ETP 4.8/5.3 vs. Trick Flow 205's 30 rwhp difference!! Vehicle is an M6
Stock LS2 bottom end
HPE S cam
American Racing 1 7/8 Headers
American Racing Midpipes with High flow cats
Fast 90mm
Ported LS2 TB
160* Thermostat
We gained a solid 30 rwhp over the ETP 5.3 230cc heads. Props to Trick Flow for making some very nice heads!

There is a sticky about Vendor vs Vendor threads.. Please go read. I am going to let this post ride, but I am going to watch it. If this gets out of hand I am going to look for individual nutswingers to punish. I dont like Vendor fights and I will ask PSJ to talk to any Vendor who instigates these type of threads...

I wish Chuck would have tested the TFS 225 head that is made for an LS2, maybe you could do that next?
It's amazing that the TFS heads raised the entire torque curve, Congrats on the new found power

As for my car.. I have seen the TFS 225's #'s and there is no dispute on the same flow bench your heads against others flow very well. I admit it is time for other vendors to upgrade, but I cant justify the cost of changing my heads w/out seeing atleast a 50rwhp increase at the same boost levels and I doubt I would see that...

So keep that in mind. Chuck

Dips are usually related to the car, or advance ground into the cam vs. what it actually has in the motor. A cam ground with +4 from Comp won't always have +4 in it due to inaccuracies in grinding... then take into thought inaccuracies in timing chain manufacturing and crank key placement... All these factors effect the outcome of what timing actually is. Thus, sometimes you will have a car that might just have some retard. Only way to know for sure is by hooking up a degree wheel and finding out!

... Interesting results Chuck. those tfs heads are pretty good stuff. We ran our ETP 215 a-b test against our ported ls6 and 5.3 heads, same motor, same dyno same day. We saw almost 44 hp between our 5.3 heads and 215 heads. I will post the dyno sheets as soon as I can figure out how to. This was on a 346 though.
