Performance Camshafts Holden HSV Grange XU6 L67 3.8L V6 Supercharged VS VU VT VX
Revhigh performance camshafts for the supercharged L67 3.8L V6. Choose Stage 1, 2, 3 or 4 in the drop-down. Revhigh cams use custom designed lobes to maximise the performance of your supercharged engine.
Choose in the drop-down:
Stage: Stage 1 / Stage 2 / Stage 3 / Stage 4
What each stage is for:
Stage 1 Street: for totally stock heads and stock components up to 6k rpm. PCM programming is recommended. If the engine has less than 150k km the stock springs can work if you keep the shift point at 6000rpm, but we recommend at least 90# valve springs and retainers. 206/216 at .050 inch, intake lift .320 inch (.512 inch at 1.6:1), exhaust lift .317 inch (.507 inch), 115 LSA.
Stage 2 Nitro: for supercharged or nitrous applications on 1996 and later GM 3.8L. Look for gains of 40-55 hp depending on configuration. We recommend 136# Comp Cams valve springs, Revhigh modified retainers, LS7 lifters, 7.00 inch pushrods, a Rollmaster double timing chain, an extra thick front cover gasket and a machined oil pump cover. 212/224 at .050 inch, intake lift .325 inch (.520 inch), exhaust lift .335 inch (.536 inch), 116 lobe separation.
Stage 3 LOP: lopey idle, and lets you run small pulleys non-intercooled. Lots of overlap gives a slight loss in torque but allows smaller pulleys without knock retard. Usable with an intercooler and on stock heads. Needs at least 125# springs, modified retainers, LS7 lifters, 7.00 inch pushrods, a Rollmaster double timing chain, an extra thick front cover gasket, a machined oil pump cover and PCM programming. Use a Revhigh STG 3 tune or wideband on the dyno. 220/230 at .050 inch, intake and exhaust lift .317 inch (.507 inch), 112 lobe separation.
Stage 4 REVHIGHX: developed by Revhigh to maximise the power of a supercharged 3.8L with an M90 blower in an all-out build, with aggressive ramp rates and high lift (.570 inch). Needs ported heads with machined valve guides, at least 136# Comp Cams or 150# springs, modified retainers, LS7 lifters, 7.05 / 7.00 inch pushrods, a Rollmaster double timing chain, an extra thick front cover gasket, a machined oil pump cover and PCM programming. A supercharged 3.8L with this cam holds M90 power records at 460 WHP+. Idle is similar to Stage 2 with 13 inches of vacuum.
