KID IN A CANDY SHOP!

I've heard of turbocharged 348's, but I've never heard of a supercharged 348. There is very, very little room between the front of the engine and the fuel tank/firewall area on a 348 - not enough room for a belt/pulley system unless substantial modifications were made.

I think it would be easier to install a souped up Chevy V8.

 

I suppose you could supercharge just about any engine. But if you're asking if there is a ready made "kit" to supercharge the 348, the answer is no. If it was easy to do, someone else would have done it by now.

 

A turbo kit on a 348 would not comprise of "hot turbos(25+psi)" this is not a honda engine that can be thrown away, and the manufacturers of these kits understand that. If you are looking for forced induction I would recommend speaking to one of the site sponsors www.norwoodperformance.com . They make turbo kits for the 348 ranging from 5 to 15psi. There are many other companies out there that make kits another notable kit is made by www.koenig-specials.com they make an insane turbo kit for the 348 that is as large in price as it is in power. Anything you do will not be easy or cheap, and if it is raw power you are looking for I could not recommend buying any eight cylinder Ferrari. These cars were never meant to deliver mind blowing power and although it is possible to achieve ghastly amounts of power from them they would require constant maintenance and would not be suitable as a daily driver. If you would like to achieve optimum performance from any eight cylinder Ferrari, weight savings and suspension will bring the car far closer to its optimum state of being than forced induction. I don't mean to come across as rude and if you do buy a 348 I am sure you will find as I have that the community is one of the best out there, but if it is a hot rod you are looking for I suggest that is exactly what you should purchase because a 348 to be honest would truly disappoint you.

 

A supercharger is problematic for the reasons already discussed. I would aslo be concerned about running an S/C pulley off the belt that already does both banks, water pump, etc. These are interference engines so a broken belt = $$$$$.

Newer turbos with water cooling are very difficult to coke the bearings. I would recommend picking up Corky Bell's books on supercharging and turbocharging and comparing and contrasting the merits of both. For better low range power I think what you are looking to achieve is an increase in torque, not really more HP.

 

Back to business, so if you ultimately do go with supercharging I would look at getting the supercharger off of a Ford GT it is already designed for a similar engine configuration and will save you from running intake pipes all across the engine bay. You might even be able to keep the Ferrari intake box! To me this seems the easiest place to start, I assume you are looking at roots chargers and not centrifugal chargers (roots chargers deliver more power lower down....). It would require a machined aluminum intake runner going from the engine to the ford intake pattern to get the physical fit. You would still probably need to lower compression, get higher flow fuel injectors, get a programmable ecu, figure out some sort of pulley system....
Hope this helps, and if you do go through with this it will be one hell of a 348!

348's are the hot rod Ferrari - it's infectious reading up on what Bruce, Vince, Goth, Andy, FBB, Group77, No Doubt and all the other guys are doing. Whatever route you take to forced induction, keeping the charge air cool will be an important consideration if you keep the compression ratio stock. Of course, FI is just one way to go - Bruce and Andy went with ITB's, Group77 customized the intake plenum to utilize larger throttle bodies and MAF's and we are looking forward to the projects Vince, Goth and No Doubt have been working on Good luck with your project and keep us updated!

 

A supercharger can be powered mechanically by belt, gear and shaft, or chain-drive from the engine's crankshaft. It can also be driven by a gas turbine powered by the exhaust gases from the engine. I know, I am splitting hairs here, but I recently had this discussion with my son in Mechanical Engineering.

 

Here is mine Supercharged 348.

It has 2 sentrifugal-compressors, made by Cetoni and ZF.

The system is calld BiTurmat.

Max output...544 bhp.....

Wow! Thanks for this Tom. I would also love to hear some details about your car. To echo some other requests:

- Did you do the install?

- Was this a kit, or something you or a local shop designed?

- Ball park cost?

- Reliability problems or any increased maintenance issues?

- And any pictures or videos of it in action? Bet it sounds amazing!

Edit: Found your other thread where you explained that the car was a prototype design, so disregard most of my questions, but I'd still LOVE for a video of it or a sound clip.

 

That Biturmat setup was what I was thinking of. It is driven off the end of the drive shaft (if that's what you would call it) in the center of the clutch housing... I'd look at a centrifugal supercharger or maybe a modified pair of MP62's. You could make an adapter plate for the intake and have the MP62 built into the intake plenum. You would need the clearance on that setup for the drive belt, most likely a 6 rib belt / pulley with an autotensioner. Fast Forward superchargers makes a setup for some 1.8 litre inline 4's. Think two of those.... www.fastforwardsuperchargers.com With 9:1 compression they are getting about 200 RWHP without stressing the drivetrain. If you have double that, you'd be at around 380-400 RWHP (so maybe 460-475 at the crank). Say buh-bye to the others when you go for a 'ride'.

Take a look at http://www.ferrarichat.com/forum/showthread.php?t=65810&page=14 and look at post 278,280 and 284.

About shooting a small movie, well... i live in Norway, so right now it is snow all around....

But i do look forward to the spring, though..

It is 2 different setup on the fan belt to the compressors, so i can charge 0,5 or 0,75 Bar overboost. To be honest, i mainly have
gone with the 0,5 bar version, giving me 400 bhp. But is is just to replace the fanbelt and the wheel on the outging shaft on the
cluch, and i then gets 544 bhp.

But for reliable issues, for the time being, i have gone only with the "slow" version. I do however have plans of rebuilding the
injection system, with a more modern version, like the Electromotive or something. Becouse the system that is on the car right
now is 2 additional electronic ECU`s, and this is pretty old, and therefore perhaps isnt as reliable for the engine in long term.

I dont have the costs of the building of the system, it was already on the car when i bought it. But i do know the developement
costs was huge....

BTW the compressionrate is 8,5-1 and it has a twin Sachs cluch with Zinter racing lamells. But actually the cluch is very drivable.

That is amazing!! What a sleeper!

 

that looks like one fast 348!

 

If you like the look and want the ultimate sleeper, you can supercharge a 308 or even a Mondial, the injected duevolve (1980-1982). Check in with Louis on the 308 boards. I can attest that his car is quick. He is working on a kit with replacement fuel injection.

 

You have a PM

 

I was pointed to this thread, I have the supercharger 'kit' for the 308/328's and even a lysholm setup on the design floor for the 360, much like the above Ford-GT. I'm also at the moment developing a twin supercharger 'kit' for the 348, using to Rotrex Units. I'm set up as the NA dealer for Rotrex units on Ferrari, Lamborghini and Maserati.

I'll be posting pics as the progress gets underway. going for a reliable 450HP but should be able to get 500HP. the Rotrex units are far better at low range than Vortech units I used early on, cost is higher but that's nothing new in this forum of hotrodding. both units will be mounted up front and driven on their own belt.

I figure there is a demand for more power out of the 348's so I decided to design a twin setup for them.
