Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

I hear there's someone in here without the ability to back up their claims?

Amateurs.

Or was it clams?

Give this guy a chance to explain what he has going on with his porting setup.Nobody gave me more of a hard time about my extruded lower intake than this guy but he deserves some time to post his results. We all have jobs and other life stuff going on.He'll post them when he gets time.But from what i saw his numbers look great with the porting job.My hat goes off to you for thinking outside the box.

exsanity

I'm giving him ample time to reply. I just want scientific method he used to generate these numbers. As the great Han Solo once said a long, long time ago..

Not really sure why everyone is so negative regarding this test, you could put the best throttles and manifold in the world on that car and the gains would be small while still running factory cats.
If the exhaust is restricted the gains in the manifolds will not be seen.
Really the only proper test is on a car with proper headers, no cats and intakes that are larger than the throttles.

I dont think the exhaust is the hold up im running the most improper headers according to this forum(Stillen). And i have Z1 HFCs.337whp 267tq. not bad no idle issues and the throttle response is incredilble.

These gains seem right on to me. The z1 manifold picked up about 11 hp peak over the m370. The m370 loses about 7 hp over the stock manifold on a full bolt on car. So lets say z1 picks up 4 over stock, and syn picked up 6 on a hfc car, which is great considering the z1 car had headers. Its just a ported intake, don't expect miracles , if you want the last little bit out of these cars this is a no brained. People spend more for an m370 to loose peak power. Oh I forgot m370 makes more under the curve, which doesn't matter after 1st gear.

As I said in my reply you quoted, we believe we got good air in hence the 11hp increase from 2-4500 but the cats maybe killing us getting that air back out. We are not sure. Like I said also we will test this next week when the owner comes back with motordyne helmholtz test pipes and we reinstall his oem stuff and we do it all again. Also his 20/20 was his 1st or 2nd run vs his last. That means parts plus tune.

I'm referring to the title of this thread. I'd thought by now that'd be obvious. Apparently not. So we are talking about ported upper and lower manifolds and CNC throttle bodies.

Yes we do have a base line. Trying to get the wife to text it to me but again I'm on the side of a mountain hunting so its hard with no signal. The sheet I will post with no parts plus tune, then parts with retune will be just that. There is no dyno with just parts because the customers car started to knock. His final tune is actually less timing then it should be and what the stock parts plus tune had! This automatic car was giving us much headache.

This is FP at his greatest never knowing how to read! Way to post the 400hp pack in a thread not taking about the 400hp pack! Way to go champ!

Now use your useless skill had find a dyno that's relative to the thread. Show me Z1's before and after ABOUT THE THREAD TOPIC ONLY!! that's right, you won't find one like I said. Z1 only shows their ported mani vs a m370. Zero proof of a ported vs unported because like I've said!! I bet it's only good for 1-2hp! We believe we can get 10/10 across the board but only with all 3 parts!! Exactly what I've said and I expect from these items.

How does power under the curve only matter in first gear?

I gave you no hard time except I said $600 was to much for the gain on just your lower. I've just proved this. For a little over $800 for a ported upper, lower and CNC TB's from me I do believe that's worth it for the gains. Some may disagree but that's fine. All that have spent $1600 on a CBE I believe that's a huge waste. If people think $800 is a waste on 4 ported parts then that's their opinion too and it's fine.
