I have a 2001 2500 with BD r700 Twins, DDP 200 hp Injectors, 12 mm Head Studs, South Bend Dual Disk Clutch, ECD Built P7100 Injection Pump, BD #5 Fuel Plate, ECD 194/211 Cam, BD Extruded Intercooler, Snow Water/Meth.

The truck has been tuned and pump built to and I quote, "That I should never have to upgrade it again unless I go to 13mm pump." I am confident I do not have any boost leaks, but at WOT I am hitting 1650-1700 degrees. I never stay in it long but when I come out of the throttle my egts are below 1000. I do not wish to de-tune the fuel, I want to add more air but my current question is, at these numbers how likely am I to score walls, crack pistons or any other major damage until I pull my head to do headwork and put a set of larger twins on it. Also I drive this once or twice a week its a toy not a DD.

 

not good to be running that hot...

you need to cool that thing down. how much timing are you running on the pump? sounds like not enough...

then again R700 twins are pretty small.

keep your twin plumbing and change out the turbos for a S480 and a S364 lag will increase, but egts should go down once the 64 gets moving.

 

I'm currently at 21degrees of timing. Also a 64/s480 were exactly the two chargers I was looking at getting when I upgrade.

 

yeah, even a 62 over a 475 would be an improvement, but having a built p7100 does put you up there fuel wise...

if it's just a toy and not a street truck, go big!

hell if you had money to burn and wanted to street it WITH big twins, you could do like carl did and supercharge it with twins!

he runs boost at idle on a P24v, and has twins to take over when the supercharger runs out of steam...





and he still tows and daily drives it...even in the snow.

Has boost at idle, and absolutely no lag what-so-ever
