Check out this new style Intake manafold!
#225
I'm gonna be honest, I have no idea. More flow is never a bad thing, and the fastest lsx powered car (paul major's vette) is running a manafold with a very large plenum and a relativly short runner.... that being what it is I think it would work, but I know when you are pressurizing the intake like FI does, you can get away with intakes and whatnot that are not as great, hell guys go so much farther with an ls6 intake then you ever could with an n/a or nitrous application it's not even funny.
Will the intake help an FI car, I'm sure it will... just don't know how much or where in the powerband.
Anubis I think you're a prime candidate for this intake, you'd probably see a really good gain from 6000 rpm up, might lose something down low, but that's traction control for the street

They are closing the damn track for 2 weeks after Saturday. I probably wont get mine on until Monday or Tuesday. Gonna have to wait a couple weeks for some track times. We were gonna put this one on the engine dyno to do a head to head comparison but I found out that my FAST intake is completely melted on the inside of #8 runner so I need it on the car now. This is my daily driver so I cant have it down for too long. The one with the direct port wont be here for a couple of weeks due to the holidays. Not sure if the timing will work out for the engine dyno on that one but we hope tol have back to back chassis dyno info on the same vehicle.

On an FI setup, it could probably hurt you as increasing the volume of the plenum and runners may cause a problem with pressure. Mighty Mouse just went 8.7x if memory serves with a stock ported TB and LS6 intake. So it's definetly a different ballgame.
It better produce gains over 7K on an NA/N2O setup. FAST is usually flat after 6500.

I have to agree with everything here.

I would like to see it pull and gain as high as it wants! lol.
JL ws-6, I assume you were talking about the short runner variety for me.

If it werent for the torque falling off, I would swear that was a Cobra graph. What cam are you using?

I've read most of this post and you guys have lost me... Help me understand the basics behind let's say build objectives for Torque under 6K rpm, and over 6K if racing/HP is your goal, as it relates to intake design. I've always thought long runners like in a Tunnel Ram and the Victor Carb. intakes were always for high rpm applications, and short runners like an LT1 manifold were better for Torque? This thread seems to be flipping that?
My LSX 440 (4.125/4.125, L92 Heads and TSP Torquer Cam) will be ready next month and I'm looking for a good intake match. Objective is for the motor to be mostly done by 6K. I really like the looks of this intake and most Sheet Metal variety intakes, but always read how they're for high RPM, boosted applications only. Current plan is a FAST 90/90, but would like to hear how this intake would work for what I'm looking for.
Thanks,
Charlie

unless ofcourse your spraying.

So would the forthcoming long runner version discussed here be a potential for me vs the 90/90? I really like the way this manifold looks, along with the price being pretty righteous. I might be being a bit conservative on the rpm objectives I stated, but I am definitely more interested in torque vs a car to win at the track.

It's going in a 3600 lb car that will never see the track or be in a race over 90 mph, so I'm not interested in how fast I can go @ 7000 rpm. Torque gets you going, HP gets you there. I'm focused on the getting going, which is why it's a 4.125 stroke, non-nitrous, NA motor. Since when is torque not usable on the street?

Also, if you are building a 440 that you aren't gonna race, then it's pretty much for show and this intake just looks better.

ok what about me...i think my cam has been spec'd for the short-runner version (that i have yet to order), but i was wondering if the long-runner would be the right one for me? motor is a 4.185x4.125 ~11:1 hydraulic roller pump gas TFS-245 headed LSX motor. cam specs are "in the mail" still...but i'd like to spin the motor up around 7K-7500 so i can keep my 4.11's in the rear (M6 car w/9"). long runner will produce more torque down low, right? so i should stick with the short-runner since i have sheer cubic inches on my side for the low-end power. the car is a street/strip car, mostly show-n-go. no serious racing, not a daily driver...etc...

Also, I can tell you that the combo that I have been working on with the solid roller and 245 TFS heads makes very little vacuum. If throttle response is what you are after, make sure you get a smallish cam or you will have tuning nightmares.

Getting that much torque down on the street will require lots of suspension work...
I chased the quarter mile clock with my Turbo Regal, lots of fun, but it was a never-ending pursuit of rub money here, rub money there, go a little faster. It's now more rewarding to scare the wife and entertain the kids in between stoplights. :-)
So... what version should I get, current version or wait for the longer runners?
