Thanks z-ya

Yes I have been carrying out CFD testing

Thanks. I am pretty confident it will not be a problem.

These use radiussed bellmouths. Best to email sales@customeplenums.com for ordering

There are several reason for this modification:

- remove the factory setup which can become restrictive

- take advantage of a higher flowing manifold but more importantly something that flows more evenly between cylinders

- it is a complete two piece manifold which bolts together and has an o'ring on all mating faces

 

I am also working on an ITB setup for the naturally aspirated guys

Not bad at all actually. Since I have tried to separate them as much as possible to reduce the negative effect the pair ports have. Traditionally all plenums with a throttle moved away from runner one will flow a little less but I do my best to negate this with the straightest path possible. I have found adding a tight radius the plenum toward #1 reduces the flow and then causes turbulence and effecting cylinder #2 aswell, hence the slightest bend possible. I am just finishing this design so I might end up just making it straight once I am done.

Just thought I would share something I have underway for a customer in UAE. Thought it might excite a few people

Inspiring thread.....any chance of getting the links fixed? For some reason the photos arent working for me.

If you go with the 4.5l, go with the later model ones, 94-96, they have a better flowing head with a single port per cylinder compared to the early ones which have the twin ports per head like the japaense ca18. trust, I know, I am the one stuck with a twin port head (I still cant get over it!!!!)
