Hello TB community, sorry my first post here isnt a positive one, but I'm having some trouble with my alky kit and am hoping someone here has some ideas.
I have an 89TTA, and normally I run 22lbs of boost with the alky knob set around 5 with no problem running turbo tweaks alky chip. Now, though, I get a lot of audiable knock when i try this. I've tracked the problem down to Razors alky kit (which has been doing wonders up till now).
Normally, if I set the knob to 4 or higher and hold the test button, the engine will stumble and die. Now, even with the knob maxxed out, the engine runs smooth, no stumble at all. The activation light will still glow red, and with the car off I can hear the pump. I can hear it get louder as I turn the knob from 1 all the way to 8. It still will not stumble the engine at idle though.
I thought it could be clogged somewhere, and just read a post here stating that if the light transitions from red to green as the boost rises, that means you have pressure. So, I went out and tried it with the boost at a more conservative 19lbs. I rolled into full throttle with the alky knob set to 8. The activation light turned red and transitioned to green and I got no knock. However at 8 I should have been drowning the engine, but it didnt stumble one bit like it would when I would set the knob too high in the past.
I then tried turning the knob to 5, around where i normally keep it, and rolled into full throttle. I got audiable knock and had to back off. I then put the knob back to 8 and tried again, but this time I got strong audiable knock and had to back off. I kept an eye on the activation light and tried again. it seemed to barely flicker to life as the boost rose, and I could hear pinging under the hood again so again I stopped.
It seems to be performing erratically. Any ideas on what the culprit might be? Failing pump maybe?
