After all these years man
Glad to see you guys still at it

Shop looks like a movie set. Badass.

John, you and the team at Powerhaus keep making impressive engines.  Don’t stop doing what you do and keep the R&D (research and development) going to make your engines stronger and more efficient.

Enjoy your vids and the info. Thanks for spending your time posting the vids.

The 40 hp was unchanged for 5 years.  It was also the last 30 mpg air cooled VW.  45 years ago I had a souped up '64.  These days I have a '64 with a bone stock 40 hp.  Pure joy for me.  If it doesn't do 72 mph, tune up time!  Cheers!

I want one those bid engines some day for sure!

+1 .. Wow,,, A Powerhaus VW motor would sure walk up our original 1979 Super Beetle Cabriolet .. The 1600cc makes an impressive 49HP sans the Calif CAT converter of the day..  100HP plus a torque increase would do wonders for drivability ....

Another impressive vid of impressive engines. Thanks for the details 👏👏

Fantastic videos guys!.. I look forward to new ones...

On the aluminum pushrods, I would just tell you the the linear coefficient of expansion is greater than for steel, so it's not that the steel pushrods expand more slowly, but they just expand less.  If you were to measure them at ambient air temperatures, than heat them both in an oven to any temperature you want, and measured them after heating them up you would see that the aluminum would be longer at any given temperature, no matter how long you heated them in the oven.  I am not a fan of the steel pushrods because of this.  Having said that, I have also run all of the aluminum pushrods on the market and bent all of them but one.  The only one that has survived for me are the JP Motorsports Sweden 7075 aluminum pushrods.  I have them running on an engine with the JP Motorsports MS250 cylinder heads with dual springs and 1.6 to 1 ratio rockers at 8,000 rpm with no issues, and .04 lash like stock.  Nice and quite valve train with more consistent valve lash regardless of the current operating temperature of the engine.  They are not cheap, but they would work for any engine I have seen you guys build.  This comment is not to be a criticism, but just to let you know my experience.  The steel pushrods work fine, you just don't get consistent valve lash across all temperatures, and if course most of the aluminum pushrods on the market are not strong enough.

Wish They could work on My 964 engine !!! VW 💪💪

Very,good...

Awesome I would love to put one of those in my 74 Street legal Baja

Cool video

What's the largest you can make a VW engine, without losing the FWEEP?

Can you make a video on what kind of modifications needs to be done on the engine bay to make fit one of yours 2100 cc. I want it to know so I can buy one from you. Thanks

I need a air cooled motor for my 86 cabby please help
