Can my 6776BB spool any faster?

[87NAT]

Ever have one of those discovorys that make you smile. I think I just had one.

I just got my new Tial 38 mm Ext WG in today. (Super nice piece by the way).
My old deltagate WG that came with the ATR pipe I bought used years ago had stuck closed a few times. I have been putting off buying a new WG but I finally purchased one and when I removed my deltagate completely off the DP I was in for a suprise. The valve seat was no where near being sealed against the flange. There was a 2-3 mm gap where daylight was shining thru. It must be leaking boost like crazy. I am going to put the new Tial on in the morning and I am hoping for something good when I go to spool that big turbo up. I mean...dont get me wrong...it spools up FASTTTT now. But, if its gonna be faster...

What do you think guys....Am I going to notice a big difference?

Im curious to see what does happen. Take an incar vid, because ive been wanting to hear what one of these sound like.

I would guess there'd be a fair bit of difference if the gap really was 3mm wide leaking air.

All I can say is that I was right. It feels like I have a brand new car. The spool rate is incredible. I have been thru 2 turbos with that wastegate and I never knew what I was missing. That 6776 comes on at 1/4 throttle now and hits 10-15 psi like it was nothing! Its like its spooling all the time and is availbale at normal cruising speed. With no other changes I went from from 24 psi to spiking at 29 psi. I had to unscrew my RJC controller down about 5 turns.

So I guess I answered my own question.

How much power is that turbo capable of?

 

[PaCemkr86]

from gbodyparts.com

The best "No Compromise" turbo buick upgrade unit available. The powerfull and mid 10 proven GT6776 turbo combined with a ball bearing center section will give mild street manners and only require a 3000-3200 stall converter. Spools like no big turbo you have tried and is very street friendly to boot.If you want a proven low 10 sec turbo and street friendly manners look no further.
