T28 A/R options...

[Jspeed17]

Has anyone with a GT2860 or larger turbo on their MSP experimented with different turbine A/R's? Most i've heard is that the recommendation is the .64 A/R is the one to go with for more immediate power earlier in RPM's. But why not .86 A/R??? Will it spool too late in our cars???

Reason i'm asking is i've found a great deal on a .86 A/R Disco Potato....tempting

i've run a .64 and a .86 28rs on my car. The .64 is more fun for a daily car. 505 zoom runs a .86

More top end HP on the .86 right? These just seem to pop up everywhere on the web, maybe because of the SR20 crowd that uses them?

yep definitely more top end oriented.
