Mine ran 403/38-something and needs a retune for sea level.

I've been wanting a retune, but I want to do the intake first. I'd like to see 440/390 out of this cam. It's a low end Tq cam, so I don't want anything that will kill the low end. It's got a 110* LSA, but only 5* of overlap.

I was just wondering about the MAF too because I was reading that you can go too big and that will throw the MAF off because it won't be getting a "bottle neck" (in a way) in order for it to get an accurate reading of what is really passing by its sensors. Too big is too slow, IIRC. I wonder if it'd be worth it to go SD tune.. I've asked around and the replies are mixed, but this isn't a DD car. It's just a street car.

I've been saying since day 1 that the 102 was too big for an LS1 and everyone was saying "Noez itss not!!! It's amazing!" but I never saw any numbers showing it was any better over a good 92 setup.

And Don, if you find a FAST 92, could you PLEASE hold onto it for me!?!? For a decent price that is. Once tax season comes around I'll pick one up, IF I can find one that is. I found a damaged one on eBay last week, but I couldn't find the outer shell anywhere.

why would sea level tune vs. 4000 feet tune make a difference on a MAF tuned car? maf should correct it self on a few street runs around here. and judging by your numbers your about right on for numbers based on the TSP bloated DynoJet numbers.

Fast sells the pieces to repair there intakes from individual runner to top and bottom "cases" if it was cheap enough id have bought it.

^ I would have gotten that damaged FAST 92 if I could have found the shell easily enough.

If I could find all the pieces, I'd piece together an intake.

Wat Pizza is saying is FAST sells the shell pieces, you just have to call them

[Bayer-Z28]

I was wondering... I'll have to wait till I get my taxes done and give em a call. Doesn't make sense that they wouldn't sell the intakes anymore, but the pieces.

85mm Delphi MAF on the way.. $75 shipped.

Found an ASP UDP with ARP Bolt AND both belts for $170 NIB.. But the fuker hasn't gotten back to me about it yet.

Found flow #'s for the 92 and 102 non-ported. I've been looking for these for YEARS! 4" bore, but nearly same heads as mine. Worked over 243's. I'm running a .639" cam. I don't see the minimal gain being worth it for a 102 over a 92. Shown as head flow with the intake.

Would it still be ok to stick a 92mm TB on a 102 IM?

On the contrary. Check out Mamo's post on here:

Flowed our LS2, 243 CNC'd head on a 4.00" bore. Runner volume is ~225 cc and these are with 2.00" intake valves. These are going on a project here and since we have a few of the new 102's, I figured it was appropriate to update the flow numbers.

Ok,so how does flow translate to hp/tq?
