    Finally have pictures to post.

    This system uses TWM throttles and a TEC2 engine managment system. Otherwise the engine is stock. Throttle responce is superb and the sound, ......... words can not explain. On the dyno last week we had 252 HP to the wheels which calculates to about 305 engine HP. More upgrades to follow on my quest for 400 normaly aspirated HP.

    Wraith: That is AWESOME! Outstanding implementation!! Also notice you moved the oil filter. How easy/difficult/long has all this been for you to do? Cost? Can you post the dyno sheet? Would like to see the rwhp and rwtq curves. Thanks!!!

    My first thought when I read "TBI project" was putting a Chevy truck intake on your car...... :O

    Magnificent!
    A very well done installation.
    What's the plan for airboxes, cleaners and ducting?

    Great job!

    Looks really nice and 252 HP at the wheels is even better!!! I bet it sounds great. What other mods are you thinking about?

    Keep up the good work!!

    Again - terrific installation. Would also love to see what A/F ratios at tip in and top end you fornd best. Also - did you find about 33degrees @WOT about enough advance?

    Wow!

    Holy crap, 252 at the wheels? Did you get all that with just the EFI? What about the pistons and cams? Are they stock?

    Now inquiring minds have to ask: How much did the conversion cost?

    I'd love to view this car in person and to have a chat with you about the details.

    Will you and the car be at the Wendy's Italian car show in Dublin on Labor Day, or else the Ferrari Club meeting in New Albany towards the end of September?

    Cheers - DM / Also in the Columbus area

    Looks great and the dyno tells it all. 2 minor questions - 1. did you check to see if the fuel guage is restricting flow? I did the same setup and when I sighted the fittings, I found the stem of the guage protruded quite far into the fitting. 2. How are you addressing the valve cover breathers? From the pictures, I could not tell if you blocked off the breathers, or if you had some special fittings that let them breath but blocked out the oil.

    I am planning on in line cone filters but have not worked it out yet. Pictures will be posted soon showing airboxes. When the boxes arrived they were not the dimentions advertised. (They were 2" to tall) I could have shortened them but I have been thinking of a way to impliment a lexan cover anyway. after stressing for days I decided to cut the lid!!!

    I tapped them to accept 10AN fittings and installed the original spiral screens in the fittings, Then connected them as they were to the crankcase drain.

    Yes, I think it is 34 now but I am still experimenting. The biggest problem I am having is getting the tps settings correct. It has a flat spot just off idle on accel. When I correct it throttle input at cruising is adversly affected. Engine mapping is probably a never ending process.

    Very impressive.
    Just as a comparison point, my stock 3.2 with Webers put out 243 at the rear wheels but gave about 204 ft-lbs of torque. I'd attribute my greater low-end torque to my displacement and your higher end hp to more open throttle bodies flowing better at speed.

    I understand about the plight with air cleaners after trying many options on mine - I think you will be very happy with the twin high volume plenums although you had to cut the deck. Actually, Paul Sloan with his radical 48 IDA/F Weber 308qv had to do the same thing with the back deck you did to have clearence. For my rather more conservative set up I used a stock 308 airbox or the now installed custom aluminum twin plenums with K&N ram cones in the side vent still using the stock bonnet.

    Good luck - it's beautiful. I'm very interested in following your A/F curve adjustment.

    best

    Wow.... nice dyno numbers!! Have you done any other mods or just the TBI?

    Interesting what you did to the engine cover. Looks pretty cool :)
