    You talk'n like 150'ish ? Cutting the heads is already on the "To do List" and I had planned for 150 but I need to get my fuel issue under control first. If you have a number that works great, please share......

    Dave,
    Your correct Dave, I had a pair of MAD EFI Billet Heads, they were a "little" over 150'ish.......LOL !!!!!! I changed back to stock when I blew the motor last year on a load of bad fuel.




    Grover,
    I run premium 93/94 octane & Aces when on the road. I can't remember the exact cc's for 150 psi compression, Charlie would probably know.......


    DB,
    Did you do the linkage mod yet ??????? Report back when you, would like to have some feed back.

    I didn`t do a modification per say. I simply moved the tpi back against the movement of the throttle blade shaft. I didn`t put my DVA meter on it either. It did make a noticeable differance in the sound on the hose. Sounds "nasty". I`ll report more when i have time to take it to the lake as i`m in the middle of moving right now.

    I'm hoping the"Nasty" your referring to is as in, Sounds Bad A$$....LOL. Sounds like it's seeing more fuel by the audible change in the exhaust.

    Yep, Thats what i ment. I can relate this to installing a larger cam in a hot rod or going to larger jets in a carb. At least at idle anyway. I don`t know what effect it will have at top end or even cruise speed. I didn`t have any problems in those area`s. We`ll see.

    Update to where I'm heading next......IAT Sensor;

    I've placed a micro switch activated by the TPS arm that will be sending a switchable signal to the ECU/PCM. Normal IAT signal during normal running, but a changed ITA signal at WOT. The signal change is in resistance, I'm able to trick the ECM/PCM at WOT that the air temp is 32 degrees, this signals the ECU/PCM to add additional fuel to compensate for the very cold temp signal its getting. Another benefit to this is a little timing bump as well, the additional fuel amounts to a 10% increase. Here's my mock and up as always, its a work in progress situation:

    Dave,

    Thanks for the suggestion, I'm kinda looking at it like this, I'm going to try everything I can without having to lay out some serious cash. As much as the thought of bigger injectors sounds right for WOT, it may really screw up the idle to mid range. It's very obvious that the issue here is lack of fuel since I've now got an abundance of air available. Under my current setup, I'm not that far away from getting it right as I'm running great till the motor hits a wall in the low 80's.

    I got an email from a buddy and he recommended a "Piggy Back" controller system may help. All these ideas are great but there each about $500 a pop with no guarantee of success. What I'm doing is also a great learning experience for me as EFI is still relatively new to me and I'm learning on the fly and besides I'm having fun doing it. Boating days are becoming limited here as winter draws ever closer so I'll continue on my present path and then we'll see what next year has in store.
