Britsh V8 2014 - Dyno Day Runs

For all of you that attended today's dyno event -- I don't mean to burst your bubble -- but those results were corrected to STP (standard temperature & pressure) using today's temperature and barometric readings. So what you got were sea level numbers , not the values at altitude :-(

It was interesting seeing two other dyno results being pretty much the same in two different states. The one in Colorado was a bit less in results, but dyno's are a tool and not in the seat feel results.

Are everyone's dyno results posted anywhere? I'd be interested in seeing them.

For what it's worth...I was talking with the gentleman running the dyno before we started and he told me that their dyno typically gave low readings. This was the first good run on a dyno for my car (no fuel pressure issues). This dyno had my max torque at 322, the dyno in Texas showed 341, both at 3500 rpm. My max horsepower on this dyno was 308, the Texas dyno had me at 303 (while running out of gas because the pump couldn't keep the pressure up). I was pleasently surprised that the torque curve is as flat as it is with 300+ ft.lb between 2800 and 5300 rpm. Had fun and learned more about my car, well worth the price of admission.

Jim,

Curtis has all the print outs with him, so I'm sure he will post them up soon! I think mine was 383/376 on this dyno.

Thanks, I have to live the event vicariously since I couldn't be there.

Yes Jim, but there's still, Hot August Nights= hint ?

Post the results? Mine were so bad I'd be embarrassed! Combination of altitude (7000') vs Houston (43') and probably also way too restricted air flow (Palestine was done with air filter removed and 2.25" exhaust in tail section; COS was with 2" filter and exhaust drops to 2" where it goes through my IRS.

I'm thinking I'm going to redo the tail section of exhaust to get it back to 2.25 and see if a deeper drop base will let me fit a 3" filter. Maybe even a Performer RPM or air gap vs the Performer 289 I have currently.

Also considering a carp swap to 600cfm vs the 650 I have. But Ford manual for my engine recommends 600-650 and I'm still planning to convert to EFI when I have money and time so want to minimize investments that won't be applicable.

Net, thinking I'll mess with exhaust and intake first and see what happens.

I enjoyed being a spectator this time at the dyno event. Gave me time to shoot some video.

Here's Phil's run:

Phil's was definitely the loudest.
