5 GT Turbo F4Rt - hopefully the correct decision

[Mark Davis]

Mapping booked for 8th April. Gives me a date to work towards and plenty of time to get everything fully tested and squared away.

Ticked off a few wiring jobs today.

1. Alternator wiring permanently fixed to resolve the running on issue.
2. Bosch 044 pump wired in with relay etc.
3. New starter motor wire
4. Racelogic box fixed in permanently (just needs tidying up)

Just waiting on custom fuel pump bracket to finish fuel system, it should arrive Monday. I then need to set gear linkage up and ready to do some miles.

good stuff time for some miles then a mapping sesh

A mixture of excitement and apprehension. I’ll be more excited and confident once I’ve done a few miles and ironed out any little issues.

Custom bracket arrived today for 044 pump, it’s spaced 4” so it can sit neatly next to the outlet from the swirl pot itself. I just need to secure in place and then run a few fuel hoses so should be good to go for a few miles this weekend.

My only concern is the 044 outlet to engine sits too close to the back box so I may need to move it all over a few inches for to gain a bit more clearance. Not sure how toasty the back box will get.

That’s the fuel system sorted.



Next up sorting a better oil breather set up.

 

[Brigsy]

Getting there any pics of the finished fuel system?

Regarding breather system, i have been looking at modifying or making a similar setup to a cossie oil seperator/breather system. You could take the oil level sensor out of the sump and use that for a breather. Might be overkill on a fresh engine as they are usually pretty good with just a cam cover breather but may be worth a look.

Will get some pics tomorrow of setup. My only concern and one I need to check is that there won’t be any pinching as I’ve ran hoses over torsion bar. Will check on weekend.

Not sure regarding breather set up and I know @James5 and a few others running just the one standard breather but noticed that many high powered turbo cars run dual breathers. A lot of the Honda boys do it also plus Scoff and Robbie have done the same so I was planning on adding a second outlet/ port then into a dual catch tank. A bit like this.

 

[Brigsy]

Worth adding the extra breather, easy enough to do on the plate. As far as i know Scoff has added a crankcase breather into the sump too but hes really starting to push it now, so prob overkill for most setups.

I can’t believe Chris is at 1000hp, pretty amazing. Hope he runs the car this year, can’t wait to see what it does.

I know you’re all bored of these stationary vids, the next ones will be me actually driving the car (I promise)

Anyhow a mate Lee was kind enough to take a good look at the map for me today, he spent a good hour tinkering with all of the fuelling and general settings in Wari, starts on the button now and idles at a much safer 14 odd rather than mid to low 10s.

Had some issues with coolant temp rising really fast and the fan wasn’t controlling the temps at all, saw 100c at one point. Anyway long story short I needed to recalibrate the coolant sensor with the info Chris at EFI provided a few months back and bleed system properly, that’s all sorted now.

One downside though is the running on issue still exists albeit intermittently. Need to revisit this as when it happens only way to stop car is to pull ignition coil pack plug.

So sort gear linkage, go for a drive and pray it doesn’t end in tears. Wish me luck

Oh and the shitty release fork, release bearing or input shaft noise deeply upsets me. When clutch is depressed it’s purring!!

ECP are doing a 50% off so ordered a new Lucas 110a alternator. @Adey the freebie alternator you gave me, did you ever use it ?

 

[Adey]

im sure it was a working one off my car before swapping to the cup setup. does it have a manufactured sticker on it?

Yes it’s a Valeo unit but looks to be remanufactured by Bosch but no date.

 

[andybond]

@Mark Davis have you got one of our stickers?

@Mark Davis have you got one of our stickers?

I thought I did but i haven’t got one on the car by the looks of it. Happy to whack one on if you have any lying around?

Oh well, for peace of mind I’ll whack a new one on, everything else is new so why not. If issue still exists after that I’ll have to fuck with the wiring again.
