turbo spool

the turbo on our truck doesnt seem to spool right. when its stock it will maybe hit 10lbs. edge evo tow haul and it does alright hits 15 around 2600rpm gets a little more higher the rpm. i dont know what might be wrong but this just doesnt seem right the turbo has the wicked wheel compressor on it. im not sure what all else i need to mention so any questions shoot. anyways help me figure it out.

yes, they are called donut's. they get sandwiched between the collectors. when you lay under your truck you will see them, they have 2 bolts around them.

You might check all of your clamps at the rubber connections too. A loose clamp can cause a boost leak.

You might also consider a boost controller - like one from www.rjcracing.com. It's a simple grainger valve set up, but man boost can come up quick.

ps. this unit works for a wide variety of turbo engines.

Im thinking about welding those up-pipes on my truck right to the collector. Seriously, if i take those things and they leak in 10K im gonna be a bit pissed, and welding them is cheaper..

If you weld them, there's not wiggle room when installing the turbo, and you don't leave room for expansion of the pipes.
