Engines are way to dynamic to rate intake manifolds by flow bench results.

 

Richard covered that real world testing at the track and dyno could yield different results. I seem to recall that someone recently on here picked up .4 secs in the 1/4 with a regular LS1 intake swap which flows less than the truck on the flowbench. Reguardless, it is still good info. The flowbench can't measure the total flow of 8 runners and the change in dynamics as rpms increase. An intake works as a harmonius unit rather than an idividual runner like a head can be measured.

 

so whats the diif in the truck intake with the stock tb and the ssr with its stock tb. how much does the smaller tb affect the intake over the 90mm and the ssr it could make a huge diffrence in flow right?

 

Trey is correct to a point. Still there is some relavent info in comparing the intakes. Remember these manifolds are run dry and the dynamics are different than a wet intake.
I've been thinking about making an adapter to mount the intakes directly to the flow bench bore. That would eliminate the port and would let us get a better look at net runner flow. Now........all I need is time...............

Get to work Richard

You too Grip

Thanks for the comparison. Do you think there is any way you can get your hands on a FAST intake?

 

this is deffinatly good info keep up the good work.

 

I thought it was a LS6 intake??? I could be wrong??

 

Kano has an LS6 intake on his truck. The LS1 is a little less efficient as seen on th eflow chart.

 

And Kano is also the one that gained 4 tenths in the 1/4???
