Lets talk Turbine size and A/R continued

Well I was just thinking your tuning is already set and a smaller change may be better.
It sounds like you are dialed in real good and that is something I wouldn't mess with.

I run a cast 478 with a 87 tw 1.10 ar as my high pressure. It spools pretty good my converter is a 3000 stall 1053

Neither.... Just SOTP. I'm not a big gauge person. I ran the 1.25 for a long time and I know how hard that turbo can pull up top. When I retired the truck from pulling I wanted faster spool on the street so I dropped to the .90. You can definitely feel the difference between the 2 housings.

Thats good enough for me as well. With the tighter housing you can almost feel the truck being held back.

I couldn't believe the top end difference when switching from a .90 to a 1.10 housing on my s475.

Hey guys, I have a question...

Can you change the housing on a vvt charger? Would doing this change drive pressure to much to allow the vvt to work?

Just curious

Thanks

Merry christmas everyone:hello:

No I ended up switching to a GT55. But I'm in the middle of dropping a 106 GT55 wheel in the PBK it has been a lot of work but it is almost done and we are going to try it on a friends truck as a atmosphere charger I have high hopes for it! Should be a beast of a charger.
