Cam Gear setting on a GTR RB26DETT

[meshmesh]

Guys,

just wondering if the following adjustable cam gear setting would be ok. "I dont know which of the these is IN or EX so just use your knowledge to work it out"

+4degrees & -6degrees

I'm a little concerne as I thought it was normally something like

+4degrees & -1degree

The car is stock, except for:

Exhaust from front to back

Bleed Valve

HKS Pods

Cam Gears

& Power FC

Thanks

Hmmmm, +4 and -6 seems a bit aggressive to me. As you said, most people with the basic mods seem to find +1 on the inlet and -4 on the exhaust the go.

But it does depend on your car.

I'd start at +1 and -4 and fiddle with them on the dyno from there.

I could be wrong on the settings, but I know they were mid rangfe power & that I would loose top end.

Yep, definately loose top end.

I tried some different cam settings on Dyno2003 software. the more advance on the inlet, the better the midrange, the more retard on the exhaust, the better the mid range.

I tried using -6 deg on the exhaust and it started killing power above 6000rpm. Advancing the inlet seems to bring power on earlier, but takes it away above 4500rpm (interesting I though, as this is where nissan swich off NVCS on RB25DET).

As mentioned, +1 on the inlet, and -4 on the exhaust seem to be the 'classic' settings for more midrange without killing top end too much.
