Jeep Wrangler 91
4.6l twinturbo 10 psi
1/4 - haven't run
1/8 - 9.06 @ 83.6 mph

Haven't finished a run on max boost yet (the engine is build for a max boost at 17 psi) because of 2 breakdown on the powertrain at max boost.
A stronger powertrain is under construction.

60---1.8536
330--5.4892
1/8--8.5451
mph-80.23
1000-11.2077
mph-91.46
1/4--13.4737
mph-99.54

running with a ton of issues, including interference from ecm BC of no TCM, no O2, terrible tune running 10.3ish afrs, old all seasons, cracked header, low stall, and still getting used to the track.

hoping to go out on tues and make a cleaner run. really hoping to drop some time, but the DA really effects these boxes.

I'd like to run mine at irwindale or whatever strip is close to me. 4wd full time 5 speed is fun to drive. Wen my motors actually broken in & done ill do it.
I'd like to eventually run a 50 or 75 shot through it.

Driving my 4.7L '90 Cherokee with Borla header, I took my first long trip this month. I went from near Tucson to upper-mid Idaho and back, about 2400 miles. On the way back I decided to time 5 to 60 mph. Going up a freeway on-ramp pulling a 13' travel trailer (3000+ pounds) and camping gear, I clocked 20 seconds twice (on different ramps). The engine ran flawlessly all the way, averaging 14 mpg. That's the same as the previous 4L, but it was much faster up long, steep grades. Only trouble I had was back down in the Arizona desert: After stopping at a rest stop for 20-30 minutes it wouldn't start and keep running. Having experienced this before with the old engine I recognized vapor lock. It occurs when the gasoline gets so hot that the pressure drop at the pump inlet causes it to vaporize. Since the pump won't pump vapor very well, no start. I added 5 gal of cooler gas and got going. Researching, the best suggestion I saw was to add a quart or so of Diesel. Should work, but I haven't tried it yet. Next long trip, I'll carry a gallon of Diesel and see what happens...
