It was cool meeting some of you in person at McDonalds. Hopefully I can make it out to some more get togethers. I wasn't expecting any turbo buicks to be there at all so it was a pleasant surprise to see so many.
On my way home I got a little lost and ended up on what I think was Anaheim blvd? anyway, along comes this terminator cobra out of nowhere and starts pacing me. So I decide to give him a little taste of boost and get on it for a second. He then decides he wants to run. I hear him drop down a couple of gears and start hearing the supercharger whine so I get on it again and it's on. This thing was surprisingly fast. I right off pulled a half car on him and was creeping up on a full car when we had to let off. We only got on it briefly. Turns out his passenger was video taping the whole thing. We then went to the freeway and they tried to run me from like a 65 mph roll. I was surprised to find out that I was killin' em worse there. Every time we took off I immediately put a couple cars on him. The guy said he would post the video on streetfire so I'm pretty excited about seeing it.
It was probably one of the faster cars I've raced on the street. Normally nothing I've ever run into has given me even a close to decent run. I'm wondering what he had done to it. Def. had a lot of supercharger whine+ exhaust at a minimum
BTW we had talked about WB sensor placement.. here is some info for you:
Support :: Innovate Motorsports
"The Bosch LSU4.2 wide-band O2 sensor (shipped as part of the LM-1 kit) is rated to operate at an exhaust gas temperature of < 1300 degrees (F), and a sensor housing temperature of < 900 degrees (measured at the bung) for maximum accuracy and control. When either of these operating temperature ranges is exceeded, the sensor can no longer be accurately controlled. Further, operating at or over these temperatures for any length of time can significantly reduce the lifetime of the sensor"
as for plumbing your wideband pre-turbo
"On a n/a engine you will not see any back-pressure high enough to influence the readings appreciably with the ST-12 and Bosch sensor (NTK is different). The "excessive" backpressure warning is for people wanting the sensor before a turbo. There you would have backpressures up to 2 times boost. Depending on AFR, it can cause up to 1 AFR difference at very rich AFRs. The error will be larger, the more the AFR differs from stoich." - innovatemotorsports site administrator
Measuring 1600+ pre turbo in the stock o2 bung is pretty common. I think post turbo temps dont come down that much more till you get a good ways down the down pipe. Thats why I have my wb mounted at the end of the downpipe.
Your results may vary, just sharing what the sensor limits are and what works for me.

I love the "street tires" you're rolling around on :biggrin:
