    The article presents the officially listed lower HP and torque figures for the Stratos but most think that this was meant to simply appease Enzo who wasn't keen at all on supplying engines to Lancia. It was only after pressure from Fiat and Lancia threatening that they'd go with Maserati that Enzo agreed. The Stratos has a better induction system (replicated by some Dino owners) so if there are differences in engine output they are probably in Lancia's favor.

    The Dino in the article looks spectacular. Such a beautiful color...

    Image Unavailable, Please Login I installed an NOS Stratos induction system on my Dino. The bottom end all the way to cam profiles and heads are identical to the Stratos Stradale. The performance and drivability with the Stratos IDF’s vs the Dino’s DCNF’s is huge! The DCNF’s were a compromise. They were designed to be compact and mounted in a north-south motor orientation vs transverse. I solved this with the IDF’s and a special “lowered” airbox with a ram effect. Much improved throttle response and no fuel starvation with the Stratos setup. It transforms the Dino! Completely bolt in w/o any mods to the Dino! Fits under the stock decklid without any mods!

    I had followed this in the Dino section. Really is a great set up. Will likely do the same thing at some point if I can find the carbs. The airbox will be a whole other challenge.

    There is a site that still shows a set of the carbs for sale if you are interested. I am told they are rebuilt but look like new in the pictures.

    It’s also possible to use the new IDF’s. They have a different casting for the fuel intakes that makes the carbs sit a bit wider. Jon Gunderson has a non-factory Stratos intake that was cast in Italy that is surplus to his needs (see photos). He also has 3 new IDF’s for it. The intake manifold is a bit different than the OEM one that I have. The first part is finding the parts. The hard part of the airbox was experimenting and mocking up. I have no problem sharing what I’ve learned. If I could find a used stock airbox (even a rough one!), I want to see if I could subtly modify it to fit without raising the decklid.

    very cool airbox... nicely done being period correct looking.

    too bad there isnt much room for longer stacks since the drivetrain is so tall and the decklid is low. the whole intake track would benefit from being longer i reckon. im puzzle on how you are getting ram effect with your set up? not sure if you can get any significant pressure with carbs or with that airbox set up. nevertheless, love this mod you have done.

    Believe it or not but it runs better with the short stacks. I experimented with different lengths and profiles. The stock Stratos Stradale airbox is quite short and has no velocity stacks. It only has plates to smooth out the airflow. The Stratos Group 4 airbox is really large and allows really tall velocity stacks which is a different case altogether. I am fully satisfied by the overall power and drivability that we arrived at. The goal was no irreversible mods to the Dino.

    oh i believe it, often times you have to experiment on running cars. the size/shape of the airbox in relationship to location of the stack openings at times determine the resonances of the whole intake system. there are so many factors contributing to the reflective waves and its amplitude. cool that you made it all work, but mostly impressed by period correct fabrication and the factory like appearance.

    Thank you. We did many mockups and Lots of road testing. The filter is stock Stratos/308 (I used a K&N cleanable element). You can see the custom mushroom shape air horn I designed and rapid prototyped. They worked and flowed well but I ended up liking the short velocity stacks better. They were a bit “snappier” in response.

    brilliant job on the radius short stacks.

    i always thought that would be a great set up too for the 308 since IDF/IDA manifolds and carbs are available. to increase the volume and filter area I thought you can build a spacer/retainer ring to you can stack a pair of filters on top of each other and space out top lid up. easier with the later model 308s over a dino since you can just modify the grill without sacrificing the a rare dino deck lid.

    how did you do the filter plates? photo etch or screen printed? they look wonderful

    I designed them with my collegue on Catia then rapid prototyped them with our printer. I can’t remember what type. Here’s a couple more images of them. The screen strainer upset the airflow but thought we’d just try it! The mushroom alone worked well but I found some super short velocity stacks that worked better. My friend Simon Leach tried them on a flow bench and found they were extremely effective.

    ^John your car is just exceptional. The stance. The color. The 'euro' details. Just a stunner, one of my favorite cars on this site. Bravo!

    Yeah, I did see it in some Tour Auto videos on youtube. The owner was going for it! Good for him/her.
