New engine dyno.....

Post by jadams » Wed Jul 18, 2007 12:29 am

Well dynoed the car tonight and seems to look promising, but developed some kind of ignition miss as the tuning progressed. Looks like the coil is going bad, or the coil wire. Should be an easy fix though (hopefully). Engine made 420 rwhp on early pull before the ignition problem surfaced.

Here is dyno graphs

Engine HP

Good HP!! Hopefully you can break it in before racing it. I used to put some fans in front of the radiator, open the hood, set the idle speed to high (2000 rpm) , fire it up and walk away for an hour or so. Good Luck with this one.

Looking good Joel. Don't forget to check the plugs before throwing other ignition parts at it. Engine break-in is a very controversial topic, and I know everyone just wants to help and make sure that the engine lasts a long time and makes great power, but an hour on a high idle is not (in my humble opinion) a good way to break it in. At this point the engine is already broken in and ready for anything you throw at it.

Here is a great article on the subject: http://www.mototuneusa.com/break_in_secrets.htm
