spool time on a .63 exhaust

Got my new turbo today, a m27 .48 compressor .63 exhaust. Looking for a idea on the spool time for my D16A1. Looking for top end power

Re: spool time on a .63 exhaust

Prob.ly 5K ish but there are a lot more things that could effect spool up time

5k-ish is cool, I can rev to 7.5k. I'll be using a 2.5 exhaust turbo back if it helps to mention.

Re: spool time on a .63 exhaust

run a 2 1/4 in. dp it will help spool time ... id say 4800-5200 leaning more towards 4800 though full boost 10 lbs

Re: spool time on a .63 exhaust

Ive got ~15psi on my t3 60/63 on a lower compression d16z6....by 3500rpm... 3in DP right off turbo. Honestly... its suprised me alot.

Say I floor the car in 4th gear at 2500rpm... i have over 10psi just past 3k.

Re: spool time on a .63 exhaust

hmm, what compression? I'm gonna be running custom weisco 9.1:1 pistons for a closer to normal compression (9.5:1) for my normal driving & low to mid power.

Re: spool time on a .63 exhaust

Compression is going to have next to zero effect on spool time.

Most of the spool time is going to be due to manifold design, and tune.

I had a .60 trim T3 with .48 turbine that spooled at 2500 rpms on my LS. Swapping to the .63 housing, and adding a very large 24X11X4" FMIC, I spooled at 3000 rpms. Whoopty-----, 500 rpm difference... keep in mind we are still dealing with tiny OEM "stage 1" turbine wheel.
