looks awesome!
fill us in with a report card on how she is performing, any things you did that you wish you would have done differently, stuff you didnt do but wish you did, etc. if you dont mind. I am curious to see how its doing for you.
How does it behave while towing? how heavy are you, what gear and RPMs are you running?
Sounds awesome, thanks for taking the time to post it all up!
A little update for some of your questions.....
I have around 15K on the motor now - I don't use her much, I have made a few changes & updates sense first built, went from a 12cm turbine hsg w/12 blade wheel to a 14cm 10 blade wheel this gave me more power and a lot less egt heat, the feel on the road towing went from good with the 12 to great & easier with the 14.. turbo - Holset 35/40 - 10 blade turbine wheel / 6 blade pro comp wheel , boost set at 25psi but never use that much...
Installed a CAC.
I now have a WMI system but rarely turn it on, have a 14gph nozzle in it right now.
When towing the horse trl and 3 horses the rig tops 20k total. I tow in 5th gear mostly and I drive by the gauges, I can see high egt's above 1100+ at times but not often.
My IP is set at 100cc now, but I have NEVER went close to WOT towing this heavy, but I haven't been up anything bigger than a 3 mile 7% grade loaded yet either.
With the 12cm hsg, the motor felt like it was "twitchy", just waiting for more go fast petal, had 5-7 psi cruising at 75mph empty, had instant 25psi boost anywhere over 1500 rpm's. Motor always felt like it was ready to go more than needed power wise. With the 14cm hsg, I still have instant boost over 1700rpm's, motor sounds more relaxed and at ease now, pulling power is much better with the 14 hsg & the 10 blade turbine wheel ( hx35 turbine side )...
The rockers took about all the rattle away, once the fuel system was bled again the idle went back down as it should be.
I guess, all in all, I wouldn't have done anything different with the ceramic coatings other than maybe used a little more. I truly believe, NO- I KNOW that a few of the coatings I used are directly responsible for how well my motor handles the high egt's and other temps, I do know that I have NO heat trouble at all, I blame this solely on the 3 different heat barriers used inside the motor with the coating in the exhaust & intake runners & pistons being the highest contributor to getting the exhaust out and not allowing the heat to soak into the motor and keep it heading out the pipe and not in the motor, this I will do to ANY other motor I build again... I can for sure make this statement because almost everyone with a 6.5 has some kind of "too much high temps" is almost normal as we all know.
Truck has 3:73's, nv4500, 245 rubber.. towing my setup interstate speeds around 65-70 with ease but it gets my rearend hot quick being a 3/4 ton so I stay around 65 or so when I think about it...
Member "Diesel Nut" took it for a spin loaded a few weeks ago, 90* , 60% humidly, 20-30 mile ride on I-26 here in the upstate. he might give you another prospective if he see this...
Fuel mileage during the break in trip was 20-22mpg, empty and cruse set at 75.... I haven't checked it again yet, we are taking another road trip of 2500 miles the first week of August so I will check it again then....
One thing I really wish I could figure out how to prove is the thermal barrier used in the runners and how it block or stops the exhaust heat from transferring to the heads, I did do a test with a coated piece of metal, coated one side, then stuck a torch to the other side to simulate exhaust flowing across it and I can't ex-plane how it works but very very little transfer of heat occurred.
If I had it to do over again, I would start with a P400 and do the very same thing again, maybe more coatings.. and have it in a 3500 cc.....
