While trying to make the jigs to drill my heads for twin plugs I ran into a
major problem. Where is the plug going to be located on the bottom of the head. I made up this jig to located where the plug will be located. Angle jig Test jig installed Installed Bottom view |

Jake. I am bound by circumstance to butcher for my speed fix.
I have to admit it, the only real reason i am shying away from a big power Type IV or a 6 cylinder Porsche motor is simply due to cost. Instead of wasting anyones time talking, thinking I just know I can not afford it. I am ok with that, but still love to see them. I see the merits in staying air cooled for simplicity and can see serious power. 274hp at atmospheric pressure out of an air cooled type IV is insane. You are now almost at 100hp/l and that is a type IV. Not a honda cylinder head. To give you an idea the 2.7l stroker/bored out K series honda guys are getting to 300whp just now with a very well though out port design, electronic cam phasing, and very well thought out internals. On a motor i dont know, 40+ years newer. But, I look at it from my single income wife/kids perspective and it is just out of my reach, at least at this time. I know it takes a lot of quality materials, and R&D to achieve those results and thus why it costs so much. I also know there is no compromising getting those results from something like a type IV. Thus, no big power type IV for me. I think a lot of others are in the same boat. But to those of you doing big stuff with Type IV motors, I salute you. It is 100% totally rad and respectable. I hope to one day be in that spot to have something like giant displacement type IV with a 30R attached to it. But for now, I have commitments to my family and children that chew through money, energy cost spikes and inflation make it worse. To the OP(904 SVO): If you decide to go turbo, Precision's new billet wheel turbos are the bees knees. They get rid of the poor flowing Garrett wheels, and basically just use the CHRA with their own flavor of bearings, if you go the ball bearing route. They will make equivalent or more power with better spool than a Garrett GT series, cost less, and I believe are made here. Garrett stuff is all chinese/mexinese now. That or Borg Warner Bullseye makes some very nice stuff. They are more like a mitsu design, with the extended tip stuff. They are also very cheap to rebuild. |
