Fast Eddie's 02 T/A vert.

Is it because of the compression of our motors.

Please educate me,why would higher octane not be good?

What is it that makes it so much different from the old school motors.

Thanks in advance.

not 100% sure but I think it has to do with a few things... 1 the position of the spark plug, also the fact the blocks are aluminum (quicker heat dissipation)... i'm sure there are other factors as well...

Generally it's best to run a car on the lowest octane you can before you get detonation... octane is basically a rating that determines the restistance to combustion... so if a car runs fine on 90 octane and no detonation, running on 100 octane can hurt performance because it's harder to ignite the mixture... however running on too low of an octane can cause the mixture to ignite sooner than desired and thus pre-ignition (so the knock sensors will remove timing in an attempt to stop this and if it sees it enough it'll go to the Low octane tables in the PCM which basically decreases timing significantly)

we have 91 in cali, thats the highest we can get localy

Cylinder head design is probably the leading reason why we can run more compression, less timing and make more power on worse gas. Its also why we get better mileage.

LS1 cylinder heads were probably some of the first american V8's to get the benefit of computer physics modelling. It saves a lot of money in R&D because they could "run" the engine in the computer instead of building costly prototypes.

hey fast eddie, do you have any pics of your car? i have been looking to see a car with the sportlines on it vs the prokit, im jugeling wich one to get.
