Aye thought so, looks pretty much identical to my torque graph.

to be honest it depends what you want to use it for, id want the lower power car if it was an every day car, then the higher power car for track or fun driving when you need to rev it for it to get anywhere.

Bolting on bits doesn't make it faster. It will all need remapping to gain the full potential.

adam, when you on track you learn to drive to the best potential of the engine, so if it meakes peak power at 6,000 rpm you keep the revs up there.

steve, i used to dive my corsa like that daily and robin gave it some shit too......

Thankyou

Thats what i'd doing with Monster's engine, bolting everything on, fitting it all. then sticking it on a trailer and getting Mr Vsport to remap it for the track.

To me, it just makes sence.

pauls got a point but it soon spirals out of control, may as well get stand alone management on there with the cams, make a big difference then

Cams and balancing plus the 4.18FD into the F13. I don't know if i'm going to go for stand alone though.

You'll regret it if you don't Steve, the car will never perform to it's full potential on standard management, even when remapped.

How much? And how much difference will it be round a track?

I've been saying this for ages

A 1.6 16v with 150bhp will still get beaten by a 2.0 16v with 150bhp in most cases.

Round a track? The weight difference is just far too much.

supplied fitted and mapped from 850+vat if he is pricing it the same as us. we did a 1.4 16v with bdlis inlet a while ago with gotech, was nice to drive afterwards

with aftermarket management you always get the full potential of everything available from your engine, also gotech will run full sequential injection if you keep the cam sensor.

give dave or me a call to discuss the options, its hard to explain over the interweb

I understand what you mean. Cheers. I'll be getting the pullies that work with the standard managment. So will help that way.

Whilst on the topic
I converted a few RR graphs(when i was bored at work

) into excel format(using some printouts off here, and some of my own)
So its easier to compare them.
And as you can see, the mantzel, and copy inlet are VERY similar it terms of peak power, and over the complete rev range.
It also shows why fitting dbilas tb's with std ecu/rev limit is completely POINTLESS(apart from the noise), they loose power throughout the rev range apart from the final peak.
The light blue line is my own engine now
Mantzel-From Steves graph
Dbilas inlet-From the graph Dave posted
Dbilas tb's-Warren G's graph
Std(exhaust/filter)-My engine last year

Going by peak figures, the TB'd engine is quicker, but it wont actually be, on the road

So from 3500 to 5500 the standard inlet produces more power

Quite possibly? That was my engine last year, with a full 2" system, and a de-cat. Standard bar that.
Or that may be my dodgy graph reading :lol
But between those sort of revs is where the standard engines power and torque peaks.

But the std engine produces much less torque at low revs

This is the link to my 125.2 graph on it's own with the torque at the bottom.

Nice and flat.
