[QUOTE]Originally posted by 93PONY: [QB] Drew should've gained more like 20hp peak & 5-10 under the curve. You know the HP equation. Moving the torque curve higher in RPM's above 5252 will give more HP. It really depends on the initial curve on how much can be gained/lost with moving the valve-events. The problem that I see w/Drew's setup is the rev-limiter. Peak power moved from 5500 to ~6000-6100 I think. So, he went from shifting at 6000 to shifting as close to the rev-limiter as possible. Idealy, you want to shift 4-500rpm above your peak HP to give max MPH in the 1/4. With the stock rev-limiter, he'll never get there. Aside from that, on nearly every run he hits the limiter, which pulls fuel/timing....& doesn't it store tables & cause the car to go into 'limp' mode sometimes??? As for the tried & true combos....those H/C/I blower cars only putting out 450RWHP are weak. Better valve events alone would give more impressive results. Add faster ramp-rates, which means more .200 duration (were heads REALLY flow) & the power just keeps coming. As for the fastest cars around here.... You have said that it's pretty sad that there are so many slow HCI cars in Norcal. I agree. & like you said, not many custom ground cams around here. Most of these slow HCI cars are suffering from poor valve-events, intake air-charge & exhaust gasses stalling in the manifolds causing surging, etc. Mike Camara's GT ran as hard as those blower cars....w/an AFR/custom cam combo 347. Aaron's car was well over 400flywheel HP this time around....on a 306 w/AFR's & Mikes old cam. It got faster after you rode in it BTW. Added fuel & it responded quite well. [/QB][/QUOTE]
