Yeah, I will be changing it to one zip tie. I read the rules wrong when I did it. I thought it said 2 zip ties minimum, but it says 2 zip ties maximum! Lol
What size is the RCD IHI? I had a DTS billet 66 IHI and think I was about 650 with 45% over's and Exergy 10mm pump and I had plenty of fuel.
Here's a vid of my truck last summer. I actually broke a stock axle when I unlocked the converter at the end. Took 1st place out of 28 street trucks...
I ran 4:10's and 35" BFG's at about 650hp and 3rd gear last year and
would hit my rev limiter at 4,300 on loose tracks. If I would have ran that set-up again, I would have switched to 3:73 and 3rd gear or 4:88's and 4th gear.
