just to be on the safe side, see if you can get a tune for that race gas. you might be all right using it, but it still might cause some problems. even if it doesn't, a high octane tune will be able to make better use of the gas, anyways.
Well, it really depends on the fuel... All race fuel is not the same. The big problem with airplane avgas is that it is designed to burn best at a high altitude, and we don't drive up there... Quite often fuel will allow your car to run better, a bit crisper perhaps, but without a specific tune for it you are only going to achieve minimal results for the amount of money you are spending, with a dedicated tune you can get more, but you really only need it if the engine is built up for it ( turbo High CR etc. )
If it is unleaded it will not hurt your car and if it is leaded one or two tanks aren't going to kill your cat, but I believe it will over time, not sure that is a fact though.
octane rating simply is the resistance to detonation. if you are tuned for 93 octane and you put in some street blaze 101 or something, your just wasting your money. it does not make more power, it lets your engine make more power because it can be tuned more agressively. some may say that they "felt a difference" but thats bullshit all it might do is smooth out your idle on a hot day. so unless you are having detonation problems or are tuned for 110, dont waste your money.
There's more than just tuning...you can't "tune" a low compression N/A engine like the Zetec to run 93 octane. Now if you raise compression or add FI running 91 or 93 becomes necessary, but its not the gas that adds the power, the gas is letting you change your configuration to make more power without destroying your internals in the process.
I'm having some stalling with my car, so my tuner (Tom) told me to adjust base idle. I figured maybe I should get a new TB anyway, it seems to be sticking a bit, and it's a 15 year old part anyway.
I was considering getting the C-F-M 65mm TB.
Problem is there are two options...
I bought a MF 49231 converter to replace my factory unit and staged it up yesterday. The upper flange fit good, the support tabs were on spot, but the rear or lower flange was about an 1" too high jamming up into the oil pan while changing the flange angle as well, and not clearing the engine...
Hello everyone. I am a newbie to this site. But no newbie to turning wrenches. I just recently purchased an 02 focus SVT with broken intake camshaft for a price I couldnt pass up.
Camshaft is stamped with FCM1A in my car.
I ordered a camshaft from a member in a focus svt group this week and the...
So the car on my 2000 zx3 was bad so I ordered a new "direct fit" Bosal cat from rock auto. There are a couple fitment issues, but the biggest issue is the fact that the downstream O2 sensor port is IN the cat between the two substrate layers instead of in the pipe downstream of the cat.
