yellow inlet manifold

[jimbo1]

heres my newly sprayed yellow inlet manifold and black exhasut manifold. im well happy;

looks good mate

i like very much the rocker cover, where did you get the badge from? and does it stand the heat? it is exactly what i was planning to do with the top of my williams engine, the inlet manifold i was thinking was thinking of doing too, probably alloy wheels paint silver to match the rocker cover, how tricky is it to get the cam belt cover and inlet manifold off?

also that must be a 19 16v lump (which you drive of course) because the oil breather pipe is differnt, mine come down the front and into the bottom of the air box

Nice wann do summit similar to mine Dunno bout taking the engine out though!

 

[16V_Matt]

Im cinda lame at stuff like that!

Could u do it with the engine in?

 

[jimbo1]

yeah those williams badges i had made up. 15quid for 4 in silver colour. ive got them on me car as well. looks ace in silver. i used hammerite on the rocker cover and inlet manifold. used hammerite bbq paint on the exhasut manifold, resists upto 500degrees c-soon see if it holds

[jimbo1]

yeah, removing the rocker cover is easy. the inlet manifold is a bit more challenging with the head still on. jsut need long extender bars to reach the manifold nuts. wudnt even attempt the exhaust manifold with the head or engine in the car. no access

Jimbo that looks wicked mate. BTW I have actually removed an exhaust manifold with the engine intact. Not fun, but it can be done.

Actually I need your help on a couple of things Jimbo, first can the inlet manifold be taken off without having to take the rad off or disturb the alternator?

Also have you got the original high res picture of your inlet manifold that you could email me mailto:nick@cliosport.net">nick@cliosport.net ?

I need to have a closer look at where Im gonna hook up another four nitrous injectors into the manifold runners and its easier to imagine it with your pic (all the wiring etc out of the way)

 

[jimbo1]

hi nick, on the 19 id remove the rad ad fan to do it, so on a clio it wud be even less space. removing the rad takes 2mins anyway!! check ur mail

wouldnt bother with the nitrous injectors in the manifold nick.. wont make any difference at all.. in fact it will RAISE the induction temps leading to more r****d...

 

[Nick Read]

I assume youve got proven data on this Joe? How do you explain the raised induction temps...surely the opposite would be true because rather than a proportion of the liquid fuel/nitrous charge being wasted lining the walls of the manifold before it atomises, the whole lot will be used, thus lowering the charge temp further that at present, and also delivering a larger charge into the cylinders?

Also totally gets rid of the problem of uneven charges in each cylinder.

 

[Captain Slarty]

no dood, it dont work like that...

the spraying of gas / fuel prior to the throttle plate on a plenum system allows considerable cooling of the total air in the plenum.. by restricting it to single ports you will lose the time factor for the cooling to propogate.. thats the issue.. and hence the reason overall charge temps are higher.

As for even distibultion.. if you had a poor design of manifold then maybe, but you havent... so it wont..

[Nick Read]

Nice to have a sensible answer Joe. So would you say that the charge cooling effect through the long induction tract outweighs the benefits of the full nitrous/fuel flow being injected almost directly into the ports with no loss of mixture on the way?

 

[Ben j]

ahhhhhhhhhhhhhhhhhhhhhhhh

tooooo techy for me... im off! http://www.stopstart.fsnet.co.uk/new/cookie3.gif

 

[BenR]

hmmmmm......

i would think that the cooling effect would kinda be offset by the break down of the liquid then gas into 2 seperate elements....so itlll be less dense...but then.....that might not happen.....and the map sensor would go a bit weird...with all that pressure changes.

injecting it DRIECT inot the ports would mean you were running on a mixture of thats pure out of teh bottle....is that good?

i guess its a suck it and see excecise.

 

[Pysco]

The further from the ports the injectors are the better the cooling effect is, as Joe said, spoken to Trev. and he rekons on injected cars one injector is best anyhow, for the reasons Joes mentioned.

The map sensor wouldnt be affected as there is no pressure change, the systems not be positivly charged just the charge is being made denser.

There is no way the N2O could break down in the manifold, its no here near hot enough.

 

[BenR]

yeah, mine a really basic setup on a carbed car, and i pass it over the main jet to take fuel off that too........

on the 16V tho, ther aint much space to inject it before the manifold........

so, maybe a twin crossfire setup before the TB would be ok.....

agai, itll be a trail by error system
