springs
NOS
and a Dyno Tune or programmer like Xcal2

I am riding on 18" Y2K Cobra R's

I don't want the 75mm combo if my setup will not benefit from it. I would rather have the 70mm and keep good air flow/pressure going through my car, but at the same time, if the 75mm WILL benefit my setup, i'd like to know.

What do you all think? (I am looking to make my purchase within the next 3 weeks or so)

i got the accufab 75tb and plenum didnt notice much pull. and i have basically the same stuff as you

i guess with 5mm less you would get less pull.

the 70 mm will be good with your mods. if you ever plan on any forced induction get a 75mm

+1
Or if you are for sure on getting heads, cam, intake manifold, headers...get the 75mm.

No forced induction plans, just a Nitrous kit down the line.

Thanks 4 the replys. I am thinking the 70mm will fit my setup best.

I do not know about size but the Accufab TB is a really nice looking piece.

EDIT:

I like my 70mm. I got it for $52 off ebay, im sure up top a 75 would make a few more with my cams and lt's, but oh well.. it would still be slow anyways

70mm for the mods even if you spray
