Silver Bullet Tuning makes 625hp smoke free.

Meaning he could use over 600 HP continuously, all day and not have any EGT issues, even at WOT ?

I don't understand this then.



If you can get it hot (1500F) racing to 110 MPH, why wouldnt it get hot towing ?

600hp is at WOT. There's absolutely no reason he'd be running at WOT all day long. That's not realistic. Remember we can change how it fuels at each point of the pedal.

As explained above...NOBODY tows at WOT. I built the tune to make power on the street...if it needs tweaking to keep the EGT's under control...then so be it.

His turbo, injector and tuning choice will allow his to tow all day with a truck that makes over 600hp all day long. Its a simple fueling adjustment (if needed) to pull fuel back when under HEAVY load to bring the temps down (IF THEY ARE HIGH).

He may not be at WOT all day long, but give him a 14,000 pound trailer and an 8% grade and he needs 400 HP to maintain 60 MPH. Throw in a headwind and you are at 450 HP. Can it run there without EGT issues ?

Thanks !

BTW: I think what you are doing is awesome and the fact you can get so much power while being smokeless is double awesome. Great work and thanks for sharing.

Yes...the turbo map is favorable to towing heavy and keeping temps cool. My interpretation of cool is 1250-1300*@40psi

Alot of how something tows is on the drivers seat....foot control, gear control etc...I can tow 14,000 with my 66mm if I want, I'd just need to adapt my driving style to be conducive to what I am doing.

Les,

If I hitch up 8 regular reindeer and one with a rednose and put one fat bastard in a sleigh going over the Himalayas with ALL THE TOYS IN THE WORLD, which reindeer would run out of breath first?

Now, lets make it 10 reindeer and lets go a little faster, now which reindeer runs out of breath first?

Do you use the turbo map or do you use boost as a limiter ? Or both ?

What kind of boost can you get with the VGT (with decent timing) at 1700 RPM ?

I cannot wait to start tuning my 6.7 !

Thanks !

Unfortunatly here in California we are limited to 8 regular raindeer and one red nosed one.

Adding another would make it much easier but smog dictates and Highway Patrol says otherwise

Both...I build my setups to utilize the sweet spot of the turbo map for DD and towing and the right side for peak hp goals.

I didn't get the reindeer analogy. Just saying.

I understood it as rich was saying that twins are the best of both worlds. Here in Ca, smog laws won't allow for twins, so we need to do our best with a single turbo.
