TOP SPEEDS?
Moderator: martauto
Havent had mine flat since the rebuild as the car is all over the road at speed. Need new track rod ends and bushes methinks.
Before the rebuild it stuggled badly after 130 but it definitely didnt have as much power as it does now.
I still reckon though it wont go over 135/140 tops though as the gearing is very low. It wont even hit 90 in 3rd.
My previous cars were like this:
Astra GSI - 1cm off the clock (this car pulled like a train in any gear)
Honda CRX - 147 (screaming like a bitch and felt like 400mph)
Corsa Sport 1.6 - 128 (took ages lol)

Indicated 135 mph- then I had to back off as I was in fear of loosing my licance
From what I have read on here I can't decide if the speedos are accurate or not, I suppose if I set 120mph on the OBC I will find out.

been in my car when it was owned by my mate who first got it and modded it up, went off the clock, was not a pleasant experience sitting in the back doing 140+ on the A64 on a Saturday afternoon and watching some plonker pull out from left to right hand lane in a Sierra a few hundred yards up the road! Brown marks for sure!

115 (real mph) in my old L-jet 320
130 (real mph) in my (rebuilt) 325i, 3.91 diff, felt like it was going to hit the limiter (that would be 135-ish) but ran into traffi ehh.. out of runway
160 (indicated) in an E36 M3 Evo
150 (indicated) in a Porker 911 (964 C2), damn thing felt like I was doing doing 100, it was only because I looked at the speedo I decided to back off (wasn't my car..)

Except mine which is underreading by the time it gets to 50mph and gets worse as I go faster.Karan wrote:144 on GPS>>>>>

Astondg - can't you take the clock out and move the needle round a little.
I know it will sit back down onto the rest peg but all movements have a min and max point.
I have heard of this before after someone painted their needle and did not put it back properly and got inaccurate mph readings.

But wouldn't that make it read wrong all the time? Mine overreads below 50mph, is spot on at 50mph, and underreads above 50mph. Would moving the needle help that?rowemeister wrote:Astondg - can't you take the clock out and move the needle round a little.

Your problem is probably due to larger tires/wheels.astondg wrote: But wouldn't that make it read wrong all the time? Mine overreads below 50mph, is spot on at 50mph, and underreads above 50mph. Would moving the needle help that?
This would cause an error which is percentual to the speed, which is why it starts overreading (because the speedo is offset about 5mph from the factory) and ends up underreading (at 50mph the error cancels out the factory offset).
If you move the park position of the needle you'll have same effect, but on a different speed.
No real fix except fitting the right tire size or recalibrating the speedo (probably not easy without the right tools).

Ok thanks. That makes sense. I didn't think my wheels were that big though, 205/50/16 should be just a fraction taller than the 205/55/15 that came on my car. Although I think that the 15s were a dealer fit option and my car actually came with 195/65/14 or something.rickk wrote:Your problem is probably due to larger tires/wheels.

Anyway, sorry to take this off topic. Thanks for everyones help but there'll be no more of that from me
On topic: I just set a new top speed record! 30mph down this longish hill on the way home and I was only about 1/3 maximum rpm in top gear so theres still more in it! On my mountain bike of course. Even then it's a bit slow, there aren't any big hills around.
