Holset PRO 52 turbo

[ProMac1K]

Thanks for the update... ...



So what could you compare the turbo to as far as spoolability and size? H2E? HTB3?

 

[cummins4408]

what would you consider selling the Pro 52 for? just curious how much it takes to buy it and curious as to how hard it is to find smaller housings to fit these chargers. I may have one bought with a bigger housing and will definately need to go smaller.

How many have blown up a pro52 and at what boost pressure?

 

[mrsmith]

Ask me June 11 when we get back from the London,OH pull :-laf

how much fuel would I need to get out of my 12v to push this thing? Is it bigger than a SP66/14

From what I understand the pro52 has a 71mm compressor wheel, not sure of the turbine wheel. So it's much bigger than the sp66.



How much fuel? Well probly enough to where it wouldn't be very streetable. Touchy throttle and pullin tractor idle haze, and maybe 4500rpm takeoffs :-laf . .

 

[wildmanben]

sounds like fun to me...

 

[zstroken]

71 mm inducer and pretty laggy. Like it has been said though it will move some air on top.

so who thinks itll keep me cool... bc i dont see it happening

I am currious as how it comapres to a GT42R-94 with 1. 01 A/R housing.



With enough fuel the Ball bearing GT42 would make on fast spooling single sled puller... and still meet the 2. 8 rule.

NOT STREET FREINDLY turbo.

Looking forward to the report!!!

 

[jwilliams3]

What is the inducer diameter for the GT42? I thought it was like 76mm? (too big for street class without bushing?)



Someone spill the beans so I dont have to buy one to find out!! :-laf

yeah and the price and where to get one

 

[smokinrod]

it meets the 2. 8 rule it has a 70. 3mm wheel , II sells them but there a little pricy,but they sure take a beating. II told me they like them because they move a ton of air since they have such big housings. Diesel freak I will report tomarrow night the hook tonight was all dust and I don't run a breather so I just hooked my Excursion, but I am hookin at a big pull in marshall ,MI. tomarrow at 4:00, playing around it looks to be very promising.

 

[jwilliams3]

Whats the difference between a gt42 and gt42r?

 

[smokinrod]

42R is there race seriesit has a custom wheel and is BB,

Well I pulled at a real track and wow , I took 1st in the hot diesel classevan after all the carnage, I got to 255-260ft and lost the driverside front axle shaft sending me flying across the trackwhere at 289 my 70 looked up tight and snapped somthing enteral because it won't move. but the turbo rocks I felt like Terry Corpess LOL
