WR1 60MPH Challenge
WR1's only for this one guy and girls.
I need your help again!... I need you when your out and about in your car to check how many revs your pulling at 60MPH... MUST BE BANG ON 60MPH FOR THIS TO WORK IN 6TH GEAR... I need as much feedback as poss on this please as it may help you WR1 owners in the future. Thanks again...  Last edited by Gazman2054 on Mon Apr 17, 2006 1:24 pm, edited 1 time in total.
4th, 5th ?  don't u mean 2nd/ 3rd !?  he did say 60 right, or 160 ?!
I didn't think they'd do 60 mph in 2nd due to the gearing?
Too petty to be a traffic warden...
Been talking to Mick C at Donno today, checked ours on the way back, 60 MPH in 6th = 2400 RPM
Was this 60 mph on the speedo or a 60 mph reading on a GPS system?
Too petty to be a traffic warden...
still want to know what gear, had 60 at a few times today, but still do not know what he requires
By the speedo
Check it out.. Just input Wheel/ Tyre size 18" 225/40 and diff ratio 3.9 I believe and scroll down to 6 speed UK box.

hmmm not sure, maybe, will try tomorrow and let u know. i can get about 8k revs so it might be possible...
7500=60 mph in second.
Right Guys. The reason Garry has posted this request is. Due to an accident the rear diff had to be changed on his WR1, ever since this change his car when running in manual drives like an old land rover the steering wheel feels lumpy and only wants to go in a stright line and you can sense the diff winding up and then with a loud crack it unwinds. In auto it still makes this noise. The dealer that fitted his new diff [who are now out of business] fitted a 3.5 to 1 diff as stated to them by Subaru. So Garry, quit rightly suspects the diff is the wrong one, so he posted a request for some help. I invited him over to my place so we could check out his diff. By jacking up the car and counting the number of prop shaft turns to one rotation of the road wheel, we found that sure enough he has a 3.5 diff fitted, before he came over I tried my car which appears to drive like his did before the change and to my disgust my car has a 3.5 diff as well, so we run both cars along the same stretch of road at 60 mph in 6th gear and checked the rev counter, this can only be taken as a rough check as tyre wear and pressures could influence this check, both cars did the same between 2300 and 2400 rpm. Now I also checked on my car the diff casing, this has a two letter code in white paint on the top, this can only be seen with a good light and a mirror, my car has the code HN but Garrys car has no code at all, my code has to be checked out yet through Subaru. What we are getting at here is we ALL paid for 3.9 Suretec diff's to be fitted. Do you all think we have them fitted with this evidence, I don't. This problem could happen to anyone of us if the diff requires a change. This is why Garry has brought this to our attention. Please believe me this driving experience in Garrys car was awful. Thanks to Paul N for checking his car yesterday, your car needs jacking up and checking as well Paul if you want to, PM me on this and that goes for any WR1 owner.
Tried this web page doesn't seem to work
Mick C,
The 'Suretrac' (gearless) diff is the front one......Not the rear, which is a full 'Mechanical' diff - Hence the 'Rear Diff Temp' light on the dash! Lee. Sold out and bought an EVO......then sold it because it was rubbish!
Sorry people.
Should be 60MPH in 6TH gear by the speedo... Our brochure say the WR1 has a 3.900 final gear ratio which seems to be incorrect. Mine and Mick C's are both fitted with the 3.545 Brochure also say it should be fitted with front and rear suretrack differentials...
yep indeed sounds right, 60 mph in 2nd is achievable. i checked 
60mph,
6th gear= 2400rpm, 5th gear= 3000rpm, 4th gear= 4300rpm. did not bother with 3rd and 2nd but looks like dan has done a 2nd gear trial
FASTER,FASTER  Crash bang wollop!!
Thanks for that Lee. Is the front diff a 3.9 to 1 and the rear a 3.9 or a 3.5 as the engine revs would indicate the 3.5 is fitted.
Not 100% sure of myself here so excuse any errors.
Aren't there drop gears between the engine and rear diff, presumably to do with the centre diff? Some spec cars have 1:1 drop gears (JDM if I recall rightly) others have 1.1:1 drop gears (UK cars?). So if you want to compare like to like it's no good counting prop rotations and driveshaft rotations on the front and backbecause the prop is after the drop gear. You need to compare engine rotations with drive shaft rotations front and back back. Sanity check, 3.54 x 1.1 is 3.9 near as damn it, so yeas sounds feasible. So a 3.9 front diff would correctly match a 1.1 drop gear and 3.54 rear diff. Final drive ratio would be 3.9 front and rear.
Ta for that matey.
I was told about the drop gearing but was'nt sure about it. Problem is what the bugger is wrong with my car??? Sounds like the drop gear could be shot or the center diff could be buggered too...
2400rpm in 6th 60mph
according to psi 3 monitor aswell 2007 BMW M5
2004 Petter Solberg STi
Will try again. http://www.bob.szhosting.net/Doc's/ratios.xls does not underline the whole URL works with copy/paste 2400rpm= 60.8 according to the chart.
