if that was @ the wheels then thats really good,what was the flywheel fig ??

NEWTON

that was at the wheels but we couldnt let it run at that

NEWTON

fly wheel fig is on the graph

NEWTON

8.5-1

GARETH T

it you measure it at 8.5:! or you goign off what the pistons was ment to be?

NEWTON

it got measured,using standard comp accurlite forged pistons with machine work to the head

Any idea how they measured RPM?? I just wonder if it's a pick-up discrepancy? Does seem awfully laggy.

NEWTON

god knows mate this maping lark is double dutch to me.but it needs to be sorted,how come the power ends at 5,770 rpm?

pee vee

yeah... why does the power seem to Drop off completely at about 5700
RPM on just about all RS turbo engines ive seen graphs for?


also Why does it make 106 lb/ft at less than 1500 rpm
and yet it makes less than 40 at about 1600 rpm???

not a dig or anything mate. just wondering

good result really for a T3.. apart from the lag issue

crazycage

thats just a spike in the graph, dont no why they always drop off like that

NEWTON

dont no myself mate,but i want more power,i think ill change the cam to a newman spec with solid lifters,and change the turbo,god no;s to what spec tho

SapphyMike

How do you manage that?

NEWTON

id like to know as well???

Garage19

By bolting on a turbo.

My point is why spend all that cash on the CVH when you could get that power from a standard 2ltr zetec with the addition of the right turbo and and some aftermarket management.

NEWTON

it still going to cost more than £100.00 eg management , injectors,mapping ,turbo...it all mounts up

crazycage

i would have your engine mate and not a poxy £100 zetec with god no's what mileage,it would cost just as much to do do a zetec right,i'd like to see a zetec with just a£100 headgasket deal with 22psi

tonyk

It all comes down to what each owner considers value for money. If you add up the cost people spend on these cars it really is scary.

Example:

All Steel Bottom end £2000
big valve cylinder head £500
Stg 3 turbo, T34 turbo etc...£300-£800
Air Filter Kit £60
Exhaust System £250-£400
Tubular Manifold £500-£1000
Management Software £200-£2500
Large Intercooler £300-£500
Decent Gearbox £500+
bigger brake setup £200-£1000
Suspension Kit £300-£800
Fixing Faults with Car, rust, bushes, sensors, etc.. £100-£1000's
Labour For Fittting and mapping £ Dont think about it.

Seems a fair enough graph final figure but it seems it not making full boost very early....for a t3 anyway That explains the tailing off though, you need a bigger turbo mate

NEWTON

thats what i thought

NEWTON

ill have one very soon

Garage19

I'm factoring the management and turbo out of the equasion as you would, and have had to, buy them anyway.

Just sheerly talking about the amount you have spent on the actual engine.

Garage19

So you pick one with a known mileage. Have you ever actually stripped down a 100k zetec?? It will be in much better shape than a 100k CVH.

As for doing it right... why is it not right if it is making the same horsepower for £1900 less? If mapped correctly it will be just as reliable. With the right turbo and due to its extra capacity it doesn't have to deal with 22psi to make the power!

back to the thread......any help in turbo spec and cam spec would be good
