. That will make the most. But yes the 102 owns everything on any setup. 
Comparing air box lids.
Actually if you knew about airflow you would know that a smaller cross section equals faster velocity assuming that the volume flow rate of the incoming air is assumed constant between the two different sized lids...
and I bought my car with under 10k miles on it from an elderly couple who drove it on Sundays and I bought the SLP lid brand new and I have had a scuff in the very center of it where my hood has hit ever since I got it...then again that was back in 2000 so maybe you got a newer redesigned lid from SLP...either way I don't see why you have to take it personally that MY slp lid rubs my hood...that's ur issue not mine bc personally I dont give a damn if my frickin lid has a scuff on it. I'm not that **** about stuff that, i dont worry about anything esdies the mechanical condition my car. Only aesthetic I care about is my paint.

Again anything before the intake runner doesn't do jack **** for velocity. Thats why you can run a 100mm intake tract with no ill effect on stock internals. Intake and head runners and the head ports determine velocity, not the lid and tb.
The velocity isn't quite the same when comparing lids as it is with say a stg 1 PRC head VS an AFR 205 head.
The AFR 205 heads have insane velocity, it is THE reason they are bad *** heads and work on anything from 346 to 408s.
The air BEFORE it gets there, get as much as you can. CHRS1313 ram air/large diameter lid/larger MAF (or speed density)/FAST 102 setup... I don't care if its otherwise a bone stock car or a 427 on the jug, its going to make more power and be faster/quicker.
You can't look at this and look at it the same as comparing a cathedral to a rectangular head, IE. an AFR VS L92 on a 6.0.

Great minds think alike... Something like that.

I totally agree with the fact that intake tract velocity is nowhere near as important when compared to cylinder head air velocity...but you can't discount the theory in my last post bc it's true...instead of condemning my post just state what you think/know and then the guy who posted the original question can take whatever he wants from the conversation...but don't you think that velocity of the air right before tb has anything to do with runner velocity? Not saying anything you said was wrong I'm just trying to look at it from a complete system perspective you know what I mean?

Haha you are 100% right lol! I have no idea how I ended up staying up til 2 am to have a such a heated discussion about lids! To say I think too technical sometimes is an understatement! All this posting and people who do LS swaps don't even run lids lol. You guys get up in arms quick though no matter what the subject! I look forward to doing battle in the future...take it easy guys (even the haters...just kidding I don't think I can take another gang beating

The only issue (Before the whole "doesn't do jack **** for a stock motor" arguement is started) is with the new 100mm MAF. It's takes quite a bit of tuning to compensate for the loss of velocity due to the incoming air now being "slower" so to speak. Tuners that have experience have no issues... I've read about some horror stories however.
Steve, you thought about getting a Saxon MAF screen to straighten out the air flow for yours?

Absolutely not. Hell I didn't even research the purchase (which is unlike me). Pulled a pair of Jordans out of their box in the closet (I wear them about once a year) and money fell out. So I bought mods 
True story.
True story. A larger lid/ram air setup will NEVER hurt performance, too big heads (valves/etc) will hurt performance.
A large TB and a large MAF can be hard to tune.
Keep in mine also, the Ls1 is designed in such a way that you can only get so much going with a larger lid/tb/etc setup. A 92mm TB (even on a Mamo ported 102) is going to make within 1-3HP as a 102, sometimes the same amount because it is a tad more difficult to tune.
With that said.. My new setup is: Chrs1313 ram air/FTP lid/85 MAF/ported FAST 92/92 setup. A stock MAF is not a restriction until 450-500Rwhp FWIW.
