G-Tech Pro - Almost as good as the Turbonator!
#22
the older model is for sale all over Ebay, only about 30 bucks... for the extra 170 bucks, I wonder if the fancy display screen is really worth it... and then there's the G-tech RR (road racing) model... that's 300 bucks

This is a lesser known meter but works very well. I bought one a couple of years ago and am very happy with it. Dual accelerometers so it does not have to be leveled.

If you calibrate it correctly, and keep it from moving during your run it can be very accurate. Within 1/10 on your quarter mile times, but it will read a little high on the MPH (it measures instantaneous MPH....your mph at the track is an average over your last 66 feet of your run).

I bought one because i wanted to see what my car would do and when I start adding mods if they actually work or not. as for the horsepower, you actually have to make a horsepoewr run, you start off in first gradually shift into second at 3000-3500 rpms and floor it al the way through second and then shift into third and then it will give you the most accurate horsepower at the wheels with wind resistance(drag). my qiuckest times so far have been 5.05 0-60 and a 13.42 1/4 mile at 106. you calibrate your RPMS, enter vehicle weight and your set. I would recommend this to anyone who is thinking about having their car dynoed or doesent have a track around them (like me) i did buy the SS verson for 187.99 on ebay new with free shiping anymore questions PM me

I have both,gtech and Tazzo, the original gtech was fairly accurate if you set it up right, but it was cheaply built and I ended up resoldering connections twice, The Tazzo is a solid unit with a heavy duty mount, spot on accuracy when used at the strip.i.e. 60 ft 2.33, Tazzo 2.33, although final speed with Tazzo was .75mph faster. Great for practicing launch techniques without breaking the law...

You can't be serious... "If a cop catches you with one it can be considered racing" is something you accepted way too easily....
Hey I know, your car looks fast you MUST race it, lemme go ahead and impound that for ya.... might even save you an accident, who knows...
Maybe, maybe, maybe if you have a *****, you could be considered a rapist...
Maybe if you have a gun, you could be considered a murderer...

Some states have outlawed radar detectors, and 10,000s of tickets have been issued. As far as I know the Gtech,Tazzo are just measuring devices, like a speedometer. Mine goes to 200mph and no state has outlawed any of these devices.I would really like to know under which statute a LEO could write you a ticket, if all you you were guilty of ,was having such a device in your vehicle. Get real!

if ya want some good times use them while going up a bridge! youll have a 6 sec car!!!
but honestly im happy with mine it seems pritty realistic as long is you take the avg of say 6 runs and make sure you use it on FLAT FLAT FLAT!!!! ROADS ONLY

O YEA a way i came up with to cancle out any un seen curvature in the road is run the car in one direction, turn arround and run it back down the same strech of road and avg the 2 runs if they are different
#33
Mine was pretty accurate. Went 12.9@110mph on the g-tech and 12.78@109mph at the track w/ my old 99Z bolt-on A4 w/ F11cam. Best was 12.40@109.9mph at track on skinnes but had alot of KR and trans probs

Does it take wheel spin into consideration for calculating the HP/TQ #'s. Spinning will raise your ET, but should not affect your HP ratings...more HP more spinning. I think this looks like a fun new toy to mess around with. I will probably get one some time but I have some things I want to get for the car first.

I'd love to have one of these. I had the oldschool one. Honestly I'd love to see some sort of permanent looking install of these. That'd be reeealllly sweet. The 1/4 mile track is about 75-90 minutes from where I am, but I'd like to document header, stall, etc. changes ... heck ... weight reduction, free mods, different oil etc. It would be great!

You always dyno a car in it's 1:1 ratio gear, 4th for M6 cars, 3rd for Autos.
