Spool is in for modified purposes. Oneway definately in 19 turn. I want to see how much of a difference the pre-made spool is compared to the one made from a regular diff.

Okay if the spool benifits for mod. and one-way for 19t. what do you guy's recommend for stock.

Rear wheel drive only. J/K

The way I look at it is Spool for mod, spool or oneway for stock (driver preference) and definately a oneway for stock. This is for rubber tires on med/high grip asphalt.

Our boards are pretty tough, so I was thinking about some spare A-arms, things like that...

The plan is pretty simple: Run it plain stock, and see how far I can take it. Later on, I'll maybe try a spool and/or a one-way.

Is there a recommended setup for carpet, rubber tires. Stock class exclusively. And no tire sauce at all. I'll probably start out with a boring-looking, nice handling Stratus, or something like that.

I do have a reasonablt selection of Schumacher springs, but I believe I'll be using my HPI springs, since I got a much better selection of these

Thanks.

gGreat thanks for the info as that is the type of surface I race on. But it is a tight track too.

Default MI2 Setup

Hi guys hoping you can help with a setup. We have a national title coming up in November and need abit of info on setting up a MI2 for my son (13 years old ). He ran the state titles with pretty much a standard setup for the manual just changed spring rates (4th place in the A final should have been 3rd but thats another story). He runs mod, will be using around a 9 to 10 turn motor on foam tyres 40f/40r shore or 40f/37r.
The track runs around 10-11 seconds a lap
Would also like to know what to change eg roll centres, diff's, shock towers, I'm ordering the alloy rear hubs just need to know what else to order
Also here is a link to a pic of the track.
Thanks
John

check out all of the rubber tire carpet set up's on www.gearchart.com Mo posted some good one's on there as well.

Stock, mod or 19 turn is all personal preference. I ran a spool in stock at the region 12 race in hisperia and I had the fastest car on the track. For the last couple of race days I have been switching between the two and they are both great but the spool allows me to out brake people in some corners.

Quick question for all, why do you run the 20t instead of the 17t? Wouldn't you have better accelleration with the 17t? Or do you lose to much top end with the 17t with current motors?

Tao3 - I have no experience with foam tire on asphalt so not sure where to start for setup.

Mopar - To me, a ratio is a ratio. If you ran the same overall gear ratio with the 17 tooth as you did with the 20 tooth, your car would have the same acceleration and top speed. If someone could explain to me how a 2.0:1 drivetrain has more punch than a 1.8:1 ratio in scientific terms instead of just that it "feels" like it, then i will buy it.

What I was told is it shortens the rear belt life when using the smaller pulley. Thats why you always see the 20t being used.

Mopar- for the most part Jack is right. Where the difference in internal ratio can make a difference, is in efficiency, and acceleration. As far as efficiency is concerned, the 20t should be more efficient, because of less dynamic binding (e.g. in the belt teeth wanting to climb up the face of the pulley under acceleration, causing a mismatch in pitch). And for partly the same reason there is an argument for using the 20 tooth for better acceleration. However, a smaller pulley means less rotating mass which = faster spoolup, and quicker acceleration. This is minimal with todays components because of their light weight, and the abundance of power with newer motors. One other advantage the larger pulley has, is that the RPM's on the layshaft are reduced, and this makes the car (in theory) transfer weight more easily left and right. Although all these things effect the way your car runs, they are all minor and should have less effect than just making sure your belts aren't loose. -Jeff

yeah thats what i think too because wen i went indoors i did hit alot of things with the diff,i think with turning it into a spool just finished it off with just driving the thing. bob
