I just ordered the G-Tech Pro RR Meter yesterday, total price delivered was $255. And just my luck I was looking at a place that I had priced them yesterday and they put them on sale today for $169.95 delivered. I had done some research on these units yesterday and from what I had read they are very accurate, but you need to know your car's exact weight. Lucky for me I live in farm land USA so I had a choice of four different places to stop and weigh my car yesterday on my way home from work. The car's weight without me in it was 3,070 pounds, has anybody else weighed their car if so what did it weigh?

 

Don't feel too bad for the purchase price, I almost paid 3 for mine delivered. I have had great luck with mine except for it measuring my HP and TQ. I have done all the configs that the book directs, setting up the pitch factor and everything, but have not had accurate HP/TQ numbers. Its on the money with G's, and on the money for times at the race track. I have entered my car at 3,000 just to be a round safe number, and have not had a chance to put it on an actual scale yet, but sounds like I am at least close with your weigh in. Let me know if you have any luck with your GTech, and what your pitch factor and all are set at? I would appreciate it.

Thank you,

 

Just out of curiosity, were the scales certified?
What were the measurement increments 1/5/10 lbs etc?
If you can get it weighed for free, you may want to get it checked at all 4 places.
How much gas was in the tank?

 

Here is a site to help trouble shoot any problems you may be having: http://www.gtechprosupport.com/support/FAQComp.htm
I wanted to get one of these because I've been asked several times what the 0 to 60 time is with the Renntech kit and what it will do in the 1/4. I live in the boonies with no 1/4 mile tracks close by, so I hope this little gadget will help me to find out. There's a guy that has a stock SRT 6 that just lives about 5 miles from me so I'll get with him and we'll do some comparisons between the two cars.

 

Thank you, I appreciate the link. Let us know, as we are all curious due to the prices of most and any upgrades what kind of gains we will see. Now if only I had an SRT. My "local" 1/4 mile is almost 150 miles away, but I wanted to correctly input the data so my gtech was accurate. You need a 1/4 mile slip to accurately figure your pitch factor, if memory serves.

 

Yes they were certified, measured in 1 pound increments and I had just a little over 1/2 tank of gas. The guy at the scales had to come out and look at the car, he had never seen a Crossfire.

 

From what I read in the link I posted, it's normal for the meter to show a lower H.P. & TQ numbers than you would see on a dyno. It's because you are actually cutting through the air with a lot of resistance and also your tire's are not on smooth drum roller's. And on the 1/4 mile slip, your time starts as soon as you move, were the meter doesn't start until you have moved 12".

 

That is correct with only two notes from me. Lol. You can set the gtech to have a "0" roll out, so it starts straight away as long as you launch hard enough to start the gauge, it tells you to only get part way through 1st and then get into second and use it for a full rpm spectrum so that you have a good band for the gauge to work with, and that way you aren't going excessive speeds to deal with a high number of resistances air, wind, etc. I can understand that the dyno gives better results but my hp/tq numbers are down at around 100 or so?

 

$169 for a Gtec no way, if your referring to those on ebay then all I can say is stay away from those. If you go to g-tecs web site they will go into more depth as to why you shouldn't purchase the ebay g-tecs.

As for being accurate, yes they are, more accurate than dynos.

 

The one I bought for $255 was off E-Bay, the guy is an AUTHORIZED DEALER with a 99.6 feed back rating and has a full warranty. The one that I was looking at this morning for $169 was not on E-Bay, for $50 I'll post the site for you, just kidding. But for any body wanting one of these babies for cheap, here you go.
[ EDIT ] removed link, not available from them anymore.

 

I weighed the car (6 spd) on a cert. scale before I started gutting it, to see how much weight I removed. The scales are +/- 40 lbs and the car had 1/2 tank (2,960 lbs).

Now the FUN STUFF. My car currently weighs (2,490) with roll cage and single F1 spec. driver seat !!! I'm still working on weight reduction and may go to Lexan instead of glass...

 

Mine is a bit of a porker at 3,084 lbs with a full tank, see thread here:

https://www.crossfireforum.org/forum...64&postcount=4

 

I'm planning on loosing 20 pounds of resonator in the soon future.

 

Why lexan? It scratches easily and is just a pain to deal with. And since your auto-x racing you will need a new windshield after every race. I could understand replacing the rear glass, maybe but not the front. Unless you can attach some sort of clear 3m film over it, it just aint worth the trouble.

 

Not true. At the drag strip your time does not start until you break the light. How quickly this occurs is dependent on how deep or shallow you stage.

 

I guess I stand corrected, I was going by what the site said that I posted on FAQ for the G TECH Meter. But I may have mis-read it too.

 

Man, this don't happen to me very often. I got LUCKY, for some reason the E-Bay store that I bought the GTECH from refunded my Pay Pal account, stating that they or I changed their mind. I think it may have had something to do with a new home e-mail address with our old home address. Anyway I went a head and ordered one from the site I had posted and saved myself a few $$.
Found out yesterday the company that had the GTECH for $169, is no longer available, sorry if my posting caused any problems.
