hi guys,

im in need of some help and advice....
im wanting to purchase and fit a adjustable fuel preasure regulator with gauge to my 944 turbo to help with tuning the engine in may, but I’m unsure of which and what kit I will need ie fixtures and fitting to make it simple as poss for my engine?

Im not wanting to buy any of the cheap items from eBay as I wont risk the cheaper gaskets inside Failing, I have my eye on the AEM universal item o ly becuase it’s not fortunes and it’s a make I know , but I’m open to any advice on others ect.

The most annoying thing for me is I’m not sure what fixtures I am going to need and how it should route to my existing standard setup. Will I need to remove and renew my standard fuel lines from the arch well or is it simpler than that?

Any help advice/ pics will really help if anyone can give some id really appreciate it!

these are the two I was looking at ??

Are the sytec a good or cheap make ? Looks decently engineered but never heard of them.

thankyou
Daniel??
 
Hi Dan

I've tried to find out which AFPR I have but failed, I may have bought it from a company who makes these things in Staines NW London. Back when I first started there were but a handful of manufacturers in the UK, the one in Staines was well known in other car circles at the time. They first made me one to fit the rail and then I went the 'universal' route, I think, both from the same company?

Anyway, here's a picture of my set-up, alas, there's no label on the unit to help identify it...

That's it, FSE... it was the in word back then and here's where I got mine from... https://www.glencoeltd.co.uk/ in Staines as I remembered...so I haven't lost all of my marbles, well not just yet....:)

Cheers

Sorry for late reply Pete, long day at work!

funny that as I have been in touch with glenco today and Ive made a decision on buying a kit from them which I hope will fit the rail . They were recommended to me by a good source and are nice to talk to on the phone too.

Will try and update once once I figure everything out ??
 
good for you Dan, my first one from them was for fitting to the rail, they'll sort you out and as you've already found, they are very helpful..

I’m going to order the adjustable syntec in red and gauge with there kit, I think I’ve found the right adaptor from the pictures on there site to go in place of the 3 bar regulator I already have. just need to know how the original hose fittings goes onto the fuel rail as I can’t remember what ends it has? I will look tonight and try figure out what ends I need ect? Push over straight barbs coming off of the new regulator or threaded? Wasnt sure what the id of our fuel lines are iether 8mm?

It’s all new to me as I never thought about changing it for a adjustable fuel reg but now I’ve truly most of the way to modifying power I’m realising the more I go the more monitoring and adjustment I’m needing, which all makes sense ?? and makes me laugh when I read on some sites that the 944 turbos power is easily upgraded to 350bhp + for around £3000 yea right! Not if it’s done the correct way for longtivity ( not in my case and many on here anyway!)

im getting to a good stage of tune now and really looking forward to reaping the rewards after Wayne gives it a proper tune which it deserves all these years later of upgrades.


 
I'm jealous, I would love to get Wayne to bring my MAP up to date, alas all my pennies are going on a very expensive piece of copper for a certain project, no car tuning for me. Please give Wayne my regards, if he's forgotten my name (doubt it) just mention 'Pinewood studio's', he'll know exactly who you are talking about then..:)

Pete
 
Will do pete ????
just got back from a drive to do some more bedding in of the rings ect . I’ve worked out I’m getting in around 30-40 miles a night so pretty good milage considering I’m only driving around towns and factory estates every other night.

Pete I’m quietly scared of what Wayne’s gonna push the new motor as it’s driving so nicely it’s pretty terrifying. Thinking it’s gonna get it’s fresh guts frashed!

Put me out of my missery and twll me what sort of speed and revs in what sort of gear he will be putting it through ?

it Is what it is it’s just nail biting considering all the time and money I put into rebuilding the engine from scratch just as you did.

 
I've got a Sytec Motorsport fuel pump Dan. It's a Bosch 044 equivalent and the make is well known in the Subaru/Mitsy jap boy circles. I've ran it for about 6 years now, faultless.

Thanks Stuart,

thats good to know ???? I’ll admit there my favourite looking that I’ve seen.
 
Ideally you need to do much longer runs Dan, especially time wise...(2 + hours continuous driving) was what Lindsey Racing
told me to do on my NEw build back in 2016. Not short runs....

