does synthetic give more HP?

A well-designed turbo system doesn't exhibit turbo lag. The problem is, most of the turbo systems in cars a decade ago weren't well-designed, so everyone thought that any turbo system had lag.

Based on what I know about cars (admittedly little, but I do read the 5 million oil threads that pop up here) I'd say the difference would be negligible - less than 1%. You will never notice.

Well, you will still have some transient boost lag and definite some normal spool lag with a more powerful turbo. There's a lot of things you can do to move the boost curve up or down on your engine.

Personally, my tiny little T25 hairdryer is a non-ball bearing and has a normal transient lag (about a second or so) but it hits full boost (15psi) at 2700rpm. VW 1.8Ts hit max torque at around 1950rpm. The EVO rips like a bat out of hell at around 3000-3500rpm.

EDIT: Synth oil doesn't more HP over already being properly lubricated. But it does help the turbo's bearings from coking.

In our dragster, we synthetic tranny fluid (amsoil) but we just use regular oil in the motor because it's changed every two weeks which is expensive to begin with. Synthetic for us just makes the tranny run cooler. It's a powerglide and it takes a lot of abuse running 8.30's with a small block. It also reduces the wear in the tranny.

Yikes, that's a quick spool if youre at 15 by 2700. I have the ballbearing t25 running (reportedly) at a mere 6.something psi from the factory and there is almost zilch noticeable lag - specifics forthcoming as soon as I can get a !$!% boostgauge in there...
