FR-S Dyno testing at DD Performance Research inc. 2ZZ comparison
 

We strapped the new FR-S down on the dyno last night with less than 150 miles on the ODO. (probably a few more ponies on the table once it is broken in further - we will dyno again at higher mileage).

Run 004 was in 3rd run 007 and 008 were in 4th:

Run 010 was in 5th, and we saw a huge jump in mid-range torque, despite a richer afr. These were sampled at the tailpipe min you so they are post cat readings.

A comparison between a 25K miles stock Elise with the 190hp tuned 2zz-ge and the new stock FR-S:

2zz also had a 10% better final drive, the car feels as fast as my Celica but the frs def has more tq

looking good! love that TQ~!

wow, there is a big difference in horsepower from 4500 to 7000 rpm not to mention the torque all throughout. Plus this is comparing to a tuned 2zz.

Too bad the Elise has a 700-something pound weight advantage ;)

Its the Lotus Factory tune. It just makes 10 HP more than the toyota factory tune does.

I would say you defiantly feel like you have more power after 200 miles on it. or it could just be i konw how to drive it better now :)

I miss the kick of my vvtli, and the GT-S still feels faster. But a lot of faster cars somehow feel slower than the GT-S.

How fast a car feels is mostly in the gearing, but variable valve/intake magic will do that too.

gggooooooddd this thing has more HP than my lude even though it suffers more drivetrain loss. the fkkk!!!! torque is aroudn teh same though so im happy about that

nice dave!

Definitely a bit better powerband than the Elise. Can't really say if it's 'faster' though.

Track numbers to go with the dyno numbers:

We took our new FR-S to the track today. It was pretty hot most of the day, but we wound up with some decent times.

Here is the best of the night with our FR-S full interior full vehicle weight (including spare/jack) With a 10-15mph headwind and a humid 84*F, Car # 592;

Here is the best of the night with minor weight reduction (spare & jack removed, rear seats removed) & intake filter removed with a 10-15 mph headwind and a humid 80*F Car #592;

http://www.ddperformanceresearch.com...20headwind.jpg

Both of these were with Jason (My shop manager) at the wheel. My best for the night was a 15.10.

All in all I am pleased and unsurprised by these numbers - they are exactly what we expected from the dyno and articles already published.

Nice - any videos?

Yes boosted took a few videos, and I took some of him as well. My Fiance I think got vids of all the runs.

Should be able to get those up on our youtube channel later.

Here are the corner weights for the two types of runs (full weight / minor weight reduction)

rear seats removed, spare tire / jack / tools / floor mats removed, with 1/4 tank of fuel:

+/- 2% accuracy

vehicle weight: 2652.21 lbs - 2852 with driver

Passenger side | Driver side
Front : 775lbs 29.2% | 746lbs 28.1%
Rear: 555lbs 20.9% | 573lbs 21.6%


No weight reduction, 1/4 tank of fuel:

+/- 2% accuracy

vehicle weight: 2722 lbs 2922 with driver

Passenger side | Driver side
Front: 789lbs 29.0% | 734lbs 27.0%
Rear: 597lbs 21.9% | 597lbs 21.9%

Here is the video of the FR-S against a Hundai genesis 360 coupe:

[ame="http://www.youtube.com/watch?v=8Cy3vh7LKb4"]DD Performance Research's 2013 FR-S minor Weight Reduction 14.7 1/4 mile at 92.2 mph - YouTube[/ame]

I did read car and driver magazine cracked a 14.9 from their test car - don't know the car specs or track location. Yours is good for hot n humid conditions

Motor trend also tested the FR-S and BR-Z
They got 14.8@94.4 for the FR-S and 14.9 @94.3 for the BR-Z.

They don't list the conditions or vehicle weight for their testing, but it is interesting to see that they achieved simmilar ET with much higher MPH (94.4 for 14.9 vs our 91.11 for 14.9)

In cooler weather without a headwind I can see the full weight car doing a 14.7 @ 94 mph if driven well. I also see a 14.5 @ 95 mph with some minor weight reduction in the same cooler "ideal" conditions.

Can't wait to see what you guys come up with for the BRZ/FRS. You have done great things for the 2zz.

We finally got 2500 miles or so on the FR-S and got some fresh oil in the car. Here's the updated dyno and our new baseline:

http://www.ddperformanceresearch.com...20dyno%201.jpg

Both runs were done in 5th, and runfile 007 is the last dyno we did in 5th while the motor was still new (250 miles or so). Runfile 015 is after break-in and fresh oil

So how the hell did best motoring get a 14.3?

I think they did a 400 meter run which is shorter than a 1/4mile by 18 feet. Shorter distance = faster time.

wow, pretty big improvement after breaking it in!

Just wanted to say that I followed your research very closely when I had a celica and you guys know your shit! I expect great things from you and I hope you have fun doing it :)

Nice, thanks for posting.

Just saw this!

Thanks for posting this up.

I think the gain is most likely from the advance multiplier increasing allowing the car to run more timing.

So Im guessing that we have to drive the car until it reaches about 2,000 to 3,000 miles on the ODO to get more hp & tq

Yup - this is normal. As motors loosen up and break in they make a little more power and get better fuel economy. I've had some new cars still gain economy bit by bit all the way to 15,000 miles before they plateau.

wow runfile15 is nice (170hp)

I suspect it is a combination of things.

First, I only run shell and chevron 93 octane, so it is likely that the motor is not having to pull any timing for knock response. Toyota's ECUs actually start at Maximum timing, and then they use a long term and short term knock trim to pull timing back out to the currently desired level. You can reset this value by resetting the ecu (disconeccting the battery). Those values both exist in the FRS ECU when viewed with a Toyota Techstream scantool, so I suspect it is the same as the rest in that respect. Now there MAY have been some fuel related timing reduction for the first pull, but it did have 93 in the tank from an Exxon station across from the dealer.

And a good deal of it is from break in. We actually felt a huge difference after we took it to the drag strip at @300 miles or so. We made over 16 runs, and about the first 12 were literally back to back. The next day there was a definite increase in power. I have also seen a corresponding increase in fuel economy even when driving hard.

It should be noted the ambient temps were warmer on the more recent pulls as well.

we had one run that was even higher, but this one was the closest to the middle of the pulls we did this time around.

So, this means ~15% drivetrain loss assuming the engine is truly putting out 200hp at the crank?

Not too shabby. Eh?

Although that might be the case for Toyota ECUs this is not the case for Subaru - the ecu in these cars.

After ecu reset the car does not run maximum advance. Car needs to e given a drive cycle and go thru some things in order for the advance multiplier to jump up allowing maximum advance.

By default the advance multiplier is at .7. Car won't see full advance until the advance multiplier jumps up to 1.0

I thought they both use Denso?

Not bad numbers at all.

I wonder if a full exhaust on this car would raise the HP from
170 to maybe about 5-10 more horses or just stay the same ?

Is the table temp based? Or load based? Interesting...

haven't been reading much, Nameless has seen >20whp from their full exhaust and Vtune has another 18wp gain from tuning, I'm sure if you tuned in the full exhaust and an intake you could see >40whp gains

That would be incredible; same lvl of gain seen from the K20 in my RSX-S.
I would be seriously impressed with the boxer & DI if it could manage that =D
Here's to hoping for the best results!

Would be VERY awesome
