AL...hope my flash maps helped you out with your testing in some way! Thanks again for the awesome flash bro!!!

Also - a couple of others had that combo that I have tuned and it worked very well also
On the dyno at the time 264/264 - 264/272 and 273/272 all made within 3 whp of each other - again at the time last spring I was not looking at trq
I will be looking at trq in the future and will update
Hello al-
Great power compare between the 2 cams. I feel even better now about my cam choice of 264's for my ride. However, I located a std dyno flash dyno compare ( 3" turbo bk @ 20 psi dyno @ pruven ). I pasted & plotted the stock cams against the figures above into XL. The compare showed a huge power gain, up to 40 whp in some areas with either of the aftermarket cams? What am I missing? The cam shaft gain seemed enormus?
Is this true? it would be nice to see what hks cams get you in an evo 8 with similar exhaust flash, etc.
Once again, no other flash vendor provides dyno sheets backing up their findings as well as you.
Thanks a lot!

Hey Al....you just sent my ECU back to me the other day. I had my buddy ship it to you. I'm putting my Hallman on tonight. I took the car out for a spin and the car does feel ALOT smoother. I can't wait to see what it feels like after the Hallman is installed.
I only have one problem. My buddy is dropping off a pair a HKS 264's at my house on Monday. I'm guessing I would have to ship my ECU back to you when I have these installed. Do you suggest having some adjustable cam gears as well?

I think the idle problem with 272 cams can be taken care using the AEM EMS I have seen cars run smoothly with 272 cams, the idling problem is not a excuse anymore for not having 272 cams

I have been suggesting the 264 becuase of the vastly smoother idel
BTW - this recomendation has been applicable to stock turbos and stock engines only under 8,000 rpms
I based this opinion on my own reserach testing 8 different cams on my own evo
Today - I have new light to shed on the comparison
Here we have two dyno exmples with power IDENTICAL in the whp area on very similar evos with stock fmic's and the Dyno Flash Fireball 3 - over all two very smooth curves
NOW - we see some difference between the two cams
The 264 makes more trq early at the onset and for the first 100 rpms or so - this is by only a few ft lbs - the whp up top is identical
The 272 cams seem to make the same whp - but don;t some on with the initial boost as hard - loosing 3 ft lbs and at the first 100 rpms of the boost spike
After that the 272's clearly hold the trg curve much better up on top in the power band and don't fall down on trq as fast at the very top as the 264
Through much of the middle the trq is identical between the two after the initial thrust from the 264
Although this is not a perfect labratory like A - B test as I would like - it does shed some more information for those who are making the comparsion as the whp curves on these two cars are virtually identical - BUT the trq curve can bee seem to be holding out better with 272 on top in the high rpms area - even though the horse power is the same
On a drag track the 272 will get the edge when you are mostly in the high rpms range - but IMHO in the street use you will hardly notice any difference
I still prefer the 264 on a street driver due to the better idel and drivability - just my opinion
BTW - I run Jun 264
Just some info to digest
And . . . . if I don;t say so myself - some very impressive and solid numbers for stock fmic cars and the Fireball 3 tecnology Dyno Flash is super, super smooth and even better when behind the wheel

Also in most cases a AEM is not ever going to idle as well as the stock ecu - especially when you get into the winter and cold start situations - trust me I know
Personally on the HKS cams - I prefer the 264 - IF I wanted something more agressive I would try the JUN
Also - Crower has come out with some cams which we are going to try and test
how would you compare the Tomei cams 260/260 11.5mm lift or the new 270/270 11.5mm with Jun or HKS . As well as the piper cams which they offer 265/265 11.5mm and 265/265 11.5mm/10.8mm
