I have heard the conventional wisdom that "you can't turbocharge a type 4 successfully." Is it just difficult, or can it really not be done well? I'm tossing around the crazy idea of turbo'ing a type 4 for PCA club racing, to put in the chassis in my avatar. My 6 in its current configuration is not competitive, so I can put a bunch of money in that, or do something different. I like a challenge, so why wouldn't the following work?
- 1.8 or 2.0 type 4 as a base. I would keep displacement stock or close to it. - EFI for induction - Properly sized intercooler and huge oil cooler - A good aftermarket cooling fan - Would be dry sumped - I would work with a knowledgeable builder or shop to build the engine. I am not so familiar with type 4 race modifications, but presumably this would include reinforcing the bottom end, using Carrillo, Pauter, etc. rods - Obviously the heads would need to be reworked for flow and possibly reliability If I do the above, could a type 4 be built to withstand 15 psi of boost and make 350 hp reliably?

Scott, what limits do you have on engine controls? I'm just wondering if you could extend engine life with some fancier fuel/timing/boost control strategies based on EGTs, knock, etc.

I'm just wondering if you could extend engine life with some fancier fuel/timing/boost control strategies based on EGTs, knock, etc. How about water mist cooling like some if the 911 guys have done? I think is called Coleman water cooling or something like that. Good for 10 to 15 minutes? |

I'm just wondering if you could extend engine life with some fancier fuel/timing/boost control strategies based on EGTs, knock, etc. No limits, at least not in the rulebook (IMG:style_emoticons/default/smile.gif) I don't have a bottomless wallet, but I would plan to use a quality engine management system if I do this project. How about water mist cooling like some if the 911 guys have done? I think is called Coleman water cooling or something like that. Good for 10 to 15 minutes? I thought of this too. I believe it has been called the Rubbermaid solution for the brand name of the container you put the water in (IMG:style_emoticons/default/smile.gif). Popularized by a 914 guy, no less - Grady Clay, RIP. He used it on 911 motors at the track, and I assume on his 914/6 racecar. I imagine you have to decide if you heart is into the project or the driving. Yes, you've got me on that one. If I didn't like a challenge, I would not still be racing the 914. I'd have bought a spec Boxster! |
