Hello Again all,
So I have all the parts I need inbound and hoping they are here in the next couple days. I have done a bunch of reading and I have a couple questions I have not found answers to and was wondering if anyone has any advise?
1. I am building the car in what I would call "tarmac rally spec" for unprepared roads and parking lots. I ordered CVA's and sport tuned springs. What piston would you recommend and with what weight oil? I am guessing I will want a bit softer set up for fairly low traction. I already have 30 and 40wt shock oil.
2. Gearing- So I still love flying inrunners in gear boxes on my planes and am pretty darn good at getting the gearing pretty decent right off the bat but I am a newbie to this whole car thing and not sure where I should start. I am going to run a old Novak 17.5 Havoc Sport, basically it is a 17.5 Blinky set up. I have not ordered the YR motor mount or the Speed Tuned Gears yet but it sounds like the stock gearing is pretty short. What would you think a good all around FDR would be for bashing that would produce a good turn of speed but also offer good grunt off the line all while keeping the motor "comfortable" temp wise.
I am looking forward to putting it together once the last box from Hong Kong arrives.
Love the DTM bodies above.....that was some great racing back in the day. I am a huge Audi fan (I have owned a Ur-S4, B5 S4 and currently a B6 S4 plus I own an original '84 Ur-q) and in my searching I found an Audi V8 DTM shell that looks sweet but they want like $70 for it....Maybe one of these days I will be feeling a bit flush and put it on order.
Thanks.
Cheers,
Jim
For 17.5 gearing, somewhere in the 4.2 - 4.5 range depending on the size of your running space. I am running a Trinity D3.5 17.5 with timing advanced all the way to the stop on a carpet track that is about 70x40 feet and running a 4.42 FDR. Temps after 5-6 minute race is staying around 105 degrees, but I am running a fan. The car jumps off the line and is pretty quick in the space. If you are running in a larger area, you could go a little lower on the FDR. Or, if you don't crank your timing up, you could run a lot lower FDR. Its up to you how you want the car to behave, but for me, I had too much torque with the lower timing setting.
Whatever you do, keep a temp gun handy and check after a minute or so after every ratio change or timing change. Keep it under 160 degrees and you should be fine.
