Is it a good a idea to keep speedometer stock after mods?

[Serbj]

I'm planning to install an independent digital speedometer to show a more accurate reading and the readings higher than the stock one's limit. It may be something like this:



or a head-up display:



While making it doesn't seem to be a problem, I'm wondering if going faster than 200 mph will damage the stock speedometer, since the speedometers on Galants appear to be Eddy current devices.

Any ideas?

you want to go faster than 200mph? Do you have ANY idea how fast that is?

you have to be joking..
First you say you want to keep your car street legal, because you are a lawful man.
Then you say you go trespassing on parking lots to practice auto-x, with which you use cheap tires (something you shouldn't skimp on)
Now you say you want to go over 200mph?

holy hell.. sorry but this is finally where I cave

PS: the stock speedometer only goes to 120mph

That's a typo, my brain was dead just now. It should be 120 mph

First the car is street legal.
Second I was not trespassing the parking lot. I'm a paid patron there and I know the owners.
And I check the tires on a regular basis. They are not even wearing out significantly faster than usual, as I don't do ass dragging at a high speed.

Thank you for your understanding.

[beam514]

okay, here's some questions:

Where are you going to be exceeding 120mph?
Why will you be exceeding 120mph?
Do you even have the supporting mods to surpass 120mph?
WILL you have the supporting mods to surpass 120mph?

Are you aware that the car is speed limited at around 120mph?

I've got a 4G63 DOHC head, ECU, turbo, and some other parts from an Evo 8, as well as aftermarket studs, gaskets, clutch, intercooler, EBC related stuff, etc. and currently they are resting in the garage. I'm waiting for a used transmission from Eclipse and some other minor parts which are going to arrive next week.

I came across this problem because I want to test the car a little bit on a track after the work is done. Certain the GPS is great way to read speed, but the GPS's screen display for speed is too small to read.


I hope I didn't insult you by this question. I don't mean to insult anyone with this question.

If beam514 hadn't mentioned it on post #2 you'd probably assume it's okay to post 200 m.ph. and carried on with this conversation.

I can spot ninja edits from far away and most of time it's for good intention but your post(s) has issues....

[Serbj]

What I mean is how to deal with reading a speed higher than the stock speedometer's limit. I don't mean to show off that I can go 120 or 200 or whatever a high speed. If it's for that kind of purposes, a forged (PS'ed) photo will do better.

I'm sorry if lacking of the concept of "200 mph" looks stupid or insulting.

Let me ask this. Where do you intend on getting above 120mph on the track? Certainly not in auto cross, in road racing you can get up to that type of speed on the main straight away, but why would it matter? All that matters with stuff like that is lap times. The factory speedo needle will go past the 120mph mark, I know from experience. You can get that thing all the way down into the odometer if your car can handle it. : )

Stop over thinking everything and put the car together and then address problems as they arise, if not, your gonna buy a bunch of stuff you dont need, be broke, disappointed and end up selling the car. It always happens. Just stick to the basics first.

if you are doing 200mph in your galant then the speedometer is the last thing you have to worry about.

Vouch for stewi, I've gone past the 120 mark couple of times. If anything, moving forwards with the topic. I personally like others recommend doing your engine and putting the major components together for your setup before worrying about minor concepts like speedometer as well. I do praise you for thinking big and sorta doing your research.

I would worry about the speedometer last....there are other more important things to worry about like making sure your car is safe to even go that fast to begin with. Cage, the right tires and things like that should be a priority. Im not even going to ask where you are going this fast because I am sure since you are a responsibly person you are doing this on a track where they have traps to tell you how fast you are going anyway

[Rabbi1991]

If you wana go this fast I recommend getting a roll cage, 8 point belt and don't have ANY passengers. Your talking about 200mph. McLaren F1 only had 240mph and it had that limit for a Long time. How will you get your galant to go that fast caus I want to do the same thing.

If i was wanting 200+ i would go with the bugatti, lol. At least if i were to wreck i would die happy. : )

i have heads up display speedo/tach (VSD CONCEPT). it was about $350 but i'm not sure they even make them anymore. here u go:



click the pic above for the video.

btw, it reads from 0-240mph and 0-9500rpm... so i guess if my car could reach 200mph+ it would let me know.

[bobmundo123]

that is gorgeous... much better looking then just the numbers.. very nice... im gonna be looking for that everywhere now
