Need Pro 52 info!!

[Diesel Freak]

I know someone must have taken one apart!!!!!!!!!!!!!



I need turbine and compressor inducer/exducer sizes?



also would like to have the turbine housing size.



While prolly a pipe dream, but a compressor map would be nice too.



and NO, I am not looking for that POS Holset propaganda that was published in the TDR rag!!!



Thanks!!!

 

[BPonci]

Buy one and let us know what you find. Doesnt money grow on mamma's tree?

 

[Diesel Freak]

That would require a Sugar Mamma!!! Whick I don't have!!

 

[Diesel Freak]

geeze, over 100 views and not a soul has gotten out their calipers?

 

[jwilliams3]

IIRC around a 71mm compressor wheel, dont know on the turbine.

16cm non wastegated turbine housing.

 

[Diesel Freak]

now we are getting somewhere



who has the compressor exducer size?



Turbine specs?

 

[Diesel Freak]

wow awful quiet!!!

 

[J.Davy]

I might be able to help but I am not to sure exactly what the inducer and exducer are,and more specifically where you would measure them?I am curious what application were you lookin at for this turbo?I would like to build a set of twins with my stock turbo and my pro-52 and externaly wastgate them both. What do you think?

RE: Pro 52

Hey Diesel Freak I'm at home and can't remember exact sizes, but Shane knows this stuff in his head. I think he has some Pro 52's in stock. And probably has comp. maps to fax. Call Shane or Brady tomorrow 1-800-955-0476. PS, Any thing to help.

heh heh why do you think I want the info!!!! A twinset for making 55-60 psi, a decent Density ratio, and support 450-475 HP all day long, and spool faster (and earlier) than a HX40.



On the Compressor, the inducer is the small diameter on the wheel, the exducer is the large diameter.



On the turbine, the inducer is the large diameter, and the exducer is the small diameter

 

[Diesel Freak]

So, 71mm inducer?



that gives an air flow range from 80 to almost 100 LBM/Min

Cliff, I'm curious! Is it worth the cost of the turbo over using a BHT3B as a bottom turbo! Yes I know they are not the most efficient but they are cheap!



I hear you on the lower efficient boost at say 50 psi

[Diesel Freak]

It is more than efficiency with the HT3B. The biggest issue I have with it is that it is friggin heavy, and with the limited housings available, that tank of a turbine accelerates sloooooooooooooooooooooooooooooooooooow!!!!



The HT3B equipped twinsets normally have an overly larger turbine housing to keep boost low. I want a smaller turbine, with a tighter housing to get things rolling sooner (waiting till 20 PSI on the top turbo before the bottom lights is friggin lame) then I would use a wastgate on the bottom turbo to dump the excess and keep boost between at a controllable level.

Well my PDR twin set up is lot faster than that!! As soon as the PDR Super HX-40 hits 10 PSI the PDR HT3B is off to the races. In 4th gear the 40 starts spooling at 1400 RPMS and by 1650-1700 it's the HT3B is at 20 PSI. My rear tires don't like how fast it spools now :{ They really would like it faster.



Now granted my HX-40 was one of the first Super HX-40 Piers did, and when I tried HebeRams Regular PDR HX-40 mine spooled up alot faster.

 

[Diesel Freak]

10 psi is good, but I really want it faster than that.

 

[drawson]

You don't want much do ya :-laf

 

[Diesel Freak]

heh heh nope. Oo.

 

[KLockliear]

Call Lenny at Dynomite... he may have the pieces of the one he blew up still laying around.

 

[Diesel Freak]

heh heh , I bet that thing is on it's way to be turned into razor blades and Sprite cans
