Just wondering if anyone on here with 18" wheels with 35 profile tyres has ever hit the rev limiter in 5th, ive done this and my speedo said 155mph witch i cant help thinking is slightly wrong. Anyone now what speed i was actualy doing, it was on an airfield of corse Also is there anything i can buy that will tell me my speed using the same principal as sat nav, i dont really wont to fork out for that as i have an AA road map

My redtop astra wasn't far off hitting the limiter in 5th, 500rpm or so away. Was showing an indicated 149mph

That was with 17's and 40 profile tyres

I have no idea about the accurate top speed of a 2wd cosworth but you may want to keep these 2 pictures in mind next time you bounce it off the limiter




Thats what happened in my mates stage 3 saff when approaching a indicated 170mph, speedo is porbably miles out but revs weren't and it was right in the redline.

Might be worth getting the fuelling checked for sure if your into your top speed runs

Hi m8

The last time I went to the Nurgburgring, on the Autobahn in Germany with the old esc-co cossie rims that I used to run on my 2WD which gave a slightly undersized tyre on 215-40-16 tyres, I managed to hit indicated 169mph (dont put too much stock in actual speed though!)

At this point, I felt what was either the limiter, or more likely a mis-fire and backed the f**k off!

your speedo is out cos your on 18s but if you were on the limiter at say 7200 you were going 180 ish unless it was just a miss fire as for the pics shown thqats just to much boost/ignition or lack of fuel its detenation anyway

Yes have a Data Logged 8300rpm in 5th thats 210.2mph in my Saff.
Have lengthen the gearing & would have to hit 217.4mph to hit it now & thats very unlikely, but we are going to try .

whats the standard limiter on a 2wd? 6800?

ive done the limiter in 5th in mine, but thats just under 140mph

look on bernie's website www.gearboxman.co.uk there's a gearspeed calculator

When i had my 3DR i hit an indicated 168mph on the GPS, That was with 35 profile 18's on aswell.

The speedo was showing 170mph when the GPS was showing 155ish.....so that is how much the speedo was out with the big wheels on and dont forget it was running 20 year old Speedo technology aswell

No worries there mate been mapped by amhed and harvey , thanks every one for the replies, anyone know if you can get gps that just tells your speed had a search on the net but no joy

rapidcossie

As said above go for a snooper or road angel shows speed and when to hit the brakes

do the G-Tech meters monitor speed ?

I nearly did but stoped, as hitting limiter in 5th cant be good for the engine!

cossie350

Nice one didnt know snoopers told you the speed as well, i shall order one now

cossie350

Ive only done it the once and it was a bit of a mistake, gotta bit carried away smokin some jap crap so it was for a good cause

RichardC

I think Im right in saying that the GPS info on snoopers isnt quite in realtime, theres upto a seconds delay

Ginge !

but launching it with 7k side step launches are mugh nicer i bet


ive had a nova xe goe off the clock and then hit the 0 pin stop and was still acclerating but that was only at 6600rpm(ish , at that speed i was mostlyu looking forward AND looking behind me so the rev counter was a brief look )


the fastest ive had the cossie is 145 on my old road angel,,,,,,,,,,, at 130 plus they done feel that nice and 145 was the point when i ran out of balls tbh



ive hit the rev limiter in a 350z in 5th gear but that dont count as there 6 speed i guess but there rev limit nose dives in 5th gear and thats around the 150 mark,,,,,,,,,,, SERIOUS brown trouser moment i can tell ya

Dumped from this BB used to hit limiter in fifth two or three times each time the car came out of the garage.

RW

Ginge !

Ginge! You told me your were borrowing my XE nova to visit your nan in hospital

I might try matching that record at central day depending on how the RS comes out

Steve200+

I've allegedly done this, and if memory serves on the rev limit (7500), it worked out to 171.6mph with clear condition, no wind affecting, actual speedo was bending the needle.

On my private runway.

i was at 6.800rpm on 17" wheels and ther was no limmiter and my speedo showed 170 mph i just held it ther same engine still going strong

cossie4is dad

Mine has been timed at 162.2mph at about 6750rpm thats on 205/40/17s

Have hit the limiter a couple of times, mine is set at 7000rpm.
