Thread: Running your car without a s/c belt?

The fueling is controlled by the Maf sensor and how much air is flowed thru it. You will be running rich when the car enters into fuel enrichment(30 percent throttle-WOT) but other then the car being balls slow it woulnt really cause any issues other then maybe contributing to cat failure and maybe fouling a plugs. Your car will be considerably slower then say a GT because of the lower timing and fatter fueling and lower compression

Bogging when entering boost sounds like you have some Knock retard issues or a misfire. Whats your mods

its very slow without belt... i drove without one for 3 days. how many miles on the car?

Yes it is slow, you would be lucky to make 180hp on it. BBV will not cause a sputter or hesitation entering boost

I just told you how in the first post

To recap, The maf controls fueling by metering the air. Less Air = less fuel. You're still commanding a 11.5ish afr so it will still go rich when you go 30-100 percent throttle.

didnt read anything up until here, got a cat on the car? is it clogged?

Exactly what I was thinking when I read this. I don't think it's your BBV. The BBV uses vacuum to close a butterfly valve that allows boost to blow back up into the front of the supercharger before the rotors. When cruising, this valve is open making no boost since the extra pressure created by the spinning rotors is released back into the low pressure side of the supercharger. When you give it more gas, vacuum will cause this valve to close forcing the pressure from the spinning rotors into the motor giving you more power. Air that goes in, has to come out. If your cat is clogging up, that extra air when under boost will have a hard time getting through it. If the belt is off, the rotors are not spinning and forcing more air into the motor. Not as much air is trying to get through the clogged cat so it won't choke itself as bad. I would start at the cat to try and find the source of your problem.

this is why i asked how many miles on his car... but he didnt answer me.
