Turbo/Supercharger on Canadian gas.
 

Hi, this is my first post so sorry if I do something wrong. I'm looking at getting my car supercharged and was wondering what kinda power you guys make with Canadian fuel safely. I'm in BC so I do have Chevron 94 available. Thanks.

My car is tuned for 91oct. Runs fine on BC gas. You should be fine especially with 94oct. I'm should be making around 270whp on a jdl turbo.

I'm turbo'd and was initially running 91 - 'only' dyno'd at 270whp
I made the change to 94 and it bumped me up to 300whp (both at 10psi)
I am also set up for flex fuel - once I can source some e85 (that won't break the bank....) I should be able to pull about 400whp

Our chev94 is supposedly worse quality than chev92 just across the border. That said it's still the best you can get here even compared to shell 91.

OP, I would contact Drift office in Washington. Bob Watanabe is well regarded in our local 86 club for being the guru for any sort of tuning or boosting needs and will get you going down the right path.

The only way you will be able to get E85 in Ontario is too buy it by the drum. Not cheap and requires special handling equipment to store and dispense it without blowing yourself up.


Why would the octane level have anything to do with quality? The higher numbers do not reflect the quality of the fuel and 89 can be just as good as 94 as far as quality goes it just has less knock resistance. There is no real difference in the "quality" between the two countries if you stick to the top tier stations.

Yeah I know that the octane rating isn't indicative of quality, but pretty much all of the local tuners here have sworn by US92 (or costco92?) as getting more horsepower out of the same tune and less knock than our 94. I'm just going by the local consensus here. This isn't just for the 86 platform, but for the local subaru group as well. The ranking seems to go US92, Chev94, Shell91. 94 is the only ethanol free fuel you can get here, everything else is "up to 10% ethanol".

Some people suspect that since 94 isn't a very popular purchase here outside of enthusiasts that many of the stations will have it sitting in their tanks for a long time and the fuel has degraded and has excessive condensation buildup. Some go as far as picking specific stations that they know have a high turnover rate.

Whether or not these claims have merit, I'm not 100% sure myself as I am not in the tuning business nor has my car been tuned. I think OP should still discuss with a local tuner, tell him exactly which fuel and setup he plans to run regularly and tailor that tune to suit their needs best.

Also we can now get E85 locally from: http://www.northsidepetroleum.com/e85-ethanol/

Sign a waiver and they will pump directly into your car. No idea on pricing as I have never purchased there myself, but I bet it isn't cheap.

Now that makes more sense! It read like you felt there was a quality jump with octane.

It is funny how they push the flex fuel vehicles here but you can't get e85. Not sure what the waiver is all about. Many cars on the road are flex fuel from the factory now.

I think it's to weed out the clowns who read online about "mad gainz on e85!" and want to put it in their vehicle that isn't set up for flex fuel. We have all heard about people putting diesel into their gas cars because it was cheaper at the pump...

Yeah...that’s what we have been looking into. We would have it set up at my husbands shop

Thanks for all the feedback!

Touge Tuning in Missisauga made E80 for the subaru wrx/sti
Im assuming they have flex fuel now? if this is true I have alot of questions to ask them very soon...

They sell by the barrel, or pump it out of a barrel for you. You'll be paying a big premium for it. Longterm it'll be cheaper to build the engine to make the power you want on pump gas vs constantly paying double the price for gas. If you're not running it all the time it's not a bad option.

They stated $2.50/L at one point, not sure what the current price is:

Is anyone else from Canada/GTA running the 210 supercharger with 94 octane? Pulley upgrade? What are your gains lets see them....
