The problem w/ trying to get the "Look" down is you HAVE to be done 1/2 way up the hood. On the Lotus and the GT40 the vents extend alomst to the windshield.

As far as the look, no you cant get the GT40 look to be right... thought about it for a while...


This is what i'll be doing...

Hood Vents

Pretty simple... Very cool

Bada-Bing! This is exactly what I had in mind. I knew it would be possible using the techniques for building sub enclosures and flowing/blending shapes. I will probably use wood templates for shapes so they are absolutely equal side to side and a little more rigid than wire for mounting while forming. Thanks for that link, I just needed to see someone else doing it first......

I personally do not like venting through the wheel wells for the aformentioned reasons. The really big reason for me is at extreme speed, the air venting via wheel wells or down from the trunk will most definetly create lift. My car is capable of insane speeds...so I created a GT40 style air tunnel venting hot radiator air out of the hood and, equally important, this design creates a huge amount of downforce at speed. Randy Beck (son of Chuck Beck 550 Spyder fame) raced a 914/6 (normally aspirated 300HP) and outhandled and outdrove 99% of the competition (read 911 twin turbos and such). Yes he races against some cars sporting over 700HP! He explained to me that his tunnel (built only for aerodynamic downforce) allowed him to stick it to everyone in the corners. I've seen the car on the track and it is so stuck down you'd swear it had a suck fan installed somewhere! Anyway, Randy told me a few years ago that I should copy his design and use it on my 914LS6 V-8 car. He even gave me a diffuser mold from his car to use on my A.I.R fibreglass hood. I cut the reinforcement ribs on the backside of the hood, cut a hole to the correct dimension, glassed the reinforcement rib structure back together, glassed the aero diffuser on top of the hood and blended it, created a separate removable fibreglass tunnel piece...and the pictures do a better job of describing it. It took a bunch of time and effort...but it works awesome. I have a 3 core aluminum Fluidyne custom radiator w/ twin fans. On most normal days (60-85 degrees) my car will never top 180 degrees. On one muggy 100 degree day I sat still in a backed up traffic jam for 30 minutes (no airflow) and calmly noticed my temp guage reading 190. I drove to Indy last year for the F1 debacle and never saw the temp go over 180 (even in Chicago rush hour). I run a stock LS1/6 water pump in the normal location and have cut out a hole in the firewall to allow it to protrude through into the cockpit. A custom fibreglass cover is installed over it and can be removed for access. I spent 7 years working on this car and I'll admit that it took alot of work to get it this far. I know Brad Mayeur and believe he's trying to put together a real nice sleeper. If this is the case, I would bet he's not in a real hurry to start cutting holes in the hood. It is true that when you make a system like mine or the other hood venting guys out there...you run a higher risk of rain water ingestion. I try to avoid driving my car in the rain and so far I managed to avoid it. However, I should think about sealing everything tighter than a drum and have a provision to direct & drain water out. I'm planning on driving my car out to Portland for the 914 get together and I can pretty well bet I'll get wet a few times.

Hood venting is effective, cool, and creates downforce at speed. How can you go wrong with that?

Bill

Two 500-700hp race V8 914's here in the Bay Area are exhausting at the hood. Chris Julian will follow suit with his beast...

And BTW, when a hood vent like that has sealed ducting, you can keep water out of the trunk (what's left of it (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) ).
My car gets driven in the rain, and venting the fender wells with open holes where the tires fling water in is a concern.
Thanks for posting Bill.

Bill,
Very nice! (IMG:http://www.914world.com/bbs2/html/emoticons/drooley.gif)

Is that a Sheridan front end piece? I really like what you have done with your teener. I sent you a PM with a few questions.....

that's exactly what i had in mind for mine, except, i'll cut around what i marked green in the pic and attach that part to the hood.
the endresult is the exact same duct when the hood is closed, but leaves me with access to the front trunk area underneath when the hood is open ...

Thanks guys, I didn't expect this much information this soon. Cutting the wheelhouse is a proven way to keep cool and probably the best solution. I will probably end up doing my outlets that way but I would like to explore alternatives.
I am looking at alternatives because:
!. The front compartment gets really filthy in a short period of time.
2. This is an area that is part of the "crush zone" I have seen many wrecked 914's in the past 34 years and the inner wheelhouse is usually crumpled even in a fairly light crash.
3. I have no proof or experience but it seems cutting up into the curved area
of the wheelhouse would affect the ridigity of the front end in regards to handling. I'm sure many of you V8 guys have driven a 914 at least as hard as I have, any input on this, any before and after experiences?
4. Probably not a factor but when we "restored" the V8 car back to stock, the wheelhouse was the most difficult to area to address.
Thanks again on your input. Brad

That's similar to Elephant Racings hood vent installed on a FG lid

Nice study on aerodynamics too...
