He can also spray nitrous in the lower rpms to get the turbo spooled

As big as his turbo is, it can't really spool too much sooner (as in not like 1000rpm sooner or anything) than it is without having some serious surging issues. That's just the nature of a big turbo like this. On the other hand though, with a slightly smaller turbine (stage 5 T350) and larger a/r T3 housing, spool could probably be improved a bit without hurting overall power too much.

Torque is not as bad as I thought, might do 550 at the wheels - we'll see.

I know its laggy - but I will get it down to 4300 or so.
Also - this setup will run 25 psi opn pump gas ALL DAY LONG - egt's are NOTHING.
I will shoot for 500 at the wheels on pump gas.
If you are ale to get 500 at the wheels on pump, then you should have no problem getting over 600 at the wheels with race gas.

Rememberiung you're previous set-up, you hit 397 (or so) at the wheels on 19psi on pump, yet achieved 574 at the wheels with race gas and 24-25ps, no hardware chagesi. So, gaining so much power with that crazy advanced timing of you'res, i would not be suprised if you get 650-680 at the wheels on race gas and you are aiming to run over 25psi on race gas as well right?

oh, going real OT, just found this great youtube vid on a modern 1.4L TSI engine dualcharging system..

It's going to be expensive to replace that water pump!

I'll have the videos soon.
Sunoco 2 miles from my house just started selling 100 at the pump, life is good.

The owner says to me, "we sell to Fahrenbacher/Lowles"
I said, "oh, that means you have to deal with Spencer, sorry to hear that"
He says, "Spencer's not THAAAAAT bad......"

Some of you local guys know go-go "sunglasses" Spencer.
