Paul, my boost gauge, as well as John'* (the two you're most familiar with) have always SNAPPED into boost. Even Pdad was stunned in 2004. I have no loose TC. Trust me, I'd know. There are two important notes to make here:
1. Mine snaps into boost more quickly than any other Series 1 partially due to the extra idler. I gained much better power through the midrange. I was getting belt slip during accelleration (not at WOT, but on the way there). I get much better boost response during accelleration now, simply because of the improved belt wrap. This is true with both Gates and GoodYear belts. Please note that ALL Series 1'* have belt slip with a 2.2" pulley and a brand new tensioner and either brand of belt. I can link you to the topic if you like. The belt path is very different on the S2, and it was re-engineered for this reason. I gaurantee it.
2. Let'* also remember that my intercooler design is quite different than the commercial offerings. I RETAIN my boost/vacuum source inside the manifold, and it doesn't have to go through the core of the intercooler. It bypases it altogether. In addition, my core has greater flow area (less restriction) as it'* wider and a little longer than a S2, but not as thick. I also have 'overflow' protection at each end so that if the boost builds quickly or is affected by the core, it will simply bypass the core altogether to keep pressures in line.
Dirthead, if you think this is some kind of tag-team scam, you're a fool. Too many people here know and drive my car personally several times a year, and all of them are familiar with other Series 1'* on the West Coast. God knows I have a reputation for lying and faking **** on my cars. That whole thing last year at Woodburn dragstrip where I was ripping 1.9 sixty-foots side-by-side with a 12-second GTP? Faked, obviously. PDXGTP is in on the scam also. Yes, my car freaked him out as well. Why? He wasn't familiar with how different of a beast the S1 really is. Those unfamiliar with them simply classify them in their minds as 'inferior and the older type' when in reality, they just shine in a different way. The two types were designed for two very different reasons.
This isn't some kind of scam. It'* an answer to the question you asked about why the S1 has stronger bottom end grunt than the S2 (and falls on it'* face at the top end). I suggest you go drive one for yourself.
As I stated before, I used to have the curves, as we all did 'back in the day' here, but they are no longer posted on GM'* drivetrain site. Rather than calling this a tag-team scam, maybe you should spend the time to find the curves for yourself.
