I have a TD4 auto 2002

Rover ron fitted and EGR cleaned and blanked off

Question is

Should you feel the turbo come in, I can here a whistle of turbo at about 1800rpm give or take but i wouldnt say it sweeps the car up in acceleration like any normal Turbo diesel car, Its hardly noticible

It performs ok since the roverron fitted and not really bad enough to say something is wrong but i wouldnt say it had a lot of torque

Interested to hear what others think, I bought the first one i saw and have never driven any other

Thanks
 
Don't panic. I have one, and I have driven a couple of others. The turbo seems quite smooth and progressive. I too can hear it whistling about 1500 revs when its pulling under load, but it seems a lot smoother than other (older) turbos I have driven in the past, where you were more than aware of when it kicked in.

Bear in mind, she's a heavy old beast too !
 
Shutty i have a roverron gismo fited and although mine is not an auto i have the same question as you.While there is an improvement in performance its not exactly putting you back in the seat.What should one expect?? i just dont know.I suppose the thing to remember is that it is a 2L oil burning 4x4 not a light wieght petrol car.But what is exceptable and what is not when it comes to 4x4 performance.
 
I always look at it that it can easily keep up with the traffic on the motorway, with enough left to overtake. It's never going to outpace someone off the lights, or even on a straight sprint, but if you want that, a 4x4 int the thing to have.

(yes I know that a lot of specially prepared 4x4's are more than speed capable, e.g. VW Toureg, but generally, you wouldn't by a 4x4 to race on the road any more than you'd try taking an F1 car off road)
 
no noticable turbo cut in on mine either

for what it is(car based 4x4) it pulls well, keeps up with traffic, great all rounder

what settings are you on with the tuning box ?

I assume you all mean a Synergy, not a Mafam MF75p?

I would have expected setting 3, 6, 9 7 10 to produce quite a noticeable improvement in turbo build up from just over 1500rpm. But even on the lighter 75 & ZT the turbo is still fairly progressive compared to say, my X-type (2L Mondeo engine). This has a much more pronounced surge at 1700rpm which I put down to the electronically controlled variable geometry turbo. Ditto VAG diesels.

I think an egr bypass will help though.

Sounds fine. Can't feel the turbo on mine. Pulls pretty strongly all the way through the revs. No surge at all. My diesel new shape Laguna was the same (although that had bad turbo lag if you got the gears wrong!). Only modern turbo diesel I've "felt" the turbo was my Golf GT TDI that I had a few years ago. Yours sounds OK to me.

Cheers

Hi Ron

No its just the Mafam at moment and EGR has been bypassed

That explains it. The mafam won't boost the torque above what is supposed to be there with a good maf. A Synergy 1 or 2 will and there will be no mistaking the effect the turbo has.

Got till January on current insurance and then will probabley go this route

At present Budget Insurance will take great joy in limb removal with only 2 months to go

Charged me £25 to change car (+ £90 additional premium) and then £25 to move house, But the premium came down by £2 when i moved house !
