Where to get a 5 bar FPR?

[kencom]

I've had a look, but struggling to find a supplier for a 5bar fuel pressure regulator for my 996t x50, any ideas?

[arebrec]

Can get them from any OPC i believe, Fearnsport supplied mine when the work was done

Ps, this is not my account lol

You do have a tune for the 5fpr - right?

Why are you doing this?
They are an awkward little sod to fit btw, this proved quite useful when I put mine in...

I currently have a tune from EPL in the states, since our recent communications I decided to go the remote tuning route as I am located just too far away from 911E (which is a shame!). My current map is 1.0bar peaking to 1.1bar in the higher gears, I have datalogged via Duramentric and all seems well, this data has since been double checked by EPL.

My injector duty cycle rises to as high as 94%, so no more boost until I fit a 5bar FPR & possibly 1bar Forge actuators as well, at this point EPL will send me a new map.

On another note I'm eager to see what times your latest 'Beast' runs when you unleash that extra 0.5bar (& I don't mean the 968! lol).

Good stuff, like I say the 5bar fpr can be a bit fiddly but certainly diy-able if you're the patient and persistant type and you're not too attached to your knuckles! Also, I have the uprated actuators and am convinced that they massively improve the way the boost is delivered and held and would certainly recommend fitting a pair.

[kencom]

I plan on fitting the Forge 1bar actuators (£370) and the 5bar FPR (£150) and running 1.2bar on my K24's. Although it does make you wonder that for just over £1k exchange I could have K24/18g's with new internals & 1bar wastegates included. But, then I would need clutch, yada, yada.........

My boost currently builds quite progressively with boost starting @ 2k, 0.3bar @ 2550rpm, 0.6 @ 3150rpm, 0.9bar @ 3650rpm & the full 1.0bar @ 4050rpm. This is in 3rd gear Durametric logs.

How does this compare with yours with the upgraded actuators?

That's interesting, I have the K16/24s which when tested in '09 (I think), were recording 0.3bar @ 2150rpm, 0.6bar @ 2575rpm, 0.9bar @ 2850rpm and 1.2bar @ 3175rpm which held flat to 6000rpm when it peaked @ 1.292bar by 6300rpm.

ETA, I think for the outlay you suggest the K24/18g's would be a serious consideration, but as you say then you're looking at 'little extras' such as injectors to get the best from them which is a motor out job (this is my current dilema). I think you're clutch's days will be numbered if you still have the stock one in, mine threw in the towel after 500 miles on the K16/24s.

1.1 bar to 1.2 bar is only going to give you and extra 20BHP max on the std K24 wheel, and a lot more heat (Think AIT now so you dont start to pull timing and reduce BHP). If you have the std Porsche Intercoolers, your next upgrade should be these to cool the air down.

The 5 bar will give you an extra safety margin at 1.1 bar on your DC, but taking the car to 1.2 bar will see the duty cycle in the 90%'s again.

Best of luck working with Tony.

Mr F
If you are sticking with Tony at EPL should advise you about this BTW.

[kencom]

I have the x50 intercoolers, so slightly better than standard. I don't intend to track or Vmax my car, just want a bit more wallop for the odd squirt or two. I will data log AIT's on a hot day & drive it harder than normal to see if these rise too high and/or it starts to pull timing.

At the moment I am going down the route of advancing timing bit by bit at this lower level of boost.

Thanks for the advice though, always apprciated.

P.s. I would love some 997.2 intercoolers, they seem the kiddies!

Sending turbo’s to the US and having them upgraded is very rarely the base cost you see advertised.

Say the cost is $1200. You will almost certainly get tapped for wastages. So add $400 for this. (1200+400 = 1600) now when you insure your turbo’s to America the recipient has to pay import duties about $200, they then pass this back to you (1600+200 = 1800)

You will then get charged in the region of $250 for shipping back to the UK ( 1800+250 = 2050)

All in all

1200 Build cost
400 wastegates
200 US import duties
250 shipping back to you

---

$2050

---

/1.58 = £1297. Now add UK customs charges import tax of 5% £65 = £1362 now add VAT from HMRC @ 20% £273 Total cost £1635.

So 1635, add your shipping cost over there in the first place about £125 Grand total of £1760…

And, this is saying the Turbo builder does not reject one of your turbos to be upgraded, If you are sending yours on an exchange bases, there is always the chance this can happen... If you get a rejected one, you will get charged for a full repair or replacement unit.

So the £1000 suddenly creeps up a little…

Eeeeek!

Maybe 500bhp will have to suffice for a while, it's a hard life!

X50 i/c's are all you need at this level, trust me you aint gonna make your car pull timing on the road !!! My tune running 1.2bar has never pulled timing on me despite cycled 0-190mph runs.

If you go hybrids, and plan on running hard and long, then yes, 997.2 seems the most economical i/c option.

Do you have 1bar actuators also?

[996ttalot]

Mate, you need to speak to Tony at EPL. If I was tuning it then it would be standard actuators on standard k24s. You should be running a 5fpr, but only if Tony tunes for it, otherwise the car will run rich.

The important thing is that you must ask Tony - he is the one tuning your car - sorry to repeat myself but he is the only one that should be giving you guidance.

There should be no reason why you cannot get 1.2 bar on k24s with standard actuators. Hybrids yes I would agree to run 1 bar actuators. Otherwise no.

BTW, just to add when you run 18gs you need to have at least 10k in your hand. You will need decent ICs, remove the restrictive intake, injectors preferably, then you should have new check valves, new oil lines, a full major service with plugs for sure, full datalogging and so on. It is not a case of just sticking hybrids on the car.

Let us know how you get on.

Thanks again Ken for your honest advice gained from experience.

Tony at EPL actually said that running 1bar waste gates makes a big difference, that's why I was enquiring. I'll let you know how it goes.

No issues. Actuator pressure does make a difference. It also affects your safety net and so on. A tune should be designed to work with a particular cracking pressure of the actuators. This is why you have to listen to your tuner, regardless of who that is.

Good luck and keep us informed as you how you get on. I hear good things about Tony at EPL.

No mate... I've been advised by more than one tuner that they are not so easy to remote tune to. K24's work just fine without 1bars imo... yes you'll get a bit more with stronger springs as they'll be able to hold the boost - but reality is, its marginal... if you really want more power, go hybrids.

[fstorm]

Any one got the part number for the 5bar FPR suitable for a 996tt ?
I guess it's a generic part made by Bosch etc ?
Cheers

Bosch part no. 0280 B02 722-2
