New K-Tec Manifold

[Il lungo]

the white to the airbox or filter and the black to otherthing ^^ i think

Similar to the manifold for the C2R2

It will likely be, White - Airbox, Black - Gearbox Oil Cooler.

BUT anyways guys, this is a Twingo Manifold discussion
SO, Back to topic

The issue is with the R2 Manifold, is they don't like working with VVT allegedly...

P.S - If you search "Twingo R2 Manifold" into google images, the vast majority of the 1st images are from this site...

Well, I've had this on for two weeks now


Fitting was a bit of a pain, but purely because getting the original manifold out is a tight fit. Needing the right hand drive shaft and lower engine mounting to be removed, before swinging the bottom of the engine forwards a bit, to get the old manifold and cat out past the subfame.

I extended both the Lambda cables by chopping them near the connectors and adding in wire to reach the new position, using some Adhesive lined heatshrink crimps to get a reliable water proof joint.

Sounds the nuts Neil

What's your verdict on the manifold? Or waiting until it's mapped with the rest of your goodies that you will be doing?

I was just on about this with Matt, so

It was funny that we booked it into the garage for 3 hours and it was just short of 6 when it rolled back out (+ an hours lunch). That was with windy tools etc and a 4 point lift for good access. It would have been longer if they also lengthened the lambda cables, but I did them whilst Thomas was swearing at the Renault manifold, not wanting to fit out past the subframe :lol:

New system is prety good and the new manifold went in very easily. As I wanted the exhaust as high as possible, I had a few rattles to begin with , either when cold or after a good blast when the exhaust grows about 6-8mm and the backbox started hitting the rear hanger. Prety well sorted now. Sounds good, with a deep note and no drone when off the throttle... but quite a bit louder than the Supersprint

If I would have a new manifold I'd put some heatwrap around it.

Heat reduction in this small engine bay is important, IMO.

But it looks & sounds awesome! Makes me wish I had the 1.6 so I could install this awesome stuff as well :?

But when it starts to unwrap itself that's going to be a pig of a job again :/

 

[MovingShadow]

In that case there's other stuff you can use:

Gold foil wrap or ceramic coating:

moving the cat out of the engine bay will probably make a difference to temp.

Doesn't sound all that loud from the video (but it does sound nice, not farty at all like most small engine jobs); what's it like inside - particularly cruising at 70?

The sound, how noisy etc is always going to be very subjective as everyones ears are different and up till now, the carbon airbox was probably louder than the exhaust. Now, it semls to be fairly evenly split between induction and exhaust

As a guide, with the stereo Speed volume adjustment set to 0, no fade and balance adjustment. Pop setting
BBC R1 news reports (normaly a fairly standard volume broadcast) can still be followed at 10-12 volume at 70mph when off throttle/cruising at constant speed
14 volume needed for maintaining 70mph on throttle up a slight incline
18+ volume needed when at over 6K and accelerating hard

mmm, it doesnt sound that loud to my ears either. little pop on gear change and a bit throaty tho. may be remove that middle silencer, if ones fitted? not sure on the slash cut tail pipe... :|

Admittedly not Radio 1, but I need to set mine to minimum 20 to comfortably hear speaking or music on Real XS, CDs more like 25!

Edit: Ah, but you've got smaller wheels and wider tyres...

looking at the k tec site pics of the system, they dont do a straight through middle section, tho good to hear the rear tail pipe is clamped on, should it need changing so which is loudest, supersprint or k tec?

 

[Matt]

Larger engines and forced induction cry out for larger exhausts as the higher displacement means more gases.

Why is noise so important?...

I'm interested in lack of volume, primarily. Wanting it to not sound like a Barryed-up Corsa comes second.

My stock car is already more than noisy enough at 70; that's largely road noise and 15" wheels should help. At 80, intake/engine noise take over and a longer 5th will help with that.

I do want to increase torque though, which will mean intake, exhaust, possibly cams if they provide a good increase, and a remap. My choices here, if I ever make any, will be at least partially guided by noise.

Currently running 17" cup wheels and 205/40/17 BF Goodrich profillers.

20 is plenty loud and 25 would be getting silly. And i'm cat 2 deaf mid range :?

The New K-tec system is cetainly louder than the catback Supersprint by a fair margin. The volume from the Supersprint being comparable to standard levels or quieter with the rear two sections connected to the renault front pipe and slightly louder but still very livable with the full system as it has a large backbox and standard 50mm pipework.

That's weird; mine comes on at 15 and I always have to turn it up. :? Hardly critical though!

Cheers for the comparisons. So the supersprint catback with k-tec manifold and race cat (if I understand the k-tec website that should work...) should be quieter than the full k-tec system? Then again, cost becomes a significant factor there.
