how does my graph look?

just posting up my power run to see what you guys think

Looks ok, what management you using? That AFR curve is all over the place.

 

[GTdan]

bit too lean at 5500, would like it closer to low 12s the higher the rpm you go.

 

[Rev]

Looks fun to drive,Torque is doing very well after 3000 rpm what turbo do you have ?

 

[GP82]

Yes thats looks like a fun car to drive, very useable powerband and really good boost control.

Which turbo are you using ? Looks like a hybrid of some sort?

 

[baconfrys]

CT9 Hybrid turbo

 

[baconfrys]

what would cause this?

CT9 Hybrid turbo

Any more detail on the turbo it is producing good torque. eg Manufacturer compressor blade type etc ?

I agree that leaning after 5000 is an issue , hopefully just a tuning issue.

 

[baconfrys]

is it something to worry about?

its a cheap and nasty toyo sports hybrid ct9 mate pulls like a train until i broke no 3 piston but getting forged as we speak

should i ask the guy who mapped it to change this slightly?

 

[Rev]

Thanks , I read leaner than 12.4 on boost is a risk , also manifold upgrade or porting is needed to avoid piston no 3 over heating if you haven't already done this.. As said from people who know on this site your map appears too lean up high . That being said the manifold could have made things worse or a blocked injector can cause leaning.

 

[baconfrys]

yeah i did i replaced manifold and down pipe not the best in the world but better than the standard ones but when i upgrade to td04 i will put better quality on, but until this turbo goes bang i am just going to run it

 

[baconfrys]

since this map i have changed to 330 injectors instead of standard and a uprated walbro 255 pump so once re-built should be better after a tweak on dyno

 

[weeJohn]

That looks way to lean for my liking, 12.7 at the torque peak, surely thats way to lean?

 

[GTwayne]

Looks good apart from the afr, which seems a bit errattic.

 

[goldenvtr]

i map my cars for 12afr up tp about 4500 then 11.5 afr till redline, i wouldnt ever want to see over 12.5 on boost!
