rs2 style inlet?

[Ryanph1rs]

Any one on here made one/ know of some one who can? Seems its nover engineered like say fitting bodies has any one made say an aluminium style inlet that guy from aber g is pretty trick with welding perhaps he could make something similar? Can we discuss this possible alternative to a very rare rs2? / throttle bodies money to be made in this i reckon

 

[-J-]

James still supplies the RS2 but in batches due to the cost of getting the manifolds made.

Do you need a new ecu etc to run with the Rs2 manifold?

No, get the standard one remapped

Thinking to make this myself as well. I can weld aluminium, so can make it cheap. But it is something for the future, because I have other things to do as well (mounting my Schrick cams and so on)!

That manifold seems to come up on ebay every couple of months at the moment.

There have been threads about this before and the consensus was that there isn't much money to be made. Narrow margin/low volume.

They are still being made. I bought one 6 weeks ago. Call james on 07525819307 if you want one

I got this one made and all the parts and work that went into it for me and focrs was huge. Would need to make quite a few to make it worth it and even then the margins would not be huge.

At least all the parts required have engineering drawings now so could be reproduced.

Have you got any graphs for it?

Very easy to make something that looks similar dut doesnt work as well (not saying yours doesnt, just saying its a possibility)
Does it have internal trumpets like the RS2?


I made one myself for a williams engine, parts cost was well over 500 quid and then plenty of Tig welding and time on top of that, and still with compromises on shape which the RS2 doesnt have in the context of an aircon 172 engine.


Couple of pics of mine:

Personally I think the only real way to make a quality product that competes with the RS2 for resale at a signifanctly lower cost, would be a cast one, like I have on my honda engine that is going in the mk1 shell next:

 

[Cupman29]

No graphs yet as its not been mapped yet. Hopefully soon!

I designed it to have the correct decrease in volume across the plenum to promote a consistant air supply to each cylinder. There are trumpets inside the plenum for each cylinder as well. The only compromise was the length of the runners but without removing the slam panel this was as long as I could go for. The port matching is perfect from head to trumpet as well for each joint.

Looks quite promising then.

Although must admit visually the RS2 is SO much more appealing, lol.

Designed for function more than form but anyway, all in the eyes of the beholder. Lol

Exactly!

Might sound stupid now, but does the RS2 benefit from having a carbon intake meaning the temperatures won't be as warm as a metal plenum chamber?
Just thinking

Heat absorption will be higher with metal but as its at the front of the engine in direct airflow, heat won't be an issue.

Also, an RS2 wouldn't be any use for me as mine is for a turbo build so needs to cope with boost.

Interesting thread I'm going to have a go at making my own in the next couple of weeks

 

[Ryanph1rs]

Hmm Impressed with these results! If it gave a true gain of 10-15 boho it would be worth £800 all day long as that's what cams go by ( roughly )so that a set of cams and a map to see close to 200bhp for 1600 on this car isn't too bad atall ...... I only ask as personally I like the look of a polished Ali inlet more than the carbon and over the next 4 months I'd like to get an rs2 and cam and map my car I'd love bodies but I can't see that for nearly 3k I wouldn't be just as happy with the results of the rs2 ..... Keep,posting see what people are building....l the decrease is airflow is certainly a hard one to calculate and I'm really impressed with that inlet ......... Maybe some one will fancy making a few whose in the trade

 

[focrs]

I may one for sale in next few weeks if I get a chance to finish it.

Looks like the dipstick is more accessible on this one. .

Still difficult unfortunately. You need to take the upper grill off but after that it is fine.

 

[marinemackay2003]

I'm in the process of designing my own too
