Huge congrats to Aaron @ Rudy's Performance for breaking the current dyno record for the 6.4L at the TS Performance event over the weekend. Measured on Mr. David Dunbar's from Diesel Performance Motorsports.

564RWHP/1130RWTQ on #2 Fuel only
701RWHP/1340RWTQ on nitrous

Truck is stock with the exception of intake, exhaust, and our "310" beta tuning.

This is the same tune with which he ran at 12.6 @ 108mph a couple weeks back. Glad to finally have some 3rd-party numbers instead of seat-of-the-pants speculation.

Graphs will be posted as soon as he gets back from the event.

Great numbers Matt. Looking forward to the new tune.

Still looking for Job 1 trucks for beta testing Matt?

i'm curious about the nitrous on a dyno. do you still use a WOT switch? i feel like it'd be spinning on the rollers if you did that

Do the heads on the 6.4's have 10 bolts per head like the 6L's do? That's awesome that this amount of HP came out of a truck with stock head bolts. I don't think a 6L could do that with stock bolts.

yep. 10 bolts per head. But the metal and the size has been upgraded.

Thanks Matt. As you said, we were able to get it on the dyno at the TS Outlaw show on Dunbar's dyno. Spartan 310 Beta Tune, S&B Intake, DPF/CAT Delete, .88 shot on the last run. Amazing for bolt on modifications. I think its the first confirmed 6.4L to hit 700HP.
