Hey everbody. Im new here DTR seems like a great resource and its nice to find so many diesel junkies....
i just bought a 93 diesel dually 4x4 auto .. the pyro is installed after the turbo onto a 3" DP .. under full load 22-25psi boost(@ manifold) pyro temp climbs to approx 800 +-50 ferhnieght after a minute or two (reaching approx 65mph)... what is max safe temp after turbo for these things...
this was done with no extra weight --unloaded --

torquefan

I think most people consider 950 deg. to be the maximum safe temp AFTER the turbo.

pre turbo 1350 is safe but post turbo i think torquefan is right 950

I'd drill and tap the manifold, plug the exhaust pipe, and get a REAL pyro reading. The t-couple being post turbo is useless, IMO, unless you use it strictly for cool down.

ya im begining to think thats what i should do ... ill keep the post turbo and install at the manifold as well.
