Rs2 with boost

[batesey]

Right!! I've heard a few rumours that the rs2 inlet won't work with boost but I can't see why? Only thing I feel the problems would be is keeping the sensors in and that can't be hard to overcome?
Has anyone ever tried it?

I like the idea of it to be honest and want to see if anyone has any facts on the subject before I waste my money

 

[v16daf]

Yeah sensors would pop out. Is the manifold robust enough to handle pressure?

 

[theduck]

pretty sure the principle is spot on, but that the reality is there is nowt to gain by doing both. If there was a gain to be had, chip would have done it by now

 

[BIGASH]

I don't personally think it will take the boost but I could be wrong!

 

[MG cup]

It would work on a low boost turbo safely I would say but the walls are crazy thin on parts of them RS2's and would worry me, its also not really needed as the a turbo forces air in so doesn't see the restrictions of an N/A engine. It would create more lag too as its just another area that needs to be filled with air.

The sensors in the standard inlet are no issue on boosted cars so these will be no issue.

Superglue will solve anything

 

[Bobby.]

Their was a chap on here from Norfolk on here that attempted this, but I don't think he finished it.

This come up in convo before, the conclusion was, it's not worth it with boost, a standard mani will be just as effective.

 

[brucey106]

I had a sensor pop out when I tried 26 psi by accident! Some super glue sorted this issue. Is this the same inlet??

 

[aucky]

If you had one lying about, why not, not much point in buying one specifically for it though.

 

[Bobby.]

No Bruce, that's a standard inlet manifold. The RS-2 is an aftermarket manifold.

Lots of big horse power turbo cars run big inlets.

With big turbos and 8 injectors typically IME. Ford Motorsport YB 202 manifold for example.

I think it would work quite well and the quality of the carbon is very good so I think it would stand upto moderate boost ok, if you ever try and drill through it you will see what I mean.
certainly be a bonus on a turbo having easy access to the plugs as well. But all that said its a lot of money when the standard inlet will easily do 400 bhp with boost anyway and if you use a 197 one (with the head) you can get at the plugs anyway.

its very similar volume to an rs200 plenum, and those work very well

 

[MG cup]

Clio rs200? I'm sure it does work fine and probably less volume to fill in heinsight than the standard 1*2 inlet but my point was getting at bigger isn't always better.

 

[Chip-mk1]

No mate. The reliant/ford group b car rs200.

 

[MG cup]

I thought that's what you meant, with talk of both Ford and Renault plenum's I wasn't sure.

 

[brucey106]

No Bruce, that's a standard inlet manifold. The RS-2 is an aftermarket manifold.

Ah sorry, is that like an old jms inlet?

 

[Bobby.]

Yeah that's it.

 

[Chip-mk1]

Ah sorry, is that like an old jms inlet?

Like this mate:

 

[Fred@BTM]

just drill and tap a fitting onto the inlet and then remote mount the MAP with pipes and clip etc?

 

[VikkiB]

Low boost applications would be fine I'd have thought, Dan's supercharged one is seeing 10psi and the sensor hasn't popped out the stock inlet, so wouldn't be any different on the rs2?

 

[brucey106]

Like this mate:

That's a nice direct inlet. I would like mine to have one of them

We had a customer purchase an RS2 Inlet manifold to run boost last year from Russia, We have never run test's in house to guarantee the safe operation but the only changes made were to the M.A.P & A.I.T sensor locations, instead of being installed to the plenum chamber they were fitted to the aluminium backing plate with brackets to stop the sensors being forced out under positive pressure.

The customer has still not completed the build so I can't comment on the outcome but his reason for choosing the RS2 Inlet manifold was to be able to run a decent exhaust manifold/ Turbo set up that would otherwise be impossible with the location of the standard inlet manifold, those that have boosted the standard inlet know how tight the manifold coming from the turbo exhaust side to the cat-back/decat is.

 

[Cup_Phil]

You could even run the PMS exhaust manifold!!

 

[Chip-mk1]

For a turbo? lol

On an SC car though you could and I would expect it to work quite well TBH, although im not really sure it would make enough difference to justify the cost, but that is true of the RS2 on a boosted application too really.

 

[Cup_Phil]

Yeah - you'd have to modify and weld quite extensively, but I bet they flow well!

If using on a turbo, there wouldnt be anything of it left as you would only use the flange and about the first 12" of pipe.

A custom manifold along similar "rams horn" lines would be one way to get a good turbo manifold sorted though.

Still cant decide if I want to do that on mine or keep the log one, I dont really want more power than it can make and they never seem to crack but it still offends me having it on my car.
