/\what?

 

Some of us have found that the Holden Monero/Pontiac GTO wing works well too.

 

Please take those fins off.

Now


kthxbye

 

^agreed

 

tell em tim unleash on em. that really annoys me too. btw why are the fins angled just wondering never seen em that way before

 

its not bad, but with both those spoilers on there so close to each other i makes me wonder if your car wistles at high speeds lol.

 

I've never seen vortex generators on an rx8 before, not too sure about that. I think it breaks up the smooth curves too much. Functional or not they just look a little out of place on an rx8. I guess you can take the man out of the Suby, but you can't take the Suby out of the man, lol. Anyway I like the WRX spoiler, but if it were me I'd loose the lip spoiler and one of the third brake lights.

 

{begin rant}
Complete BS, first off vortex generators are used to trip the "boundary layer" concept which will un smooth the air(math term, doesn't really exist.) Second, having them angeled will not do a thing to the momentum of the incoming air. THIRD the spoiler is in no way designed height/width/length wise to even see the disturbances generated by the fins, if they even made any to begin with. Fourth the aero properties of the car (which isn't that aero to begin with) negate any possible changes you can add. Ask speedsource why do don't have them on there car which has a proper spoiler to see any effects from them. also ask them about there wind tunnel testing.

Then he should have told you what I just did.

Yes i have a degree in aero engineering.
{end rant}

{beginning of praise}

I actually think the spoiler looks great, it really does flow with the lines of the car. When you first stated scooby spoiler in the title I was expecting the stack spoiler from the 2003 to 2006 wrx which probably wouldn't match at all. But yours looks almost stock, get it painted and clear coated and i think it'll look great.

{end of praise and post}

 

i think the spoiler looks good too...i think it looks way better than putting the GTO spoiler on our car....just get it painted

 

looks good!

 

Respect to the rant and i don't know as i don't have a degree in aero engineering but i have taken his advice and the proof is in the pudding fella and the fact is my car feels more stable and safer over 100 mph. And thats all that matters to me, plus i like the look and seeing as it's my car and the thread was initially about my spoiler that's all i need to say.( rant over)!!

Thanks for the comments one and all. Like the manaro spoiler looks good!!!

 

I think the rear tail looks damn good, not so arched like a Mickey D's sign.
Good job Tim, now git-er painted up!!

 

There is a kid around here in a old Ford Probe with double decker spoiler and vortex generators. I guess I should have not laughed at him because he must have talked to your cousin.

PS the RX-8 is planted to the ground like glue at +100 speeds already. Any effect you are feeling is a placebo.

PPS I do like the WRX type spoiler, just not the fins.

 

Wolverine has those "fins" as well.

Thank god i am not the only one, was thinking there was a hate campaign against me !! lol

 

spoiler actually fits the car pretty well. i personally would not have installed the fins on the roof because i think they look out of place and i dont drive over 100mph often enough to need those..but function over form is a statement i truely understand.

 

Fins just don't fit the rx-8 imo.

 

the spoiler looks really good. not a big fan of the lip spoiler as well though...

get it painted nad you're in business

 

i like the spoiler, but i would color match it to the car

 

here is an idea for the 3rd brake like fiasco..... tap the original 3rd brake light to the parking lights and debadge the trunk.... so now you would have the "RX-8" glowing on with the parking lights.

 

Liking that idea, thanks fella!!

 

I bet he raced with Impressa and EVO MR and won the spoiler and fins from them

 

I agree with some of the posters about filling the brake light on the trunk lid. Personally I would get rid of the lip spoiler and just keep the wing, but if you like it then by all means. Also I think it would look better if the wing was painted to match the body color.

 

Not really... Vortex generators are used to create vortices (hence the name), which charge the boundary layer in order to keep it attached to surfaces operating at high angles of attack, an effect which decreases wake turbulence, in this case, over the rear window. They do not "un smooth" the air... the effect is quite the opposite (like in this youtube video).

Verbatim from Wikipedia:



Having them angled is how they generate vortices. Look at any picture of VGs on airplane wings and you'll see that they're set at an angle to the incoming air.

Again, verbatim from Wikipedia (with citation):
Any possible change? So the RX-8 can't benefit from any aero improvements at all? How is it that a car which, according to you, "isn't that aero to begin with" couldn't be improved upon? I'm sure I'm not the only one interested in the aerodynamic properties of the RX8, so please, enlighten us.

If they'd be willing to share their proprietary (and expensive) wind tunnel data with the rest of the world, I'd love to look at their numbers!

What does that say about our education system?




I haven't personally tested VG's on the 8 (yet), but the internet-available testing done on a multitude of cars (including the video above) all points to them being effective in at least keeping the boundary layer attached to the rear window. Some of the tests, including the HybridZ guys (who rented a wind tunnel), Mitusbishi, and AutoSpeed also report decreased drag with VGs, and some of those tests also indicate decreased lift and improved stability. In addition, none of the tests I've seen show any harmful effects from them. They may not help the 8, we won't know until someone does a scientific test of them, but the theory is certainly sound.

 

remove lip spoiler, remove window brakelight, remove roof fins. then
