View Full Version : 76 Racing Cool Blue
Is it possible to use a higher octane fuel in a car than recommended by the manufacturer?
Would it be possible to run 100 octane or 106 octane Cool Blue, in a car that normally runs 95 octane super unleaded?

If you can make the most use of it by a suitably mapped car, don't see why not.
You could run a very aggressive ign advance :)

Before you start getting to oexcited about all of this, have you investigated how much this stuff costs? I was talking recently with a chap who races in the 750 Motor Club Stock Hatch series about something similar and he mentioned some prices... :eek: :shock: :yikes:
Too right Glyn, knoeck yourself out by looking at the prices for 76 Racing 106RON unleaded petrol www.76racing.co.uk I think I worked out a whole tank would cost me over £200!

One thing to remember, if you engine isn't retarding the ignition due to detonation then higher octane fuel will actually make your car SLOWER! So, if for example you put Optimax in an untuned Clio 1.2 then chances are it will actually reduce the performance!

Hmm. not sure how this fits in... but my observation.
Mrs B has a 1.0E Lupo... gutless. 50bhp.
It loves optimax and runs significantly better on it, and does have better response and engine pull.
Small motor.. not tuned for power but it reacts well to it.
Probably a high CR motor..

That implies that the Lupo is detonation limited too then! Surprising though, as many NA engines have a specific output of anout 90bhp per litre now and so 50bhp per litre shouldn't be too much to ask!
See the first paragraph in the section called Engineering Data on the following webpage:
http://www.merkurencyclopedia.com/Fuel/fuelchem.html
It may be that its not the Octane rating of the optimax that makes the Lupo run well, its maybe the other stuff in it.
So, how come Mrs B gets a 1.0 Lupo and you get 350bhp and 400bhp monsters!!! :D :car:

Thats why Mrs B is pining for the Golf back.... she likes it more than me... but it is me who pciks up the bills so my love for it is somewhat tainted at the moment.
Mrs B has a 1.4 16v motor which I have just bought for her Lupo, and it will receive the badger5 throttle body treatment when installed. 140bhp then, which should keep her happy in her ickle Lupo.

A 55l barrel of RFT from 76 cost around £180 delivered, at least I think that's about what I paid last time. Good stuff though.
Sounds like expensive, but good fuel!

Good man! 140bhp in a Lupo is good!
Kev, is there any software for the Lupo GTi under development?
Edit: Just found out that Jabbasport only do remapping of forced induction vehicles.
Bill, what tuning do you do for GTi's? Please, please let me know!

Mrs B should be happy when its done... 1.4 16v is a nice unit from which to build from. Good potential.
I use DTA ecu's on conversions & throttle body kits so this is what I will probably do for the Lupo. Considering also retaining the stock ECU and trialing something like the Uni-Chip and keep fbw throttle.... Needs more investigation tho.
If you mean GTi, as in 8v or 16v, and remapping of the stock ecu, I would advise Vince @ stealth racing as he uses Geoff Everett (Mr AmD of old)

If you try the Unichip route I'd love to hear how you get on.
I've looked at this but given it very little thought for a future conversion using your kit, but the thing that puts me off is I've heard of nobody using a Unichip let alone doing something like this. I'm all for ground-breaking but not this time for me.
I've also looked at retaining the stock management on the ABF but I'm getting conflicting views and am erring to think that it just ain't up to the job.
Its thinking ahead but I want a remap of the stock Lupo GTi ecu, a stainless steel sports exhaust including a highflow cat and a good induction kit.
Does a remap involve opening the ecu box?
The Lupo GTi box is filled with glue to prevent tampering and breaks the boards components during opening if its tried. Please tell me its done by wire and just a flash memory change to the cars software.

I don't see why it would be tho... It should be feasable. TPs vs crank sensor with compensations for air and water temps...
Only thing I would like is the wasted spark direct fire ignition coil pack.
Its capable of supproting electronic injectors... should be Ok.
Need the mapping software, but someone like Geoff has this.
Dimsport may well have this also.
Unichip may be an easier way of getting the same end result tho.
Needs more investigation.

Glued together?
What ecu model is it?
Hopefully reflashable (IF) there is code to do this.
VW in thier wisdom decided that the emissions of the Lupo GTI were already slightly high. So to stop tuners making the car faster and thus worsening the emission levels, they basically insert the ecu pcb into its box and fill the rest with glue!
So if you try to open the box, there is considerable damage to the pcb by many components being ripped off.
I dont know what model the ecu is but its only possible to remap by wire or get a custom ecu. Thats why ive asked Kev at Revo and Jabbasport if they do remapping for the GTi, unfortunately its a no.
When I get the car I want to keep it normally aspirated but make it as fast as physically possible without spending silly money.
