Purpose of the thread was to give members immediate link to the Shell site on V-Power (Shell's web sites can be complex!). Can't help asking em I work with the fuel team at Stanlow. The interesting thing will be to find out who has the best performing fuel Shell, BP or Tesco in a back to back challenge!

They have done a back to back in one of the performance mags, I remember reading it. They have not done it with V-Power, BP and Tesco yet as far as i know - be interesting to see who grabs it and settles best fuel contest!

Defo formulation upgrade to the ad pack. Be interesting to see fuel comparison back to back test and dyno result. Shoot out on fuel would be interesting as now BP and Tesco have joined in the race for best high performance fuel. Shell have repositioned Optimax as V Power and upgraded the product at the same time. Legally they can not claim upgraded performance unless they prove it otherwise they are in big trouble (big loss to their cred if proved wrong and they don't want to upset big red!). The only way to prove it would be some independent tests and dyno work - then we would really know..... you can be sure of Shell!!!!!!!!! sorry just remembered the jingle Out of interest did you know Shell blend specifc fuel for tanks and fighter jets - for the MOD - you wouldn't gamble one of those mega BHP engines me thinks!

There seems to be alot of interest in Shells new improved formula as I work with the Shell Fuels Group at Stanlow where V Power is made, I asked the V Power team if they would give me the Shell Web site reference - here it is..... Clearly they will not provide the secret formula - bit like Coke - however hope it answers a few questions. Great fuel and a mega invesmtment in R&D to pull off - F1 expertise defo transfered into street fuel for us mkae your own minds up ! http://www.shell.com/home/Framework?siteId=uk-en&FC2=/uk-en/tailored/shell_for_motorists/fuels/vpower_p/zzz_lhn.html&FC3=/uk-en/tailored/shell_for_motorists/fuels/vpower_p/introduction.html

As posted it would be wrong to post names of tuners directly and unfair. If you want that story you'll have to get to get in touch directly.[GRIN][/GRIN] I be posting postives very shortly when I pick my car up! br Jonty - roll of tuning honour!

I am sure they get mega grief from some of us![GRIN][/GRIN]

It would be good to post expereinces - however it would be very subjective. If you would to find out more drop me a note with your mobile

I have recently had expereince over the last 6 months of both excellent and poor expertise/customer service. My bill in the last 6months is £20K, essentially complete rebuild of the engine, new clutch etc. It's going to be a great car However wanted to share that many tuners overclaim their expertise massively and are glorrified parts fitters. They do not understand the complexities of high performance supra's and will have you part with your hard earned cash in a nano second:Pling: It is interesting to note that when you search the forum, members have had good and bad expereinces at the same tuner! This makes recommending difficult and it's hard to be objective. (There is no Which Guide to Supra tuning[sAD][/sAD]) I have explored 6 of the forums top tuners first hand so if you want an upto date personal perpestive on the quality of expereince and standard of work get in touch and consider your choice of tuner for your next project extremely carefully. Good news is that there are some excellent highly capable tuners out there who are passionate about the Supra and can turn your dreams into reality - however just make sure you climb into bed with the right partner as you don't want to expereince what I have recently! Perhaps we should have a members top recommended garage and tuner feedback expereince area to help others?? Br Jonty

I had the OS Giken fitted on my T78 and it drives really well. My old one was Exeddy twin plate and rattled alot. However my new one has slight rattle - it's not snatchy though. You can adjust the clutch usually and a bit of wear might help things. I know wot you mean at the lights - now you have them lookin at you:) Hope you get it sorted as its loads of dosh if you don't like it Jonathan

It might need adjusting - so you should check this checked out first before committing to a new clutch. The new type of clutch you buy is important as it depends on the power you are running now or plan to upgrade to. SUggested Paul Whif or J Japanese can sort this for you - try turbo fit in Milton Keynes? Jonathan

Supra Fuel Man - The Shell Inside Story So is Shell 95 the same as any other 95? Although the base fuel i.e 95 Octane unleaded that is taken by each company is coming from the same tank (manufactured to the European specification EN228), the additive package that is injected as it is loaded into the road tanker is specific to each retailer. Shell has mega expereince in additive techology and that is what makes a difference to the "standard" fuel Does this apply to Optimax Optimax is unique in that it is desgned to protect the engine and give benefits in acceleration and responsivness. Optimax is ONLY made at Stanlow refinery in Ellesmere Port and distributed through the UK. Optimax is the only widely avaiable fuel in the UK that is made from a specially developed fuel base Why does super unleaded on the Continent have a higher octane rating - sometimes up to 99 or 100 Ron The rating is a bit misleading becasue the octane number is just one factor in what makes a good fuel. Some countries have a very big appetite for octane - the German market , for example , like to have very high octane fuel. The standard OEM is still to map thier engines to 95 or 98: with modern engine management systems you have very sophisticated knock control systems so even if you have a fual that's not 98 but slightly above or slightly below, the engine should be able to deal with it without any problems and maintain performance Why do fuels perform much better in some cars and not others? How an engine responds to a fuel is down to an enormous number of things. For example , whether a car is turbocharged or not, or whether it ha a particularly fast-burning combustion chamber or not can make a lot of difference. The compression ratio itself can also be a big factor on how a fuel behaves, so some engines have a different appetite for fuel than others. Optimax has specially chemicals within it to help enhance the responsviness of the engine . That has nothing to do with Octane but instead has to do with how the car feels when you squeeze the pedal, not how the car feels when your've flat out on a wide open throttle. It's a specific thing and some cars will react differently to others. Racing fuels F1 Fuel has to contain 99 per cent the same type of compounds as the road car fuel. Shell take refinery streams from all over the world and mix them together, with 1 per cent degree of freedom to create race fuel Tesco and BP producing even higher octanes in limited batches (not widely available yet) However remember Octane is one factor in driving your cars ultimate performance.

I own a T78 and it's a fab car - however it might drive great when you test drive it and 4 weeks later blow something in the engine - mine did! putting it right if this happens will cost more than £2K and you need to be prepared for very high running costs like 200 miles per tank on hi boost settings. Big singles are superb - however go into it eyes wide open and ensure you can fund the fun - good luck

Where did you get it done - havew you the telephone number and approx cost etc cheers Jonty
