David,
Could you give us a description of the WORKS cams? I know some of the other cams (like HKS) produce more power, but reduce day-to-day driveability.
Where would you slot yours at??

thanks.

 

As the name implies, the WORKS Power Cams slot between an HKS 264 and HKS 272 cam. Basically, we were addressing the issue of how to maintain the drivability of a 264 series cam while providing more of the raw power gains provided by a 272 cam.

Since we had the luxury of designing a new cam for the Evo from the ground up, we didn't have to resort to ham-fisted attempts at running staggered cams (i.e. 264 on the intake side, with 272 on the exhaust), but instead, were able to find a cam profile that allowed the Evo to maintain nearly stock idle characteristics, but still move more air through the cylinder head than a 264 cam could ever hope to provide. In addition, the WORKS cams allow one to maintain the stock valve springs, retainers and cam gears for a cost-effective, drop-in cam upgrade and a stock looking engine bay.

Thanks for the concise explanation!

The website says $699 a set. You need 2 sets then?

 

Evos have a "set" of cams. Also a staggard approach is not "hamfisted" - What is the lift of your cams? The durations between 269s and the "hamfisted approach" are exactly the same

 

Nope, a set refers to a pair, and that is all you need -- one pair (intake and exhaust).

david,

my ecu is stock, do i need to run P2 to run your works 269 cams??? will i pass smog test/emission test with these cams???


ps-waiting for works turbo

 

Curious about the lift as compare to the HKS and JUN. Are they American made?

 

MP5 what do you think about: https://www.evolutionm.net/forums/sh...ight=retainers

Seems the OE springs and retainers are pretty weak. I think this is something that really needs to be looked at when using the Works cams with their high lift profile...

 

The cams require a remap of the ECU -- whether or not you already have the P2.

As far as emissions testing goes, they are being subimitted for CARB testing and certification. Unless and until that is granted, they are not being sold as emissions compliant.

No need to run upgraded valve springs or retainers with this particular cam combo. I am not in a position to address David Buschur's findings regarding the relative strength (or lack thereofe) of the stock valve springs, but can only comment -- as I did with the allegations that the stock Evo fuel pump is weak/defective -- that our cams allow the Evo to work well within the envelope of factory tolerances at the 7,800 rpm rev limit used in the Brain Flash. At higher rpms (those exceeding 8,000) we would recommend the WORKS titanium retainers and uprated valve springs.

Yes interesting stuff for sure. I will be trying to get to the bottom of it but as you say DB has spoken and I do highly respect him. The works springs and Ti retainers dont seen like bad insurance for $300. I just find it hard to believe the parts bin has degraded so bad since the 1G that we might actually be looking at overstresses with fully stock components

 

i believe that anythin pass the stock settings on rev limiter will required an upgrade of the valvetrain .
evn if you are running more duration and lift on cams

 

Your not making too much sense here goku

 

I always believe when upgrading cams it's best to upgrade the valve springs. Stockers weren't made to handle the stress of higher lifts. For a prolonged period, the springs will soften and get sloppy lifts.

As for retainers, I never heard anyone breaking one for the past 10 years. Is it possible? Yes.

 

Doing what you do outside of the automotive world David, you know how much sting "allegations" can have when found to be true... Just hurts so much more when someone already brought the issue to your attention and you have ignored it... as in law, it's not the thousand times you got away with it, but the one time you didn't that leaves your *** sore...
