I'm running a he351cw turbo on my 1st gen engine. It runs a little high in the egt dept. Does anyone know of an upgrade exhaust housing for them?

Maybe banks? kinda pricey though. Or maybe call some of the aftermarket turbo companies.

Might try posting this in the 1st Gen section for more help...

That is an 04.5 turbo he has!

I''m running a 3rd gen turbo on it like moorepower said. Just looking for info. I thought you guys could help me out.

I do not think there is a housing upgrade. I know that the waste gate hole can be opened up for more flow. Do a search on the thread about converting to an HE351 turbo and there is alot of info and some pics of enlarging the waste gate bypass hole. It is a very long thread, so it should not be hard to find. Are you running an adjustable boost elbow? What kind of boost numbers are you seeing?

There are no bolt on upgrades. There are a couple of companies that are modding them, but its not cheap.

Exactly WHAT are you defining as high EGT's and under what conditions?

dkimmel

1400 deg plus. Under full throttle blast or on the pulling track. It cools down to 600 deg though. I can get 43 lbs boost of of it.

A friend with a pulling tractor took his turbine to a machinist to have the groove cut open a little and he said that did the trick. The best guy to talk to would be Piers Harry. I don't know if he still owns PDR. I remember someone saying he went to work for some outfit like BD or Pacbrake but I think he is still playing with turbos. Craig

Thats probably about right for that turbo. It definitely suffers from DP and heat build up in the top end if your pushing a lot of fuel. Not much you can do with the exhaust housing but go to a bigger one.

I'm still running stock injectors which are small. biggers injectors would mean more heat. Maybe if I restricted the wastgate air flow it would help.

Thanks for the imput to all.
