I want to improve the aerodynamics of my F512GTB (F355 with 512 tr engine / transmission). First I bought a Imola Spoiler after a long search. Underneath I build Universal Flaps. At the side I build flaps of MB, which are modified. At the rear, the rear grill is sawn and a grid is inserted. Everything then painted in black. At the back we built a universal diffuser. With my F512GTB is space for, because at the 512 tr the transmission is under the engine and is not behind the engine, as with the F355. Now I'm looking for a Tubi Style rear wing, only I have not found a picture as the Tubi Style rear wing attached to the F355 looks. Does anyone have a picture? Does anyone sell a Tubi Style rear wing? Other rear wing ideas that are affordable and look good? A universal rear spoiler lip is also glued on. The last problem is the front grille. He does not have a real radiator front, but only left and right cool air for the brakes. The air can not flow optimally through the grille. Either I put a Plexiglas disk in front of it and leave only holes for the cooling air of the brakes open, or I build a large wide hole to guide the air up through a hole through the hood. Is this only more pressure or is it only useful if you install an additional radiator in the front? Your ideas?

Here's the link to it on eurospares Ferrari 355 Challenge (1999) - Rear Wing: Page 005 | Order Online Eurospares
Thank you for the picture with the tubi style spoiler. Now I know how it looks. I know that Eurospares sell them but the have no picture how it looks at the car. I found this one but they make no international transport: NEW GENUINE TUBI STYLE FERRARI 348 REAR SPOILER PART TS5436 | eBay
Tim, really impressed with your car and your project. Looks absolutely fantastic. You've probably covered this elsewhere, so sorry, but what are the aero improvements (outcomes) you plan to achieve? I ask because I am slowly approaching something similar, and am looking at pay off between aero aids in terms of weight (even CF), drag and benefits only available at certain speeds. At the moment chatting to a couple of colleges to see if they have any students interested in a project! In terms of the A/Con, how hot and under what circumstances is it not performing (over heating?). I'd have thought an exit point for hot air would not need to be too large and could create a 'draw' effect? Your plexiglass protector would be 'inline' I assume of a dedicated channel? If only you had a big fan and some smoke bombs!! (Or a bunch of college kids). Feel free to PM. Stu Sent from my iPhone using Tapatalk
StuR ????? I have seen at my Maranello the aerodynamik problems when the number plate is not high enough assemled. You cannot drive more then 230km/h. Image Unavailable, Please Login
I think I used to dream of driving my mondial when first bought for 230km in terms of distance, let alone speed!!!! Aside from speed humps I imagine the front engine cooling and disruption to undercar airflow at that speed could be quite affected. Sent from my iPhone using Tapatalk
I drive with both Ferraris till 315km/h....I know that many F355GTS crashed when they drive fast without the Targa Roof, because of aerodynamic problems at high speed. My F355 has 80kg more weight at he back but the transmission under the motor and not after the motor like the F355 and about 470PS. So I drive here in Germany very fast, not only on highway....normal Streets till 250km/h
I thought you mentioned in the past this was a stock spec 512tr engine. How did you get another 50hp out of it since?
Polished intake valves and intake ducts, optimized timing, increased compression and improved engine software direct from Ferrari, BMC air filter, tubi style exhaust without cat...
More compression~ Any running hot issues? With all that stuff shoe horned in the back you get enough air flow?
He gets enough cooling air to have a low cooling temperature at full throttle on the highway. The theme here is to improve the aerodynamic of the F355 Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
So given the rear window buttress, the extra rear weight and the mods done to the racing 355s, is it largely about front splitters, possible winglets and a smoothing of the rear airflow? The advancement over 348 underflow might be moved on with a diffuser, but I assume the road use rules out any real side skirt issues/benefits. Sent from my iPhone using Tapatalk
The big problem is to get more downforce at the front. The Imola spoiler and the flaps are a beginning. Ferraris are unfortunately developed without front number plate in the wind tunnel.
So, On the 355 I assume you've logged the incremental effects of the 'aids' you've incorporated so far, and front end stability remains an area for improvement. I don't know the EU/German limits for front splitters, but I imagine you could go some way further (don't want to mention the 'P' word, but their pretty good at dealing with rear heavy cars that can be twitchy! You have the challenge ducts fitted(?), so front brake cooling is directed. So you could remodel a lightweight front for better flow. I'd simply remove the A/C and solve the cooling/air flow issue (free up a bit of the power - you could even add front weight that's more balanced than the RAS and still have more bhp/T !). I think for what you're proposing you might as well look at repositioning the A/C rad to make it more balanced (sorry, am assuming it's offset like the Mondi) and able to be in an airflow that doses the risk destabilising the centreline by having a different pressure over/ one side. Wing mirror changes and smoothing frontal bonnet/light pod gaps will also help with improving the aero, but the aesthetics might not be great? I would smooth the rear flow over the engine bay as that'll improve the diffusers ability to create downforce (plus a lexi 360/F40 lid will show off the redheads a treat!)

When I drive fast at normal streets, I drive alone....so I must make alone the picture...over 200km/h it get dangerous sorry.... I like to make race with fast Ferraris or motorcycles. At little streets with very muc curve I can drive 3-4 gear till 200km/h. The motorcycles driver do not believe that a car can drive so fast...

Sorry I do not understand your englisch an when I take google translate, I understand only stupid things..... The question is if a whole in the cooler and front hood brings downforce? With this car I have not so much Limits because it is a oneOff car with special papers!

Sorry Tim mines a long post. Is the modded GT in the pics yours? Or are you looking to replicate? I don't understand why you need to improve stock air con cooling, unless you are saying the speeds you drive at causes air to build up due to restrictions? You can make a vent in the bonnet to release air to aid cooling. But you'd be as well blocking the front for aerodynamic benefits and removing the aircon. In terms of improving aero: bigger splitter than shown; smoothed bonnet shut lines/gaps; thinner/smaller wing mirrors; 360 style rear hatchback. Hope this is clearer.... good luck with the car.
