Who knows if the tune for the 5.3 heads was even optimal. They may have gained 10-15 on the stock castings with a better tune. Too many variables to state that just the heads gave that amount of gain. I do not believe it.

Thanks for reinterating what I had already said.

Ask yourself this. If you were shopping for heads on a stock LS1 motor and you glanced at ETP's lineup, which one would you consider?

My answer is the ETP 215's. So if I were comparing ETP to Trick Flow then I want to compare ETP 215's to Trick Flow 215's. If both heads were tested on the same car with a typical street cam (F13 lets say) then I would be most interested to see who comes out on top and by how much. That would be a fair and real world "apples to apples" comparison.

But this comparison does nothing to satisfy my curiousity and it certainly doesn't prove to me that Trick Flow > ETP.

If nothing else, this proves that the TFS are capable of making 480+ rwhp on a variety of different dynos from a variety of different shops.

I dont think this thread was started to be an "End all" comparison by any means.. Chuck, correct me if I am wrong...

I think the post speaks for itself. Customer came in with ET 5.3s and left with TFS heads making X amount more power.... Shops post results like that all the time. I see no harm in this comparison and I am more than happy for the guy making 480s with TFS heads... I have yet to see a TFS combo done properly lay down less that 465rwhp with AWESOME street manners

For all of the guys who think the comparison is "useless" start sending your local speed shop some financial support to do the back to back testing you want to see done... I personally dont know many people who will buy two sets of heads just for the sake of comparison ....

BTW, we sell TEA/TFS and ET heads... So Im not biased either way

Post speaks nothing but his last results. Was it tuned right the first time, old set ET heads? Maybe HPE got the tune right this time with a set of good flowing heads? I don`t disagree there heads flow great. Just not a honest head to head test. Would have like to at least see HPE to have played with the old set-up and got numbers, then swapped and retuned. Would have helped alittle and would have only cost dyno and tune time for HPE. Great number though!

God he just posted a before/after dyno so there is more info out there and all you guys are doing is giving him ****.

I think this thread would of went over better if he had just compared them to ported stock castings and left ET's name out of it since he wasn't comparing both companys top of the line products.I think this just helps confirms what most people had already figured,that TFS 215 heads are better than ported stock castings as are ET 215 heads.Neither company would waste their time making theses heads if they didn't think they offer more than the stock casting.

etp 5.3l heads are what you get in the hpe stg 3 h/c package.... i'm sure they did the work the first time, as well as this time. same shop, same tuner, different heads... i don't see any issue with this comparison.

i think this is a great post for the simple fact that i myself have seriously been considering going to a budget head such as the prc ls6's and seeing comparisons like this really make u think twice and realize just how much more could be had.

Carey @ ETP posted his results in this thread ... Good info.

Out of the box ETP heads from about 5 months ago. Original dyno run also done about 5 months ago, when the heads were brand new.

WE installed the ETP 5.3's on his car several months ago. I did the tune on them after the install. Same as after the Trick Flow install. I have never seen ETP 5.3's make over 465 rwhp in an f-body, this was a Goat. Both tunes were optimized for each combination at the time doing the work.

Thanks Chuck for the clarification. I assumed that if you were doing it the comparison would be fair.

I suspect there would be mimimal difference between the Trick Flow 215 13.5* heads and the ETP 215 11* heads.

As was mentioned several times already, all this thread shows is aftermarket castings are better than the ported stock castings.

I have seen the TFS 215 tested back to back to a ET 215, but if I post the results the mods pull it.....

If you would like to know feel free to PM.
