Turbo recommedations for 475+ HP

[WadePatton]

Bear with me, I've read all the turbo threads.



I'm going to add DD3's and a larger turbo. I've ruled out the tuned HX-40 because everyone agrees that 450 is really the upper end of it's optimum performance. I'd rather be overcharged than under, and I don't want to go through two turbos to get the one I should have bought first.



My truck is an ETC, with DDUFM drag, Six speed. I don't tow heavy and operate at 600-1800 elevation in the South. Truck now makes 343hp and should be close to 475 with 3's UFM and 40-class turbo.



I also plan to add an ATS manifold, fix the supply fuel and work on my cold air. And I don't want to run pressures that threaten my head gasket. Plenty of time for that later.



I'm looking at the Piers 50, KSB1, or something from Pius. There is a lot of info out on the 50 and KSB1, but it is very difficult to get any info on Pius turbos. Joe says there's a Pius "Schwitzer" that is similar to the H2E.



Thanks to the vendors that have been fielding my questions so far. Now to hear something from the street. TIA

Why do you think you are over what a 40 will handle? That power level is right where just about all of our customers are running a 40. Even our current demo 01 at 460hp runs our version of the 40.



If you think EGT's will be too high, then add a cam. Less expensive for a 40 and a cam than twins, and at that power level, I'd say better performance too.



Are you planning future upgrades beyond the Stage 3's and UFM? If so, what? That will make a difference too.

Wade,the HX40 should be fine at 475hp. If you are a turbo barker,or have any drugs planned for the future,you may want to go with a sturdier turbo like the KSB1,or large housing B1. Im running the B1,and while i do have a touch more lag than a PDR 40,my turbo is still going strong over a year later. And I bought it off a fellow tdr member,who ran it hard also. I have shot nitrous at the B1,and my truck is run hard often. there is no doubt I would have blown more than 1 HX40 by now.

 

[ToolManTimTaylor]

Wade , What do you do more of? Street daily , or Weekly Drag strippin' ? Overcharged means also more lag (For a big single turbo anyway) on the street when towing (Even in your light aplication)things can get frustrating up at altitude ... and smokey. I find my setup allmost the perfect ratio (Cam would round things off even better) in terms of drivability , fun , working duty.

I hope more people chime in with their experiences here. Turbos seem to be becoming more important and I am up in the air as to what I want...

A good friend of mine has dyno'd at 490 rwhp at Muncie this year and then has backed that up at the track with mid 13's . He is running a PDR 40 with Bullydog 4's, Drag Comp, AFE Intake and 4 inch exhaust. Had this for about a year and no problems, his truck is brutally fast with virtually no lag.

 

[WadePatton]

I'm not saying that a 40 wouldn't meet my "needs" 75% of the time. Lag isn't really an issue. I'm looking for FLOOR IT and FORGET IT performance.



Some knowledgeable folks have put it in my head that I'd be topped out -right at the limits- of HX40 performance.



Keith- Not doing twins--not for some time. I'll do the cam and port the head before I go the twins route. I figure I might go with some Mentals or EDM's when I get bored with the 3's. (And maybe by then I'll have second truck and we can get just SILLY with this one. Oo. )



Snow Man- Barked the 35 by accident once, never again. That's part of the appeal of the Bomber series--practically indestructible, not that I'm hard on equipment or anything.



Tim- No serious racing, just a daily driver with some dyno runs thrown in. My favorite race is this 1. 5 mile steep hill coming out of town. I have to lift now because of the curves. It's MY hill. With clutch-easier to get around lag and no elevation to speak of.



Heck, it might come down to what pops up on the used market. I'm not a choosey mother. Or am I?



I suppose it would help if two or three TDR folks with big chargers would drive down here so I could hear, feel, see, smell a big turbo. All I've ever seen is photos and the ones on big rigs. Whoops I take that back, Stacked n Jacked was at Tom's GO last year with twins--but then I'm not after a two charger setup.



I'm sure I'll be thrilled with whatever I stick on it. I just want the thrill to last a while. Keep it coming!

FYI, we made 532 in the white truck with Super Mentals and a 40 the first time I took it to the drags. Best it ran with that setup was 13. 27. No problems with the 40. Once we put the drugs to it, we stepped up to the next level... H2E Hybrid.

How's about some conjecture?

How would the H2E affected the performance if that had been the only thing changed? Boost? Power? Lag? and EGT's?



Hey, I've got a 5" exhaust to fill up.

