Hi. I just wanted to report in that I put a small Sunpro black guage with white letters and a red pointer in my 1993 Oldsmobile Touring Sedan today. As soon as I can get my digital camera to cooperate with my computer again, I will post pictures here. I am reading about 8 lbs. of boost at WOT with everything still stock. I guess that is pretty accurate. I ordered and have in my possession a 2.2 pulley. As soon as I get the pulley puller I ordered, I will change it and report back on my findings. Thank you very much for all the pictures and help to get this hooked up. It looks great and I look forward to sharing the pictures as soon as I can. Happy New Year.

You don't need a special puller. Go to NAPA or Autozone and buy a conventional 3-jaw puller. Our pulleys are keyed, not pressfit like the Series 2, and they're steel, not aluminum (your new pully is aluminum, though).

Default Too much boost? It went Blooey!

I put the 2.2 on and the motor lasted about a year. I have a dead miss and will be removing the engine soon. The dealership said that the center piston on the front side has no compression. I guess the 2.2 pulley was too much. I did get a burning smell when I got on it. It HAD 12 lbs of boost. I'll update you with what I find when we get the motor out and disassemble it. What is the measurement of the stock pulley?

Stock pulley on your car is a 2.55". This is why we tell people to do three things on the Series 1.....

BEFORE pulleying down:
1. Check fuel pressure.
2. Repair exhaust manifold cracks (you have them, trust me)

AFTER pulleying down:
3. Scan for KR on a warm/hot summer day.

KR killed your motor. It could have been prevented. Can I also ask what octane fuel you were running?

I cannot tell a lie. I was in a hurry to fuel up and the station I stopped ats' highest octane was 89 and that is what I used. They are also adding ethynol to their gas also. I usually use nothing less than 92 octane.

What is the best way to check for cracks in the manifolds? Do I need to upgrade to better manifolds? Do I need to downsize my pulley?

What do you think the burning smell was everytime I built up boost? It did not make this smell all the time.

If you don't have a scantool, a fuel pressure gauge, and PERFECT manifolds, go back to the 2.5" pulley.

There is no question or debate. It'* already cost you.

The cracks are VERY hard to see. You need to take the manifolds to a GOOD exhaust shop.

Yup, Pull off your manifolds and througly check for cracks, they are sometimes nearly impossible to see without some type of magnification.

And the burning smell you were smelling was probably either your cat getting extremely hot, or your exhaust manifolds glowing. Was the smell a rotten egg smell or a hot metal smell?

More of a hot metal smell. I can remember the old rotten egg smell produced by old cats twenty years ago and it did not smell like that.

Your manifolds would have been glowing LITERALLY red hot if you'd popped your hood at night after a WOT run.

I gaurantee you have more damage than just the #3 piston. It may have gotten the worst of it, but all of them suffered.
