Tires / Golf cart tires and gearing help.

« on: May 08, 2018, 08:45:35 am »

Hey guys,

I'm planning on using 8x8.5 golf cart rims for the rear of my mower with a 18x8.5x8 tire.

I currently have a 8 inch engine pulley and a 2 inch trans pulley (700 peerless) and but I don't have a rear axle or sprocket on yet.

Its just going to be a back woods circuit track racer not an oval track racer so I need both speed in the corners (wide and sharp) and speed in the straits. (some long sweeping turns)

Can you guys help me find the right ratios and whatnot please?

(I might have to shift on the fly with a 700 which I know isnt a great idea but maybe it will work if I shift really slow and really let the RPMs drop?)

Chassis / Does brake caliper size matter for the thickness of the Disk?

« on: March 06, 2018, 09:05:04 am »

I'm setting up my breaking system for my racing mower and this is my first ever build so I have no idea what I'm doing. I want to buy a Honda GY6 brake caliper off of eBay and a 8 inch brake disk (8" brake disk - gold) off of BMI carts that has a .16 thickness. My worry is that I'll buy both of these products and have the brake disk be to wide and not fit in the caliper. I have been searching for what the max thickness of brake disk is compatible with that caliper is but I so far haven't found anything. If anyone knows anything about this lil problem of mine, could you please shoot some info my way? Thanks!

(Also I know that these aren't going to last long and I know they are super cheap but I'm not planning of thrashing this thing super hard and I'm a high school student with no money so I can't spend $200 on a break kit.)

Chassis / Mower frame question.

« on: November 16, 2017, 08:46:38 am »

Would it be possible, or more so a good idea, to make the frame that the body of my mower will fit over and then drill holes and bolt the two together? I was going to weld them but together but then it might be hard to keep it from distorting from the heat and so on. Also I think it might be better for maintenance. (this is not going to be a racer so those restrictions don't really apply to me.)

Coffee Shop / Anyone use the 708cc yet?

« on: November 11, 2017, 08:09:13 pm »

Hey I'm just getting into the racing mower game and I'm starting off with the classic 12.5hp briggs but I'm just wondering if anyone has used the 708cc v twin from the good ol' harbor freight? There ain't no performance parts for it but that doesn't me no one has tried it yet. I personally have no aspirations to use it because I'm kinda interested in the 14hp boxers but who knows maybe I'll drop one of those in my mower. Anyone?
