First tune:

Very much identical to SKY30 in everyway,
except for extractors and external gate,252 duration cams and adjustable cam gears, made 470rwhp on 15psi on pump fuel run in tune,

Second tune:
602bhp or 450rwkw on 29psi pump tollulene mix.
Replacing clutch atm ,as it shat itself on the second and third run.

449.7rwkw/602bhp chart

Just got my car dynoed this past week. Car feels great til about 5900rpm then starts to valve float. It made 228rwkw's@15psi. This is in a 1992 R32 gtst. I rebuilt the rb30 to na spec and the head is from an r32 with an rb25de, i just had that checked and the seat tension re done, should've put GTR valve springs in when i had the head off!

Mods are:
full 3" stainless steel exhaust (custom dump pipe)
600x300x75 intercooler with 2.5" piping
Apexi Ap engineering Power FC
GT35/40 1.06 exhaust housing
gtr fuel pump
gtr injectors
z32 afm
standard airbox with apexi panel filter and CAI

here's my dyno sheet (the afr's were good with 11.9 - 12.0 all through the rev range!)

That setup on 18psi made 240rwkw. Dont know torque figure. That was base tune for run in. Will be going back for full tune when soon to be items go on. Was tuned at Charlies Motors in Brisbane. They dont give dyno print outs and they dont believe in pimple faced horsepower, hence why our power figure is alot lower then everyone elses for amount of mods done. But it sure is a hell of alot quicker then old rb25, I can swear by that.

Ill try and get a printout on next tune, if not ill just have to take a photo if im there whilst its on the dyno. Were hoping for 300rwkw

Anyway here is the dyno graph from the tune. They had problems with wheel spin, they couldnt keep the car down, with it strapped down as hard as they could get it and with a few fellas in the boot it still managed to wheelspin...They chewed up the re55 sr's...made a mess of their dyno room. You can see the blips on the plot.



So final figure was 320kw at 8000rpm, wanted to keep going but 8k redline is fine. That was on 1.3 bar(19psi), knock is around 50-70. So due to boost spiking and excessive knock, that was the highest boost we could run with. Next step is definetely the water/meth injection, bigger cams and probably the 1.06 rear depending on lag difference. 400kw would be great, and shouldnt be too hard to achieve with the future mods.

Things that we changed to since last tune : 110mm ARE intercooler, turbosmart 48mm WG, 6boost manifold and ATI damper.

We are happy with it so far, and will know how much better it is in a few weeks at sprints and racing at QR

*New power output with water/meth injection is now 365kw @ 8000rpm*

I'm posting for:

FOOLBOOST's RB30DET

Motor:
Standard fresh RB30E
R32 RB25DE untouched standard head (valve springs, cams etc)
1.5mm Cometic Headgasket ~7.8:1 static comp ratio

Inlet:
Aftermarket Plenum
Sard 800cc Twin Sprays
FMIC

Hotside:
Standard Exhaust Manifold
GT35R .82
Tial Wastegate
Bleed Valve
Am-Performance Ext Wastegate adaptor/spacer
AM-Performance Dump/Front pipe
2 3/4" Cat Back

270rwkw @ ~6200rpm and power holding well until 7000rpm.

The highest we saw was 280 something rwkw but it was floating quite badly.
settled on 270rwkw with what I think was still 'some' signs of ever so slight float

The second attached dyno sheet is a before/after fitting up a plenum without touching the ign timing only resetting afr's back to 12:1.
Prior boost was hitting 9 point something psi then tailing to 8psi, after the plenum it held a solid 8psi and appears to have lost a touch of mid range, this could be due to slightly less boost and the lack of fiddling with ign timing.
None the less power has shifted up the curve rather nicely which is what we want out of the rb30 as to get some speed in any gear. No point it feeling like a diesel.

1bar saw power touch 265rwkw. Gains after that were minimal due to soft valve springs.

MORE BOOST!
