would this stuff be worth using on track days or thunder road days
to protrct the engine ??

Is the engine capable of advancing the ignition the required amount to take advantage of this magic juice?
Do you already use super unleaded?
yes it is, yes he probably does, will he see any benifit from using snake oil? NoDo you already use super unleaded?
thats a 
then to both ..
but would it help protect the engine under hard use ?

Ive got some octane booster but ive never used it. Cant remember the make, i know a few people with scoobys, evos and slylines that like it, but like i said i have never tried it so i cant comment
prob the jap inport boys. A lot of the jap cars never had knock sensors, soon as the imports came over and ran on lesser fuel the engines blew up. The uk cars were detuned or given knock sensors to overcome thisstigmundfreud said:

Plus magazines etc push such products...and if it says to use it in a magazine or teh internet...it is absolutely essential !!
I am not arguing a point with you Steve and having never owned one of the Impreza imports it is only based on my very good friends experience (and subsequently reading other posts) of engine failure which was suspected to be caused by nock and that the specific cars did not run sensors.
Just because a car has a knock sensor, doesnt make it indestructable from improper tuning or less than kind owners.
Nearly every modern car runs a knock sensor. Some more than one. There is nothing to argue on the matter.
People often like to blame all sorts for engine failures....mostly its the two things outlined above.
Although it is true that some Jap Imports are tuned quite close to the edge in terms of safety, so poor quality fuel combined with aggressive drivers or people just messing, can lead to engine problems on these cars.
Tha majority are perfectly fine though if using good quality fuel.
Those that arent deemed safe, need mapped to suit whatever fuel the owner wants to use. Knock sensors on any engine only have limited scope for control, for a variety of reasons.
And your LSx engine is no different. That's why there are two ignition maps within the ecu.. If knock control was at a level that you and others think it is....no engine would ever fail due to knock. Sadly it isnt there yet.

?? I was just countering the comment you made about all jap cars having the sensors. I know they are not the cure all but there are quite a few on here running mafless tunes which generally means single spark maps unless using custom o/s - the question for those with SD tunes need to be asking their tuner is do they have dual spark maps as when the maf is removed (detected as failed) the car only runs off the base spark table
or dont run. Theres far more to worry about at those speeds than a bit of octane boost007 VXR said:
still would like to know, would this stuff , for the sake of just £12.oo help on a day like thunder road , protect the engine in sum way ??
It certainly won't do Any harm. But strictly speaking, it won't be needed if the engine is tuned safely anyway. But for sake of a few quid that little extra peace of mind would do No harm. As to which such product you add, that's a different matter. A couple of very fast pump gas guys here always reccommend me "power pour" although I've never tried it yet.

I have seen many blown engines that detonation has got the better of even with knock sensors.
