-there is no intake on the market that will give you consistent 11whp gains.
-yes the average street car can see +20whp gains, but not w/o tuning

-run from that place and dont go back. for "RAM AIR" as your stating to be functional you will need a hood or bumper scoop, a large one, and it wont make much/any difference until you're starting to break highway speeds. even then gains will be minimal until you're REALLY moving.
-the type of "RAM AIR" you describe also isnt special on a rotary engine, it is what it is on any engine.
-i dont care to argue terminology or anything, but if what you describe above is "RAM AIR" - then the closest thing to a "ram air" intake for the RX-8 is the Racing Beat duct. thats the only one...
-all the others are CAI, or short ram(aka sucking heat directly out of the engine bay)

CAI is intended to get the intake out of the engine bay and all its heat. the difference in ambient temps and engine bay temps are often substantial. the difference between ambient temps at 12" above the road and 36" above the road arent likely to be a lot, but in fact its more likely that the ambient temps directly above the road surface will be hotter as the asphalt bakes in the sun.

 

so the fact that cold air sinks and hot air rises doesnt help in the case of car perfomance and filter placement?

 

go take a thermometer and measure the temps 12" above the surface of your driveway, and then again at 3,4,5 feet above the surface of your drive way.... tell me if its different and by how much.

what your saying is true, but the difference in height your talking about doesnt make a difference. also, just to throw you for an OT loop. how warm do you think it is at 30,000ft?

do this mod, and then goto pepboys,autozone,whatever store sells air ducts,and use that for airflow to ur intake..can't remember what thread that was with the air duct,but its cheap,and u don't have to spend $100's on a air duct from RB,not saying anything bad about RB products,just a cheaper route thats all

 

Actually on really hot days, the radiant heat from the road can cause air temps to be much hotter right above street level than even another foot above it.

Ram air does work. However, it's benefits aren't even beginning to be realized until high speeds. Realistically there's no usable benefit of it until around 100 mph or so. Generally that neighborhood somewhere. Maybe a little more maybe a little less. Above that speed, the pressure starts increasing at a faster and faster rate and each mph faster you get going gets a greater and greater benefit than the one before it. Racing Beat used true ram air on the naturally aspirated Bonneville 1st gen RX-7 back in 1978. That car set the top speed record for that class at around 184 mph. Ram air was responsible for 3 mph on the top end so basically without it they'd have going 181 mph. Keep in mind the horsepower benefit is much greater up there than at freeway speeds or any street legal speeds. The downside to gaining more power from ram air is that your drag is going up at a nearly proportionate rate. Only slightly less.

 

so the best way would be to just use the air duct from RB and take the side walls of the intake box (my injen)

 

i thought they said the mazda rx8 would go faster than 123 MPH

 

usually when i get to 123 MPH the speed governor kicks in

 

the governor shouldnt kick in until 145 i though? i got it up past 123 before

 

how did u do it, because mine never goes past 123 then it cuts off to about 115 and then wont go past 123 again

 

i just drove it like normal, i was on route 8 i live in ct, and i was in 4th at75, then 5th until i think 100, tehn 6th and i kept going utnil i got to 130, i had a friend in the car and he told me to push it, so i did, i didnt add any mods other than my sway bars and brakes, it was all stock

 

rotarygod....when you said speedsource was running rx8s with 230 whp what was their set up in their cars?? or do you have a site or something that'll give some info cuz i really want to know.

 

custom exhaust, OEM intake, stand alone engine management. maybe A/C delete + pullies?
maybe RG knows exactly what your looking for but the thing is, making 230 isnt primarily a matter of knowing what parts to bolt up. you'll never get close to that with any parts unless you have a good tuner

 

That's exactly it. No a/c, pullies, lightweight flywheel, ecu tuning, full custom exhaust. Stock intake everything right down to the paper air filter. Heat barrier on bottom of airbox. Stock porting. The key is in really good tuning. They tried all kinds of things and just couldn't get anymore power. It worked out at roughly 260 at the crank. Keep in mind they also run 97 octane fuel but what it is I have no idea.

No info on a website anywhere. They were at Sevenstock the past couple of years. You just had to chat with them personally.

 

yay i paid attention to something, even though i forgot the fly

 

it will

there is no speed governor on the US 6MT

you have some other issue unless you are in an Automatic tranny car?

 

paulmasoner and RG have you tried that yourselves?? and what did you use?

 

i have... my hand... go outside on a warm day and put your hand a few inches over the pavement, and put it at your waist.. which is warmer lol

 

i think he was asking about the speedsource style setup not the heat thing

 

i thought so afterward, but it was too comical to delete lol

 

ha yea I meant the setup but thanks for the explanation haha

 

ha yea I meant the car setups but thanks for the explanation haha

 

i dont know who if any have deleted the A/C, i think TeamRX8 may have for a while? I dont know that Team had one of the most extensively R&D'd and custom fabbed NA setups of any member here(he has now changed to OEM i think). with all of the mods he did and some very good tuning he put down 220whp IIRC...

 

thats very decent for the car, its just kinda sad how tuning wont change that much on the rx8. whats IIRC? and also, i dont want to put in a turbo just because i dont want to risk over boosting it, i usually dont hold back once i throw a turbo onto anything

 

this is one of life enjoying
