stroker kit anyone?

yeah, well if it creates a buffer from my engine blowing up then i'll take that. tuning is a wonderful thing. you can find horsepower in many ways you probably wouldn't think of. so i might lose a couple of horsepower. oh well. in the grand scheme of things it'll be worth it.

If I remember correctly, the Odyssey reccomends premium while the Accord does not. And the engine isn't based off the Accord either, it's the MDX/Pilot engine that was new in the Odyssey.

That makes sense then since the Odessey engine had more power output from its V6 than the Accord V6 did anyways. The chassis is based off the Accord in it though, that much I know. But when I had heard about the power fluxuation in it, it was well before the Pilot/MDX had even been made. It's the management of the engine allows it to run on regular unleaded if need be, as knock sensors adjust to the decrease of octain unlike in other vehicles, hence the power loss.

No buffer. All it does is slow the combustion, possibly having some unburnt gas going through your cat.

how in the hell do you SLOW combustion? all it does is make the cylinder fire at a later time. you know...retarding the TIMING.:finger:

Octane is a combustible hydrocarbon. A 100 Octane fuel mix burns the same as 100% octane. A 93 Octane fuel will burn as is 93% of it is octane and the other 7% is other hydrocarbons (heptane??).

Out of all the gasoline mix, octane is the most inert liquid (burns the slowest). That is how you slow combustion.

And to stem any smartass remarks, race fuel is often above 100 (usually around 104 I think). This is because they use a hydrocarbon fuel even more inert than octane, and burns as if 104% of the fuel is octane.

you're still totally off the point. the detonation control retards timing. i'm not even talking about using a different fuel grade. the f-max turbo kit comes with detonation control that retards timing so that the spark doesn't fire prematurely causing an explosion in the combustion chamber before the combustion cycle is complete like its supposed to be. i'm not trying to be a smart ass, but using different gas has nothing to do with what i'm talking about.

Detonation is caused by compression and heat. While retarding the timing can help, all it does is effectively reduce the CR, which negates the effect of your stroker kit. And the effective CR is reduced further when you add the turbo.

This is one case where keeping the factory/aftermarket timing advance and using 91 or 93 octane (depends which you can get) will really help you put out the power.

retarding the timing makes the cylinder fire at a later time. if you want to reduce the compression ratio you have to change the internals of the engine. i may just be stupid as hell, but somethings you're saying just dont sound right. maybe if you've got a 911 you should stay with it.

[911GT2]

I said effectively change the CR, of course it doesn't actually change it.

Retarding the timing makes the spark fire AFTER the cylinder reaches TDC, so it fires when the cylinder is on its way down, or when it's displacing less air.

Get my drift?

[whoneedsvtec]

that sounds better. but it sounded like you were trying to change the CR by changing the ignition timing. i still say that retarding the timing a few degrees to prevent detonation will totally outweigh losing a couple of horsepower when i'm not creating boost. and besides that. f-max uses the MSD boost timing master that only retards timing when at the desired boost level. and it also retards the timing only how much you want it to. so if you feel froggy and you only want to retard it a 1/4 degree for each pound of boost you can. i wouldn't do that personally but you could. if you did that it would almost not be worth even installing the damn thing. so now we're on the same page, but i still dont think it'll cause that much power loss before the turbo spools.
