Toyspeed virtual drag race competition. *CLOSED FOR NOW*

[riddles]

Some interesting numbers although I would have to debate the last couple.

According to the calculaters possted in the rpm to speed thread The car has a theoretical top speed of 270kph (larger rolling diameter than standard @ 261kph), I know it has been up past 200kph so a 170 top speed just isn't right.

From the 200l of gas that went in over the weekend I got 2,100km and still have about half a tank left, so closer to 9.5l per 100km for the consumption.

[RomanV]

Well how sure are you about the coefficient of drag? This is the biggest factor to top speed, and IIRC you said it was .4, which is rather high!

Your theoretical top speed doesnt take into account that you may not reach 700rpm in fifth, if the car cannot push through the aerodynamic drag.

This could also affect your mileage.
However I will double check the numbers when I get home.

Also, on some other tracks which I had a play with but didnt post, your car ended up in the top 2 or 3.

[Emperor]

I cant... Dont have enough info.

And I CBF'd searching for the skyline info that your missing. Maybe if it was a toyota, and easy to find.

What do you need? The gear ratios?

[RomanV]

Gear ratios, wheelbase, car height and car width.

You'll be able to find the wheelbase, car height and car width here:

But your on your own for the ratios.

I have a program that simulates quarter mile times, as well as a lot of other things.

Any chance you could zip it and email it to me at dave@dave.not.nz(munged) change not to net

[riddles]

Yeah, the .35 cd was hard to find, got it off one of the american forums. I know it may not be possible to get to the theoretical top speed but have had it approaching 220 in 5th (guesstimate since the speedo only goes to 180) on an slightly uphill straight before I backed off and there was still plenty of give. It eaisly gets up to 150-160 in 4th and my speeds at the drags were 149-157 in 3rd and just getting into 4th for the 157.

[Stealer Of Souls]

Does displacement matter much in the calcs program...
Just realise that I originally put in 1598 (was looking at something else at the time oops...) in stead of 1587...
hp and torque figures were still about right though...

[RomanV]

Riddles:
Aaah okay.

Yes I agree that the indicated top speed was quite low in your case.. I think something must be amiss. Will double check when I get home.

SOS:
Yeah it does, it helps work out what the torque/hp curves look like.
But the amount of difference between those two numbers would be SFA.
Perhaps if you said it was a 6 litre 4AGE it might matter a little more.

Can I gueest a bit of quoting in your posts?
I have no idea who your replying to, and imagine that others don't know either.

Sorry, dont have heaps of time to reply at the moment.
Yep, I'll send you the program, but not till later tonight at the earliest.

[boxxy]

I'd love to see some Toyota vs Honda comparisions. Like 20V vs B18c etc.

i wouldnt... i think those dirty dirty hoondas would pawn us (20v owners)all

I havn't been able to find gear ratios yet, it'll be interesting to see how a car designed for nurberguring goes against a couple of toyotas

Updated!

i wish I got 6.2l/100kph

Its more like double that

[durty starlet]

yeah, my gas consumption is heaps worse than that

[fuel]

My fuel consumption is about the same as posted - although the top speed is a bit on the high side - the best I could do was 165km/h on a long long straight (not on public roads of course.. noooo).

I'm amazed that I'm only 0.01 of a sec quicker down the 1/4 mile than an automatic AE85. My car isn't even that much heavier, and has more power and torque.

[RomanV]

Riddles.... Ive found out whats wrong.
I entered your wheel diameter as 17cm rather than inches.

this will more than likely drastically change your results, so I will rerun them for ya.

[RomanV]

All cars entered now, first page updated.

Note: changed Instead of suzuka, I have now listed slalom speeds.
Some interesting results there! really mixes it up a bit.
WTF is helbnds car doing up there?!

[madaltezza]

wish my car did 14.95 secs at the drags and the 230sumthing km i wish 2 my car stops at 192 in 4th still got 2 gears 2 go arrrrr
