Project Q-Felicia

[TeflonTom]

i think i may need my head testing for even contemplating such a rediculous 'money pit' project but...............






who out there know's what this is for eh??

[WW_VRS]

hehehe - I have this feeling you're right somehow there - should be very interesting I'd imagine though

i've been a busy boy this week(apart from being at work )

here's the loom, it's basically a cut 'n' shut on the oe loom, with certain sensors re-located to different positions, and a couple of sensors removed completely. this was a painstaking job which requires a fair bit of skill (and head scratching ) plus access to wiring diagrams etc



A: 36pin Main ECU plug from emerald m3dk
B: Link to dashboard loom/fusebox
C: Ignition Amplifier/Coil
D: Coolant Sensor
E: Lambda Probe Connection
F: Hall Sensor
G: Injector 4
H: Injector 3
I: Injector 2
J: Injector 1
K: 3x bare wires for throttle position sensor
L: Oil Pressure Switch


if anybody else is doing a similar installation and needs a loom made up for the purpose then let me know, if i'm in a good mood i may do it for you (if you join freedom!!!)

Er,, What's a throtttle body?

quite a lot of people are 'scared' of fuel injected engines when it comes to modifications and the like, but they are far easier to get right than dirty old carbs, picking the right jet sizes is a fine art best left to people with lots of patience

hi folks,
todays trip to the scrapyard(or 2 ) has been quite fruitfull

a neglected looking 1000cc mk4 polo has given up it's fuel rail in the name of motorsport and it was only a tenner



it took me ages to clean it thouroughly but it's come up like new now.... believe it or not these cost about £180 new, which imho is disgusting for a piece of plastic

[WoodieGuthrie]

Excellent work sir!

that'll give a lovely roar, and a well set up management system will get you the best from it.

As for the loom-looks almose OE!



Any plans for TB's on Woodie will have to wait until I get the join between downpipe and the rest of the exhaust re joined

is 'was' an oem loom... but i stipped it back to the bare wires and removed all the unecessary sensors and added a few..... twas not a five minute job...... i hope it works

I gahterd that, meant that it looks like you just took it out the car

what's going on?

Instead of having one single air intake point on the car, that then distributes to each cylinder via the intake manifold he is installing individual air intakes for each cylinder.

this allows him to control preciely the volume of air each cylinder recieves, ergo making the engine better balanced and more responsive

[TeflonTom]

there's two main reasons it produces more power with multiple intakes

1) the fuel air mixture presentation to each cylinder is more equalized, this can be really bad on some plenum fed engines

2)the is less flow restriction

You making trumpets for them? if so, what length?

[TeflonTom]

i am going to put trumpets on there but i dont know what length yet, i havn't actually ordered the throttle bodies yet so i'm not sure what length i'm going for yet. i going to aim for around 450mm total intake length(including the trumpet/body/manifold/port) to start with and see how it goes when she's running on the dyno... i may add or take away length from the trumpets to fine tune the torque curve once it's up and running

Thanks!

Thats sounds like a good plan - it also sounds bloody complicated!

Goodluck with the work
