Top RB20 Club... do you have over 260rwkw?

[quincy777]

Hi Guys,

Got my car back with results.

GT3071

Apexi PFC

Apexi FMIC

full exhaust

cold air intake and shield

GTR injectors

040 fuel pump

254.6 RWKW on 22psi

all on standard internals, so hoping it lasts a little while at least as it is heaps of fun..

[Cubes]

Well.. Where's the dyno sheet.

[Roy]

Very interested to see the plot. Same tuner and dyno...about the same power at the same boost...will be interesting to see the difference is repsonse...im guessing yours must come on a little soon then mine.

You must be stoked...car is a completely different animal once you get some boost in them

[SimonR32]

wooooooooo

ppl r starting to make some serious power

time to turn my boost up

ill be getting another tune beefore the wa 4,6 and rotors in october so i will post results when i get it done

[Rolls]

How long would an engine last on that sort of power providing the tune isnt too bad and its not pinging/overheating?

Say if you were reaching 7500 on a regular basis

lots of boost you are running there........

def want to see a dyno sheet.

[quincy777]

Wrapped thats for sure..

I only have paper copy of dyno sheet and don't have a scanner. Any help and I would be more then happy to put up. How do you guys normally post it as file?

got a digi cam?

take a pic and resize.

[quincy777]

Best I can do for now,

Max power is at 8250RPM LOL.

cheers..

[B-Man]

Nice

ok just if anyone is interested in doing the internals on there rb20, mine cost me 2.5k just on machining, no parts like arp rod bolts, forgies, cams, etc.

[Roy]

2.5K for machining? I take it that involved head work etc, or at least shaping the combustion chamber for oversized pistons, or clearing the block for a crank with a longer throw.

That dyno plot suggests to me that thing would be a great setup with a smaller exhaust housing. You are running a 0.87 , correct?

Whats the next commonly available housing size down, is there a 0.73 etc. Someone told me the 3071 runs a pretty big turbine, so dont be too scared of going down a size in housings. Also what manifold are you running, and what sized gate?

Running.64 housing. Turbo is low mount version, sitting on standard manifold. The gate is the crappy one with turbo.

Cannot control the boost to be any lower then 22psi. (any suggestions)

3071 is a big turbine wheel - seems good so far other then boost issue.

How does it compare to your graph Roy - as this turbo was a gamble against your great set up.

[boostn32]

thats for porting, cc'd chamber, 3 angle valve job, new guides, seals.

drill bearings, chem/acid wash block, boring, honing, decking, beam polishing rods, and other stuff. it looks like my TD06-20G will be to small, so turbo and manifold may be for sale soon.

[bj_dove]

what would be a suggestion as a step down from the 3071 that can be mounted on the standard manifold??

[HRthirtyone]

i rekon .64 housing should probably see 1 bar around 4-4.5k rpm, not so laggy that its stupid.

[Rolls]

What rpm does it see max boost at?

I'd look into some cams... guy here stateside just put down 386 rwhp (~288rwkw) on a 30R with similar mods plus cams, gears, and intake mani... I would imagine that power level is attainable with the 3071 as well. What RPM is that where you are hitting 15psi? With full exhaust... do you have a converter in there too?

Nice setup by the way!

Max power at 8250rpm!! Holy crap, my 20 has never seen anywhere near that in two years.

Max power is made at just over 6,000rpm on mine and rev limiter is set to 7,000rpm.

If you are making peak power at 8250rpm where did you set your rev limit to?

[quincy777]

8250rpm holy crap was my first thought also.. Not going there very often but seems to happily scream all the way there. Rev limiter not sure about.. Running full titanium 3 1/4 inch from turbo with high flow cat.

getting 1 bar at 4200 RPM so it's pretty good.

If I could afford cams I prob would, but having fun trying not to skid in the dry at high RPM on 255's.
