Since getting my truck I have done a lot of work to it, engine and other. It is a Defender 200TDI with 70k miles. Engine wise I have done
1. Timing belt (yes it is timed correctly)
2. Water pump, Radiator, Fan clutch
3. Head gasket / head bolts
4. Rebuilt injectors (fixed a smoking issue I was having)
5. Electric fuel pump, sedimenter, lift pump, lines
6. Cleaned intercooler
7. Valves adjusted perfect to .2mm
8. All new filters, bled, yadda yadda
Compression is 400psi on all 4, 12.5psi boost on the gauge. Added boost and EGT gauges. I have also added VDO speedo calibrated properly and verified with a phone app, added VDO water temp gauge wired properly with separate ground.
LT77 tranny, 1.4 T-case, 265/70 tires on Wolf wheels.
I have brush bar, rear ladder, tree guards, Mantec with full size spare, rear step bumper, surf racks, NAS SW roll cage. (Things that would affect aerodynamics)
This truck doesn't really want to go above 70mph. I was coming home from the beach today with 2 long boards on the roof, it was pretty windy, I felt I was killing it trying to maintain 65, temp 195ish water temps, EGT 1100-1250. Later this afternoon I was able to get it up to 75mph killing it on highway, no boards on roof, didn't feel safe continuing at those speeds, temp gauge was reading about 200 at that speed. EGT's were 1250.
I feel like the truck consumes a good amount of fuel. It doesn't smoke at all. I doubt the injection pump was ever messed with.
---------------------------------------------------
Reading about other peoples 200's on this forum I should be able to "cruise easily" at 75mph (not sure how thats possible with the engine screaming) through the mountains, upwards of 85mph (how the f*ck? No way am I taking this thing another 10mph if it would ever get there, even if it could, which it cant), with 800 degree cruising EGT's, 185 operating temps, getting 30mpg.
Mine will do 75mph at 1250 EGT's and 200 degree water temps killing it foot to the floor on a good day. It will cruise pretty easily at 65mph, 190-192ish temps, 900ish temps with no boards on the roof.
So what is the real story, are these numbers some internet unobtanium BS? Or is something still wrong here. Can/do people actually do 85mph in these trucks? Is cruising at 75 really 'no problem' (as in all the time not just with a tail wind killing it foot to the floor)? Does your truck really never get any warmer then the 190 degree T-stat temp? Is it because of all of the stuff bolted onto the outside of my truck?
I keep throwing money at this thing chasing some 200tdi inferiority complex with no luck. I have a bunch of time and money into it making everything right. I am a competent mechanic, everything is in top shape, engine is heathy.
I will keep throwing money at it if I really are not running how I should, but after all this, I feel like I might be getting led on.
I just ordered a bigger intercooler, however not expecting it to do much. Certainly not drop temps hundreds of degrees and give me another 10mph.
End rant.
