392B.H.P.SAFF

the thread isnt about ke-jetronic or upgrading to any efi system,what noisy boy is asking is about bhp and then ib/ft loss,only what we read in the mags

still waiting for someone to bite back at why im still on l8 yet still manage 427 and 443ib/ft on standard cossie management

reality

Bite back about what? I don't see any problem with 427bhp & 443 ft-lb peak on any efi management.. That's down to engine spec, not ecu (assuming it's correctly mapped)..

reality so the ecu has nothing to do with the fueling,injector timing,map etc?
if i build a good spec engine and put a standard ecu in i will still get that sort of power

i give up on this post im sticking to cossie talk much better

noisy boy i understand what you are saying good luck in finding the answer as i dont think a lot of people understand

reality

Note I said "assuming it's correctly mapped".. you're obviously not going to get 427bhp from a 'standard ecu'.. well, not unless you have a stack of nitrous on it

how has he lost torque when he never had that much torque untill gotech was fitted.

as i said b4

quote

if u look at all the big power 1600 they are all makin around 270-290lbft , if u look at the 1900 or 2000 they are makin 330-350 because of the capacity not the management

and reality explained to u here

Hang on.. on a turbo car, the amount of peak torque is generally relative to how much boost (on a particular spec turbo) you run.. the amount of power you make depends on how high you rev it.. power is just a function of torque.. however, power is airflow, so your peak power is limited by how much your engine can flow!

I've seen quite a bit more than that

What, on a rolling road?

Noisy Boy

Guys calm down my point is If i wanted to build a engine not that i wanna do i aim for a engine with more torque then bhp or the other way round, you see my mate has a civic running the vtec system it has 152bhp 112lb/ft and i was running 141bhp 184lb/ft and i would beat him all the time? even rolling starts! Now as for nick from performance ford i never said he lost torque! and yes stu he did gain torque but his torque was less than his power same as yours when you posted a graph where your car shows 309bhp with about 280 odd of torque i think? the thing is, is it the way a car gets set up that the torque becomes less? because he did write that the car was less aggressive then before? not saying its slower or that the ecu is shit cos i dont think it is, but why is the torque less then the bhp? I have no problem with less torque just would like to know why this happens i have always know RS's to have shit loads more torque than power!

reality

It's simple.. the more boost you run, the more torque you produce.. however the more boost you run, the lower your engine will produce peak power (choke -peak airflow).. so eventually your peak power will reach the max but torque will continue to rise lower down the power band..

It's not quite as black as white as that.. but it's a rough idea

just changing the management from KE will unleash power how?

reality

Because the fuel metering unit is a restriction.. it's designed for 130hp!!

I just see a management swap as creating the potential to create more power. If an RST was producing 200 bhp on MFI and the fueling isn't maxed out, a managment change shouldn't release any more power unless the car was badly set up to start with.
