Here is a link for the compressor map of HX 40/35 Dodgezilla tubo, what do you all think?

You must also click on the technical info tab, it will not let me link the tab.

 

Guess we'll have to wait for Justin or someone that can interpret the things to chime in.

 

Why must they use CFM? AAARRGH!

They are correcting to CFM using PSI of 14.6, temp of 85º and pressure of 29.4" mercury.

At the higher PR, it's around 800cfm. I'll crunch the numbers and get back to ya...

Cool!

If you are able to compare to any other popular turbos that you know similar facts for... Please DO!

 

I'm not 100% confident of my correction, but the compressor SHOULD support 475hp because it flows about 61lb/min.

This is a little smaller than most 62mm-class B-w turbos.

I highly doubt that a DZ could really make 475hp because the turbine can't efficiently make enough power to spin the compressor that hard. Once that turbo is making bigger boost numbers, drive pressure soars as the tiny turbine gets overwhelmed.

This is validated by the fact that many full HX40s have gone 475hp (some over 500) with their larger turbines and the same compressor.

I'll let you know how this does at a later time, as I'm currently in the market for one. If you have the older style exhaust housing with the wastegate that is divorced from the compressor housing, the dodgezilla is one of the cheapest ways of getting into a performance turbo. My latter plans are to hang an S400 off the DZ using a plubing kit from Rip Rook. It's not a perfect setup but should do all I ask of it.

 

Now how is the DZ cheaper than the HTT setup. I believe that HTT sells the upgrade for 275 bucks. I don't know if they use different size wheels, but HTT's website claims to use the biggest wheel available for an HX 40. Today on the phone with HTT, I kind of gleaned that the hybrid is "great for guys that come in with new exhaust and intake and would like an upgraded turbo." They also quoted me 675 to have my HX 35 rebuilt, shaft balanced, and hybrid wheel/housing installed. Now i will admit that the DZ non-wastegated turbine housings are the cheapest I've ever seen.

 

I thought it hurt performance to not have the turbo nonwastegated? Is it better to put one on or leave it with out?

 

Thats what I'm saying. I have a wastegated 12cm housing, and for 675 I can have the DZ. I talked to HTT and being that I have a HY-35 there is basically nothing I can do to it. So I'd have to pick up a used HX and then have them work it over for 675. Thats about a grand for a turbo that really isnt worth the price. I'd rather spend the 675 on the DZ with no exhaust housing and the 75 bux I spent on a used 12cm wastegated housing and be done with it. If I'm going to spend a grand I'll spend the extra 300 and get a S300 based turbo. Just my two cents though.

 

Not if the housing is the right size =P Running a wastegate lets you run a smaller housing.

 

While we're on the subject, I was thinking of doing the 35/40 thing from HTT also, but someone told me that there would/could be as much of a chance of breaking a shaft with the larger comp. wheel on the 35 shaft as it would be just runnin an HX40 with the supposedly weak shaft. Is this true??

 

Yes and no. The shaft is the same size, but the exhaust turbine wheel is smaller on the HX 35 and since the hybrid uses an HX 35 turbine exhaust side and the biggest HX 40 compressor side available, it is more vulnerable.

 

To anyone making a hybrid or even buying a new turbo, I would highly suggest gasket matching it's inlet! I did mine and on the entry side for the front 3 cylinders the housing was protruding in the way about 5/16". I don't know exactly how much that would cause drive pressures to go up but for the piece of mind and 45 minutes of time to do it there is no downside...

 

I think you're telling me it's just more vulnerable than the HX35 in it's stock unaltered state?? Correct??
