Anyone running a H2E turbo

[Cummins Corvette]

I am thinking about a new turbo as my hx 35 is reaching it's limit. I live at 4500 ft elevation and don't like a lot of smoke. I am trying to get my6eatsv8s to respond but no luck yet. I haven't been able to find any info on the h2e other than that it comes from an L10 cummins. Given that, I think it would have real bad lag. Any info (cost, reliability, lag time, max boost, egt reduction) is appreciated. Mayhaps a comparison with an hx40?

I'm sure Adam will respond, but the H2E is bigger than the HX40.



Stock, it would have terrible lag and be a poor choice for you considering your desire for lack of smoke and your altitude.



Adam has a hybrid turbo that I believe came from a Pias (good turbo guy). He's running a tiny exh. housing to help spool it up faster. It's similar in concept to what KwikKurt is doing, only with the next size larger turbo.



Adam has mentioned several times that his turbo spools up at 1400 rpm versus 17-1800 for the HX40. That is the same range that my 40 spools up too.



Hope this helps.



FWIW, there are HX40's out there being hammered day in and day out at 40-45 psi boost that are working flawlessly. We just don't brag or post about it because that's what we expect it to do.

CAnderson,



Smoke & the HX40-16 is not a problem, unless you're WOT in low rpm. Spool up is slower than the HX35, but definately not objectioable to me. I drastically reduced the lag with the BHAF. The HX40 flows so much more air, the stock airbox doesn't hack the mission. There is so little lag now that I'm wondering if it's the same as the HX35. Definately not a problem solo or towing.



I'm @ 4500 to 5000' every day & am towing at elevations above that! Gary was following me the other day in stop & go traffic & didn't see any smoke! He was very surprised. I didn't even know he was behind me or I would have done some serious WOT lugging.

ok on the cost thing it depends on if you supply me with a rebuildable core, then its suggnifacantly a reduced price as far as the h2e. The price for a hx40 hybrid is the same as #'s I've heard for Kurts. Once again if you already have a hx40 I can get you a housing hybrid or you can even send me one that came on you truck to have machined for even less. The backing plate to bolt up to the hx40 down pipe is a little bit more, but if you still have a 35 downpipe you can use yours.

Email me for prices.

Reliability, the h2e doesn't go off its map until 48psi, meaning its way more efficiant than the hx40. Its also got a 9mm shaft verses a 8mm shaft so its inherantly stronger.

lag is similar to a hx35 with a 16cm2. More than a stock turbo for sure but again this turbo is aimed at guys with more than 400hp for sure. The hx40 will have less with a 12 or even a 14.

At my max power my egts were reduced over 100 degrees verses the hx40. But there again I'm around 1900 so its a matter of power, it deffinately makes more.

email me with any questions.

Thanks guys. Hey Forrest- I have an auto with a 91% tc, so lag is bad. Bill K told me it would be but I almost wish I had a 93% because at full throttle I still get about 500 rpm in drop when the tc locks, well almost full throttle (tc saver).

a-hunting I will go, a-hunting I will go, high-ho the turbo lag...

Just wondering but where do you go to buy a H2E?

Turbos

My experience is you don't want to run that H2E without hybriding it. It's too slow if you leave it stock.



Consider one of Kurt's Kwikspool turbos which will give you more air via a larger compressor and the spool up of a HX35. I've driven his truck and it's SWEEEET!



TxKid, most of us venders here can provide you with a turbo.

 

[TxDieselKid]

so your the right man for the job...

Nowel,

So you can get me a H2E Hybrid? I am not in need of a new turbo yet, but when I add DD 3's or super mentals(have not decided yet), and DTT goodies, then would the H2E be a decent choice? What type of price would one of these run compaired to the HX40?



When you mention hybrid, do you mean something like what Majastic does to it?

Super Mentals



Usually when folks use the term hybrid when talking about turbos, they mean the exhaust housing is not the normal one that comes on whatever specific model of turbo is being discussed. That's the most common turbo mod these days, after the Majestic problems earlier this year.



For example, the HX40 comes stock with a 16 cm^2 exhaust housing. I think KwikKurt's HX40 hybrid, among other modifications, uses a 14 and he may even offer a 12 cm^2 housing, to help the turbo spool up much faster than it would with it's stock housing on it.

NO WE DO NOT DO ANYTHING LIKE MAJESTIC

majestic was clipping the turbine fins to create more of an angle suposedly to decrease lag an for more boost, they also were putting a "bullet" on the compressure bolt.



Fyi your right the hx40 does come with a 16cm2 but with a different A/R<R is what is different when compairing the hx35 with a 16cm2 to the stock 16cm2 that comes on a hx40. The "R" stands for radius. The R is bigger on a 40 than it is on a 35. Anyone know that the smaller the circle(like a tire) the faster it spins. So because we are putting a 12 or 14 on these turbos they are even faster cause now we are talking the "A". Both the A/R's are smaller. Hense a faster spoolup.

Hybrid usually means using parts from more than one turbo.



I also have the same turbo as the kurts, a hx 40 with a machined housing.

The price is the same as his also.

I can testify to what HVAC said about running the H2E in the stock form. I'm not seeing boost build up until about 2300-2500. Lots and lots of smoke.

 

[TxDieselKid]

bang it into my head because i still don't understand that 2+2=4....

So then would it be possible to put the exhaust from an HX40, on the H2E to get it to spool faster or is that what the normal hybrid of this turbo is? Couldn't you do the same thing on the HX55? Why is the H2E more popular then the HX55?



Smoker,

What is your set up on your truck?



Just a big dumb dumb,

[Smoker]

Someone help me out here. I think that the H2E is a shade bigger than the HX55. The HX55 also costs a little more. The shaft may even be smaller. As for my set-up; lots of fuel, big turbo, horrible drivability. My truck is mainly a sled puller. I do drive it on the weekends when it's running.

 

[MY6EATSV8'S]

tx kid, I tried the stock hx40/cm2 housing on my h2e witch did make it better than the 17cm2(smallest that comes on a h2e) but it still wasn't good enough. You still have to do all the mods to the h2 to make that work anyway.

Smoker is right, the 55 is basically a wastegated version of the h2 so its more expensive. The compessure side is 50cfms different but also doesn't have the p/r that the h2 does. Smoker you should consider my version of the h2 for yourself. You get all the benifiets of a big charger with the drivablilty charactoristics of a small one.

 

[HoleshotHolset]

I'm considering the H2E, that's for sure...
