BTW, does anyone know if there is something that doesnt allow dynos to calculate torque for rotaries unless you have a special tool? Not sure they were right, but the dynoes were cheap; they were only 30$ for 2 pulls. :rock: :rock: :rock:

Did the dyno shop tell you this? :Eyecrazy:

BTW if you want to measure torque for a given horsepower/RPM:

Torque = (Horsepower * 5252)/(RPM)

so if they gave you a HP curve, you can generate the torque curve that way.

i only got 179.9 with just my sr motorsports pulleys when i did my runs.....i yet to do it since i dont my other stuff

I thought its 180 stock?

^if your lucky...

lol yup but on the other hand if you have some mods :smoker:

I would like to get my car on a dyno sometime soon.

rpm pickup can sometimes be tricky. if they don't pick up the rpm, you aren't going to get a torque number.

You have a MT right? No way is that right. check your coils
What dyno was it? I think in a socal dyno thread a while back deedub had the hks intake +exhaust and dynoed ~190ish

That is news to me that the car doesn't produce near what mazda rates it at. Or do they just measure at a different point on the drivetrain? I guess I will do some reading...

Nice video

nvm I figured it out.

Numbers will vary on each and every dyno because variables like calibration, weather, D/A, etc. have to be put into the calcuations. As a result of this a dynograph should be used as a base method for tuning and, IMO, nothing more. You could go to another dyno shop in town and make 10hp more, or maybe even put down 5hp less.

Cars that are coil-pack-equipped like the RX-8 can be sometimes hard to pick up an RPM reading on when they hook everything up. Like said if they have problems picking up RPMs you won't be able to get a torque calculation.

Also, the RX-8 is severely overrated as far as the horsepower number goes IMO. If you get 200-215 crank horsepower (180-190whp) out of your car in stock form I think you're sitting pretty good.

Lastly, track times tell the truth on your horsepower numbers a lot better than a dyno will. The dyno calibrations can be changed to make your car have 300hp if they wanted to. The track, on the other hand, will not change them and will not lie.

dynojet I assume?

yes it is a mt, yes it was a dynojet. They said that it was 165 "SAE" corrected. It was a colder day... Anything that I should check? I mean, the car still runs like it came from the dealership :)

Check the coils & plugs.

engine compression

check plugs and coils when you get a chance.

i mean, the only place that i know of to check this stuff would be at the stealership. It is under warranty, and they have seen my mods before. they didnt really care...

plugs and coils you can easily check yourself.

^lol. okay then :) What is the easiest way? --- newbie question :)

plugs are easy.

- jack up the front left side of car
- insert jack stand
- remove wheel (loosen lugs BEFORE lifting car. ;) )
- straight ahead are the plugs.
- Brown is okay, black and white spots are bad.
If you've got more then 25,000 - 30,000 miles on those plugs, might not be a bad idea to just swap them out.

Here's how to check the coils:

Did you do this at Rotary Performance in Garland or did you use another shop?

The plugs are easy to get to get to on this car, they are out in the open and are right down where the oil dip stick is on the driver side.

You'll need a sparkplug socket as well. I assume you probably don't have one.

This is the one I use: cheapest I found and comes with other sizes:

They are useful on the lawnmower too:)

my car only has 10k miles... Not a good sign :(

what year? It's possible the plugs just got fouled up on a cold start.

2006. also, the car was dynoed at Corvettes of Dallas. My family friend bought it so I kind of have a connection there.... :). I do need to check my plugs then, eh? What do you mean by them being colored brown, where would they be brown?

because that's what spark plugs do

wait, we were just talking about plug wires, and now you are talking about spark plugs :lol2: :lol2: . What colors brown?

Mayabe, they faked the dyno. :yelrotflm
I bet you killed the plugs lol

^I am going to check it as soon as I get back from michigan this weekend hopefully... ^OK, the plug then :)

Alex, ur doin pretty good at that range IMO. Like others have said, u could go to another dyno in a another part of town and be at 180hp maybe even 185. Whats important is how it feels, and obviously it still feels great, so....

I will be hoppin up on the rollers soon for a session testing out some flashes. My car "feels" as good as it ever has, so whether it puts down 170 or 190 on that particular day at that particular dyno doesnt really make a diff to me. Only differences im looking for is with the flashes:)

I recall you talkin about ur hookup with Porsche (used tire hookup), now ur in with the Vettes too? Big timer.

Stop over someday and i will show u how to check ur plugs n all that. It will be easy for you cuz you have skinny arms and a wing span like Shaq:)

wait, we were just talking about plug wires, and now you are talking about spark plugs :lol2: :lol2: . What colors brown?

When you take the plug out, the side going inside the engine that tip will be brown.

^next meet ill bring my jack (that i got in january :); unfortanutely a necessary purchase) and well check it perhaps

its all good. the conditions can vary which can make the hp vary. you have to look at altitude, humidity, temp, and oxygen content in the air.

I have heard reports of 8's dyno'd at 165whp and the owners are none the wiser, stating the car feels as strong as ever, but i guess thats all relative.

^ exactly. just get it dynoed a couple times over the next couple weeks at different times and average the numbers. especially if you can do it for so cheap. also check the coils and plugs as previously stated

butt dynos still suck

Thats pretty good. Now just pull the fuse the next time.
