noise of 200Tdi in a series

[Jimmy]

just wondering how noisey a 200TDi would be when dumped in a series 3 ragtop.

Probably about the same as the 2.25 diesel, I expect, or just as noisy as it would be in a Defender ragtop. Not as noisy as in one with a metal roof, that's for sure, but noisier than a wagon with at least some sound proofing. It may actually be a bit quieter than the 2.25 diesel, as the engine is significantly lower compression ratio.

Thanks John, but not having had a 2.25 I don't know how noisy they are. I've had a defender TD5 and those little engines can be a touch noisy, are they similar? I kinda figured that the ragtop would make it pretty noisy driving about, particularly at speed.

The Td5 is a lot quieter than the 2.25 or the 200Tdi. The ragtop minimises engine/transmission noise, as with the enclosed bodies you get both echoes back and the panels acting as sounding boards. On the other hand, you get a lot of road and wind noise with the rag top, and unless it is properly fitted and tightened, in some circumstances a lot of flapping canvas, although properly set up this should be minimal. But most Series Landrovers give a lot of wind noise because none of the door seals work very well, and a lot of road (and engine/transmission) noise because there is no insulation.

I have a 300 tdi 90 rag top defender and a 110 300 tdi station wagon and the 90 engine sounds quiter than the 110. I believe this is down to all the other noises you get in a ragtop that drown out the sound of the engine

BTW there is not alot of difference between a 300 tdi noise and a 200 tdi noise

I have a 2.25D in a 109" ute. I also have a 300Tdi disco. We bought a few packets of ear plugs before we drove it from Brisbane-Perth. :D

With earplugs you can just manage to hear the radio on full...

The 200/300tdi would be no noisier. If anything it may be quieter. However at 100kph you are doing 3600 rpm. Fitting a 5-speed when you fit the engine would make things significantly quieter.

[Jimmy]

thanks crew, I think the 5speed box mated to series transfer is the go and I can handle some nosie just wondering if it was going to be extreme.

I remember riding in a 200tdi Disco years ago and the engine clatter at 100km/h was starting to become intrusive.

So with the 200tdi going into into my uninsulated S3, I expect the racket to be appalling; therefore; my plan is to insulate the gearbox cover and the bulkhead closest to the engine with a lead sandwich and under the seat-box, bonnet and the rest of the bulkhead, with cheaper and lighter acoustic insulation,

my series 3 truckcab is quite respectable in my opinion (noisewise) in the cab with it's 200tdi under the bonnet, i've got a 3mm ribbed rubber sheet covering both footwells and the tunnel in one piece along with a heavy rubber/cloth mat in each footwell

i do have 3.54 diffs and a nice quiet overdrive for road use which brings the revs down nicely at 65-70mph on the motorway, i find it's even better if i can take the doortops off as this reduces the reflected noise, there's little point in turning my radio on unless i'm trundling around slowish or sat in a traffic jam...

on the other hand my 109 series 2a with 200tdi that i've just built is about as noisy as you can get, van bodied, 4.7 diffs and no overdrive, minimal matting/floor covering, 45mph is as fast as you can go at almost bearable noise levels (although i've seen 70mph on the clock), diff swap, mats and an overdrive are on the cards for future use
