opinions on dyno graph

[Jurgen-Jm-Imports]

i know we have some good graph interpreters here on the forum

 

 

what do you think of the red line, this is a modded Greddy turbo vs BROWN LINE the old un modded greddy turbo..

 

of course my car will be strokered and have head work..

 

 

does this red line look driveable ? also i will rev to 8000rpm

 

 

look forward to your input

the only difference from red to black is

 

a) Full head work with JUN 264 cams

 

b) SPE Hybrid turbo chargers

 

 

but with my car it will be also stroker

The red line looks a comparison to the brown line, not black.

 

I would say red and brown are HP comparison, whereas black and blue are torque comparison.

yes brown vs red

The difference is HUGE. You are gaining spool and WADS of power. Looks like the revs have been increased also though, between the 2 setups. The cams still have the power climing so 8krpm will be even higher. Looking at it though, it makes it look as if it's the cams and higher rev range giving the extra oomph up top with the turbo modification making sure you don't lose anything down the rev range.

 

The drivability looks the same between both setups, no nasty spikes or anything at mid range RPM. Will be a very impressive setup. The stroker will probably make it a bit pokier down low though, so a little driveability will probably be lost between the above setups and yours.

so am i right in thinking if i modify my greddy turbos with my stoker being in place my low down pick up and spool will be better than above graph ?

Yup. If you can keep traction

am hoping an os giken rear diff will do the job

That is a nice curve. I would start to increasing the boost from 4700 so the power climb stays more linear and the torque drop flattens out. That would be relentless on the road and very driveable.

thanks for the input, i have decided to go for the modded turbos so they are going to spe for rework
