    He could be wrong but a friend told me to stay away from the Riva 50s.

    thought you were getting 1100s....

    750cc will max out at 400hp and about 250hp on e85

    50lbs are all done about 285 hp

    42lb @58 psi and 100% DC is 245HP with pure gas
    and your asking for trouble any time you try to run a injector in the high 90% DC
    IMO 215 safe HP

    Both are the same Delphi injectors but Riva's are supposedly flow matched. These injectors will lock up under higher fuel pressures causing a lean condition in one if not all three cylinders. If one cylinder tends to lock you will lean that cylinder, while trying to compensate for the high AFR (your reading all three cylinders) you will want to add more FP thus further compounding the problem and likely burning a piston. I seem to remember these locking at 62-63ish lbs. Stay below that and you can run them all day every day without issue.

    i will get the 1000's for sure just that these look like the 50s i recently purchased and if they are the same some one could score at a better price not sure if they are any good i haven't had any issues with the 50s i used.
