okay, I'll restate - king of reasonably priced NA V6

 

Who proved it? Did you own one? Have you tried it? I have a Gtech Pro and I compared it with my slip and found out that my Gtech Trap is .5 mph slower compare to my slip and ET is about .05-.03 faster which is pretty accurate I might say. That is less than .1 second accurate, so how accurate do you want? Do you want it to be .000001 accurate? These are over 5 runs I had that day..

 

Any honest gps provider will inform you that they are off by 5 feet or more (in some cases a lot more) - when you are tacking something as finite as 1/4 mile and you want an absolute; a gps based method is not the way to go about it. for loose representation its fine. I would never consider a gps based calculation as comparison to anything though.

I've researched bunches of gps tracking systems and utilized many of them in the industry I’m in... They aren’t even admissible in court to dispute moving violation because of the discrepancies.

 

Agreed

 

don't the IS350 & G35 (07+) both have 306hp, with similar torque? why am i reading that the IS350 is typically much quicker than the G? what am i missing here? without doing too much research i see the curb weights are similar, so the only thing i can think is that the IS350 has better/more gearing...

 

IS350 has better 1st and 2nd gear ratios and is capable of very low 60ft times stock. After 70-ish G outperforms it.....

 

What is this has to do with measuring acceleration? Gtech is an accelerometer and it is not a GPS. I dont care what GPS research you are talking about, I'm talking about real world experience base on my own time from the track and compared it to my Gtech #'s and it is damn close to the track # I had.

I've got nothing against accelerometers, just not a fan of the G-Tech.

 

Lol at that video.. first, Gtech dont read until you push the botton to start the stage, if it is starting while doing the burnout then he's an Idiot!! Second HP in Gtech is Net HP which add wind resistance, granted it is lower than the DYNO but every dyno also read different. Third I'm not the only one who actually did a test with Gtech at the Track, I believe Urban also did a test and within .1 of his track slip. 4th the guy has one run and maybe he hopped like crazy, vs my 6 runs and I have 5 very close # and 1 bad one but I miss a shift hopped like crazy. 5th you dont need to calibrate anything if you are just doing 1/4 mile, 1/8 mile or 0-60 runs... That guy probably set his roll out to 0 instead of leaving it to default... Video did his test and it was negative and I did my test and it was positive, video got 1 ran vs my 6 runs so who got a better test? I'm going back to the track in a month so I'll do more testing.. The video was also done in ETown which is the same track I go to.

Edit:
Here's Urban's post..

^^^ you go Gtech boy Its the next best thing to dyno racing.

 

hmm not sure how G35s are keeping up with IS350s..IS350s run mid 13s, last I checked most G35s can barely break into the 13s even with NA mods short of cams.....

From a roll maybe, from a dig I call BS w/o spraying or FI....

 

I had a G35 and it was as fast as the 335i with over 20k miles on it. IS350s aren't as fast as most 1/4 mile times show. Those things can take off and in a 1/4 mile time that is the single most important factor for a good ET.

Bone stock HR engine will give the IS nice whooping after 70mph.

 

Bench racing FTL. I can easily WALK an IS350 with my full bolt-on, tuned 06 G35 Coupe 6MT.

People over rate the IS350 because they don't understand its quick off the line and haven't had much experience against one.

The V36 G's can match the IS350's acceleration and the V35 is only a few bolt ons away from matching it.
