Hi guys,
I will get back with some answers. I am on vacation until the 27th |
Silly Question,
You mention you broke 200mph, but the pictures indicate 140-150kias at 7500ft. Is your reference of 200mph the ground speed? I mostly ask because I normally see 145-155mph indicated airspeed when I'm flying at 11,500ft with a 200mph ground speed and clam winds. I just want to see how my 8 is performing compared to everyone else. :D |

[quote=judoka5051;1039195]Here's a couple of pics ("I hope" says the caveman) this is a little different than what I did on the RV8A. The 6 exhaust is angled much more sharply down, so no center piece. The ramp that guides the air out of the cowl is likely as responsible as the 'flow straightener', but I'm too lazy to take the cowl of just to get a pic. Sorry about the dirty bottom... been doing a little acro.
Lance: I'm very interested in the exit ramp, please post a pic when convenient. Don |
Hey Lance
What performance improvement did you notice with the exit fairing extension? Cheers |
Picked up 6mph!
I did a before and after within an hour, at the same altitude. So, while not 'scientific' it's close. The plane didn't have anything to direct the airflow out of the cowl (unlike the 8). Just the firewall and a sharp 90 degree turn at the bottom. So I added a ramp that is riveted to the top of the cooling exit and curves up to connect to the lower engine mount tubes. I've read many times in different place that it is important to get the exit air 'headed in the right direction' which makes sense. I added the exit fences at the same time, so I don't know which of the changes made the most difference, but I expect it's a synergistic effect.

As my English is not so fluent, I'd like to clearly understand what you did speaking about the "ramp". Could you send us a drawing (very simple). About fences it's clear, but do you thing it could be better to close the bottom between the two fences, and to have two straight exhaust pipe blowing horizontally. Have a nice Christmas |
