anyone have this? just wondering what your thoughts are on this

 

Dude stop pissing everyone off, if you want to know your horsepower to go GM's website, not like you've done anthing to increase the power.

 

Yeah Amit you IDIOT quit pissing us off !!!


I think he wants it for corner / braking G's etc . Those things are ****ing cool !! I was just saying how ultra kewl it would be to duct tape them to our stomachs and run around really fast

 

^what he said. if i wanted to know my HP numbers then id just go and dyno for a fraction of the cost of a gtech.

settle down, slugger.

 

I have the g-tech pro. Not sure if its the same one because mines just the basic LED model, not the fancier one they came out with a couple years ago.

 

I have one of the Pro Competition as well as some thoughts.
What do you want to know?

 

i just wanna know how accurate it is.. and is it worth the $$$?

thanks!

 

Amit,
The main thing is that it gives very repeatable readings. From this you can use it as a tool to see if any changes you make to the car translate to actual improvements in ET/MPH... as long as you have a baseline and that is repeatable.
MPH is measured at the very end of the 1/4 or 1/8 so the reading should be a few MPH higher than at the track. The track only measures the last 60 feet.
It uses 3 accelerometers and has a self leveling feature (the first GTech only had 1 accelerometer and it was very critical that the unit was mounted very level).

A couple of things that you have to be careful of when using it on the street (use a quiet road out in the country):
1. The road must be flat/level throughout the 1/8 or 1/4 mile. This is difficult to see by eye. If in doubt, make the pass in both directions.
2. The rollout is very critical. The default setting is 12 inches. You can change this from 0 to 16 inches. I don't know what it is at the track. If you set it to 0, then you will have higher ET's and lower MPH because the unit starts timing the moment you start moving. If you set it to 16 inches, you will have lower ET's and Higher MPH since you end up with a running start at the line. The track uses between 6-12 inches depending on your front tire diameter but I haven't been able to figure out what rollout yet.

I took it to the track but only used it on one pass and the rollout was set at 10 inches and my readings were all slower than the track times. This means that the track has a higher rollout distance.

Since it was given to me, I think it is well worth the $. However, I would have purchased it anyway as it has many good features like 60', 330', 0-60 etc. It is a decent piece of hardware for measuring performance changes.

If you have any other questions, just let me know.

 

No, you would go to GM's web site for free, its got your HP numbers posted.

 

dude, are you on the rag or something?

last time i checked i wasnt aware that gm had the rwhp numbers posted?
