made 400.6hp atrw today on 15 close to 16psi 47deg!!!!!!!

tryed 18psi coils were breaking down.... time for spit fires.....

also was close to running out of fuel up top with a sard intank pump and 720cc sard inj....

so were going to rewire the fuel pump with bigger wires and put in a relay

also thinking about a fuel reg? or should the stock one be fine?

still makes power at 8500rpm stock cams!!

yeah that will be the problem do you have a link for the fI guild mate?

ill also change the fuel filter.... still has enough fuel now, but there was no room for more fuel up top as it was starting to run out....

but dose it pull hard up top end!!!! power never drops off just picks up more and more :thumbsup:

still comes on around 4700 5 but makes up for it up top and the extra revs!

more boost will be crazy!

and down low its still just as nice to drive say 4000rpm under..... tuned helped alot still makes boost at say 3000rpm few psi so its not like a lag no bottom end power car! :P

FI Guide - is the stick topic @ the top of this section... along with the dyno result ones mate :P

Tells you what to do, its fairly straight forward and even i would be confident doing it as the DIY is very good.

I think there is also another DIY thread (in the DIY section) on top of the FI Guide DIY link :thumbsup:

In those kind of ambient temps your fuel temps may well have been over 65 degs on the dyno - which can cause the fuel pump to drop pressure and or flow.

I commonly see this issue on queensland dynos where the room temps are up around 40degs. Its just those bloody southern tuners dont have a clue how much difference ambient temps makes to eninge tuning!!!

I flew to Mt ISA to tune a GTR and i can tell you it is an eye opener....

yeah still in the process

im pulling the emanage out and have got Nistune installed now

things move pretty slow up here didnt you see that lol

are you saying the ambient temps made a huge difference Trent or not alot ???

Ive always thought that they would make an extreme difference to tuning

i did power runs on a differnt dyno it made 285rwkw on 16psi

coil packs are in re wired the pump

with the stock reg it was really rich after the wires were done!

fitted a adj fuel reg

turned it back a bit and added some more boost 17 psi same dyno as the 285kw run put out 336rwkw

300kw on 13 14psi

still needs a tune and more boost... will be done in a couple of weeks :D

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
