Dyno numbers for my '310 hp' NA Honda

[Payne]

Here's my dyno sheet. Red is with the factory intake setup, blue is with a straight intake. A few observations:

• The factory Ariel intake is TERRIBLE. I picked up 14hp *untuned* with a straight intake with a bevel on it, and at least 500rpm of powerband. I'll be fabbing a 3" intake under the driver side shock with a good filter and sock.
• The factory header is TERRIBLE. I'll be getting another header built over the winter and should pick up ~20hp.
• These numbers are for a basic, safe tune. There is probably 5-10hp more in it with timing and fine tuning across the powerband; however, I did want to spend 6 hours getting the tune perfect and then redo the intake and exhaust.
• I'm quite happy with the numbers. The car will outrun my supercharged viper, and it would take a 150 shot or more on my 383 z06 to run with it. It's spooky fast.
• Well built motors > superchargers on stock blocks

For reference, here's a stock AA2 Honda 300 dyno and a Brammo dyno run:

rotrex that son of a bitch!

rotrex that son of a bitch!

Not at 12.5:1 compression... not without 116 Octane.

With different slugs this motor could easily make 600rwhp. I'd probably destroke it with a F22 crank though and spin it to 10k just for grins.

Let me figure out how to not dead myself with 300rwhp, and then we'll turn up the wick.

yeah I know


but the rotrex sounds like a jet engine......seriously stiff wood there.
