Which Turbo ?????

[BigBadDodge]

Okay guyz, I need some advise here.



I may be in the market for a Turbo upgrade and am not sure what to go with. I have heard lots about the shaft breaking on a HX-40, and I have heard that the best thing right now might be the B1. but is that the best thing for a 24 valve trucks only ?? anybody runing a B1 on a 12 valver ?? if so how is it performing ? what about the Piers modified HX-40 I heard lots of positives on it as well. will a larger housing 16cm work for now ?



I plan on stopping, or at least controling, my HP addiction around the 500rwhp mark so I would like to buy just one turbo now that will work with my current set up (see signature) plus the 370's I already have, and work as well around the 500hp mark.



Idea's !!!

I'm going to get the B1, but before you decide, call ATS in Denver. They have some cool turbos too. 303 431 7973 I called and talked to Don, and he told me about a hybrid turbo that flows more than an hx40, and spools more like an hx35, and it is stronger than an hx40. It is a very creative hybrid.

Turbos

BBD, I have not seen or heard of any comparison data regarding turbos and use on a 24v versus a 12v engine. Have you information that would suggest some turbos will work on one engine differently then the other?



My instinct is a turbo that will spool well on a 24v engine will spool as well or better on a dozen valver. Beyond that, any data we get on a twin dozen valved motor will only be surpassed when tested on a dozen valver due to the greater rpm range.

When it comes to turbo technology

Piers will always be a front runner with the modified HX35 (still feeling awesome) HX40 (can you say power) and that other (censored turbo) can you say Nasty??? (joe)



Keep up the great work Piers

 

[HVAC]

I would add that I pleaded desperately for ATS to let me test the turbo that CAnderson speaks of, but I have yet to see it. My position is that if ATS has the best turbo around then I'm knockin' that door down.



Reality is the B1 turbo is the best turbo on the market currently. That's all things considered IMO. It does exist and has been thoroughly tested with spectacular results.

 

[BigBadDodge]

HVAC, I agree that the B1 may be the best turbo currently. In fact I have been saving for one, and then somebody told me that they thought the B1 was best on the 24 valver so I thought I would try to clear some things up. I have no data just speculation and then on top of that most posts here are infact 24 valvers with the B1. do we have some one here who has some proven facts with the B1 on 12 valver ? What you are saying makes perfect sense though, works on a 24 valve, better on a 12 valve. Why would number of valves have any thing to do with it

 

[Bob Wagner]

The turbo menu is wide open

The B1 is the best turbo for what hp range?





Lot's of member would like to know

 

[Pthomas]

Good question Bob!

any 24v Vpump will not produce as much fuel as the 12vP7100!

but if there is a 24v with a P7100? and there are!

Things to also note. what are you gonna do with the B1? drag it, light weight tows?? thats all i would use it for. and the big issue COST$$$$.

PDRHX40w super turbo(my opinion) best dang bang for the buck for ALL around use!!! 20k tow or a drag run!

if you REALLY need air just get TWINS!

 

[BPINE]

Hey there Blowout, I will have some test data on the B-1 on a 12 valver soon I HOPE. I must say the H2 is working very well so far and I don't think you can hurt it.

I presently have Piers' Modified HX-40/16 on my truck

and I am VERY happy with it! It has been on the truck

for almost three months now. Piers "set" the boost for

me at 40lbs. and that setting has given me very good

low end along with alot more midrange "punch!"



I had the HX-40 on the truck while it was stock and

it did have some "lag" on the bottom end, but that is

all gone now since Piers did his "majic" to it! He modifies

the oil galleries, works on the shafts, and does some

"censored" work to the exhaust housing. I can tell you

that it performs ALOT better than a stcok HX-40!!! I realize

that alot of the HX-40's have "blown-up!" I was concerned

about it too. But Piers seems to have found the secret to

helping make them last. He has told me to keep my boost

set at around 40lbs. , try to "take it easy" when letting off

the throttle (don't bark it) and it should give good service!!

I run my truck hard and so far, no problems! The HX-40

has given me 27 more H. P. on the dyno than I had with

my modified HX-35/12. I haven't had a chance to take it

to the drag strip yet.



Hope this has you helped you some!

The B1 is the best turbo for what hp range?

B1 spools really well at or above 350hp. Kurt says it'll spool like stock above 300.

Things to also note. what are you gonna do with the B1? drag it, light weight tows?? thats all i would use it for.

It'll do them all well.



The HX40 no matter who builds it is over spooled at 350-400 hp. It's basically a hx35 w/bigger wheels. The shaft on it won't take the abuse of the HX35 because of the weight. when they fail they shear the shaft. Mind you this is from long discussions w/Kurt yardley on turbos and application. I have not owned one.



