5700rpm is not right. thats way to laggy for a 35r

i have a gtx3576r with the t3 .63ar hotside running on a stock 2.0 f20c and i get full spool of 12psi bu about 4,600 rpm. This is with a track forged sidwinder manifold. I know i dont have a standard 82mm wheel gt3582r but i doubt that it should spool that much slower than mine.

Here is my boost plot. This was on a 4th gear pull.

 

^Benton, are you using a solenoid to regulate boost pressure or are you on the wastegate?

 

Had a bit of help tbh from what I can see/read full boost of 20 psi at around 5700 rpm is about right. My exhaust isn't restrictive and I run a screamer pipe - not that that will help massively.

I seen another car on the dyno with a pretty damn similar setup, a Kings performance 6262 precision turbo setup and the spool between both cars was roughly the same.

I've played with the tables and it appeared in some logs I managed to drop the full spooled point by around 200 rpm but on a different run with the same boost it went back to normal I suspect temperature plays part in this.

When the turbo fully spools it comes in with a lot more conviction and spins the wheels easier unfortunately had rubbish weather and haven't been able to do any more testing/tweaking.

Gtx is bound to help spool for sure, I'm sure that was one of garretts motives from I read.

Joey is running more boost than me but he said when his car was rough the same as mine it spooled around the same point.

I just don't know.

 

That spool time wouldn't surprise me since you run a twin scroll and log manifold but that's damn good figures.

 

I'm running a 7psi spring in the wastegate and the boost is controlled with a 3 port Mac boost solenoid via the aem v2

 

Just an update to this spent a hell of a lot time and managed to get it fully spooled at 5200 rpm does this sound better?

I think I could lower it down even more say 100 rpm but with a hell of a lot time spent and lots of road runs.

Hard to keep spool good, not over boost or oscillate and not come in with a thump as spins tyres easily.
