Doesn't look like they stated what octane rating the fuel had that they used for the dyno test

 

No they didn't...I am going to assume they used 93 because that torque number is significantly higher than what Fast Intentions and Stillen were able to produce on their dynos in California.

 

Side Note: @Bevo Horn, are you excited about Coach Herman...

I'm a huge college football fan (I root for Univ. of Southern Mississippi, TTT) and I found it absolutely amusing that UofH though they would be able to keep him if big brother (UT) came calling.

 

Heck yeah I am. I knew he was smart, but didn't know how smart until Colin Cowherd asked him about his Mensa membership. Not going to miss every answer given at a press conference with, "When you look at it..."

At the bottom of the article a reader asked about the octane used

 

We use 93 in NJ and maybe this was why I was so surprised and impressed with the 3.0t compared to my G35 and the many G37s I've driven as loaners. Interesting read, thanks.

 

Great find. I believe the RS 400 is also underrated as well if you dig around the Q50 forums.

 

Indeed it is...consistently dyno'd at around 375hp and 350 lb-ft/tq to the wheels...on 91 Octane gas.

Fast Intentions got up to 393hp and ~375 lb-ft/tq to the wheels with their exhaust application. Imagine what if a dyno is performed on 93, with this exhaust system, and an applicable tune (3.0T version as well)...

 

i feel that the RS is way underrated. I was pulling up to a light of 3 lanes of traffic the other night, see a Cadillac swing over to the right lane. One of those where right lane ends so I knew what that car was doing. So I set the car in Sport and punched it, was not gong to let that Caddy get by. Once i took off, the Caddy could not catch or get by,was 2 car lengths, let off about 80 after the right lane ended. Took a right at the next light and it was a 2013-14 CTS-V Wagon Black Diamond, which on paper should have blown my doors off. May have caught him off guard, but the RS motor is strong. Very impressed with the launch off the line.

 

Both the red and silver sport have been dynoed and they both put out more power than advertised.

 

In Washington state.

2017 Infiniti Q60 3.0t Premium is underrated, makes 310 hp at the wheels - TestMiles.Com | Automotive Industry News / Car Reviews

That's a little better on HP, but significantly better on torque than current dyno numbers performed in California. I assume Washington state has access to 93 octane gas, opposed to only 91 octane in Cali...

Can anyone verify the octane difference between the two states?

WA State is 92 Octane. At least I have access to non-ethanol gas.

 

Would throwing some octane booster in do any justice ?

 

I wouldn't risk jacking something up. If you just have to have more octane buy race gas.

Sunoco® FR™ is an unleaded oxygenated race fuel that performs well in turbocharged engines as well as air-restricted naturally aspirated engines that can benefit from an oxygenated racing fuel. It complies with certain race fuel regulations limiting oxygen to 4 volume percent.
Sunoco FR contains additives to enhance storage life. Sunoco FR will not harm oxygen sensors and can be used in any racing application requiring an unleaded fuel. As with any gasoline, FR should be stored in opaque sealed containers where temperatures are stable.

Does anyone have a summary of the tests?

 

What do you mean? I think they show the dyno sheet in the linked article...

 

It would be nice though to see some stock dyno runs of a 2017 Q60...

 

Concept Z Performance posted this today about the RS...

"We tested our brand new Q60 RS 400 on our Mustang Dyno! It put down 354whp and 353ft-lb of torque, which puts it at around 420-450hp at the crank. Infiniti is severely under-rating these from the factory! Expect to see about 370whp on DynoJets and DynaPacks."

 

So based on Wheel Horsepower to Crankshaft Horsepower Guestimator....

3.0t 310whp and 325ft-lb of torque = 372hp at the crank

3.0t RS 354whp and 353ft-lb of torque = 423hp at the crank

 

Doesn't seem fair that the Q60 300 is producing more that 300whp






Plus: "Expect to see about 370whp on DynoJets and DynaPacks."
