golden child, I don't think there is one on there for Macs to play WMP 10. M$ needs to come out with a WMP 10 verison for Mac before developers can get there hands on the codec to use in other apps. Neither VLC and MPlayer have WMP 10 codecs for Mac. We're stuck in the audio-only realm for now.

Is there any utility in running on the dyno from closed --->open---> closed to see a change in the slope of the torque/h.p. curve?

the butt dyno says the exhaust as a whole makes power over the Milltek no doubt. The difference between open and closed is really weird...because the sound adds to the speed like "red" is the fastest color. I will say that particularly when you are at the top end it is coming on like a scalded dog at red line. I think the redline could go up to 8K without a problem (maybe blowing something up but it wants tokeep making power..... on the videos I am shifting below 6K on the going away runs ..... the point is mute because I will dyno tonight and give the results to Randy who will be in charge of letting people know where we are so far.

you might try a stop watch between say 50 and 90 mph, same gear (5th?) comparisons.

I'm at the dyno waiting my turn......there is very nice 2000 corvette convertible putting out close to 600 whp working on the O2 shot for tommorrow's drags in Brainard.
HMMMMMMMMMMMMMMM

Long time listener
Spider,
That thing just rocks. I had been listening to it all day on the laptop speakers, just got home and got to listen on the real speakers.
Randy will have me beating down his door if it is even close to that sound.
Keep up the good work.
Lucky for me I only have to drive 250 miles to have it installed at Randy's Shop.

that was just beautiful...
I love this freakin thing man!

That thing is sick man... sick! I'm not sure how much I would run it with it open, but closed I would be a bit more open than what you had... I don't know it's all preference.
But this is what I wanted my MINI to sound like from the begining, it almost sounds like my dad's M3, which by the way is on order!




I congratulate Randy and SpiderX for a job well done!
Do you feel any power difference between the two when you accelerate?

Cant wait....when this is installed and someone pulls up and says,.....that is so cute. Then you flip the switch and ring the ear drums...WHAT DID YOU SAY???

. I have no idea how long though. Tonight, I'll go out and put in some runs on my car [Cosworth Stage II+ but between software revisions, so just stock tune]. I'll report back. Sounds like a fun 30 minute study break!

Also I went out and did some runs timing 60-90 and the open position was about a full second faster. I did about 4 passes each and that was about the average.......not very scientific/clinical or laboratory like but the price was right. I used a timex "Ironman" watch which is accurate to the .00

Just tell us this Spider, if you can.... Does it make at least as much power as the Milltek?

On one hand, you're checking out a prototype product for Randy, and I totally understand the idea of him retaining the right to post dyno results. On the other hand... Lots of people out there have posted dyno sheets on lots of products without anyone else's consent... Randy being one of them. :smile: I can only accertain that he's asked you to hold off until... well... until he gets a final production piece put together.... because those are the real numbers any of us should care about.
