Hows your idle HiBoost?
In theory the idea of zero overlap and wide lsa should work but in practise all of the big hitters seem to be running agressive profiles with a fair ammount of overlap.

Just look at ebs_4l. His sure cam grind bordered on lumpy as f**k and he spat out 513kw on a dyna pack (axle dyno)
Again Fritz, Dev 5a, lumpy as f**k NA cam making insane power in a turbo application.

Fritz, do surecam do regrinds or just billets? With the billet shortage I'm looking at a custom regrind for my turbo motor. The off the shelf regrinds are rather quite tame, even for turbo specific cams.

dev5 is not 'lumpy as f**k'.
it runs fine on an untuned factory ECU which should give you a clue as to just how agressive it is...

the cam is lumpy but with fine tuning it would be a smooth idle. i love my lumpy idles an thats what i got. they have many different cams for different needs.

yeh as steady ed said, the dev 5 is not a large cam at all... it idles no diffrent that a standarad cam would... but it does work very very well with turbo..

sure cam will do billet as well as re-grind, he will pretty much do wat ever u want...

Depends on what your after. Huge power and poor streetability or moderate power and excellent streetability.

Big power requires an aggressive camshaft with lots of duration and overlap.
Moderate power requires a much closer to stock profile.

EBXR8240 is spot on. Wide LSA 114, no overlap.

Some of the best streetable gains, can just be from big lift and similar to standard durations. ie regrind.

Remember that 0.020" lift duration determines idle quality, 0.050" determines approx torque rpm, 0.200/0.500" lift determines area under the curve and therefore power/airflow capability.

Have a look at the lift specs in the spreadsheet. It is 0.592" of lift! Thats about 30% more than stock! No wonder they require new valve springs... But the profile is much like a stocker which is why they could get away with running a stock ecu.

Still, 175rwkw n/a with a ported head is solid. There is a some guys over at FordForums which have that power - tested on an independant dyno too - running the JMM gear.

Atomic got back about a billet cam today. Part number is 306590 which they claim to have sold a number of for turbo/blown SOHC Falcons. Cost is $420.

Specs
Inlet duration 218 degrees @ .050”
Exhaust duration 220 degrees @ .050”
Lobe centres 112
Lift .510”

that spreadsheet calls it a Dev3...
i think whoever measured that needs a new dial indicator!!!
