Race fuel: The truth! We dyno test pump fuel against Gulf Racing 102 and the results are shocking!

- Is it worth spending the extra money for race fuel, even if you have a stock bike? Or is super-unleaded pump fuel good enough?
We take a brand new stock 2022 Husqvarna FC450 four-stroke and a mildly tuned TC250 two-stroke and try fresh pump fuel versus Gulf Racing 102 back-to-back on the dyno with a stock ECU map and then with a remapped GET ECU. And the results are truly surprising.
And no, this video isn't sponsored by Gulf! - Auta a dopravní prostředky
Cool but where's the data!? 😜
Agree, have the GET on a KX450 and with a JE Pro piston (13.5:1) and stage 2 hotcams the difference is massive. More torque, more over- rev and smoother.
All that and no porting that’s a waist don’t you think ?
I have a raceway nearby with sunoco 110 available. I have been mixing it 3 gal 91 and 2 gal 110...
Do they do a pre mixed fuel for the 2 stroke?
Doesn’t smell like race fuel more like BS. Should have ran both fuel without ecu. Then tuned the ecu with both fuels.
Then they wouldn't be able to sell you fuel lol
What happened to the two stroke?
Can you use this in stock 4t
on the 2 strokes?
Race Fuel is the only way in my book. I Ran Vp T2 when my 2022 tc125 was stock, now i run VP MRX02 now that motor is fully built with custom tuning CDI
So the REAL question is, do they mix 95 octane and 100% Ethanol or do they use under 95octane poor quality fuel and calculate the approx octane rating after adding the 10% ethanol? For example before EU shit: 95E, after EU: 92-93octane cheap and poor quality+10% E=95octane mix?
Is it right that Gulf Racing fule 102 , have a Octan 95,26 ..
Most people have zero need for any race fuel when they ride around at 1/4 throttle. Same for engine mods and pipes etc, because a fast kid on a 65cc can smoke most with a 450.
@martin barr's CRF450 I'll be honest there are kids on 65s that are way faster than weekend warrior guys that are on bigger bikes. It's all comparative though and it also depends on your definition and opinion of a novice 450 rider.
@martin barr's CRF450 We're not talking about a straight line drag race, we're talking moto and woods riding. I know many talented kids on 65's that absolutely smoke 450's on the track.
Heavier, more dense compounds promote mpg. Lighter compounds, less dense compounds and those with attached oxygens reduce mpg.
More carbons in an atom = more mpg.
Toluene is your friend 👍
We wouldn't mind the gulf stations having at least 1 pump
Is a leaded or oxygenated race fuel better performing on the two stroke, especially if you run a high compression head insert?
Oxygenated fuel is always better from what I heard. I have a 2 stroke ktm and 4 stroke Yamaha (Yamaha is bone stock). I run Sunoco 110 mix with 93 pump gas and I also add Vp unleaded additive in my 4 stroke and the leaded additive for my 2 stroke. I don’t think you’ll notice a difference running leaded fuel or oxygenated fuel (one or the other not mixed).
Why don't you use leaded race fuel?
Cancer
Less benzene no mothballs Pure clean as can be developed??
I'm Thinking Thor on the Merlin Motorsport have a 50% at least hydrogen mix with Clear vegetables based VG and or just PG vape oils fuel
I still don't get the whole flap about e10. I understand the risks of having ethanol in the fuel, but it's already had 5% in, for years.
Ethanol is less energy dense when compared to petrol (gasoline) it burns hotter than petrol and it’s also more aggressive on the fuel system..(gaskets, seals and other plastic parts)
@@Shoorit Ethanol actually burns colder then petrol.
@@Shoorit We run straight ethanol in our USAC Midgets and Sprint Cars and building heat in the engines is a challenge some times.
@@backcountryme I think what I had read was about ethanol blends, there had been complaints of overheating issues but I’m not sure that’s true as I do know that straight ethanol has a cooler flame than gasoline.
who is using e10 , 95 fuel, show me what its like with 99 octane pump fuel
Why at least 1 pump at the gulf doesn't stock 1L or 5L (Aspen 4t) station should have that fuel to fill out a tank or mix part e10 or premium

Interesting vid, but these race teams are crack up really.... trying to get "more power" out of a 450.... reality is most pro riders want a stock or de-tuned engine on the 450. Riding a 450 fast is all about slowing them down haha.... counter intuitive but they are such a pig of a bike its true
I hear you and agree to a point however most factory teams build a engine which is faster and more rideable believe it or not 👍🏻
@@davewillet4764 Yeah i would say a pro rider could ride a fairly stock bike just as fast, but not for long. It seems the factory teams objective now days is to tune the power curve/chassis/suspension/rider relationship so as the bike is more forgiving, and can be ridden fast the entire moto. You can see it in say MXGP, the non factory riders are fast for half the moto and then fade... the factory boys are fast the entire moto, their bikes are more forgiving of mistakes and just easier to ride fast... I feel since 450's came in, a factory bike is absolutely a big advantage
Tomac is asking for more power this year
@@KosmicHRTRacingTeam i believe the deal with Tomac is he has left the engine as the team supplied it ... opposed to wanting more power... where as all other riders have wanted de-tuned mapping
@@daniellewis6976 with Tomac, the team has a base map that they use and change to suit a rider and Tomac is the first person that has asked for more power instead of a de-tune.
Also, these team aren’t just looking for HP gain they are working on a dyno to create a map that suits their riders.
I believe this video is just showing what they can do with a map and exhaust when in reality there’s so much more to what they do.
wow! at £4.90 a litre not only would I want some horsepower gains but rainbows and fairy dust to come out the exhaust. I love my 2 stroke but with the way things are going Stark may just be the future
Here in germany we can get 110 pump gas.
110 Oktan wo den? Aral hat 102..
@@thomasd2680 110 oder verwechsel ich was?
Ok... hast recht sind 102😆
