Tesco 99 versus Vpower

[Ross]

Duncan.. for you info we used to load test my engines. buy this i mean long periods at WOT with added resistance from brakes and long slopes.

Quality :?

I ran a digital egt that logged.

My god, is there such a device :?: :lol:

I was taught by a guy in the USA who is a tuning god. I also paid for this experiance. I was taught all about meth and nitro by the people that mix and tune top fuel drag cars.

Those that have followed my methods have all gained :roll:

Care to share your findings with Nitromethane?

[Bladerider]

On occasions,

I have been known to "log"



And on a slightly more helpful note, or perhaps not as the case may be, here is some light reading that might be of interest to our budding chemists.......

...........I will be asking questions later !!!

I might even ask Mycroft of he wants to come and join our happy little community, although these communities are seldom happy or little after he has joined, but some of us still love him despite this !!

Interesting thread that Bladey.... only up to page 9 though

I do find it odd though as he is talking about octane boosters 'fooling' knock sensors by slowing down the flame front to stop det rather than raising octane. Isnt that what the definition of octane is? ie the resistence to det against a base mixture which has a value of 100 octane.

That's a great thread Bladey. Cheers

AFAIK there are three different methods to calculate Octane numbers: MON, RON, & PON.

One of these (Think its RON) used a test engine with variable compression & timing to give the fuel a value for knock resistance.

If NF etc is resisting knock it is effectively raising the Octane, not fooling the knock sensor? As far as I understand their is either knock or no knock!! How you suppress it is irrelevant but would reflect in the Octane rating of the fuel?

Loving Pat the Map's work on there - why use two words when fifty three will do the job perfectly

Invite him along James - his contribution of facts and willingness to share his findings would be appreciated by almost everyone here I am sure :thumb:

I, for one, enjoy a healthy debate and where people can add their own findings rather than hearsay it will benefit the whole community.

The whole ethos of this place is a common enjoyment of our vehicles and if through exploring and understanding how they work and what makes them work better helps to get better results, better performance, lower track times, lower strip times or better drift angles then bloody superb in my eyes.

I know that the complex nature of some of these threads is not what some people can digest or want to digest (including myself at times) and others are completely turned off by it but it will and does make it more important to have a place where these matters can be discussed openly and freely using real information as the backdrop for assessing whether it is something that could benefit the reader. I have learned a huge amount about my car through reading these types of threads and have a huge amount to go before understanding everything I think I need to know (if that can ever happen)

As co-founder of the site with Stu, I would rather that the source of the information was BigPower.co.uk and as such would like to encourage more of the same depth of contribution/discussion be it fuel burn characteristics, ignition advance, revolutionary ECU reworking, adaptation threads and projects such as those shown by Pablo and Bart and complete rebuilds. As we have seen and will continue to see, modification to improve performance isnt soley marque specific - there is so much cross-over of ideas. Content is king and everyone can play a part in that

edit to say: thanks Bladey for taking up half my morning reading all 26 pages of that :lol:

Last night surfing the net i read up a few interesting bits of info on Toluene and all in all it ranks right up there with Nuclear waste :lol:

It's highly toxic, lousy for the environment and clearly extremely hazardous to humans with extended usage/handling....

but all that aside it's top rocket fuel for your car so what the hell...

I'm not one for over thinking a problem so Tescos 99 gave higher recorded knock on the power fc than V power and the car REALLY didnt like running nitrous with Tesco 99 so i only use V power although i have found that variable of late.

I also use octane booster , it allows me to run more power for less det, apart from being able to hear high det on my car pretty easily my power fc records it, at the same nitrous level without octane booster the car records 60 knock, with octane booster it doesnt exceed 20. In normal use ie no nos the car can spike to 45 knock, with octane boost it rarely goes as high as 13 or 14.

I only found the stuff by accident and was told by one of my old drag racing contacts that it was worth a try so i now buy it by the crate the engine seems to burn cleaner as well , it used to start to run a little rough when in traffic like the plugs were fouling , it no longer does that at all

Its called Lucas Octane Booster , the active ingredient is MMT http://en.wikipedia.org/wiki/Methylcycl ... ricarbonyl with a few other things added , i have tried other products and they had no apprecible reduction in knock recordings

I feel that methanol and water injection on road cars is a waste of time and only needed if there is no other option , ive still got plenty of options for det control open to me and octane booster is a valid one and a really cheap and easy one.

That looks interesting - have you got a good supplier for it Rich?
