General Buick Tech / Re: Powermaster pedal vs vacuum brake pedal

« on: June 23 2013, 12:42:31 AM »

I converted my car to vacuum quite a while ago and remember modifying the powermaster pedal to get it to work. The pivot point for the vacuum is roughly 1/2" or so higher than the powermaster, so you have a good memory

I had my morels at .045" and they still made some noise. I have .060" preload on them now and they are pretty quiet. My car pulls hard and has plenty of vacuum at idle.

I installed a tubular f body front bar on my car. Half the weight and the car is definitely more stable. I picked mine up for $35 used locally

I could not imagine driving my car without a scan tool. I look at the scanmaster more than I do the road! Maybe some of these people running around without scan tools are made of money!!!! I know I can't afford to drive without one

I would take the old hoses to the parts house to match the sizes. I beleive that there are a few diffent sizes of vacuum hoses on my car

General Buick Tech / Re: Timing

« on: January 07 2012, 01:00:15 AM »

I have bought a few different TT alky chips and they were always 23/21 for timing. I just bought his SD chip for alky and 20/18 was written on it. I inquired and Eric said exactly what Steve said : program it to where I want it. I have read that Steve does like lower timing and higher boost so that's what I have always done and my results have always been great. I  run street tires and always stick to 21/19 with pump gas and alky. It would probably help to drop the timing more in 1/2, but I kind of like the fun factor on the street.

I have read that to check the base timing you need to jump the a and b teminals on the aldl connector to get the engine in diagnostic mode. With a timing light(if everything is correct), it should be hitting on the 15degree mark on the inside of the timing tab at idle

The rings are just pressed on and I have read that they can slip with age. Don't think that its too common though. I think that mine was never put on right to begin with. The guy I got this new shortblock from only uses Fast and XFI to control his engines so the ring is not so much of problem when tuning

I had a wideband in the previous engine and NEVER had any kr with 10.8 afrs. I am using 91/alky. With the new engine,(different balancer) I get knock at all rpms and not just at the shift points. I always thought it was false. I have checked everything under the sun for false knock. The knock comes on fast and even with gently rolling into the throttle. My reluctor ring looks off in comparison to my old stocker. I did pull the ring off and pressed it back on in the correct position(I hope) Just wanted to get the base timing verified so I could check that off my list in solving this problem. The car ran like it was supposed to when I dissabled the knock sensor. There was no indication on the plugs with any real detonation though. I'm in the process of putting the engine back together after something went through the #6 rod bearing. I have been battling this for quite some time. It has been frustrating to say the least. I remember the good old days running a stock longblock, beating the crap out of it and the only thing I had to do was change the oil!

Thanks for the welcome. I have been having some kr issues since my new rebuild and have checked everything for false knock. I pulled a lot of timing and added a bunch of fuel to see if the kr would dissapear. It did not. I have read that sometimes the reluctor ring could be off and the timing could be either advanced or retarded depending which way the ring is off. If it is advanced in my case, my engine would be seeing the timing that is programmed in the chip plus the extra timing with the ring being off. That wouldn't be too good. I have an idea, by doing research, on how to verify the base timing but wanted some more feedback. Thanks for your reply

What is the best way to verify timing on a gn? I think my reluctor ring on the balancer is off and want to check the actual timing, Thanks
