Which Turbo ?????

[BigBadDodge]

Yeah, it was my understanding here that he (Piers) did some modifying of the shaft is there something else you would do to the shaft other than beef it up some how ? I don't know !!

Darren:



Sorry about not getting back to you sooner on your

question. My EGT's have DROPPED almost 200 degrees

when running hard at the same RPM/speed that I used

to run with my HX-35/12. It will vary slightly according

to the outside temperature, load etc. but I that figure

is very close to what I am seeing.



BigBadDodge:



I believe Piers is or has changed the shafts on his

"modified" HX-40 from the "stock" shafts to the marine

shafts for better durability. I am almost positive he is

balancing the shafts regardless.



Hope this helps some.

HVAC,



I'm not sure if piers uses a larger shaft. Is the pinwheel the wheel that is attached to the shaft ( one piece). If yes, it probably is then.



Piers wrote a few months ago:



"The HX40 I'm working with comes with a slightly different pinwheel than the HX40 we normally use.

From there I take it apart and modify the oil bushings to make it more stable & better lubrication.

It is also balanced to tighter spec's.

I then take the exhaust housing and do some censored work to it, so a 16 housing acts like a 14 in the bottom end, but still has the flow of the 16 with the full 4" outlet for the top end. I also do the same thing to an 18 housing so it reacts like a 16. "

HX-40?

Could someone expand on the HX-40,as to the A/R . I have located a 40 with a A/R of 19. I`m assuming that this is refering to the exh. housing? Someone put me on the straight and narrow on these. thanx

One other difference to point out is the B1 has a 4. 5" outlet.

Kat,

Ain't it purdy!!!

My opinions on some of the questions and statements above. .



There is a difference in the way turbo's work a a 12V verses a 24V

To keep it simple on my KwikSpool Hx40's we actually used a slightly different Compressor wheel on the 12V's to help control a Surge you could get when letting up on the throttle.



Does the B-1 Work well on a 12V?... . The first Prototype B-1 was installed on a WAY OVER FUELED 12V almost two? or Three years ago..... Still Running and the Owner is still Grinning. And he doesn't have the Awsome Exhaust housing we are using.



Comparing the Hx40 to a B-1 Bomber is like comparing a Firestone tire to a Michealin Tire. One will likely Blow out if not treated within reasonable use the other will Take beating and abuse.



We are all working to build better products and some have limits that you cannot improve beyond a certain point.



The intereseting tests will be a B-1 Bomber to the H2e/12cm2... ... Soon to come about!!



As for the Hx40 line of turbos... ... Watch out for my . AT-4 ... ... . (Built with knowledge derived from the B-1) It is Almost finished with R&D and will be on a few trucks for further Durability testing Very soon. I will gladly put it against any turbo built on a hx40 platform. It Spools FAST and has a Compressor simular to the B-1 in size... . Mucho Grande!!!

KwiKKurt, Oh sure make it harder to decide by adding a onther turbo in the mix, the AT-4 ha as if it was easy to decide wich I want now. This is getting like buying a computer, you buy the top of the line and before you get it home there is something better. there is always room for improvment though, and I have a lot of respect for you guys that do the R&D stuff on your trucks for the better of the rest of us.





Mark, nice pic's



Pardon my ignorance but does the B1 come with a way to bolt up to my 4" exhaust sine it is has 4. 5" opening ??

 

[HVAC]

Scott, you will need to change your downpipe same as installing a HX40. We are having downpipes built to make thing simple for those doing their own install.

BBD, Sorry... . I know life is hard enough already! LOL



The At-4 will be a better choice for the trucks that are not going all out. Especially if they live in an area like LA... . Where a little puff of smoke will get the "Little Green Nazis" on your tail... LOL. Or the Extreme High altitude trucks.....



I am trying to keep your decisions as easy as possible. For example if you started out with a AT-4 because you thought 400 HP was going to be more than enough... . Then you ride in a 550Hp truck with Propane / Nitros or get bit by the 1/4 Mile ET Bug then the Upgrade to the B-1 takes about 20 Minutes.....



It is true that there will be improvements coming out all the time from all of the Performance product manufactures.....



I have several ideas in various stages right now... .



One is a device will make almost any of the turbos we run spool faster.



But here is what I keep in mind during my Dreaming / Designing / Bombing activities..... To try and keep the improvements easy to pass on to customers... . One simple example... ... If I come up with something that made the B-1 even faster spooling or lower egt's then It will be available at as low a cost as possible to the existing customers..... Probably like a Exchange program... . I send you the new improved componet and then you send back your old one... I mod that one and send it to the next customer.....



I seriously doubt that anyone will ever want to or need to replace their B-1... ... Even if 60 psi wasn't enough... . I am putting together a twin setup that will use the B-1 as one of the turbos... ... .

 

[Pthomas]

now your talkin!

twins is the way to go for more air to match the fuel our 12v's can produce

just dont forget the cost issue from the start!

Kurt:



I for one want to thank you and your "research crew"

for all the R&D you guys have done on these turbos

including your "B-1! Also, thanks for patiently answering

all my questions on the phone the other day about the

12v/24v turbo spool-up issue.

What did Kurt tell you about any difference in spool up?
