Any reason you are changing Jay? Anyone else have TFS forced induction #'s to back up a change?

If you are interested in more details, graph etc here is the title of a post AFR made in this section a month ago, it shows dyno graph
"Boosted 346 w/ AFR 225 cracks 800 RWHP!". I do not know how to give you the link directly but a search of "Boosted 346 w/ AFR 225 cracks 800 RWHP!" gets you there

AFR- Low price Thick deck proven performer
Allpro- ok Price super thick-semi dry deck (6 bolt available)
ETP- High Price .900 deck (6 bolt available)
PIck your poison, so far they have all been in the 7's. AFR's powered Casper into the 6's years ago.

AFR's are definitely not low priced. A set of CNC'd LS6 heads for $1,000 might be considered low price, but certainly not a set of $2,500 after-market heads.
How much extra power do people expect going from AFR's to TFS heads?

I am beginning to think people base their decisions on whatever the latest fad is...

That is entirely possible,however,I suspect it is due in part to writeups and articles showing big numbers with XYZ 265 heads. So most people assume they too will get those results. I wish Phil would chime in as I think he has experimented a little with some differnet heads for FI. I would like to hear his opinion as well.I will volunteer my time and car for some back to back tests,that would be interesting to see.

Do you happen to have or would you be willing to post or PM before and after with your setup ? Any other changes or heads only ?
