Lets be nice about it if you wanna say that at least elborate on what i said.

 

Let's not forget that shifting or otherwise keeping the engine around 6K is to deny the engine the benefit of the third pair of ports opening up. Polak is correct about the h.p. being only 150 +/- at 6K or so. That's a mathematical equation that cannot be disregarded. In stock form the Renesis is said to reach it's h.p. peak around 7,200. With my handful of mods my peak is somewhere near 8,900. I have found, as someone else pointed out, that the best launch is at the torque peak(4,500 or so). I have also found that the best shift point is 9K stock and at the fuel cut(9,750) with my mods. The only way to avoid wheelhop takes a little bit of money.

I am not argueeingw ith anybody I'm not stupid I know that you should run hte gear to the redline to achieve max power. I'm just saying that I went to the track, and it's an 1/8th of a mile, and when I shifted between 6000 and 7000 I got a 10.3 which was my best time over all. I just thaught that it seemed to correspond with the data we have pulled of the ecu with our stock fuel maps, soom have said that after 6000 we are being robbed of Horsepower. I wasn't advising anyone to do this all I said is a I also experimented with shift points and I got this data, perhaps there is more to it. I will post my can scan data with all the variables that took place during my next runs, but at this time I still have to send the unit in for the CAN update. Here is the graph that I spoke of

 

horse i meet you in raliegh last week at the meeting an you seem to know your stuff about the rotary enigine pretty weel .but i have to disagree with you on this one .if you check my times at the begiining of this post all of my 1/8 mile times beat yours .the only one that was close to yours is when i had wheel hopping really bad and had to let off the gas .i ran 9.894with thd dsc on and my bestime was a 9.595.my fastes mph in the 1/8 was 78.11 .i will bring my slips with me to the next meet which i think it is nov 13th .

 

I said I am not argueeing, I'm glads your times are better, before you posted your times I just posted what I experienced. You proved me wrong with your vehicle but someone come strip mine down because something's wrong because this is what I got, I'm not doing anything wrong, no lie, so know after saying that I am not telling people this is the way to do it and it is wierd and your numbers prove me wrong, I tired of being told I am wrong because I'm not, maybe the slips are I'll go to a different track but by posting the info I was given by the machine and just saying this is what I recieved, I am right in my case because I posted what I recieved. I didn't say run out to your local quarter and shift at 6 grand did I? SO I'LL SAY IT AGAIN YOUR RIGHT, YOUR MEHTODS ARE CORRECT, THIS IS WHAT MY EXPERIMENTS SHOWED, AND I DON'T SUGGEST SHIFTING A 6000 RPMS IN A RACING SITUATION.

 

Why does the graph show you only being at 70-80% throttle?

 

Not nearly as knowledgeable as many on this site, but it sounds like you don't have the M flash. Also I heard the K&N actually robs you of power and screws up the ECU programming/actions. Probably that is why so many people are selling their K&N intakes.

Furthermore, I also heard that the Canzoomer was best for previous flashes before M.

 

ok, so here are a few questions, to get the best time you
-take dsc off
-drop the clutch at 7500
-and change gears in 9000

right, please help, im doing a run tomorrow and want to impress

 

If you really want to impress, hold RPM @ 8,000 -8,500 and drop. You have the rest right. Short of 8K RPM, you improve your chances of more serious wheel hop.

 

it's jason's graph not mine, I do have m-flash.

 

if you drop the clutch at that high of rpm's the wheel hopping will be to bad .your time will be slower .try 5000 and feathering out the clutch .try 2 runs your way and my way and post times.

 

im in las vegas and i had ran my rx8 in 80 degree weather

came up with a 14.53 second @ 99.63mph, my 60' was quite impressive with 1.9, i too had wheelhop all through 1st and shifting into second, i launched at 5.5k thats where i got the least wheelhop anything higher just made my tires spin and catch no traction, i seem to have more trouble launching on the street then on the track

 

I'd love to see how 'wheel hop all through 1st gear' allows for a 1.9 60 footer... that seems odd.

 

It's total BS man, look at his trap speed, there is no way in hell a stock RX-8 is trapping 99mph.

 

Probably right i say post the slip.

 

I often wunder how accurate our speed-o really is, the reason I say this is because I now for a fact when I passed threw the traps at the end of my 1/4mile pass the speed-o "said" 100mph but my time slip said 93mph WTF is Mazda just playing with my mind!!!

 

Your trap speed is your average time thru the 'trap' area of the 1/4 mile course. It's an average speed, not the 'final' speed.

 

I've actually checked the speedometer against my seperate GPS system and it is off upto 2 mph by 90 mph. The GPS provides an update of speed and height every second. So the speedo shows going 2 mph faster. This was a while ago so don't quote me on the exact number it was off by, but it was not much for sure. Remember, that was based on cruising at certain speed as opposed to quick acceleration, where the speed may act a bit differently.

 

That's not true, it's your speed at the end of the 1/4 mile when you pass through the traps.

 

Right - it's average speed thru the traps...thus, your speedo will show the fastest speed reached. That will be different. You are going slower when you ENTER the traps, than you are when you EXIT the traps.

 

I see what you're saying, but the difference in MPH would probably not even be 1mph.
