Dyno chart of bone stock 6MT RX8 for your pleasure and mine.
Howdy all:
Just got my car dyno'd today at Rotary Performance in Garland, TX (great place by the way they were nice and I plan on going back)
![](http://img139.imageshack.us/img139/2134/dynochart1wa.th.jpg)
The only thing I have in my car is the K&N Drop in filter, everything else is 100% stock. That changes tommorow because while I was there I picked up the RP Supercat midpipe from Rotary Performance and get to install it tommorow... it will be paired with my stock exaust for the moment until I can save up for a racing beat REV8.
182HP to the wheels in stock form... I'm guessing thats good? I'd love to get 200 to the wheels... what would be the best strategy for getting there after the CAT and the EXAUST? I'm looking at a flywheel next... and planning on skipping over the REVi intake... in my mind cant justify almost 400 dollars for 1HP and 1MPG...
any suggestions comments on the chart are welcome! cheers!

First of all - thanks for doing this. There are precious few dyno charts for bone-stock cars out there, especially from reputable shops like RP.
Second, 183 is pretty decent. That is right in the middle of the few other stock RX-8 dyno charts out there. They range from 160 to 205 or so, with the typical falling in the 170 to 190 range.

You're probably not getting to 200whp without some sort of EMS. If you're not happy with the stock power get yourself some FI, if you are happy with it then I'd just do the exhaust and be done with it.

pretty much looks exactly like mine, absolutly bone stock, nothing chaged at all. 40,000 miles.

cept my car was having a absolute bitch fit about being on the dyno. rpm was stuttering and it was pulling power... either TCS/ABS was doing it or the exhaust was too hot and engine cut/added fuel for sake of the cat..
it was also 103 inside where i did mine, after each pull, my car was hot as hell. had to wait about 10 mins between.

Yes, but a 200HP run on one dyno could be a 190HP run on another. My old civic coupe pulled 240+ on one dyno and well over 250+ on another on the same day just to prove a point to my buddy who's mustang ran less at one than the other. We were arguing which facility was best. So just make sure you do all of your tuning on the same dyno.

Intake? Technically you're not bone stock. Good numbers though. Pretty typical. My car consistently gets 190 RWHP. But I'm not stock either. A friend of mine gets 203 all the time. Not typical for the car and his car has the same mods as mine.

As that link I just posted shows, that 200+whp run was done on a dyno where several other RX8s were running; his car was an anomoly.

That wasn't a crappy dyno. That guy's car made a LOT of power. Read the thread to which I linked - that run was at a DYNO DAY with MANY other RX8s. His car consistantly made MORE power than other stock RX8s.

A K&N drop-in filter is not an intake. It's a filter and good for zero HP gains.

His car is stock.

thanks for the input guys -- I'm glad I could "help out" in a way with the dyno charts... really I did it for myself but I like sharing info for the 8s ![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
yes even though I have the drop in filter, I still consider my car stock because there isnt really any tangible gain to be had with it.
On the subject of more power -- FI is just not in the cards for me right now. I still have 80K left on my warrenty and I'd like to get at least 1/2 thru my warrenty before I slap on a FI kit. It's also a money thing, I'd have to save for a while to drop 3K+ on a turbo + tuning etc.
I'm very happy with my car right now - the CAT and the REV8 exuaust are "do-able" mods for me right now. After I get a good amount of MODS on the car I shall be going back to the same dyno for another set of runs to see what i've gained, because 1) its the only dyno shop I know of thats decently close 2) its the only 100% dedicated rotary shop so I trust their equipment and 3) it was only 55 bucks :-D and 4) they were great!
As a side note - I did this on friday but memorial day traffic was HORRIBLE... I left NE Fort Worth at 11:40am and did not get to Rotary Performance till 1:20pm.... i literally spent all my time idling where 183 meets 161, took me 25 minutes to go ONE MILE. but it was worth it :-D

100, maybe 120 to the wheels? I don't really want to know because its kinda sad either way. Thats close to my last car I had, 100HP Saturn, haha and it sucked.
Oh yes this reminds me: at the rotary shop chris? i think his name was, when I was giving him my keys and we were chatting he asked "AT or Manual" of course mine is a manual so I told him and he said "good" in response and smiled. LOL gave me a good chuckle.

I'm right there with ya - but I figure if I'm after 'just a number' I'll hook up a leaf-blower to the front of my REVi on my next dyno.

And an K&N drop-in is stock for the purposes of this thread. It's not a power-adder. Stock could also mean "never having changed from the oil which came with the car" - but in terms of describing a car's power-making potential or ability, I only count power-affecting changes as being non-stock, for example headers or intake or exhaust work.

this is just the Drop in Filter... not the whole intake. Ive heard stories of people LOSING horsepower with certian intakes (non- REVi)
I dont see how this drop in filter could possibly SUBTRACT power... it's the same size same dimensions just free'er flowing... if i blow air at it, i can actually feel it on the other side, versus the paper filter where its like blowing at a solid wall.

Two ways (both somewhat esoteric):
1) The filter uses an oil to enhance its dirt captivity. This oil eventually coats the MAF wire, screwing up your idle and, to some degree, your power.
2) The filtration is significantly less dense. This is the trade-off you make for flow. In the long run, you are putting more dirt in your motor. This will eventually cost you power.
Neither of these are really a deterrent - Clean you MAF when it needs it and drive your car hard. It will wear itself out much faster than the dirt can.
