My objective is too reduce egts,

what are you doing with your truck? Towing?

 

Yes I tow a fair bit for liesure.

Is 1300 f for a period of 5 mins safe?

 

the problem with high temps for longer periods of time is even if you dont blow the head gasket you may end up with loose valve seats. Lower temps say in the 1000*-1200* range would be more of an ideal range. that being said I hit 1400* for a a few seconds all the time. If you want to set up the truck to tow really well a 62/12 or a 62/14 would be best I would think. a BD super B would work reall well too. All 3 will work well up too 450HP towing. Im sure some others with more experiance will chime in. Im just relaying info that I have read on here on the turbos.

 

I dont know that steppin up to a 14 wouldnt be a better idea.

Call Paul at HTT tomorrow and see what he says.

 

yeah, if you're towing, more turbine might help...

but... if you're towing? best thing you can do is twins!
