Which one and why? Anyone with dyno info on the cams? Average HP across the band go up or just peak? Idle or tunning issues? Codes? 1/4 mile times increase or decrease?

There is a member on here selling cams UR NEXT I believe is his nick on here. He has new cams for sale if they are not sold yet.

I read all about the PTE cams and I hear from alot of folks here that it's just TOO lumpy and uncomfortable for daily driving. As for power difference, I would also like to see the difference before and after on the same car on the same day or at least same dyno with same weather conditions.

This still might be last mod since I have Kleemann cams in my car. Only Betreza has said it was not too lumpy. Allmost all the OEM 55k guys either complain about the idling or trying to sell them.

+1 PTE, been running them for awhile

Thanks, I saw those.

I hear you bro! Lets work together and find info!



Great to hear! You have any codes, idle issues or other info to show power gains? Have you ran at the track yet? Just looking for as many details as possible, and it is cool if you don`t have the info , just asking.


I was hoping PTE would just send me a set to go with my heads, track times, mile times and dyno testing.

Exotic-Metal cams...Boom

I have a set of Kleemans that Im going to throw in as soon as my car arrives from shipping. SHould be here in a week or so. Ill post my opinions asap.

chiromikey is selling his SLR cams!

Hey

I got kleemann good high rpm power

I spoke to a very reliable source about the three cams mentioned here and are as follows from least aggressive to most aggressive: slr ; kleeman; pte. In terms of power the slr and kleemans are very close with 15-20rwhp in the upper range can be expected. Noticeable increase in lope in kleeman and pte.

PTE.

i've "heard" the pte's make the most power but never seen any actual proof...which is weird considering how many people have tried them. unfortunately, they also seem to have a lot of drivability issues. i also remember seeing back in the day that the kleemann's made similar hp to the slr's but changed idle characteristics a bit. i posted some dyno and track info on the slr's years ago so it's around here somewhere but most people were averaging 15-20hp above 3k rpms and i dropped a tenth in the 1/4mile. the slr's have zero idle or drivability issues but needed a tiny bit of prep to fit properly.

I would pm betreza, he's located in Katy. He's running pte cams in his Kleeman clk55.

chiromikey

it might be hard to draw a fair conclusion comparing the behavior between two different motors...

loudandheard

The motor is an m113, it's essentially the same engine with higher compression. I think the major difference is the supercharger and maybe the pistons, other than that, it's the same engine. His car has a kleeman supercharger, so it should be fairly similar.

chiromikey

i do agree that it's the same basic block assembly but there are enough differences just to accomodate the s/c and compression you cited that one has to conclude they're not the same motor ...ie the heads, valves, pistons, maf vs map...well you get the idea. i think it's less of a stretch to say the e55 has the same motor as the slr and we know that's simply not the case.

loudandheard

Good point.

badm

I've got Kleemann's and all I can say is the power and pull in med-range and top end is unreal. I've spinned the tires and fish tailed and 60mph plus ,.. big torgue ... Badm

Woah, really, hmm

Exotic-metal55

Thanks for the cam honesty. Been while but it seemed the SLR cam specs compared to our stock cam specs, did not show to be larger on the intake side. I recall, it seemed to have less intake duration than ours and favored the exhaust event more. That would back up the engine having better heads, more boost and other intake goodies. Maybe on degree less lobe seperation.

The specs are posted on this forum somewhere.


Hey Jake, why do you want me to run SLR`s and go slower-maybe?

chiromikey

it has been a while and you're right, the only differences i can recall were with duration...and i agree with your additional conclusions/assumptions. but do you not recognize that you've addressed all these differences? either way, even with only a 178mm pulley, 78mm tb, ff headers, and k&n filters i still gained a tenth in the 1/4mile and showed gains on the dyno.

btw, i'm not trying to push mine on you at all as i think i've decided to put these in my new motor. just want to assure you that slr cams will not make you run slower!

loungn14

possible lol

na its just from what I have been seeing, there are a ton of people having issues with them (cams) and seem like more of a hassle then what its worth..

Exotic-metal55

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.

chiromikey

nice find...i haven't seen that in a while! when making some general measurements after finally getting my hands on a set of slr's back then, i remember being pretty disappointed that the cams were not significantly different but after the cash outlay i went ahead with the install. before i got them i was thinking old chevy days and expecting 50hp. after getting them i was praying i didn't have two new paper weights! so seeing the results on the dyno and the track were very pleasing and even more so after seeing all the drivability issues other cams later had.

PACougar

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.
