Who's Got The Biggest Bulge????
after having a word with a 'freind' who 'does' sierras i have decided i may well be keeping the 2.0i pinto with its injection
gear as is...
Before you all start shouting "IT'LL BE TOO DAMN TALL" i am aware of this, so i'm looking for a glassfibre bonnet that has a
bulge bigg enough to fit. (probably to fit an MK Indy, but as i havent bought the chassis yet, this could all change)
or do y'all know of anyone who sells metal ones that could be 'adapted' to fit???
Please feel free in advance to: correct, update, ridicule or laugh and point at any comments made by myself in this post....

If i am right, then isnt the plenum chamber much higher than the rocker box and way off to one side? so your bulge would either have to be the full
width of the bonnet or stuck over towards the passenger side, just take a look at the Dax...

the trick is to shortern the plenum and lay it at 45 degrees so it goes under the bonnet with no bulges,see robin hood site somewhere,been there got
the shirt etc
who cares who wins
pass the pork pies

Wadders, is that bonnet made so you can fit the 2.0i plenum under there??????
also i know the 'big shiny thing where the carb should be' is called a plenum, but what does a plenum do???

Very basicaly, a plenum chamber is an air box.
I did say very basicaly..

the plegnum is supposed to act as an air resovoir to smooth the flow to the intake ducts. The volume and the length of the inlet tracts is supposed to
have an effect on engine power / torque.
The V12 xj-s I had could be fitted with modified plegnums that supposedly added 13% torque just by tuning the intake lengths.

Err not quite, it covers the air filter and carb tops of a ZX9R motor, which poke through the bonnet about 2 inches.

carcentric, tried contacting that link, his answer was cut a standard bonnet and graft a bulge or bonnet scoop on myself.
not exactly the answer i was expecting from someone who calims to be able to make anything for a car in any material...
thanks for the tip tho,
when i get that far, i have a feeling i'll be cutting the bonnet myself, and with the addition of a few other bits making a moulded
'adapted' bonnet out of glassfibre myself. (which would prove usefull to other builders tho are looking to do the same.
Looking at the Plenum itself i think it is made from cast alloy, which i believe most welders wont touch

Cast alloy is weldable, iv'e had my sump chopped and rewelded with no problems.
As long as the thing is clean and any coatings are removed prior to welding.
I think what puts a lot of welders off is when you turn up clutching a handful of painted,oily, mis- fitting parts, they know from experience that the
job spells trouble. If on the other hand you do all the preparation for them,weldings the easy bit.

A trustworthy source on the Swedish locost list encourage people to build there own plenums out of 3" exhaust pipe. Make it the same volume,
weld on studs and connect to the cut off inlet with short rubber houses (the "wavy" radiator kind). And as Steve say, the length of the
inlet will affect the character of the motor.

Note to all: I really don't know when to leave well alone. I tried to get clever with the mods, then when they gave me a lifeline to see the
error of my ways, I tried to incite more trouble via u2u. So now I'm banned, never to return again. They should have done it years ago!

Sorry, only hearsay so far, I'll drop a question on the Swedish list.
