Time for a C-5

I'm wondering if the stock airbridge is causing any restriction on my car and is worth changing. It has a donaldson filter, 1 3/4 long tubes, CNC'ed 243s and a mild cam (222/226 .600). Right now I have the stock LS6 intake and TB but I have a ported FAST 92 and 90 mm LS2 tb going on. Thought? Thanks.

No I highly doubt it.

I highly doubt it as well but keep in mind that since your going to a fast 92 and 90 mm tb, extra air coming in wouldn't hurt. Take my situation as an example. I have pretty much full bolt on c5, including a ported fast 92 and ported 90mm ls2tb. My intake tract bottle neck at this point is the stock 75 mm maf. Now, I looked at the engine data from the last dyno run and the pressure drop at 6000rpm is only 3kpa or about 0.4 psi. There may be a small 5-10hp gain with the Z06 MAF. I already have the bigger 85mm maf but debating on wether it's worth throwing on at this point or not. Now, you have a cam. You'll probably benefit from more air incoming since you have better flowing heads and a cam, especially if you also have a better flowing exhaust. So, do you NEED a bigger air bridge? Probably not. But I think if you wanna maximize your performance, a larger intake tract with perhaps a 85mm maf would definately net you some hp

Thanks Darkhorse. I already have an 85mm mass air meter (all 01-04 cars). Just reading mixed reviews of the benefit on the bridge...

No problem dude. Well if you already have a bigget maf, maybe looking into a cold air Induction, ram air (vararam, honker, etc) would benefit you. A larger and smoother intake tract would benefit you
