@Van B @mb911 Your pressure was too much. I caved and ordered a set of Furik stuff. I'm such a conformist... On another important front, I have appointments this coming week with two different tuners to talk ECU selection. One that's in contention is the new ECU Master Pro series. The big add is they now support dual drive-by-wire throttle bodies - a requirement for the 360. I've been really happy with their PMU and ECU Master seem to be making inroads with the motorsport crowd as a budget-friendly option to the MoTec and Haltec product lines. We shall see. Did you happen to see what Furicks main business is? The TIG products are a sideline |

Conformist lol… that joke was so dry I need to go get a drink!
You’ll love it, I promise. The #12 has become my go to. I can do 25 cfh on the flow in just about every situation, up to 1.5x cup diameter stick out. Watched your video before getting back on the sway bar configuration struggle bus this afternoon. Your headers remind me of an X-29! |

2nd side all welded, along with a rear view.
This was quite the learning experience. My TIG skills improved an order of magnitude - maybe more. Once I get the Furik stuff, I'm sure to be the next Instagram porn welder/influencer, right @Van B ? (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/lol-2.gif) Now to get the drive train back in the chassis and work out the rest of the exhaust. Plans include leveraging the Ferrari muffler by-pass and trigger it via the ECU as well as having a "Sport Mode" button, just for Cars & Coffee!

Haha! No, you have to practice ridiculously close up photos at a 30 degree angle using 1/3 framing and portrait mode. And you can’t take pictures of actual parts with a purpose. Only pointless practice objects with no use in the real world.
So, basically, you can’t work on the Porarri anymore. |

Back to the project at hand, you nailed it on the header design. I understand the desire to improve execution, but I don’t think a better lay out is possible.
The symmetry and common design themes will take this to a whole new level! |

On another important front, I have appointments this coming week with two different tuners to talk ECU selection. One that's in contention is the new ECU Master Pro series. The big add is they now support dual drive-by-wire throttle bodies - a requirement for the 360. I've been really happy with their PMU and ECU Master seem to be making inroads with the motorsport crowd as a budget-friendly option to the MoTec and Haltec product lines. We shall see. Fun! Not sure who is out there, or the Ferrari presence, but I'd also recommend looking into if anyone locally will tune a Syvecs S8 or LR F88. They used to be slightly more cost effective than the MoTeC options, but I haven't bought one in a few years. The ECU Master stuff is getting nicer, though it's still a bit out of the capability range of offerings from MoTeC/Syvecs/Haltec (the newer Nexus at least-brainchild of Andy Wyatt who is awesome). Perhaps not a big deal, but the big difference from the others to ECU Master is the lack of FPGA for engine speed tracking. Some people think that is really important for complex DBW, but who knows... (IMG:style_emoticons/default/beerchug.gif) I think it's mostly down to the tuner anyways. (IMG:style_emoticons/default/smile.gif) Header looks awesome!! Really fantastic work! With the smoothed welds it looks like you had someone custom bend the start of the primaries.

Drive train back in with both headers. They are pretty well hidden so they look better in real life where you can move around to get a look at them. But everything fits. On to working out the rest of the exhaust.

Should have made the headers come up and out like an old drag boat so everyone could see them. haha

All this work on the exhaust had me ignoring the other end of the system. So... I found a damaged 360 intake manifold at a sorta local exotic car recycler.
Having a spare set up enables me to try out some modifications I'm considering while preserving a standard intake. If my ideas work, I can always sell the factory one. Attached image(s) |

First step was to anneal the area to soften the aluminum ahead of moving the dented area back into position. That's why the burned look.
Then it was: damage removed, cracks ground out, patch piece made and initial metal finishing underway. That area of weld yet to be addressed was a low spot that revealed itself during the filing process. The lip at the mounting surface will be the trickiest. The damaged area is at the front of the engine so not the most visible area, but we'll see just how invisible the repair can be. It'll be wrinkle finished so that'll help hide any minor flaws.

Please, please include pictures of the interior of the plenum, both the air horns and the top section.
I've wanted to see the insides of that intake set up from the start. I'm especially interested in the cross tubes near the air horns. Thanks Rick |

I'm especially interested in the cross tubes near the air horns. Thanks Rick @technicalninja Rick - See post #106, earlier in this thread: http://www.914world.com/bbs2/index.php?sho...9314&st=100 Essentially, it's a set up that doubles the length of the intake runners to improve low RPM torque. The intake runner butterflies open at >45% throttle and >5500 RPM. There's a butterfly valve between the plenum chambers that opens at what I suspect is the same time. I've been trying to educate myself on intake manifold theory and must say, this one is quite a marvel. 110 hp/liter is pretty impressive. I'll get a pic of the inside of the upper plenum in a future post. |

Thank you! I haven't taken the time to go all the way through this thread and probably should have.
Variable intake length started in the late 80s and the "normal" path is long narrow tract below 60% of the RPM range and big, short tracts above that point. Making the runners super long was an April Fool's joke for Holley but... https://www.youtube.com/watch?v=y9IERetMoL4 It made a LS based engine into a diesel. It was done as a joke but running it on a dyno provided really good data. Those "Rat Fink" cartoons actually had a basis in reality. I'd love to know the length of and diameter at both ends of the high-speed sections. That Ferrari has far more taper than most and I'd love those numbers if possible. It's a bit creepy but... I want to fondle your intake (IMG:style_emoticons/default/shades.gif) |

The throttle bodies need to be tipped down to get them to end up under the height of the trunk lid. First step is to slice off the mounting flanges. This in prep for welding on a bit of curved tube. The flanges will then be welded to the end of the newly added tubes.

Shuffling cars so I can work on the LS build while I wait for some parts for the Ferrari car.
This is the first time it's been outside since the drive train swap. Note the intake turn-downs won't be that severe - they'll be maybe about 45 degrees with just a bit of straight before the throttle bodies. But it'll look mostly like this. It'll sit a bit lower, too. Attached thumbnail(s) |
