Suprfly2k

Just spent about 20 minutes with my new CAI. 4k on an '07.

I switched to the RX8 from a Vette C5 and I really missed the torque when I buried the throttle. I also missed the roar from the Vette's V8.

Here are a couple of first impressions.

The MUCH improved throttle response has given me a real impression of increased torque. I haven't had it on the dyno, so I can't put numbers to it, but am I feeling my head tossed back in 2nd and 3rd? Why, I think I am!

Now to aesthitics...the tone of the engine at 5k and up is beautiful. I am happy to hear the RX8 give me some real audible feedback when I put it where it wants to be.

I've read the threads, and I've read the opions re: OEM vs. aftermarket air intake. I've seen the numbers. But, for me, there is a very real difference. YMMV.

FWIW...I'm happy to see the engine covers off, anyway. I should have done it before. ****. It's a rotary...show it off!

the engine cover actually helps the temp of the engine tho ; /

glad you are happy with it! one of my buddies just loves his too.

How does the engine cover help? Ive heard people say it reduces heat but it has holes on the side and heat rises. So wouldnt it be keeping heat in the bay for the most part?

I think the whole "engine cover keeping the heat down" thing is or was being argued about in another thread. Personally I took mine off.

But glad to hear that you are somewhat pleased with the 8, seeing that you came from, not just a vette, but a C5 vette.

does it really increase the horse power +3

romycha1

No... please tell me you were joking.

dude...you obviously dont know anything about the rx-8 if you don't know that it does indeed increase your horsepower by 3.
i just got some new floor pedals the other day (MOMO floor pedals) and the claims are around 2 hp for that, for each pedal, through the transmission.
you basically just need to do little mods like these (no hood cover, new floor pedals, etc.) to increase your horsepower gradually on this car. after a good amount of these "light mods", you'll be a savage with your scary rx-8

Ok dude... the horse is dead... move on.

yeah i was i didn't believe it and wanted to check but yeah i dont see why mazda would put a cover if it tras heat.

All cars come with some sort of *covers* these days to *show people* what engine it has.

How can you say that when the dyno day thread surely proves that those with intakes made more power? You're just repeating mindless drivel from others.

Read the thread before you post. He was asking if No Engine Cover really adds 3 Horsepower

tajabaho1

i took mine off cus it no longer fits and is rattling like a mother

Touche! Didn't read far enough up - thought this was an AEM thread.

And yes, the engine cover is cosmetic only.
