Benita,

  Thanks for your response...........I have one m= ore question.........Can you tell me

why the F1-68 (Larger diameter) turbine wheel would be= less likely to over-speed

at altitude  using the 1.15 a/r housing than the = F1-65 turbine wheel ?........... In my

mind the F1-65 wheel would seem to be a "looser" fit i= n the housing and probably

bypass more of the exhaust..............I admit to bei= ng neophyte at this.............

 

Thanks Again,

Kelly Troyer

-------------- Original = message from Benita Betancourt <bbetancourt@turboneticsinc.com>: ----= ----------

Kelly,

Your only option with the 1.15 a/r is the t4 turbine h= ousing in a f1-65 or 68. You will want to go with the F1-68 to help with yo= ur overspeed issue.

Thank you for your email and interest in our products,=
