I've always thought you need to be going 90mph + for ramair to have any affect, anyone have any knowledge on this?
Anything over about 50mph and you'll start getting a measurable increase in pressure, I read an artical on t'interwebs saying 112 was where the difference became apparent on a side by side (with motorbikes). Depends on ibtake size etc though. Need to get a pressure gauge on the air box...
Do itWhats an airbox?!
I could stick my intake trumpets out of the bonnet scoop instead!
bit of mesh over the front jobs a goodun!Do it
Exactly.... have em poking out the front bumper why not ehbit of mesh over the front jobs a goodun!

Oh we're getting serious nowlol why not!
I wonder if having more air directed at the inlet would help raise the dashpot slide up? @Frank & help get rid of the lag of the slides opening / as well as trying a softer spring.
Every little helps until ITB's make an appearance
You could put thinner oil in the dashpots, but it gets a bit... fluttery? best way I can think to describe it. Assuming you have dashpot oil
Lost now.... oil... in carb? That's newYou could put thinner oil in the dashpots, but it gets a bit... fluttery? best way I can think to describe it. Assuming you have dashpot oil

Well it can only help to have flowing into them directly rather than them trying to pull air from the established air stream ?

Ahhh that makes senseView attachment 26339
In an SU, there is damper oil under that green ball bit in the middle to dampen the movement of the whole thing, stops the cylinder bouncing against the spring and the air pressure and giving eratic fueling.
Yup, it's temp rated food grade pipe I 'acquired' lolNice gradual bend on yours too andy, will help flow. Smooth bore piping too?
Ram air doesn't make a significant difference to power until about 112mph, and until then that massive intake diameter will see very low air speeds, so you lose the inertial supercharging which loses you power...This was my best option. Dump the inlet manifold and ram some air straight in lol.
With what other mods though? I guarantee you won't notice any gains with that setup without other mods (exhaust mostly) as on the stock setup its not the greatest restriction (a system will only flow as well as the greatest restriction which is the exhaust manifold and backbox from what I've seen)Having had a lot of micras from 2 litre turbos to 1 litre turbos from semi tuned to crazy tuned. This is the best style of induction I have ever placed on a car. Mapped or not mapped you can feel the difference. With a 0-60 of 7.34 seconds on a 1.3 there's no question it helps
ahh gotcha yes i ran the blue car like that, you need to account for the movement of the engine, but you get some nice induction roar through the heater ductingthe part between windshield and bonnet where the air for your interior is being pulled from.
