Looks good I will be going similar design for the 240

shows how much you've read on Colin's project, as if I recall correctly Colin's front engine produced 430+ bhp and that was attained with a home made intake manifold similar to Robs.......also the rover manifold you mention was superseded by the twin plenum version for the performance 3.5L Vitesse model, which I my mind means the single one didn't produce the power they were looking for.

Inlet to the plenum is not really an issue on forced induction engines, the idea being that the pressure being higher than atmospheric should not have an effect on intake pressure as it would on a N/A engine with negative intake pressure.
Saying that, the plenum should be of a size to accomodate intake fluctuations of pressure. The runners are also very important. The size and length of the runners will affect power through the range, shorter giving more top end power I believe.

Despite all the knowledge here...Lol...it is strange why Hussein in the LINK has gone back to his N/A ME7 manifold ???

The Twin Plenum as on the SD1 Vitesse was nothing to do with the Single Plenum on the ordinary SD1 3500.
As you should know the 3500 came out detuned as it was a very fast motor and it had twin SU carbs @160bhp with a gigantic airfilter box on top of the "V"...V8 together with Watts Linkage rear suspension so it did handle.
To keep up with technology of the time about 1983 the injection version came out which happened to have the Single Plenum end of story...
Then the Vitesse came out which was the performance model @190bhp and a top speed of 137mph, it was at that time the fastest production hatchback...how long for i don`t know. But this was Twin Plenum...
Not getting enough power had nothing to do with it!
.................................................. ........
I believe i read to page 71 so i will have to get back tomorrow and read the rest.........very interesting read.

I don't want to derail Robs thread any more, but again, you have many facts wrong, Vitess was the first sd1 with injection, then later on they introduced the VP efi with the same engine, then at the very end of the production run, the twin plenum was introduced on the vitess for homologation reasons for racing.

Going to go back to the top of the thread to look at the nice shiny engine bits...all this talk of rovers is making me feel queasy......
I don`t really like it when you knock members posts all the time just to make your self look above others!
Apart from your spelling...if you go back to the "Wiki" page where you read your information from ,if you look a few paragraphs before that you will find that you are the one with factual errors.....everything i said was correct but of course you yourself are only talking European Rover , i am talking complete SD1 model!....hence the single plenum model.

American emissions regulations necessitated other differences including replacement of the carburettors with Lucas' L-Jetronic fuel injection system and the fitting of dual catalytic converters, a modified exhaust manifold and de-smogging equipment. The engine's compression ratio was modified to 8.13:1. Publicity material claimed it was capable of reaching 148 hp (SAE) at 5100 rpm[12] but the car as sold actually peaked at 133 hp (at 5000 rpm).[13][14] A desmogged carburetted engine had already been on sale in Australia since August 1978, with 102 kW (137 hp). Australia received a version of the fuel injected federalized engine with 106 kW (142 hp) beginning with the 1981 model year.[15]
I am sorry about any queasiness....Lol... but facts are facts and have to be brought up!

Can a moderator please remove the posts that are not keeping with the thread about my plenum chamber.
Thankyou.

Hi,
That plenum is great, a plenum needs to be as big as, or more than engine capacity to be efficient!
As for the runners, I cant really help. Modifying engines is trial and error and I doff my cap to you guys that are prepared to do what you do!
I have seen variable geometry turbo's and constantly variable inlet tracts making a big difference in engine builds for power gains through the range.
Hopefully you have the right combination for what you want to achieve. either way, a nice bit of engineering, and will keep an eye on this with interest.
Cheers
Paul
I have something similar for my 940

Looks very nice Carl, but will it ever get used?
Another one of inside plenum
