mTDI Mechanical TDI Conversions / Re: Thoughts on mTDI AHU head porting
« Last post by RabbitJockey on February 13, 2024, 06:52:00 pm »
there is the swirl bump but there is also another one closer to the valve seat that is there to help prevent cracking from the location of the injector.

If I were you I wouldn't port the head because it's time consuming and the benefits aren't really worth it for 110hp.

if i were going to do it in your scenario I'd focus on just smoothing everything out and not enlarging or changing the shape of anything. only use sand paper cartridges, no burrs. this would hopefully help to gain efficiency with out losing any low speed power. Also definitely get a PD style intake, with the pd intake and very very mild porting it should run cooler and smoother.

Thank you for the replies. As far as HP and torque goals are concerned. I am looking at maybe 110HP out of this. Remember it is going into a vehicle with the aerodynamics of a brick and heavy. I kept the K14 because of it's early spooling throughout the rev range and I plan on not allowing it to go above 18PSI. I understand that I can get much more HP and torque with the LR IP but, once again, heavy brick. I am aware of the swirl bump in the intake ports, which assists with atomization of the fuel and air. My plan is to smooth it a bit, but from my understanding, the more it's reduced, the more the fuel just get dumped into the chamber and less efficient atomizaton, more heat, more black smoke. I also understand that the exhaust ports should remain smaller and it seems like that step from the head to the exhaust manifold allows the hot air to move quicker to the exducer, creating quicker spooling response. So with that information, port matching the exhaust ports may not be the ideal scenario. And smoothing out the intake chambers (opening up the bowls), grinding down the valve stems, and opening up the D ports, plus using some grinding paste on the valve seats and valves seems like the best option. What do we think?

Would that be the one that resembles an aircraft hanger?

I wouldn’t have the room to Park that many. Have to borrow a spot now as it is from the neighbor and only have three vehicles.

Still have 7 VWs in different form... Keeping them. 2 diesel powered 96 GTD, and 79 Rabbit with a TD.

Time to buy one of those 12,000-dollar fixed-up, swapped-out, lowered, and detailed VWs you can find in the Marketplace or Craigslist. 

Or just one of those 2,500-dollar ones and fix on it yerself.

I'm down to 1 vw and it only gets driven during warmer non snowy weather nowadays. 10 years of NewEngland winters have taken its toll on the body of the Vw.

ok, that's not a hole.
 just a low spot where some of the black paint survived.
Not there on the 1.6.
