Fuel tests done by MOTEC - EVO IX

[bazeng]

While browsing the Motec site for a strain gauge I came across this interesting article..
Tested using an EVO IX.

Fuel testing results as seen on Network Ten's RPM Program
Summary

Fuel comparison tests were performed on three leading brand high octane fuels, Shell V-Power Racing and two Premium 98 Octane fuels (brands X and Y), under strictly controlled conditions. Tests were performed using a current model Mitsubishi Evo IX 2ltr turbocharged engine* mounted to a purpose built engine dynamometer cell. Tests were conducted using the standard Mitsubishi ECU and a MoTeC Plug In M800 ECU. No modifications were made to the engine.

The results of the testing clearly indicated that:

1. Tuning of engines is required to obtain the maximum benefit from any fuel.
2. There can be significant performance benefits to the fitting of a MoTeC Engine Control Unit (ECU), even without engine modifications.
3. Shell V-Power Racing 100 Octane fuel consistently delivered significantly more torque (up to 10.7%) and engine horsepower (up to 4.6%) than other commercially available high octane fuels in the retail market.

In addition, based on limited testing, Aviation Fuel (Av Gas) was also tested.
Initial results showed that V-Power Racing was superior in its detonation resistance and able to make more power than the tested Av Gas.

*Mitsubishi Lancer, Evolution IX, 4G63 2ltr, 16 valve DOHC MIVEC intercooled, turbocharged engine

nice find, interesting read.

Wonder why they don't state what brand the other 98 is? Is it because shell is part of the V8 supercars...

 

[evopwr]

that, and shell probably sponsored their test and gave them some 'incentive' money.

that, and shell probably sponsored their test and gave them some 'incentive' money.

in which case its a biased trial and the results dont really mean anything :lol:

DERRRRRRR................

They tested V-power 100 octane vs two 98 octane fuels.... of course the extra 2 octane level is going to make a little bit more power!! :lol:

Why dont they test 95 Octane Shell vs 98 Octane generic and show us the results

 

[evopwr]

I was surprised that they said aviation fuel produced the same results as 100RON Vpower. I thought AV fuel was like 104 RON?

 

[bazeng]

My guess is that the other 98 fuels would be BP and MOBIL being the next biggest 2???

I don't think any other company does 100ron out of the major 3?? or do they?

I guess its a comparison of the best fuels that you can get at the pump hence 98 vs 100

 

[DOUGMO]

no shell 100 anymore anyway
it was 10% ethanol like the united stuff and thats why it is good
at stopping detonation, I think the issue is that when it was available there was still alot of anti-ethanol talk about so they canned it.

Trial 1: ‘Standard ECU’
Using the Mitsubishi ECU as if fitted to the standard vehicle with standard
Turbocharger boost (14psi). This resulted in close to 1% variation in peak torque
between Premium X 98 Octane and V-Power racing 100 Octane

^^^^^^^ correct me if im wrong but stock boost for a evo 9 is 18??

 

[Jonson]

Yes, thats wrong.

 

[JiMi]

just a guess but would it be the pressure the wastegate opens at with no electronic control? protective thing to stop overboost if there is a failure?
