Hitting the Dyno, Should be fun.. Options

[Jetsetsurfshop]

Hey Everyone,
I have a dyno appointment coming up next week. Is there anything that will take me by surprise? The guy running the dyno just said to not forget gas.
I plan on bringing, fuel, straps, fans, and my weber jet kit.
Can anyone thing of anything else required?
What RPM should I stop at? (IMG:style_emoticons/default/confused24.gif) My car has larger valves (48-38), duel valve springs, solid lifters and a 494 webcam.
Heres more info on the car.
2258cc
10.5 to 1 Compression Ratio
40 webers
Tangerine headers
98 octane fuel
What do you think she'll make at the wheels?

The few times I've been on the local chassis dyno, we always ran in 3rd gear. IIRC, they said it had to do with how long the run took. they were trying to get it to be about 10 seconds. My buddy tells me that the fuel/air ratio will change with the different gears. Higher gears tend to load up the engine more and draws more fuel causing a richer mixture. I'm not sure.....just go with what the dyno operator says (IMG:style_emoticons/default/biggrin.gif)

Has the engine been broken in yet? It's hard to break in an engine on a chassis dyno. Make sure you have it broken in before trying to dyno tune it.

Have a good selection of jets and tools to change them quickly. Most dyno guys are used to making changes to your electronic fuel injection and don't have a lot of experience with Webers. You're basically going to be changing main fuel and air correction jets.

Be careful to roll on the throttle and not just mash it down. The accelerator pump will screw up your bottom end readings.

I'm sure there is more......just can't remember it all right now (IMG:style_emoticons/default/biggrin.gif)
