See the bottom of the other dyno thread for some of the results from our runs this weekend (click here).
Thought I'd post these before I flew out of town and lost my high speed internet. Had a fun meet in Charlotte this weekend (even though I had to work (on phone) for half of it) with Dex, Bitkahuna, Dr Rick, Krista (my GF), Avery (Dr Rick's bud with 1st gen GS) and Shawn (YellowIS).
I'll find a better way to host these so they launch better later, and there are more/better videos coming from Dr Rick. These are 15 sec short clips from my Sony digital camera with some of our cars on the dyno.
Click here for an index of short dyno videos. Best way to access them if they don't launch immediately is to right click and select open in new window.
Dr Rick's cool green GS is on the dyno and is missing from the pic below. BTW, that little white Ford Focus beside my car has 302 RWHP (turbo and nitrous).

Muchos gracias, Dave! Hopefully those videos give people an idea of just how freaking loud it was in there. ![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
Think that's FWHP.

Yeah you guys are lucky...is wish I could have been the one dynoing my car, I would have got more horses out of it...

Yeah yeah, I know its FWHP. One little mistake and everybody jumps on you. Jeez!

I could have sworn he said it had some funny gas in it... it had a cool little Greddy button installed on the wheel - what was that for?
Rick - the look of concentration on your face in that pic is worth at least 10 ft lbs of torque in my book.

You should definitely have come up and introduced yourself as a fellow CL member!!! I did introduce myself to Rick and asked him if you guys were part of a club. Once he told me you were members of this club, I told him I was also a member of this club and pointed to my RX300.
Yours is the blue Focus that had a blown engine due to a cheap turbo kit? Yeah, my focus is majorly screwed up right now, but give me a few months and it will be stomping some serious ***.
We would have talked you into putting your RX up on the dyno too!
That's funny that you mentioned that, because once we had that damn u-haul tow dolley and focus off of the back of the rx300, my wife said "you should have put this on the dyno."

That little yellow Greddy button on the steering wheel is how he switches from low boost to high boost.

Standing there and watching/listening to your GS's dyno was pretty cool. I was wondering why the guy with the huge *** Lowenhart wheels, didn't put the stock ones back on for the dyno runs. Those wheels have to weigh a ton compared to the stock wheels, and that's more rotational mass which means more loss from crank HP to wheel HP.

Anyway, I have heard the theory about unsprung weight and rotational mass as it affects hp & tq, although a little muddy, so I asked Tony about it, and in not so many words, he dismissed the notion about lighter wheels affecting hp output, so, I didn't push him on it.
He quoted from experience where several guys had invested in lightweight this and that, especially wheels, then re-dynoed, only to see very meager gains in output numbers, if at all. So, either he didn't believe in the theory, or didn't understand it.
If you understand it enough to fully explain, I'd love a quick lesson.

That being said, even if the OEM 17s would have given me better numbers, it would not have mattered much to me. I don't run 17s on the street, and would want a true representation of output per street variables. When leads me to my personal theory about prepping for output tests..........
Kinda like bench racing, or gutting your car to get a great time; I want to have real world criteria built into the mix, instead of having to say, yeah, well, if I had my 17s on, I'd tax that *** like the IRS, or, yeah, well, hold on dude, let me take out my spare, lower the air in my tires, get some race gas, and meet me back here in a couple of hours......
Hey, I [b]do[/i] want the best times and outputs, I just want them to be representative of what I can duplicate on the street. Its kinda like be an All-American on the driving range, then you can't keep it in front of you on the course.

I'm more intersted in what my car will do as I leave my carport with no prep; no false sense of confidence i.e. everyday status.

I can see your point of view, but for me, I'd rather have the lightest tires/rims on the car for the dyno and at the strip. It also has something to do with bragging rights I guess. When I enter my car in a car show I can post the highest dyno results and lowest 1/4 mile times I have regardless of what tires/rims I used to get them.
I really don't know everything about the dynamics of why you create more HP with lighter wheels and tires, I just know it has to do with the inertia needed to get those tires moving. How much do those "huge ***" Lowenhart wheels weigh anyways? Those were 19s right?

Weights: The R: 19x9.5s = 28.5
F: 18x8.5 = 27.3
Thanks Dennis @ Wheel Kinetics for the info!
So, yep, a little on the heavy.

And it's not just rim weight, but also tire weight - your 275/35-19s probably weigh a good bit more than a stock 235/45-17.
I'm not convinced heavy rims/tires would affect RWHP as we discussed Dex, but I can see how it would affect torque because you basically need more torque to move (twist) a heavier mass.
