I find many of these times posted hard to believe. I used to have a heavily modded 300ZX TT and ran against many modded RX-7's. The cars were quick, but not that quick. I dont trust these G TECH guages. Take it to a drag strip and do some runs, then compare to the G TECH and see how accurate it really is or isnt. I think you are pipe dreaming if you think you are turning out those times and MPH.

RSR,
I believe those times and speeds are possible with the mods you mention.

Frankly I don't really care about drag strip measurements in and of themselves. It is only a tool to measure performance mods and the impact of atmnosphere on the performance.

So, I am not "pipe dreaming" at all.

RSR, how much hp does your g-tech tell you that you have?

I need to get the weight dialed in a bit better, I listed as 3350 with me in the car, but I have GT3 seats and basically about 15 lb exhause rather than the OEM 60 pounds. If anything this should be more like 3440 or 3450 now that I have done the proper math.

I think I read 408 to the wheels, but this was using too low of a weight, so maybe 420 or so corrected.

The G-tech meter is actually precise enough to allow the user to set the starting rollout between 0-16 inches. The unit's default is 12 inches. Times can be manipulated at the track by staging with different rollouts. If you perform a track time to G-tech time test the rollouts must match to offer a correct comparison. Here's a link to a scanned page from the G-tech Pro Competition meter manual. It's quite interesting regarding the rollout.

Page from G-tech manual

I purchased my meter from Lopers performance. Many of the guys there are seasoned track boys, and have taken their G-tech meters down the strip with setting their rollout similar to how they staged. The times come out pretty darn close. Many others have done the same to confirm accuracy as well.

Notable variance between track time and G-tech time could be achieved by staging differently than how the G-tech meter is set for rollout or by not calibrating the unit. This is when information becomes confused. As expected there will always be those individuals which use the meters incorrectly and subsequently offer erroneous information about the unit.

My meter is calibrated correctly. The meter is set to the unit's default 12 inch rollout. They really do work well.

With my mods I'm at 385rwhp with the g-tech, which seems right to me. Is your ecu set up that aggresive?

Dumb question of the thread:

How does it know what RPMs you're engine is at?

Scott,
It reads the electrical "hum" in your lighter caused by the cars ignition system. You calibrate the unit at two points say 2000 and 4000 rpm then it can read the rest.
