Where the freak is the new dyno graph.

[Madaz]

i posted some graph up but dont seem to see them

[Madaz]

for some reason my post with attachments isnt about maybe its some where but i cant find it here are some pictures

Links taken down board playing up :S

video wont be long

Yep.

Very impressed with the numbers however at the last minute we suspect the exhaust cam is a tooth out as with the stock cams the power came on alot earlier....Will keep you posted with more information

cubes, only specs on the cams i know is 264 duration and .64 something. thats all i can remember offhand..cost a bucket!

here are some pics!

Be interesting to see the results. Im betting the std cams will get it on power sooner, and probably make the same power anyway. Rb20s have pretty big cams std

ok guys here it is enjoy it wasnt heaps loud so i put a sound track on it also

[Turbo Dave]

Would like to hear it without the soundtrack, thats what people were after I think, but it was a good vid anyway..

[Madaz]

really it sounds like a skyline i debated a while about just leaving it but

1 we all know what they sound like

2 you can hear it enough through the music

3 that's my opinion

[esky_mad]

i dont have sound which sucks.

ive got a 3040 on my RB20.

3540..... tits yeah!!!!!

[Madaz]

ok dave here is just the sound track no picture 420kb

>>Michael 297kw Soundtrack<<

EDIT

for those that may want it on there Nokie Phone or MP4 compatible device i have it in a 320x240 format weights in @ 12.7mb oh and i took the soundtrack out

[Ryanrb25]

Yea steve, id love a copy for the nokia.

We're very pleaseed with it so far, haven't finished yet. Still some fine tuning to go. a fair bit more work smoothing out afr's and also ignition timing...but very pleased with 16psi tho...have plans for a little more boost with a little less timing just to experiment.

And

might i add, its a real animal on the road.

Thanks mate

GREAT WORK !! Sleeper and a half !

Did you do any head work at all? Definetly still a 20 right?

[mr_rbman]

mmmmmmmmmmm, i have the exact same turbo on an rb30 twin cam and i only make 254rwkw's @ 14psi!

yep hehe still a 20 dude, head work was really only a clean up. Valve seats and valve stem seals...but nothing performance wise.

mmmmmmmmmmm, i have the exact same turbo on an rb30 twin cam and i only make 254rwkw's @ 14psi!

hehe yea as i said, the 20 only made 250oddrwkw on 20psi before the cams...quite impressed with the way the cams turned out. Alot of money tho but the cams also eliminated a few dips higher in the power curve. We suspect was due to airflow. They disappeared straight away.

more to come in the way of earlier power delivery..

thanks for your comments guys, this was merely just a test car for us to learn how to tune. Big reps to the Microtech and the pc interface.

Wasn't 250rwkw odd made with ~12psi once you done the cams and port matched the turbine housing + on a 35+degree day?

Once you push 15-16psi in to yours it should be up around 280rwkw.

Then the usual 18-19psi and 300rwkw which is the norm for an rb25det, rb30det with std exhaust manifold.

Swap out the std exhaust manifold and you could make 350-360rwkw without too many drama's.

But yeah.. it doesn't really sound all that angry in the vid + 16psi for 300rwkw with an xr6t turbo on an rb20 with cams does to my self sound a bee's dick high especially with a std exhaust manifold; but I try not to care.

It would be interesting to see how much more is in it on that dyno as the std exhaust manifold on boostworx dyno really struggles once you push 290rwkw. Increasing boost nets small power increases and tops out around 300-310rwkw absolute max. Regardless if it has cams, big turbo's or what not.
