Im just trying to see if anyone has used Trick Flow Heads with custom cam on an LS3 and what type of gains where seen?

I have heard great things about the trick flow heads... yet cant find many personal reviews of people who actually run them,

I'm about to pull the trigger for my 2011 GS Manual yet want the biggest bang for the buck and just have not seen the reviews needed to feel confident.

I was thinking about having the TF heads ported as well...

For the price, I don't feel 500ish HP is worth the price of admission. I would like to see 575+ RWHP... I may go boost however I have always been a fan of the predictable NA power curves.

Thanks ahead of time.

I guess that answers my questions... LOL

SPEED SAFE, NICK

LOL. I didnt reply because I have never done it but there was a car at the last MIR rental that had TFS heads and a G6x3 cam with a ported fast 102. I think I saw it run 132MPH N/A.

Talk to Tony Mamo. He has done this combo and can show you some results.

Did not use trick flow, but they r very good heads. I used GMPP heads & then milled .020
half the price. vengeance kaotic custom grind, LG 1 7/8 with high flow cat. corsa cai, B&B fusion (2011 grand sport manual trans ) 533.8 rwhp 473.5 torque. Scotty Dickens have the heads 88958758 PRC301 1400.00 Shipped

Flow #s r very good, this heads r CNC ported, hollow stem valves. 623 LIFT flow 355 CFM (intake)

jleews6

Good numbers. What intake are you running? Any track numbers?

carpayne

stock intake, only #s I have 147.5 mph wannagofast 1/2 mile, hoping to pick up 4 to 6 mph. going to Ocala fl in jan to see what I RUN

how'd it go?

I have and very happy with the results 129/130 mph consistent 10.4/10.5 in the quarter in street trim still with factory intake and throttle body llsr E85.

These cat below could not catch it...

Bigwebb

very cool. What head cam setup are you running again"?

xBoostx

I'm running Trick Flow 255 with low lash solid roller cam e85 cam specs a little wild but is just awesome on the street great low end torque.

Cam specs 236 242 677 677 113 +3

How long have you been running that setup? How long do expect your springs & etc to hold up?

xBoostx

About 1.5 years on the set up around 5k miles using same original Trick Flow springs no sign of weakness shift points @ 7.2 on the third set of drag radials.

Navy Blue 210

What Rockers & Lifters are you using, compression ratio?
HR equivalent ~ 230/236 I would call that Schmedium compared to
some of the cams I see specced for LS3s.

My LLSR is 243/249 115 +3 (17.5* overlap)
real challenge to tune drivability in a 99 C5 PCM,
especially with mid-length runners & a lighter clutch.

Do you have a Dyno Graph?

xBoostx

I'm using a few good supporting parts to eliminate weakness and service so T&D machine rockers.

Using these lifters...

I milled the heads .150 thousands chambers @ 45 cc so 14. to 1 remember with E85 stock short block & pistons except for fly cutting.

The ghaph below is quite likely to start a controversy but is what I got from the Dynocom.

Bigwebb

did you do any additional port work to the heads to offset that substantial mill?

xBoostx

No additional port work IMO is totally unnecessary these heads are very flow generous as they come enough for even a very healthy ls7 in fact.

Only for a four hundred plus cubes and a max effort will I bother with any additional port work on these heads.

Bigwebb

That about the reduced combustion chamber volume from milling?
