Raptor Cam and lifters

[Lids]

I currently have a web cam 86c and using the TP lifters.

but....

I now have a choice to either retain the webcam but use the hard weld version.

Or run with the JPM raptor cam.

Opinions?  does he just ship the cam?  the JPM lifters are heavier than my TP's and they will work fine.

[H67bug]

Maybe contact JPM...he is very helpful.

Was advised that ceramic lifters are recommended but he felt his the next best option.

[Torben Alstrup]

Why change the cam Has it gone flat for ya ?

For street/ strip use the 86c is a very hard cam to beat wrt driveability, even for Johannes. Race is something else.
So unles something is wrong with it I would stay with it and what you already have.

cam is not flat, in fact not used yet.  But  i am looking at building this new engine with longevity in mind.  Hence why using TP lifters and mating it to a suitable cam, so no chance of flat spots or breaking up.

[Tobi/DFL]

Hi Lids,

Johannes won´t ship the cam only but you can use a raptor cam with your TP lifters because the lifter radius is compatible. That´s what Johannes confirmed when we asked him.

Cheers,

Tobi

Thanks Tobi, I will get my engine builder to try and contact him.  He made a custom grind for his car, so hoping that might have some influence.

I have installed a Raptor cam in my car and I would recommend the whole set up aluminium pushrods, JPM lifters, Oteva springs and JPM aluminium retainers.

I must say its incredibly smooth and quiet race or street you can't go wrong!!!

Paul, you have no concerns over bent pushrods?  I have a set of mantons I was going to use.

Paul, you have no concerns over bent pushrods?  I have a set of mantons I was going to use.

No none at all so far I have reved to 7,500 with no problems, but I'm using JPM pushrods which are a special grade aluminium.

The Mantons are so heavy also the aluminium pushrods expand better and are therefore leave less valve lash. This all helps maintain your overall lift and keep the whole train soooooooooo much smoother!

If you go for it you will not be disappointed.

All the best Paul

I use Mantons and they are indeed extremely heavy compared to the JPM ones...

Do you use Titanium valves and run single springs also? Or SS valves and double springs? What´s your spring pressure?

I use titainium valves and dual Oteva springs installed at 120lbs seat pressure.

Rather than start a similar thread, I thought I would tag onto this one.  I've been using the Web 86C and it's been okay, but I also feel the need to step up a notch to more of a race cam, perhaps something similar to FK89, but in the Raptor line up.  I tried the Web 226 which was not a good cam at all, and the Web 251, but it appears to have been ground incorrectly (I think their quality control has perhaps gone downhill).

Any feedback on the following Raptor cams and your 1/4-mile results in a heavy Beetle?  My engine is a 2332 cc, IDA's, 1.75" exhaust, JPM MS230 heads.  Since I have the JPM heads, I might as well match them to a Raptor cam:

JPM00206:  280 degrees, 10.5 mm lift
JPM00406:  282 degrees, 10.7 mm lift

Thanks!

its not just the cam, they come with followers, and i would also see if i could afford the matching pushrods!  this lot will set you back £1k

[Torben Alstrup]

I have come across an unprecise ground Web cam once before. It happens. But they swopped it for me, no problems. I have seen lots of Engle´s that are out by as much as 4 degrees. But for some reason we never hear about those (?)

If you want to be able to drive it on the street, I would choose the milder one of the Raptors - Remember, your CR must come up too.

[Paul Bate]

I'd just send an email or call Johannes about the cam choice he'd recomend.

My cam has more duration & lift than the old FK89, however it's so much smoother you would never know until you hit the loud peddle 

Heyden Mizon has one installed in his street bug perhaps he can put up some feedback as he's on the CLF!

All the best Paul

What are TP lifters? 
I can usually figure out what you're discussing but this one has eluded me
It obviously is because Eurospeak is not my native tongue...

Thanx in advance

[Frallan]

Tomas or is it Torsten Pieder or something like that, lifters.
German lifters.

Thanks for the feedback, Paul...I appreciate the first-hand feedback.

I will definitely contact Johannes (I bought the MS230 heads from him), but I also wanted to hear some experiences from other racers as well

[Lids]

neil i have ordered one (well JC @ stateside has done it for me) I was going to run a webcam 86C but have gone this route instead.  So have asked for something similar.

I  have the MS230 heads on my engine and also use his cam. very very pleased. Just opened the engine after the season and everything look perfect Cam wise.

 Thorsten only made 26mm so I had him make the 28mm ones for me a couple of years ago. It took some time to get them done but they are the best. They are also only 56grams. I am the importer for them here in the US. I have them in a few superstock cars, turbo cars and street cars. No issues at all. They have been pulled out and re-used with many different cam grinds. They are not cheap but well worth the investment.

[Shag55]

Here is a few pics.

[Fasterbrit]

Raptor cams may well be expensive, but they are worth every penny in my book. I gained 70 hp with just the cam change (much better harmonics eliminating previous valve float). Having stripped the motor after 3 race meets to inspect parts, the cam and JPM lifters are in perfect shape. Absolutely mint, and for the first time ever, my valve springs all still have their full pressures. With my previous Scat cam the valve springs used to get so hammered, they would lose approximately a third to a half of their poundage - especially the exhaust valve springs.

You won't regret buying JPM 

[bedjo78]

JPM lalso offer roller cam?

[Tomi]

JPM lalso offer roller cam?

Yes, I have JPM roller cam in my engine. I had my own cam blank which he grinded.

[Udo]

Who needs a roller cam ? May be if you want to break any records

does he have a website?
