Obs build

[bluedge8]

So what should I do to "help prevent" shattering the bottom half....without dropping another couple grand$$$$.?

I plan to detune it a bit just to be cautious. But besides that.

Think about a different turbo.

I have a stick in mine with the same setup and its plenty laggy. No need for another turbo. If youre really worried even after conservative tunes put a bigger exhaust housing on it

I figure conservative tuning where the hot tune wouldn't be more than 500-515.
Hoping that would be good

I've been told by many people (including matt at gearhead) stock 7.3 internals are good to 650hp driving it everyday. If you make 550hp I'm sure you'll be fine. As long as you're not ripping it everywhere.

 

[97stoker350]

Well I know from personal exp that is untrue. I'm in no way challenging matt's knowledge but Plenty of people on here can prove bottom end failures well below 650. Now maybe he means with his tuning it will live but how will it drive? Again I'm not calling him out. I've never ran his tunes and I also can't recall a case when a truck blew with his tunes.

tuning and skinny pedal makes a big difference.. me, id install the windows mod on the initial break in run.. lol

live life full throttle

i like what your doing, ive seen several bottom ends hold together with that power level easy, key to it is a very good tuner. someone that has a reputation for tuning trucks of that caliber and keeping them together. There is a local 7.3 turning 715+ on spray with stock rods and tuned by dyno proven and its still kicking for the long haul.

It's all in what rpm the power is made. The 468 spools very low and make huge power around 1700rpm. While something like a 471 will make power up around 2300. Keeping the power later in the rpm range will help keep your rods in your block!

It wI'll be a little more laggy but thats the price you will pay to make reliable power. Or spend $$$ to build it.

Someone did mention this earlier, the quote said "larger charger"

 

[snydermotive09]

Any recommendations on a good place to get tunes?
I've had tw from the start but hear a lot of good about gearhead, dyno proven, php.

 

[FrankTheTank]

TW and PHP are the grandfather's of 7.3 tuning. But each had their own trade marks. I don't like TW's touchy throttle. Dyno proven doesn't tune to a TS chip I think, I know they don't tune hydra chips. Gearhead tuning is very similar to PHP in drive ability and can be almost smokeless. Don't forget about swamps who prolly is the only tuner who uses cylinder pressure montero ng equiptment while making their tunes.

You really cannot go wrong with any of them, but it's all in what you like and who will meet your needs

DynoProven tunes on the TS style chips. They also tune on DP. Jonathan does not tune on the Hydra.

IMHO: Once you put in modified injectors, every truck should be lived tuned once modified.
