Methanol or Octane Booster?
I know they are different but if you had to go for one or other which would it be?
Methanol would win hands down on the price issue as it is essentially free (being more or less the cost of the petrol it replaces and a bottle of OB is about £3 to replace <£1 of fuel) but power and drivability-wise I would be interested to hear people's opinions.

Only takes me around 30 seconds to chuck 5L of methanol in at the petrol station - not a lot of messing around for a big hike in power and torque over pure V-Power. Hardly ever get any odd looks either - most people probably assume you've just run out of fuel and are topping up from a gerry can

Lovely wide torque band What turbo is that JD?
Banny - methanol allows you to run more ignition timing under full boost, especially at the top end. JD's torque curve is much wider and holds up better than would otherwise be expected - it normally falls off as revs reach top end. Having 360+lb/ft of torque over such a wide rev range would make for a blisteringly quick car

the boost is only at 1.5bar on a GT30 hybrid from Alan Jeffery - Engine Tuner and is designed to run on a 2.5 (future plans) but works well on the standard internals of my STI.

My question remains unanswered - though thank-you for on-topic replies so far.
Are we saying that methanol allows more fuel to be burned at higher revs as it burns colder so you can run more boost? If that is the case than good, but will OB allow early timing throughout the rev range and hence have benefit at all revs?
