Looks great Chris... (IMG:style_emoticons/default/aktion035.gif)

If this is installed, would the engine tin still be needed?

It looks great. Any plans to test it against a horizontal fan DTM style shroud? I would be curious to see the cooling capacity over stock and DTM configurations and if there is any additional HP losses.

Great, just great. I've been fantasizing about a set up like this for the 914 turbo motor. I'm gonna have to give you a call here...

For a street car - yes, a race car - no.
Our kit will include aluminum sheetmetal to seal the engine compartment.

Comparative tests will be done over time.
With the new shroud design I am able to improve airflow by more than 10% over what I ran previously, ensuring even better pressure under the shroud for larger displacement engines.

There will be a 4 channel digital CHT gauge on this engine to accurately monitor of head temps, just like in the race car.

I am confident the hp losses are similar.

They used flat fans in more than one application. Most notably on the 917 engines.

Does look good (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/aktion035.gif) , alternator change would be a snap . What about alternator cooling ?? Oil filter appears to be relocated , spark plug change ?? What provisions for these areas ??Still overall aGR8 looking design , I do like it better (IMG:style_emoticons/default/w00t.gif) than DTM , more compact , have you any data on oil temps, head temps ??

I like the enginering...very Corvair ISH.

NOW, what about just adding an electric fan on top instead of robbing any HP off the motor?

RIGHT HERE! Is it possible????

Nice clean fan with the motor tucked inside, a pull design, smooth porsche gill over the top. ???? sorry, my .02 cents, free too!

With the necessarily high tension on the belts at the end of that long extension on the end of the crank, how's the side loading on both the snout of the crank and the #4 main bearing?

Very cool! When will this be on a six. (IMG:style_emoticons/default/popcorn[1].gif)

Actually no hurry. I got a list of stuff I would like you to do to my car for the next few years.

No, the electric fan isn't used for cooling, it's used to turbo the intake.

Seriously, energy isn't free- even when it's electrical.

That electric fan will either draw power from the alternator or from a battery pack- both of which which will drag down the HP.

Chris, looks good, can't wait for cooling numbers.

Don't think that an electric motor driven fan will move enough air.

Look very good Chris. How long and how many race miles do you think you have on this system?

I will never forget the time a flared 914 rolled in here and the guy told us that he wanted more power. We lifted the lid and lo and behold a corvair engine! Before I could say "sorry we do not work on corvair engines" an old mechanic I had working for me at the time said "sure we can do it for you!" Well Chris for the next year and a half he was modifying and building this bandit corvair engine for the guy, taking up WAY too much shop space and wasting HUNDREDS of labor hours that we could have devoted to 914 engines! That cooling fan belt arrangement reminded me of that engine. It ended up having so much power that it would constantly spin off the 90 degree belt from the setup. Looks like you have corrected it by installing TWO pulleys!!!!

An electric fan costs you just the same amount of power by making the alternator work harder.
Plus, you would still have to figure out how to make it turn in sync with the rpm, otherwise you overcool at low rpm ...

No gain there ...

The Cap'n

The tension isn't any higher than any alternator belt.
Not only that, my pulley isn't as far away from the #4 bearing as the factory pulley.
