Starting research for the future, looking to do a set of fun driving/light towing compounds (12k# for maybe 2000km/yr). Wanted to use the 351cw as i have it. I found a hx50 that he says has a 17 divided EH and 67mm comp with internal WG, thoughts if this is a good match up?

 

What the exhaust side of a 50? I would think with an external gate you could keep the drive pressures down and it would spool wicked fast. But I know little to nothing about pairing compounds. As I've read it the primary should be able to flow double the seconday.

 

17cm2, has water cooling ports too. From what i can find the 50 flows 90-100lbs/hr while the 351 is 55lbs/hr i think.

 

The hx-50 sounds like it may be a little on the small side for a primary. Especially only have a 17cm turbine housing.

 

I was asking about exhaust wheel. I agree that it's a small primary but with the lack of rpm with these old pumps..... Plus the fact he will more or less need to "respool" each shift.

 

I sent him an email about the exh wheel size, in the ad it states its the smaller of the two hx50's if that helps.

 

Turbine wheel is 86/77mm
