I hear the Gtech Pro can be inaccurate but consistent. Made me wonder if it could be used in place of a dyno. I understand this thing is not even clsoe to a dyno, but its just a thought . Also, doesnt have to be a gtech...could be that one by apexi or blitz too..

Thoughts?

 

Yea its pretty consistent, but you must do the runs in succession. Do 5 runs, take the top 3 and average them.

i would guess it would be a waste of your time, i deffinately wouldnt use to to try and tune something important, but liek i said i would guess its a waste

 

Gtech pro is not accurate, esp. with the horsepower function.
My R got an average of 140whp with Gtech pro (and I highly doubt it)

But the 1/4 mile function is pretty consistant. Although I think it is a bit underestimated, it serves as a good relative figure to compare mod.

In short, I will say Gtech pro is not accurate, but consistant to give a relative figure.

 

dude you really want a home Dyno click here, http://www.charm.net/~mchaney/homedyno/homedyno.htm

 

hmm wonder if it works?

 

Hmmm...I've seen that but not in person. My high school auto teacher almost ordered one.

seems to think it works.

 

GTech Pro meters are very accurate.. I have even brought mine to the dragstrip and it's never been more than .2 of a second off, and it's always consistent if you use it properly. As far as horsepower readings, it works fine, run, do your mods, run again.. Don't expect the numbers to match up to a Dynojet or Mustang dyno for christ sake..

 

yeah how is that apex rev/speed meter? is it any good? seems decent and apex is a respectable brand. thanks
