Unless one of them changes their fuel pump looks like theyll all end up about the same!

Just a very quick rough n ready calc on fuel.

 

Size of injector x amount of injector

-----------------------------------

6 (cc per bhp)

 

440 x 4 = 1760 ÷ 6 = 293.333 poential bhp.

 

Then x by duty cycle, average is 85% so 0.85. 249.33 potential bhp.

 

You can increase fuel pressure to give more flow, i can do re calcs for that.

But thats a close potential for working on.

 

Id like to see the dyno graph if you can post it.

Stop encouraging them Stuart, you'll make somebody blow one up. Even I was getting excited about it yesterday, looked about three times to see who had the best guess.

[DeanRudkin]

Weve sorted the fuel pump situation so hopefully matt should make more

[tractor]

wot have you done to solve the problem then

[DeanRudkin]

If you run the bosh pinto efi one in line it should do the trick

[tractor]

so your upping the pressure by adding the pinto fuel pump

so basically the land rover pump can handle the volume but not the pressure

[DeanRudkin]

Yeah it seemes that way Im also going to run a new fuel line just incase my old one is to old it only had issues on full chat at about 5500 rpm hence why he had to leave it at the boost its at now

[tractor]

wot fuel lines do you have copper braided or just rubber

[DeanRudkin]

Braided

[tractor]

and wot psi does the pinto pump run at

[Guest lotusPaul]

So when your fueling is sorted, what psi are you expecting? And what were you getting prior?

Im assuming you were a bit lean at the top end.

[DeanRudkin]

I dont know what Im hoping for I never set a figure I might take the car for a spin before remap and see how it feels

[Guest lotusPaul]

I only ask because my calcs were based an AFR of 13. A cruise mode so to speak. Some ecu maps will give a richer mix under boost. I looked into this for you.

With all things being equal in the calcs that predict 233, increasing to the limit of 440cc injectors at an 85% duty gives fuel flow to support...300bhp.The magic 14.7 drops the power to 205bhp.

At the richer mixes your in danger of washing oil from the bores.

I know maths is maths but its how it drives that counts. Unless your leaning out at you current boost then why push for more.

[DeanRudkin]

Ive got to drive it first to see how it feels then I may go for more power
