I got curious and stopped at a local landscape supply to weigh my Jeep on their scale:



3960 lbs

This is with a full tank of gas (just filled up 2 miles away) and whatever random stuff I typically have in the Jeep at all times (nothing really heavy: hat, sunglasses, tow strap, gloves, soft top boot, etc).

According to this document from Jeep, the curb weight of the base model 2-door is 3849 lbs: https://www.jeep.com/assets/pdf/wrangler_specs.pdf

Mine is the base model + A/C. I haven't been able to find anything about how much weight is added by A/C.
I also can't find any details on how Jeep measures curb weight. Some manufacturers measure with a full tank of gas, 3/4 full or 1/2 full.
So since I didn't weigh it before installing the turbo, there's no way to determine how much weight is added by the stage 2 turbo kit.

But now that I do know my actual weight, and Prodigy has released some dyno charts, I have all the info I need to simulate how quickly my Jeep should be able to accelerate.

Assumptions for the simulation: Total vehicle weight is 3960 lbs + 140 lbs (my weight) = 4100 lbs. Launch at 2500 RPM (seems reasonable to avoid roasting the clutch). Each gear change completed in 0.6s (the best I've seen in a data log).

Max acceleration: ~1.1 G around 27 mph in 1st gear

0-60 mph: 4.85s
1/8 mile: 8.63s @ 88.28 mph
1/4 mile: 13.22s @ 106.56 mph


NOTE: The 1/8 mile trap speed of 88 mph is not only enough to travel through time, but is also about the same as the stock 1/4 mile trap speed, which takes about 15.5-16.0s, depending on which car website's results you trust.

Now if you're willing to roast the clutch a bit (or install a high performance clutch) for some 4000 RPM launches...

0-60 mph: 3.99s
1/8 mile: 7.94s @ 88.89 mph
1/4 mile: 12.51s @ 106.87 mph


And how about some highway/freeway "passing power" examples...

60-80 mph, 6th gear: 26.90s
60-80 mph, 5th gear: 13.81s
60-80 mph, 4th gear: 5.66s
60-80 mph, 3rd gear: 2.51s

40-60 mph, 6th gear: 15.64s
40-60 mph, 5th gear: 12.00s
40-60 mph, 4th gear: 8.23s
40-60 mph, 3rd gear: 3.60s
40-60 mph, 2nd gear: 1.56s


Obviously, with the turbo's big gains in the mid-to-upper RPM range, downshifting is your friend here. It's interesting that 5th and 6th gear are faster from 40-60 than 60-80, even though they are at lower RPMs in the 40-60 acceleration, with less torque available. That's a good example of how much more power is lost to aerodynamic drag above 60 mph.

I think I'll try data logging some 40-60 and 60-80 accelerations in different gears to compare real world results to the simulated results and get an idea of how good my predictions are. I have no way of reliably simulating turbo spool/lag when initially going full throttle, so real-world results should be slower if I start my acceleration right at 40/60 mph. If I start the acceleration at a lower speed, the time it takes for me to pass through 40-60 and 60-80 should be close to the predicted results.
