hx35 blowing up after 35lbs boost?
 

umm no way. i have a 97 cummins with no fuel plate k&n intake 5 inch straight exhaust and air dog system. i go over 35 psi all the time and in every gear cept first and second. i hit 53 lbs boost in 4th gear right b4 my input shaft snapped at clutch. and i have run 50psi pulling a trailer and held it there for few seconds and did nothing, egts got to 1760*f tho. but i dont think u will have a prob with it. and mind you i have 407k miles on mine and runs great.:jump:

Sorry I didn't see this earlier. You are correct, my S400 came off of a 12.5L Deere engine.

Everybodysays after 35 or so that there out of there mapping an are just pushing hot air into your motor. Idk about all that my cousin an I were hitting 45 48 before timing. But pyros got toasty. I know you can do it just not recommend. And Thanks you've been a great help.
