Turbo for a 914..., this may work Options

[spare time toys]

Check www.ststurbo.com they put it away from the engine. I would think it would have a big turbo lag. (IMG:style_emoticons/default/huh.gif)

Special heads?? Like these?

Those will be available in late 2005. Turbocharging will have a whole new meaning with these puppies, since they use a far superior exhaust port design- from a Type I!

The cooling issues are heavily dependant upon the engine combination as much as the cooling system.

I will tell you now that I have done ALL the R&D work on the Nickies cylinders and used more than anyone on this planet. These engines run super cool for many reasons including the fact that due to drastically reduced friction from the Nikisil that not as much heat is generated. The cylinders also act as huge heat sinks and actually suck the heat right out of the heads!

I have done back to back Nickies/ Cast iron testing on the same engine and saw drastic differences in temperatures, almost 75 degrees at full load for a 40 minute test at 4800 RPM. With the cast iron cylinders that test could not even be completed due to heat soak and what I'm sure would have ended up as a dead engine if I would have kept the throttle pinned.

Porsche knew what the limit was before the cylinders heat soaked and that was around 18HP per cylinder. This is why they went to aluminum, nikisil cylinders themselves. The cylinders make a huge difference after the throtle is held wide open and load is held steady. When testing with cast iron cylinders the head temps and cylinder temps will soar and never really level off with high HP (over the 18HP per cylinder rule) With the Nickies this is a different story, especially after the point where the cast cylinders heat soak. Here is a link from one Type I engine I tested so you can read about some results and some heat soak. This was not the worlds best test because I goofed up the combo and the engine lacked power to really see the nickies do their best. I never really got high enough on the HP chart to max out the cast iron cylinders with my cooling system on this one, but it is interesting. More tests like this have been done, but I have not had time to post the information to the site..

Here is a link from my site from a customer that has a 201BHP N/A engine of mine. These temps are 50 degrees cooler than that of a STOCK 2.0 engine! Its a 2563 TIV...

Also here is another from a customer with a 2739cc, 240 BHP N/A engine with Nickies in his beetle. His head temps run in the neighborhood of 25 degrees hotter than the 2563 link above. This engine has 10.3:1 CR and runs on pump gas.

Here is a link to my "Super Hero" page for the 914 crowd.... It has some more Nickies information there.

The other thing that both these engines have is my cooling system, which keeps all the cylinders very close in temperature compared to the stock arrangement. The 914 version of the cooling system is being developed as we speak.
