Well it's been a couple weeks and I still can't believe we actually won. But, the best part was getting to see so many killer rides getting the snot beat out of them.
It was also great meeting new people like James and seeing new cars like the One Lap Camaro and the Motivator (don't worry Larry, you can run it next year). Was also nice to see some cars again like Fuel and killer rides by Air Ride and DSE. It was just plain FUN!
I drove the '68 out to Vegas from CA and it was running badly.. it was surging and just not happy. I attributed this to the fact we wern't able to tune the car before leaving.
So the car held together and David and Mary beat it to death just like I told them to. Besides a problem with oil blowing out the breather all went well. We now know what suspension stuff needs to be done for next year. The car has a LOT left in it.
So today I finally drive the car over to Westech for some chassis dyno tuning. So we strap it down and make a baseline pull.

Wow, those are some pretty weak numbers for a 402.. we continue to fiddle with the tune and even though it shows lean it smells rich. After a bit Ernie notices an anomoly on left side O2 sensor. We check the plugs and find this:

Number 5 cylinder.. the fuel we smelt was gas just washing though that cylinder since there was no fire. I drove to Nevada, and we ran in the challenge on seven cylinders. doh!
So, we tossed in a new plug and picked up 70 hp and tq to the wheels... after a bit of tuning we maxed out at 474rwtq and 481rwhp. A HUGE improvement over what we had. The car is nuts to drive now, it's like I added a blower. lol

The plug must of been broken when we lifted the engine to change the pan. I kind of feel stupid for not checking it, but it didn't run THAT bad.. not like it was on seven.
Monday we finish part throttle and idle tuning and then we change the oil. After reviewing the video I can tell I need an oil cooler. By the third lap my oil tems were up from 200 to almost 300 degrees. Glad I'm running synthetic Torco.
Here's a video of the dyno pull. It's crappy since I took it with a cheepo camera.

I'm downloading a low res video of three laps around the Spring Mountain track. Will post when it's done.
Already planning a host of improvements for next year. Mabey I will actually think to put a decent alignment in the car this time. lol
