| Griz's snowbashing motor with video now
Well it finally ran on the engine dyno last week. I have been working on this for a long time, the old saying "horsepower costs money" is very very true. The specs Coast High Performance 393ci stroked 351W main girdle, steel crank, H-beam rods, forged SRS pistons 8.5:1 compression custom Iskendarian Racing camshaft, roller lifters, Comp cams steel roller rockers World Windsor iron heads, 2.02" intake 1.60" exhaust valves Every ARP stud and bolt you can buy high volume oil pump Holley commander 950 injection, Accel 750hp fuel pump, MSD TFI distributor (so the computer can control timing), MSD 6AL AND a Holley 174 powercharger roots blower with Price Motorsports Engineering intake manifold adapter The numbers: RPM HP Torque 3700 376 530 4000 407 534 4300 442 540 4600 472 539 4900 495 530 5200 520 527 5500 529 505 5800 538 489 These numbers were before the dyno was fully set up so he couldn't get numbers below 3700 rpm. We just threw a 750 cfm carb on it, locked in the timing at 18 degrees, threw the big pulley on the blower, and thought we see what it would do. I figure it is making about 3 psi of boost right now, the goal was at least 550hp at this altitude. The above number are corrected for sea level. I caint wait to see what happens with it in the Bronc. |

And here's why I need the horsepower. Snow, and lots of it. I love snow bashing more than anything else. Plus it'll be fun in the sand.

For those who may not be familiar, snowbashing through 4 ft of snow requires flotation and wheelspeed, much like mudding. In order to get enough wheelspeed in 2nd gear (1st gear will just break stuff so I will be starting out in second and shifting into third) I run pretty high gears. It takes alot of horsepower and torque to keep the tires spinning fast enough to float across the snow (again, much like mudding). My rig is setup very different from a rockcrawling rig, I run a C6 auto with 2.46 first, 2.45 second, 2.34 Bronco T-case gears, and 5.13 axle gears. That means overall gear reduction in second is only 29.5:1 and third is 17.5:1. but it's all fun right? Last edited by Grizzly4x4; 04-04-2006 at 11:56 AM. | ||||

Sweet set-up Griz, can't wait to see it all set up and putting that power to the wheels. Not very many people know about Bald mountain its a blast in snow! I use to be a resident of that area.

Hey, I finally uploaded the video. I know, I'm slow. I had alot of trouble with the guy who was supposed to tune the injection on the dyno so I finally just took it back. I'll have to tune it on a chassis dyno. Enjoy. http://video.google.com/videoplay?do...23102586&hl=en |
