Rolling Thunder!, 2270 Raby Kit Rocks! Options

[ConeDodger]

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.

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 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!).
