280 Cams Installed !!!!!! Wow !!!
buschur put them in and lost no low end power and gained 15 hp over the 272's. This is on stock turbo on pump gas with aem standalone. If he gained 15whp and had no low end losses I see no reason why not to get these other then idle issues, but with cam gears and a reflash i tihnk that can be solved pretty good

Any cam set that gives longer overlap will result in less vacuum at low speeds and soften low speed response. This is just a basic fact, and it doesn't change.
There are things that can be done with respect to fuel and spark curves at low speeds that will improve low speed response of a lopey cam set. Furthermore, some of the overlap can be dialed out with adjustable gears, which tends to tighten things up and usually increases peak power, albeit at the expense of a little spool time.
In any case, it is reasonable to assume that the low speed response of the HKS 264 cam set can be made to be as good or at least as good as the factory cam set. The HKS 264 set doesn't present much overlap, so adverse low speed response really isn't much of an issue with that set. Besides, you'll really appreciate the bump in midrange torque, which you'll have no trouble noticing.
I hope you feel better.

he gained 15whp with no tuning and then 24whp with tuning over the 272s actually

the important thing is what you plan for the cams in the future. btw cams don't need to be broken in persey, there are precautions that need to be taken when you first run them. everyone should be using hte proper lubing when installing and stuff but there are mistakes and tolerances on everything so you need to not go hard on it until everything is oiled up by the natural means. if you bled the lifters then you need to wait for those to get oil/pressure back in them etc.
now back to what you plan for you cams. the 264s will not flow for anything more than the stock turbo, maybe not even a 20g. as in.. .the cams will be the bottleneck.
272 will flow lots and you can slap 272 on stock turbo car nad see the gains with un noticeable losses or just get gains all around depending on the tune etc. driveablility... if you're worried about this... you either get a stand alone or you don't get cams. stock turbo will not begin to exploit the flow capacity of hte 272s, gt40 is running a built head (which requires more flow) and a 3052r and it's serving him well.
280... i can only suspect that the numbers will be better than the 272 but once again you need to properly size it.. the flow is there... are you using it? that's the question. once again you can slap them on a stock turbo car... it might get you more lope and maybe a lil more lag... are you willing to deal? if you have the proper setup... you could see all the benefits without the losses... ti's about what you have planned for them.

i have the 272 cams and there very streetable. i also have alot more mods but still its very streetable maby i will swap mine out for the 280s oooooooooo that meens 272 hks cams up for grabs maby $250 for the pair. so fare i got header, turbo back, intake, fmic, piping, bov, cams, springs, valves, retainers, cluch, flywheel, ported head work, aem ems, 880 injectors, 255lph fuel pump, fuel rail, wide band 02, boost controller, running 22psi, stuck bodom end, stock turbo, and a few other things running 11.46 tuned by turbo trix.
