16 CM or 18 CM housing on HX40?

[Bigsaint]

Kevin Goode, I have no idea but it sure does not sound right to break the H2E at 42 psi's, or the HX40 at 34psi's. What year truck do you have ? Maybe one of the experts can help you on the TDR can help you !!!

In response to Bigsaint's request I would say that the HX40 is limited to 50 psi, any more any you are naturally aspirated with a headache! #ad
Meaning, no more turbo charger.

I've seen the devastation left from a blown HX40 and it's not pretty. People, there is a reason we run wastegated housings. The HX40 will not tolerate over 50 psi. If that were not the case then we would run non-wastegated housings and let the boost run to the stratosphere! I Have to question people that post that they run nearly 60 psi(68 psi was quoted earlier) boost when they also mention that their boost gauge only goes to 50 psi(in another post).

The H2E has a larger shaft and can run a bit more boost.

I recommend the HX40 with the 16cm2 wastegated housing.

Thanks Nowel !!!! I have another question for yourself or anyone else that knows the answer. If your HX40 is wastegated at 45 psi's, is it possible to go over that number or will all of the boost be dumped after 45 ?

Need some good imput here! On my 2001 HO 6-sp running dd2's, EZ etc. I was able to get more HP & torque (peaking at 2200 RPM), Then running BD stage 3's , and EZ (peaking at 1800 Rpm)? I lost approx. 35HP in the process of going to bigger injectors!!@. . Would the HX-40 16cm compensate this lost of HP with the stage 3's and possibily exceed, or I'm I better off staying with the dd2's??? Does anyone have any dyno info with simular set-up as mine?? I don't want to spend extra dollars if the HX-40 doesn't give me any gain on the 2001 HO. HVAC? Sportbike? Tks.

 

[HeberRam]

Sportbike... I'm intrested in purchasing an HX-40 16. Pls e-mail the particulars etc. thanks.

It seems you are chasing hp. I recommend DD3s and get your Edge module reprogrammed by DD or Edge to the DD specs. At that point, the HX40/16 will give around 25 hp more You might try selling your old injectors on the forum classifieds, to help support your "habit. " #ad

With regards to turbos and their inner components, they get "seasoned" from many heat up/ cool down cycles. I have mine in for about a year and a half now and it's still fine. We broke one at Englishtown with the racer and it was pushing well over 60 psi and it had only been on for two full passes. The next one that went on the racer was wastegated for the first twenty passes at 50 psi. After that, the wastegate line was removed and the hole was plugged and she runs just fine. On my truck, I had been using a Caterpillar 70 psi liquid filled boost gauge at the track and an Isspro 50 psi boost gauge at all other times. I just replaced the Isspro with the Autometer Ultra Lite 0-60 psi boost gauge and it's nice to see where the boost is once again without pinning a 50 psi gauge. You'd think that with a 5 speed truck all the torsional stress that turbo goes through each time the truck is shifted would be worse for it. Go figure. Piers and Mike from A. W. D. seem to think that there were a rash of bad turbos with flaws in the shafts from Holset. Anybody living near me is welcome to come for a ride and watch the gauge themselves.

Diesel,Thats great you are able to run that much boost on a little HX-40. You guy,s are the only people that I know of that are able to run those kinds of boost numbers with out breakage. You would be much better off using a bigger turbo. All that little turbo is doing at that kind of rpm is generating heat. A H2E or a HX-55 would be a much better chioce or better yet twins.

I was there at the dyno runs on Heber's truck. I think he's getting plenty of fuel because there's lots of smoke. There's just not any boost. I've got the same problem on my dd3 ETH - no boost - maybe 31 lbs. Heber was making as much power with his dd2s as I do with my dd3s. After Heber's run, Brett put his stock injectored ETC on the dyno, and with just a EZ and PE beat the best figures Heber or I have done by 25 or 30 horse. When propane was added there was only maybe 30 horse increase and still no increase in boost. All the clamps are fine and we tried a 0880 K&N also - no boost - but he's sure getting lots of fuel.

John,


You make the HX-40 sound like its HY-35
#ad


IMO: A 40 is more than enough turbo for 99% of us here. TOO MUCH turbo for a lot of us. If my goal were 700HP, I'd look at Twins and larger turbos. The 40 will live at 500 & 600 HP with higher RPM levels than stock. This is proven. Many of us will never get near those HP figures.

After reading your post, a new guy to the TDR may get the impression the HX-40 is small & inadequate for a high HP application.

