no gain with bbk ssi intake????????????? hey guys i finished my intake swap about a month ago and i took it to the track and drove it for a few days and it dont really feel like i gained any thing if any thing it feels a little weaker down low.
also the car seems to be running rich the exhaust smells like fuel and the plugs look darker than they normally do.
ill put a fresh set of tr55's about every 12-15k miles and i pulled a few of em just to take a look and they was darker.
the car had a full tune when i put my lt's on and the exhaust dident smell like fuel seemed to run cleaner so i dont know if the intake made it go rich.
before the swap i has a ls1 intake.
let me know what your thought are.

well, on these cars you dont really feel 5-6 hp gain, its not a bike
i have put in intake and exhaust on my car and didnt feel any gain. you only feel the gain after lt's, gears or a stall, or some internal engine work imo...

very possible you only gained a few hp.
wouldn't really surprise me, i haven't seen much honest proof that the alum intakes make the same power as the LS6.
but rest assured you'll get more heat soak and add more weight to the engine

Everyone has their opinions on intakes in one of the LS1/LS6 performance books they ran it on the dyno and picked up a noticable amount of power over a LS1 manifold. The only way to know is to dyno before and after with a tune. I have a Weiand/Lingenfelter on my turbo car, people said their crap, don't add power, etc I couldn't notice a difference in power but I did have to add fuel to bring my AFR's down. So if I'm adding fuel it means it's flowing more air for the same amount of boost.
Also has heat soak ever been proven? Has there been any IAT's taken at the intake port composite vs aluminum?

ya the heat soak thing is a joke. would be a diff story if this was a TBI motor. the air moves through the Intake fast enough it doesnt have time to heat way up.
One thing i might note about this intake though is to make sure the underside plate of the BBK is sealed good. after i installed mine on my s10 i didnt notice any change. after a few weeks of driving i got my dynotune and we noticed power was down. turned out the screws on the under side came loose? and that gasket was leaking. resealed the underside and loctited those little screws in, picked up 40hp over my leaking intake pull. didnt have a before install dyno so i cant tell you what i actually picked up

maybe the one my friend had was a lingenfelter. Im not sure if he had it retuned after the ls1 intake swap but i believe his car actually ran slower at the track with it.

sounds like a problem with the install, if you still have the MAF than I don't know how it can run rich. Also you said you took it to the track and it doesn't feel faster? What are your before and after times? Dyno-Proven GM LS1 thru LS7 Performance Parts book the picked up 27hp and 22ft lbs of torque over a LS1 manifold with heads, cam, exhaust.

LOL, now thats funny.
I love people who hate on metal intakes, it's comical. I'm thinking most people who swapped intakes & say they saw no difference need the driver mod to begin with in most cases. So of coarse your probably not gonna notice a difference. And a intake swap won't give you the seat of the pants feeling some other mods will.
My buddy threw one on his H/C Camaro & picked up a few tenths & some MPH here at TRP on a hot summer day with the intake being the only part swapped. So I know for a fact without a doubt these intakes will make power. I also know that the widely hated Weiand intake will make power too in the right application, even N/A.

well i have experience with both i installed the weiand on a buddys 99 camaro, it gained absolutely niothing on the dyno i think it was 2hp. a4 so no variables,
and then a buddy swapped his 02 ls6 intake for a bbk, and gained 4hp, then had it ported for a whopping 10hp more, so yes i have experience and they are
junk, and sya they dont heat up is a lie try working on one 2hrs after the cars off youll still burn your hand vs a composite...
the original poster, sell it and get a used ls6

Where did anyone say they dont heat up? No one did. But heak soak is over rated by people who know nothing about how it actually works. Your not gonna have heat soak issues while the car is being driven. The air moves thru the intake & into the heads WAY too fast to heat up from the intake.
For christ sake you could argue the heads are also heat soaking & robbing HP too, how bout we do that now??
I'm not sure why you had shitty results but I have personally witness the opposite. So you run a LS6 if you want but other intakes will make just as much if not more power. Granted you might need to do a little porting but thats the beauty of a Aluminum intake, porting & port matching are very easy & can result in HP gains.
This whole everyone being anti Aluminum thing is funny. But yet everyone crys about their composite exploding during a nitrous backfire. So there are strengths & weaknesses to every intake.

Yeah, and a Super Victor doesn't make any power on a 408-427 either