Autoworks destroyed theirs on the strip and there have been lots of people 'Huffing' '40s. It does not seem to handle 'normal' abuse well. It is well suited for 300-350hp trucks that are towing or daily drivers that need a 150* drop in EGTs. I believe it was intended for 8. 3's governed to ~2500 rpm. our 5. 9s are running 32-3500rpm. when we throttle back there is a much steeper transient in airflow which I believe leads to barking.



The B1 barks, or rather cavitates, pretty easily but it takes it in stride. It flows so much air . . its just awesome.



The B1 has a much larger shaft that is very resistant to damage. It seems to work very well towing. Yogibear tows w/dd2s and CumminNTStrokin has supermentals or the like that he towed with. Mind you they are not able to use max HP all day but they can tow while making 400-450hp .



The B1 is producing drops of 3-400* over HX35s and 200*+ drops over HX40s. Boost vs HP also changes drastically compared to HX35s. It makes more power at 36lbs than an HX35 at 42+lbs. I've been comparing numbers against the HX40 crowd and I'd put money on similar results compared to an HX40 though not as large.





It does not spool as fast as a HX35 on dd3s or a Kwikspool. It spools a lot faster than a stock truck w/a HX35 and it is very durable. I don't set the PEC to smoke 5 because it borders on offensive but when I do it spools like there's no tomorrow. I drive in a lot of small towns and my truck is rather distinctive. . no reason to draw more attention than necessary.



I have not towed with mine yet, but at 5/5 on the PEC in 6th, I nail it and there is a cloud then the smoke all but disappears. 70-100+ is just a blink!!



I can drive all but smoke free w/my dd3s by controling my foot. With the HX35 I could generate a cloud while rolling down the highway until I chose to stop.



In short. . IT ROCKS



I guess its tooo late to be short, huh?

 

[Pthomas]

Never mentioned the COST!Hmmmmm... .

and To "no mater who builds an hx40"...

Piers version is not JUST an HX40w !

Oh yeah and as far as AUTO-urks.

IT wasnt just #2 when that blew ! well over 60psi isnt normal abuse, and IT WAS NOT Piers version!

Ill break any turbo if i drive with no common sense even your B1

 

[Mark_Kendrick]

The cost has changed . . it was pricey, but the truck is WIFE proof as longe as she misses all the stationary objects!!!:-laf:-laf

 

[John_P]

Pthomas:



I couldn't agree with you more... ... ..... I like my Piers

HX-40 alot!!

Mark:



You are right that Kurt's B-1 is an excellent turbo. Since

"BigBadDodge" asked about Pier's HX-40 I was only

trying to give him my opinion of how it has performed

on my truck. However, as I said, I do believe that Piers'

mods will help these HX-40's last longer than they have

in the past.

[Mark_Kendrick]

I hope you're right. I'd hate to pull my turbo off in chunks.



I'd bet the Piers turbo is a great piece of gear. I'll keep my B1 anyway

It was initially thought up to TOW with. It just so happens its a good all around turbo, I just happen to hot rod with it.



And yes its exspensive, but its a hybrid made from 3 different turbos, don't like the price? Don't buy it... .....



This turbo definatly isn't for everyone... . I bought it due to the durabilty its going to provide me. I would try to run it with 325hp and above. Once I relearn my launch I should be just as fast as I was with my HX40 hybrid (not a Piers turbo).



Yes I have a PDR HX35 that is my spare, and it handles that job well. Its clearly out of its usefulnesss range on my truck... . but still makes 450hp... . just pegs the EGT gauge. I can't peg it anymore..... yet. Whichever turbo you go with it will be a good one... ... it would be interesting if someone could get a hold of both for "testing" purposes

What has it done for you as far as EGT's?



Darren

Oo.

 

[BigBadDodge]

Excellent info guys, just what I am looking for your real world results. I don't do any trailer type pulling or hauling but will be involved in the ocaisonal sled pull from time to time. BPine I will certainly be intrested in your B1 results when you get them especialy since your runing the H2e now, I forgot to mention the H2e in my original post, I had contiplated it before as well. I am pretty hard on my truck on a daily basis mostly those short quik runs to show off, maybe I will out grow that later but for now its fun and I don't want to break anything I don't think my stock turbo (HX35-12cm) is going to hold up much longer, it barks pretty frequently now when I get up to about 44psi and let off it. So far it seems like a toss up between the B1, H2e, and Piers modified HX-40 apparently all three have a bigger shaft which is the weak link in the stock HX-40 and the HX-35's.



Bare with me here guys as I am still in the middle of the learning curve on the Turbo's. I would like to purchase just one and not have to worry about it every again. Or should I say the old lady will only let me buy one, if it breaks I will be walking to the events



Thanks for all the feed back and if any body else has more real world exsperiences with the three turbos above on a 12 valver your info would be apprieciated.



Thanks again.

 

[Pthomas]

with the P7100

and full rack travel my egts are down over 200deg.

and it pulls like a rocket!

You say the mod HX40 has a larger shaft then stock? Where did you get this info? I'm going to check with Piers on that. Doesn't sound right to me.
