So I guess that includes the coolant too?

Sorry, what do you mean by go standalone?

Cheers.


No problem - yes, coolant as well.

The injectors / fuel management weren't done on the rebuild. So, it's already got 347fwhp but if you want to take full advantage of the rebuilt engine and up the boost :twisted: , then you'll need bigger injectors. And the SAFC-2 is fine up to a point but if you want a real animal, best to look at a standalone ECU to manage everything.

If I was keeping the car, I'd go for the eManage Ultimate.

Anyway, without upping the boost, you already have 347fwhp. That's already fairly fast.

If I had the fuelling side and a standalone or Piggyback ECU in, I'd say it'd be producing 400+fwhp - and I probably wouldn't be selling it :D

Oh right, ok. I thought you said you were going to be upping the boost once you had the knock sensor out of the way?

What was the engine rebuild for then? I take it that parts of it are above the normal stock rev3 engine then?

Cheers.

Just noticed on your dyno run it says 347bhp and 310 at the wheels? But I think you said 347 whb and I thought whb meant power at the wheels?

Just wanted to check that with your fuel computer and ebc you can go from performance mode to economy at the press of a button? Like you can program in different profiles with different mappings, etc?

At the moment I find it really frustrating when I have been driving economy for a while for when I now need the power and it doesn't give it for ages until you have been driving hard for a while and thats always tricky with busy roads! :(

I guess it should help with fuel economy too. Whats your mpg like? Im guessing quite low when in performance mode but what do you get if in economy mode too?

Cheers.

Just checked my first post and I have fwhp (FlyWheelHP).

I never drove it in economy mode :twisted: :D

And once you start to modify it for big hp, you don't / shouldn't start to look at mpg !

I know the AVC-R has a Hi and Low Setting (A and B) and takes 30 secs to change it on the menu. Not sure on the SAFC-2.

To be honest, the best way to go into economy mode is to drive without a heavy right foot ! if you are revving/boosting no matter what mode you are in, the engine will use more fuel.

Very true, I have the same problem at the moment, I call it heavyfootitis! Thats what I am going to say if I ever get pulled! "Its not my fault officer, its my condition, something I have to live with everyday!" lol

Sorry mate, didnt see the f in front of the whb, I think I may need some glasses soon! :(

So after the engine rebuild you think it would be roughly 400ish fwbhp without doing anything else to it? Or is that after it gets remapped? Any idea how much its going to cost to get it re-mapped?

Cheers.

There is an uprated clutch in it - so, just tell the officer "The clutch was much heavier, so I thought I had to press harder..."

After rebuild, nothing has really changed, except the engine will be bulletproof and ready to take more power.

The guy will de the remap as well - now, as he is mapping it, he'll be watching to make sure the engine doesn't run lean. if it starts to run lean, then that's where you'll need to look at the fuelling.
Basically, before I had 347fwhp and that was probably on the limits of the standard engine. Now, I'll have 347fwhp and you can drive it hard without worrying.

You have two choices - enjoy as is and know that engine is bulletproof.

Or - up the boost - but fuelling will need to be addressed. The limits in going for more power are engine itself, turbo and fuelling.

On fuelling side, not sure how far you can go on std injectors and SAFC-2 - I think someone in the US was over 400 on standard injectors but that was with a standalone ECU.
On turbo side, that turbo is rated to 430fwhp. Now, I'm no expert but you aren't supposed to run turbos on their limits. So, having 400fwhp seems reasonable.
And the engine - without replacing conrods, I think the engine should easily take 450-500fwhp ?

Oh right so as it stands you cant really up the boost without first sorting out the fueling?

When the guy remaps then its not to up the boost or power or anything, its just to sort everything out with the new engine build?

So what enhancements has he made to the engine if its still got the standard injectors? I guess just toughend up some componnents, etc?

Cheers.

He'll safely up the boost up to the point at which it starts to run lean.

The engine has forged 87mm pistons with sleeved block, uprated head gasket, arp head bolts, new big end bearings. I'm not a mechanic, so don't know exact details but basically only standard parts not replaced were the conrods - but I think std are good for near enough 500fwhp anyway !

Oh right, ok cool. :thumleft:

Looking forward to seeing her mate! :)

Oh, one last question (im sure it wont be but please bare with me anyway!), I noticed you got 205/50/16 on front and 205/55/16 rear, is the back profiles bigger enough to handle that much power?

Only reason I ask is cos I have:

205/45/16 front
225/45/16 rear.

But im not an expert on these things as you prob noticed by now! lol

Cheers.
