O.k. i live in the tropics and would love to know if these cams coupled with say a steve tims stage two will work with 90 octane gas ( 10% ethanol added ). Also is there any special requirements for combustion area reshaping.
Would love to use one of these with a 1914cc or 2276cc engine.

Johannes has a cam for most any application.
You would be best served by contacting him to get the perfect match for your combination.
Sorry I can't help more ...

I have a Raptor cam in my race engine. I run E85. No problem. I have to ask though, what does the fuel have to do with the cam?

Well i was look at the fact that you choose a cam based on the compression you can run for the fuel you are going to use. They say for a daily driven t1 engine you want a dynamic compression ratio of 8 : 1, also your opening and closing of your valves relative to BDC will have an effect on your compression.
My engine will be street driven. What was the cost of your raptor cam.

EVERYTHING has to do with cam selection. Weight, gear ratios, frontal area,tires, terrain, compression ratio, octane and driving habits/ environment, to mention a few. If you have a well versed cam person that knows the effects ,takes them all, or at least the most pertinent elements into consideration and can make any CNC profile, you are pretty well assured that you have the best cam that can be expected.The continual research, experimentation and power improvements of the camshaft/valve train gurus of just the last 20 years. are truly amazing...Yes after over one hundred years, they are still learning new things about the lowly simple chunk of iron. Computer simulations, Spintrons and gas or flow dynamics are but a few of the tools in the arsenal of the really good engine builders/designers of today. If you are looking for that perfect cam with the most desirable qualities you certainly should take into account the differences inherent in an blend versus an all perto based fuel. Which by the way is far from straight gasoline.Just because two fuels are each labled 92,100 or 115 octane does not mean it is the same stuff... or will produce the same results. . Power increases of a few percent, drivability, and economy are all interelated. There IS difference, and it WILL make a difference. To not consider such is leaving something on the table.. Of course, it all takes cost time and money...And talent. Or you could just toss in that 40, 50 year old mopar profile and call it good.

I recently purchased some MS230 cylinder heads and received a flyer with some information about the Raptor cams: lift, etc. I know Johannes is a very busy man, so this might help you in the meantime:

Apologies...wrong flyer. Here's the one with the Raptor cam info. Heads were 18000 SEK (export price) plus shipping.

Lifters and cam, but yes this seems expensive, but not when a decent set of tool steel lifters are $450

Also, the Raptor kit price listed is the local Swedish price. The export price is 75% of that amount, as you do not pay the local tax, so that should knock it down to 3746 SEK which would be $615 USD plus shipping. As stated, the kit includes the matching lifters and camshaft...the lifter radius is matched to the cam lobes as well.

I picked up over 60 horsepower at exactly the same boost with my custom designed Raptor cam. It also allowed me to then add more and more boost until we called it a day on the dyno. We ended up with 638 horsepower (560 rwhp) after a day's mapping.
Now some of you may doubt that a simple cam change will not have the drastic effect that we found above, but prior to the cam change we could not get any more than 414 hp. JPM's approach to cam design radically changed the harmonics on my valve springs and eleminated valve float; which was the issue holding the motor back. We hadn't realised the valve float until it was too late and a lifter broke. After rebuilding the motor with a Raptor, everything changed for the positive. The car previously ran a best of 10.37 in the quarter and now runs a pb of 9.56 @ 146.25.
Other than cam change and adding boost the motor is exactly the same as before. No other mods were done.
For me the proof in the pudding is always in the tasting. I have no doubt that Johannes is turningthe VW camshaft design on its head. He is possibly the most gifted engine designer and builder out there in VW land.
Initially I was shocked on the price, too. But then I weighed up the cost of another rebuild and figured with the new cam I was on to a winner in the long run.

Boy i would love to build my 2,1 MV engine into a turbo engine. I have KS pistons and was wondering if these can take over 300HP.

Got the nod yesterday that my new crank (Secret) has arrived and is currently undergoing balancing. Then it will be time to mate it up to the raptor cam that arrived in November (another secret grind). Lets see what it does.

Do raptor cams come whit true tool steel lifters?
so you can reuse them over and over again even if you change camshafts?
if that the case the prize is not bad!

yes, but they are heavy compared to TP lifters.

I´m no expert but I think the main idea is that the lifters supplied match the profile of the cam.

Are you sure that the JPM lifters are tool steel? Break-in instructions say 30 minutes at 2500 rpm with 80-100 lb spring pressure, so that sounds more like traditional lifters...

They are ordinary, matched lifters to the cam. Super hard lifters is like putting a patch on a broken neck. It might work but the neck is still broken.
What is the correct price for a cam with lifters you KNOW will not have a problem and is custom made to suit our engines?

Upon inspection, I really don't think they are 'tool steel' from JPM.
They look cast to me ... ?

Sorry , but all other cams need a hard lifter . Like the ceramics or the old wizemann , so they work for many years

I do not know about the hardness of the cams. It looks like it is better to get both from Johannes. I think it is a good idea to sell both matched