One issue was Wayne's very booked up and busy but I got a chance for an appointment within days of the engine being installed and finished. I collected the car on a Friday, did as much as I could over a weekend (500 Miles - up to 4500rpm when hot, and lots of loading the engine with heard throttle from 2000rpm upwards + Not staying at the same rpm for any time, always climbing and declining)
This included 3 Oil Changes (Inc. Running in Oil) and the then the bird was taken to the redline (6300rpm) on the Monday by Wayne.......

I think he used 5th gear, but it may of been 3rd...?

Either way he 'll need to look at your tune all the way from tickover to the redline, so hopefully all your hard work will not reveal any issues..

Hi Dan

As Roger has said, Wayne will need to map the entire rev line in each gear, this will include WOT in fifth. This is not a 'dyno' run to read max power where you usually only use 3rd and stay at max for a few seconds. This will take many hours depending on what access he has to your software, on mine I had the piggyback installed so it was just a matter of plugging the laptop in and he could write directly to my chip. For you he's going to have to open the ECU (DME) and replace the actual chip with one that's he's written, this all takes time. My map took approx 7 hours, I'm guessing a little here as my appointment was 10 am and he finished just after 6 pm but there was a short delay in getting started.

Pete
 
Thanks mate,

and lets hope so ey!

all I can say is with only 8psi of boost she pulls very strong around 3000rpm and up to 4000rpm is running very sweetly and purrs at idle at 900rpm.
with full bars of oil preasure and ends on 2.5 bars when fully hot running my mineral oil for running in the rings and bores I’m running custom wet culinders with racing rings and pistons/rods ect so it’s probably not the normal running in format that the standard allusil bores/rings ect would be??

i spoke to John at serdi U.K. last night who did my cylinder work for me and asked what he would recommend regarding the running in of my set up and he advised just to drive it normally up and down no more than 4000rpm and just go through the gears up and down, just no motorway long journeys at one given rpm and that’s enough as some people don’t even run them in and go straight to Dyno.

??????????????????

Hi Pete ?????????? i May be there all night then and have to sell one of the kids to pay for it !!!

I have the JMG chips in there at the minute which were for 18psi and my set up of mods for the short time they worked the car was superb and extremely fast in all gears! Hopefully he can sort it withought major headaches ??

if better get some overovertime in then at £125 an hour ??


 
Yes Wayne's well known for taking his time and being meticulous, the 1st time (at Ninemeister's Dyno) I was there for 10am and got away at 7.30pm!
The 2nd time at his new place it was more of a check to see if any changes had occurred before the car was Raced (He said his Dyno runs lower than the 9M did) so this was only a 10-3pm job....

Ok, Steel liners then.........?

Yes they are much different to the Silicone impregnated Reynolds Aluminium bores (Alusil)

Are you using a stock Cam? Web Cams (California) due a Mild upgraded one (274 Duration) which with a Flowed 2.5 head gave me +40bhp
on a Normally aspirated 2.7 engine. (All on stock Bosch Fueling / Ignition & AFM)

Yes at present I’m running a stock cam . It’s something I wished I’d changed whilst doing the engine build. ( another time maybe?)

what i did do however which I did take a gamble on, is I spent a hell of allot of time honing/smoothing out the inlet manifold ( not shiny and smooth like yours from LR but I’d say 45% smoother inside.

also I decided to go the full hog on my head myself and I’ve got a one off porting job on it as well as a very slight change in some sharp edges in the bowls and polished the bowls to mirror finish , in the ports ive tear dropped around the valve stems and left it swirly rough from the sanding drums to hopefully mix up fuel and air. Made a homemade flow bench.

Matched all the ports onto the manifold gaskets as there were some irregularities , so all in all it’s hopefully quite a big difference and everything hopefully is in place for what I hope can be tuned to be something quite speacial?? I put hell of allot of hours into it so I really hope so.

It's Silicon, Silicone is something else entirely.


 
Dan, from what I've read, the stock cam for the turbo is more than good enough, no point in changing it. It may be beneficial on an N/A but not the turbo for most power gain applications. Only really of use (debatable) if looking for massive power gains.
