    I absolutely love my 360, but I really want to buy another Ferrari and I'm really liking the styling and prices of the 308s. My problem is the power, or should I say lack thereof.

    Has anyone turboed or supercharged their 308? If so which is the preferred method for getting more power. Is the car safe to drive at really high speeds once I've added forced induction?

    I've had my 360 to an indicated 189mph and it was very solid in a straight line at that speed. I'm not saying I'd go this fast in a car designed to go 150, but I'm curious how fast people have gone in modified 308s.

    Check out the "208 turbo" a few threads down and prepare to have your mind blown.

    Turbocharging is the most efficient way to go. Call James Patterson at Norwood Performance (site sponsor) here in Dallas. They've done lots of 3X8 turbo applications.

    Good luck

    Turbocharging may be most "efficient", but the ramping up of a supercharger can be less stressful on your engine and trans. Here's what I did, and I'm still loving it going on 5 years later, with no issues: http://www.ferrarichat.com/forum/showthread.php?t=149899

    I've driven it at an indicated 150 mph and the car just hugs harder down to the ground.

    Thanks I read a few pages and so far it's very interesting. Have you taken your car to the strip to see what kind of times you can pull? 300hp in a car that light i'm guessing must be in the mid-high 12 second range.

    No, I've had no interest in drag-type racing... the seat-of-the-pants feel of going from the stock horsepower to now getting 350hp is sufficient for me!! :p

    Why don't you purchase a factory made Turbo? If not, go for a Euro QV. They were the fastest of the 308s.

    There were not 308 model turbos as a factory option. There was the smaller-engined 208 Turbo (euro only, not sold in the USA) and the wonderful 288 GTO. Both look 308-ish, but the 288 GTO would be the car to buy if you've got the $500K+ type of money... very much a 308-on-steroids plus collector value!

    Always interested in high speed stabiity, (even though i very seldon get there :)

    Out on the autobahn I felt the front end 308 GTSi was getting a little light around 125-130.


    I did NOT have the full-sized spare onboard which would have likely made a difference in the feeling.

    sorry for the delayed response. So what do people in the US do then? Look for a 208 that got shipped over here and then modify it? Or just buy a 308 and then add FI? Reason I'm asking all this is because that 308 for sale in the classifieds section really caught my eye and has be thinking.

    328Turbo on this site has a Norwood 328 build, you may be able to ask him for some perspective he's quite knowledgeable. He posted this not too long ago:

    Here is the full thread about that car.
    http://www.ferrarichat.com/forum/showthread.php?t=101045

    I have a Supercharged 308 GTB also, and give a vote to the SC rather that Turbo. There is enought heat back there already for my taste.

    By adding a turbo, my '78 US gtb went from 217 to 290 crank bhp. It was amazing how the throttle response was, even at 100 mph......:):)
    To increase the fun even more I reduced the weight to around 1100kg.

    400hp in a GTS WILL change the way you look at every mid-engined Ferrari. Every single one!!!!

    The've done lots of 308's. Mine is 328 #1 and only! ;) :D :)

    They aint cheap, but.....

    Good work ain't cheap,
    &
    Cheap work ain't good

    What sets Norwood apart is they don't change your Ferrari, they enhance it.
    I know Fchat regulars have read me say that before, but I can't emphasize it enough.

    Norwood built the motor as well. But built it for additional strength to handle the xtra power. Stock compression, cams, etc., etc., so it operates within the same exact powerband --and as Ferrari engineered and intended in ALL situations. So it is more than just fun @ WOT. Numbers are great, but Norwood understands that numbers are certainly not everything.

    Hey Phil, thx for adding the link. Much appreciated, will be adding to it soon.
    Here she is @ the annual show held at CSI. Mostly Hot Rods & Muscle,
    I love American Iron jus as much as European Alloy!!!
    Awesome Pantera, btw.

    328 turbo how much did it cost to get a reliable turbo setup on your car? 5-6k I'm guessing?

    you're missing a zero :p

    well maybe not that much but at the least going to forced induction is going to start around 10k and go up up and awayyyyyyyyy!

    @ smg2, Is she human?

    Mine was done 20 years ago by original owner, John Carmack.
    But back then, when Carmack did his turbo builds, he did it right and paid for the proper development work after the fact. This R&D experience is another factor that sets Norwood apart.
    I know, I know, I'm starting to sound like a commercial!! :D:D:D

    Carmack breaks down costs in this interview. If I remember correctly, it's consistent with the records I have.
