lo all

Just been looking around and knowticed some people have hit over 130mph in 4th gear :wow:

Now this i find odd, my B16B is on its std ecu - and still has the std 180kph/112mph speedlimiter as normal. However I find i can hit the revlimit in 4th before i hit the speedlimiter of 180/112, thus i have to change to 5th for a few 100 rpm before i hit the speedlimiter.

Now i can understand that speedo's and tachos can be out, however im sure the revlimiter and speedlimiter are set in stone at 8.4K and 180/112.

Is this right?

Ive no reason to belive my g/box has had anything special done to it, and its defo an S4C LSD box, only thing i know has been done to it is its been cleaned up and the LSD print has come off. I bought my engine/box etc of a guy who bought a front clip fof an EK9 from japan - and i know he didnt do naything to the gbox.

Any ideas? or is this normal?

same here i hit the limiter in 4th before i hit the speed limited in 5th. oh and changing from 4th to 5th at excessive speeds the gear bag crunches, doubt this is normal?! like im talking 115mp - 120mph it crunches

no thats not normal, check out this thread,

and you can hit 125mph in 4th if your shifting at 9000rpm

hey blinx according to this calculator,fifth gear does 165 mph surely this is wrong,is this just a theoretical top speed? as in real use i doubt that an ek9 could reach this speed,what do you make of this?

it is correct, the calculator only calculates gearing not the BHP to get you to those speeds and the weight of the car, its not saying that an ek9 can go 165, its saying that an ek9 tranny will take the car to 165 assuming the car has enough power :nice:
