Good stuff... will be cool to see the power curve comparisons/overlay.

That’s getting emailed to me

 

[NLXTACY]

We need video footage for each one also.... For science.

....Ok I just wanna hear them back to back

I have the videos but I need to post to YouTube first

 

[NLXTACY]

121 is pretty much in line with what was expected!

Thanks for getting us the baseline number......no nobody will go crying home to Mommy.

Bingo

Absolutely right Dan, I would expect if you pulled the front driveshaft and locked the center diff and ran the truck in 2wd, I think you would see a bump in hp, but I don't think it would be huge, just a guess but maybe 8hp.

I'm waiting for Ryan to chime in here. All-wheel power may be different than rear-wheel power?

121hp damn, you can squeeze more horse than that out of a V-twin! I thought it would be higher

 

[NLXTACY]

And the deets!

You can thank the most inefficient drivetrain this side of an Abrams tank for that.

lol true. However stick a V-twin up to the 80's drivetrain and maybe see 45hp at the wheels. Build a bike around a 1FZ-FE and HOLD ON......no really, hold on because that motor is a tall heavy beast that will crush your leg if the bike falls over.

121 to 173 hp, 43% gain, that's nice!

 

[scottryana]

You can't after AWD drivetrain loss. That is the part people forget about. I have posted a couple LS swapped 80's that were on the dyno and the numbers were not as impressive as everyone thinks.

Nice work Joey! Looking forward to the final product!

 

[scottryana]

No this graph just shows the before hp and torque. 121awhp and 170ft/lbs to the wheels. The after turbo dyno has not been done yet.

So.... When is the turbo getting put on & another dyno run?

Is it the transmission or the transfer case that absorbs so much of the energy? Anyone out there with a manual trans stock 1FZ dyno run?

I'd guess the automatic transmission soaks up a good amount but it's also the incremental losses all the way to the wheels. Consider all of the gears, U joints, axles, etc..

 

[cruiserdan]

Every time the power takes a turn after it leaves the crank something falls off.

 

[scottryana]

I don't have a lot of data on manual Gen I 1FZ trucks, the one manual H15x I know of dyno'd about 20awhp higher than the autos. So percentage of loss would be like 35% for the auto and 28% for the manual, makes me think there is quite a bit of loss in the transfercase and axles.

Wait, no. You are looking at hp/torque. Not before/after. I still need the “after”

Especially cold weather. Remember front birfields are turning in a giant ball of sticky grease!

Somewhere on Mud someone posted a Mad Max meme, “A343F: 2 hp enter, 1 hp leaves!”
