Day at the Dyno

[88blowngt]

A few friends and I went to the a dynojet new years eve and got some pulls in to see where we were all at. Surprisingly for 200,000+ miles of drag racing, burnouts and abuse on my lil ol' windsor, she put down 234.04 rwhp and 281.20 rwtq for just having boltons, completely stock motor.

Car had a wideband hooked up for free, found out I was running dangerously lean this entire time. 14.5:1 A/F. Added 6 pounds of fuel pressure, brought it into the 13.5:1 area for the second pull and picked up a horse and 2 torque. For the third pull, added another 3-5 pounds and picked up another horse and torque stayed about the same and got her in the 12.5-12-8:1 range. So not only did the numbers surprised me, did a lil bit of tuning, got her safer and picked up a lil power. Great way to spend 75 dollars. :heart:

And not sure if you can see this one, but another angle my friend captured and put on facebook.

14 isn't dangerous..mine peaked at 17.1 and averaged at 15.5 on my last dyno run.. 94-95 Maf without changing Maf transfer caused it.. Put the stock mad back on, and it dropped to 12-13

sounds like a solid pull considering the age! congrats!

how much oil does it eat? have you done a compression or leakdown? - you should now that you've seen the power to the wheels.

Ideal for emissions, not for making power. I assumed when the guy doing my pulls said he didn't like the A/F where it was, it was dangerous so my bad. But anyway, compression is surprisingly good, did a test a few months back. And did no leakdown. She does eat a fair bit of oil, so I keep some with me at all times.

14.5 is a little higher than ideal, but with a stock motor it's not going to hurt anything.. Sounds like decent numbers for a motor with that many miles though..
