FROM JOHANNES PERSSON
=================

Brand new engine for my 1975 super beetle. Built in the fall last year but have not seen the roads or dyno till now. Dyno showed really great numbers earlier today.
Engine spec:
New mag case.
94mm bore
78.8mm stroke
Std length rods
Alu push rods
One of my super scilent split dur street cam.
1.25:1 rocker ratio
Ported and polished std heads with 40x35.5mm ss valves.
Single Oteva90
Ti retainer
10:1 comp ratio
009 distributor with ignitor
48idf Fajs
45mm Python header
Std weight fly wheel
Stage2 Kennedy pressure plate
Daykin disc
Schadeck 26mm pump
1.5 lit deep sump
Check out the wide power band.🏁😎
Mechanical it is dead scilent and perfect in tune, you can see from the lack of stand off from the stacks in comming video.
142.7kw at 6340rpm equals 194.07 corrected Din hp.
248.3Nm/179.43 foot pound of torque at 4980rpm.
Will post video!😊

It could be copied, but I am pretty certain very few people in the rest of the world could duplicate it. JPM has a very different understanding of the heads/cam/compression/wave length tuning relationships than the rest of the VW world.

Even if you got JPM’s cam specs, building something similar to what is listed here with some ordinary 40x35 heads will probably be 40+hp short of his numbers.

I would also love to see the detailed numbers of the heads and cam.

I would rather try and fail than to have never played the game at all!

When I fall or fail I will get back up and try again!

Yeah nice sounding combo. Makes me wonder why so many of the builds here in the states lack power compared the builds like these.

Other than everything being tuned, I see a higher static CR than most go with, which means it probably has a cam with decent duration numbers. The higher cr makes up for power bellow the normal power band. Rpm is still mild. Stock based heads and stock weight flywheel is interesting. Just food for thought.

There is WAY more to it than that. Most people in the VW community only use off the shelf heads, take a guess at a cam, run the compression low, jet it extra fat, and the figure it runs awesome. When really its a 2176cc making 120hp.

Johannes builds very specific heads just for that exact application. He understands how port volumes effect RPM, knows what kind of cross section he needs, and how much CFM is needed to hit a specific goal. These things are all based on math, but above most VW peoples heads.

Once he has the heads figured, he knows how to read the head flow data and can spec a perfect cam just for that application, and its power band.

Rather than using off the shelf manifolds and headers, he figures the wave lengths, and the intake and exhaust lengths are tuned to maximize ram filling and perfect scavenging.

It seems like a lot of math and minor details, but 10 little things that add 4hp each, add up to 40HP more over a normal parts assembler.

JPM is on a different level. He is 20 years ahead of the rest of the VW world.

I am glad you mentioned this because some folks think doing the math on an engine is pointless.

I have spoken to johannes once and i think he is the best in our hobby.

I believe that small valves can make big power they are also easier to control. The cam on this engine i think is a split duration cam.

Yes this is the holy grail. I am going to talk to johannes again. I am curious as hell about this setup.

194 WHP and 179 ft/lbs of torque from 40 x 35.5 heads. Some guys struggle to make this even with 44 x 37.5 valves and if they make it the engine breaks a lot.

With the current state of aftermarket 009 distributors, I wonder why it was picked over some of the more modern options. Think

So does that mean it made 194hp at the wheels. Very impressive !

I thought this was flywheel horsepower, not WHP, just based on the description at the top of this thread. Is the 194hp ,in fact, at the wheels?

He is probably also 20 times on the price point.......I'm sure you can't get a set of his heads for 500-1000 bucks.......95 plus percent of VW peeps are too cheap to spend that.

I have spent a 1000 plus on my panchitos. I am thinking if i should change my heads Johannes is definitely getting a call. I want to buy his king cover valve covers since i hate the bolton covers that i see online.

I doubt $1000.00 is even going to come close to that set of heads he built for that engine........My guess would be more like $3000.00 plus not including shipping.....now add valve covers to it...... Shocked

I've seen a set of Panchito's that weren't very impressive out of the box. In fact....I think they are sitting on the buyers shelf due to issues even though brand new.
Almost like my new set of DRD's that were a major disappointment........

I'd prefer to spend money fairly locally so I would probably get a set of SL-1 heads........but for now adding some boost is cheaper.
