To give you an idea, with the csu carb we had 72/87 jets to get a 12.0 a/f and driving on the street it had a lean spot just before the boost came in. Sometimes it would pop in the hat cause it was so lean. Kevin's brpv's use the boost to open.

Brents carb set-up uses the same carb but he makes his own brpv's and they open from a small air pump/rshared_pm switch. He also goes through the metering blocks better and they flow enough fuel to fix the lean spot. With the metering blocks working better and the brpv's opening with the pump our car was able to run 68/68 jets and 10.5 a/f. You have no idea how much better the car drives with the less jet, nice and clean.

With Kevin's carb if you put it up on the trans brake it would go way lean then rich (as soon as the boost came in) With Brent's it came up clean and we would set the brpv's to open just after you let go of the brake.

Brent charges 900 for the pump, rshared_pm switch, his brpv's and all the work. He also will help along the way and if you change your combo he will step up the carb for free.
