I'm with you. I'm generally happy with the turbo system. When the boost comes online the jeep is a rocketship. I cant' fathom the feel of being on boost throughout the entire functional driving range, if boost is achieved at or below 2000rpm. I would/will be first in line to try out the new precision turbo if it is either direct replacement or minimal effort to swap.Quote:

I was told that this was with 2 adults in the Jeep and at 83*F

Some excaples under/around $40k:
Hyundai Genesis 3.8 R-spec coupe, $34k, 348hp, 5.0 seconds
Chrysler 300 SRT8, $5k 470hp, 4.3 seconds
Mitsubishi Lancer Evoluation GSR, $42k, 4.8 seconds
Chevy Camaro SS1LE 43k 4.3 seconds
Ford Mustang GT PRemium $40k 4.3 seconds
Subaru impresa WRX Special Edition, $30k, 4.7 seconds
The Precision Turbo option has delivered excellent performance for us so far. This is a much more aggressive setup. Fuel economy is down some but maybe that's because I can't keep my foot out of it. It truly is sports car fast. I am trying to get the time to make some video of the setup so people can experience what the system looks like piece by piece and what it sounds like. Prodigy Performance has delivers best in class performance. Videos soon to come. Do some research on Precision Turbo. All of the big names in High HP run Precision units. Garrett in my opinion is considered a reliable workhorse where as Precision is considered a more Extreme performance Version. IMO
We will also be testing a performance torque converter with a higher stall speed. I am expecting this to lower 0-60 times even further. (sub 4s although traction will now be a big factor) We also expect this to bring the Prodigy Jeep into the 12 second quarter mile times! (currently 13.3) I am being very careful to remain consistent on testing numbers and not to ever skew the results as to never deceive the public. If you have any questions let me know. As for now the schedule goes as follows.
1. Video 0-60
2. Video product walk through
3. Video sound clips
4. Dyno with Precision turbo at stage 2 boost level set by wastegate spring 0.5bar (no boost controller)
5. Install torque converter
6. Video track runs and achieve first World's First Wrangler in the 12s
7. Install boost controller, return to dyno and achieve World's first Wrangler over 400RWHP ++++
Piece of cake. As long as you have a Prodigy Turbo kit LOL
This just keeps getting more interesting/exciting!
No love for us with manual transmission Jeeps? Is there any possibility for improvements, such as:Quote:

* Mods to the manual trans to make it shift more quickly? I think it takes me almost a full second to shift from 1st to 2nd gear because of the long throw and how long it takes for the 2nd gear synchros to do their job. Maybe I just need to be more forceful to make the shift happen faster?
Do you expect to achieve this reliably on stock engine internals, or is this where the forged pistons become necessary/recommended?Quote:

Seriously though - I'm highly considering picking one up as MPG doesn't concern me (though mine actually improved with the turbo) and drive-ability is everything. Keep us updated.
pickles jeep is a 2 door soft top right? stock wheels? Pretty much every other jeep in america is heavier than that rig. I think its unrealistic to say that a prodigy turbo promises a 4.24 0-60.
Snarf's turbo on the other hand, lifted with 37s would be more of a barometer for the rest of us. Snarf hook up your unit and see if you get what pickles got.
Because of how much variation there is in mods, tire size, 2 vs 4 doors, etc, no one can promise any specific acceleration performance numbers for any performance mod. Prodigy is not promising YOUR jeep will do 0-60 in 4.24s. What Prodigy is doing, though, is testing with a stock 2-door Wrangler, which is a solid baseline configuration of the vehicle. This allows you to compare to reported 0-60 and 1/4 mile results from car websites/magazines (which are also based on stock vehicles).
Stock 2-door Wranglers are reported to do 0-60 in the 6.8-7.2s range, and 1/4 mile around 15.5-15.8s.
I did not get this 4.24s 0-60. This is Prodigy's test Jeep with a new/different turbo than what Snarf and I have. It's also an automatic transmission, which is faster than the manual transmission (both Snarf and I have manuals).Quote:
