if namuna did the rpm tests on the setup shown on the first page the rpm readings would be off. RPM’s are usually not measured by the wheels. if two different size wheels(tire on car and spindle) are used you get the same effect that you would as with the gearing on your bcg. where as a larger wheel will spin a smaller diameter wheel faster. and vise versa. yes MPH would not be effected, provided you have the correct equipment. but rpm’s can really only be measured by sticking the motor on the spindle which is read by the bike computer.
i guess what im saying is if you have your 5mm bit wheel spinning at 20,000 rpm, which is spinning a 10mm wheel. the 10mm wheel will not be doing 20,000 rpm. the exact rpm of the 10mm wheel would be…. (circumference of 5mm wheel is roughly 15.7mm, and of a 10mm wheel is roughly 31.4) so for every 2 rpm of the 5mm wheel you will get 1 rpm on the 10mm spindle.
Circumference = 2*pie*radius
This was what i was worried about with the error. i thought that you did it correctly. However even the smallest amt of error, can grow to a large error given the size of the test field. (rpm’s)
anyway

website: http://custombitbodys.home.attbi.comyea. all 200sx’s are fwd here. the 240sx is rear.
although i understand that the 200sx that your farmillar with is what we call the 240sx.. 200sx’s in the states are basically a 2 door sentra. but if you got the SE-R model you got the sentra with the SR20DE motor 4 wheel disks fatter tires, a spoiler and what feels to me like stiffer suspension. but i could be wrong on that one…. no turbo, but still rated at 140 hp…
yea beating civics is fun. its even fun to take an Acura Intgra once in a while.. but the best is the guy in the neon that has invested into an intake and exhaust and a suspension lowering kit… what a moron. he just took his 120hp car to 125hp.. now all it does is make noise. those are the fun ones to race.. i lose them when i hit 2nd gear. they are simmilar to the hondas, which have no torque.. all their power comes from a very high powerband. i have that same power pretty much all through 7250rpm’s… i think the civics max out at 6900 and the neons at 6300.. civic powerband is from somewhere in the neighborhood of 5000-6000, and the neon is about the same.. the sr20de band starts big time at about 4000-6500. eitherway i would love to get my hands on one of those new Mitsubushi EVO VIII’s or the WRX STI. which have both just been introduced to the states… i think both cary about 270hp…
What colors did you paint your BB shells? how many? do you have?

website: http://custombitbodys.home.attbi.comyou could be correct.. simmilar error is apparent when you put different size tires on your car. at low speeds the speedo reads correct or fairly close, but the faster you go the further off it is.. i think that would be called an exponential curve..
either way here are some formulas that they use to compute error with different tire sizes.. i think this might help figrue out if or how much error there is.
Ford Motorsports Also Uses This Formula:
(Driven Gear Teeth = Drive Gear Teeth x Axle Ratio x Tire Rev. Per Mile)/1000
FourWheeler Magazine uses:
(Old Tire Diameter x Indicated MPH = Actual MPH)/New Tire Diameter
im sure there are other formulas to do the same thing out there. hope this helps..
i found these formulas by doing a search for Speedometer correction.

website: http://custombitbodys.home.attbi.comhey panda, the reason that i mentioned the wheel size earlier is that i looked at several bike computers that would fit only 2 different tire sizes. so not all bike computers are variable tire size.:sad:

website: http://custombitbodys.home.attbi.comsr20de the removed the t here in the states… so shes only got 148hp. stock says 140 dyno says 148 go figure… the only turboed nissan in the states was the 300z. they have gone to superchargeers now for the trucks… which i believe use the ka engine..
i believe that the only came in the 240sx. not sure on the hp of it but it was a rwd. mine is fwd. its not the fastest thing out there thats for sure. but it beats hondas and is fun…
cool page on nissan engines

Quote:how did you embedd that picture into your post. I would love to know how. HOW?
jord :approve:hey, imbeding a pic is pretty easy. you first have to have your images hosted somewhere on the internet. unfortnately not all online pic hosting services will allow you to link directly to a pic. if you have your pics online, all you have to do is click on the “insert image” button on the top of the reply screen. or you can type it in by hand.
if you hand code your image link in like that it should also work.
if you want i can host pics for you and you can put your albums up on my site. i will be completely remodeling my site in a couple more days. so things will be a lot more 56k friendly….
email me if you would like me to host some pics for you.

website: http://custombitbodys.home.attbi.comauctually this does not double your steering power it only slightly increases it. there was some very exhaustive testing on this theory in the tinyrc forum. they tested using a gausmeter to see what the pull from the magnets was under dual cell and single cell. the dual cell did help, but it only added a small fraction to the stock power.
bending the spring is can have some bad FX. if you dont bend each side the same you car may not steer or return to straight again.. the best thing do do if your tires wont return or are just falling from gravity.
i had the same problem when i did my monster mod. and after adding a second steering spring it works perfectly…. and yes the magnets are more than powerdful enough to overcome the force of the spring. graphite poweder or some type of lube on the steering assembly(knuckles) also helps..

all i can think about for zero load would be to incorporate some ball bearings or someting…, but then the weight of the car its self would produce some load… unless that counts for zero load…

website: http://custombitbodys.home.attbi.comwell, how do you accomidate for the size of the wheel that is being spun by the tires.. bike computers rely usually on the hub of the bike, through a contact placed on the hub. i have also seen ones that place the contact on the wheel its self, and others that attach to the spokes… either way. many computers are designed for certain size wheels or can accomidate a couple different size wheels. some are universal… i guess it just depends on the computer.
if you place larger tires on your car than the stock tires your speedometer will be off. and the faster you go the greater it will be off.. your 15Km/h just seems kinda high for a dual cell.. (thats roughly 9Mph) many people have been doing speed tests with tread mills.. set the tread mill to 2mph and slowly accelerate it till the bit stays in one place. i have yet to hear of a dual cell hitting more than 7mph. (i believe thats the scale speed for breaking the sound barrier) what kinda motor are you using?
I think your idea and setup are AWESOME. but the calculations seem a bit off.
but i guess all of this depends on the type of computer this is..
Rock on Dude! have you thought of doing up a comparasion chart for different motors and battery configurations, and gear setups?

i talked to a rep from microspeeders today. they called me.. hehehe
She said that they are still working things out with the FCC to be able to sell here in the US. so if you want one your best bet would be to buy from a site that sells them instead of buying directly from Minispeeders… this also means that there probably wont be anyone over here carying these for a while.. unless somone has a buyer over there… and i think i know of one US site that might have a buyer… rcmod…either way from the sounds of it they are fairly new.
the person i talked to was from the states… i wanna job in germany!! that would be so cool!
i guess i have to start to speak german…

remember also. just because he has sold something dosent mean that there will be feedback… im on ebay also and some people just dont leave feedback. but its usually new people, who just havent figured out the system yet.. eitherway i dont think hes really selling any…
since it dosent cost anything, hes probably just telling everyone to take off the body… shazammm its faster….

but i noticed that on those “sportwagens” there is a small hump on the hood. i havent seen that on any bits? is there one that i just havent seen? if so which skyline is it? i have the skyline history set and its different from all of those. and i also have the shen skyline which i think looks a bit differnt.. is this a different body alltogether?
