very cool numbers... would be even nicer with meth cant wait to see some final numbers after u drop pully sizes... who elce is gona start makin this IM... i bumped the RAW thread.

 

Nice temps. What where the hp/tq numbers?

 

initial tune no timing no meth just setting up a/f made 286 at 15psi

 

WAI thats crazy stuff

 

Good deal! I would go to #72s before you drop the pulley size.. ~85% Idc is about perfect. Im so glad this is finally done.. Im hoping you prove all the nay sayers about the a2a intercooler wrong..

 

I made the setup. P.M me if your intrested. AIT1 was 95 AIT2 was 108 back to back pulls I was there!!!!

 

110 on back to back pulls? I think the stock system could do that with proper cooling mods.

 

^^^^^ try 140 on back to back to back runs i was looking at the old logs just to compare them

 

With what cooling mods? Ported luminvoes(sp?)?

 

NO stock intake manifold in the world can take an AIT1 of 95 and give you an AIT2 of 108!!! I'm no mathmatician<"I think that's how you spell that?" but thats only alowing an increase of 13 degrees with a desk fan blowing on the front mount. That's amazing and has never been done in any cobalt, ever! I have also designed a liquid to air setup with a 3.5" thick bellintercooler core and yes it flows rediculous but it didn't cools as well as the air to air setup! Both are very good units. The bottom line is there is two things you need if your going to run a 2.5"M62/TVS/TURBO one is a real intake manifold cause if you have over 20,000 miles it's probably cluaged with oily soot from the crank case vent not to mention the gallon of oil sitting at the bottom of your stock intake manifold from the ill designed PCV system which doesn't work much past stock boost levels!! Another must have is a good port job, I have seen ZZP's and a few others and there great, but I take out alot more material for people with real power adders like 2.5"M62/TVS/TURBO just ask people they'll tell ya! When you can engineer parts that make a good tuner speachless your getting good at building parts!

 

If the water to air setup did not cool as well as the air to air setup, it was no properly setup. Water to air can easily out perform air to air, especially on back to back pulls.

 

I just need a couple of parts to out perform the air to air but I didn't want to open my mouth about it till I have proof. Thats how I am about these things....

 

very noob post

 

air to water yields lower iat's than air to air in a properly setup system.

 

Key word tricky phrase, "proper" the manifold and core are setup perfectly and flow more air then LSJ can handle. It's the liquid side of thangz I need to fix I'm only getting 4.5lph that core demands 10-12lph, you dig!

 

Um, 2.5 m62, air to air setup? I'll take.

 

P.M me I have a core.

 

the laminova's on the stock lsj manifold are capable of supporting 50hp each. in stock fashion.

the intake manifold in terms of air flow handles a lot more than the head is capable of flowing in stock form. you won't see an issue until 400+whp in blower applications.

 

Really? It seems like the luminova setup is restrictive.. I have no concrete evidence to support that my manifolds are better, except for dyno numbers an AIT readings from both designs compared to stock. Area you probably know more on this topic then I do, but I have seen some real significant gains supporting my design's the most significant is AIT2 being so low with the liquid to air the diff between AIT1 and 2 was 23 degrees back to back pulls at 7000 rpm's with the air to air it was 13 degrees! Thats pretty significant. This equates to lower boost pressure with higher horse power numbers on both mine and freakta's car. I have also equipt both setup's with direct injected meth. Fred is still trying to come up with a tune to account for the denser air and then he'll get in to the meth.

 

lowering iat's is fine and all. when you flat out compromise the intake manifold without any subsequent data to support your mutilation of it. this is doomed for failure.

 

Yeah... I'll just stop everyone right there.
The people that are kicking and screaming in opposition to this topic are overlooking the bigger picture.
If you all don't see it, then your obviously in over your head.

Freakta, STS2/SS... keep on doing what your doing.... this forum has been told that there is no other intercooler besides the laminovas, and apparently they will continue to believe it. The bottom line is; you've seen what the engine can do now that it's allowed to breathe... as long as it's proof enough for you, that's all that matters.

 

nothing better? sure there is. dicking with the intake manifold is the backwards way of doing it.

 

Care to put a bit more detail into that?

 

we have gone over this before

 

I forget what was said.

Either way, what I'm wondering is; are your comments directed to the fact that they used the OEM manifold? Or the idea in general of another manifold?
