Anybody tried one of the rails as per the link below?
Just wonder why Carl Davy's are £300 and these £120?
I don't fancy a badly made fuel rail that leaks!!!!!!!!!

Its the same company that makes the shi@e quality turbos.

You get what you pay for and with fuel i wouldnt be taking chances.

 

Carl's are custom made in the UK, supplied with high quality Earl's fittings, can be centre or end-fed, and are heat insulating.

These eBay ones will be made in China or Taiwan, are supplied with four unbranded fittings and have no insulating capability.

There's no reason to assume that these cheaper ones won't "work adequately", but there's equally little doubt that with Carl's you're paying more for a better product.

 

I can vouch for the quality of Carl's rails

The production quality is excellent, and have been in use on my 570hp classic for 2 years without any issues.

 

simply put, if you cut corners with tuning you scoob, you'll end up with a blown engine. simple as.

the quality of the workmanship is no where near as good, and even if they look goo on the outside what do they look like where it maters? on the inside.

ebay for tuning parts for scoobs is a big no no im afraid.

 

3bar of fuel pressure is low in the fuel world. they aint bad either, ive used them. also i get my fixings a top quality plumbers near me. it isit a WRC car

 

If your power target is under 450hp, I'd stick with the standard rails setup in parallel configuration. - If you want to run -6 Braided lines, just buy some weld-on fittings and get them brazed onto the rails.

Your rails can be modded for around £50 and probably just as good, if not better than the ebay offerings.

 

These ebay rails are good. i'm using rails and fittings from Taiwan and there is no problems. injectors fitted perfectly. £300 are overpriced.

 

yet!

Like others have said you get what you pay for, how long will your cheapos last compared to Carls? what damage will be done to your engine when yours decide to give up?

 

all are made same way. just in Taiwan making rails are lot cheaper and they making hundreds. but if you make only one pair you need setup lathe every time and it takes time. time is money

 

I appreciate that, but with Carls at least you know you are getting quality for your money, with the Taiwan stuff its all a bit of a gamble, just look at some of the fake turbos that end up over here which come from Taiwan/China etc as an example of the poor quality

 

Iv got these, or what i think are these. I got mine from Harvey smith though, cheaper!

look the same huh?


so what if the fittings dont say goodrich, or earls, why would you pay twice the price for something that does the same thing - its beyond me?

Be warned, i had to grind a small redundant part of my v5 manifold away that fouled the rails, but i think it was for the old rails and didnt cause me an issue. i mentioned this to harvery but he never got back to me.

would i buy them again? no id go topfeed + posh inlet

 

You are being a bit silly, it isn't exactly rocket science making those rails. A friend of mine made his own. I doubt that those from Ebay are crap.

I still run modded OEM rails though.

 

Why on earth do you think a CNC machined block of aluminium would "give up"?

If they fit properly and work well on day one there's no reason to think they won't last the life of the car -or at least as long as Carl's. If anything one could suggest that the eBay ones may last longer as they're a simpler design with less to go wrong (and fewer bolts to work loose).

As I said earlier, you are paying more for a comprehensive product with Carl but that's no reason to suggest that these alternatives are likely defective or dangerous in any way. Let's have a little less mindless scaremongering and a bit more simple common sense.

 

Going by some of the other shoddy tat weve seen from Taiwan/China I fail to see why they will last TBH, Buy cheap buy twice

 

Three quarters of the components in the computer you're using are likely made in Taiwan or China.

As above we're not talking about a turbo, just a couple of blocks of aluminium. How exactly do you think they will break/wear out/fail to "last"? On what basis do you suggest that Carl's will be likely to "last longer"?

Are you an engineer of any sort? Are you implying that the rails Harvey sells are likely to be shoddy tat (given that they appear to be the same items as in the eBay listing)?

There certainly are examples where the "buy cheap buy twice" doctrine applies, but there are equally also cases nowadays where volume production overseas results in a product just as well made but for a lot less money.

 

i wonder what they are like on the inside? look pretty on the outside, like most intercoolers from ebay, but they don;t perform well at all, wonder why that is?

 

You don't have to be a rocket scientist to tell what they look like on the inside. They will, no doubt, look exactly the same as Carl's as they are machined via the same techniques on the same sort of machinery.

There is one hole bored all the way through from one end to the other, tapped at each end for the fittings. The injector bowls being milled through the top. Add a few more passes for material removal and they're done. There is nothing complex about it. Sure, Carl's are insulated, but without actually testing to see how much heat is imparted into the fuel (and how much of an effect this has on combustion), it's impossible to know what benefit, if any, the insulation has.

Your point being? An intercooler is a far more complicated item than a fuel rail, which is, at base, just a couple of receptacles for the injectors connected by a pipe with some method of connecting the fuel fittings at either end. There is no rocket science involved here, and little opportunity for one set to "perform" significantly worse (or better) than another.

 

Jesus Christ you really are a f,ing ****, ok go buy your cheapo tat and do what you want with it shove it up your hoop if you want, me ill go and waste some money on the up market ones

 

Lol, talk about miss the point. If that's the best response you can come up with, it doesn't exactly say much about the strength of your original proposition, does it? Still, you know what they say about the fool and his money.

 

Two of my engines use these fuel rails, Darren's P1 2.5 has them and Wrighty was looking for a set when he was getting something else from me as far as I can recall. I have a set of phase 1 and a set of phase 2 here for future requirements. I do not market these but can sort out anyone who has a requirement.
Let's be practical. Dimensionally they are spot on. I bought one set first to check them out. What are the other requirements? Well because they are accurately made and dimensionally correct, they fit and hold the injectors properly with no leeks.
What can go wrong? Very little. I guess if the material was total crap and they were subject to vibration they could in time fracture but my judgement is that will not happen because they are a well made item and in any case it is improbable anyway.
I don't have a Rolls Royce at present, just a Subaru.
I don't wear Gucci shoes. This pair came from Tesco.
I am happy with the washing powder from Aldi and the food my wife buys from there or Morrisons and my Pulsar watch keeps good time.
If you guys want to shop at Fortnum and Mason, wear Armani and have Breitling watches that is fine by me. Guess you have more money than me but I will continue to exercise sound judgement and use what suits me.

 

newage ones dont fit! although apart from that they are good quality although they dont fit lol back on the hunt again

 

I have no interest in the New Age and the ones I use and the set used by Wrighty are not e-bay. Wrighty, sorry if I didn't get back to you. It can only be because it was overlooked but on version 5/6 cars we have to take a bit of material out of the rail but they are a straight fit on versions 3 and 4.

 

dont worry about it harvey that problem was overcome ages ago, 10 secs with a grinder on the inlet for me though, no way i was grinding my new rails haha. as said though they are good and what could go wrong?

 

I tend to agree with the view of these rails being good value for money. As already said, they are a lump of ali, if they fit well and dont leak then what else is there to go wrong?
I will be buying a set myself soon. Many places in the uk have their own products made in china etc as they are cheaper to get made there, also wouldnt the standard rails be made overseas aswell lol, does that make them crap also? These ebay rails prob cost more to make than oem rails. So for me, i think they are fine and would never pay £300 for a set.

 

I was happy to try a set as an alternative to using adapted O/E fuel rails with ends braized on. If it worked great and it did.
No way can I justify £300 for a set of rails and most of the engines we build are done with "great budget constraints" so while I will not cut corners I will look out for cost effective solutions.
