Hi guy's

i was just wondering how these cam's will go on my car and if i need to change anything to put them in and run them. They are 270 inlet 280 exhaust with 9.5 lift

are these cam's for top end power or to help with boost response cause i really want to come onto boost earlier attached is my dyno graph. what kind of improvements do you think i would see??

Too big, you will lose idle quality, and low down cylinder filling. Not a really good cam design, as for the same result, you would run more lift and less duration. This is a compromise so the head doesnt have to be modified. I would recommend 264's in and ex, or maybe a 272ex, you will probably only gain 30rwkw, as the turbos will hold you back

Or beer baron has some poncams that would work really well

forgetting that i'm selling cams, my opinion, in agreeance with Adriano, is that the cams you propose will be a bit big for N1s.

will be crap down low and want to idle at 1200, and too much overlap down low so won't help low end performace...

fyi with the poncams on garret 2860s mine made 340rwkw at 19psi...

yep, too much duration, not enough lift. buy my cams so I can fly to melbourne and punch ronin_09 in the nuts! lol.

I guess if they are really cheap you could give them a crack but there is a shit load of time and/or money in installing the cams, checking all of the valve clearances (and possibly replacing a lot of shims) just to find out that your cams have too much duration and not enough lift...

So? As has already been mentioned they are completely unsuitable for your application.

Tomei Type B Poncams would be the ideal choice, being a drop in cam that doesn't require any modification or machining of the head.

More to the point though, if you are chasing more power I suggest you start by reviewing your list of mods and directing more attention at other items that are restricting your engines potential, ie the fact you are running standard injectors.

I would be replacing the injectors with something along the lines of Sard 700's and getting a retune first and see what sort of results you can achieve, then look at adding some new cams down the line.
