N54 GC upgrade build
- Thread starter 135boost
- Start date
That 1435 Kg is with tank full of E85, 50 liter of it.
About build, like i told before, i have quite good situation on builds like this, cause of
resources of tools, small pieces and bits and facilities. i lifter up the car some 50cm and took hood off.
after that i put the engine hanging on a crane 2000kg crane hanging and took away
subframe with steering racket and front wheels. then it was quite handy to swap those turbos cause i could adjust engine height as needed up and down. it helped that
shotgun double barrel HPFP install too quite a bit.
the most important of build is to do everything in right order and Vargas installation
guide helped a lot. last time with turbo swap we did it without dropping subframe and it was a mess,took more time and wasn`t sure everything is properly on it`s place. now it took it`s time but had time to finetune every part to my standards.

It`s not the max hp glory pull on dyno(even virtual one), it`s more like a powerband and there it
feels scary fast at least with those pilot sports cup2?s. remember it`s allmost winter here and streets are icecold.
yesterday we had some +5c so it was warmer day but streets are a bit wet and slushy of saltconsentrate they
spray on it so i have some degree of grip issues.

asking how does it feel ....
something like this on dry and 4th gear with high boost settings .. some 27 psi
pull was with 4th from some 1500 rpm WOT and strange things happend on 3200rpm, lifted up, pushhed
again wot and second lift at 4500rpm.. third time wot and again lifted up at 5000rpm..
call it a rubberburner

Ha... finnish guy..P33P33.. write on finnish language. Finnish Bmw club BTFC.
En ole BTFC jäsen vaikka taitaa useampikin duunari meillä olla.
tämä 135 projekti oli vahinko-ostos vaimon kauppakassiksi ja jäi muutaman sattuman takia minulle
leikkikaluksi. voisi tulla meillä duunissa enemmänkin polemiikkia jos tästä kovin julkisesti kirjoittelisin
BTFC foorumille jonka takia on jäänyt se tekemättä. paljon varmasti olisi teknistä taustaa tarjota sinne
koska olen näiden lelujen kanssa touhunnut 30v erilaisien turboprätkien ja autojen osalta ja
siinä sivussa toiminut menaanikkona drag racingissä, jokkiksessa, rallissa, etc..
Hyvä sleeperhän tämä on mistä harva tietää, tosin meinaan ensivuonnakin käydä raapasemassa jonkun mailin ja jonkun
lyhyemmänkin kiskaisun.

does anyone here had struggle with 29F1 fault code ?
on my logs it seems to keep LFPF normal very steady and suddenly 29F1 and kill hfpf
and limp mode. that came up few weeks ago to me.
i have done some problem solving tests on it and it seems to trig fault code when start cold -4 to +4 degree
engine and leave it run on idle for some few minutes. tested it on + 20c and it didn`t show up then.
if i after starting the engine don`t leave it on idle, just drive away, it does not trig it.
somewhere read that it was a tune issue and went away with mods on tune, just qurious, maybe that tune
mod was "kill the fault code" or maybe a solution why it trig it.
i did so many mods at same time before it show up so it`s unpossible to pinpoint what mod did it.
- temp drop in finland
- double barrel shotgun hfpf
- tune
- GC turbos
- bunch of supporting parts
my best guess about cause is that LFPF is over or under some very narrow target on short time under warmup
sequence caused on that db_HFPF.
ì`m try to pinpoint situations what trig that issue with Trebila but do anyone here have any ideas on it too ?
i have now some 500 km with the car and must say that VTT parts has worked flawless, Trebila tune has been
better than expected.
like i told, that 135 came to me as accident cause first it was men`t for my wife`s winter ride but it show up
to be too dangerous for that usage, so my wife is driving 535Xdrive diesel (tuned.. is there another types left)
and when she left it to me, i supriced what kind of tunable engine this little beemer has yippiaiee for N54.
after half hour on internet watching forums for n54 sky was open to mods and very soon it became a toy to me, started to mod it and here we are ....
for a 365 DD drived trough winter season too i think this is the level what can be explained as reasonable tuned ride.. 26-27 psi e85..

compared to stock, yes, they are laggier, maybe 500 rpm or so but on these power levels i describe it
more like "softer power delivery" cause stock boost levels is arcieved at some 2000 rpm and full boos at some 3300 depending on gear and load .
on levels of 700whp that little longer boost buildup is doing the engine easier to control and on my opinion it hits that sweetspot to at6 tranny (xhp stage 3) normal cruising on D it roll at 1400-2000 and pushed from there on 6th it build boost
but not as much as stockers, little more pedal and you are in 5th with 2000-2500 and some more pull than stockers. on sport
it`s on over 2500 and there start to be serious pull all the time.

And when you are for example at 4000 and higher is power instant? Or at how much rpm is it? I'm MT so when I downshift to e.g. 4000 and floor it, will be acceleration instant? Thanks
from 4000 rpm, if floored it can be called instant, maybe like stockers at 3000.
there has been shitty weather here now for 5 weeks in a row, raining snow or water every single day so no
test runs with high boost or anything. it`s very annoying to wait for even one dry day to get few logs just to know the car perform like i want it to but forecast throw here for sure wet snow raining for 3-4 days.
for next summer there is to come hoosier dr2`s to rear and attack for high 10`s / low 11`s with 130--> mph
and 186 mph 1 mile barrier starts from there. maybe carbon hood, or some other weight reductions..
i don`t get this reasonable lightened to under 3000 lbs but quite close and that should be enough for
my goals because i want to keep it stock like sleeper.
