Rpm vs mph - Willo - 16-11-2012 Hi is it me or does my diesel command hi revs vs road speed ie 3000 rpm @ 70 mph RE: Rpm vs mph - Mattcheese31 - 16-11-2012 nope that's right . . ![]() RE: Rpm vs mph - Anton - 16-11-2012 Thought it was 2900? RE: Rpm vs mph - Tom - 16-11-2012 Depends how much fuel your running aswell :p RE: Rpm vs mph - cwspellowe - 16-11-2012 Well.. no it doesn't Tom RE: Rpm vs mph - Anton - 16-11-2012 (16-11-2012, 09:46 AM)cwspellowe Wrote: Well.. no it doesn't Tom ![]() RE: Rpm vs mph - Tom - 16-11-2012 How so? I cant remember which way it was but in my old d tub if i turned the fuel up or down the revs would sit higher or lower at 70mph it was directly related to fueling ![]() RE: Rpm vs mph - cwspellowe - 16-11-2012 RPM and gearing are what affect road speed. 1000bhp or 100bhp, at the same engine speed and gear ratio you'll be going at the same road speed ![]() RE: Rpm vs mph - Anton - 16-11-2012 lol oh dear.......

Well played ![]() RE: Rpm vs mph - Willo - 16-11-2012 Oh right that's ok then thought it was a bit high RE: Rpm vs mph - Kwik - 16-11-2012 normal for a dturbo box hdi box is about 500rpm lower that's why myself and others have converted or are converting RE: Rpm vs mph - Dum-Dum - 16-11-2012 (16-11-2012, 09:21 AM)Willo Wrote: Hi is it me or does my diesel command hi revs vs road speed ieNah thats about right for a non turbo diesel. A DT or HDi gearbox will drop your revs lower. IIRC the DT is about 2700 at 70mph and the HDi is 2450rpm at 70mph. If you do want a DT box im putting a HDi box on mine in the next few weeks so you can have my old box for a tenner. (16-11-2012, 09:49 AM)Tom Wrote: How so?

The missus 206 hdi is crap for gearing, as soon as the power comes in it is time to change gear. Depends what you want really, iirc the dt box is better for day to day town driving and is much more fun and the hdi box is better for economy runs on the motorway RE: Rpm vs mph - Kwik - 16-11-2012 lol me being me is the hdi box for town and economy. dt box is too many gear changes needed for daily driving IMO RE: Rpm vs mph - strictly_perv - 16-11-2012 My 205's 2800 at 60 due to the small wheels.

I just find the power more accessible with the dt box, personal preference I suppose RE: Rpm vs mph - Kwik - 16-11-2012 exactly swings and roundabouts lol RE: Rpm vs mph - strictly_perv - 16-11-2012 For town driving would a shorter box be better as you can change earlier at say 1500rpm unlike a longer box where you'd have to change at higher revs to avoid it being too low at the next gear up? As said swings and round abouts. RE: Rpm vs mph - Dum-Dum - 16-11-2012 If you have the spread of power then the longer box makes for a more relaxing drive especially on the motorway but if your car has a very peaky power graph then you want the shorter box. also people with bugger all power might want the shorter box incase the car starts struggling on the motorway. RE: Rpm vs mph - Mattcheese31 - 16-11-2012 my 306 with 405 engine and box does 70mph at 3krpm fyi ![]() RE: Rpm vs mph - Daniel306 - 16-11-2012 Anyone know what RPM a Gti6 dose at 70, and what speed it dose at 5k in 6th RE: Rpm vs mph - Dum-Dum - 16-11-2012 5th at 7250 in a 6 is 133mph. Completely forgotten what it is in 6th. Got a feeling its 167mph though RE: Rpm vs mph - Daniel306 - 16-11-2012 I want to know what 5k would be RE: Rpm vs mph - Niall - 16-11-2012 at 70 in 6th, your at about 3.5k i think. i can confirm 5k in 6th is just approaching 140mph.....jesus i had to brake hard so i didnt hit the fence at the end of my garden!
