OnPoint Dyno and
friends are back at it, with ported Jenvey throttle bodies, header length
testing, carbon airboxes, and multiple intake trumpets - including 3D
printed trumpets courtesy of Jim Wolf Technology.

The STILLEN 500 HP Supercharged Nissan 370Z - /TUNED
TUNED Visits racing legend Steve Millen's STILLEN in Costa Mesa, CA to see
what happens when he gets his hands on the Nissan 370Z. Already a potent
machine, what happens when STILLEN upgrades pretty much everything?
Fortunately, it doesn't suck.

Nissan 370Z / G37 VQ37 VVEL camless intake valve system
Nissan's Variable Valve Event / Lift (VVEL) System currently used on the
370Z & G37, but will migrate to other models combined with in-cylinder
injection, turbocharger(s), & Exhaust cam phasers (not used on VQ37
currently). Also an explaination of the VVEL linkage adjustment that is
factory set and not to be touched (Nissan requires heads to be replaced if
adjustment is changed!) for performance engine builders developing VQ37
engines. For more info on this subject try:
This rig was built a couple of years back as part of a project to build the
3.7 engine for a race engine program. Since then we have built special Exhaust cams to match the high lift
intake settings but never used them in racing. Due to the unique offset in
the valve to cam centerlines that Nissan had to design into the heads to
accommodate the VVEL system, the peak velocity of any Exhaust cam profile will be limited by the
offset wipe pattern radius, which is even more basterdized by the fact that
the offset is on the opening side on one bank and closing side on the
other, a real cam designers nightmare! Currently we use earlier HR heads
that share the excellent coolant and gas flow paths, but with centered cam
to valve alignment, allowing for conventional racing cam profiles on intake
and Exhaust. VVEL for race engines may
have advantages, but there are some practical constraints that must be
372whp 350z, ITBs, Head Porting, Longtube Headers
This was the last day before SG was sadly closed. We got the ITBs just in
time, installed them and made them work despite missing all of the linkage
parts - tuned it and the result was incredible, over 30whp above our
already modified intake manifold and 90mm throttle body - that's 55whp more
than a factory throttle body and plenum. Read all about it, the head
porting, larger cams and injector dynamics injectors in Modified Magazine -
