What to do what to do???? next step?
 

With my mods I have what would you do?

I have a option to run a hx40 pro 60/76/18 or the stock turbo.

I use this as a dd and run the 1/4 miles through the summer?

Looking for the most hp with fuel only.....


thanks

i'd go with an hx40

Make sure that HX40 has the upgraded stronger shafts.

Why and can I reach top hp with the mods I have?

Which size shaft are you talking about? Would you use the xh40 though?

An hx40 is decent.. a REAL hx40 is around 40hp over a stock turbo, but if you are looking to go FAST-FAST, I'd go bigger than an hx40.

The hx40 are great turbos and HAVE a tough shaft. Though if you hvae a few bucks to spend there may be better ones for going super fast.

It is the xh 40 pro. It has the billet compressor wheel. Shaft is 11mm

What boost level will achieve the 40 hp increase?

Honestly I'm not sure. Wait for someone more knowledgeable to pipe in. What size exh housing, what size wheel and how many blade?

stock or xh40?

xh40 pro has 60/86-76/64 18 exhaust 7 blade billet compressor wheel

ANY of the HX40's are out of their compressor map above 40psi.
The ability for making more boost pressure does not mean it will provide efficent power.
Also,you should run the 16cm exhaust housing for the best spool on a HX40.
I have seen HX40's go into the mid to high 400's for power on fuel alone and they are a great turbo for someone on a budget.That being said they are known to break their shafts and blow the covers off with too much boost pressure.Most guys who run them pin the covers for longevity and are careful when they lift off of them.

Are you talking about the hx40 or the hx40 pro?

The one I have is a wastegated turbo that started in production in 2007. This is not the standard hx40 model.

The shaft is a 11mm and is alot bigger than the hx35

The only thing not relevant is upgrading the shaft in his post. I'd run a 16cm housing, 18 is too big, and I'd stick around 35psi like on the hx35.

why would they wastegate an hx40 with a 18cm housing. i doubt your pushing enough fuel to overspool that 18cm.come across a 14cm housing for me and ill sell you my 16cm housing!:tu:

Dan...
They did not make a 14cm exhaust housing for a HX40,its 16cm and up only.

Joe....
I don't care which version or what year it was built its a HX40 correct?.
Any boost level above 40psi and its out of its compressor map and producing hot air and not cool air charges.Most all small to mid framed chargers are only good to between 40 and 50psi before they run out of their compressor map.If you want big boost and wider compressor map ranges then you need to go to alot larger charger than you will ever get lit drag racing or daily driving.There are some S400 framed singles that can be used but the trade off is how late they light and how much of a pain they are to daily drive.

Your looking for a single charger to make big boost,lower your Burban's ET's and still be street friendly and I am trying to tell you that charger does not exist.That type of charger has been sought by every diesel owner since the beginning of the performance era and has yet to be found.the ONLY way you get a good compromise is with a hard hitting set of twins like a HX40/HT3B combo or a S300/S400 combo.Otherwise the low end lag will kill you and drive you nuts with a street truck with a automatic.

I didn't say anything about upgrading the shaft,there is no way to do this on a HX40.The shaft size is what it is from Holset and there are no upgrades for it that I know of.

Cant you get the phat shaft for the hx40??

What size does the phat shaft have?

Dunno I've just seen people with them. Would have to ask someone more knowledgeable

the phat shaft is the name of a turbo from industrial injection... it isnt a replacement shaft for you existing turbo.

phat shaft is a 11.75 shaft the one I have is 11. Almost the same size:jump:

if you dont use that 40.... i can put it to good use:w2:

no, the phat shafts are turbos made by industrial injections i think correct me if im wrong. but they are there own fleet of turbos. you could also try a superphat shaft 64/71/14 or something in that matter. they are hard hitting turbos. also to your wallet. i dont think you could spool it quick tho. maby try the phat shaft 62 or something. im sure hammer will chime back in soon.

and thanks for the info, i thought you could get a 14 for a 40 my bad:argh:

Joe...
The Phat Shaft and Super Phat Shaft series are turbos made by Industrial Injection and they are all based off of the S300 chargers.I'll stick with what I said earlier and reccomend a set of twins for your Burban if your wanting quick spool for racing as you will never find the "perfect" single charger to fit what you want to do.If you go for a qucik spooling single you loose on the top end and if you want one to run hard up top then you loose the low end spool up.

If my truck was a automatic the charger thats on my truck,its a High Tech Turbo Pro-Street 66/71/13ss,would be a real PIA to daily drive as the low end lag would show itself.The low end lag of this charger is easily driven around with the tighter stainless steel exhaust housing and my 5spd as I can get it to drive through the lag wall without any surging.As I said,I gave up the quick low end spool of the 62mm for the top end charge of the 66mm and I just deal with it.

Dan...
Not a big deal,I have someone looking for a tighter exhaust housing for your HT3B.

thanks hammer, i looked forever on the web, but i called my local diesel injection shop to see by chance if they could do anything, and he said hed call the turbo exchange group and could prolly come up with a 23cm housing for under 200$. im awaiting a phone call. hopefully it goes through! thanks

Do you know how much your 66/71/13ss lbs per minute is?
