NEW 5.7 Hemi Turbo Cherokee 1/4 mile video

Some new video fun for you, this is an in cabin video of my Turbocharged Grand Cherokee making a 1/4 mile pass. Pay attention to the upper left hand corner, and next to the white lit gauge, you will see a green light illuminate indicating boost as the water/meth spray has activated at 1/3rd lb psi.

Next to this light is the AFR gauge, while the video is not super clear, you can make out the numbers and you will see the AFR go from 14.8 to around 12.8 when the green light comes on as I have it stalled on the converter around 4 psi of boost. Then when it launches, you will see the AFR drop to a low 11 and then around 10.5 AFR through the run as the boost goes to 7-8 psi.

When I let off, you will quickly see the AFR return back to a 14.7 AFR. The iEMS3 is controlling the fuel injectors, timing retard, boost control, and progressive water/meth injection all with a single electronic device. The factory ECU file is completely stock as is the engine.

Turn UP the volume! And go full screen mode!





Please note that this video was shot on an abandoned, limited access roadway with no traffic, only one way in or out, water on both sides, and no possibility of any pedestrians!

System works well! Now you can beat stock SRT8's.

Re: NEW 5.7 Hemi Turbo Cherokee 1/4 mile video

Tim, very nice... What was used to meassure the ET? Dashhawk?
Are you planing to take it to the track?
If I still had my old 5.7L I wiuld definitely be considering this turbo set up.
Heck, I'm considering it for the SRT8, I just can't afford it right now .
Keep up the good work, and good luck, hopefully some of this guys start to add some turbos to their 5.7s.

In that run it was measured with a dashhawk. The log file is dead nuts on, there are no spikes in either the rpm or MPH. At the track I have run a 13.39@104.6, the difference is with the dashhawk I can make a run before the vehicle is heat soaked, at the track no matter what I do, by the time you get up to the line and staged, it is heat soaked. If I make back to back passes on the dashhawk, the second run is almost equal to my track times after it heats up.

Best 0-60 mph was 4.18 seconds with me and Escape in the vehicle.

It makes a lot of sense Tim. Thanks.
My times at the track with the dashahwk were just a couple of tenths off from the timeslip. Not that that happens to everyone, yours could be dead on as you explained.

Very nice man. I think your kits are a great deal.

My Autometer D-PIC is cosistant with itself but not accurate to track times.

It would make a killer set up on an SRT-8 clone (hint, hint)!
