Very cool Ramon, how stable does the rig feel at that speed. I stopped at 80 with the 62, I did not need to push past that.

The 62 went home to Alabama
70's about all I would do in this SWB truck on SOA and worn out tires. More than plenty for what I will do with it.

I can see, due to this performance, a road trip in Ramon's future...a LONG road trip...
I would not like to think about how hairy it would be if I was sprung over but with a firm sprung under setup I'm very stable at 80. Most it has ever seen is 100. Obviously not as stable but it wasn't acting up either.
Dyno tuning session scheduled for 1 week from today. Exciting. Between now and then I aim to:
- Dump the break-in oil for fresh with filter (of course)
- Valve lash check/adjustment (since new cam and lifters)
- Clean up some stuff underneath - need to get the bell housing and flywheel cover painted with POR15 or Rust Bullet since the spray paint flaked. Should be fun upside down.
- Get the passenger seat mounting finalized
- Maybe fresh plugs since with my current tune she's been running rich quite a bit
- May need to address the fuel pump - it's awfully noisy to me, and hasn't always been that loud
I think I will easily hit those numbers. Most 2fe threads I've seen estimate a bit more TQ than a 1fz with less HP and that is running a stock ecu and a very restrictive Air flow meter.
With your MAP and tune I'd say you will hit them

I am looking forward to seeing it in person Ramon, I am thinking you will be posting some good numbers.
Pretty damned close guess I had above. I'll attach the dyno chart once they email it to me, but 143HP / 207ft lbs at the rear wheels. Should equate to about 175HP/252ft lbs at the crank. Beautiful curve... Torque was over 200 from when the chart started at 2kRPM all the way out through 4k RPM. Super flat! Stoked.
You may be higher at the crank than you think. Trucks with large tires/wheels always seem to score very low on wheel HP vs crank HP. I've seen jeeps with crate 350s rated at 300hp and large tires score 40% lower on a wheel dyno at my friends dyno shop back home.
This post has a few 1fz dyno charts on it and you scored higher than they did. (I know different drivelines but just saying crank hp is hard to gauge on these things)

Either way those numbers are great..... Can I sign up for a ride at the meet and greet??

Absolutely Al! The "seat of the pants" on this thing is very pleasing for me. Thanks for posting that link, I'll have to give it a read. I'm really not all that interested in the final numbers, instead the the curve... and that was VERY gratifying. You would have been a kid in a candy store that shop (albeit mostly blue oval).
I do have that inspection cover if you want it.
Here's the dyno chart. Unfortunatley, the version they sent me hides a good portion of the torque curve with the legend. I'm trying to see if there is a better version they can send me. Also, I asked them to start the curve earlier (around 1k) and I guess that didn't happen either. But, as a synopsis, I'm making peak HP 3800-4200RPM, but the torque is available way earlier in the revs. That's what I was after for the most part. I'll update this if I get a better version:
Am I starting to obsess with my results???
My run was done in 3rd gear due to the tire size (and condition). I just read this...

If you weren't obsessing you wouldn't be a land cruiser owner.
Regarding results, you had no choice, i.e. No real way you could have pulled another gear. I would enjoy seeing several pulls done with nothing different but tire size. On paper it should not matter since a torque gain in one place (say a smaller tire) would be offset by a loss in another (eg higher gear) ... But from what I have read the numbers really do come up different.
Still, don't obsess too much. Those really are good numbers considering we dump all our torque out the rear of those awfully inefficient offset transfer cases.
