The Moroso slide rule shows 500hp/3200bs as 10.50@126.5.
7% loss is 465hp, which shows 10.71@123.6.
10% loss is 450hp, which shows 10.81@122.2.
If it really weighs 3200, and won't go at least 122 at a NJ track in the spring/fall...... Either there is something really wrong with the set-up, or the dyno numbers are happy(or a little of both).
I always thought the Moroso slide rule was based on RWHP?
Last time I weighed the car it was 3,060 without driver and a full tank of gas. Since then I've taken maybe 50-60 lbs out and will be taking more out soon with a 'glass hood. I weigh 187.
Engine was dynoed at Merkel's here in LI. I don't remember what the DA was that day but it was clear and not terribly humid. The operator used a psychrometer.
I got all excited when I saw it flash to 520+ hp on the screen but with the correction it said 500.2 on the printout. I thought it would be a little more. It was fairly consistent in that range though so I don't think it was a fluke. There wasn't much in the way of tuning.
You actually commented on it when I posted the results.
416 dyno day.
