Normally if you buy a proper 240kph/300/320 speedo (not just changing the face over to the one with more numbers on it) then you don't need to calibrate it. Just plug and play.

It may be out by 5-10% depending on ur car transmission, diff ratio, gear ratios, etc.. but I personally won't be too bothered about it. I just know with my nismo 300kph one, I'm only doing 91km/h actual speed when i'm doing 100km/h according to the speedo. Can be tested on a dyno or any of the roadside speed check displays.

all you dudes out there who have over 200kph speedos, where did you get them recalibrated? can any1 recommend a place?

p.s its along time since i've posted on SDU!

:wub:

Depends what type it is.

If it is a mechanical type you are pretty much restriced to changing the drive gear for the speedo in the gearbox.

If it is electronic you can have it recalibrated any way you like.

haha wel jsut have to guess, if you dont want to spend too much money

remember 60 miles per hour = 100 kilometers per hour

ahhah it doesnt read correctly in either units :) probably because US spec is different, since its ment for USA instrument, oh well, i'll just have to hook up my HKS turbo timer to read speed.

I have the same problem with my Tomei 310 km/h speedo, reading progressively out. I didn't have the money to recalibrate it (Tisco told me it would be $250 just for them to hook up their equipment), I borrowed someone's GPS and made note of the speeds that way :)

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
