1. What is the weight of the car + a 160lb person + a half tank of gasoline? (and full tank)
2. What is the stock tire width?
3. What is the aspect ratio of 3rd gear?

Thanks alot!

Mike

P.S. - If you guessed already, this is for a road dyno run

P.P.S - ON A CLOSED COURSE OF COURSE!!!

 

Well, the MT car weights around 2975 with full fuel, take maybe 45 for half a full tank, and +160= around 3090, I think.

 

excellent, thanks!

now i just need the tire width (which i can probably go measure myself, haha) and the ratio of 3rd gear

 

tire width? stock rim? I think is 7.5, the gear u can find in the internet.

 

well the stock tire is 215/45/17..

In the hour and 21 minutes in between your two posts you could've found it all out with a little googling...

 

yep...

 

215/45/17, which is the width and in what units?

3rd gear is 1.413

also, what is "final drive" in terms of gearing and transmissions? for the 4spd auto it lists the ratios of 1 2 3 4 reverse and "final drive"

 

215 is the width in mm.

45 is the sidewall's aspect ratio (45% of the width)

17 is the size.

 

awesome, cant wait to dyno it tomorrow!

thanks for the responses

 

why u needed that info for dyno? got a laptop dyno?

 

well, pretty much, its an obd2 dyno running on my carpc