 

[Evan A. Beck]

The H2E has a wider efficiency map, and does deliver more volume of air than an HX40. Plus, the exhaust housings flow a little better too. The downside is a bit of lag on the bottom end. That can be dealt with though.

 

[KLockliear]

Our H2E Hybrid is a bridge between the H2E compressor and a HX-40 exhaust turbine housing. It is a little laggier than a 40 (bigger, more aggressive wheel and larger shaft to spin up), but more durable and provides more efficient boost as well (we wastegate those at 55psi).



The H2E Hybrid and a cam make a great combination at the power level you're looking at, but don't spool as good as the 40 and the cam.

 

[MD500E]

Wade, I have a friend who wants to sell his DD H2E hybrid, as he is going with twins. PM me if your interested. I agree that a 40 is going to be fine at 450hp, but If you want a once and done turbo then I would look at the H2E hybrid. A little more lag, but its ready to take on more HP as well as drugs in the future.

I have Haisleys hybrid HX-50 and it sure moves this big truck down the track pretty good. I have a Piers HX-40 to get me and my trailer to the drag strip. I dont think I will be happy though till I get some twins under the hood.

 

[drawson]

I have had my PDR HX-40(I think I got the third or 4th one Piers made) for 45K and have been at or above 475 HP for 40K of that. The highest I've Dyno'd is 503HP w/the HX-40 in the high hot dessert. I am now running the PDR HX-50 but the 40 goes back on to tow with.



If you are sure that your not going to want more the PDR HX-40 will serve you fine. If you are as addicted as I am you'll never have enough turbo.





I think I'm going to bypass the twins and go for triples

 

[WadePatton]

lag - not me.

I think every response/comment on lag is from auto transmission drivers. With a flick of the wrist and a tap of the toe, I have no more lag. I have the R's up all the time anyway.



Besides, if a biggun is too laggy, shouldn't I just ADD FUEL?



PM sent to MD500E



Speaking of lag--I'm gone, I'll be back Tuesday!

I think I'm going to bpass the twins and go for triples

LMAO

The pdr 40 is a great turbo. I have one on my 2002 ETH, w/ DD3's and an Edge Drag Comp. It's PERFECT for these injectors. I NEVER have an egt problem, and I've never had any problems with the turbo. I'm aroud 450 also. Whoever told you that it wouldn't work obviously was not talking from experience.

I never said it wouldn't work. Nor did they. The "Whoever" is a collective of some of our most popular vendors and other individuals who have very much experience making horsepower out of these trucks---WAY more than 500 .



Never doubted that the PDR 40 or anything else Piers Harry puts on the market isn't great stuff.



If you'll go back (search)and read approximately 921 posts in 50-dozen threads, you'll find that the SHAFT size and the loading stresses imposed on that shaft in the HX-40 is the main issue.



Yes, individuals ARE running 40's on ~500 HP trucks. Some folks are running nitrous and propane through their compression engines. Although both tricks indeed work, I choose to do neither with mine.

 

[TxDieselKid]

There is another set of hybrids out there from the east coast you amy want to think about also. One of these neat turbos is a 55 hybrid with a 16cm wastegated HX40 exhaust housing that has been modified to accept the bigger turbine wheel. The 55 is a bit more sturdy then the 50, so that's a big plus in my mind.



The other option I would go is the S3 turbo. That is the one that Joe mentioned from Pius, but also you can get them from the east coast.



Both these turbos are sold by JR Adkins. He is a member here, and will be happy to help you decide.

I think the 40 got a bad name back when majestic turbo was reworking them for a few guys. There where maybe 4 turbos that blew up and suddenly the 40 was a bad turbo. I know that guys blow them up, but for what HP you are going to have (probably more like 430-450) I see no problems with a 40. Also a bunch of the guys that are making big HP also have a stake in which turbo you buy and if you buy it from them. Just as an example, do you think that Kwickurt is going to reccomend an HX40 to you, heck no, he is going to want you to run a KSB1 or B1. (no offense to kurt ment, just using him as an example).



Here is my story, I have DD3's, Drag Comp and a PDR HX40 and have no worries. I am not going to lie and tell you that EGT is not a problem, but its not a big problem. The only time I have to back off is on 5x5 over 2700 rpm when the comp pours the fuel to it, heck by then I am over 100 mph and its time to slow down anyway.



Here is my advice, get a PDR 40, drive it for year or so... . then use it for the top turbo in PDR twins.
