I had lunch and hung out with McMark and the Original Customs crew today and an interesting subject came up...
We've all heard the old joke about how you can't turbocharge a 914. In reality, it's been done many times. Mostly badly, but it's do-able. McMark's own car is a 1.7 turbo he built as a proof-of-concept and his build has worked so well, he practically daily drives it! I know most of you have no reference for what I'm about to say but I'll try to explain; driving a 2270 stroker TypeIV is a great big bowl full of fun. The flat torque-curve means you don't have to shift all the time, just put your foot down and go. No lug, just grunt! Driving McMark's 1.7 Turbo is like driving a 2270. That, and when I have driven it, it was only at about 6# of boost or less. Turn that up, and you've got a serious screamer on your hands... His execution is about the best I've ever seen (as per usual Original Customs fare). Yet, having very nicely proven the concept, McMark has only built one other turbo engine. What gives? You guys don't like the idea of a turbocharged 914? (IMG:style_emoticons/default/confused24.gif) Let's discuss this... |

Barrel to cylinder head flame rings, there are matching machined grooves cut into both cylinder heads and barrels . These were made at Aasco Machining. Ive held 21 psi boost with this set up.This design can be applied to the type 4 as well,
