Default LS2 Intake Worth It?

Would it be worthwhile to switch out my LS6 intake for an LS2 intake an TB?

Pointless. Even if you pick up 10 HP you'll never notice it.

ls6 intake flows better than the ls2 from my understanding.... not worth it

From my understanding and reading, the flow characteristics are very similar between the two intakes, but in a FI application, the extra 12mm opening is simply not going to make that big of a difference.

I went with the LS2 because I already had the 90mm TB and the LS2 intakes are cheap. Plenty of power has been made with the LS6

I got my ls2 from BLOWNBLUEZ06 and he ported it for me, it looked great. By what he told me the ls2 will do more for you on the top end.

While I did go to an LS2, I also uped my block size. With my previous 347, I made plenty of power with the LS6...

I got a ls2 manifold as well from bret(BLOWNBLUEZ06 ) I am installing it once i get back from deployment. From what I have readis 50/50 some say ls6 some say ls2. I like the fact that 90mm TB will give you a better throtle response for FI. I was going to get the ls6 with the 90MM TB but I was not sure if that would hold high boost for my future build.

Does anyone know the runner lengths and the plenum volume for both intakes?

In this article: http://www.vetteweb.com/tech/vemp_08...w_testing.html

They say "In forced-induction applications, the ported LS2 manifold consistently outperforms the LS6 and the popular aftermarket intakes during our test sessions," says Incaudo.

I'd do it if it was free. Otherwise, I don't see much value in it for FI.

I think for all out a 90mm is needed. Maybe not at 700rwh

That isn't in dispute. The question was is upgrading from an LS6 to an LS2 intake/TB worthwhile.. Given the cost I don't think so.

I'm considering this mod for next season but from what I have read the intake apparently is prone to leaking on the inside due to the friction welding process.

Apparently it doesn't make a difference with boost but I'm wondering if it affects the distribution of air in each cylinder.

I'm still leaning towards using the TPIS 90mm LS6 intake
