i have an 87 GTA with a 140 mph electronic gauge cluster. i want to get a speedo that goes up to 200 or more 300 would be great. i dont care if it is stock looking or fitting into the old speedo spot i just dont know where to get anything like this. i iwll make it fit in my car if i can but i need something to work with. someone let me know

 

You could easily change the existing speedo to a higher mph by using an ERA from www.atrol.com I bought one for my 87 TransAm because I changed the gears in the rear end from a 2.73 to a 3.73. But you could buy one of these and change the pulse ratio to the speedo so that the speedo will read slow, then you can renumber the speedo with decals yourself, or send it to a guage rstoration/speedo shop (find them on lycos) and they will do it for you.

 

try autometer, I think they have some 200 mph ones.

 

i know they make it in the phantom series, but only for mechanical, i think 160mph is as high as they go for the electric ones.

 

i know they make a 300 mph electronic speedo for camaro's and monte carlos but not for trans am's i dont think. i see it in my hot rodders mag. it would be cool if i could get a stock looking one. i will check out your sugestions and let you guys know. also does anyone have any interest in a tremec 6 speed i have for sale have flywheel back. works great. was looking for 1500 not including shipping only 30 k miles on it

 

Probably not a bad buy on the Tremec

300MPH, , are you runnin this thing on the salt flats or what (seriously)?

 

hahah i am not running on salt flats i dont need a 300 mph speedo but i want one that does atleast 255 since that is when my fuel pump will shut off. some day i will get my car that fast with the right engine and low rear end gears. i am sure i can do it but i want a speedo that can handle it also. i iwll be like red lineing the car at 10000 rpms or something i am sure when i do it but i am going to a build an engine that can handle it. so anyone let me know what you come up with and also emial me at polygaryd@yahoo.com if you want that 6 speed. it is clean and in great working order i will money back gaurentee it

 

no offense but if ur doing 255 mph I would not suggest looking at the speed-o for any reason.. lol

and i know this thread is probly dead but i was just browsing and i found it

 

He lives in MA, we dont have salt flats, we do have litter and homless ppl.

 

i want one that does atleast 255 since that is when my fuel pump will shut off....

lmao, are you seriously

Ultra-Lite 5" electrical gauge
Speedometer, 200-MPH, In-Dash Mount
105-4490

Ultra-Lite 3 3/8" electrical gauge
Speedometer, 200-MPH, In-Dash Mount
105-4486

This programmable speedos feature ''push-button calibration'' that can be easily set while driving. This makes changing gear ratio or tire size easier than ever. The LCD odometer is highly visible and retains the actual mileage after recalibration or in the event 12-volt power is removed, also includes a resettable trip odometer. Will work with late-model transmissions that have an electronic (500 to 400,000 pulse/mile sender) output. Requires sender 105-5291 or 105-5292, if using an early model (cable driven speedo style) transmission.

 

lol that's what made me laugh (and cry) the most. the liters/hr your fuel pump supplies doesn't equal the miles/hr you can drive with it! lol. that's too funny....

 

PROM is probably programmed to cut fuel at that speed...

 

exactly! prom cuts off fuel at 255 has nothing to do with how much fuel it flows. and hey it may be an unattainable goal but at least i have one.. what r u doing with your time besides trying to type correct english grammer "are you seriously". haha also i am not sure if if any dynos will go that fast but you may not need roads to test the top speed and have it be that fast. the rest of you thanx for the tips on speedos and where to buy them.

 

Actually yes, you do, unless you have a windtunnel.

 

I can't get over the 664 days between the last couple posts!!! And responding as if only a second went by.

Amazing how time flies.

 

 

if you go 255 you are going to have a camaro that does cart wheels....lol there was a EXTREAMLY rare 160MPH dual pointer that was in 82 cross fire indy 500 pace cars and not all of them had it take a look........... but that original idea of re calbing your speedo and getting a new face plate will work good

 

Now that is AWSOME looking. I want one......But dont even need to know the price to know I cant afford it LMAO

 

or you could get a digital one

 

I'm gonna go with the guy that thinks its funny that were discussing a 2 year old post. :

 

cart wheels i think not.. and no you dont need a wind tunnel, like i said a dyno can do it in place i am sure.. anyway i have found some digital ones that go to 300 mph for the camaro and none for trans am but i still havent found any electric ones that go above 200 mph.. also it was a long time before i responded but that is because i came across this post while searching for another one i had listed for parts for sale and thought that one of the users is a complete tool to everyone and he should shut his mouth unless he is being helpful which he hasnt responded here so maybe he got the hint.

 

I think he means to find out the top speed the car can reach on the road you would need a windtunnel because there would be no wind resistance on a car on a dyno so you may be geared to go that fast but never really be able to hit it on the road.

 

why would you program the fuel cut at 255 does the car really go that fast and if so why limit it to 255 if it has the power and ability to go that fast why not just disable the fuel cut also what ecm are you using that has fuel cutoff in it

 

You can get a dakota digital dash or one from Cyberdyne tech. I understand about the fuel being cut off at 255. I don't know how you are planning on over-riding that in the ECM though. You will have other issues long before you ever think about getting a Camaro to over 200 mph though.

You could get a Dakota Digital or Cyberdyne digital dash. You might not ever see over the 200mph though.

 

I was planning on changing the engine to an lsx block with massive power, a t56 with .50 6th gear and a mid 3's ratio rear axle. All bought and paid for and went into a 4th gen instead. It was supposed to do over 200, I didn't need a 300mph speedo but one that goes over 200 to see top speed. I was also thinking of trying to put a low 3's or high 2's ratio rear axle and seeing how fast it would go in general pushing the limits of the 255mph cutoff but then realized that with a new ecu to drive the lsx block there may not be a speed limiter so.... It was just a ridiculous thing I wanted to try just to say I did it or my car could go that fast even for a second.

 

oh btw I came across this wicked old thread searching for another one of mine in the classifieds so I thought I'd post to it.

 

Zombie thread!!!!!!!

 

Hrrmmmm.... mine only goes to 85 and I'm happy with that! Hahaha

 

I still have my Series 2 Dakota Digital Dash for sale for $200 if anyone is still interested.. I took it out about 3 months ago to install the newest Dakota Dash after I returned back from Afghanistan.

This digital dash works 100% and goes to 255 mph.. I have enclosed another picture of what it look like when installed into the car. It will be shipped in a protective pelican case because of the electronics.
