If you will notice in the Turbonetics matrix chart, they only recommend a .81 A/R for the turbine housing. A "Q" trim turbine wheel, But look what HP they are saying what the .81 A/R is used for 1000 HP! A .96 A/R is good for 1200 HP.

I do not think Snowman is looking for a turbine housing of .81 or .96 right now that is good for 1000-1200 HP,just me thinking out loud.

The turbo he posted http://cgi.ebay.com/ebaymotors/GODSPEED-...#ht_3573wt_1042

Compressor Wheel diameter: inducer 56.59, not too big.
The compressor A/R is .70, that is not the inducer size of the compressor wheel.

Tlowe,
Your your turbo : http://cgi.ebay.com/ebaymotors/SUPER-T4-...sQ5fAccessories
Has the turbine spec you recommend for a stock 250 is .96 = perfect, correct? 54 MM inducer compressor wheel.
