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

Yes 100%! But like I've said already a dozen times, I have no signal but on a mountain side hunting from 12/1-12/7. I asked the wife to text me pics if she can find them. She sent me mine from a week ago. Give her credit! All I have is the very first run and the very last in STD. I want to only show the parts graph and in the proper SAE that again I've already said! Correction doesn't really matter but me only having the 20/20 gain from the start of the day till the end of the day does no one any good!

That's the tuners call to post that. I'm not sure what was done but from days beginning till days end we targeted and achieved pretty much 12.5 the whole time. All I know 100% is the cars timing is WAY down vs what mine and others are. This again doesn't affect all you as the car still made good power but something's up!

If I'd of known better about the owners 08 80,000 miles g37 7at with HFCs id of never picked him as a test car. I wanted a 6mt catless but I'm committed to him now.

Lol well I haven't lied to you. It's not going to be a huge shocker as I've already told everyone where and how the car made power. If someone told me they were African American I wouldn't ask for a pic. I get you all want to see it but I have a pretty photographic memory I'm tying to help with as I'm not home.

Again, run 13 after all tuned stock intake parts-313hp 255tq SAE.
After ported parts with tune run 20- 319hp 260tq SAE after about an hour with swap.
11hp from start to 4500
Zero from 4500-6500
6hp from 6500-7800


Run 2 stock base- 299hp 240tq SAE
Run 20 ported plus tune- 319hp 260tq SAE
20/20 overall

Can't be more exact than that.

I read your whole thread. Getting verifiable results to prove your concept with minimal investment is a tough assignment. But you did it. Thanks for all seeing it through to a usable conclusion.

I compared your 23 degree timing with the datalog on my stock 2013 7AT with ECUtek tune and noticed that my max timing at full throttle is 29 degrees. That timing does not knock on my stock 370 with clean combustion chambers. The reduced 23 degree timing required for your 80k mile test vehicle may be the result of deposits in the combustion chamber causing hot spots and/or raising the compression ratio.

Somewhere in the thread you mentioned verifying flow through the manifolds on a flow bench. That is a great idea. Some cylinders may be receiving more flow than others, running leaner and knocking. If you can adjust the porting to make the flow equal to all cylinders, you may be able to crank in more timing and unlock more power.

That's a good point. If I'd of known more about the testers car I wouldn't have picked him. To much away from what I wanted.

The flow bench testing is done. I'll find out all of the info soon and maybe have Shawn chime in and talk about it.
