i know my 95 2.5td rolling roaded recently @ 132bhp, only mod was decat, not bad for 15year old but what figures has anyone here achieved?

[Elite Pete]

Mines chipped and i've binned the egr (not just the piping but the restrictive plunger in the egr), next up is the decat but i've never had it on a rolling road.

i know the omega is the detuned tds engine & management, and few people are recommend chippin which would bring it back up to about 150bhp, slightly above the 325tds etc.. but is it possible to use the standard tds file and map it, then write it back onto a fresh chip and fit it?guys here are getting the guts of 180bhp out of the 325tds, what is there stoppin it being done
same engine and components just diffent fuel mapping?anyone shine a bit a light on the subject

found this on another forum

''I've got a 2.5td estate. It's a 95(m reg) and I've had it over 5 years now.
The standard 2.5td only has 130bhp and is quite slow cos it's a heavy car.
I went to Collins motor sport in Congleton where they reprogramed the e.c.u. which took the power up to 160bhp. After that I got an air filter made by KnN to match any increases in power (it's big), then got rid of the cat, the middle box and put an empty volvo backbox on (take all the wool out) and it sounds great. Next I put a plate in the pipe of the e.g.r. system so only clean air goes to the engine.
Thats it for now but a bigger intercooler is next to run with the old one still in place.
I took it to Well Lane rolling road last november with the MIG Northern crowd and managed to get 181bhp and 240lb/ft torque, not bad for a car that's now done 150k.''

sounds good!!!

The 325TDS maps I tried in mine didn't work.  Even the Omega maps are not interchangable - there are 4 different ECUs fitted to UK spec Omegas (ie, U25DT and X25DT).

Never rolling road'd mine, pointless anyway due to autobox, so I'd be better just pulling figures out of the air.


The GM filter is hard to beat - surface area is massive, and cold fed. Pattern filters (as a drop in replacement for GM ones have around half the surface area). 'Performance' ones, eg cones, panels etc, also tend to lower performance, either due to surface area, or hot feed.

One mod defo worthwhile is playing silly beggers with the intercooler fan

I take it by this you mean taking a intercooler from a 325td/525td and sticking it somwhere on the front :-?

I think he means adding a switch so you can force the I/C fan to be on instead of normally off

ive hard wired mine to the air-con fans

[TheBoy]

Correct.

really down to a ''custom map'' and not a generic one, mines a manual gear box,

right have been onto my man that usually does the chipping for me, says his figures will leave her in the region of 172bhp (128 bhp standard) and 320nm torque(250nm standard), and that was just chipping her, add on the decat and custom made exhaust, and try and get as much cold air into her as possible, should see me in the range of 180bhp
with such a huge increase it'll be down to the rolling road to see whats what

Blank the EGR, easy bit of an increase, I have removed most of the piping from mine too (I used some of the piping the seal the exhaust end...  I need to remove the plunger from the intake end still, but worth an extra 3-5 bhp, for the cost of a small metal plate...  The chip in mine reckons to increase the power to 170 bhp, I hadn't thought about the "fixing" the IC fan, could be worth a bit too...

I don't see the point of the rolling road tbh, just to get an accurate idea of where the engine is...  I get enough fun embarassing the boy racers in there muppet motors trying to race away from the traffic lights...
