Built 2.0, Headgames head, kelford 272... -20

 

stock engine, kelford 272's @ -10...idle is at 1000rpm...

this seems to be the norm for people with these cams on stock engine?

should i be pulling more than -10 vac at idle? a couple people have told me i should get at least -15...but reading this thread sorta has me re-assured that i should be in the clear with my -10...

 

anyone?

 

Gsc2 at around -15

 

Crower 272's 18 inches of vacuum.

 

-10 comp 280 cams. Stock was about -18

 

IX stock motor S2's idle at 1000rpm pulling about -12in/hg

 

old
hks 272's at -18

new
gsc s2's
map sensor reads -7
boost gauge reads -11

im assuming map sensor is more accurate?

stock 2.0, gears set at -2,-2

 

mivec cosworth m2's idle around -6psi

 

evo 9
stock cams
800 rpms
-16 psi vacuum

 

evo 8
stock longblock
kelford 272s
idle around 1050

-11

 

mivec cosworth m2's and i'm @-10, this seems like a slight issue bc when the vacuum is high my braking is better

 

same as last two kelford 272's around 10-12

 

Kelford 280's between 9&10 @ 900 rpms

 

kelford 272s, unported head, -11
