I went with MHP cams witch have slightly higher lift then PTE cams, I'm taking it down to be tuned in a few weeks so I'm not sure how the gains will be compared to stock. Once I get it dynoed I'll post up the sheet and hopefully the cams are worth it
Unfortunately I'm doing so many other things I won't be able to tell what difference the cams made.

Yes, I sure dont want to bend any valves.

I hope so too! I actually talked to Patrick before I purchased the cams and he's the one that turned me onto them and gave the information in the first place, so imagine I'm going to be safe. Thanks for looking out.

Oh, and people can say what they want about the idle it's really personal preference but I'm hoping for a lope to the idle Even with a lope this will be my well behaved vehicle!

My bad, I read that you lost a 10th. I assume the power scale would increase with larger pulley (AKA 200mm and ported heads) with the cams.
Still don`t understand why most these cams have idle and lope issues, they are just to small. Must be LSA or how they are degreed. I started to have my heads ground out to allow me to have custom larger cams made to my specs but then passed due to time.
Ok , found the thread with cam specs. https://mbworld.org/forums/3004898-post33.html
Really hard to tell why the SLR cam makes more power but it is the little things that must work. Tighter LSA, diffferent advance and maybe more Exh. help for high end flow.

I agree, he may have been involved with the cams but I won't presume to speak for him and yes he is the one to go to for that type of information! As for the drivability issues, I think correct tuning plays such a big part in low RPM day to day driving and it normally gets largely ignored and then people assume it's the parts fault. Just like any other major modification to an engine you have to correctly tune for drivability.

The purpose of this thread, was to stimulate new ideas for cams and go over any issues with current cams. I also was hoping for hard facts on any gains, averages and track times.
Have to thank Chiromikey for all his info on the SLR cams.

Maybe Betreza can chime in on this but perhaps faulty installation of the PTE cams could be the cause of the lurching and stalling issues. I believe he posted these symptoms with his CLK55 S8+ until he had Kleemann reinstall his PTE cams after they discovered that it was off by only 1 tooth. If that is the case, then I can probably live with a little more of a lopey idle in exchange for another 10rwhp over my Kleemann Cams.

Pat with PTE called me today (stand up guy) to verify what you mentioned about a faulty install. He also had 1-2 cars that complained that had 82mm Tb`s leaking around the adaptor plate or warped from being welded. I know I get surging with stock cams, when my TB leaks a little. He mentioned he only had 4 sets out of the whole batch he invested in a few years back.
For now, I am going to test and run what I have, then look at cams again later.
I think the SLR cam may be the only true desinged blower cam going but just not aggresive enough for what I would like. The other cams seem to be made for all the 5.5 engines and few other naturally aspirated motors. At this level, I would like "job specific" duty cams.

If the same cams can go any many motors and are marketed for them too, then which motor are they specifically desinged for? I am just asking and gathering facts to find the best cam possible (if not maybe someone will make one)? I would want 30 RWHP to change and pay for a cam. That is a fair dream. IMO
55 blower motor is a very small market, so are the cams made specific for a 55 blower car or for a certian motor that CAN work in many applications? You pick up power, then they work to an extent but are the optimized for a Supercharged boosted 5.5 motor?
One fact though: Marketing and Design are two different entities. .

LOl, yes that is the motto but running out of time for the mile and only have put ported heads on so far. I think my to do list was 14 items long. Check one and it is September 16th already.
Sorry to hear you had or have a bad experience with your cams. To give some credit to the cam itself, it is "usually" not the cams fault. Cams dont surge on their own but they can bring out an existing problem with tighter LSA. Vacuum is usually the culprit and that is caused by leaky throttle body`s, older vacuum lines or other leaks. Of course , skipping a tooth on a sproket could be horrible. Tuning is also key to get smooth part throttle, idle and WOT! They do change the fuel curves, so they need to be tuned for each driving condition.
If a lot of us shared data log info, a lot of problems could be solved online. For example watching your LTFT. More than 5% delta from left to right side can denote a air leak or air leaking at header. This throws 02 readings off and new problems show up. Checkign boost, idle and TPS are all nice to know. Low TPS can cause surging , idle isues, codes and be a big pain in the $$s.
930chas Cams were the worst experience I had with my car and I know quite a few others that shared the same woes. Take that for what it is worth.

I am only saying when shopping cams for these cars, do your research.

Again I've been running PTE Cams for past 7K Miles... hard driving, revs, normal driving, highway driving. Not a single issue besides the car sounds absolutely bad *** once it's warmed up and idling with the super sprint long tube headers. I never did an immediate before dyno install and/or an after... My seat impressions tell me the thing screams in the upper RPMS.

Thanks man, but fortunately I know all this stuff. Monitored my car closer then most. This was 100% strictly a cam issue. And these same "brand" cams affected numerous other cars in the same manner, also owned by individuals in the know.

Heads will out produce cams at Peak HP and TQ and most of all average HP and TQ across the band. You may want to look into that route as an option, since cams are not working for you.
