Engine/Transmission (1994 - 1998) Well beyond efficiency of hx-35...

[CVasa]

I've been pushing my 35 for some time now, not to mention my head gasket. I recently bought a 14cm wastegated exhaust housing, in hopes to cool my egt's and reduce drive pressure. (havn't installed yet)

On a mustang dyno i made 348hp-822ft/Lbs. at around 38psi.

EGT's are uncontrollable over 2800rpm.

I'm just wondering how much a housing will help me.



Also This summer i'll be looking for a different charger, possibly a Super B special or similar unit.



I would appreciate any and all input. I'm sure there are quite a few others out there, pushing their 35's to the limits, looking for budget upgrades, also.

My understanding is that housing may be good for 100 degrees or so. Probably not nearly enough.

you are so pasted a 35 I don't even think you will see a differnce with it.

CVasa, Welcome to TDR

We are pretty close on power. I just dyno'd yesterday at 355hp and 777 ft-lb torque with my setup (w/o meth). although you do have a bigger (215) pump and DV's. My injectors are a little larger. My egt's are also pegging the gage and I'm on the stock turbo pushing 40 psi.

Heres a post that has some info on turbo selections:

I still have not desided on what to get. I've heard of a guy close by to me that builds turbo's from the shop I dyno'd at. I plan to visit with him and see what he recomends. I would like to hear what your 14cm housing does for your temps & spoolup. Is your exhaust open? Size? Where is you plate positioned?

PS: KDP also got me a couple of months ago with only 73K on the OD.

I run the 14cm on mine. spools like stock pretty much. Temps still get way hot. With the combination of the 14cm (with a banks WG actuator), and the dodgezilla compressor, I can still peg the pyro pretty easily.

Before the 370's, it would still get hot with just a 10 . 030 foward (350hp or so... ).

With the injectors and other junk (546hp), it gets really hot.

spool is incredible though. and I have the wastegate pretty loose, and boost elbow open as far as it will go and it still hits 40-42 psi pretty easy.

what kind of machine work is required to fit the 6 blade 60mm compressor on the hx35. some kind of clearancing of the bearing race?

must i send it in to htt or can my local machine shop do the work?



Also what kind of gains can i expect from the compressor upgrade, and which exhaust housing should i try first.

I upgraded my HX35 with the new 7 blade Super 40 housing and wheel. The wheel is 4035879 and the housing is 4039617. I got them from Gillett Diesel Service. It came with the directions for machining and I had it performed by a local machine shop. It only required increasing the pocket diameter behind the wheel. I am still running a 12cm exhaust housing. After I added a needle valve on the boost line, (same results as the boost elbow), my EGT gets to 1300 at 36psi.
