Engine Dyno #'s
I was hoping for 600 HP... but came up twelve shy. Not to shabby for a daily driver/Nitrous motor. This motor isn't a trailer queen race motor, it's built for the long haul. This means some things were left in or out for the sake of longevity. We gave up some compression, smaller cam, pulled some timing along with heavier pistons and rings for the NO2. All things considered I'm pumped! The power curve with the old set up was great and this set up is even better. It made peak power @ 6200 rpms and held within 2hp of peak from 6000rpm thru 6800rpm. What a stump puller, it makes over 300 hp at 2900 rpm and never looks back. This darn thing makes less noise than a stock motor. No ticking ect... Idles at 750 I'm hoping with the fatter power curve and extra pony's it will run a tenth or two quicker N/A. And I like the idea of having a low rev motor with ton's of torque..a great street motor.
Anyone want to guess what it will put to the wheels :eek:

Re: Engine Dyno #'s (Ripped427)
Dennis, congrats to your great numbers ! Is this a DRM built 427 engine ?
I got the numbers from my DRM 427 being dynoed April 10, the peak was 586hp at 6100rpm and 557ft/lbs at 5000rpm. It made more than 450ft/lbs at 2600rpm :eek:
I assume that we need to remove 10-12hp for the accessory drag when installed in the car but still great numbers :D :D
:cheers:

Re: Engine Dyno #'s (seanr)
Seanr, you got it, it was the DRM motor great numbers!... Your motor was a little stronger than mine actually. My heads were ported last year and Doug made some improvements since then. (Yours out flow mine on the intake by 15cfm) Yours is a real monster, have fun and keep us posted on what the locals think about your new power plant..
The ARE 422 that I purchased from Godspeed will go on the dyno after we get back from Bowling Green. But I want to talk to Nick about getting a smaller cam before we run the motor.
