Has anyone actually dyno'd a 2F or F135? (1 Viewer)

More out of curiosity than anything, but has anyone ever actually dyno'd a stock 2F or F135?

I'm curious as to how much horsepower they were actually putting out, and, more importantly, how much is actually getting to the wheels.

I did a search...

I think 85hp at the wheels for 2f.

That's about what I was guesstimating. Thanks!

We dyno'ed during Header testing, 120 h.p. off of crank shaft, and you can loose between 20% and 40% before getting to the rear tires, so White Stripes number above is very possible.

My 2FE dyno'd at 143RWHP - that is with a delta cam and internal balancing. They didn't trust my tires so they did it in 3rd gear too, so I'll have that redone sometime in the future. Unfortunately, the legend hides the torque curve, but you can tell it's around 200+ up through around 3500RPM where it starts to drop off some

Those are good numbers, Weller. Was the engine running the 3FE head/manifolds, etc? And a tuneable MS ECU? Airflow meter or MAP speed density?
It would make even more tork from 2500-4200 if AFR is brought down to 13.0

Hey Jim. It's setup with MAP on a MS2 controller. I know you really know these motors, so if you are saying my AFR needs to be closer to 13 for that range, I'll give it a shot. Are you saying only up around 100%VE and taper down with load?

Right now I have the target AFR at 13.5 for VE>80 for the entire RPM range.


ETA - this dyno run was early on in my tuning. I can't recall if my AFRs were adjusted after that run, or if they were just off the mark here. But, looking at that chart I see why you made that comment for sure. I just looked at a log from a recent drive, and I'm pushing much closer to the 13.5 target in that upper VE range, across the board. Thanks!

I did read genuine Toyota specs years ago (don't remember the Toyota source piece though) that the F engine was 120 h.p. and 240 ft. lbs. of torque.

Dynos can vary a lot. Unless a person does a before and after Dyno run on the same Dyno then their is no telling what actual output is.

I dyno'd my 2F before, and after I rebuilt the engine. Not that I expected a huge jump in numbers, just curiosity. Picture shows the difference in the two. Done in Denver 5280' above sea level...

Got to love that flat-as-a-board torque curve!
