Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Dtec Tuning Duratec Heat Shield...it's ready!

Sorry guys I guess we were not clear enough on our web page..shipping on the shields runs $8.00 in addition to the price of the shield. When you click the "buy me" link the price w/shipping is shown. We'll be able to fix the link later today after work so that it's clearer.

We decided to initaly offer the non-ceramic coated shield to help lower the price a bit - that unit is $49.99 plus the $8.00 shipping bringing the total to $57.99 shipped via UPS Ground.

Thanks for all the interest! We're pretty psyched to see these on peoples cars.

i really really want one, im just broke. ill probably get one for the summer, as im sure im gonna have heatsoak

Is the Cougar hood and Contour hood similar enough in 'contour' that the same shield will fully seal against the hood along all three sides?

Looks awesome guys. I was going to make my own but it seems a fair price for what you get. I will be getting one come spring, not in the budget right now as I just bought an exhaust and it being 10 degree's out its not necessary.

Btw, might wanna get that beer bottle out of the pic.

yeah price is heavy but it looks liek a nicely built and functional prodct, ill get one once i get some money together. hey what abotu a GB on these that might bring the price down.

Looks nicely constructed, but I have a couple of questions.
Now I'm not knocking the product or idea, but I am going to ask pointed questions about functionality, then finish off with a recommendation.

Since you block off the area around the filter, what is the advantage over an SVT airbox that draws cold air from the fender?
The hole in the fender would be the maximum size hole that you could draw from and would be the most restricted point of the airflow path. A cold air line would just be a hose stuck through the same hole I take it and further reducing the area of the hole?
This isn't to say that it is bad since the stock SVT can make 200 HP off of the air through that hole. When I first put my 3L together I was able to hit 207wHP with the stock air filter box and a drop in K&N, but that was a 3L sucking air through it and it definitely improved it to go open air element.

I would say that it is an improvement over non-svt airboxes, and cold air is definitely better. The size of the chamber is bigger than the enclosed area of the svt airbox, so that is also better. But in the end at full throttle and high rpm it still draws air through the fender and it is still a restriction. Granted its cheaper than a new SVT airbox.
If you widen out that fender hole, then it will improve it I think.

I think the point is that if you completely seal up the area around the open element filter, where is the air coming from? Would seem to come back from the fender again.

Thanks for the compliments everyone! We've been working on this thing for a while now and we're pretty confident it works as advertised.

To answer Tom's (warmonger) questions:

As to the heat shield being a restriction -
The heat shield like I mentioned in my first post is sealed on four sides, but open on the fender side. I think I should clarify that the heat shield does not have an air tight seal with the fender/fender draw. Due to variances in MAF and intake tube setups between the SVT, normal Duratec, and aftermarket ones available (BAT, CTA) we decided to leave some space between the fender and the shield. We had to make sure it would fit a majority of the set-ups out there. The gap is mostly on the front and rear sides which are pretty well shielded by the fuse box and drivers side shock tower. This allows plenty of air to reach the filter but our temp testing shows a majority of it seems to be from the fender draw.
Here's a pic that shows the gap I'm talking about.

Having the bottom sealed is the key as the hot wash from the radiator fans and other hot engine bay components is blocked.
Again, as mentioned earlier a cold air tube makes this setup even more effective. Opening the fender up would be a good idea, but I'm warry of recommending it as it's not easy for most people to accomplish and the possiblity to do more damage than good is there. I'll let others experiment with this.

As to why our setup is better than the SVT setup - it allows the use of a better breathing, larger area filter. The stock SVT system is nice but the stock filter size is too small. Our heat shield allows the use of a larger better breathing aftermarket filter without having to deal with boggy throttle response when the radiator fans kick on and wash hot air right at the filter or temps climb.

As to high RPM HP loss, I was also concerned that enclosing the filter too much would hurt. The original prototype used a more open design for just this reason. But back to back testing has shown no loss in performance with the final version and better temprature control esp. when speeds are slow (i.e. traffic).

Thanks for the comments - keep them coming!

great work. so is there any problem with closing the hood. i ask cuz the shield seems kinda big (maybe its just the pic). so its low enough that its not really pushing on the hood and just seals to the hood? the ceramic coating is put on the outside of the shield correct? is it available in different colors or do u think the coating can be covered if i were to paint it.
