You clearly know the game and are prepared to put the time and effort it.... I for one will be watching this space to see the results and how it compares to the likes of moontune (I love this new name) and other bolt on packages.

Best of luck and keep posting progress

yeah.. my mantra is: tuning is a balance of what is achievable and what is usable..

i.e having a 300bhp race engine that only makes power between 6000rpm and 7500rpm is pointless on the road. it will be unusable.

Hurrah - another person who understands its not just about max power!

Moontune is usable me understands too.

steve, how much is stage 1 mountune and how much is it fitted?

Personally I think the 185 mountune kit does reduce the drivability becuase you lose low down torque.

Me too - I'm sure on a track the car would be great but I'd rather have low down torque too.

But in the current weather less low down torque is a good thing as it'll mean less wheel spinning in low grip conditions...

I have seen a nice rr graph on the dreamscience website for the puma build 190bhp kit.

tbh it is the best looking graph i have seen and they have clearly done some work on the mapping side but there is still a nasty hole from 2400 to 3000rpm which i suspect is a mapping issue..



The only thing that determines how fast a car will be is the area under the graph. From this dyno plot we can see that there have been gains in both areas for bhp but most importantly torque.. :-)

This is what i am aiming for.. just more of.. lol..

Rich have you seen the mountune graphs, just for comment see what you think:-

seems to be drop of a mountain side with the torqe too !

Lb/ft --> Nm = x ~1.36 if my maths is up to anything

Not sure I agree with the area under the curve comment; this would not take into accont 'peaky' power delivery

Steve,

The term 'area under the curve' is specifically used to look at the torque measurement on an engine to compare 2 cars that are both geared to use their respective rpm ranges, the one that makes more torque, makes a lot more power, and thus, all else equal, will be much much quicker.

f you have two hypothetical cars, and one makes an average of 200 ft-lb of torque from 2000 rpm to 4000 rpm and other makes 200 ft-lb of torque from 4000 rpm to 6000 rpm then clearly the second car will be quicker as it has a greater 'area under the curve'.

Steve,

The drop off is due to the run being shut down..

They just shut the second run down earlier..

I just want to clarify that my statement 'best graph' was referring to a comparison between the standard power run and the modified one.

Pink Rinse sent me his power graph to have a look at and this is a much smoother curve and shows that his mapping is most probably better.. I don;t know what mods he has mind..
