1914cc, 8:1 comp., c45, 40x37 mofoco heads slightly ported, 40 dcoe w/ air bypass ports aND velocity stacks. tried 53, 55, 60 idles.... 63 idles responds right now. I added a fourth .80 progression hole to carb that took the flat spot out when you stab it. Only 30 venturis but pulls past 6500 rpm quickly. F11 emulsion tubes, one w/175 air-175 gas. Other w/170air-170 gas. 2.50 n/s set at 1.75 lb....boost referenced holley fpr does the rest. Also, I just put a light coat of wd40 on air filter. Other oil that i had for air filter element caused an intake restriction in mid to upper rpms.

40 dcoe flows way more fuel than I need. .. Madmike...make sure your float is not set too high because on boost your 3.00 n/s can be overridden causing over rich condition. More tweeks and fuel tuning with side drafts for sure, but they are awesome in performance.

Racerx128..... no times on my bug, just a hobby. Madmike should have some times.

Check pump jets size.... I've seen them opened way too big. (1.10, 1.15)..... 70 p/jets are a good start.... You might need 65 idle jets for off the line responce.. ..try 175 on main gas and small increments up as needed. Engine will pull strong without a hickup once enough fuel is supplied. I'm at around 700' elevation
