I have a friend that was in the DPC in 13, his 07 cummins made 900hp/1675tq, he drove it around quite a bit and ran it at the local 1/8th mile a bunch, every now and then he would get it hooked up and it would run a 7.10sec 1/8th.
had a hard time keeping a trans in it even though suncoast was a sponsor, it became quite a hasel to pull the trans and take it to florida every time something went wrong.
