Recirculaing into a big turbo

[oldschooltsi]

Has any one set up a big turbo were the blow off recirculates back into the system like the stock set up? I was wondering if that would help it spool faster. That to me seems to be the only draw backs of a large turbo that keeps me from buying one.

First, Update your car profile. Hopefully you have ALL of the supporting mods, Before you buy a bigger turbo. If not, You'll be just like almost all the other guys running big $ turbo's, And not getting out of the 13's/14's.

I have not modified any thing major on my car yet because I will masive research before hand so there is nothing to update. Turbo wise I think I will go with a bullseye set up but just wondered about the big turbos

The size of the turbo really has nothing to do w/ the BOV recircluting. If you don't want it to recirculate, correctly, get a GM and Translator or use a MAP (speed density) setup and then go ahead, and vent to the atmosphere. But w/out one of these setups, you must recirculate back to the intake or you run into problems.

Recirculating the BOV has no effect on spool since the air is only released from the BOV back into the intake tube when the throttle plate is closed under boost. When selecting a larger turbo, remember to consider what your goals are. 16G variants are excellent street units since they spool quickly (full boost at 3200-3400 RPM) and breathe fairly well up top. If your goal is to have a fairly quick spool and strong top end, consider an EVO III with proper supporting mods. If you can tolerate a slighltly later spool and even more top end, a 50 trim is also an excellent unit.

Hope that helps,

It has been said, though I have not tested it myself, recirculating (even with maft) will help keep the turbo spooled in between shifts regardless which turbo you have.

You shouldn't be worrying about a larger turbo right now as you're no where near it. I suggest that you first recirculate your BOV, then read through the tuning guide.

Bruce,

I suppose I should have been more clear in indicating that I was referring to initial spool, but that's interesting information and something I wasn't aware of.

Cheers!

Andy what's up? I knew what you meant because that's what he asked in the original post.
