Project 350Z- Testing Jim Wolf Technology C2 Camshafts

The lower intake manifold, hoses and wire harness are all put back in place.  Again, this is a good time to inspect, repair and replace marginal stuff on high mileage cars.

The top of the intake manifold, air intake and all the little small stuff are now buttoned down.  The crank case is refilled with Motul 10w30 300V synthetic oil.

350Z cooling systems are notoriously hard to bleed.  Howard used a Snap-On vacuum bleeder to get most of the air out of the car's cooling system.  Once the system was bled it was time to dyno!

We let the car sit for a bit for all of the sealer to cure then strapped Project 350Z to our Superflow Dyno.

With the JWT C2 cams in place, our Z produced 239.5 whp @6600 rpm and 210.5 lb/ft of torque @5100 rpm.  This is an impressive 13.3 hp  and 5 lb ft of torque gain.  The cams lost power below 4400 rpm, as much as 6 wheel hp.  We think we can gain much of this back later with some ECU tuning.  The car did gain a lot of useful power under the curve and the cams changed the engine's character and made it a lot more fun to drive.  The car feels very eager to rev.  With the cams the engine's rev limiter needs to be raised as we were bumping it a lot.  The cams changed the engines sound a lot and it now sounds like a Ferrari!  Our dyno is very conservative so the overall power might seem low compared to let's say a Dynojet but remember the important part is before and after power.

Our power gains from the beginning.  We have gained almost 35 whp and 15 lb/ft of torque just from simple bolt ons.  We have more to go.  Our goal is 40 hp and we have a few more tricks to try.
