Ah right. Doesn't look like it on the pic so you've done a tidy job of that.
That's not my one, just the picture I used to plan my design from

How do the runner pitches match up with the f4r flange. You'll need a custom fuel rail also then.
What power lever is this inet rated to?

I'm in the process of building one of these, well similar in concept
I thought about using the pulsar manifold too. It makes a good starting point with a lot of the hard word done.

To convert a 172/182 to the 197 is a mission mate. I've done it and it's not worth the effort. That's one of the reasons I went to a 197 head/inlet combo. Plus, the 197 head is far superior to the 172/182 one.

Not on FB. What they saying??

Mega detailed stuff. Makes for a good read I've tried to copy the link
The Honda forums are really good for this stuff as they are light years ahead of us in the all motor side of things

Link would be good. Love reading up on stuff like that.
Really??????
Can I have the measurements I personally think if they are going to design one then do not try and rip someone one off and use there info.
Steven I think you should reproduce yours as it is i think there is lots of money to be made if £700 is going to be the going rate.
Simple question, I'm the middle man here and it would of saved me measuring it up myself.
They are going to be designing the inlet from scratch. Measurements were only in regards to clearance from the face of the head around the engine bay so they have an idea of the dimensions they will be working with.
seems like there will be a lot of different options
will be interesting to see some afr logs on some of these

I'm doing the same thing only on 197.
Running some simulations in Solidworks at the moment.
Hopefully, will have the first prototype carbon inlet for my 197 in the next month.
Will have dyno tests before/after the inlet.
It will be bolt on the lower inlet manifold.

Surely that's going to be a very short runner length though?
Yes it will but take into the consideration the length of the lower part of the plenum...and I'll have some "spacers" made extra so I can "play" with the lengths of the runners and see the results on the dyno/street.

I think you'll lose a fair chunk of torque mate with such short runners. Do you have any images you can post? It may help me understand your design. Don't worry I'm not out to rip it off! I'm very much sticking with the 197 inlet on mine.
Will post it all together with the dyno results when it's made and tested out properly.

45deg is not uncommon and most aftermarket manifolds will be that. It should not be more than that and obviously the lower this angle the better. Itb's will have a 45deg injector angle but further away from the head. V8 dragsters in the US commonly use and injector angle of 45deg.
What's so outrageous about this design?
What angle is your injectors Scott? What did scoff say about the injector position and angle for mapping?
Clio T 314hp c43 AMG
Unsure as focrs made it, I think he helped make yours to? We discussed it a while back In Your build thread, you would need to ask him as I'm unsure.
The problem was that 480cc Megan injectors were "wetwalling" so there was no way I could move up to 630cc as planned.

Hi Scott, 630cc were not the problem, more that we didn't need them to be so large. The steep angle and proximity to cylinder head in your case made it difficult to tune throttle transients. It needed a lot of tip-in enrich, a large but short burst to compensate for the port wetting. An OEM calibrater would find it wholey unacceptable but with a standalone one off we can live with it
R5GTT, 2L turbo
Maybe its my ageing mind but the injectors looked steeper in the flesh. It could be that the injector sockets are too long and are obscuring some of the spray pattern. There's a few possible causes. Its difficult to know without taking it apart and having a good old look. None of which will impact on power really. With a modern cylinder head you can almost chuck the fuel in with a hose pipe and get away with it.

Warning! Old thread resurrection hehe.
Anyone who were building them manifolds finished any of them?
