Just rolled into the driveway from a 70 mile trip back from McMark's Original Customs Shop in Napa... Wow. I left Mark's shop at about 4:30pm so I knew I was going to get some traffic. But magically, it was sporadic and I just cruised. This motor just never ceases to amaze me. 5th gear passes are no problem. The power is everywhere. Not peaky at all. just pulls from the bottom to the top. I love this motor!!!
I think my motor is a similar combo to Dave Hunt. He has Nickies which are actually good for a little power in addition to better cooling. I will be working out some details over the winter which will be small stuff at best. Possibly an external oil cooler. Though, I have to tell you guys this again, this motor runs cooler than my stock 2.0 liter. I strongly recommend the 2270 Raby kit. Build it yourself or have Mark do it. He has a couple of them under his belt now. This is the motor VW-Porsche should have used. |

I keep reading all about the Raby engine and I sure wish that there was one up here in Pa.I really would like to be able to keep up with the 911 going up the small mountains we have here in Pa.(I have to let my wife go first up the hills in the 911)
I was told by one of the local guys for $5000 I can get you to between 140hp to 145hp. Hmmm I must do more due diligence on this ...I need more power. I need to see about building one myself....I think I can , I think I can do it. |

Hmmm I must do more due diligence on this ...I need more power. I need to see about building one myself....I think I can , I think I can do it. The kit will get you more power than that. Plus many of the engines out there that put more HP into the Type IV actually are so poorly designed that they are undriveable. Too peaky, run too hot, self-destruct in no time. I am not saying that Mr. Raby is the only Type IV engine builder/designer on earth but his testing is right out here in front of God and everybody. If he messes up, his pants will be down around his ankles right in front of all of us... I worked in a Porsche shop as an undergrad and the owner used to build "disposible" motors for his ice race 914. All you have to do to make more power is BIG cylinders and pistons with BIG compression and a peaky cam. It will not last. But it will make bigger numbers on a dyno. Problem is you don't drive on a dyno. Last I checked the real world was outside. This engine was designed for the real world. You will not grow to hate this motor. That is more important than many people realize. There are really only two complicated processes involved. One is the Deck Height Measurements, the other is Valve Train Geometry. Both have technical articals posted by Jake on his site. I had a Mark with me so this was infinately less painful for me than others. For one thing, he had the tools. For another, he has done this many times with his $5000 dollar motors. I said this before but it bears repeating, this is the motor that VW-Porsche should have used. This is such a fun car now. I cannot wait for next autocross season. Even Trekkor thinks I should take it to the track. Depending on what 911 we are talking about and just how open the road is, your wife may see nothing but taillights if you built this motor... (IMG:style_emoticons/default/driving.gif) |

That is more important than many people realize. That is an excellent post Rob! Often people look for a dyno queen engine! (peak hp sucks if you only get it on the last 200 rpm you got!) I am now more seriously considering this option to my feebly powered 1.8L. After reading Jake's posts and website info, it seems like he is the type of straight shooter one would want to deal with as an engine builder. Working and devoloping one specific engine platform...and definetly showing pride in it is never a bad thing! I would like to hear some high mileage testimonials (not that I doubt the reliability, but it is always nice to hear!). |

Working and devoloping one specific engine platform...and definetly showing pride in it is never a bad thing! I would like to hear some high mileage testimonials (not that I doubt the reliability, but it is always nice to hear!). Eric, The first engine I ever built was a Type 1 VW for a car that was a daily driver while I was in college. I dropped a valve while photographing an ice race in Manitoba Canada and had to be tow barred back to Minnesota. It was a stock rebuild because I had no time to start thinking "as long as I am in there..." It turned out fine. The next engine was for my Toyota pickup. I had put 200K miles on it and it was tired. I was seduced by the higher compression pistons and the aftermarket cam, and headers. The truck was impossible to tune, the headers leaked. I think I struggled with it for a few months before parking it. Someone came along and offered me a trade for a motorcycle I recall... The lesson here is that unless the engine is designed as a system it is unlikely to work as a system. Jake does a bit of his own high mileage testimonial and testing. If you snoop around a bit, you will find that he builds an engine and runs it for 25K miles or so without an oil change or purposely tries to blow it up... Things you probably wouldn't do just to see that it will last. I expect that this engine will have great longevity as it runs noticeably cooler than the stock 2.0 liter. The kit is nice but really, what I was paying for was the testing that went into that combo. Jake knew exactly how that motor would act because he had built many or them. My particular combo is the same as an engine he built and put into a tired old Type 1 he called the Bluebonic Plague then drove from Georgia to California to an event called Bugorama. This event is held twice a year only 5 miles or so from my house. After driving across country fully data logging from the back seat he put in a couple drag race runs in the very respectable range and someone just bought the motor right out of the car! He had the car flat towed to Georgia and flew back if I recall correctly... The whole adventure was chronicalled on the internet. I think he even got out of a speeding ticket because the highway patrolman was a VW guy. The kit was so complete I remember emailing Jake to ask where the 6 pack was... Everything else I needed was in there! (IMG:style_emoticons/default/beer3.gif) If Jake moves ahead with the kit program as he has described, all you would need is basic hand tools and a torque wrench to do this kit. The old video is good but had it's weeknesses especially as it concerned the two complex processes. If Jake makes a new one, it would be likely to specifically address the kit build. The other was part of a series called "Bug me". There is some level of personal responsibility involved. Let's face it. You are stepping outside your comfort zone when you build a motor. If you don't follow the directions as they are given, if you try to cut a corner or two, your result may not be what you wanted. At that point you really can only complain to the engine builder. That would of course be you... If this had been the engine VW-Porsche put in the car in the first place you would be able to buy a 2008 914. Probably watercooled but you get my point.
