Ok guys i just got a cutout. First off i felt a tiny bit of improvement using the butt dyno... can't say how much i felt really cause i dont know how much 1 HP feels like! But it diffinatly soudns awesome.

Ok onto the problem, before on my car my RPM's did drop kinda slow (is this normal on the LT1?) But now my RPM's drop even slow! i revved my car to 5000 RPM and then just shutoff the car, it took like 3 or 4 second for the engine to spin down!!! is this normal?

 

ud think it would spin faster do to less restrictive ness? no? Mabey its just louder so it SEEMs that way? u hear more engine noise now

 

oh it spins up just as fast maybe even faster, but spinning down. Thats whats gotten slower....

 

i have a cutout on my 96 Trans Am. i don't seem to have that problem. is yours a manual or auto?

- jay

 

i have a manual.

 

Well, i have no problems with it spinning down, but i would definately recomend AGAINST reving it to 3000 and then shutting it off. Not too good for your motor man

 

oh really? what happens to the motor when u rev and shut it off???

 

yeah what happens. ive got a habit of doing that ever since i heard it was a good idea for rotaries (first car was an rx-7)

 

when u rev it to 5k like u said and shut it off my guess is you would have a bunch of fuel and no spark. With the motor still spinning there could be a chance of all that extra fuel u dumped in there igniting and blowing your exhaust off, thats bout it. Not flaming ya or anything but why would you want to free rev it like that and shut it off anyways??? 5k is alot on a motor with no load on it, that alone is preety hard on a motor.

 

ive had my cut out for a while now and i dont have a probelm with that, mine just backfires alot with it uncapped, now put ya a set of headers on it and see how better it sounds and the louder it can get

 

yea never knew it was bad for the motor, didnt really mean to do it either

I'll be more careful next time!
