The Metal Intake Thread...
Heat is not an issue. As I stated earlier, It gets hot as hell here in south Texas as you know. Sure when its parked with the motor off, yes it gets as hot as the motor. But as soon as you drive it for a couple of mins its cooled off. This summer I drove for 45mins, 98* outside as soon as I got home and parked the car I lifted the hood and put my hand on the intake and it was just barely warm to the touch. Not hot at all.. 
i have to disagree with heat not being a issue and/or the way the metal weiand intake flows. i recently did a top end rebuild and a weiand intake was part of that. the cam i went with was an f-13, ported and polished heads with 2.02's, 1.60's and 918's. type r lifters and harland adjustables. we went as far as port matching the intake to match the heads and opening the inlet to 80mm to match the 80mm bbk. l/t's with no cats, x-pipe and true duals.
with the weiand, the mid range to top end of the car was terrible to say the least. the best it ran was right after start-up when the motor was its coolest. my intake stayed extreamly hot to the touch both while running and after shut off. i was very disappointed in the metal intake to say the very least.
we recently switched to a Formato ported ls2 intake and a ptm t/b (90/90)set-up. the mid range and top end are awesome now. exactly what i was looking for with this type h/c. i was not sure what to expect with the intake swap, but i am extreamly happy with the results.
not trying to step on any toes or other opinions with all this info. just telling my story and giving my own 2 cents.

i never even bothered to make a pull with the weiand. as i said, i was very disappointed in the way it ran to say the very least and i dint need a dyno to tell me that. however, if i had known what a difference the ls2 intake would make compared to the aluminum, i would have made a few pulls to document the difference. the intake was nice to look at being polished, but it just wasnt performance wise what i wanted.
I understand that you were just giving your story and all, but how can you say how a specific intake performed over another without track, flow or dyno numbers? Im not saying that what youre saying is bs, but "seat of the pants" feel doesnt cut it as each person's "seat of the pants feel" is different from one person to another. I mean for example, I had a friend put a filter on his car and after putting it on, he claimed it felt faster...Well to make a long story short, he only picked up a couple hundredths - which honestly is something I couldnt really feel.

Verdad Gallardo i can appreciate your concern for my questionable ability to tell weather a vehicle is running better or not. however, i am 45 years old, been driving since i was 12 and cant even begin to tell you how many different types and kinds of vehicles i have owned and/or driven. if i dont know by now if a car is running good, bad, better, worse or somewhere in between, then i would be best off letting one of my kids drive me around.
MY opinion on the intake was the fact that there was a noticable difference in the performance of MY car. I used the same maf, fuel rails and injectors on both intakes and there was just a huge (not slight) difference in the way MY car drove. I drove it in the rain, sun, night time, day time, cool weather and hot. MY car just drove different.

wasn't interogating (sp) just wanted to know all the facts as i have a weiand that will be port matched as well, but i will be using a 85mm. i just dont understand how THE MANIFOLD could make it run terrible. i would be intersted if the manifold made it run worse than the stock one or it just couldnt flow for your app. maybe you flow so much you need a gmmp metal intake 
On bbk's website it says that the ssi flows 15% better than the ls6. The weiand intake I am not able to find anything that says it flows better than or equal to an ls6 intake. I am looking to get a metal intake for the simple fact that if I have a nitrous backfire I will still be able to drive my car. Anyone able to show some graphs? This would be helpful. I was able to find a new weiand intake from a sponsor on here around the 350 range, but the bbk was a different story, 500 was the only price I could find.
im very happy with my weiand.the heat soak is retarded and plastic is so ugly.cars ran metal intakes from the get go.as far as the power goes over the stock ls1 the weiand made a nice sop difference.it is a metal version of the ls6 ill say it once more heat soak is bs
Im not worried about heat soak. I'm worried about performance. The cost of bbk is almost 500 where as the ls6 is 400-440 and the weiand I found for 370. You know the "you get what you pay for" saying, just trying to make sure the weiand is undervalued. I am looking for a graph of a ls1 to weiand dyno graph to see the improvements.
Well I have preliminary Dyno numbers on mine and my new motor... I made 690rwhp/640rwtq at 5300rpm at 16psi of boost....11.8/1 AFR and 16degs timing, air temp was 84 degs and 85% humidity
. I had and idler bearing go bad after about 6 low rpm tuning pulls and during the last pull and broke my belt.. New idlers are on, just waiting for some dyno time..Maybe this week or next week. I will post the final dyno run with the final tune and more timing...
Should hit 750rwhp pretty easy..

Last pull was720rwhp/650rwtq at 17psi and 14degs timing stopping the pull at 5700rpm. I'm still working on a high rpm miss. Starts to miss at about 5600rpm. I replaced the valve springs yesterday and went to a NGK colder TR-8 plug. Hope to get back to the dyno next week some time...
Final dyno today.. Low boost at 13psi was the 693 and high boost was the 832 at 17-18psi...3.25" pulley and 8" overdrive balancer.. Still having some possible belt slip above 6000rpm...
