the map doesnt change trans losses??????
who said it did...about 11% loss between both sets of figures....low for a fwd car i know...but hey...both sets of figures on same rollers, same conditions.
the map doesnt change trans losses??????
as above....the mapping CAN make the diff between fly and @ wheels figures. if the first map really is that s**t, and the finished map is all goooood
It's great to see you're making such an effort to get this sorted Matt! Don't know why you seem to be getting so much of a flaming. Hope its sorted easily
err u did there? Unless I'm not understanding what ure saying
You're saying that the difference between fly and wheel is the trans losses, and is completely seperate to the map?
Makes sense to me.
You're going to have a hell of a job setting the timing with a DTI, the cams fall out when you remove the cover...
I'm sure the VVT actuator should click, have you tried measuring it's resistance?
I have to say, I'm very interested to know what is actually going on with this car..
My engine has 422's and no vvt, but I'm sure the cams are specifically non vvt. They also need verniers to time correctly.
As far as I know the 428's should use the oem specs.
Yeah, the more power you have the bigger the losses but the map makes no difference to this flywheel @ the wheel figure wether it be a good or poor map
Havent tried measuring its resistance, but it is drawing current according to our scope. No audible click, will use the steth tomorrow...
They also need verniers to time correctly.
In that case, Danny has timed the enginewith his renault tools to be as per OEM, and we have lost 50bhp... arghhh! lol
Pmsl
That's what I mean. It doesn't make sense!
I'm meaning the 422's need verniers, I think the 428's should be fine on normal pulleys.
Hopefully Cat can shed some light.
Yeah, the more power you have the bigger the losses but the map makes no difference to this flywheel @ the wheel figure wether it be a good or poor map
so a car going in with 250 bhp at the wheels...and coming out at 270 makes no diff to the actual flywheel figures??
i see. the map miraculously just gets rid of transmission losses.??
Im almost certain too that the vvt actuator should click. I'm almost certain as well that if these are 428s they should be timed up as per OEM.
Are they DEFINATELY 428s?
I think you are both making the same point.
As in the ratio won't change. for more power you will have more losses, but it will still be the same scale.
it's not as simple as that, it isn't a straight ratio
only 100 less than KTEC for a conversionMaybe to cheap.
Really? What else is going on there?
I'm actually interested.
That was what they were both trying to say though.
That seems a bit high, would have thought around 175/180 would be about right?
Anyway, Comps look ok, up around 200psi, pretty much even so no valve damage.
