F430 New Dyno Numbers

It's interesting to follow your posts of 430 dyno results but, unfortuntely, it's hard to know what to make of them. If, for example, you'd done a dyno of your 430 w/o the hyperflow cats and BMC filters and then another dyno with the hyperflows/BMCs, we'd get some insight into "performance gains" associated with your modifications. In this case, your dyno results would have some interpretive value, assuming same dyno, similar conditions.

But in your case, you seem only to have an "after" dyno with the BMC filters and hyperflows. Two other posts of dyno results on a STOCK 430 claim 427 RWHP and 430 RWHP. If it was useful (and it isn't) to compare dyno results across cars, the results on these other 430s would suggest your modifications resulted in LESS RWHP on your 430 than stock. But, as you know, its meaningless to compare results across cars.

Finally, assuming 420-430 RWHP is about right for a 430, the implied drive train loss is around 15%. No one, of course, knows if its actually 15%, 18%, or 20%. Safest bet is to use the generic 15% unless one is a wishful thinker. Wishful thinkers may be inclined to use 20% as it increases the estimate of HP at crank making the car, rendering it closer to factory specs at crank or it makes the imputed gains of modifications look better.

And so, bottom line, is a post dyno w/o a pre dyno offers almost no information of any value. Just my take, having done dozens of dynos, learning my lesson, and even finding great variablility and contestability in pre- vs. post-dynos. Life just isn't fair.

Good luck and enjoy at any rate.

 

I have been searching for dyno graphs for the F430 everywhere. I have seen numbers from 330rwhp up to 445rwhp.

I'm curious what other cars such as the 996 and 997 GT3, 360CS, C5/C6 Z06 put on the same dyno.

I have been unable to use the 1/4 mile times/speed as an indicator of power, because the U.S. version F430 can be anywhere between 3,100 lbs and 3,400 lbs for the coupes (add more weight for the spyders). A 300 lbs weight penalty really hurts the acceleration.

Ferrari claims 490 Hp at the crank, the important number is the one the car puts down to the road, and that doesn't seem to be in line with the claimed figures.

Am I right on thinking the stock F430 is producing something like 450 Hp at the crank for the U.S. versions?

 

Great thread. Thanks for starting it.

 

430 WHP is WAY more than 450HP. I would say that it is in line with the claimed figures. The 360 was slightly overrated and the 355 was highly overrrated.
