ORIGINAL: mustang_montana hows the power in your s281?
the power is great. it dynoed at 290 stock and i added a BBK 75mm TB and got 6.5 rwhp. -it was humid the day i dynod anyway. ive actually got the series II blower in my car, i know that the series I and series II are both eaton roots models. by the way, 296.5 rwhp is a blessing with my setup.
going on with a few months: sc pully, plugs, boots, headers, catback, x pipe and gears
going on later in the future is: heads and/or cams.
im hoping to get a solid grip on the 400 rwhp mark.

you should really have to "downshift" like they are talking about during normal street driving. if you are coming to a stop light just put it in neutral and slow down and if it happens to turn green before you stop, pick the right gear (experience will help you decide which one) give the throttle a tap to raise the rpms (sometimes you may not have to do this depending on what speed you are going) and let out the clutch. after practice and experience you will learn what speeds go with wich gears at certain rpms and if you need to blip the throttle when shifting into a low gear.

i usually shift at 2500 rpms. just fyi
Addition to this: Don't hold the clutch in instead of putting it in neutral unless you want to be replacing your throwout bearing relatively soon. Just put it in neutral and keep your foot over the clutch instead of keeping it pressed down. I have heard that in some states it is illegal to be out of gear when coming up to a stop light but this seems very retarded to me, plus, how is the cop who is going to pull you over for it going to be able to tell?
I tried the heel toe business, and i didnt have enough room to actually use my heel, but I got it down by using the area of my foot under my toes on both pedals and just kind of rocked it on the edge of the brake pedal to keep the rpm up, it is very smooth. Its almost like driving with the choke on.

wtf is the point of downshifting? Its just waisting more gas, Just put it into neutral and use the brakes.
i guess what u descibed could be considered incorrect. The engine is supposed to help slow the car down, downshifting or not. You'd want to leave it in gear for as long as possible and then push in the clutch obviously before it stalls while using the brake...

yea, according to the law, your always supposed to be in gear, never coasting. but down shifting doesnt really waste gas, your just using the compression of the engine to slow you down, the only gas waisted is the blip of the trottle, if you even blip it.
also some smarta$$es will slow down by downshifting and using the gears instead of the break. very stupid, it is hard on the gears and you tranny wont last long
for the people saying that downshifting is dumb/pointless, umm why do race car drivers do it? why do truck drivers do it, oh yeah if you go to get a job driving a truck and you push the clutch in and put it in neutral and just use the brake, well guess what your not getting the job, if you cant downshift then you cant drive so if i was you and i drove a stick i would learn, now im going to go try heel toe braking, i have done it before but i need to work on it lol

soooo i guess im a smartass, i dont see anything wrong with downshifting at all, just blip the gas to match up the rpms. It's no worse then hard acceration, when you get on the gas you are putting stress on the gears, correct???????

[double clutching is] not necessary because of lighter transmissions and synchronizers
Lets see... you shouldnt downshift because it's hard on your synchros, but you dont need to double clutch because the synchros are new and improved.
Kinda contradictory, eh?
Not saying anyone's wrong, i just thought it was cute.
