eewww..............5 hour drive!!

 

Good link.......
$65/hr? Regardless of the number of runs? How long would such a run take? If it take s an hour to do a run then the $130 won't be worth it to me. 260+130-->390, almost $400 for an intake......hmmm

 

Depending on the shop the 65.00 per includes setup time.
Prepare the car ahead of time:
Check tire pressure.
Check oil level.
Install the tie down hooks in the front.
If your going to do a before and after try to make a deal with the shop for a flat rate and three runs on each setup.
Make third gear runs only (puts much less stress on the engine for much less time).
Try to let the engine cool down at idle for three- five minutes between runs.
Make sure they put one or two large fans in front of the car at all times.

Good luck!

I'll call around and see how it all works......don't expect anything anytime soon from me. but when i decide to do it, ya'll be the first to know!!

 

Good advice Compaddict. Thanks to your helpful link, I discovered 2 shops with dynos within 30 miles of me, and may just hook up with them. Problem is, I have to pay for all this out of my own pocket, and am not sure I want to do that just to convince the doubters on this board. I wouldn't be doing it for me, cause as far as I'm concerned, if I like the way it drives and I feel like the car has more power, then it was money well spent. Hafta ponder on it.

Be that as it may, I know very little about a dyno procedure, but think I have a basic grasp. Assuming I do, your pointers raise a couple of questions...
Where do we get these? Where do we anchor them on the car? How much do they cost?
Please explain this. Do you mean you start from 3rd gear from a "stand still," much as you'd do on the street if you 1st and 2nd gears were broken, and you had to start from 3rd? Or do you mean to not exceed 3rd gear while on the dyno?

What might be most helpful is if you could explain the complete dyno procedure from the time I get to the shop till the time I leave. Wouldya mind? :D

 

having never dyno'd a car, i would also like the details

 

The RX-8 has two tie down hooks in your trunk (next to the jack) and they screw in the front or the rear behind plastic trim pieces.

The car only comes with two tow hooks so you have to pick front or rear. When I only had two hooks I chose the front for the hooks because I didn't want the tech grabbing the more complex front suspension for tie down purposes.

When I start my pulls I run gently through first and second gear then start logging the run right after grabbing third gear at full throttle.

I run at full throttle right up just past redline (or until I hit the rev-limiter) then get off the throttle and onto the clutch and take it out of gear. From that point the tech running the dyno takes over and applies his brake to slow then stop the rollers.

That's about the basics.

Thanks for the info.

So Vince, are you interested in contributing to the cost of a Dyno run before and after?

 

Yes, whats your Paypal account name and I'll donate.

Vince

 

I'll PM you Monday and we'll discuss.

 

Okay.

 

Wow Vince thats pretty awsome of you, but then again im kinda greedy lol.

Good luck on the dyno!

 

I can chip in a tenner. PM the info.

 

My question, if mr Huang is proven to have provided accurate date will compact apologize for being so damn rude?

I would imagine if its proven to be complete BS alot of people will thank him for his skeptisism, but never for his attitude.

 

I put the RotaryExtreme CAI in my car, and noticed a large increase in volume under load as well. Wow! Serious resonances that diminish when I back off the throttle.

 

Incease in volume (both K&N and RotaryExtreme)...pleasant and harmonious, or raspy and ricey?

 

It is a pleasant throaty resonance under full throttle. I would highly recommend the K&N based on performance, resonance and ease of installation. As soon as I resolve this opportunity with my irregular idle I will be able to recommend it without reservation. It's probably something as simple as a dirty mass air flow sensor. If any in the DFW area would like to "peep" the intake I'm sure we could meet up at the cafe or else where after hours. I am just unable to meet with you all on Wed.

I'll keep you all posted...

ANy updates, waiting for the HP increase....

 

i would love to get that answer to that same question, im debating that same thing. I really dont know, but my only comments are that from what i see the RE intake has a smaller filter while the k&n has a huge oval cone, but the k&N is open and the RE is closed so no engine heat, i dont know, but i would like to buy one of them soon!! the price is no bigdeal to me, i want to make sure i get the better of the 2

 

My friend just installed the RE Intake...it is definetly smoother on the upper end of the RPM band. The intake is really loud though when you mash the gas. I kind of have a mixed opinion about adding an intake at all now. I haven't heard a K&N...

 

everybody tells me though that you cant even tell its on when you are just idling and cruising. only when you punch it and get to the upper RMP's do you hear it

 

As 'Alex' mentioned "the stock system is as close to a cold air intake as we're going to get". If this is the case, what makes the RotaryExtreme CAI or K&N any better? Is it the make-up of the filter it's self? It's ability to suck in more air somehow? I must say that I am also concerned with 'bunglega' comment that it has made his friends car 'louder'.

I have been following all the threads on aftermarket intakes and exhausts and the one thing that I'm monitoring closely is the mods ability to increase hp and torque while adding a little snarl to the 8's note. What I'm concerned about is a ear throbbing drown, especially at cruising speeds.

My last ride had a K&N intake with a Stillen exhaust and it sounded great at idle through hard acceleration but the cruising decibles were enough to make me go mad!

It sounds if at this point RotaryExtremes CAI is leading the way due to its cold only air induction versus the K&N which will suck in more hot air from the engine. Thus possibly hurting performance? But what then about the reported gains by both companies? Where do their findings lie?

I appreciate the responses thus far and will look forward to more reading.

 

so what happens if u put a lid on the k&n?

 

A K&N drop-in filter won't gain you more than 2-3 hp. The only real advantage over the stock filter is that it is reusable. Anybody who wants to disagree with that needs to show a dyno chart to prove otherwise. These two intakes (RE and K&N Typhoon) make more power due to the sheer volume of air that they are sucking in rather than the temperture of the air, and like I stated previously, at high speeds they will both be sucking in cool air. Only at idle or in traffic will the hot air be an issue as far as limiting power gains is concerned.

 

man this has been the same question people have been asking for many years...since the renesis has no intake plenum...a short ram should be more sufficient opposed to a drop in type filter...both k&n and the RE are short ram (NOT CAI) intakes...Any one of them should be fine depending on the diameter of the intake pipe..keep in mind that even if the pipe itself is larger than the intake port you will still gain the same amount of air you were supposed to get..only if the intake port is changed to a big bore..
