Hi Paul,

I run SUL with Millers Octane boost.(96uk). engine smoother, maybe a bit more power, not really THAT noticeable.

But MPG well up used to get 200 miles to 45 litres, now get aroun 230 (15% UP)

Cheers

Rich

Question

Hey Rich

I run my 98 Type R on SUL....wot is the rating of it as normal UL is 95.

I'm told I need to be on around 100 to run with the equivalent jap fuel...do I need the octane boost too. If so is Millers the best buy?

Cheers mate

Tim

Tim,

Normal UK SUL is 97 RON. Although it used to be 98 RON and some places still sell it, but they are few and far between. Leicester Forest Services on the M1 is one.

Octane boost should definately help yours run better. I think there are better ones about (I've not tried them) but Millers is easy to get and cheap. Works for me!

Rich

Hi Paul

Silkolene pro-boost gives a proveable (ie on a dyno 4 Bhp on a UK car)

Probably more importantly brings peak torque down to just 1500 rpm and then an almost totally flat torque curve

I guess you could call that a benefit!!

Cheers

Cool

Octane Booster brings the peak torque down to 1500rpm without any mapping?

How the hell does it do that then??

I am with craig!

hi craig

The jecs operates on lambda control in cruise but not at wide open throttle to my knowledge??

When looking for peak figures, I believe wot is used, in which case the jecs operates a fixed map. Without a remap, can't see how the peak figures would be altered!

if the octane boost lets you use more advance then you'll get more power.

Detonation is (in theory) more likely at full throttle, low engine speeds (because there's less turbulence in the charge within the chamber).

so octane booster would tend to bring peak torque down.

But from about 4k to 1500k?

214lb ft at 1500k - what does Silkolene do - make it a WRC engine?

Gentlemen.....

If any of you doubting thomases have a fax number i would be delighted to fax you the before and after torque and bhp curves for one of our customers almost standard UK car.

The sole mods are downpipe and backbox on both graphs....

Nick was quite correct with his technical explanation... Like i always say.. you are all more than welcome to come and try if you are dubious.

Our demo is a standard UK with the right exhaust bits and permanently running on Pro Boost.... Its a tad brisk.

I have to be honest, when we were given all this spiel by Silkolene our response was also "yeah, right". but it does make you realise how octane sensitive Subaru's very basic ECU mapping is really, particularly on Jap cars which SHOULD NOT be run on anything less than 100 octane anyway.

If you think those Subaru results sound silly, you should see what happens when we add it to a Saab 9-5 with a 32 bit three dimensional processing map. These fellas can really "read" the increased fuel quality and whack everything to maximum... i'm not going to upset you by telling you what happens to the BHP and torque. Needless to say, don't race them on the motorway.. unless you have an STi, P1 or 22b!

My graph is sitting here, now where's yer fax numbers?

Cheers

Paul, TSL Motorsport

All I can say, is if Silkolene does actually do this to the power/torque, I can't wait to see what NF will do.

Hi Harj

I will try to take a digicam pic of these graphs and post them up for you all to see at some point today.

Have u got a fax, mate?... i will gladly send it to u in the mean time.

The figures were obtained at Well Lane Turbo Centre's rolling road by one of our customers. Obviously I cannot vouch for the accuracy of their equipment as they are an outside supplier, but I am led to believe this is a most reputable set-up.

What i forgot to mention is also how the BHP curve isn't!..... it's almost totally linear/proportional whatever. As I say, you are all welcome to come and try our practically standard (mechanically) car and see for yourself.

One last word.. if you get some, don't sniff it ( in a curious way, obviously!!).... I did and couldn't see straight for about five minutes. i have no idea what's in it, but I think it's pretty strong.. therefore sadly, we can't post it to you.

even better, i will try to get our web guy to post a page dedicated to this on our site.

Sorry to keep banging on about this stuff, but there are very few additives that we have ever tried with regard to fuelling and lubrication that conform to the Ronseal standard....

drop us a line

Trouser - I'll email you my fax #

would be good to see the graphs....

used to use Pro Boost whenever I couldn't get SUL - didn't often use it with SUL.

Howe many RON points does it give you, cos the blurb on the tin isn't very specific. or are you talking about something other than Pro Boost?

Paul,

How much is this Silkolene stuff in bulk (say 20 bottles). Can you fax me the graph? I'll mail you with my fax no.

Cheers

Paul all fair with your reply but how does Octane Booster give you max torque when the turbo hasn't kicked in yet? I am very interested as no other Greasy company has ever made such a claim and the guys i know at Silkolene, never spoke about this when I was enquiring about Engine and Diff oils.

