Dyno test 6spd RT

I have a block scheduled for a chassis dyno this next week. Im getting the RT out of hibernation and going to dyno it bone stock. I have 2600 miles on it now and want to see how much gains from 1 dumping conventional oil and replacing it with Mobil one synthetic. and 2 installing a drop in K&N. Only cost 75.00 so Im gonna have some fun.

Anything else I should try while I have a block of time on the dyno?

Just for grins, disconnect the intake tube from the airbox (leave it connected to the throttle body) and see what you gain, if anything.
Please post your results, and please let us know what kind of dyno it is.

wow, 18 hp and 20 ft lbs of torque just from a air filter change in the stock box and oil. That's a huge and easy pop.

Nice testing and what I like to see.

Maybe synthetic is good for about 3-5HP and a few ft lbs.

You can switch whenever you like.

Personally, I do three break-in oil changes on a new motor. I do one at 250 miles, another at 500 miles and a third at 1,000 miles. I'll then do my next oil change at 5,000 miles on the clock and every 5,000 miles or 6 months there after.

So I stick with regular dino for at least the first 5,000 miles just because I don't want to waste the good oil changing it so often.

Dealer told me that 5000 miles was fine for 1st oil change, and it waste of money to change earlier. Once upon a time, new cars needed an oil change after 1000 miles just because of sand and manufacturing gunk, but that's not the case now.

Is there actually a break in period on the car? I saw nothing in the owner's manual about it, so I started hammering it as hard as the car would go as soon as I took delivery. I was hitting the rev limiter and doing repeated burn outs and WOT acceleration with just 40 miles on the car.
