So...which turbo did they recommend?
Read the article last night. The target was 300-350hp
Ken Duttweiler - Precision Turbo 3254E - Capable of 470hp as he likes to size turbos capable of supporting 30% more power than the original goal.
Exile Turbo - T04E-57 with a TA31 Turbine wheel in a .63 A/R housing. 38mm Wastegate
Garrett - 53mm GT3071R (PN 700177-23) using the midrange .82 A/R. Says an intercooler isn't needed if the intake temp stays under 150 F.
Hellion - 54mm Compressor "This supports the power level but still has great response. A larger, 61mm turbo will support 400-500hp,". A 26x6x4 Air to Air Intercooler could add 50hp at the same boost. Start with an A/R of .81 in a 62mm turbine housing. 35-38mm wastegate.
Precision - PT6266B Ceramic bearing can hand about 20 times more thrust load than their hydrostatic bearing counterparts. Roughly equivalent turbos are available with hydrostatic bearings at a considerable cost savings. Mate the unit's 62mm compressor with a .58 A/R T4 tangential turbine housing.
Turbonetics - GT-K 500. An improved descendant of the classic T04. HP-61 compressor wheel and an .82 A/R turbine housing with it's proprietary F1 wheel. At 5psi they forecast 320hp without an intercooler and 335hp with one.
