treadstone sells maf honeycombs, or there is a company on ebay called mrpmachineshop http://www.ebay.com/itm/251903562952?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
I've contacted them through ebay and they said they can make custom sizes as needed. Saxonpc was what I originally had posted, but after more then 2 weeks of run around with him saying he missed my order and then told me it was shipped and then forgot to ship it, i wound up getting it elsewhere.

Koren

Thanks man I wanna build a air intake cause my stock box has a hole in it, no honey comb anymore and my tubing is ugly lol, but I also don't wanna put out 200 for a Cai box from cold inductions.

Wondering what your MAP is reading when the engine isn't running. I was looking at mine and it was at 96kPA at WOT as well and the atmospheric pressure was at 102kPa. Then I looked at my MAP readings with the car off and it read 97kPa. So my deduction is the MAP isn't the most accurate in the world, at least mine isn't. I was worried I was pulling a lot of vacuum too, but 1kPa is about perfect considering MAP location and everything.

Depends on the atmospheric pressure outside but I measure it two ways, KOEO is usually about 100-101, and then i verify it by the barometer on my phone. My elevation plays a factor as well though, I believe im only like 10 feet above sea level here in jersey.

You seem to be pulling a ton of vacuum then, like 4kPa. Also another thing that struck me is your Hz read a lot higher than mine at WOT. Granted the 20 different companies making LS7 MAFs will very but I'm only reading like 8700? I believe at 6.8k RPM and my cam is decently bigger than yours.

Well, the hz range directly relates to the air velocity passing over the MAF, not nessecarily the overall volume of air the engine is taking in, while you could probably compare it against each other, another thing that will make a large different is which maf tube we are both using. One of the things that threw me through a major loop was the spectre maf tube wanted roughly 20-30% more fueling across the MAF scale, where as the airraid did not. Even though they are both considered 4" MAF tubes, the airraid is probably about a 1/16th to an 1/8th of an inch smaller ID, another major factor is that the airraid also sits the maf wire directly in the center of the tube, where as the spectre has it sitting much higher up in the air stream. So realistically the only way to directly compare is if we are using the same maf tube.

4kpa is high, yes, however significantly better then before lol I was almost 8kpa off from atmospheric at WOT starting around 5k with the LS4 intake setup, now im only seeing that 4kpa difference right at the peak RPM. Regardless of the cam specs, our cars are only going to be able to pull so much air through at any given time depending on our intakes. I see your one of the guys running the FAST 92 swaps, you ever get a dyno done or have some track times that I could compare to?

Yes it was with my old cam however (216/220 .56"/.56" 114+4), otherwise the rest of the mods were the same.

This is with a LS6 IM, CAI box, and the rest stock LS4 plumbing:



And this is with the ported FAST 92, ported LS2 TB, LS7 MAF, and 4" plumbing and cone:



I'm sure with the new cam I'm running I'll really start to benefit from the FAST and the heads. I haven't had time or money to take it back to the tuner so I've just tuned it myself for now.

You didnt see any increase in power from the LS6 to the fast and bigger intake? Kinda disproves the concept of the intake pipe and LS4 maf being the restriction in the system. lol Which one of those dynos had the heads on and whats the spec of the new cam. 216/220 is very close to what im running now. 214/220 .540/.535 115+2

lVloses

Both of them had the heads. Only thing I've changed since the last dyno graph was the cam and went with stock head gaskets (was running some cometic .040" gaskets before but it limited my timing). New cam is in the mid 220s with a tad over .6" of lift with a 114 LSA +2 and still running 11:1 SCR and 8.5:1 DCR.

And I agree especially on a stock car it won't gain you any ponies lol. But other people disagree with me so I'll let them choose.

Ah i woulda been curious to know how much you gained from the TFS 205's, i know there was a MASSIVE increase in power going from the LS4 intake to the ported LS2 from CSP with the 90mm LS3 tb. At least 30whp if not slightly more, makes me very anxious to get back to the track once I get this steering stuff sorted out and see how the times have changed.

well its to bad this is the only ls6 to fast intake to date with a follow up dyno. The only other fast 102 swap never had dyno numbers back to back. Also there are people Maki get more than 350 wheel with the same mods. So my theory on his build is just that that something good was not properly setup.during the build. For a h/c/I 5.3 these numbers are very low.

Look at DavidGXP's old setup. He had LS6 IM, same heads as me, slightly larger cam (218/222 I believe) and he still put down 350whp. My pulls were also done in 2nd, it was making more power than 3rd and 3rd was spinning my tires over their rated speed so we stuck to 2nd.

iTrader: (2)

Well its not accurate in 2nd, thats the problem, 3rd gear is your 1:1 ratio. lol You also have unlocked and locked converter dynos i noticed.

lVloses

iTrader: (1)

2nd was consistently ~5whp more than 3rd was, don't know why, I even questioned him about it and he wasn't sure either. And I assumed he was using 3rd and locking my converter on the first graph however when I went back for some fine tuning I asked him and he told me they were both done in 2nd. Sorry I never got back to that post and edited it lol. I did get my TEP transmission installed between these two dyno graphs though. Besides that it's virtually the same mods.

you should throw this up in the sticky thread parkave, im sure ill be adding to it in time.

How much bigger is it? You must have a garage full of TB's now lol.

the plate size is still 90mm, i havent measured the different between the two on how much wider the mouth is though, the concept is it supposedly improves the venturi effect between the throttle body.

Still waiting on that clip ! =P
