whats folks experience?

 

Post up the pic of your top speed on it then,lol
This is always asked when someone has been playing on there own private test track

 

had the car out last nite gav and it was mental...

The way it gathers speed is unreal.


Dont think its too wise to post up the speed I saw tho

 

Very accurate providing you hold the speed for a while.

They will always tell you a speed which is slightly higher than you are actually going though due to the way the innaccuracies work with them.

 

tel us mate..its all good as it was on a privtae strip

 

Well in that case this thread is gayer than inviting gracey and alex round to relentlessly take turns to bugger you all night.

 

It wasnt any headling record speed or anything as I was just testing the pick up in 5th and then holding it in gear.

 

Well still put some numbers to what you did get to and how it got there

 

168 at 7k in 5th before I lifted was holding 2.2 bar

 

Thats properly motoring for on a "private track" esecially if there are a few other people on it at the same time!

 

What are your gear ratios now? Different box etc havent you?

 

5th does feel noticeable taller as its not quite as happy to cruise at say 50/60 in 5th as it was before, if you know what i mean

 

on a long enough stretch it would have no probs hitting the limiter at 8k Im 100% sure of that after the way it got to 7k so quickly.

 

Euan,
The easy way to do it is to give me the ratio of your fifth gear, the tyre sizes you are running on the rear and then I can come up with a figure to compare with your road angel . Obviously it won't be exact, but it will give you something to look at .

 

Nice one euan

 

I haver the ratios somewhere Mike so will send you apm tonight after work

 

Whens it next out at brunters or similar?

 

when ever the daddy thrash is

 

Fantastic


When I was a kid I always thought that red cars were the quickest ones, but with sierras it seems its white ones

 

you free this wednesday?

 

That's 192mph if 168mph at 7k is accurate

 

How did you calculate that? He hasnt mentioned his 5th gear ratio yet

 

I'm guessing 168/7*8=192

But I don't think it works like that

 

course he has, he said that x rpm = y mph

 

168/7 = 24 mph per 1000rpm
24 * 8 = 192

 

168 / 7
multiply this by 8

 

Chip can you quantifie your comment regarding accuracys please just very curious to hear your veiw


Mike

 

true, providing the road angel is correct. (suppose its not gonna be a million miles out tho is it)

 

Nice!

Was that on the usual test track Euan?

I can rememebr on the Roadpilot in Davies car acceletating faster in 3rd gear than the GPS was reading, as in the GPS was playing catch up for a while.

 

Good going !

On the subject of top speeds aren't M3's supposed to be limited ? E46's that is ?

Saturday night we just popped to our local test track and whilst my mates now not so Slowline pulled past 180 the M3 was showing 166 mph !

Surely they should be limited to 155mph ?

Without doubt they won't of got there as quick as Euans must though

Whats the new gearbox like Euan ? is it dogleg ?

 

Picture yourself travelling in a straight line.

Put a dot where you are every second.

Add some innacuracy to move the dot in a random direction by a small margin.

If it goes straight forward or back, it comes out in the wash, it looks like one reading is quicker and the next is slower, but if the dot goes off the line you are travelling in (it will) then it will ALWAYS result in an average increase in distance travelled, therefore makingyour speed look higher than it is.

 

correct me if l am wrong though but as long as you have a sufficient Horizantal dilution of position and vertical dilution of position value then it should be pretty dam accurate should it not, l only know from parking boats with gps !


Mike

 

1st 3.38
2nd 2.20
3rd 1.40
4th 1.00
5th 0.81


those are the ratios of the new box.

Its runs a standard diff.

 

whats happening then Stav?

 

at a guess the daddy thrash?

 

Hi Euan the Road Angle updates its speed every 0.8 seconds.

Also at Woodbridge last year it was giving out the same speed reading as the Racelogic Driftbox within 1mph.

I use the Road Angle as my Speedo, the only problem is, if it drops down to 2 satalites (like up in the Highlands here) it tends to display randon numbers!

S.

 

Err, no! LOL Stav works for another mag so that's quite unlikely!

Euan, you have PM

 

cheers for the info Si

hows tricks??

 

reading you loud and clear Dave

 

i know,it was said in jest,hence the tears of laughter,
