I have just checked Batman's compcam boxes, they are 8758 and 8759 - which were supposed to be stage 2 LSJ cams.

 

ZZP need to alter their website as these clearly state 210/212, not 216/218.

 

ps: Joe you need new cams, these are too mild for a Harrop

[color=#000000;][font="arial, sans-serif;"]Ok, well I don't see any problems.  8758/8759 are our supercharged stage 2 lobes.  I don't see anything that would suggest otherwis[/color][/font]

[color=#000000;][font="arial, sans-serif;"][color=#000000;][font="arial, sans-serif;"]Martin- what specs are you comparing that lead you to believe that these are not the right cams?  Based on the numbers you sent in your email below, you have stage 2 supercharged LSJ[/color][/color][/font][/font]

 

 

 

[color=#000000;][font="arial, sans-serif;"]So is it now agreed I have the right stage 2 cams???[/color][/font]

their website lists a cam spec, they have not supplied that spec

If mine don't come as advertised on there spec I will be kicking off very aggressively!!!!!!!!

[vocky]

perhaps I'm being stupid, well my brain does feel totally fried, but they quote a spec and when you check that spec it doesn't match does it 

 

It may well be that they changed the spec and didn't alter their website, either way something doesn't seem to add up 

 

However, if they produce the bhp expected then they are fine

Did you check at what liftheight ZZP specs their cams??

even that doesn't match Compcams spec sheet.

 

I think people need to run their engines on a rolling road and see what bhp they get, none of the numbers match and thus it's difficult to understand exactly what spec they really are.

[color=#000000;][font="arial, sans-serif;"][color=#000000;][font="arial, sans-serif;"]On your site it states that stage 2 for supercharged cars are -   ZZP S2 is 216/218 @ 1mm and 10.78mm/10.69mm lift, 111 LSA (216 is 8760, 218 is 8761) where as I have 8758 and 8759.[/color][/color][/font][/font]

 

 

 

[color=#000000;][font="arial, sans-serif;"]Oh, I see the confusion.  You are comparing different specs.  On our site, we have the duration listed at 1mm lift, which is the way that GM measures the stock cams.  Comp does not show duration at 1mm lift.  They show duration at .050".  Since 1mm is only .039", the duration is a few degrees higher when using this method.  If you look at the chart you posted, you will see they have duration specs at .006", .050", and .200".  If you added in another column showing duration at .039", you can see that the duration would be higher than it is at .050".  In this case, it is about 6 degrees more at .039"(1mm).[/color][/font]

well whatever was left of my brain just left the building   

 

I thought we were talking about duration not lift, but they may alter each other

Lets leave batmans thread alone and post here

[CHILL Gone DUTCH]

it looks like the stage 2 cams we have all bought are

  

inlet         @ 0.039 (1mm) = 216    and @ 0.5  =  163.8

exhaust    @ 0,039 (1mm)= 218 .  and @ 0,5 =  165.3

 

does anyone have the specs of standard z22se cams

In English,

 

zzp are saying that their stage 2 LSJ cams have different specs than those posted on the compcams website, whether that means they are just as good as blower cams will be proven once someone puts their car on a rolling road.

 

So don't panic

They have given the duration at 1mm 0.39" not at .50" so there site would seem to be correct and you have got there stage 2 cams. These may be milder than the comp blower cams but that is a separate discussion.

[CHILL Gone DUTCH]

im just hoping there not as mild as my z22se cams

[vocky]

which are 244 degree cams and really shite, which makes the stage 1 LSJ cams look brilliant
