Hybrid turbo time

[Black93]

I was 0 for 2 on CF buying a he351cw. Both were sworn to be good and after I got them and checked them, neither were. No matter what you pay for one, if the seller isn't willing to pull the exh. housing & send you a pic, I would pass on it.

Well BILTIT, I thank you for schooling me on HE351s. I'll look at how people have set up wastegates. In my mind VGT would just complicate things further and make it more expensive. I seldom run the truck that hard, so I don't know where this HX35's limit is yet, but I know from others' expirence that the amount of fuel I'm moving is enough to need an upgrade. Also, I have a Suncoast converter, but I haven't installed it yet.

That's my concern exactly

[BILTIT]

Honestly, i wouldn't buy anything off CF.

I found mine in local classifieds. You have to search the truck it came off, most people selling turbos don't know what they are selling, just what it came off.

i have had mine turned all the way up and did not have a problem with egts,(from a stop to 90, netted 1400 degrees.) Pulling the sled netted between 1100 and 1400. And i could pull trailers with it like that to a point. A little tuning and you can pull them all day long without getting to toasty.(Maybe a valet switch) Keep in mind i had quite a bit of timing with these temps to. Noticed that i run noticably warmer with my timing back down to stock.
As for spool up, i can shift every gear and never drop my boost gauge to 0.

[BILTIT]

Ditto on shifting and not hitting zero boost.

Ditto on shifting and not hitting zero boost.

while that's a good thing, i can do that with the stock H1C.....

[Hansen01]

Without effort at 10lbs of boost? You must shift faster than me

Those numbers seem darn near too good be be true. I do have a valet switch, but it's always open. I'm going to give it a timing bump one of these days. I know a certain someone that can shift and be back on it before dropping to 0 with a Super40 Shifting is a skill and I'm sure I don't have it. I don't have to worry about shifting, so that won't effect my decision

It boils down to I'm too darn busy

Dont get me wrong, with the pump turned all the way up with a heavy load big hills will be your enemy in the temp range, but maybe if you did some afc tuning you could pull it off
As for pulling the sled, last year when i was running my hx 35 and no intercooler i pegged my 1600 degree gauge at half track... motor temp was at 220 when i got to the end...

The north half of Indiana? Hills? Nope I closed my valet and I'll see how much of a turd it is tomorrow. I haven't had it closed since I put in the IC and HX35. I'm not sure why people get so worked up about temperatures. If I remember correctly, Cummins rated these engines at 1200* EGT continuous.

That HX is starting to leak worse, so I need to make a decision somewhat quickly.

[Hansen01]

Your correct 1200 degrees. I pulled my head for a headgasket after multiple 15 to 1600 degree runs and all is well. I think temps like that screw your head up worse than the pistons cus my head was in dire need of a rebuild

I'm 0 for 1 on cf on a 351....I have a spare hx35 that I think i'm going to rob the turbine wheel from and machine the he351 out to match and then buy a comp wheel. who balances turbos???

i have a 12cm hot side, and yeah i make it to 3-4lbs from 10, and from 25 it doesn't get below 15. i might shift a little quicker, but you can only shift a gutbag so fast before it starts screamin at ya.

[PToombs]

I could shift mine fast enough to squawk the tires in 3rd. Then the synchro started giving me problems.
I don't know what the boost was, I was too busy driving to bother looking at the gauge.

[oldestof11]

My buddy told me i only get down to around 18-20 when i do the 2nd-3rd shift. The 4th and 5th are faster yet.
