2000SS

Inital Results: 7.4 HP gain over an LS6 Intake on a 427 CID F-Body.

This was the 78MM version with ported stock TB, bolted on with no changes to tuning or anything else on the vehicle.

We'll continue the fine tuning this afternoon and post more results as we generate then.

Thanksf or the info but does that mean less of a gain would be seen on the smaller motors?

What was the A/F on the two comparo pulls...

Well, thats not very promising. A 427 should be closer to maxing out an LS6 intake than ANY 346 should. Looking forward to seeing some more results, but its looking like its not gonna be worth the ~$800.

It could be the MAF size, or airbox lid size, or t-body size that is maxing out first, which would not allow the intake to do its job. We'll have to see how the big t-body versions work on these big engines.

Lets see it with a 90mm TB

If that is the case then couldn't you just pull the MAF off the lid and just run it open with no filter just for the dyno? That might be interesting. If the TB is too small to make any gains then I guess the 78mm ones are pretty much worthless at that point.

Personally, I think the only gains this intake will see are mostly from just having a larger TB/intake opening and they will be similar to the TPIS modded LS6 intake with the bigger TB that has already been tested.

MTI put the LSX intake on the flowbench already and the numbers were nicer than the LS6 intake. I'll let them post results, and maybe a comparison graph.

I could fart in the gas tank and get 7hp for free. Better yet I will bottle a fart and sell it to you guys for 99 cents

JF WS6

Hmmm...... Well after reading the results Thunder got I'm not sure now. It's strange the big cubes got less power from a better flowing intake than a nearly stock motor. I'm sure the TB has something to do with it, but you'd figure the extra cfm would benefit the big cubes more.... In any case 13-15 HP (so far) for nearly a grand seems pretty steep to me.

I'm not going to make any conclusions until I see what the numbers look over the next week or so, today everyone was in a rush to post the first dyno numbers.

Any gain is cool just for putting it on, I look forward to seeing what some tuned optimized combos look like.

thunder swapped theres with no tuning and said the A/F was the same? Cant see much to tune?

i know there is at least one tuner here on this board that has seen only a 10 rwhp difference on a 427 motor built for a customer given the same a/f ratio. they didnt post because it seemed low imo. i guess not. i will agree that there are many factors including MAF size, TB size, air box restriction, etc with more free flowing systems, the intake will shine.

Guys come on...the intake has been out for what...24hrs..if that...noone has everthing figured out...I mean going from an LS1 to LS6 intake on a H/C car was a HUGE difference...but that was with porting the TB, and Z06 Maf included...doubt I'd have gotten 20+hp w/out that...most of these tuners are just unbolting one intake and strapping the other on...let them get the bigger TB versions and let them test several different combo's...

I mean 13rwhp on a 346 over an LS6 intake w/a TB that ISN'T the restriction is believable.....then 7hp over a 427 when the TB is already being maxed out.....it's totally believable...

Come on MTI, Come on AS, Ligenfelter...they'll all get their chance and hell they've already shown that no matter the engine you're getting a gain...it's not a failed design....hell for 13more hp would've put me close to 450 w/my MTI H/C set up...I sure would've ponied up another 300 on my H/C set up to reach that mark and have an intake that would've supported my forged 360 I was saving up for.

What Josey said.

Good info so far!!!!

Keith Wilson knows his ****, i bet this intake clears 20 rwhp all said and done. Key for most dyno mongers would be to shorten runners several inches to tune up max hp numbers. I plan on applying specs on this manifold to LS6 intake to reap power benefits w/out cost of new manifold. Dont judge this manifold so quickly, give it time to prove its weight. P.s New Mustang(05) kicks ***! BTW this is a major step for me to admit!

In addition to the throttle body, MAF, etc. things that the other posters have mentioned as possible reasons for the smaller improvement with a big CID motor, there is also the possibility that some porting may be required to get the best of this intake for big motors. The thing about intakes, especially intakes like the LSx style, is that they affect power in two ways: flow restriction (or lack of it), and resonant tuning effects (aka gas dynamic effects). In other words, intakes are tuning devices as well as air flow devices. And here's the thing: larger motors will cause an intake to "tune" at a lower RPM, all else being equal. There are two ways to make an intake tune to a higher RPM: shorten the runners, or increase runner cross section - either would require porting.

I'll bet people see some pretty big gains on superstrokers with this intake before its all done, but it will take a few months of experimentation by the tuners.

Remember, it's only the first day on the dyno for the intake, let's see what everyone else dyno's look like before we jump to conclusions.

I agree, have a little patience before rushing to judgment to see if this will be worth the extra $900.00 or so for big cubed and stock cubed LSX motors!!
