The Kleemann have visibily different lobes to OEM. Lobes have straighter ramps and fatter. Whatever that does I dunno - I dont think overall lift is much higher if at all. I measured them up with a micrometer but I dunno what I did with the data. I am sure its on the forum somewhere on the big cam comparison thread.
Kleemann say 10-20 hp depending on the base setup you have ... the more you are flowing the more the cams help....
Its true you cannot go agressive here and the PTE solution has it maxed out... flowing the heads is also worth a fair bit of power according to Kleemann.
For me Kleemann cams and ported heads are about the most you can do ... not taking away from the PTE arrangement but it does seem they need custom tuning to get the best out of them.
I am waiting on some Cam dyno charts from Kleemann and Ill post it up.
Ah also - they said the cams add power throughout the curve - at no point is power lower. Again a few mods have made me as happy as the cams - I would say almost on par with the pulley upgrade...

A note on cam lobes, Since there is limited room to increase lift on the cam what is left is changing the shape of the lobe, by making it more vertical(called the ramp) the can open the valve faster and then they can flatten out the top of the lobe making it longer(this is duration) so the basic effect is a valve that opens fast and stays open longer allowing the the cylinder to fill longer and exspell better. In the end your engine is nothing more than a air pump, the more air in and the more out the more HP it will make.
The OEM lobe ramps are almost concave, the kleemans are straight line from base to peak from what i remember.
I remember reading somewhere (a very long time ago) is that all else being equall all a cam can do is move the torque curve up and down the rev range and cannot develop more torque. Perhaps F/I is different...
Sorry dont want to go OT here but I find this stuff interesting as heck!

There's one item that I'm on the fence about....titanium retainer rings. Most say to do it just because my tech will be right there, I need more then that to proceed. It's only a few hundred bucks but I need to fully understand the purpose of anything before it gets installed on my car. If any of you guys could fill me in on the pros/cons vs stock retainers it would be appreciated.
Just to note - I understand that they will allow for higher RPM's without valve float, but how and why? Thanks again guys and I honestly believe 10.4-10.5's will be here at traps near a 135 mph will soon be here.
I may also install a torque converter to help get me into the cams powerband a little quicker. Could anyone suggest a well known shop that makes them for our cars other than Eurocharge.

Hey Alan, Titanium retainers are a great way to reduce weight from the valve train. They are strong. Good insurance for the motor. They will not hurt you that's for sure, especially if you plan to raise your rev limiter. You should be thinking about stiffer valve springs as well. The titanium retainers should go hand in hand with the springs.
High stall tq converter should help too. Cant wait to see what you will run. BTW did you properly cool the motor pre dyno run like you may do at the track? Or was it heat soaked pulls? Just curious if you decide to cool down iats before scrapping that idea of increasing boost.
Have you considered a good methanol kit? I certainly would if I was running your mods.
Go get em buddy!

Stock is 18.61 Grams & Titanium is 10.22 Grams. VRP / Victor posted some pictures at one time , & I might have too. I do stock this these. Cheers _PTEngineering

Since I'm tearing down my motor to fix an exhaust valve/compression issue and install titanium rods, I will check my valve clearance with the VRP/PTE cams and see if I have room for more lift. If so then I'll look into getting longer rocker arms made out of titanium. That should lighten up the valve train further and free up a few more horses on the top end. I'll keep you all posted..

Currently my project is at a stand still again. Vadim got my 5.7L running, but that’s it. No headers and exhaust, crank pulley, HE cooling, 82mm Throttle body, and he never connected the top mounted coolers. What’s worse is when I was driving it last it dropped an exhaust valve and lost compression. So it’s time to move on. At least I have the ability to look back and laugh.
When I return stateside I’ll bring it to Evosport to have them complete the build. No worries brother, I’m still excited about my project and on track to build the strongest 55K ever!

Yeah, it has been forever! I dropped off my car there Jan ’08. Hey, I told Vadim to take his time, which he has. I can’t fault him for that!

I was really thinking (and hoping) that your project would be the one that Vadim completes/concludes this year, as it sounded so promising and so close. Why did you guys stop? It seems like the hard part (the engine) is done. The headers, throttle-bodies, HE, etc.... is the easy part

Evosport will not only complete it but get it done in a timely professional manner. Stay tuned!

Cams are in and all he needs to do is finish up a few things which inlcude mounting the SC and she should be fired up this evening. Damn...I'm getting really excited about this. I'll post back one I hear something.
Yo Max, what up brotha! It's been a long while bro, give me a shout when you have some free time.

My tech is bad a$$$$, the car is up and running with no adjustment needed to the idle. I haven't heard it yet but he said it has a slightly rougher idle but nothing significant. He also mentioned that the idle could be adjusted but at this point it would only be a matter of personal preference. To tell the truth a slight lope idle sound pretty dams sexy.
I have a few more things to get done due to the fact that I lagged on ordering parts
. Man oh man this is getting fricken exciting. As I promised I'll have a full write up with dyno sheets, track ET's, traps, and drive-ability. These cams will be custom tuned along with my other new mod..... In 10 more days and we'll have all the info needed, tune day on Thursday and track day on Friday.
Stay tuned..................

Looking forward to your feedback on the cams. I'm sure you will be pleased once they're dialed in.
If you dont mind the rougher idle or your tech can smooth it you'll be in great shape. You'll feel the difference the second you get on the throttle, thats how aggressive these cams are.
Your input helps the community Alan, thanks for sharing.

Alan, Your car will be unique with these new Mods. I see a 10.50 or better in her, if you hook. Eagerly awaiting driving impressions and butt seat dyno.
