And body do a Boosted app then dyno it then put a ls6 intake and dyno? How much of a gain is there from just going to a ls6 intake? I feeling this might be another soon to be mod.

LS6 intake = $350-400 for some gain.
Tuning = $400-500 for BIG gains.

not always

if you can't flow anymore w/ the old manifold, tuning gets you now where <img src="images/icons/smile.gif" border="0">





upper RPM is the thing to look at

true, but i see the "adjusted WOT timing curve"

i still say tuning first, LS6 intake second. dont wait a year for LS1-edit ('98) to come out.

yes, but see the dip in the bottom curve at about 4200 there's your adjustment.

there are no changes in the advance in the part of the curve where the manifold comes into play.

I have the logs to show the increase in flow from the manifold <img src="images/icons/smile.gif" border="0">

Thats what I keep thinking...the ls6 intake would help FI cars out over 4500 rpms where you can really feel it nosedive

RyanJ

oh dont doubt the flow of the intake...escpecially in an FI app. but if i had $400 and a barely idling, non-tuned twin turbo, the PCM would already be in the mail.

lol how you read that graph. Oh i'll do the programming first but just wondering if it was worth it.

Since my engine is already out of the car, I'm getting a used LS6 intake just for convenience sake, figuring it's easier now than later, and an ything that will help flow better will decrease boost a bit and save my engine... I'm getting the PCM done as well, once everything else is together in the car.

Also, doesn't something need to be ground down to allow the LS6 intake to fit?

Correct me if I'm wrong.. but torque and detonation is what kills motors. Boost will only provide enough pressure to lift heads and pop gaskets.

just me

Harlan,
Are you still using the stock cam and making that kind of power?

I ask as I may just detune my motor and go back to the stock ls1 cam.

yes steve, stock heads and cam

detonation kills motors. the increase in cylinder pressure from detonation is what lifts the heads and pops gaskets. extreme boost will do it, but then you have other worries.
