Quote from: 460 turbo truck

and i don't see how your saying this is a speed density, there's no mass air flow, or vane meter's on the 2.3 N/A's,

i haven't seen any under drive pullys for the 2.3's maybe you could fill me in ..

No mass air sensor or VAM is what makes it speed density...

Racer walsh sells crank and alternator underdrive pulleys, but the two together cost $95 and really do practically nothing. I didn't even feel any difference on my turbo coupe when I put them on it.

Anyway...well, I suppose if you do all that work you'll get the car up to 100 hp, but it'll still be slower than shiznit, especially with an auto. I think those cars need 150 hp to even be "decent" (i.e. accelerate well enough to merge onto highways and pull hills). You have to remember that this is a near-3000 lb mustang, not a 2000 lb honda.

Oh yeah, and if your tranny was just rebuilt to stock specs, don't be surprised if it does take a dump on you not too long down the road. I'm just speaking based on what I've heard from all the guys with autos over on stangnet and turboford.

i don't get it ....

you tell me that i can't put a cam in my mustang, because it's speed density, how is that so ?! ...

and i'm pretty sure that even if i did have probelm with my tranny..i can get it rebuilt for about 200$,

I take it you are not familiar with the differences between speed density and MAF/VAM systems?

To put it most simply, if you put any cam other than a stock equivalent into a speed density car, it will run like dog doo. It has something to do with the fact that the computer uses some kind of pre-determined tables for everything, so changing the cam throws that all off, computer goes haywire, car won't idle and runs like . Now, on a mass air car you can change cams at will because the computer can compensate for the difference, but in a speed density car it has no way to deal with it (or something like that)

that's what i was asking,

so the car detrmines the values, base on the speed and throttle input to the ECU, as opposed to MAF/VANE setups...where it can tell how much air is coming in....

so N/A motors = bad cam swaps
Boosted motors with vane = good cam swaps

As long as the cam does not have alot of duration or a narrow lobe seperation angle it will be ok in a speed density system.

I would go no bigger then the a234 or a237

when a cam has long duration it kills vaccume and gives the map sensor a signal to richen the mixture wich gives an erratic idle and surging.

the adjustable fpr will help you richen or lean it to some extent.
