Ligenfelter intake manifold Well I thought for 250.00 I was getting a hell of a deal
and that I would see an increase in performance over
my LS-1 intake.
Something isn't right. My car has slowed down .3 and
I've lost 2 to 2-1/2 mph. The alum intake has not been ported
and someone at the track said he heard that it flowed less
than the LS-1 intake.
I've got HPTuners coming this week (I hope) and maybe it can
tell me if there is a leak or I just plane need a tune.
My wife isn't going to let me spend anymore money on the
car this year so if I have to I'll put the LS-1 intake back on.
I'm just not happy, I had high hopes when I installed the intake.

I dont understand the market for these pieces. Unless you just want more bling.
The advertisment plainly says its a LS6 style intake but made from aluminum. You are paying for looks.

Well, I didn't pay anything for looks at 250. and I haven't seen
an LS-6 intake for that cheap and that is why I bought it.
I figured I could ice it down just like the LT-1 guys.
But there was no noticable increase in power like I was expecting
with my mods.
I've also been throwing a MAP code since the install. Is that
a sign of an air leak? I've got HPTuners coming in a few days
maybe some tuning will help? I'm about ready to put my LS-1
intake back on.

probably a stupid question but did you re-check all your connections, make sure all your sensors are plugged back in ?
You could put the LS1 intake back on and if the car goes back to the way it was then you'll know for sure it was the intake. If you could sell it for what you paid or close save that money towards an LS6 intake for next year.
just my .02

Plastic manifolds do run cooler but realistically are far cheaper to produce. Cant remember the last time I saw a "Fabricated Sheet Plastic" manifold either. In the old days we would spray a little ether around the intake a listen for the motors idle change looking for leaks.

F.I. cars don't have the benefit of the natural cooling process of fuel vaporizing in the carb venturi. Also, after talking from our FAST rep, the reason plastic intakes aren't more popular in the aftermarket is because of the high tooling costs associated with creating them. It still all comes down to physics though. I can hot lap my car 6-8 times at the track with a composite intake with NO loss in performance. Try that with an LT1. I also picked up 22 RWHP going from an LS6/stock ported TB to FAST 90/NW 90 setup with NO other changes. Talk about bang for the buck. 481 HP 423 TQ.

How about some discussion on this - I still haven't seen anything proven on this, even after all the hot air that's been exchanged here on the board, haha.
For the sake of argument, let's say air moving at >3000RPM through the intake was heated 10 degrees, from TB to cylinder - while moving at 600+feet per second, with most of it not making contact with the intake itself. (That temp increase is probably stretching it bigtime, in reality I'd guess it to be closer to 3-5 degrees F, or maybe even a negligable change in temp ?).
How much horsepower is lost in a 10 degree IAT change ? What about the (probably) more realistic 3-5 degrees ?
It's a given that cooler air = more HP due to the higher concentration of O2 in the mixture, but I don't think the air is in the intake long enough to be heated to the point of costing a large amount of hp.
It's pretty clear that there's a 0hp loss with a composite intake where there is SOME as-yet unmeasured loss with a heat-soaked aluminum intake - so the decision should be a no-brainer... However I don't think the losses are as big as people make them out to be... Practically every car on the road besides the LS1 has a iron or aluminum intake.
