Octane
Turbo Mini Forums

Has anyone used this in their Turbo engine?

http://www.tetraboost.com

Might be just the ticket.

Group buy might be an idea

i was told leaded fuel was made completely differently to unleaded and that the two dont mix.

i dont know how true this is but if true then any addative could only make unleaded into a similar octane as leaded and not turn it into leaded as the advert says

personaly i use shell V power and a lead replacement addative. (i'm not trying to advertise shell!!)

if thats not strong enough, you could try some 118 ron race fuel but its not cheap at around £4 per ltr

i know a lot of people who use tetraboost in their fuel, reports from others seem to suggest that it works very well at both increasing the octane and reducing valve seat wear. I certainly plan to use it in my mini with my new engine, the only problem i see is that it can/may/will duff up the oxygen sensors over time.

I've seen the future and tbh its Pie

Interesting, might have to read up a bit more on it as I am of a similar train of thought to Turbo Shed. Also if it provides an actual lead suppliment is it actually something we should be running, from a moral and enviromental point of view that is.

Every day is a school day ...........

How fast and how expensive ...... the same question...

i run this stuff on certain days

it does what it says on the wesite, its not a gimick!

very pricey thought

better to invest in megajolt and some cheaper valve seat addative

having said that if your after the ultimate boosted chav scoobie,
mitsi evo killing mini then this is the stuff for sure.

I reckon it's brilliant. If you consider the amount of gas in the atmosphere and then consider the amount of TEL you use and the actual amount of lead in that, it amounts to fuck all. It's another thing the yoghurt weavers banned.

You have to consider "lead response" in your calculations, if you want the highest octane fuel, you don't start with 97 or 98 unleaded, the aromatics (some cyclic hydrocabons) kill the lead response. 95 fuel will respond a lot better. The best amount you can use IIRC is 4cc/L with aviation alkylate (petrol with no aromatics in it) I've heard about 2cc/L is good with 95 fuel. If you can get some, adding another 1cc/L of methyl aniline adds a load of octane boost HOWEVER you really don't want to breathe that in or get any on your hands.

Proper lead rules. Tetraboost is a bit expensive though but buying bulk pays back a bit.

I posted a link to the NE Company who make TEL (only company in the world who make it) I still haven't heard from them GRRR! Buying it in bulk from them may be an idea.

Tinkering with your fuel is as valid a method of producing a better crop of bananas as intercooler size

Bugger off, I'm getting there.

The reason for the initial post was that, being new here and reading through all the posts I found no mention of Tetraboost which I found quite suprising.
This stuff really does what it says on the can and I am sure some of the more aggresive turbo conversions would be certain to benefit and some lower boost set ups should run better and safer.
Agreed it will damage a wide band o2 sensor over time but if it's used on a roadgoing car just remove the sensor after set up and bung the hole and it will last a good amount of time. If its for a competition car and used for datalogging treat the sensor as a consumable item, they can be had for peanuts from scrapyards if cost is an issue.
I have heard, (ie no definite personal experience of), that if you put a shield in the exhaust pipe to stop the exhaust flow impacting directly on to the o2 sensor the life of the sensor can be increased considerably.
Agree with Hedgemonkey entirely other than the 95/98 octane base fuel argument. He is probably dead right but when I have used it I followed the instructions to use 98 and it worked well.
I have a sneaky feeling that the manufacturing company of the TEL will not respond as they seem to prefer supplying small countries with their product rather than small specialist interest groups like us.
I know it's a dear do to do on your own but if a few get together the cost is not so bad.
I have absolutly no connection with the company supplying Tetraboost, just trying to pass the word on in case some of you had missed it.
If the moral/environmental issues bother you should you even be driving a Mini let alone fitting a turbo and all the other bits you want rather than need!

I'm a big one for tetra ethyl lead, it would be interesting for someone with a dyno and variable boost/ignition car to play with with different fuels to see what 95 and 98 mixes with TEL run the best. What you could do is just get 4cc TEL 2cc MA and whack the thing just short of detonation.

I fully endorse this stuff as much as I endorse my 14mm rear anti roll bar which is lots.

Bugger off, I'm getting there.

Hedgemonkey. Where did you get all your info on the additives? Perhaps you could do a post explaining it all in laymans terms
"4cc Tel 2ccMA"?????????????
WTF is MA and what does it do?

I am convinced the difference between good and excellent is in the detail. Small things add up and make the difference, ie a few pence / litre on TEL, gearbox splash plate, a few pence of Ali sheet, electric water pump (DIY) a few quid, If you believe what you read they are worth 3 BHP each! That's 9 BHP for not a lot. On a high spec engine it would cost a fortune with an engine builder to get the same.

Methyl Aniline is basically a chemical which helps tetraethyl lead do it's thing. It seeps through yor skin and plays snooker with your chromosomes which isn't a good thing. It also makes you sterile for a bit if you smell too much of it. It's an octane booster which I gather works better in the presence of TEL. Perhaps it only comes into it's own with very high octane requirements.

Anyway, there is all sorts of stuff you can whack in your fuel tank and makes it better, one of the best is dicyclopentadiene with a MON of 172. I think it is the highest octane stuff you can get and good news for you lot, it's quite an easy chemical to come by.

I used to mess around with chemicals and now I teach other people how to. :)

I'll have a look in my chem supplier books at school. I just nick it from the lab

Bugger off, I'm getting there.

That will be great, will you post the info here or PM it? If you are going to PM it please include me.
Following on from the above discussion but still related. Has anyone given any thought to E85 biofuel,It has some advantages over normal fuel if your engine is set up for it and has been used with some success in the BTCC
Apparently it's only available in two areas of the UK at present but during this year should become more widespread.

I know alot of people in the r5 turbo world are using aldon additive dont know much about it myself though!!
