How do the runner pitches match up with the f4r flange. You'll need a custom fuel rail also then.It's a Honda one I've bought a f4r flange and going to chop and weld it on. Injector bosses welded into the runners or just use the other 4 that are underneath. It's got flushed trumpets
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.Given the R3 Maxi Evo makes 250 on the standard inlet manifold, is it not possible to swap to the mk3 manifold rather than fully fabricating from scratch? If it requires some work to fit is it not likely to be at least less work/easier?
Really??????I don't mean to be cheeky but I don't suppose you have any of your original measurements do you?
I won't be designing or building the inlet, but any extra input for the guys at Zisco would be a bonus. They're the chaps with the software and expertise to pull this off I'm just the middle man
Thanks a lot, Craig
Simple question, I'm the middle man here and it would of saved me measuring it up myself.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.
I'm doing the same thing only on 197.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.
Surely that's going to be a very short runner length though?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.
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.Surely that's going to be a very short runner length though?
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!

Catcams 5504402Ok mate. What's the rest of the engine spec?
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 wrong with your injector angle? It shold be arround 30deg comp. to runners. This is one of the worst designs I have seen so far... Outrageous!
What angle is your injectors Scott? What did scoff say about the injector position and angle for mapping?
