Right now, she seems too like 7000 - 7200 rpm shift points best, that's where i've gotten my best ET's on the 100/150/200 shots, haven't hit both stages yet, waitin for a track rental we got coming up, and only hit the 200 at an 1/8th mile track so far.

 

See, probably wouldn't be good for me, I drive the car around on the street too much, not a daily, but I like too be able too drive her whenever I feel like it, which is often!

 

It will not make a difference as far as drivabilty.I am just trying to stress where the bennifits of a intake system like this will come into play. My 99 is still a street car and very driveable. This itake is also way to much intake for the little motor thats in that car.

Hey no offense dude and I don't want to start ****, but i'd believe in what blueballszz tells me anyday over you. He's one of my good friends and he definately knows what he's talking about, doesn't just go by internet numbers! Also, he built my motor which has less cubes than yours, less compression, runs on pump gas, and is driven on the street all the time and driven too the track, runs 9's, and then driven home, all at a raceweight of about 3500 lbs. And that was only on the 150's, haven't hit it all yet! Just figured i'd let ya know he's not just some idiot that thinks he knows what he's talkin bout and has no clue, he probably has forgotten more stuff than you even know in the first place.

And I know Nitro Dave knows his ****, that's why I asked him what he thought about it for my setup, and from the looks of his reply, he seems too be leaning toward a 90/90 for my setup, and I think that's the way i'm leaning too unless some people get some killer results out of it over a 90/90 with a setup similar too mine with 7000-7200 rpm shift points and stuff.

 

Yeah, I hear ya, i'm just tryin too find the best setup I can for the car, ya know what i'm sayin. Cuz i've had friends pick up 2 - 3 mph with a 90/90, and then other friends pick up nothing! So I just didn't know if it was worth it too get the 90/90 over my ls6/stock ported throttle body setup and when I saw this, I thought maybe if it was that much better over the 90/90 and would work with my setup, maybe i'd try this route. But i'll probably just wait around till there's some results with it and see what's up with it. With the heat soak issue, how bad would it be if the car was driven too the track and then made runs, and not trailered there, i'm assuming with a car like that, that heat soak would definately come into play, right?

 

Devon.
Yes I am leaning towards the 90/90s set up on your application.I feel that you will not see a bennifit to go to our intake with your application...

The car that I have this itake on is a stock sized bottom end with diamond pistons,arp bolts, some home ported LS6 heads and stock valves. T REX cam.. This is to much intake for it... However It still has a high 9 in it on just a 200 shot.

Yeah, that's what I was figuring from ur post. And that's pretty respectable, anywhere in the 9's ain't nothin too sneeze at!

 

I remmember when I was in high school if you ran 12s you were god.LOL
Its funny how fuel injection and technology ahs moved those times to times we could only dream about back then and be streetable.
Dave

 

good for you. sounds like your car runs decent. if you want to take advice from a guy that says this is the same thing as the aluminum holley intake, go ahead. that is a rediculous comparision.
no doubt, the 90/90 is better for your application from what I have seen. I know you don't want my 'internet' advice though.
if you care, I've had the LS1, LS6, Holley, FAST 78 and FAST 90 ported and unported on my car. all with track and dyno graphs.

 

Yeah I know, tell me bout it. The funny thing I remember from highschool was the longer you could spin ur tires from a stop and the more smoke you could make the cooler and faster ur car was, then I got into racing and spinning the tires and smokin 'em started too suck and I had too start doin **** too get her too hook! Cuz of course after I started adding power, the traction started getting worse and worse!

 

Ok call me stupid...LOL What intake are we calling a holley intake? THe alluminum for the LS1 is the weiland correct?
Dvae

 

it can be called holley/weiland/lingenfelter, they are the same thing. its just an aluminum LS6 intake.

there it is.

get the newest hot rod mag. you will see that g.m is making them for thier new ls7 also

Really its an LS1 not and ls6. But the hole heat thing, just finished dynoing our intake again, and while HOT VERY HOT yeilded the same power as if it was cold and a little better than the composite one... I should be able to post up the dyno sheets next week..
Ricky

 

one other thing, the edelbrock vic jr has a HUGE airgap between the plenum and the valley cover, this will HELP mitigate heat soak. the holley intake was essentially sitting right on the valley cover sucking in all that heat.

There is no way a LSx style intake with the massive air turns to get in the runners can match the STRAIGHT line from the plenum to the intake runner that the vic jr offers.

Here is something to munch on...

https://ls1tech.com/forums/dynamometer-results-comparisons/311005-spm-hptuners-dyno-results.html

+51 hp for the GMPP single plane intake over a LS6 intake. Best gains I've ever seen personally from LS6 to LSX 90/90 was 20-25

Also...the #7 lean issue that hurts so many LS1 pistons should be alleviated with the carb style intake too

 

When you say your intake, ur talkin about a setup like this one nitro dave made with the vic jr? I'd like too see some results, definately show us the comparison too the 90/90, give us the setup, and results cold and hot, thanks man, some results would be nice too see.

 

No we have our own LS style intake made from aluminum with nitrous injection holes already drilled tapped ready for some jets and noids.. Been working on and off with it for a couple of years now. 85mm inlet, with our 85mm throttle body. Still working to get the machine shop squared away on it, but my testing is done..
Ricky

 

You talkin bout this one? http://www.nitrousexpress.com/Pages/LS1Intake.htm

I had seen it on ur site a few times, never actually read the part there that said it was aluminum though, I just assumed it was composite like the rest.

 

The NX alum intake was a neat looking piece, and with the 85 mm size, it fits right in the middle of the fast setups.

Still intrested in how these intake setups are working on BIG ci motors, 430+.

 

that is not compatible with LS1 heads nice try
