New JB4 Stinger Dyno Results!

[JDM_Man]

But it will still be better then regular 91 here

Sorry to revive this, but would I be okay to run my jb4 + regapped denso plugs + fuel wires with 91 pump on map2 consistently?
I've been running on map1 all the time, but im curious if I can just run map2 all the time.

Try it and look at the logs or post them.

I'm going to go out on a limb here and guess that @Terry@BMS is going to say run it and send the logs

edit: oh damn @Adamdan just beat me to it

I find it odd that BMS literally posted their initial JB4 Dyno's on Pump 91 but then its always "iffy" if you can actually run Map 2 on 91 octane, if its advertised on 91 pump it should be stable on that. I understand every car is different but literally if you market it for 91 lol.....

I would agree with that, if 91 was 91 all over the country / continent. Canadian 91 is probably like "good" US 89 or even 88. CA91 is probably in a similar boat. GOOD US 91 probably works just fine..

 

[YOWStinger]

And then there's our Petro Canada 94 which is like good Shell 91 which is like good US 89, so we basically just fill our cars with water and sand.

Can you verify your claim why Canadian 91 is US 88/89?

Thanks!

There's posts on it, even on Top Tier Shell/Esso 91 people are getting different results than on US 91 gasses.

Other tuners have actually said Petro Canada's 94 is actually like a 92 US gas.

Also note that the difference between Map 1 and Map 2 is only 14HP and about 27 lb-ft in the bottom end between 2250-5250.

With that being said is it worth damaging your engine if there is even a POSSIBILITY it could do damage?

Option 2. for Canadian Stingers or those stuck with 91 would be make sure you get an inter cooler and snorkels to keep your air temperatures down to help avoid knock. This is my plan!

Also on the note of 91 Canadian being more like 88/89 US, the 91 rating is how much it resists knocking so while it may not preform as well power wise it should technically be as resistant to knock.

Check out the JB4 Canadian stingers thread has more info in it.

I think this decision was made before plugging the JB4 in

The best mix I’ve found so far has been chevron 94 with E85 to make a e20 mix. I can run map 2 and 3 no problem. I was talking to one of the tuners down in my area and that’s what they run. They said even chevron 94 with a e10 has very good results. I have a 25L jug of E85 and I use 12.5L per tank. I don’t drive my car much so that one jug lasts me like two months.

While I would agree to only run the highest map as safely possible, and I intend to do the same, I believe our cars' knock sensors and algorithms should scale everything back enough to consistently run safely on the same fuel. Think of how our car undoubtedly runs best on 91+ in stock form, but nowhere does Kia state we cannot run on 87, everything is just scaled back, either timing or boost.

I don't think octane works like you think it works. If Canadian 91 is more like US 88/89, then it means cars on Canadian 91 usually perform like US 89. Higher octane fuels have LESS energy, but better knock resistance. That's the only performance difference - knock resistance. So Canadian 91 actually is NOT as resistant to knock as US 91.

I don't know what the difference is, in chemical terms - perhaps octane ratings are not as strict or as strictly checked in Canada. Or, in the US they "underrate" their octane. I used to feel all smug driving on Sunoco 94 in the K-W area for years, thinking I had better gas than most people in the US, only to find out that wasn't really the case.

Others have stated that they were able to tune higher on Petro 94 then US 91 so still confused. Guess someone needs to risk damaging their engine to send logs to terry.

Lots of speculation blowing around about 'inferior' premium gasoline in Canada - and I've yet to see any empirical evidence to support that.

Canadian gasoline has strict requirements for quality and content including the advertised octane rating, fuel is regularly tested, and I seriously doubt that the refineries have been pulling a fast one on anyone ...

I'm just going by @Terry@BMS 's posts, people running 91 in Canada aren't seeing the same results as people running 91 in the states. I'll look around and see if I can find the posts with logs.

That was one guy, who is also at like 5000 feet above sea level haha....He could also have something going on with his car etc...

I plan on getting my JB4 soonish and will do some runs to see what I get. Also I will do some dragy times and test different fules

-Petro 94
-Costco 91
-Shell 91

 

[YOWStinger]

Yup, just need more data. I'm also planning to pick one up at some point... some point after my landscaping is done and I get at least 1 oil change
