Little update here too. Made some fueling upgrades and minor turbo upgrades on the wintertime. Did visit the same dyno to see comparable results.
This time it was pretty decent power gains. Unfortunately car went to limp on the dyno but nevertheless it reached 469hp (4800rpm)/768nm(3800rpm). On...
If you going to full 3". Add atleast good flow cat and some end silencer. I had one that had 3" in and two 2.5" out. Added flap to second output and it droped exhaust noise about -14db when closed. At track they measured before 103db and after the flap mod 89db. It was vacuum controlled by n75...
Grave digging here. I have not been much on the forum lately but i want to make upgrade post to this thread. Last few years i have slowly building my b5 2.5tdi with three turbos compound setup. I have currently runnin just bit over 400hp and i believe there is lot of power left on table. My...
I would not to be worried about running big power and big kilometers. My car is on everyday use and used on my daily job so last year I run with it almost 40k. I've done+ 210k in 7 years, so know what I'm talkin about. :D
It's never good when you need to do some "tricks" to get fuel out, but...
Oh dear. What a old topic. :)
These pumps are very mysterious. Pumps them selfs are not limited but but duration is limited. That means that you can bypass stock nozzle limits by changing bigger nozzles. So lets say most of the pumps
are "limited" to 52-54mg/stroke. That is just calculated...
It's still full custom tunable. You just need to do some little soldering to add chip sockets to your ecu. Then it takes few minutes to change software.
In most cases when starting with semi-cold/warm engine are caused by slightly late timed vp44. You can test it by unpluging the temp-sensor located left side of the pump and you will get full glow and nice start. :)
Nice troll, Craig. :D
Back to business...
I looked my setups and looks like 9" wheels with ET37 are fine on front and ET34 rear with the same tire (235/40/18). When using 225/40 tires even ET40 is fine. If you are gonna ride ridiculously low I recommend to use 225 tires. ;)
Using spacers (approx. 10mm will do the trick) and 225/40/18 tyres and it will be ok. I'm currently running 9"x18" wheels with et37 front and et34 rear with 235/40/18 tyres on. Because running pretty downlow there are some rubbing appearing in my case. ;)
Why drop in 180hp version? It's the same as 150hp version. Wasting your money. All the nozzles are same flowrate - old ones
have 5x0.18mm and newers 6x0.16mm holes, difference is in pumps / ecu iq-rate. You will have same output power with 150hp
and 180hp engines, 180hp and newer 2001-> engines...
With stock head, dss ultime 2 nozzles, gtb1756v you get around 230hp/500nm. That sure includes fmic and clutch upgrade.
After that serious mods needs to be done, better cam 260/9.5mm, bigger distribution head, ported head and maybe even add gridle.
Nothing that much. All parts are almost stock, even they are from different engines.
-base engine 150hp AKN
-ported/cleaned heads BDG
-pistons from AKE
-stock/hybrid turbo with wheels: 44.5x60comp / 50x45turbine (from e61 bmw)
-fuel pump with AKE distribution head
-nozzles from cummins 5.9l cr...
Yea well. I've new dynosheets;
277/1.6bar and 267/1.5bar. We really needed to drop iq above 4000rpm because the emp is getting really high (2.5bar).
But I think it's really good for that small turbo I have, gt2060v - means e61 beemer 30d wheels inside the stock turbo.
Little video too;
