[QUOTE="99svtvert, post: 5529780, member: 22962"] I have finished the install on my FR500 HCI 99 Cobra. Includes new springs and SFI Balancer. Engine acutally quieter than stock hydraulic lifters (adjusters) (so far). Exhaust is noticibaly louder (more crackle and snap). Put 250 miles on it; then Dyno Test. Initial Dyno; no re-tune; I will Post pictures and dyno charts later in the week. Initial Dyno: Max RWHP (DynoJet) @ 8150 RPM 433.1 RWHP (+24 RWHP change) - still making power with FR500 HCI. Near constant safe A/FR. Max RWHP (DynoJet) @ 7500 RPM 422.2 RWHP (+13 RWHP change) No real torque changes (+5 RWTQ) Max. Do you think a new dyno tune will raise these numbers at all ? [/QUOTE]