Can you please post the Graph up and explain on where the RR Figures were taken?

Cheers

hi Guys,

According to the figures we have, Pro boost appears to raise octane by roughly four points from 97 to 101.... exactly what you Japsters were designed to run on anyway.

Thanks to people who have been good enough to mail fax numbers.. watch out this arvo!

We would be happy to do bulk deals for people. Please remember, we can't post this stuff...it's totally illegal to send by normal carriage Try one first to see if you agree! Not many people end up buying just one!

The beauty of this stuff is, it's selective horsepower. You only pay for them when you want them.. ie. trackday and thrashing for UK cars... always for Jap.

Faxes coming throoooooo!

cheers

Trouser

PS. Please note.. continued use of Pro Boost may cause serious erosion of 0-60 times and standing quarters... but i know you all stick to the speed limit anyway

Question

I've a UK turbo + it definitely runs better on SUL. I was thinking of changing to NUL + booster because of the availability / variable price of SUL - how much does this stuff cost & how much fuel will one bottle treat? Will I get the same benefits running NUL + booster as SUL?

Richard

Trouser,

I can't find too much info on this - although I have personal experience.

Can you explain how the booster will make the turbo spool up quicker to bring the torque curve down so much?

Or is the second car actually a BMW 330d?

Fax is 013322 832958 - will be interested to see it.

Craig

What is NF made from?

I met the chap who invented Pro Boost a couple of weeks ago and learnt a lot about the different brands and how they work.

Most use mangenese which forms manganese oxide at the flame front. Effective, but leaves a deposit on the internals and turbo (and sometimes on the back of the car). The deposit is an orange colour.

Pro Boost uses a blend of Methyl Tertiary Butyl Esther and Toluene. The same chemicals are added by petrochem companies to vary the octane ratings and are what is used by Carless to blend WRC "control" fuel (Carless are the WRC fuel supplier).

The contents of Pro Boost are all complex hydrocarbons and no residues or deposits are left. It works, basically, because the molecules are a far more complex structure than Octanes and Heptanes (the main constituants of petrol) and its more difficult for free radicles to break down the molecules and extract the hydrogen and carbon atoms. Hence a more controlled burn rate.

One of the reasons Pro Boost is dearer than other octane enhancers is that it carriers Fuel Duty.

Anyway, I've tried some in my WRX today.

The WRX is different to any previous Impreza in that it runs a high degree of advance and then uses a very sensitive knock sensor to retard this to suit. A classic Pro Boost requirement I thought...

... and WOW what a difference

Knock down from 8-9 degrees to 5-6 degrees with better pull right up the range. It will be interesting to dyno the difference.

Pete,

I could tell you, but I've been sworn to secrecy and would have to kill you if I did

I'm not disputing the fact it works - the better Octane Boosters appear to, to greater or lesser degrees anyway.

What I am disputing, is how Octane Booster can move the peak torqueof a car, some 2500 RPM lower down the range, without any mapping.

Maybe you could explain others comments I've heard about Proboost causing engines to run hot? It was after all, designed for motorcycle use I Believe (whether that makes a difference or not, I don't know)

evening!

Thanks to Pete for his normal eloquent answer.. were you reading that from the silkolene seminar notes? ....

Not being a chemist or engine builder myself ( we have staaaaff for that ). i haven't got a clue why peak torque kicks on so much lower down.

Luckily i was in school the day we did graph reading and momentum and inertia, allowing me to read and feel it all by myself

every car we shove it down seems to drive like it's **** is on fire, but no difference on the old temp guage..hmmm

Good stuff, go on.. try a tin, never mind having a tiger in your tank, this is more like a very large group of upset rhino's

Cheers

I've tried it before.

Made no real noticeable performance gains on SUL - did feel smoother though. But bought it cos I thought it should go in an STi.

Still blew up tho

Are you talking about the std temperature gauge, or a decent aftermarket one?

And wheres my fax?

Any chance of getting this stuff in the states?

We have really poor gas here in Albuquerque, NM. We are at 5200 Feet above sea level, so they can get away with it in non turbo cars, but since the WRX tries to compensate for the altitude by increasing boost, i think it would be nice to have a bit of this.

By the way our best combined octane rating is 91. Its not quite as bad as it sounds as they measure it a bit different, but it is still pretty bad.

To try and make life easy for you all (and obviously blatantly attempt to sell some Pro Boost, we should have a glorious web page devoted to the stuff at the utterly fantastic
