85 mm MAF sensor sorry, I know this question has been asked many times with differing answers. I would not even bother with a bigger maf except I'm getting to near 600rwhp soon. here's what I have:
92 fast intake and 92 mmm throttle body
ported heads
very mild cam (221/229, 116lsa, .6 lift)
1-7/8 headers
procharged
looking for 600rwhp depending on sc pulley
is an 85mm maf worth it? I will obviously be tuning my car in April.

I'll ask my tuner if he's going to do a speed density tune. At 600rwhp do you think it's worth going to the 85 vs the stock maf?

A "stick" style MAF is might be an option, then it can just go in the intake tube somewhere in front of the throttle body. So there is no MAF restriction involved.
Not sure if the late style one is compatible with the early computers, but Porsche uses one as well Fomr the early 2000's.

In my experience the less restriction to air the better you're off. My last build I was pushing 540 rwhp and I had an 85 maf at the time with a ported LS2 intake/90mm throtle body. Now can you got too big of course. I wouldn't do a 100mm with 600 rwhp but you should be fine with an 85mm.

I definitely think you'll be fine even with a 92MM tb and manifold. Let us know what he says and how it all turns out.

He didn't elaborate in his very brief email, but I'm guessing my suspicions are correct. It didn't sound like he thought it was a must.. It isn’t a massive restriction, but it still is a bottleneck.
I forgot to ask him if he's planning on doing a speed density tune. I've heard of some people doing a speed density tune and keeping the maf for data logging. Then again, tuning is like a foreign language to me.
He said he would personally go with the 85mm maf because the stock ls1 maf is pretty small.
