[QUOTE="SPE, post: 965934, member: 4007"] **This is copied from our Facebook page** With the posting of our truck making 1025hp on fuel only, we've had many of you asking questions so we want to try & address them below. Q- Why is the torque number so low? A- That's because of the big chargers on the truck. The turbos are just lighting & the 6.7 can't fuel past 3800rpm but we are working on that. Q- What's the set up on this truck? A- The race truck is now running a 75 / 106. Both are Borg units s400 and s500 based. Q- What kind of shifter is in the truck? A- That's a custom one-off shifter designed for & only utilized by SPE. Q- What engine is in that truck? A- It's still a 6.7 Powerstroke. We have no plans on putting a 6.4 in it. Sorry. Q- What was the 926hp I saw on the previous run? A- That was us running it in overdrive. The transmission didn't like that with the load required to spool the chargers properly. Q- What's all done to the engine? A- SPE Stage II Long Block Q- Whose dual fueler are you using? A- SPE dual C4 .2 high pressure fuel pumps (one of only 2 made) Q- What injectors are in it? A- SPE 60% Over Q- What dyno settings are you using? A- SAE with a smoothing of 4 Q- How much boost does it make? A- The pull was made with a street boost level of 90psi & the dyno load was constant through the pull. [/QUOTE]
