I used PerfExpert too. But second results wasn’t perfect. 19.62 @ 124km/hr for my 1/4
 
I unleashed the beast this morning going to work! Morning commuters were just passing me like normal.
1977 BJ40 - front and rear doors removed
B Engine - using Stanadyne fuel treatment. I do feel the difference when using fuel treatments. Not any faster but seems to run better.
4.11 gears
255/85 KM2s - 33's

I'm really curious to see what a stock HZJ77 runs. Anyone?
 
Pulled the 80 out of garage after shock install and went for a drive.

80 series BTJ80
Cummins 6BT p-pump with #10 fuel plate.
NV4500 trans
315/75 BFG KO2
4:10 axles with .9/1 high gear in transfer case.

It’s pretty dismal due to the NV4500 drives like a dump truck. I love it but you can’t get out of the first three gears fast enough to get moving. Once in 4th and 5th it pulls like a train. I didn’t push it due to it wasn’t warmed up yet but maybe a second better if I pushed it hard. Let boost reach 25 psi in 4th. Auto would probably be better for acceleration as you won’t loose boost when shifting.

What gear did you use for the test below

That was 4th. My favorite gear.
I wish I had the video of passing a semi going up hill on I10 in 5th hitting 90. Still the fastest I have let it get to.

Would it be any better if you started in 2nd, or skipped a gear?

I actually thought that as well but it didn’t help. Before changing high gear in TC I never used 1st and was a bit quicker when starting in 2nd.
 
Any stock cruisers out there want to contribute to this? I'm very interested in seeing the stock performance of the various engines.
 
'93 HDJ81, A442F auto, 285/75/16, stock turbo @ 18psi. 0-60mph looks to be about 12.7 seconds.

Couple of runs 88 Hj60 378000kms stock except 32in tires 26 sec 1/4 prob 200kilos of gear. Definitely not a race car. Anything more than 3/4 throttle makes no difference.
 
Turbophils 96 lx450 6bt VE pump non-intercooler 3.55 gears 305/75r16 a/t tires arb front bumper slee rear bumper winch and rock sliders and the 6bt with a343f using a car performance app ran a 11.5 sec 0-60.
HX35W ported waistegate set to 32psi

Didn’t do 1/4 but it will run 90mph happy down the highway with those gears.

My 4bt has been 14-17sec 0-60. 315/75r16 a/t tires intercooler 3.55 a343f depending on tune. 30-40 psi on an Hx30 46mm inducer

Now that you've run your fast trucks, you should give some of the others a try. Would be neat to see what the FJ62 and FJ45 run (if you still have them?). I'm curious how they compare to the diesels.
 
i want to try this out. anyone using a good apple app that’s free here? nice to use the same apps as others for best comparison i’d imagine the perfexpert costs like $13 which is a lot for an app ill use a couple times (maybe i’m just cheap but i’ve given apple more money than they deserve already!!).
