I am been reading all the prior posts on LS1tech about all of these heads, I have heard bad good and even the ugly at times. I am personally torn between all of these setup.

I am interested in making around 450-475 rwhp out of my 2002 camaro ss A4.

I am confused on which setup will produce the most Reliable power overall. The AFR seems like great heads, But as far as I have read Trickflows seem to flow just a little bit better. The ET Performance have a a lower degree so clearence will not be an issue. If I am incorrect in these statements please feel free to comment. The car is not a daily driver so that wont be an issue but I dont want a crazy insane idle.


The trickflows seem like it will produce what I am looking for. I was interested in there 215cc heads and cam package,
Here is the link

I am curious about if I should go with 205 215 or 225. I am looking at a cam like 228 or possibly 236 but i dont want to flycut the pistons.

ALright all the experts please respond lol Thanks everyone

i just went thru this myself...the TFS and ETs are just better heads than the AFRs. I was debating between the 2 and was slightly leaning towards the ETs. I called several vendors and asked their opinions as well. Basically the TFS and ETs will both have about the same performance, but the ETs will have a bit more PTV clearance (a big point with me since i'm running an MS4), but i doubt that will be as big of an issue with your cam. In the end i went with the Trick Flow 215s because the ETs are at least a 4 week wait. Either way you'll be happy. Stick with a 205 or 215 on stock CI.

I'm going thru the same ordeal. I'm leaning torwards AFR 205 or TFS 215 with a bigger cam and a ported fast intake. right now I have a 228R, LS6 heads and intake.

what are the specs on that 515hp trick flow cam?

Camshaft specs are 228/230 duration, .585 in./.585 in. lift, 112 lobe separation angle
Same as the cam you currently have

damn, I need better heads and intake lol

has to be 515 crank not RWHP no way??

I say AFR 205's with a cam in the range that you are looking for...AFR heads love to make killer power and torque with small to midsized cams. ET's will out flow both tfs and afr heads but i still think AFR wins the battle with a cam in the range that you are looking for...great flow numbers with a small 205 runner like the afr heads equals sick throttle response, power and torque under the curve! It's not always about the most flow...IMO...it's the combo of parts! I am a lil bias though

it will be tough to make 450-475 rwhp on an auto with those cams. you are gonna need a huuuuge friggin cam for sure. if its not a daily driver than fine. but out of those the TRICKFLOWS are definitely making the sickest power right now.. but AFR are right up there for sure!!! i would get ahold of tony mamo and see what he suggests. also you better have a beefed up tranny to be holding that much power man..

Depends on what week it is around here. The "Head of the Week" changes so much I can't keep up with it.....

i really dont see you making that kind of power with any of those heads without a monster cam thru an a4 and even then i dont see it. i made the numbers in my sig thru a 6 spd with a bigger cam 232/234 .595/ .598 112+0. and i had my heads milled to 60cc to optimize the cam. good luck in your quest man let us know how it works out

Thanks a lot everyone, I know I wont get that power to the wheels but if i can get 450 to the wheels it will be all good

I am running a little bit bigger cam than you through an A4 PTC 3600 stalled tranny and my #'s are some what close to yours..

darrensls1

Can you show me some proof of this? Is there a link to some article or thread that backs these numbers up?

I've talked to two shop owners that sell/install/dyno-tune all of the above heads. Both shop owners told me the same thing. ETP 215 and TFS 215 both make about the same power and are both top of the line heads. Both also recommended the ETP 215's as thier personal preference.

actually bu the looks of your sig its a good bit bigger. what did it make?

I think its tough to make 450rwhp in an A4,but I think your on the right track for flipping the coin on really good heads..Although there are some A4 guys here pulling 420 cam only(chris1313 Ithink),and a guy here that goes by "trust" has ls6 heads with a decent size cam(similar to ms3) puts down 440rwhp. I have a friend named Gillbot that puts down 400rwhp cam only in an A4.Now these are all great numbers for an A4 and not everyone is gonna match what they did with there set up with an A4. Every car responds differently. My car is an A4 with stage2.5 5.3 heads ported fast and with a tr224 it put down 417 rwhp. I whent up in cam size here as the car is no longer a DD. The new cam measures 232/238 612/606 111+2 and added pulley. I now put down 435 rwhp.. Was I hoping for more with my mods? Sure I think anyone that mods hope for as much as they can,but I've also seen guys with 6speeds and slightly bigger cams do less..I feel I'm within reason where I should be..I do think though If I had trickflos I would be 450rwhp,but not sure if I wanna spend close to $3000 for that extra 15hp just yet,but if your looking for big DYNO numbers for an A4 do the heads once and spend the money so you wont think "what if my combo had these heads"? I just remembered ther is a member here with the T2 and trickflos and ported fast who put down 430rwhp(unlock).Locked should have put him at 450rwhp+...I hope this info helps you out.. As for me I'm happy with what my car is making.I could have gone with an MS3-4 and flycut and keep my heads to get some better dyno numbers,but I did not want to go real big on the cam. I'm putting money in suspension and getting it ready for the REAL numbers..

plus a dyno number really is irrelevant on a cassis dyno as there is no accurate way to account for drivetrain loss. and diff weather conditions as well as type of dyno can greatly throw the numbers around. i say just get what u want and go whoop some ***. any auto car making that type of power will haul *** if u can keep it on the ground.

If you have excel I can send you the e-mail Brian Tooley sent me after dynoing these heads. This isn't talking to shops. This is a provin dyno sheet!! If you PM me your e-mail address I can forward you the e-mail/
And here is a test of different heads.

And here is a flow chart on the ETP 215s

Again the proof is in the pudding!! Anything else you need?

I showed you mine now show me yours. LOL

Exactly!!! very well put.. I remember with my set up with tr224 cam people who were not familiar with a4 dyno losses would tell "417rwhp is not that much I make more than that"(they are six speeds,and dyno more)yet when we go to a back road and run them its a different story.. I make 435rwhp in an A4,and think thats pretty good numbers for a non dyno queen,and sure If I dyno it at night when its colder,and a few tricks it would DYNO more but I'm just gonna work on planting the power down
