I am thinking of ways to make my custom turbo setup better. I do not have any real issues with how it runs, not sure if it is as strong as it could be though.
I do not have velocity stacks in the intercooler right now. I have a extra intercooler that I just picked up that I want to try a few things.
I did some quick research on Velocity stacks with turbos. From what i can tell there is a benefit to having them. They are suppose to be able to make the bottom end torque much better. And a longer stack makes more low end torque and with a turbo it doesn't matter if on the top because the turbo will pack the air in at high rpm.
So here is my question for those who have experience. What size of Velocity stacks would be a good starting point. I want to make the sled better off boost. I don't want to leave anything on the table.

Interesting that no one responded. I had the same thoughts as you.
Not sure if this helps but on the Cannondale Single 450cc running short gives 1-2hp on top but does produce a dip in power right about 5000rpm.Short is 1in tall and tall is 3in tall.There is also a formula for figuring out the best radius and with that we gained another 1/2hp and improved the dip alot.Will look around for the formula.Here is some more formulas.Not one I am looking for though.

When I built my intercooler I made my stacks stick into the plenum about 3/4 inch with about 3/8 inch larger diameter bell on the inside. It seems to have plenty of bottom end power. Ken....
