I recently purchased a vortech s-trim, and currently my set up is looking like: cobra intake mani., b303, gt40x heads
Well my question was... would changing my cobra intake to a holley systemax make a huge difference?

I'm not sure ifit will be any better due to it being supercharged. You already have forced Induction with that blower. I may be wrong. What injector size are you running?

the holley systemax intake is a GREAT intake for forced induction

I think it will, the Cobra is best for n/a while the Holley is best for f/i

I'd reccommend swapping.. the cobra has it's limitations

man if u have a chance to pic up a holley for good deal then do it if not the cobra intake will be alright until u can switch

either a holley or a rpm 2 would be good

FredP

money isnt an issue... i know the cobra stops making power after so many rpms what would have the highest rev the holley or rpm2

jtmustang

not sure but both are real good for boosted apps. i have a rpm 2 on my 306 and the ports are huge i had the gaskets that trickflow called for a 1250 i believe and the rpm calls for a 1262 and i shoulda port matched the heads.

so u will have to dig up some flow rates if u want to find out both are good intakes and about the same unless used

I believe the holley is good to 6000 or 6500.. it is comparable to an rpm intake
