Competition Holset Super40 and Pro52

[Kenny.taylor]

The 4038822 Pro52 adapter is angled to keep the turbo tucked in the engine bay. It also has a boss cast on both sides so you can drill and tap them for wastegates, gauges etc. This adapter also has excellent transitional flow from flange to flange.

130k rpm, what kind of boost psi is that? Is there any difference between the Super40 and a PDR40?

 

[lonewolf]

has anybody got to try either one of these out yet?

 

[jerrethomas]

looks like torque this should have his soon!! We are waiting to hear about the results.

 

[TORQUE THIS]

Yup, still waiting...

 

[HoleshotHolset]

I'm hoping to get the 52 shipped to me by the beginning of next week, I'll work hard to get it in ASAP and give results.

Mark:

Joe, how did you end up with one so quick???? Give me a call!

 

[HoleshotHolset]

Uncle Joe! How've you been?

I've been very busy at work and so forth...

Aside from work, I can't wait until the summer racing season begins... there's lots of pulls and drag races to attend this year.

Quick I have had this one (mine) for at least 4 weeks



How many do you want? Is Wednesday too late???

 

[BigDaddy]

Matt,



I have been fine

Aside from work, I can't wait until the summer racing season begins... there's lots of pulls and drag races to attend this year.



MTY

Any chance that you will be attending any events on or close to the Right Coast this year? Sure would be nice to see ya



You take care,



Joe

 

[HoleshotHolset]

Uncle Joe: This summer is going to be pretty nuts at work... they've been warning us about how busy it is going to be since last summer.



Are you going to make it out to IRP this year? As for the Right Coast... I don't have the foggiest idea when I'll be headed back that way. I'll be sure to sound the alarm when I do, though.

I bought one. Fitting it was pretty easy,I'll post later after testing.

First impressions are verry difficult to remain under 60 psi boost,spools up verry quick. The truck it is on is a 12v with a 215hp pump and DDP#4 injectors its best #2 only dyno is 615 hp. Cant wait to be able to try the PRO 52.

 

[CATCRACKER]

what turbo did you use to get to 615hp?



let us know how the two compare

 

[HoleshotHolset]

I bought one. ... Cant wait to be able to try the PRO 52.

So you tried the Super40 first...

I'd like to see a comparison between the 40 and 52... that would be sweet.



Matt

 

[jwilliams3]

Why a comparison Matt?

Are you thinking of increasing your 180rwhp? :-laf

 

[HoleshotHolset]

Yup! ... and I want you to be there to capture it on video!



Matt

 

[jwilliams3]

Will do.
