had flux 4s. smarty beta 4.2 got 736 then w tst 5 2 800.5. i think the truck has about another 20 hp or so. didnt have enough time on the dyno to play around w the tst much. gona do studs in a month or so. so far they have stood up fine. highest boost is 80-85 w tst but i dont run the tst much at all.Kman9090 said:With your setup I would be looking into some supporting mods. I would do some studs and some 60 pound valve springs. Some people get lucky though running that much boost and others are not. Depends on how your luck goes. Personally I wouldn't go much past 45-50 on stock bolts unless you tightened them daily. How did you get 800 hp with stock injectors and just Tst Smarty combo? What levels where you running them on. I'm only running about 600 out of my truck.

it was a dyno jet 248Summit said:on stock studs,, i dont see how this is possible. and what kind of dyno made these #'s ????????
there is part of your problem! Get on a real dynotwinmega06 said:it was a dyno jet 248
oh, I am sure the numbers are for real, given what is done to the truck. Now, he just has to worry about how long that gasket is gonna hold with stock bolts. Personally, I think it is a great test to see how far we can go with the stock bolts. I personally opted for studs when I went over 650 HP. However I have a friend that hammers his truck daily at 60 psi of boost with a s300/s400 twin set that I built that makes over 600 on fuel that has not had a lick of problems either with stock boltsgetnitbo said:i call bs!!!
According to F1 diesel's website stock springs have 80lb. seat pressure closed.kino_fab said:I thought the CR's came factory with 60lb springs. I would figure he would want atleast 100lb.
