    Re: The engine has developed a knock

    She's back together, starts like it should, not hard and slow like it did. Lifter was collapsed 3/8 of an inch. Going to move the iat sensor to the manifold. And add a place to add coolant to the intercooler. I don't know how they got any in there, or if there is any in there, just a nipple to bleed if off... also have to find out why it's only making 5.5 lbs of Boost. Guy working on it tells me it should be making 10+ lbs judging by the pulley sizes. Maybe the 8:1 comp ratio? And then a dyno tune.. she'll be back at the track soon!

    Re: The engine has developed a knock

    I'm only making about 5.5 psi boost and even then that's only at about 6k RPM and above.

    Car description says you're running an underdrive pulley. If that's on the crank, then that could be a reason you're not getting more boost.

    What jackshaft pulley are you running?

    I'm not sure about that pulley, the guy at the shop says the crank pulley is standard size, I don't know what size is considered under drive.

    The guy doing the work said he is going to find out the pulley sizes. I'll know late Monday probably.

    Re: The engine has developed a knock

    IAT has been moved to the intake manifold and a tee has been added to the intercooler line (nearly a gallon of coolant was added, that can't be good). He told me that the Meth wasn't working. We looked a little closer and noticed that the control box was turned off. We turned it on and pushed the test button, the test/working light turned on. He asked me to place my hand by the injector while he pushed the test button to see if I could feel anything, I didn't. Is the test button supposed to spray when pressed? I understand that's all about how it was installed, but what is most common? The kit is Alky. I have the manual and it tells me that it is set to spray at 4lbs of boost. I have seen the test/working light come on when getting on it. I'm assuming it works fine, but am unsure. He tells me it was one of his employees that was working on it, and he wasn't around to ask.

    Re: The engine has developed a knock

    Meth is working, a vacuum line fell off...
    He took it for a spin and told me that it was only running 3lbs of boost and felt weak. That didn't sound right to me. He got back to me later and said that it had belt slip and it was because the guy that put the belt back on routed it wrong, I told him that he is the only one to touch it now lol. He states that it's back up to around 5lbs, but not quite "holy ****" I told him to make it holy **** lol. He is looking into the pulleys on the back of the motor.
