looking for some timing help on 12v puller

[bhfr-cummins]

well like it says I have a 96 dually im running for a race/puller. what im trying to find out is what would be the maximum amount of timing that I should run for the best possible performance. here is the setup.. 84 mm s400 turbo, pdi exh mani, 181/200 cam, titanium retainers, commonrail lifters 60# springs, oringed head, arp 425s chromoly pushrods. the 7100 is a 180 version, it has .093 holders, lazer cut dvs 6000gsk, no fuel plate, 152degree angle 5x22 injectors... stock crank and rods the stock pistons have had .050 cut off electric water pump and 200gph fass.. right now the pump is set a 25 degrees and I know I can run a lot more timing, so I was seeing if I could get some idea on how much I can run on this thing. I know that I wont be able to get the exact setting but I was just looking for a reference to get a good starting point, thanks for the help

32 degrees is what we Run on the 95 puller I built.

yea I was thinking I would start somewhere around there but wanted to get some inside info first, thanks

I run 30 and have a similar set up.

If you don't mind me asking, what size turbo do you have, and if similar does it stay on top the turbo well

we are running a 66/83/1.00 t4 s400

Ok see the turbo im running has a 84mm compressor wheel I will get the specs and post it

Id start around 30 and go up a few degrees at a time until it falls off then back it back down a bit and leave it... $.02
