It was very straightforward. It was made easy thanks to jMx's how-to on ls1.fbody.com and a post by EHS and c4c5specialist on the other C5 forum. It only took me about an hour and a half taking my time. I also found some dead lady bug carcasses and lots of dirt and leaf remnants in the intake valley which I vaccumed up with my shopvac. Very interesting finding was that the intake port on the passenger's side cylinder head next to the PVC valve on the TB was stained with a lot of oil as compared to the all the other ports. I'm definately getting blowby. :(

Now, onto the performance. Did the idle relearn and took her for a spin (35 degrees Farenheit out). It PULLS HARD! It was going to bust crazy loose on the 1st to 2nd shift so I eased up and got traction and floored it again. I'm ecstatic with the results. I didn't expect that much of a SOTP response. It's a definate must do IMO. Maybe my car needed that LS6 intake more than it thought! Next up, T1 Cam :eek:, ASP pulley, ARE oil pump and LS1 Edit tuning :smash:

Congrats,
Fun stuff, this do it yourself moding!
I love it when a plan comes together!

 

Levi!!! That kicks butt!!! Now ya got me sold! I have to do it..

 

Sounds great - I wonder what the actual increase in HP is? Anyone know? What about the Edlebrock - it's aluminum and looks like you could polish it up for a cool look.

:cool: :cheers: :D

Wow only an hour and a half? :eek: I really want to buy one but am affraid I'd get in over my head. What's a good price for one? Where did you get it? Can you see a difference in ports size from the LS1 intake? Thanks for the inspireing post!

 

:cool: Did you any port matching with gasket?

 

C54TIM, Thanks :cheers:

chuckster, I never thought I would feel that much of a difference. Maybe mine is a freak but it seems to LOVE that intake!

fxrhm, the actual RPM increase is usually 7-10 RWHP. I think that the Holley intake is a very bad idea. Sure you can port it out for very little gains on a stock cubed motor and take a chance of getting something if anything on a large cubed motor. Also, 10 minutes after you fire up the car you have a heat soaked manifold. This gives you a hotter air charge which makes you more susceptible to detonation so you car pulls timing to avoid KR, etc. I believe it defeats the whole purpose. All of the major tuner use the LS6 intake on their stroker motors, etc. The only person I know of that swapped to a custom sheetmetal intake was SW. I think for streetable and daily driven LS1's the LS6 intake is the ULTIMATE setup for the time being. Proven gains and no heat soak! :yesnod:

The One, thanks man!

QuickSilver97, if you're comfortable with a wrench then you'll have no problem. Just follow that write up by jMx on his site, http://ls1.fbody.com and the post by EHS on the other forum. IM me if you want the link :), it has some great tips from c4c5specialist :). I got mine used off of ebay for $399 and then I bought the two rear crossover plugs and one coolant crossover pipe for $20. Typically the intakes are $430 new (you'd better get one now as there will be a big price increase by GM for all it's LS1 products across the board) + $20 for the two rear coolant plugs and one crossover pipe. BTW, don't let people sway you and say that you're harming your engine with the two rear coolant plugs. This is how all '01+ LS1's are set up so you're good to go :). If you go to jMx's site listed above you'll see the greatest difference b/w the two intakes and that being the lowered and flattened plenum of the LS6 intake. This increases the volume of air that can be pulled in. There's a great picture of it on his site, check it out :) I think this is a no brainer for your ride. I think you'd be very pleased with the outcome!

jawski, nope, no port matching at this point. That will come later when I do heads :D


If anyone has any questions about the install I will help. It's really pretty easy!

Thanks Levi! I'm gonna go for it!

 

Do you have the GM part# for the manifold? :cheers:

 

Levi, I agree with you about the Aluminum intake.. Heat soak sucks.... :smash:

Since the composite intake is already heat resistant just take it to be powder coated. They make a chrome like finish. Can't cost too much...

 

Congrats Levi! Your results sound impressive.

I got 4 Hp and 4 Tq on the dyno from my swap to an '01 manifold.

 

I know there's more than 4HP and 4TQ gained on mine :eek: :D :D :D :D :yesnod: Mine is a freak with this intake on. I have never felt such an improvement besides nitrous :). Thanks for the compliments Cemo :)

 

Ooops...my last post was a little brief. I agree, your swap could be worth more than 4 and 4. All of the little problems you fixed while doing the job might be worth that. Are you gonna get some dyno numbers or track times sometime soon? I'm interested in your results. Your mod list grows everytime I see it :cheers:

I didn't notice any real SOTP change after my manifold swap....certainly nothing like yours.

Congrats again!

 

C5Noir:

Glad it worked out, and "as advertised." I had the same reaction, SOTP more torque. As you know, I also added the BBK 80mm TB, and after two weeks, no codes, no problems.

My post is still on the "other forum," but the pictures are gone, thanks to the ongoing "love fest" between C5F and CF. I get tired of having to post everything twice because we all can't just "get along."

Here's the link from this forum:

I found two things important:

1. Use c4c5specialist, or else be sure to do it by the book and don't try to "improve things" and "free lance" changes.

2. Especially, don't mess with the factory BBK TB settings. It will idle just fine, let the PCM relearn, and you are good to go.

Again, always glad to get positive feedback.

 

Cemo, yes, I'll get some new N/A times when the track opens up in two weeks ;).

EHS, I can't thank you enough for those pics. I'm glad I saw them before they turned into red x's. BTW, could you zip those up and send them to my e-mail sometime so I could show them to others for reference some time. I concur, c4c5 is the MAN! I can't thank everyone enough for getting me squared away! Thanks, I owe it to the help of you all :cheers:

 

We dynoed the new released LS6 manifold an a 2000 car and the results were 17hp and 11trq. The car had a Blackwing intake and exhaust for mods. Throttle response is improved also with the new manifold.
We feel the Holley aluminum manifold is not worth the extra money over the LS6 manifold. We have heard of other companies dynoing the Holley in comparison to the LS6, there were no gains at all, none! Plus, heat soak is an viable issue with aluminum intake. Thanks,

Nate

 

Those really are impressive numbers, Nate.

Have you seen substaintially different results between the new and old versions? I'm starting to wonder about "the fix" :confused:

Thanks

 

Nate, I'm willing to bet I got about the same gains. I'm VERY IMPRESSED with how it performs now! I love it. :smash:

 

Levi- which year model manifold do you have?
