im gonna take that junk off and i just wanted to make sure it was that thing under the alternator before i go ripping into it. thanks!

StephenDeli22

No it is more under the ICM, the thing under the alternator is the power steering pump and im pretty sure you dont wanna lose that.

z28trick

hmm....well a gm certified technician told me thats where it was.. lol but what is the icm and where is it

97 LT1formula

its on the driver side of the motor, right next to the opti. 3 bolts and its out if i remember correctly

z28trick

cool...do i need to do anything else to it after i rip it out? and also is there any other crap i dont need like the EGR valve or the AIR? i dont know what the AIR is though

97 LT1formula

I see that you dont have headers? If you dont have headers i would just leave it alone till you get them and take it out at that point. AIR is for emissions purposes.

If you wanna take the pump out you have to take the hoses off that connect to your manifolds and plug those with caps (im not sure on the cap sizes though) your car will also through a code with the pump takin off.

z28trick

i aint worried about the code...the check engine light has been on for 6 months now.. some transmission code? maybe thats why it burned up again...anyway i have the transmission out right now being rebuilt and im waiting to get it back and just trying to find little stuff to do to it to make it faster.

is the smog pump driven by the fan belt?

97 LT1formula

no it is not ran by the belt.

z28trick

does it hurt power? thanks for your help!!

deputydough

it will not make a difference with hp. some weight savings.

z28trick

is there anything else i can do to free up horsepower?

97 LT1formula

nothing thats free, youve already done all free mods it looks like.

deputydough

get rid of the hypertech junk. seems to be the general consesus on this board. search and ye shall find. get a quality tune from madz28. it looks like you have done all the "easy" stuff. now is the time to open the wallet and make changes.

z28trick

yeah im pissed at the fact that i spent $350 on that hypertech programmer and i took my car to the track and ran a 9.3 with the tuning and a 9.0 with the stock tuning!! my r/t was almost the same both times too..but atleast my car doesnt cut out at 117 anymore...itll bury the needle with 155 on the dash

bigger nads than me. have fun
