The Quick and Easy, Cheap and Sleazy results of the meet, as told by me.
Nobody remembered to bring a camera this Time around. Roger even has a digital camera to take pictures with but forgot to bring it. We won't hold it against him because we all suck...
Ok, I now have the wav files and dyno runs available of the various cars. Go the bottom of the 2nd meet section for the runs and wav files.
Attendees in order of appearance:
I showed up at the dyno shop at roughly 8:45 am. Nobody was there yet I made brief arrangements to have my ACT stage 2 clutch installed on Monday morning. At 8:59 am, Robert pulled in. Five minutes later, Ken showed up. I had my car up on the dyno when Alex finally appeared. Shortly after that Daven and Roger walked in together.
After finishing up our dyno runs, we headed down to Mimi's cafe less than two miles from the shop. We hoped that a couple more people would show up (maybe expecting Mary and Joe) but it was just the six of us. We spent some Time discussing various things (as usual) such as tickets, maintenance, the next meet, more mods, etc... The usual car stuff and swapping war stories. Several of us are planning to head over to Pomona on the 5th to do some "test and tune" drag racing, so if anyone else wants to go, we'll definitely discuss it.
Fun was had by all who attended and we hope to see more people show up for the next one. Maybe someone will even bring a camera... :)

I opted to test that Tornado Air management device once again. I had planned on NOT dynoing my car, but since the ACT stage 2 clutch is sitting in my trunk, I figured what the heck. First pull was made with the Tornado Air intake in place. The second run was done without it. Up to about 5000 rpm there was very little difference between the two pulls, but above 5500 or so, the Tornado clearly demonstrated to create drag and HP was lower than the pull without it.
Robert made three pulls today. The first was made with a Greddy exhaust and a Hotshot intake. The numbers he posted were VERY high and I was actually pretty surprised at how well his car
performed. His second run was performed with the Hotshot removed and the stock airbox in place. Still, the car made an impressive showing. He made one more run with the Hotshot bolted back on. The results were really surprising. He pulled out a peak HP of (corrected, smoothed) 148.8 vs. my best of 147.5 that day. Without the dyno charts, it's hard to explain, but let's just say that the Greddy seems to have made a big difference and beat me even when I had the headers on. Mind you we won't know how big of a difference this can make unless Robert gets headers, but it definitely surprised me.
Ken was the only one powered by nitrous today. His mods consist of a custom exhaust and a dryer hose fitted to his stock airbox. His first run was normally aspirated. Power was just
about average for a probe (he had about 131 hp) but his torque was in the 137 lb-ft range, which is pretty high. The numbers generated seem to indicate that his setup doesn't seem to yield much more average power than a stock car despite the Hotshot Gen 1 headers, ram air and exhaust. Once the NOS was fired up, things changed a bit. The bottle was somewhere south of optimal (below 900 psi) when he made his run. When he pulled into the bay we all started laughing because his bottle was in plain view through the glass ("man, you've got guts to drive around like that"). That is, until he reminded us that we had suggested that he expose his bottle to warm it up. doh. We made a lot of blunders that day... Anyway, on the bottle he made about 185 HP and 199 lb-ft., the equivalent of a good 50-shot,
I guess. He said with the bottle up to 1400 (!!) psi, he could beat Trans Ams. I believe him. He's a madman.
Alex has the backwards rims on his rear tires. Sorry man, couldn't resist. His main mod is an RS Akimoto filter with the s-shaped stock intake tube in place, which effectively has it
blowing cold air onto the filter when he's driving around. Also, his car has an exhaust leak which gives him a rather distinctive sound. His second run was made with the stock airbox put back on. Interestingly enough, below 5000 rpm the car made more torque with the stock airbox, but above 5000 the Akimoto had the power edge. There was a definitely spike in power at the 5000 rpm point, which leads me to believe that those who make this mod and say they can "feel a surge" in power may be because they're giving up a bit in the beginning to gain a bit in the end and the transition point is dramatic
rather than subtle, making one believe that the car is significantly faster. A strong psychological influence backed up by a false physical feeling. For Alex's third run, we bolted the Tornado Air intake into his car, just for kicks. His car is otherwise stock. The Tornado run showed a drop of about 3 HP below the first stock airbox run. This seems to really seal the fate for the Tornado in our cars, there is no power gain and rather a loss with the Tornado attached to a Probe GT V6.
Roger's mods are identical to Robert's mods. I think there's a difference in the fluids used, but I'm not positive without my notebook. Again, I'll have to wait until Monday to get my data. He just ran his car twice on the dyno, back to back, to determine the Dynojet dyno's repeatability. Back to back, the HP varied by about half a horse and torque was off only by 1 lb-ft. The curves were otherwise nearly identical. His power output was roughly 146.4 HP, which places him right in reach of Robert and myself. With just one car doing this I would have considered it a fluke, but with two this seems to indicated that the Greddy is definitely (not just marginally) superior to the Borla exhaust in the power department. They pretty much smacked my car down at all power ranges, except for the peak torque point +/- 250 rpm. And neither of them have headers. Scary.
