How much of a differance is between the ls6 and stock ls1 intake on my T/A??

 

stock ls1 ~310rwhp. stock ls6 ~350rwhp.

 

From my understanding the ls6 has better flowing heads, slightly larger cam, better flowing intkae manifold and of course a better tune to match the components. Vets chime in if i'm wrong.

 

I'm pretty sure he is asking how much of a gain he would get going from a ls1 intake to a ls6...not clearly stated but i believe thats what hes saying..and if so, on a stock car your looking at maybe 5hp, as you mod you'll gain more from it.

 

5HP on the Motor? 5 HP on the Wheel?

 

thats what i think he means. yes,not much on a bolt on car.



im replacing my ls6 with a FAST soon.

 

From everything ive read a LS6 intake is good for 10-15 HP provided you get a proper tune

 

I read an article in Hot Rod about a year ago that stated the ls6 intake is a 14 hp upgrade from the ls1. I think that this is reasonable on a stock or mildly modified motor. I had one on my bolt on car and feel that 14hp is about right.

 

The cam isn't much bigger. Intake will make a diff but you can get even better aftermarket for similar price ranges. The heads are what you need to be after.

 

if you gain 5 hp on the motor your going to gain the same amount at the wheels.

 

@bww3588

I think when it makes 5 HP to the wheels than it makes more than 5HP to the Motor. The Motorpower is ever higher than the wheelpower

 

10-15 hp for sure. port the throttle body and you're looking at 15-20 hp.

 

The stock LS6 was basically a completely diff. block than the ls1, it was a shorter(heighth) and the heads were completely redesigned with smaller, redesigned combustion chambers and diffrent valve angles which ultimately made more compression which equals more horsepower(explosion is much more effecient). The intake was redesigned with shorter runners and manifold floor.

LS6 > LS1 FWIW ofcourse

 

Yes. The block was machined differently. I believe a different alloy also.

 

He is clearly talking about the intake.

You will see a 5-15rwhp gain depending on other modifications.

The LS6 cam is alot bigger then you think, take a look at the lift difference!

Anyways back to the topic. LS6 intake will get you 10-15RWHP.

I have the LS6 cam installed in my motor. Actually, the only internal mod I have besides the springs. It makes a small difference but it isn't the same as the magic powersticks you can buy from the aftermarket. I guess I just view it as a small cam. I wasn't very excited about it compared to some of the other cammed cars I drove.

 

enough to actually feel a difference. maybe 8-10 hp at the wheels??

 

it is the same block in every way except internal breathing of the block. heads are same design same valve size only difference is smaller combustion chambers bigger intake runners and d shaped exhaust ports. valves are at the same angle. they use a smaller base circle cam so they have longer push rods.

 

I have one in my T/A as well and I love it. All I have for power is lid, Borla (closed up), 02 ZO6 cam, and tune. I made 360rwhp.

The cam is great if you just wanted a little bit more pep and a good daily driver. If you wanted all out power and then yes, you picked the wrong cam. But if you or I wanted to benefit from a huge cam we would need full exhaust. Right now I have my SS for a toy and a nice and quiet/smooth but peppy T/A to get me around daily.

Who are you talking to?

If you are talking about the LS6 intake getting 10-15rwhp you can feel that for sure.

If you are talking about a ZO6 cam, then we are talking about 30rwhp with a tune. If my T/A did not have the ZO6 cam and it was just lid, open Borla, and tune, I'd be lucky to hit 340rwhp. On my dyno run if I had the Borla wide open I'd bet it would be around 370rwhp (370-340 = 30rwhp).
