Well the title says it all, my 3rd day home from work so i decided to install my lower mount, well needless to say people arent joking about increased interior vibration. But i dont care.
Heres how the test drive went, start off easy in first, then slam the gas just after the clutch is all the way out.
2500rpms - no boost yet - good traction
3000rpms - very little boost, good traction
3500rpms - more boost, things are moving a lil bit faster now - traction is starting to be sacrificed
4000rpms - 4psi guessing - tires are starting to really get outa control
4500rpms and up -closing in on 5-6psi - and the whole idea of traction has gone out the window.
Its awesome, spins through first gear, spins the crap out of 2nd gear, spins 3rd a lil bit. I think with a clutch upgrade i will be grabbing 4th gear. The lower mount recovered a TON of power.
Yay, im boosted!
Not to mention i think alot of people are kind of wierded out when they hear a loud whine comin up behind them, then a blow off valve, and then look to see a sunfire in their rear view mirror

sounds like its time for better tires
LOL
Heh i think i'd need r comps to get traction, right now im running 224/45/17 Michellin Pilot Sports. They are close to the end so i am thinking about getting some kuhmo's next time around.

Nice dood!! BTW what type of fuel mods came with that kit or did you put on your ecotec??

Kumho's are nice and they don't cost much but i don't suggest getting the Kumho 712's... defiantly would need something higher then them... I have the GM supercharger with a few other things on the engine and at 4.5psi 1st gear the tires spin from like 2000rpm's up to when ever... 2nd spins easy and 3rd i can grip.. only way is to go easy through all of 1st gear and then your 60ft times suck and it hurts your over all 1/4 mile times.
Supercharged 2.4L
No fuel mods on my ECO, RSM reflashes the PCM for you. I believe the stock eco injectors can handle the 6psi im running. Chris had dyno sheets on his RSM kit and he was running around 11 a/f ratio i believe so it should be good.

i'd upgrade the fuel system to be on the safe side, plus you'll probably gain some more power, with a better fuel system, hell get an msd setup and you should definatly get more power. just so you dont risk blowing something up on a hot day or something.

Stock injectors should do just fine. It's still always a good idea to keep an eye on mixture.
MSD....very good idea.
An upper mount will help with teh wheel hop. We do not offer one so far. Sorry. I am working on that. Control arm bushings are a smart choice too.
Will a reflash help if i turbocharged my ecotec instead of getting there supercharge? i heard people running the 00+ reflash on there 2.4's with a turbo wonder if it would help with the ecotecs fuel delivery????

Exactly what he said . . . if you also have a 5 speed tranny some new tranny mounts should really help you out . . .
Upper, Lower, Tranny, C Arm and you should be set... as for the wideband... thats a very good idea as well to make sure you dont lean out or run way too rich . . .
Ive thought of getting the tranny mount but im not sure its worth it have others with 180+ whp noticed a benefit?

You can definetly feel the power when you have the mounts. like a whole new car.

my g/fs 02 eco spd , i had just the motor and lower mount , the car had a droaning vibration noise inside , and once i put the trans mount bushings in , that noise was gone
and the road feel and shifting improved alot also
the feel you got from the lower , and upper , is what you will feel with the trans mounts also
tranny mounts are a great idea.
