Since Strokers are the topic......

[Garrett Ellison]

Are you using the geometric ratio 435 with the 6.68:1 first and 3.34:1 second for a 6.55 driveline ratio? Do you have any video of that? It sounds like a blast!

Thanks a lot for that info! I have Nitto 33x13.5x15 mud grapplers.
I have a 408 stroker, forged scat crank, H beams, forged CP pistons. 9:1 compression. Trick flow heads, Harland Sharp rockers and a street solid roller cam. Topped with a little 162 B&M supercharger pushing 3 psi. Dyno’d at 574 HP & 580 Ft Lbs. 6” crank pulley and a 2.5” driven pulley. I’m spinning the blower fast, I’m a little concerned with the heat of the blower the length of the track. Lol. Maybe it won’t be a problem.

I would research running a water/meth (washer fluid) injection system on the blower inlet. I know it works well for a procharger, I imagine it would have to help out with the roots blower.

The blower I’m not sure of. Everything I’ve been around is n/a. Depending on your dirt conditions you may want to go to an all terrain tire. Aggressive mud tires tend to induce a bounce Are you hanging weight forward from the front of the truck?

Final drive ends up right around 27.5:1 with the axle gears. I don’t have a video of mine. I only got it going last year and was only able to pull it twice. Plenty of videos of the ford I help with

I was looking at a kit. I would like to run some type of water meth, not sure if I have to change the tune/jet for it. Probably. Got some reading to do.

Aggressive tread makes sense on the bounce. Thank you. Maybe I’ll swap to an all terrain.
No weights on the front, that’ll probably put me in a class where I couldn’t be competitive, I’d get my *** kicked. Lol
I’m sure the blower and engine mods will put me in a special modified class too. I was hoping theyd let me run what I brung, just to see what it’d do. The track is local, once a year event. I’m sure I could get in, talk to a few locals who run.

this is the clutch, after all I mainly built it for street duty, and off road wheeling at Local Hollister Hills OHV park. They have very intricate trails.

I gotcha. It’s not a dedicated pulling truck. Should do well. Just make sure to get as close to there max weight allowed as possible and as far forward as possible. Also block the rear end. Wheel speed is your Friend when pulling.
