Pre-V-Power, optimax, Ultimax etc?
 

Before all these performance fuels were readily available on the market what did people do with performance cars and jap imports?

I cant believe everybody used octane boost all the time.

If you're as old as me then it was 5 star:)

I remember my dad using 5 star :D

They did nothing, but they wondered why the cars blew-up! :D

Octane booster :thumb:

are there any old scoobys on the road still? ;)

Agreed :thumb:

Nitrous Formula for me

Except UK market cars :)


It was all those crappy JDM grey imports that blew up :lol1:;)

Quite! :)

I don't think I could buy one unless I had some kind of proof that a) the owner had always used OB b) It had been properly remapped for UK fuel straight away!

I use the higher grade fuel all the time on my 03 sti type uk, but i still put the booster in on every 3rd full tank.
Doesn't seem any better though !!!!!!

what about countries that have even crapper fuel?

What octane rating to the US have?

They use water with drops of oil in it!! :lol: :lol: :lol:

That fuel must be great to use on high spec cars! NOT

They have really sucky RON, that is one of the reasons why most of their cars (with very few exceptions) take 6 weeks to get from 0 to 60, and just generally suck.

Actually....the US RON rating is calculated in a different way to ours, so a low figure of say 90 RON might be similar to our super unleaded.

How so? Thought it was more or less calculated like we do it over here.

another pslewis clone ;)

5 star.they were a goup in the eighties want they:thumb:

You don't need to use OB on a UK STi. It was just the latter classic STis that were set up to run on 100 RON that weren't happy on SUL without OB over here.

Your UK STi will only advance ignition so far; any increses in octane above and beyond that will have no effect on performance. If you're already using 99 octane, that will be more than sufficient (unless the car has been re-mapped for higher).

I'd save your money on the OB. Maybe a splash on hot days, or if you plan to use the car on track for extra resistance against DET, but that's about it.

I'm a far cry from that old man...I'm a "real" engineer, he just has one of those mickey mouse degrees bought cheap from one of them dodgy American diploma sites. ;)

UK cars are mapped for UK fuel :D So 95RON perfectly safe in a standard non-ppp UK car.

There was a reason why the UK model classic shape Imprezas were detuned to 208/215ps instead of (later) JDM's 280ps ;)

Cheers for that i will pass on the booster, it has not had anything done as yet he is still standard.
Thanx again

:lol1: thanks for putting me straight shark man!ive got no problem being put straight be somebody who has some cred:lol1:

In the days before super unleaded people simply didn't buy Japanese imports. They only became popular in the late 90's because super was available and so businesses sprang up to handle the importing of Jap motors. Previously it had all been personal imports - handled personally by the buyer - and these were a rare sight on our roads.

Why do you do this? every 3rd tank?

And its UK spec car :cuckoo:
