    Which springs to use?

    I have decided to go with a TR224 cam with 112 LSA (224/224 .563/.563) I was thinking of getting a TSP 228R cam before and was thinking of getting dual springs but with the 224 cam do you guys think the comp 918s will last quite a while or should I still go with the dual springs. give me your opinions.

    WIth a mild cam like that i'd definately go with the comp 918's, they work with the stock retainers and seats and the beehive design has low operational mass which is good for the valve train and rpm's. The double springs are heavier and require different retainers and seats cause of the larger diameter, unless you are going over .600 lift i'd stay with the 918's, they are good springs for your application and just happen to be very affordable. I was gonna get the comp 918's with a milder cam to save money but im going straight for the ms4 cam which requires double springs and i'm goin with the prc kit.

    The 918 will be fine as long as the installed height is correct. If that is right you should have NO issue. Just make sure that lifter pre load is correct during install.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    Some people say that dual springs increase hp by not activating knock sensors. Is that true?

    Actually i believe it was some of the earlier dual springs that were triggering the false spark knock and timing retard cause of the harmonics of the dual spring, however this is corrected with the newer versions, correct me if im wrong anyone!
