New Holley intake manifold..
http://www.ls1tech.com/holleyintake/holleynews.htm
our board is late :D
;)
anywas...no idea when it will be available for sale, but I hear Jan 1...but I am awaiting an email from the Holley guy...
port this manifold easy and extrude hone the thing.... should be interesting to see how much more flow this will produce after a good pigging out on the extrude hone.

Re: New Holley intake manifold.. (intel55)
seems like there are a lot of choices lately, between the superchargers, turbos, new manifolds etc... It's about time.
Just one question though, will this manifold retain more heat than the stock one?

Looks nice.
Sure not cheap.
I´ll stay with the LS6 intake........for now :)
May be a good option for a direct port NOS setup for my stroker that comes next year.

Re: New Holley intake manifold.. ('98 Six Speed)
Doesn't look like anything special at all. Maybe some more volume due to larger runners? I don't see how they could really out-do the 2001 manifold since it is the same basic design.

I look forward to what sort of gains tuners can pull with this portable intake manifold.
Those Nitrous Injector thingamabobs are VERY COOL!! Talk about an easy way to make a direct port setup!
I think there are some very cool products ahead for LS1 owners. I can't wait.

Re: New Holley intake manifold.. (LuvmyC5)
Well, my opinion is that the LS6 intake is a heck of a lot better than people give it credit for. It will be very interesting to see the results of the intake though.
I agree with the rest though. The Nitrous injectors are cool as hell!!! :cheers:

Re: New Holley intake manifold.. (C5Cemo)
I dont know what the flow results of this manifold will be when matched up to ported heads but looks to me like the LS6 Manifold is VERY restrictive for ported heads.

Re: New Holley intake manifold..
Yes, this intake will most likely retain more heat than the nylon one, but for me, I am not concerned. Been using Holley intakes like the strip dominator for years and no problems. I am wondering what these manifolds will do after being fully extrude honed. We have seen some other derivative intakes come out such as the Spyder or Hogan et al, but they have all been rather pricey and change the runner design somewhat. With our medium length runners and fully opened up to allow it to breathe would should see some good sized gains over an ls6 intake. :cheers:

Re: New Holley intake manifold.. (intel55)
This manifold has been talked about for some time now. I wonder what the delay is? How much? Maybe some performance numbers would help peek our interest even more!

Re: New Holley intake manifold..
Damn It! Just when I thought I was done! That manifold looks pretty cool, and can be port matched. Those NOSzzles look too cool also.. Aw Shucks.. more money out the window!@

Kewlbrz,
Are you sure about that flow through the intake? That seems like very nice results through an intake mani!!!
I can't wait to see the Holley intake and the results that people get, but I would not expect much. It is going to be difficult to post also. Acid porting and extrude honing is the only cheap way of doing it. You can cut it up and port it, but that is costly!
JMHO,

Re: New Holley intake manifold.. (intel55)
I like the idea of opening up the intake to accept a 85mm TB. I don't like the 20 extra lbs, the heat soak, and probably very little gains over an LS6 intake.
I'm waiting for an aftermarket composite intake that shows dyno gains on stock CID LS1/LS6's, heads/cam cars, and stroker engines.

Re: New Holley intake manifold.. (Chris@SpeedDemon)
Chris, those flow numbers were from GMHP Mag. The manifold numbers are with it coupled to the head. Optimally shouldnt the manifold not be a restriction to just head flow numbers?
