Hi everyone,<BR>I just wanted to jump in here and clear up a couple of things. Spencer was kind enough to join us at the dyno last weekend, while we were tuning another car on the dyno. We took the opportunity to tune his car on the dyno, as we have not done any s60 tuning up to this point. We were curious how much room there was for performance gains with our 91 octane fuel here in California. We were quite happy with the result given the huge gain of power across the rpm band. This program should significantly improve passing power and 0-60 times. <P>As far as the testing paramaters...<BR>1. Hot runs - Both runs (the stock and chipped) were hot. Cold runs would have exagerated the HP, and we need our claims to be reproduceable.<P>2. 3 hour window - All testing was completed within a narrow window to minimize day to day variations(barametric pressure, temperature, bad tank of fuel, overfilling the oil....)<P>3. 91 Octane - The best that can be purchased from the pump in California. Unfortunately, we do not have the pleasure of the 98 RON octane in Europe, which would definitely increase motor hp.<P>4. SAE HP- This is the HP standard of measurement used in the US. DIN is used by most European sources, and gives higher nominal value than SAE. So 247HP in the US would be 250.5 in most European countries.<P>5. Automatic transmission - These cars always dyno MUCH lower than manual transmission cars. Most Automatic Transmissions, like Spencer's car, lose 17% to 25% HP to the wheels as parasitic losses(heat).<P>6. 248C Dynojet - Different dyno's always dyno differently. Most 248C Dyno's give similar results, but other manufacturers' will be different. You also cannot fudge the correction factors like some other models to increase you numbers.<P>7. Delta - This is more important than any specific number. What is more important is the change from baseline. Even more imortant than a momentary spike in power, is to have substancial gains throughout the area under the curve. <P>8. X-Chip - This is definitely the level one program, designed to be very safe for the longterm of a T5's engine life. The next step will be a highboost version, which will probably be followed by one designed for racegas.<P>On the subject of performance claims, we are a little confused? We just decided to work on the S60 when we met Spencer, this last week. In fact, when Spencer was deciding whether or not to chip his car, he asked me several times how much we could get out of the chip. We replied that we wouldn't know until we tried. Now that we have entered into a distribution relationship with Eurosport Accessories, in Anaheim, we will have the oportunity to fully develop software for the Volvo market, as we have for the Audi, Porsche, and VW markets<P>Follow the link below to Spenser's dyno plot(2001 CA spec T5 s60). <BR> <A HREF="http://www.giacusa.com/volvo/volvos60.jpg" TARGET=_blank>http://www.giacusa.com/volvo/volvos60.jpg</A> <P>Thanks,<BR>Andrew<BR>GIAC
