Did you get the buckets replace with a different size due to the increase in duration of the cams? This has to be done so the valve doesn't hit the piston. I have the JUN cams and have no problems. These are not just drop in cams. You don't have to get a retune right away because JUN made these cams to run on the stock program so that's not your problem. You really need to make sue the intake side is still in factory spec with the VVEL actuators. Go to the dealership there and tell them you need the VVEL actuators reset to factory cause there is a long procedure they have to do in order to reset it. I was there for my entire build so if any other questions please ask

WERT? You mean checking the clearance between the cam and the follower and changing to a different thickness lifter to adjust any that are out right? and this is due to the base circle being cut down on the reground cams. Man if you had it done at the stealer I would hate to know what you paid, the vvel reset is easy enough and can be done without consult 3 the stealer probably charged like 150-200 for just that.

Yes 272 and 282 . And mine is 282

1slow370 · 05-30-2014, 11:27 AM

when you did the cam instal did you check the clearance between the cams and the lifters?

Do you have the factory service manual?

elia_ebyss · 05-30-2014, 11:53 AM

Ctd-germany have a dyno graph for jun camshaft with mods : K1 rods , NST pully , AT flax plate , ss304 wrapped headers , 300 cpi sport catalyst convertor , Akrapovic cbe and stillen gen III

1slow370 · 05-30-2014, 01:25 PM

just to translate the above with correct conversions it is 389HP at 7450rpm and 292lb/ft at 5250rpm

In the page of the dyno graph say if they raise rpm to 8000 then the horse reach 400whp , also the tq is great number for NA cars

The stillen sc have 370whp on dyno and this na have 389whp without raising the rpm

I agree with na of course

1slow370 · 05-30-2014, 02:02 PM

stillen supercharger with garbage tune = 370whp

and they are good numbers im just saying the conversion in big red letters is wrong.

brucelidat · 05-30-2014, 03:24 PM

wow, those numbers are great if they're real. How much should one expect to pay to have cams pistons, and rods installed?

I am skeptical of those numbers though. What gas is he running, e85?

How come the HP and torque lines cross at 7100 rpm? Am I reading that wrong? Shouldn't they cross at 5252?

SS_Firehawk · 05-30-2014, 04:00 PM

Torque reading is in nm, not lb ft.
They are running 12.3:1 too... They have to be running e85.
