Its already got a J -hook, so thats cool....

 

Well i wouldnt really consider it junk, you just gotta know how to drive with that turbo, it'll cool your egts down real quick on the bottom end, but will make things hot up top. But if you can cool things down at the lower rpms itll also take longer to get the turbo hot up top. Your just going to have to watch your right foot. and boost gauge, cause i was able to get my 90' stock turbo with a 60mm compressor upgrade and 12cm turbine housing to push out 55psi!! way out of its efficiency range, but as long as you got fuel, itll keep boosting a small turbo like that.

try the hy, the price is right. it,ll cool better than the stock turbo. its not really that the smaller housings are"restrictive". depends on turbos comp. and turbine wheel size, comp housing size,mwe slot,waste gate map eficiency and more i dont know about. a 12 on an h1c is ok but pushes the turbo out of efficieny map pretty quik overheating the air. a 12 on an hx works great . i tested a 12, 14, 18.5 on mine, towing 6000 lb lloaded enclosed snowmobile trailer up 6 miles of 5-6% grade at 70 mph. the 12 cooled the best to my surprise. i tested with the he 351 , 9cm housing , it cooled 40 psi boost alot better than the hx. i measured the exuast wheel, its smaller than the hx or h1c. i dont know alot about turbos, only what testing has shown me.

 

I think that being at a higher elevation, the smaller exhaust housing don't hurt you're egt's as bad as when you're at sea level.

 

I bet it'll make things hot everywhere if you're not real easy with the go pedal, so what's the point? Electronic injection timing allows the small tubine housings on 24v's. That's one reason they don't have the same airflow issues dealing with too much fuel at any given point in the rpm range. A computer-timed injection event is not exactly the same thing as being careful how you drive it.

 

I still wanna try it out and see. I thought I had the 21cm housing on my truck??? can you change the exhaust housings on these hy35s? If i don't like it, I may try and sell it or trade it and try and get an hx35, or an hx40 or somethin else. I could probably buy that Super B special he has. How would that work on this truck???

 

Yea your truck being a 92 will have the lagmaster 21cm. my bad

 

The HE351CW has a 9cm housing and they are working out ok with out high EGT. Some guys are undoing the waste gate on them to make them run even cooler. Or am I wrong? I need to install my 351 to see what it does. Good luck.

 

as i mentioned in above post, he351 cools really well. i pushed mine towing at 40 psi, it cooled really well. i was skeptical until i tried it. i do run a larger i/c, out of 06 dodge.

 

Wouldn't the HY with the 9cm housing then be comparable to the 351 as far as EGT goes? If I was 92smokin blacky I'd at least try it and see. Free turbos can't get much cheaper. Then if it works out good we all know it can be an upgrade, if it doesn't we will all know it's will be good for an anchor weight. Good luck 92smokin blacky.

 

Regardless of the Housing size you gotta think, compressor size and how much air its gonna push. I can't find an actual specification chart on an hy.

I've read on a few other forums that their efficiency range is just over 30psi and they are comparable to an HE341 in size.

air air air! dont we all need more!

 

The 351 flows through a 4" exhaust flange - not an HY35.

 

I'm not disagreeing with anyone. My turbo knowledge is limited. The guy sounds like he is going to do it anyways. I was young once and never knew what the meaning of "a lesson learned is better than a lesson taught" meant. I do my best not to discourage young guys from trying something that probably won't hurt anything but wasting a little time. If I would have had one of these as a young man there is no telling what I would have tried, because I was more way more hard headed than I am now. If he does try it and it works for him we all learn, if it doesn't we all learn and he has a self taught "lesson learned". Good advise goes along way but if your dead set on going against it he can give good advise next time.

 

The HE351 has 10 years newer technology, and also has a larger turbine wheel. It is not just about the size of the exhaust housing, it is the A/R ratio. Its just like the difference between a 16cm housing on a hx-35 is NOT the same as a 16cm housing on a hx-40.

It would be much more descriptive and useful to use the A/R ratio, like they do in the gasser world, then to just use the size of the housing.

 

I'm with you now. bolt the turbo on 92smokinblacky and tell us all what you think!!!!
