Sign me up.... I would buy at 3k for a drop in product....
Only issue then is tuning
PM replied, lots of tuning options out there! I would personally find someone that tunes with HP Tuners. Their data logging software is pretty awesome and makes it easy for the tuning process.
Did they say what kind of coating is applied? I assume it's a hard, low friction coating, so you might get the added benefit of eliminating both cam and lifter wear.
I was thinking of selling my car….. this may have just changed my mind. I’d be curious to see track results. If dyno tuned I’d be curious to see numbers for fun. Hopefully, you’d allow Barry to post them on his IG. This is interesting. What was your goal with this cam? Was it simply more power and torque? If going to push a higher rpm, would you consider changing the gear ratio? Curious as to how the wet clutch will handle this for driveability.
Haven’t been on here in ages but do you even know the specs of the stock cam to compare to the aftermarket. Stages mean nothing if you don’t know duration, lift, lobe separation angle. Chop comes from positive overlap. If there’s no buck, surge, or idle stable with no changes in tune… hate to break it to you but waste of effort.
Just because the cams have more duration doesn’t mean they will make more power. You need correct valve events or you can bleed off dynamic compression and be left with a slower car.
Send a intake and exhaust cam to Cam Motions. They can read it and now you have a base for specs. Then you need some custom springs. Black series springs probably can’t even handle .500/.500 lift. Lift is your friend. It’s what makes these valve events more aggressive.
engines are pretty simple but amg community makes it complicated lol. The only vendor I’d buy from again is Barry. He puts out a great product and is transparent. The fact that ptg can’t provide specs of both stock and aftermarket cam is hilarious.

The factory cam specs are posted on their website if you search for it, when you purchase their cams they also provide the cam specs. These are a lot more aggressive than factory cams, lift and duration have been added to the cam.
We DID have tuning issues that we had to troubleshoot and figure out through various logs and maps. The ECU kept throwing false misfire codes at idle and kept putting the car into limp mode after certain misfire counts. That has now been solved and Barry knows exactly what to do now for future cam tuning projects.
I'm pretty sure most of the AMG community want plug-and-play cams without having to do any head work or change out valve springs or worry about valve to piston clearance. Also why would companies want to post their specs when they'll just get duplicated by other companies?
Also, nice edit on them sounding just like your factory cams

Actually you’ll read the edit. Ain’t worth arguing with someone who has no before and after ET. Enjoy your cams lol
Would love to see what this does on a Dyno and then compare to a track # s
Probably track times, not much of a fan of dynos unless they're used for tuning purposes.
Need to schedule an appointment with the exhaust shop to re-do my axle back with mufflers delete. Just waiting on my exhaust tips to show up. 4.5" Quad tips.

Michelin Pilotsport cup2 or Pirelli Trofeo are good ones.
Would love to try those out but they're a bit too pricey for street tires that only last ~8k miles on these cars.
Gonna give the RR's a try next, they have more of a slick contact patch for better traction than the R888R's.

Those tips are pretty cool. Where did you get those from?
