I just got back from a chassis dyno tune today. The operator did one low rpm pull to check out everything. Wheel hop, vibrations, etc. then one pull to 3000, let her cool and made adjustments on my computer. Another pull to 5000. Cool time and adjustments, a couple of more pulls, one to 6000. He let it cool between pulls.
They should watch what it happens and take each pull a little higher in the rpm range.
Jon told me a story of a kid that drove his car to the dyno shop. On the first low rpm pull the new trannie cracked. When they checked the driveshaft, it had one bolt missing and the other three were loose. He and his dad had forgot to tighten them.
I have had my Cobra dyno'ed five times before. Some were just to see what I had. 3 or 4 pulls in 30 minutes, not much cool time between pulls.
The guy today did the best job.
Jon charged me 4 hours, $350 total.
This shop does 2 pulls for $50, which is the best price I have ever hear of.
We're going to take a few Cobras next month for a dyno day.
Should be fun
