    I tried the second ones late last season, no changes either way. Worked fine. I will probably stay w/ those.

    This was w/ ~23psi!

    Chuck...real quick..so not to steal the thread.

    How do you like that TFS -R intake. I've been kicking the idea of this intake on my 351 and 23 psi out of a NOVI 2000 or YSi. What do you think? I don't really think I want or can fit the BOX-R...plus I see a decent amount of time on the street.

    Old Downs & GT-40 w/ port & polish gone. So I am moving from this setup!

    Thanks
