Only really worth comparing on the same engine TBH

..  on the same dyno on the same day. There is enough variation between dynos that you can't be sure you've made a gain otherwise.

However, looking at that dyno plot, it clearly doesn't exhibit the almost flat torque curve from 3,000 - 5,000 RPM that the standard engine does. Yes, the "pub figure" at the red line might appear impressive, but the multiram system is there to improve the spread of torque throughout the rev range.

It wouldn't really matter if it is from the same engine as long as it was running well during the dino just to get a basic figure of what a typical engine is putting out, or more important, where the torque curve is...as I am guessing even if it was slightly down on hp the torque should still be in the same range.

I can't really see the photos on my phone. Someone tell me what they say please

[weasel]

Yeah i didnt really mean figures, just ive never seen the torque curve of a stock x30xe, so would be interesting to see roughly what they look like,
Like i said though, this car was built for drifting, so having all the power higher up is far more useful to me, the power delivery has changed ALOT  since fitting

[mr carl]

I just saved the photos and took a look, that is very impressive is that the only mod you have done?

[weasel]

I dare'nt mention any other mods, because i seem to be in the wrong for interfering with GM's brilliance :p

Haha it is a bit fround up on isn't it, it think the main reason for this is the car tends to attract older people who like to keep things standard.

The fact you have changed a few things does change things for me, because you wouldn't know which mod gave your increase, you could have done one mod that raised your power but the in take could well have brought the power back down

What other things have you done?

Have a read through this, they seem to be doin alot more with it in other contries

[mr carl]

That's because other countries are more curious than us safe brits lol

After reading it, they seem to conclude that the stock setup is the best!

o crap im gonner get grief when i fit air ride and a blower. 8-)

LOL it seems that way.

I would rather have the power higher up in the rev range, its nice having the grunt lower down. But that cool if you are driving around town but a little pants when you get on a motorway or any straight long road.

But I think my multi RAM will be staying there as I don't have the money to get something like that fabricated

When you do make sure you link me to the thread

It all depends what you use the car for, if you are the sort of person that buys a 3 litre omega, and then worries about MPG, i guess you would want to keep it standard, if you use it for drifting, you will want it to have quite a steep power and torque curve to make it easier to break traction, so basically all down to personal opinion?

The latter is more up my street )

Forget multi-ram then.. get yourself the diff from a 2.5 v6 auto from after 1998, and then weld it up....
