You’re correct in all you’ve said about Wayne Schofield here in the UK.
This is his dyno curve from my Mk 1 996 GT3 fitted with a factory Motorsport Department 2009 3.6
Cup engine with some trick inconel headers, lightweight big bore silencers and decat. Wayne engineered
the strategy for the two resonance flaps from scratch, and designed and installed the driver’s and operating
systems for them. Having done so he then mapped the whole lot.
His dyno curve shows 465.7 flywheel BHP and 404.8 wheel BHP.
Apologies for the poor quality of the image, it was screen grab taken by Wayne.
It's not a print out (as I posted) AND BHP is clearly labeled as BHP - which it is not in the graph I posted.
If the graph can be confirmed to be BHP, I will take it down.
That 4.1 mapped by Wayne will be Hartech’s development car. I believe it’s a 996.2 Cabriolet or Targa, but don’t quote me on the last bit. It may be running some Top Gear headers, but that’s probably it. In addition to the 370BHP it also has a nice big slab of torque, so would make a cracking road car. I was set to drive it last December, but decided to wait until the weather is better in the Spring.
I’d say there’s between 15-25BHP to come out of it with some further fairly straightforward mods.
There’s also a Hartech 3.9 conversion in a 996.2 in the UK, it’s fitted with some cheap aftermarket (Top Gear) headers and a 997 airbox and it made 366 BHP and 324 torques on Wayne’s dyno.

You can believe or disbelieve what you want, I’ve been transparent the curve I’ve shown was for a Mezger, and unlike you, I’ve no axe to grind or indeed skin in the game.
You clearly stated Wayne’s dyno and it’s readout/printouts don’t show BHP. My screenshot of the curve (taken by Wayne) shows it does. End of.
If you feel so strongly about the lack of BHP in the dyno chart, give Wayne a call or drop him an email, but don’t expect a quick response, as he’s far too busy to drop everything to settle petty arguments on Internet forums.
And this is the dyno sheet for the 3.9 conversion I mentioned. To the best of my knowledge only Wayne does Hartech’s mapping, but this may be Hartech’s own dyno sheet :
I have to say it never ceases to amaze me that the likes of Charles and Jake spend numerous hours posting on RL, only to be frequently met with outright hostility from some of the more verbose contributors on here. I’ve no doubt Jake won’t miss it one bit.

Are we not speaking the same English - I know some things changed over here after we kicked George out but I think for the most part, we should be able to understand each other through written communication.

Everything you are posting calls BHP out as BHP - the graph I posted does not say BHP, anywhere.
You may very well be right, but I am trying to confirm that before I take it down.
I'm happy I could provide some amazement to your day.
What are you doing in this thread if you’re not doing that ? I value your opinion of engines and data that aren’t yours, none at all until you put your money where your mouth is and provide something of value.
All you do is talk.
ETA. I had always thought that Charles was a pretty smart guy… that was until he gave you the keys to represent his company here. He brought facts and although I disagreed with him on efficacy occasionally, at least he wasn’t a straight up junior sales guy.
I shared my prior experience with two dynos that offered data gathered at the wheels/ hubs and offered the ability to plot this as flywheel/ crank data. This loosely supported what Porschetech3 was stating.
Nothing more.
I e seen a lot of things across various industries in the automotive world. I’ve never seen someone so interested in Porsche engine performance, but the same person isn’t even concerned with retaining a Porsche engine, in their own Porsche.
Why care about the performance of these engines?
BTW- I’m not in sales at all, but I do have a Porsche engine in my VW.

Because I want these cars to kick *** on the road and the track for a long time to come. I'm interested in engine performance - In a Porsche.
I've never seen a vendor so interested in talking about engine performance that refuses to post dyno graphs for the engines they produce.

Jake was always adamant about why he didn’t post the graphs. He pointed at a German phrase on his wall in the engine room and said “figure that out”. It took me a while but I learned that the phrase said “the enemy is always listening”. It was used in German radio vehicles in WW2.
When I told him a few days that I understood it he then explained that if the graphs are posted there’s nothing to stop the other guy from just lying and making his numbers bigger. That may not make people happy, but I learned quickly that he didn’t care about that.
Here’s one from last week. Ran out of injector, this run was with max duty cycle.
This is a customer’s engine and one like it can be purchased.
You can figure out what size it is, and guess at what it costs. Yes, it is an M9X and started life as a 3.6.
I performed this test myself. These are wheel HO figures from the FSI Dynojet model 248.
We only did 3 runs and stopped because it was too lean. Turned up the fuel pressure and still it was too lean. The plots are bumpy because of the lean condition.
I’m sure you won’t be happy, but at least you got a graph.

Geez you guys need to upgrade systems over there my gosh.. do you even have HD television at this point
I suspect Wayne’s too busy living in the real world/earning a living by maximising BHP figures along with optimising drivability, to worry about proving his abilities with nice graphs, to folk on the Internet
HD TV ? Another pointless gimmick sold to the masses as a “must have” in their lives. I believe we do have it, but don’t take my word for it, you’re very welcome to head over the pond and see for yourself, after all we wouldn’t want anyone thinking you guys are parochial

How well did that work out for the Germans in WW2?

I've been testing / tuning / building longer than 996 engine has existed, and I've always shared full details, including dyno graphs. I leaned a long time ago dealing with folks who always want to play the "smoke and mirrors" game, just let your work speak for itself, be damned what the other guy might post or say.
There's always going to be someone cheaper, someone with a higher number, someone with a cuter girlfriend, a bigger house, larger bank account, smarter kids....... so what? 7.888 billion people on the planet, ye'aint gonna win them all.
Add it to the top!! Note: Alternator was dropping from 13.8v to 10.5v arounds 6k rpms. Getting that resolved plus doing some other thing to get Air Conditioning working thru the Haltech and retune. Fully built K24 on low boost. Great street car power and fun to drive.

Nice man ! Happy to see the progression and from the looks of it, the thing must be a hoot.
