So is everyone good with running 87 octane fuel or are you going for better grade ? If so how much higher and what are the benifits ,,, thanks

You will be fine with 87. The higher octane gas is for the higher performance machines. On my 450 I wouldn't run anything lower than 91. The higher the octane, the more it can be compressed before the gas will ignite. That is why higher compression piston call for it.

I can't run 87 I can get away with 93 but my quad really like 104 racing fuel.

 

[Redracer]

What compression are you running?

 

[TRX2fiveO]

12:1 @ 50 over 87 will run but I don't have the performance so what I generally do is mix 93 and 104 only because 104 is 8bucks a gallon...lol

When you use 87, expansion occurs when the piston is farther along in its downstroke and thus there's more room in the cylinder head. This reduces peak cylinder pressure, eliminating knock but also giving you less power and poorer mileage.

Poor mileage is right I ran one tank of 87 and it didn't last no time I can run the 93/104 mix and it last a good while. that and my engine seems to run a bit cooler.

I run 91 I can get 55 miles out of one 3.9gallons tank on my 450 at race pace. I've never tried a 5th lap on the original tank.

Higher octane gas makes ANY engine runner cooler. That why ppl who boost (turbo) cars use meth injection cools down the detonation temp. = more power son!

I wish my tank was that big i think mine is right at 3 gallons

 

[Redracer]

Sorry, that was a typo. I have a 3.1 with res.

I was looking at the 3.9 tanks from IMS

 

[flcb7]

mine is 17 gallons...ha!

 

[Redracer]

mine is 17 gallons...ha!

That would be one heavy arse quad when it had a full tank.

 

[flcb7]

Yeah @ 8lbs a gallon that would be heavy...but I was talking about my Honda accord...lol I saw the opening I just had to say it.

 

[TRX2fiveO]

Lol ur Funny got pic of the 17 gallon Honda??

[flcb7]

that was be4 the rims and paint. I dont have any newer pics. But paint is the same color and I put 94 accord ex 15 inch rims on it. With a build h22 prelude engine swap
it looks ALOT better with the 15s it kinda looks crapy with the 14' steelies on there

Getting ready to swap the engine for a 98 GTP Supercharged 3.8. Since this pic I have lowered it 2 more inches too.
