280cams+valves, retainers or go with 272s and stock???
Hey guys, I cant decide whether to dish out the extra dough for the supertech valve springs and retainers for my hks 280cams or sell the 280s and go with 272s with stock valves and springs.
Ive got a 35R kit sitting and waiting and I want to do it right. I dont want to overdoit either (and save $$$!) for a car with a stock block. I wont have the dough to build the engine for a while
Ive already got the hks 280cams sitting in my room

Bolt on the HKS 280's
keep stock rev limiter
+ bigger injectors if you dont already have them...
and when you have the money build the motor and put in some Valve Springs & Retainers then you can rev it out to 8500-9000rpm...

hks 280s are not that aggresive of a cam. the kelford 272s are a more aggresive cam then hks 280. i know someone who has 280s on his car with the stock springs and retainers and everything works completely fine. he drag races the car and everything. so no driving the car hard with those cams and stock springs and retainers will not hurt it at all
Audi2Evo, be careful of what you read in here. It's easy for anyone to come on here and talk about cam A is not a good street cam (whatever that means), Cam B is the shizzle, Cam C ... you get the idea.
I just got my car retuned at AMS and, as usual, they have been kind enough to give me my dyno runfiles. I've attached my last run with the HKS 280 cams (set to +2i, 0e) and the first run of the Kelford 272 cams (also set to +2i, 0e). No change of tune. All AMS did was drop in the new cams and put the car onto the dyno. I believe this should answer most questions in regards to how the HKS 280 is versus the Kelford 272.
A couple of things to keep in mind:
1. The runs were done on a 93 octane map (AEM EMS) and ~23psi boost
2. The 50 trim on my car is clearly overmatched by about 8000 RPM
I will post the final tune (100 oct, 28 psi, 0,0 camgear timing) in a separate thread, where I will also post cam timing results for the Kelfords.

Just keep in mind that the comparison isn't apples to apples as HKS and Kelford are ground on different lobe centerlines, and you are most likely reducing power by running that Kelford intake cam at such an advanced setting. An HKS intake cam at +2 is about like a Kelford intake cam set at 0.

... but if anything, the car sounds more pissed off than ever.
