What pulley combo are you running?

Hardly a cost advantage when you put it into perspective.

bottom line, the average s/c'd cl-s is gonna see my tail lights when it's time to race. this was proven during the WCM.
and when i said $500, i was including all the nitrous i've used since i installed the kit.

do i think that the nitrous is more enjoyable than a s/c? hell no. i just haven't had a bunch of extra money to put into a s/c.
my mods are paid for and i'm happy w/ what i have.

in no way am i implying that chaps or any other s/c cl-s is slow.
saying that i would have a shot at chap (no n2o) assumes that my experience would give me an advantage in the race. after he figured it out i would have to flip the switch to keep up.

Well I figured out that the revs fly much much faster to redline than before the S/C :captainobvious: It's still hard to judge that 2 -> 3 upshift. And I've noticed that if the transmission senses you are too high in the rpm band to make the shift it just won't do it. It'll stay in 2nd gear until you let off the gas, let the rpms fall and shift again. If you time the shift right or even a little early it'll shift just fine. But I can't shift 2 -> 3 in SS mode at 6900 rpm and think it'll make the shift before the rev limiter. I need to shift around 6500 rpm for it to shift right at 7100 rpm. I guess this is somewhat of a "safety" feature to not break the 2nd or 3rd gear teeth 
I haven't had a problem in D5 or D4 since the first night, just driver error in SS mode. Also, traction is non-existant in 1st gear after VTEC.

It has also happened to me before the S/C once or twice. It happened then while I was going down a hill. I think the "grade logic" feature of the transmission messes up high-rpm upshifts when you are on a steep downhill grade.

you kno what....my car does that as well...sort of
If I floor it through 1st into 2nd...and I decide to shift in 2nd rather quickly around like 3-4k rpms, instead of continuing all the way through 2nd into 3rd...it takes me 2-3 times to tap the shifter just to shift into 3rd.

i've never experienced it on the track either, only on the highway.
i have that same 1st gear traction problem you do. as soon as i go WOT in 1st i have to shift into 2nd and i still hit the rev limiter sometimes.

and i'm not saying you are a bad driver, it's just that cutting a light and launching at the track is something you only learn at the track. and i've done it ~ 150 times.
RedRider found that out last year at WCM '03. he had 0 track experience and i was able to run better times simply because i knew how to launch and squeeze the best times out of my car.
but when we lined up on the highway... well, you saw the videos.

the chances of something like that happening are 1 in a million.
we know that the true reason you won't take it to the strip is because you're anal about your car and you wouldn't want to risk hurting your baby. it's silly, but it's OK.

Fuel pressure pegs out when I go WOT and then slowly backs off to about 85psi by redline. I haven't heard any detonation.
Aside from the S/C's blower whine, the B-pipe has totally transformed the sound of the car. While in 2nd gear, if I let off the throttle at 6500 rpm the exhaust lets out this huge "burble" for lack of a better term.
I'll be taking it easy tomorrow and then hopefully i'll be off work in time for my dyno appointment Wednesday afternoon @ 4:30. 285whp would be more than pleasing, although I might dump some octane booster or 100+ octane in there to try and get a 300whp reading

We might just have different gauges that are reading differently. I have the Autometer Pro Comp.
Also, I only see 6psi in 1st and 2nd gear. For some reason I hit 7psi in 3rd gear. I'm swinging by the dealership tomorrow AM to have the belt tensioner tightened one last time.
I don't know why my vacuum is so low either... i was expecting it to be in the range you described. My fuel pressure is also lower than most, but I'm still running plenty rich as my dyno showed. My fuel pressure sits at 38 psi at idle when I first start up, but once I get moving it drops to around 35 psi or lower while crusing on the highway. When I go WOT it jumps to 98psi and falls back to just shy of 80 before redline.

Yes that one time you beat me,... not at the light, but at the 60' mark, (same thing?). I was seeing how far I could do a burn out, (about 50') and discovered that you could actualy get both tires spinning with the 5AT, as I drifted 15' to the left before I had to let off to avoid the wall,...then nailed it again and still caught you at the end, (almost).
