Crd Shell 100 Testing

[CRD]

Hey Guys,

Here is dyno sheet of a R33 GTR with a new engine we built with R34 N1 turbochargers with before and after of 98 and 100 octane shell fuel.

Car is used for circuit only.

i pressume the increase is the 100ron

thats good enough proof for me....

ill use it!

[CRD]

That is right but if you use it you need to retune the engine as the 100 uses 2 percent oxygen therefore the engine will run leaner.

yep good enough for me .. id drive it

understandable..

is it already available or was this a sample for testing?

so is this fuel here to stay?

or is it ok to use it on stock cars?

[satanic]

Question:

You guys say that the car needs to be re-tuned if you use the 100RON fuel right? If not it may/will cause damage due to the engine running too lean?

My question is how you get the car to the tuner once you fill the car up with this stuff (100RON)? Granny it to the tuner? Obviously I'd need to drive around to burn off the excess non-100RON fuel first right?

Interesting results Jim, thanks for posting the dyno sheet up

Sounds like something better used in cars with aftermarket programmable ECU's rather than the stock computers

Jim: what do you think about nissans claim not to use it in any pre 2004 cars? what do you think of the ethonol in RB26's?

[lwells]

My 0.02c: not enough places stock 100RON fuel to make the effort (and cost) to retune for the time being*.

A question for Jim: if you tune for this new fuel, what do the AFRs look like when you stick 98 back in (without altering the tune again)? I would assume rich, but how much extra timing (if any) did you wind in?

* For me, anyway. None of the petrol stations are anywhere near me, and the last thing I want to have to do is drive around like a granny looking for a Shell stocking 100RON fuel.

[ecl]

might give it a go seeing i need to get my safc tuned anyways

stay posted for results

[Cubes]

Quite a substantial increase.

I'll be using it when its Available in SA.

[siksII]

i wouldnt get it tuned for that just for the fact that u cant get the fuel from many places, so if you go for a nice drive out to a small town of something, you wont get the right fuel. ok for a race car or something you never drive far.

[midnight]

you could run a dual map setup.

Then just switch over for different fuels.

[Links]

Problem with that midnight is you would get a mix of 100RON and 98RON and have a crossover period.. but that's about it..

What about running it in a Stock R33 - resetting the ECU - they run rich as they are - but would the timing need to be changed?

[red900ss]

That is right but if you use it you need to retune the engine as the 100 uses 2 percent oxygen

<{POST_SNAPBACK}>

Shouldn't that statement be:

"To make the same power (as 98) with 100,and have the correct mixture, you need to retune the engine as the 100 uses 2 percent more oxygen therefore the engine will run leaner." or something like that

Please correct me if I'm wrong, Jim. Putting 100 in a car tuned to run on 98, 95, or 90 will not make the engine run leaner, it just wont burn all the available fuel.

[DoughBoy]

I think Jim's referring to the oxygen content in the fuel not the fuel being more dense/requiring more airflow.

[Beer Baron]

40 killowats aint to bad at all Jim. Has anyone checked the price of the 100ron vs optimax? Certainly seems like good value considering you got more than 10% extra power out of this GTR.
