Old Man Cam - dyno results We were finally able to install the "Old Man Cam" in a customer's car yesterday.
The reasoning behind this cam was to retain the stock idle sound and quality, but still make respectable power and not sacrafice any driveability.
The customer's car had the following mods:
2000 Trans Am, 6-speed
-Whisper lid
-ported MAF
-TR ported TB
-Hooker longtube headers w/ off-road pipe
-cutout
-LS6 intake
-stock rear w/ 3.42s
-ASP pulley
The only changes were the addition of the old man cam (Comp 918s, Ti. retainers, TR 7.400" pushrods) and an ASP crank pulley:
Old Man Cam dyno results
Specs on the old man cam: 214/220 .602/.527 115* (2 degrees retard ground in)
We were a little concerned with using the Comp 918s, but they worked extremely well. We were hoping the new Comp dual springs that fit in the factory spring pockets would have been released, but they are still in testing.
Overall, we are pleased with the results! The cam is still using stock tuning and stock TB hole and doesn't even try to stall. If you don't listen close enough, you would never even hear the cam, even with the cutout open. Through the catback, it is totally undetectable.
We will have a more of these cams in stock early next week if anyone is interested.

Re: Old Man Cam - dyno results My TR227/224 idles/drives like an old man cam. I don't get how it could be ANY more drivable or tame than this cam. Nobody can even tell its cammed! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Re: Old Man Cam - dyno results Looks great- the powerban is almost identical to the stock cam. That is some nasty-high lift though <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> .

Re: Old Man Cam - dyno results Nice gain throughout the entire rpm band. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> That should have excellent drivability. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
Just because 918s are holding now doesn't give me confidence that they will hold 8,000 or 12,000 miles from now. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> How is the valve train noise?
Any thought about a midsize cam based upon that design, maybe a 220 intake with a 600 lift and TR's 224 exhaust lobe with a 114 LSA?

Re: Old Man Cam - dyno results I'm highly considering the '02 LS6 cam and held myself back this week from ordering it. I want to retain stock idle at all costs and no initial tuning. The bad thing about the LS6 cam is that it provides no low end gains and doesn't make power til close to 4000rpm. What could you expect your cam to do throughout the band on an '00 with stock manifolds and maybe an off-road y-pipe upgrade?

6600 rpm clutch dump of death Administrator
Re: Old Man Cam - dyno results What sort of heads were used in this test. My reason for asking is that my stock 2002 Z06 puts out 372 corrected by simply removing the airfilter lid. It has the stock LS6 heads, stock exhaust, and is in a C5 which should have a bit more driveline loss. It was my understanding that this cam was closer to 400RWHP. Is it my understanding that in looking at the test results 375 was obtained with stock LS1 heads? If so, that seems a bit more impressive.
Anyhow, just curious. Thanks for the info.

Re: Old Man Cam - dyno results We have had very little experience with the 02 LS6 cam. This is going to change in the near future though, as we are planning to swap it in a f-body very soon.
These were LS1 heads.

Re: Old Man Cam - dyno results The valvetrain noise was no worse than stock. It was kinda weird doing a cam swap and getting no lope or extra valvetrain noise. lol
I feel the 918s will work fine. Regardless, you should replace the springs once a year with almost any aftermarket cam. The cam is definitely going to be hard on the springs, but the 918s are up to the task.

I don't intend to even look at replacing springs until I get around 30-40K on my 26918s, this will take me about 10 years to hit LOL! I have a B1 cam and the car does not really see much drag strip action.

Re: Old Man Cam - dyno results Regular price on any TR cam is $429.99. However, all valvetrain parts are 10% off this month (until Feb 28). $386.99 would be the price after the discount.

Re: Old Man Cam - dyno results im quite interested in this cam, but i know almost nothing about camstuff
since these worked good with stock LS1 heads.......would it show much improvement with a good set of heads?
