Good morning Gents I have recently bought another set of Silvertop 20v throttles for a really good price, R850, which included everything just unbolted from the 20v head Throttles, intake, injectors, plenum, rams, injectors, TPS with the plug that goes into it! So the setup is as complete as you could wish for! I now wish to build my own custom setup that will be thoroughly researched so that I achieve the optimal runner length for my application. I have already chatted to Wes briefly about my ideas & would just like to get your guys input as well. I've got the 16v big port intake manifold that I can use to have the flange cut that will bolt to the head & I have the option of either cutting off the flange to which the throttles bolt (20v intake), or tracing it & having another one cut (I rather want a new one  ) I just wanan know where I can go to get the alumimiun cut & where I can find aluminium tubing to make up the runners? All input & views welcome! PS: Please don't tell me to go to Rowland manifold because we do not have a good history & his intakes are far from good IMHO. Regards D-MON

YOu can go to Non Ferous in Soutrivier/Maitland just down the road from Suburban spares. They cut any length for you and have many different sizes. The flange you'd probably have to have cut at aome other place.

Hey Guys
Shot for the replies!
Now just to work out what the optimal runner length should be & then have the correct lengths cut!
@ Nadeem, thanks for the offer, when can I collect? @Boksie, thanks for the advice on where to get the aluminium tubing. What is the guys name that does the aliminium welding that's here in Parow? Number?
How do you guys propose I get the one side of the tubing to be oval (head) & the other will be round already? I know Boksie said in another thread that the 50mm tubing when sqeezed fits nicely on the head side, but that would mean that the throttle side would be roughly 7mm bigger (43mm throttles).
What do you guys recon?
Shot for the help guys!
I'm really amped to get the intake built up!

Well if you going for Dia 50mm then just do what i said but opposite on the flange for the throttles  , go from 43mm to 46.8 to the oval port size, personally i would go this route I am looking for those pics

Some progress... So last night myself & the mad scientist, aka SuperCboy cleaned & hacked up the intake that I got from Nadeem & today Marco's father offered to take the "flange" onto which the throttles bolt to work to be milled flat for us, because after we hacked it up with a grinder, hacksaw & Dremel it wasn't very straight anymore! LOL! Today I'm dropping the big port intake gasket off at Marco's house & he's going to scan it in at work & then have it cut for me for next to nothing!  Connections FTW!  I'm soema going to have a few flanges cut so that I got spare incase someone would be interested in one or just to experiment some more with! & yes, I'll post  when I get the throttle flange back from Marco's dad & also some pics of the tubing that will be used as well as the intake flanges. That's the update for now! 'Til later! D-MON

So yesterday I went to check out the throttle flange at Marco's house & damn it has been neatly milled & ready for the tubing to be welded up! Took some photos with the digital camera & when I got home discovered that the home PC is fooked & my laptop is at my fiance's house  So no photos for now, but know that some nice progress has been made! Marco is currently drawing up the intake flange for me & he's got a connection through a friend to have a few cut for us  I'll try to upload pics as soon as I get the laptop back. Til then, cheers D-MON

Francois, I'm going around to Marco again later. I see your spare sump is laying there.
Must I bring it around to you & then I will bring the throttle flange with as well & then you can take some pics for me & post it up?
What you say?
Let me know!
