Oh yeah. There are a lot of changes. i see it now. I like the front a lot...the part where it angles over the headlights...subtle but aggressive.

The vent delete does help make it look stretched. But isnt that vent kind of important for something? Isnt that the AC intake where it goes through a cabin filter? Well, if you have survived with out one for so long I guess its not critical.

I like the vent delete the most. I didn't even notice that before.

My favorite body modifications are the ones you barely notice.. ones that clean up the lines, or accentuate them.. not bastardize them.

Seriously man.. looks awesome!

Yea thats what I go for subtle but aggressive. I dont like if someone has never seen the OEM bodystyle for them to say "I like what you did with the hood." I want it to look like it came from the dealership.

how about an oil cooler under the front center portion of the hood on top or just in front of the top of the Radiator. Make kidney grill inserts and rework that air plastic piece that went to the OEM air box to instead direct air straight through that oil cooler mounted right there under the hood. Have that air passing through the intercooler vent out a rectangular cut out in the hood. The oil cooler mounted at like a 45 degree angle and have a depression in the hood where the hood vent cut out lines up almost flush with the oil cooler.


kinda like this but further forward

Thanks for the feedback everyone. I'm making my final decision by 1pm tomorrow (Thursday). Here's the direction I'm leaning after evaluating everything. I'm not going to be able to please everyone on this hood so my goal is to get the highest percentage of people wanting to buy it. So keep that in mind. I want to meet all of the requirements I mentioned and provide the highest quality hood on the market. Based on the feedback I've received I think I'm "not" going to have any side vents in the hood. They don't serve any "real" aerodynamic benefit, they allow water to get into the engine bay unless you block them off which is a pain to do and negates the benefit, and manufacturers aren't putting them into high performance cars either. I like the powerdome idea but I prefer the recessed look. So I'm thinking of making the center powerdome area follow the same lines as it does on the factory M3 but recessing the center section like it is on the HPF M3 with a vent for cooling that can be closed up if necessary. I'm also considering smoothing the sharp edges on line that goes from the front corner of the windshield to the kidney grill.

This is your last chance to help us with your feedback so please let me know what you think. Thanks.

Chris.

Function is form. The manufactures aren't making 1000hp turbo kits either. Unless you want to compare a hpf car to a production car. The hood has to work from an engineering point of view. If it doesn't, it might as well be a sticker. This is just my opinion. You can drive without a hood in the rain. Is anyone buying this sh!t? If water could effect anything within your engine bay, everytime you drive in the rain you would be fvcked. Wake up!

Take a deep breath and let it out.

There would be two types I would buy...a style similar to the vorsteiner with an accented power dome...or a complete OEM style with improvements such as strength, weight, etc...lots of people would want a carbon fiber OEM replica as...well it's like the OEM version except better lol. I do not like the idea of a recessed area.

Then again...I hear two power domes > all

Chris,

Thanks for making this process public, and giving enthusiasts the chance to participate in the design process.

Whatever you decide on, I think the focus on quality is going to sell more units than how it looks over time.

Nice idea for the central radiator venting.

I had a vent with my old hood right over where the AEM is mounted, and in the rain, this would cause the car to act very strange.

Also, rain through vents gets your engine bay very dirty, pretty fast.

Didnt Vorstiener or one of the companies make rain COVERS for the vents?

I would really like to see plenty of louvers to vent out heat to keep COILS and those of us with SMG pumps. COOL. Engine heat is DEATH to SMG pumps. Will not vents help keep under hood temps much lower???

While I DO like the look of NO vents, the practicality outweighs so many things IMO.

It cant be that big of a deal to make covers for the vents that can be firmly secured, even while the car is moving in a big rain storm.... or parked outside in the rain.
Chris, will you consider this? make the covers OPTIONAL to keep the base price down.

It is another engineering obstacle, BUT necessary IMO!

If you dont put vents in I would not be interested in buying the hood.

Didnt Vorstiener or one of the companies make rain COVERS for the vents? Even with screens, I can see my engine bay totally filling up with debris. I dont have a garage and covering the car everytime is a HUGE PITA. But I could snap some hood louver covers on in a jiffy.

I would really like to see plenty of louvers to vent out heat to keep COILS and those of us with SMG pumps..... COOL. Engine heat is DEATH to SMG pumps. Coils LOVE cool air. Will not vents help keep under hood temps much lower???

How many people want to buy a performance hood for its COOLING effect? How many want to buy it for appearance only or simply weight reduction?

I dont know if an informal poll was taken for the main CRITERIA for wanting a performance hood...any performance hood. Everyone likely has a different reason. Mine is primarily is a significant under hood temperature reduction.
IDK what percentage that represents!

If you dont put vents in I MAY not be interested in buying the hood. It depends on the level of under hood COOLING.

Chris, you said: "So I'm thinking of making the center powerdome area follow the same lines as it does on the factory M3 but recessing the center section like it is on the HPF M3 with a vent for cooling that can be closed up if necessary."

I dont see how anything short of VENTS like the old Vorstiener hood is going to significantly reduce under hood temps.
Please convince me that I am wrong and I would be interested in your NON louvered version of the hood.

All I want is a significant under the hood temp drop. I don't care how it is done!!
To tell you the truth, I am not a huge fan of louvered vents from an appearance point of view.If you can attain the SAME temp drop using a different system than louvers, then bring it on! I dont see how, especially if the car is standing still.

Then you have sh!tty connectors/connections. That isn't a vented hood issue, it's electrical. I will leave my car running and power wash everything, if you are going through as much water as a commerical power washer can move. Your gonna need a bigger boat.

Washing the AEM is definately not recommended lol...and its common knowledge that the connectors on the first design are crap.

If your goal is to power wash your engine with after market electronics you'd better be using mil spec connectors... I wouldn't even power wash my engine if it was 100% oem.. I hand wash them gently.

I have seen and spoken to so many people over my lifetime that have done the same stupid thing with not so lucky results. ha ha. I don't think the manufacturers intended on the entire engine compartment being submerged in water.
