Guys just wanted to know what bhp gains i should get with the following mods on a stage 2 remapped 225 Bam engine.3inch downpipe and D-Cat with custom built exhaust,badger5 intake pipe with induction kit,Forge dv with yellow spring,4bar fuel regulator,Forge boost hoses

Also is there any other mods i need for a stage 2 other than a FMIC
 
Going off recent threads on here it will probably get you bent rods!
 
i think your car will be around 275-285bhp. you dont need to change your rods at all, theirs been dozens of gt28 turbo conversions runing 330bhp plus with 300 plus lbft, on standard internals with no bother at all. its like anything you can be unucky and you bend a rod, anything at any time can go wrong with any engine. enjoy your car.
 
Bent cons mines in being fixed right now no 2 rod bent.

there are several 210/225 engines loosing their rods... so this is no assurance at all
 
If you are going to that sort of expense it's a no brainer really. Losing a standard engine is bad enough, losing one that you put ££££'s into would be heartbreaking, especially when it could've/should've been avoided.

Depends on the risk factor. Several out of how many? If several were 10...out of one thousand S3's for arguments sake, then while it may be several, it's a pretty small risk factor of 1%.
 
I rmemeber when I was first looking at getting 1.8t's and everybody was barking on about running 300bhp without changing any internals. But now they are getting on a bit, it seems there is a risk of bent rods, albeit not a massive risk. Its not too expensive to have it done. I think 280 seems the norm for those kind of mods
 
Guys i think were going abit of the topic now.i jus wanted to know wot sort of bhp gains i would get and if theres any other mods i can do
 
The best mod in my mind is forged con rods and not have to shell out £2000 to fix when it goes BANG. The shells looked like new but I'm having a new oil pump fitted.

I think we would all probably think the same if we bend a rod and had a large repair bill. But it would be a biased opinion i.e. before you bent a rod, I doubt you'd have thought it was the "best mod" :) ?

Such comments, without actual facts to back them up, is nothing more the scaremongering.

What might be useful is to start a poll: Have you bent on rod on your stage-1 map? If the poll was large enough, then people would be able to make a judgement on how risky it is to go stage-1 on standard rods. (but then again, I'm sure there's plenty of variables at play - ike what map you are using, what your torque is, what the age of the car is, what the power delivery is like etc., so hard to judge)

One or two people stating they bent a rod isn't really an argument for promoting changing your rods being the best mod. Because for everyone one or two that say they've bent a rod, I'm sure a multiple of that number could come on (with much greater power\torque) and state they haven't bent a rod.
 
May not be the best mod but is the most sensible if looking for lots of power IMO...

Depends what you call lots more power.

I don't see how it's possible to say it's a sensible, in the sense that's being implied i.e. that there's a big risk here. It really is scaremongering unless there's facts to back it up. If there are, then such facts would be benificial to everyone on here, but I've not seen them.

Plenty of mechanical parts fail. What's to say it's not a problem with something other than the rods that caused peoples bent rods? What's to say that an extremely small precentage weren't just dodgy?

The only evidence I see is one or two people saying they got bent rods. With no information behind it. What maps they were using? What max torque they had? What bhp they had? What the power delivery was like? What other problems that car had?
 
A remap could he deemed lots of power, it's certainly more than the car was built with.

Silly to think that reliability is going to be as high when running more power.

I'd never heard of a single bent rod on an S3 onthis forum up until the last 6 odd months where there has been 3 occasions, on the height of it that doesn't seem many I agree, but the possibility of it happening is certainly there. It's funny how none of the S3s mentioned were on a standard map...

So basically you are saying anything above standard is lots? Without quantifying what "lots" is, it's not a very useful description. A standard stage-1 map is only about a 10% increase in bhp (225 to 250).

Also, are we talking about more bhp? more torque? What factors affect rods getting bent?

Correct me if I'm wrong, but I don't think anyone has said you won't increase the risk of reliability problems if you start pushing an engine beyond what the designers designed it for. What is silly is making out that we should all change our rods, simply as one or two have seen bent rods, without any other information to back it up.

I don't think anyone is saying the possibility isn't there. The question is more what is the probability of it happening. There's a possibility of everything happening - doesn't mean you guard for every possible thing that may happen.

Not really that strange. It's just one variable. Just because some event happens, and they all have a similar thing, it doesn't mean that thing caused the event.
 
I haven't told everbody to change there rods, just that I think it's a sensible thing to do if your upping the power of your car, I speak from my experience, if people choose to change there rods then fair enough, if they don't then that's fair enough, I couldn't give a toss really, just letting people know of what "could" happen...

Not knocking your opinions or experiences. But telling people that it's sensible to change rods implies there is a sizeable risk of them failing, which there doesn't seem to be.

Apart from one or two people with bent rods, I've not heard any sizeable numbers, and we don't know exactly what the cause of the rods getting bent was. So I don't see where the evidence for saying it is sensible to change your rods is.

As for letting people know "what could happen" - like I said, anything could happen. But you can't go around replacing every part of your car just because it could go wrong.
