Inlet Manifold

[SCS j1mbo]

Steve, we have had two inlet failures daves for a unknown reason so far, and another that looked identical.

The reason behind the other was a fuel pressure regulator fault, it filled the inlet manifold with fuel and parted it wide open exactly like daves when ignited, I beleive the customer told us he had a peak reading of over 200 psi.

We have had no other issues. And they're a very good inlet.the material it's made from is awesome, I don't beleive design or material is at fault, but we will find out soon. And should the customer want to clear the air it will be up to them.

Carlo,your bang on.

I`m sure this is a big interest to find out why this happened, for SCS and think they will sort it out. Remember there was a guy on pf some years ago, who craked 2 Rs200 inlet

I would be very interested to know the outcome or even your best guess (by PM if no one wants to go public) as I have my own theory as I have seen manifolds split like that before.

Steve

Why don't you give your input then Steve everyone else has

A chance to get to the bottom of the problem would be nice!

ah what have i missed lol

It was my m8 Jim who cracked 2 rs200 inlets in 2009 well remembered m8

He still hasn't got to the bottom of it but believes it was deffo a backfire that did it but not why

[warrenpenalver]

200 psi in the inlet! ouch!! that would burst pretty much anything!!

[WENNY]

200psi wtf sensor did he have readintg that in his inlet lol

Expensive day out there Steve

[Chocky]

I suppose it's always good to have that burst when things go wrong rather than
Blowing the whole inlet off the head and wrecking the head etc.
Always try and look on the bright side or

jim I was just shocked how fuck bad it split out if it happened to me 3 times I'd be changing manifolds
No need to get fucking pissy poor old Dave must be pissed right off
By now

Way I see it cossyking and cossiedavid love the threads when something to do with scs goes wrong , if it was a scs fault I know they are itching constantly to get on the wagon ! It may be a scs fault it's how they deal with it and move forward that counts so I can see the reason for binning the thread originally due to this also

It's not that at all if Harvey or jim thinks I'm slating them off I'm shore they would phone me there big enough lads Harvey and the team have been good to me over the years Si why would I want to fucking slate them off

[Carlo]

You tell me ! im looking from the outside in & its clear you & your mate have a hardon when something isnt right with a scs powered car your use of them on the threads says it all like when the thread dissapeared ! i had texts from two different people last night agreeing with what i put above & someone on this thread has agreed also ! im not paranoid or tripping i know what i see.
Its clear you and cossyking have beef with scs from reading past threads thats fine yous arent happy & will have your own reasons buit i think you should keep them to your threads relating to your complaint , thats a good few threads now yous are on with the cock out ! as for harvey or jim lifting the phone maybe they arent that kind of people to go digging people up about two trolls on the internet.

As for dave im sure he will say his peace and if scs are at fault hopefully they will get it sorted and put this to bed.

Example here you have been choking for this to fail with this reply then you deny it like you did on this thread.

I too thought it was originally a fault, but after it was removed and you could see the damage sustained, I took it back to Harvey that evening and discussed in great length and after piecing together all the evidence, it became obvious that it was nothing to do with the manifold. When Dave removed it, it still had a large quantity of fuel in it, so obviously what is happening is fuel is getting inside the plenum for some reason (weeping injectors, faulty FPR or some sort of spit back on the ignition cut when flat-shifting), and then because the car is running on wasted spark, the cylinder that is getting fired on the wasted cycle is causing the fuel inside the plenum to ignite due to the inlet valves being open, where it basically becomes a bomb .

Changing to coil on plug would stop the fuel from igniting (as there would be no "wasted" spark in the other cylinder, so no ignition source), BUT that isn't getting to the route of the problem (which is "why is fuel getting in the plenum?").

IF it had failed due to pressure alone, there would just be a small split, whereupon all the pressure would dissipate out of the hole and it would not have sufficient energy to do any further damage. If you saw the size of the hole and knew the material spec of the alloy, you would realise that this was not just pressure - it was explosive pressure (where the bang was so loud, that Dave initially thought his gearbox had blown up ).

So obviously given the above, you can see that there is no plenum on this planet that would withstand the explosive forces involved when the fuel ignites inside it.

And did I slate him there to no
