ported 92mm results
2001 TA M6 completely stock 288hp and 319tq at 98deg
Next 12 bolt with 4:11's ud pulley,lid,xs 1 3/4 headers,ory pipe, hooker catback,spec stage 3 clutch,same LS6 intake and throttle body,17x11 ZR1's with 315 BF drags,comp cams 238/242-601/610@113.5+0 and patriot golds.with a tune it made:395hp and 356tq at 93deg
Yesterday with the 92/92 (ported by Vengence) setup as the only change it made 428hp and 379tq at 88deg all #'s sae.I have a set of there TFK LS6 heads going on in the very near future,so I'll keep everybody up to speed!These results are with no additional tuning.
I would like to thank Tracy at Revxtreme as he was very polite and very helpful! I will be back!
very nice numbers
congrats You go SD and ditch the maf all together, and the entire airlid for that matter yes there's that' kind of power there in SOME cases, but that's not even a guarintee.
FWIW, I've been 9.55 @ 142 mph with a stock, untouched maf, screen still in it an all, with just a 90mm NW tb and a 90mm fast intake, with zero porting done to it.

maybe the poeple you talked about them didn't tune the PCM for the 85mm MAF and 85mm lid. what i know that SLP 85mm MAF doesn't need a new MAF table just a retune where the GM 85mm MAF needs a corresponding MAF table and a retune of course.
If you see 5 hp, it's a miracle, or the weather that day is a good bit better.
Trust me when I say, that it's less then 1/2 the gain people claim, making the cost per HP really out of whack in the worth while department.

If someone actually thinks that a ported fast 92 mm with the bigger maf and lid would help, man up and send me one and we'll do a dyno comparison, I'll make a pull with the car log the timing and a/f and all that, then do the same (adjust a/f to the same) and see what it does...
Every time I offer this, I hear nothing but crickets, because noone wants it to get out that it really doesn't make 1/2 the difference that they want you to believe.
Hell I'll track test it too to prove the point, that I bet the DA will have a larger impact then the intake tract will

i gained 2 hp with the 85 mm maf

tuned with both and tested back to back on the same day while strapped on Futrals dyno.
My stock maf was bad and the 85 was cheaper then a stock replacement so it was not a bad deal.
I can tell ya this, 9.5 @ 142 and it's still not a restriction, so how guys that are making 420 ish rwhp are worried about the maf I'll never understand.
I plan on running sd on my Nova with a built high compression 347
I personally would love to see you throw an 85mm MAF on the car just to see if it picks up anything significant. Like Ron said, it's just one of those parts where some people claim big gains with the swap and others claim little to no gains with the swap. You can always swap back to the stocker if you're not happy with it and sell it pretty much new for just about what you paid for it. But I wouldn't just dismiss an opportunity for possible horsepower just based on what other people are telling you when the general consensus is mixed, and especially when it's less than a $200 part.
I guess it just shocks me that you won't give a $195 part a shot when you'll tear every other little thing out of your car to save 5 pounds here and 6 pounds there. Even if you picked up just 5rwhp, that's like another 50 pound weight reduction! I would have thought you'd be ALL OVER that!
I'll take the maf out before I ever try another one.
You think that if there was another 20 rwhp to get from swapping that stuff that was a 100% guarinteed gain that I wouldn't have don eit with all the $ that I have spent Joe? Come on man, get with the program LOL, I drop 10 grand a year in this car, if there was any bolton stuff left that was gonna give me another 20 rwhp I'd have done it a long time ago.

But again, I understand the going bad and hurting the car bit. If that's your reasoning, I guess I can't argue that one.
I just think that if your only reason is "It most likely won't pick anything up", that's a bad reason to not give it a shot.Read this post, especially the first response which is from Patrick G, who I think we can agree knows a thing or two about these engines and states are typical results from what he's seen: https://ls1tech.com/forums/showthrea...ghlight=85+maf
