Hi @TRD2000 I see in an earlier post that you have an E11V2 ECU.
I just bought one so need a base map to start with. Would you be able to PM me your map?
Thanks

it usually works out pretty close to power=torque x rpm / 10,000

so if your making like 350nm at 4000 rpm should be round 140kw
or 350nm @ 8000rpm=280kw
at 4000rpm (120kph depending on tires & speedo) you're making 170kw on 20psi .... which should be your peak torque too.

i'm guessing you make peak torque of around 420Nm.
if your torque stays flat that should mean round 255Nm at 6000RPM (170kph) which is about where you're at, then the torque usually starts to fall off as the turbo runs out or the head/cam/etc. becomes too restrictive.... the revs go up but the torque falls and power kind of flat lines....which is what you're seeing.

shame i can't get my graph to show, I'm only running 14psi, but round 6100rpm, where the torque starts dropping we ramped the boost to 20psi at redline to keep the torque flat.... consequently my power keeps going up.

it's kind of cheating, and it means i hit redline a lot, well that and jumping off the bike which screams to about 16,000rpm, sometimes i just forget to change ;-)

not giving you a lesson Dyl as i'm sure you, and many others, know all this, but figured a bit of an explanation might be helpful to people befuddled by their first dyno chart or working out how to read it and work out where to go next.

the fact that you're managing to hold 20psi till the end of the chart shows the turbos still got legs at that poist for that pressure, wheras a CT26 would have maxed and couldn't flow enough to keep boost up, and a gt3071 would probably have peaked also and be on the way down..... if your boost is holding, but your torque drops then you're either not getting enough air or fuel. If your boost drops then you need to do something about the turbo.... or just accept that you're not going to get more power up top and not bother with mods aimed at the high rev range.

Can't remember the Nm that its making... the dyno number for torque are always all over the place...

hmmmm for some reason i can't get my dyno graph to show.

however!... out of interest how many torques are you making? looks pretty flat by the boost (mines flat while boosts flat but im only at 14psi

Nice chart!! Dont forget the dyno would be actual KM/h (not speedo) so when checking use a GPS for better accuracy.

the gen3 came with different ratios to the gen2. When I get my car back i'll have to test it out again.

fung9420

just realise someone has the same combination as me.... SW20 + 600RR...

Thats because they are both fun weapons in their own right!
I shall soon be joining the CBR600 team, up from CBR250 " />

anyway...
I have roughly calculated for my Gen2 turbo in 4th gear that:
70 km/h = 2250 RPM
90 km/h = 3000 RPM

dunno if gen3 is any different? also wheels and tyres can affect this.

Pity that graph is in kph rather than rpm.

anyone know the ratios in 4th gear to work it out approximately?

IRRC 100km/h is about 3k rpm in 4th... i can never quite remember.

There's my dyno with boost graph. I have the twin scroll gt3076r which is a 0.76 housing size, but should still give a good indication of how it should spool up.

a set of Tein coilovers...
and a MOMO steering wheel ...the only thing actually i can see the whole time i drive my TWO....

just realise someone has the same combination as me.... SW20 + 600RR...

SO... will soon have some KW V3's in it (thanks Dylmrt)
and probably some whiteline swaybars.

check out dylmrt's showroom thread, he has a GT3076R. I'd say you would expect peak boost around 4,250. in regards to Haltech, why dont you save the current tune and then saveas a new file and fool around with the settings?

RE: hi all. (TRD2000)

OK, so i was mucking round with the haltech software on my laptop last night. I have a theory about my boost settings and i'm going to have to plug into my computer and download the tune info to find out if i'm right...... last time we did that it completely wiped my tune from the haltech's memory so i'm a little nervous.....

i think my boost controller's duty cycle is too conservative, i think if it was made a bit more aggressive i might get boost a little sooner, cause it's pretty slow coming on... i think this may have been what my mechanic was talking about when he said he'd made it a bit soft in the low/mid...has anyone played with this? does anyone have an opinion about when a 3076 should be making boost with a .82 or .63 A/R housing?

about the only pic i could find... first run in tassie with old 150rwkw CT26. tune. Top of the sideling (targa stage) and the brakes had a few issues... i thought my engine bay caught fire cause there was smoke comeing out the vents so i pulled up.
