Hey guys...
Long story short I have a Built Forged 346ci LS1 in my Car...
Has the following Mods:
Fast 102 LSXR
PTM 102mm TB
PRC Stage 2.5 5.3 Heads
Comp G5X3 Cam 234/244 .610/.609 112 LSA
25% UD Pulley
12lb Flywheel
Ford 8.8 w/ 3.73's through a T56
Sanderson Block Hugger 1.5" Primaries (TINYYY HEADERS!!!!) with 2.5" Collector running to 2.5" Downpipes then a 2.5" X-Pipe Dumped.

Anyway, The car Ended up with 391rwhp Peak & 365rwtq.



I since then decided to go Turbo, so we pulled the FAST 102LSXR & the G5X3 Cam...

We Installed a STOCK LS6 Intake, and a Turbo Cam 227/223 .614/.610 on a 115LSA and re-dynoed the car for ***** and giggles before we tore it apart...
Mind you we DID NOT tune the car... just did a quick pull UNTUNED and ended up with a peak of 400rwhp & 370+rwtq on a fatter powerband!
Sorry no dyno graphs to scan :-(

Just kind of shows you that the wrong combination of parts can hurt more than help...


Sorry, just bored a little thats all :-p

I dont get it. Get a full tune and report back. Like comparing apples to grapefruits. I think I read it wrong. Its NA but you are going turbo? Then I get it lol

i guess the smaller cam produces more power?match that g5x3 cam with afrs or trickflows then see what you get!

thats the name of the game getting parts to perform with other parts,i see your comparison tho.

More like match it to a good set of headers. Your right though, it's all about combination .

wrong headers for 1 on a na car

the headers were the limiting factor obviously

Sorry maybe I wasn't clear enough...

The engine is in a miata so header options are non-existent.
So whats in it is whats staying in it.

I installed the Turbo cam so that we can tear the car down and install all of the turbo components... but BEFORE we tore the car down we decided to do a ***** and giggles dyno run with the Turbo cam in an N/A Car...
We pretty much were extremely surprised with the numbers!!!!

So in conclusion... that HUGE Intake and that HUGE Cam did jack squat for the car!!!!

I'd almost agree with you but the same headers made 510rwhp on the 100 shot... which proves they CAN flow at minimum 510rwhp... maybe not efficiently but they did make the power.
Make sense?

I'm sure if I magically installed a 1 7/8th longtube it would gain 40-60rwhp.

Thats a horrible comparison. Throw a factory LS1 intake manifold on it and you would have the same thing.

Or throw a 100mm turbo on it now and run it at the track, then throw a 70mm and run it. You cant compare things based on **** poor combos. Knowing you could only run 1.5" headers you shouldnt have even thought about running the combo you did.

I agree with you... I guess live and learn?

On the flip side... At least they are great turbo headers!
Lol.. we chopped off the 2.5" 3 bolt flanges and welded up some 2.5" V-Band Flanges...

Of course you got shitty numbers through a g5x3 with those headers. That cam has so much overlap i wouldn't be surprised if the backpressure from the headers caused enough reversion to spit fuel backwards out the throttle body.

Common sense.

So because he made more power by changing the parts out and didn't retune wasn't an improvement even though he made more power?

Hypocrites!!

Tough way to learn when all the info available out there would have confirmed the first combo wasnt going to perform. Hope your next combo is researched a little more....good luck.

And yes, bigger is always better if done correctly
