Hybrid vs. Gas Non-Hybrid Dyno Comparison - Stock HP / LB-FT Real World Numbers! (87 Octane)

[FoRunna]

For those who are curious about the difference in output between the Hyrbid and non-Hybrid powertrains, here's what you can expect;

We put two identically spec'd Tacoma's on our Dynojet chassis dyno a few weeks ago...except one is sporting the Hybrid I-Force Max engine. Both were on 87 octane.

The non-Hybrid produced 273whp and 311tq, which is higher than anticipated, considering these numbers are essentially what Toyota rates the powertrain at, and those figures aren't at the rear wheels. The Hybrid produced 297whp and 374tq, which is in line with our expectations.

Though these engines have been out many years, there has been little progress made on the performance front. We're hoping to find out how much more Toyota left table over the next year or so.

Is this with regular or premium gasoline?

Both were on 87 octane.

Shouldn't the HP and torque be much higher on the hybrid? Since Toyota claims 326hp/465lbs...

Manufacturers rate power and torque at the flywheel, not at the tires.

Hybrid is quite a bit higher. We're gaining about 24whp and 63 ft-lbs of torque, which is a nice amount.

Thanks for the knowledge!

Now we needs numbers with 91 octane.

You might get lower numbers with higher octane. Higher octane does not equate to higher HP/torque. It is to prevent detonation caused by higher compression. Running the lowest octane before detonation will usually get you higher performance.

In reality, you get a power boost due to the 2.4 being a higher compression turbo engine.

It can take advantage of the increased octane rating.

You can definitely feel that extra 64 ft-lbs on the real world. It comes in really early on too and that's what counts.

This guy explains it well. The Taco's ECU could take advantage of the 91 and the compression of the engine. I raced super bikes for a long time. Another gain was to run non ethanol 91. Our bikes were high compression and most guys would run 93, some higher but the 91 lower octane and ethanol free would always make more power.

Finally. A racer who understands power! More is always better.

Especially 2 strokes! Just sold a 75 RD 350.

Is that an old photo of Kevin Schwantz? Mad respect for the nuts who raced the old smokers.

 

[FoRunna]

It'll be interesting to see what it does on higher octane fuel, but I don't expect that +20whp is a reality on fuel alone. There doesn't seem to be any indication that it's pulling much timing (if any at all) on the factory tune.

That said, there's certainly more in the proverbial tank and we're going to find it.

Seriously?? I still have mine in the mini barn. DG heads, Martek electronic ignition, Denco chambers, ported, forks and shocks. Screamer
