Engine mods

[Christophe]

Not sure where to go next with what i have got already. Currently have full ss system and bmc induction kit. What should i look at next?

I like the sound of ITB's but way too expensive. Dont really know much on engines but hear a lot about matched inlets, cams etc. are changing these worth it and how much i'm i looking for these.

or i could just get a remap but not sure i'll gain much with out other mods in place.

 

[bing_17]

Can't believe its not mapped already you seriously will never look back. Get a RStuner ordered and do it!!

 

[Christophe]

If i was to get it mapped would be at rstuning. will there be much point with out any other mods?

 

[Aluco]

Unless your going down the cams etc route a map is about all you have left, decat maybe first.

 

[Christophe]

how much would i be looking at for cams

 

[Aluco]

not asking the right person :rasp:

but I imagine fitting will be fairly expensive unless you can do it yourself as its internal engine work isn't it ?

 

[Christophe]

anyone any ideas on how much cams are?

 

[Icarus]

Short runner direct path inlet manifold is the much more cost effective alternative to ITB's as it allows you to retain the standard ECU and wiring loom along with traction control, cruise control and the DBW throttle body. As the standard ECU is retained cold start is also as per standard.

It's not far off now chaps and I honestly think it will be the best bang per buck mod going for a 1*2.

Looking forward to hearing more news about this!

Any idea on dates etc.? You want a PH-1 172 to do "testing" on

 

[Icarus]

Might well do to see what is required for a cable TB car as this has specificaly been a DBW prototyping excersise so far.

To clarify this will be essentialy a direct bolt on to any 1*2, FF/Aircon equiped or Cup. Sensors will be relocated on the plenum but PNP loom extensions will be included so no hassled there. The standard loom spur to the DBW throttle body will need recrimping with a Superseal/Weatherpack connector but thats about 5 mins work. Aside from that the loom remains unchanged.

The inlet manifold itself is a vast improvement on the standard manifold. No bends/90 degree turns and a proper trumpet in side of plenum design for much improved flow and velocity.

They'll be a map available off the shelf for it or you can have it custom mapped to suit any other modifications.

I'm not going to make any power claims until its been on the rollers and gains are proven, however it should be 'blimmin' good ;-)

sounds interesting stuff ^^^

 

[mattjk]

+1 with geesus, looking forward to hearing more ;-)

 

[Cro]

Sounds very interesting indeed! I take it the cost will be something similar?

 

[Icarus]

Similar to ITB's? Nope - the cost will be no where near what an ITB setup will cost. You don't need an aftermarket ECU, or a wiring loom, you retain all the standard sensors and its about 1/3 the time to fit + you don't need to change rads or cut the car.

The gains won't be as high as what an ITB setup can provide - simply because you are still using a single butterfly to feed all four cylinders via a plenum. However I'm confident it will show extremely good gains - as I said in Bang For Buck terms I don't think anything will get close!

Cheers

[geesus69]

at a complete guess it will mean the inlet butterfly will be alot closer to the slam panel? (i've got an image of what it might look like, sort of like an ITB airbox companies do for the 106 gti but using the single butterfly?)

 

[Icarus]

Yep the throttle body will be at the front of the bay. Allowing an open element air filter or air box to be located in the part of the bay with the best ambient airfeed and the coolest ambient temperatures with a direct feed from filter into the throttle body, again to minimise any losses.

Cheers

[geesus69]

i will be waiting news on this then

as long as it can be used on cable throttle it would be ideal for my mk1, big hole in the bonnet for the inlet......bob's your uncle :approve:

 

[Russ.]

Lol come on Icarus have a guess at bhp/torque figures. Any likelyhood of touching the magic 200bhp?

 

[caister]

Sounds good how long do you think it'll be till its ready?

 

[Cro]

Sounds perfect to keep the dbw, standard ecu and still an option of using cams :approve: stick me down!

 

[Christophe]

would matched inlets help improve my car?

 

[Bazzon]

I know what hes wanting but :nono: im keeping shhhhhhhhh till he knows for sure :approve:

 

[GazM]

Have a check if you have the "RS" Stamped inlets mate, if you havn't (which is very possible on a 172) matched inlets would be a great mod, still so even if you have th RS ones.

IMO cams aren't any good without ITB's, your looking at £1000 for cams fitted with only about 5-9bhp gained.

If i were you i'd get a decat or even better would be a 182 manifold and decat but this could be alot of work as you might need a new exhaust.

Id definatly recommend the RS tuner, especially if you get a decat as you can turn the emisions light off with it. I know RS tuning is very well respected but personally for the money on a clio i'd used the RS Tuner (@ £150 its a bargin), if i had a turbo'd car i'd definatly take it to RS Tuning though!

Hope this helps

 

[BenR]

Cable fitment will be exactly the same, so no problems there. Just a slight modification to locate the ICV, most likely remotely with a hose extension.

cheers mate. How much is a decat and does this fail mot's? you think if i got matched inlets and then a remap i'd notice a difference?

I thought of getting the RS tuner but i wouldnt know how to do it and i would get pissed off trying to find the right patch for my car.

 

[Christophe]

how do i find out if my inlets have RS on them? Where abouts are they.

 

[Icarus]

Sorry but I'm not going to post guestimates. It's just not worth it as its not actually any use to anyone! It will be a very positive improvement but I'll only post figures when I can post the before and after graphs to go along with them. Otherwise its just speculation.

Ben has the prototype in build (and its looking excellent), various bits are on their way and I hope to run my car on the dyno with the new plenum setup and a fresh engine (as my current one is waaayyy down on compression) end of Feb. At that point all the specs, info, pics and figures will be posted along with cost.

The RS lettering is in the casting on the lower inlet manifold on the rad side of the runners in big letters.

^ Shall be eagerly awaiting the results of these mate. Sounds like your very much onto a winner to me.

that's what i like to hear!

look forward to hearing more
