I do like this latest modifications

The Underdog

Thanks paul

PaulinhoT

Can I ask, before you cut the bonnet, did you use a drill to make a pilot hole, and then use a jigsaw ?

Plus have you run the car yet, and if so can you feel the heat coming out of the new venting area, cheers

The Underdog

Yes I drilled both corners. He heat at standstill floods out but I'm going to do a video of tuft test soon.

PaulinhoT

That's good, as I've been looking at having my exhaust manifold coated by Zircotec, but can't work out if I could have the heat shield mounts ground off smooth enough, so this idea may work better for me Cheers Steve

Good luck at Combe mate.
Shame I'm away riding
Next year fingers crossed

The Underdog

Cheers rog.

The bonnet vent didn't work out too well when I done string tuft test. No matter what I tried it was sucking air in not out. So it's been replaced with a new bonnet.

PaulinhoT

Interesting Steve, do you think an intake under the front of the car directed upwards towards the manifold would push the air out of the top?

The Underdog

Really it needs to be fully ducted from rad exit to bonnet.

The Underdog

so iv had months of doing nothing on the car now its back to fitting new mods for 2017.

The Black Count

Hi
A couple of months ago I also purchased some gsxr 750 throttle bodies with the intention of fitting them to a standard 2.0 zetec so will be very interested in your experience getting them to work

Cheers

Hello Underdog! Im rather new to this site, but I have been a long time thread stalker on here.

I got an st 170 last year as a track car, and you have greatly inspired me. I find your workmanship and skills highly interesting, educational and very inspiring.

I have read through your build thread a good few times and watched all your video's.

Just wanted to say thank you for posting all your content for poor and amatuer diyers such as myself with less knowledge and skill :P.

Also I am very glad you are still modifying your 170 and I cant wait to see how your throttle body route goes

Keep on underdoggin!!

PaulinhoT

Interesting update Steve (it popped up on my YouTube feed this morning), I will take note on how this update goes especially the noise it makes

The Underdog

i will keep things updated. thanks

thank you very much. glad your enjoying it and its great to know its helping you out. cheers



thanks paul. getting closer to giving it a first start. probably about an hours worth of work before i start hooking the laptop up to the ecu. then my headaches will start.

its nice to see you working on it as all I do is rip 170s apart thesedays

The Underdog

iv spent 4 yrs ripping this one apart. wife says iv ruined a good car lol

Welsh_Bugs

About time you started doing something with it Steve. I got bored of the fiesta to and I've started on my focus now lol.
Couldn't buy my focus parts back could I? lol.

Welsh_Bugs

Steve what spring rate and lenght you using on the rear now? the ones I've got on the focus even at 60mm from stock height are far too high (still looks factory height lol) with no weight in the back.

The Underdog

if they look stock at -60mm then someothing cant be right. im running 10kg rears. what make are you using?

Welsh_Bugs

There just cheap Gmax springs Steve, don't lower to well anyway and now the rears stripped the cars just gone back up in the air lol. You wouldn't happen to remember the dimensions of the springs would you?

The Underdog

think they were 180mm long but on adjustable platform. stop buying cheapy g max and get some decent stuff

Welsh_Bugs

I'm gonna have to work out the length of them without a platform then as she's going in Clubman class and I'm not allowed adjustable suspension. Lol they were on hand from two focus ago, I need to stop building cars then stripping and selling them lol. This time I'm stealing as much off the fiesta as I can then selling the left overs.

One thing I had left over from the other focus you couldn't have was the powerflex bushes, so they have come in handy now lol.

The Underdog

PaulinhoT

I never realized how much goes into fitting these, top video Steve, and hopefully you will get more subscribers to your YouTube channel

Keep up the good work

5hane

awesome work here ! looking forward to hearing it start up !

PaulinhoT

Hopefully we will get to hear this soon

The Underdog

it got mapped monday. it made 190bhp. 174ftlb. but some issues have been found since so its going elswhere to get mapped again. long story. will update when its all sorted.

Thats not too bad i would guess there is more to be had as the omex conversions do over 200bhp on a black top.

The Black Count

I have had a change of plan and bought some bike carbs but would still be interested in your experiences, hope it all works out.

The Underdog

a blacktop would need a fair few mods on top to hit 200. I have 2 mates with black tops on jenvey and emerald ecu and they are making around 165bhp.

Power wise I'm near the limit on a standard engine bit map need smoothing out.

PaulinhoT

If you could think back Steve to how the car went before the modifications, how different do you think it actually feels and goes ?

The Underdog

at the moment it runs like crap. iv got misfires and almost impossible to cold start. it will be sorted soon but its been a bit of a pain of relying on the wrong people to get it done.

jonfoc

Nice result. I wonder what you'll get with a decent map? What sort of total cost are you looking at for this conversion if you don't mind me asking?

The Underdog

thanks. all in without mapping cost just under 1k. thats ecu,loom,throttle bodies,filter, trumpets, backplate. silicone hoses. fuel rail and fuel return and pump sender unit.

jonfoc

Bloody hell thats not bad. I've got a zero mile ST170 lump doing nothing. I'm half tempted to buy a dead St and bang it in.

The Underdog

the ecu is the big money saver. i was looking into a dta s60 ecu and that was 1200 just for ecu and loom. the me221 is the cheapest ecu i know of that will run vvt.

pyle

The exhaust cam is a bit low on lift, so you could buy a stage 1 exhaust from cat cams with the same duration but 1mm more lift. What is the timing on the VVT?

The Underdog

thanks but i wouldnt put any money into cams if im honest. id turbo it before putting anymore cash at NA.

pyle

Turbo FWD track car never works!.. You'll be as fast as a slightly modified N/A engine.

jonfoc

Complete bollocks!!