Correct me if I took your post the wrong way. #ad

I have to agree with Hemi, in my short but very happy so far experience with the HX40, I really don't think I need MORE (at least not yet). John's twin set up looks great, but I don't think you REALLY NEED IT for an everyday driver and sometimes used puller. But then again, my stock ETH was great and had more power than I imagined it would before I added the EZ. I couldn't justify the mods. I have now, except that it's sure fun having them, guess the same goes for turbo's. Do a search on the TDR under HX40 and in the early days (6-9 months ago), the HX40 was huge in comparison to the HX/HY35. Now, as we continue to progress into ever higher expectations of HP, the H2E is "somewhat small" and not for all applications. My hat's off to sportbike for his efforts in the turbo field, but I doubt my truck will see twins for at least a short while now.

Critters, I would caution Hemi and Bigsaint that John's post was directed at Diesel5. 9. You are taking his comments out of context. The HX40 is an AWESOME turbo! Big Bob was talking about a H2E last week and I emailed him that he should go with the HX40 with the 16W housing since it's the sweetest huffer I've seen for mid range horsepower levels. The HX40 is super sweeeeet!

John and I have been doing a lot of research on turbos and our target is above the 500 hp mark. I believe he was referring to the boost levels that 5. 9 was quoting and relating that for making big power we have been told that the HX40 won't cover the cfm necessary. The breakage problem of the HX40 has been well documented so I limit my boost level to 48 psi to avoid shrapnel induction.

[BIG BOB]

Thanks Nowel for bring this back into prospective for me. I was kinda getting lost trying to keep up with where this tread was going.

Look like the 16 cm2 housing is the way for me. I just want to make sure that I can get the EGT's form 1600 back down under 1350. I only want to do this once!

Do you think a EZ would help?

 

[sport bike]

HEMI,HX-40 is a great turbo for every day. It,s not big enough for 500-600hp. Just because you can hit that hp level with it doesn,t mean that the turbo is operating at the efficience level it was designed for. It,s like trying to make a HX-35 make 400+hp. It will do it ,but you will make more hp with a HX-40. At 500+ hp levels you need a H2E or a HX-55. You will lose some low end drivablity. On my truck the H2E worked great,But HVAC tried it and lost low and mid range hp. This proves that you need big injectors and lots of timing to get a big turbo like a H2E started. Hope this helps.

[HEMI®Dart]

John,
I understand now. That post was directed towards Chris T. Chris has one of the strongest 12 Valve trucks at the TDR. He has the HP to experiment with larger turbo's.

I believe guys running the HX-40 would disagree that the Turbo is is inadequate & too small for the 500 HP range though

[sport bike]

Hemi,
Anybody that would disagree hasn,t tried a larger turbo or looked at a compressor map. If you look at Chris,s truck(just because it,s the most extreme case I know of. )and try to plot the air flow of a 5. 9L making 58psi at 600hp. That equals to 1200+cfm. Thats with a turbo that it,s max flow is 800cfm. If you look at a compressor map you usauly see 5 bands or so. The closer to the center you are,the more efficiecnt the turbo is. The outer band is concidered the max limit. To hit 1200cfm,s you would have to add about 5 more bands and another page to the top of the map just to plot it. Thats why I said that Chris would make more power with a bigger turbo. It,s also easy to see why HX-40,s break when your tring to spin them so hard. Your just spinning them way past there design limits.

Sport Bike, what is the "sweet spot" in regards to boost with the HX40 ? Nowel stated that anything over 50 psi's = chance of running a non-turbo truck. Just curious. Also, is it true that, even if you have a wastegated turbo, some of the "extra pressure" can find it's way around the wastegate and raise your boost beyond what you have the wastegate set for. I was told that this is possible in a heavily fueled rig, especially if you spike the boost real fast.


Scott W.

 

[sport bike]

The sweet spot is up to 40psi. It,s hard to ask for anything more from your turbo. It,s still real efficienct up to 48psi. I would set the wastegate at 45. That way you have a comfort zone. Yes,if you have enough fueling boost will creep up. If you set your wastegate at 45psi,thats when it starts to open. But it might take 52psi to fully open the wastegate. It would take alot of fuel to make 52psi with the wastegate all the way open. Hope this helps.

[DieselB59]

I'm starting to get the impression that this thread is being questioned as to the possibility of leading the masses to destruction of their turbos and that's not where my intentions are. I wish to state and only state that the fact is that I have not yet grenaded one on my truck and I am probably pushing the envelope with it--especially being a 5 speed truck and the shaft undergoing a whole lot of torsional stress in comparison to an automatic where it spools up and loads up only one time per acceleration run. Mine sees 20, then 0, then 30, then 0, then 35, then 0, then 50, then zero, then 58 as a final output before I run out of quarter mile space. This has to be worse of than that of an auto.
