How to get 300whp+ on a HR

If you had aftermarket headers you wouldn't be saying that! 
The stillen headers are far more equal in length then the stock HR headers with an increased tube diameter. I also took some time to file smooth the welds on the collector's and slightly enlarged and smoothed the exhuast ports on the headers. Whether or not this helped any?! lol Who knows! But I took a couple hours to perfect the quality of their product in my eyes.

Something is amiss!

You, phenom and one more that I can't think of (aside from A.H and I won't even get started on that garbage) were all tuned at that magic dyno in NY. You made like 26X on a dynapack and with the same mods baselined ~310 on this dyno. Come on now.

Just worry about gains people. Or go to the track and see if your lap times get any better. Personally I'm tired of reading the same dyno arguments over and over. Please just list the mods you have done and their gains so that people that are not quite done with bolt ons can benefit from your experience. I would really appreciate it since i'm working on that myself.

I also don't want the car to run like crap on the street. I have no intensions of making my Nismo a drag car. So I figured it would be best to stay away from that agressive of a cam. Its my hopes not to sacrifice anymore low to Midrange power. If I have to, then I need to decide how much is acceptable. I haven't spoken to my engine builder yet. So I want to hear his views before I make my choice and order the cams.
302's would be huge.. lol Why not some 272's or 280's for the HR?! Thats a topic for another thread. Try to stay on OP's topic.
Edit: You can't read to much into my Sig.. Its from when I had a premium membership! Which offer's you more Sig lines. I'd like to edit it but will need togo Premium again to do it. I do have Nismo intakes NIB in my garage that I also shelfed and never installed.

Yep. Still interesting as ever.
So does anyone concretely believe and dyno proof solid gains from the injen long tube cai's? I was going to purchase within a week or so but I've yet to see (and yes, i've searched) higher #'s of threads suggesting the injen cai's are 'worth' it... 450ish for me in Canada (that's USD) could be invested elsewhere and i'll throw on the stock boxes back?
And for those that have installed the injen CAI's then dynoed right after, are you *feeling* anything?
Also, brady is in toronto and I plan on getting tuned at the same place after the intake issue is resolved... i'll post my results obviously as well, doubt i'll be making 300.. even on that dynapak... however it should be noted that this is not the 'new york' dyno that seems to be getting quite the bad rep, regardless.
And to the best of my knowledge our options are limited in Canada in respect to dynoing facilities, I haven't been able to find a dynojet... period.

I think there is a Dynojet out here in Pickering. Ford Mustang place but I dynoed my charger there. I'll check it out this week and see what it says. Da'Silva racing?
Brian at APH is great with the UpRev on the HR now. Let us know how it goes.

Yeah DaSilva would be the only one I could go to without driving at least 1 1/2 hours, i meant general gta area by that comment my bad, I didn't have the time before to make the venture but considering my recently unemployed status i might as well geniua pig the dynojet vs dynapack... i'll definitely post it however.

Cool, I have an appointment at DaSilva Thursday at 4PM to do some pulls. We'll see what the difference is. I'm very curious... Kind of like a mini version of Mythbusters.

Well the results are in... a Dynojet does read lower, by a whopping 1.07 whp... hahahaha The dyno operator said if the car was running cooler it would have put out 1 extra hp easy.
So I am putting down 301 on a Dynopack and 299.93 on a Dynojet.
What a waste of money but at least it puts to rest the myth that there is a substantial difference between the two.
Next time I read that a Dynojet is different then a Dynopack I'm just going to pop.
THERE IS NO REAL DIFFERENCE! Get over it already.
