Timing: How much was it hurting me?

Ok, so I just got my car back from the shop. I got a new Timing belt, and tensioner and a water pump on it. As it turns out, my timing belt has jumped a tooth on the belt, ripping a tooth off of it. So how much would timing being off this much hinder the prformance of the car?

dont drive the car around like that. get it fixed as soon as you can. you could jump another tooth or have some serious engine issues as a result.

Yeah, it's all back to normal. In fact, the car sounds different now. The exhaust I mean. It sound slike a different car.

And Caliguy143, read the post, it was replaced. Damn

So back to my original question. How much power was I losing?

But how much. A lot doesn't tell me anything. I'm lookin for a ball park figure here, just roughly how much horsepower. How much does one tooth off effect the performance? Dyno numbers were 155whp, 148wtq, without the test pipe, and with the timing off. About what can I expect now?

One tooth on the cam sprockets is nearly 10 degrees, since it "sliped" the timing is now retarded by nearly 10 degrees. .

This is probably going to reduce torque and power by as much as 15%

The fact that you have a slipping timing belt is a BOMB waiting to go off. . . You do NOT want to play that game. . . I would highly recommend you get it fixed ASAP

I swear nobody reads the post fully before replying. thanks for the reply bryan, now I know what I've gained in having it changed. Yes, read the post, it's already been fixed. I'm just trying to figure out what I lost before this when the timing was off. I dynoed 154whp 148wtq this summer with the mods I have except for the test pipe. I was looking for a good idea of what the car has now. :s6:
