I think Rix would agree call Wayne and get a Syvecs :-)

 

Wayne @ ISC is great with the Syvecs.

Actually I have mine up for sale right now - I am moving to the S7+. With the Motec dash I added to the car, I want to be able to send CAN frames back to the ECU to trigger commands. Unfortunately, the S6+ can't do that, so I want to upgrade.

Have done a little more development on the dash lately. Here's some pictures of the design in Motec Display Creator.


Bootup screen, an artist did a cool caricature of the car for me a while back. Seemed like a good place to use it.



Main driving display, has pretty much anything you'd want to know on it. I'm probably going to change a lot of it over time, but it's a good start.



This one is just for in the garage, or pits at the races so I can check as many variables as possible. Probably going to shrink them and add more fields for this purpose.

 

Yes this. I haven't been as forum active lately but have been a little more engaged since the half-mile season officially started this year in Kansas for Shift Sector.

 

 

 

Oh, I actually figured out how to get the correct weather data into vBox Dyno. Made a little more power, 1375.

Pretty cool really. The Xona Rotor naming convention is "7164S". That means it has 71lbs/min compressor wheels, and a 64MM turbine outlet. The S refers to the "splitter" design turbine wheel (aka Ultra High Flow Turbine). If you want to know how much power a Turbo is "supposed" to make, just take the pounds/min and multiply by 10. Xona does in fact underrate their wheels a little bit from what I've learned talking to them over the years, but suffice to say I was using all of the turbocharger on this run. ~150k RPM shaft speeds and 40psi of boost.

71lbs/min * 2 = 1420hp, observed was 1375 when I re-ran the numbers above with the correct weather (pressure, humidity, temperature).

I think I'm out of Turbo now . I'm eyeballing an 8264S, which would support 1600hp+. I think I've gone crazy.

 

ya think?
lol, congrats on the beast though.

 

 

Wow...the 4th and 5th gear acceleration looks nuts, never mind the 3rd gear thrust! I can't even imagine how insane it must be. I floored it
in 4th gear on a cold day and I was a little nervous about traction, lol. I'd need diapers in your car.

 

Rix- your car's performance is absolutely insane. Wow. And your shifting is phenomenal. Literally seems almost as fast as PDK! I am running a Protomotive twin disc set up and there's no way I can shift that fast.

Also- Are you still on your stock transmission, or have you built your trans?

 

i am very interested as well to know your clutch/flywheel/transmission set up to shift so quick and smooth?

Crazy machine you got there my friend!

 

It's a Tilton triple disc carbon/carbon. There are pictures in this thread if you scroll back far enough, and quite a bit of discussion about clutches in general. It's the Tilton that lets me shift like that. Especially the 4-5 and 5-6 shift. With the stock-ish (the usual Sachs upgrade) it was completely different. The Tilton releases lightning quick (and I think more completely) making it possible.

Trans is stock 997. I send it to Bill Rader this year and had him do everything he possibly can. There aren't actual upgraded gears even available unfortunately so I had to spend more for the gears I replaced than I would have buying aftermarket ones. It was frustrating but was really the only path forward because I didn't want to convert to a 996 box and build it with the upgraded gearset ($20k+).

Backing up, the reason I had to do this in the first place is because I hurt 5th and 6th gear in the trans. I think it happened at Texas Mile (Hit 227 in 6th gear at the 3/4 mile mark lol) but it may have been building up for a while.

Not sure if I posted these pics;





The reason 5th/6th got hurt according to Bill is that the gear oil in the trans was forced back by all the acceleration. From the factory it doesn't spray oil on 5th and 6th gears, so we added an additional spray bar that coats them. Steve from Driversource of course is aware of this and has developed a nice kit that adds the additional oil lines, a small oil pump, and makes the whole process turn-key. I'll see if I can dig up more info on this.

We also went ahead and replaced 3rd gear because it had served me well for 3 years, but it's the weakest in there. When you're spending that much money on the trans I just wanted to replace it as a preventative to avoid grenading it and having the parts tear up other things in the trans and end up with it broken again.

I went with a Wavetrac rear diff at the same time - that has really made a HUGE difference in terms of being able to put the power down in 1st/2nd/3rd. Still in the process of figuring out exactly how much I can do. I know it can probably put more power down in 2nd, I was at -19 (MINUS 19) degrees of ignition timing in 2nd gear to keep it from blowing the tires off. That number wasn't determined by me, it was the Syvecs torque management going out and getting the requested max torque.

Aside from that, Bill added his Billet diff side cover (I think it looks meaner than the California Motorsports one too), and his billet bearing clamping plate. He uses some different hardware/nuts/bolts and his proprietary assembly procedure. Basically, when you put big power through a factory assembled stock transmission the main nut tends to loosen up and then bad things happen. So if you're going to put some power through your trans the best thing to do really is to send it to Bill, have him check everything, and add what parts you can. Then you don't get whacked with $4k+ of parts alone to replace gears.

 

Thanks for the kind words!! I really enjoy running it and sharing videos and information about it. Thanks for making me smile .

I have had people come up to me and ask how I got a PDK in a 997 after seeing it run. It always gives me a good chuckle. "Yeah, the PDK lever wouldn't fit so we just kept the 6 speed trans shifter lever."

 

Here's a cool vid showing what it's like to be behind them on the runway. Todd (BHT), and me on the right.
