although i love to read these threads it must be very confusing to new members of scooby net
When I purchased my last turbo there were 2 members who ran 400 bhp on an 18g with std wrx engines, I was very tempted but when i talked to my mapped he recommend something different for the 400 bhp figure I had in mind - glad i did as since then I have seen very few cars hit high figures with a 18g - the turbo I fit was great, the mapper did his job and i got the car I was after
to the op I recommend you get hold of a mapper that you fully trust and ask him what he would recommend - there must be many many snetters out there who read threads buy on impulse and end up very disappointed when they take the car to be mapped to be told they would not recommend this turbo \ injectors \ intercooler
I haven't got a clue about turbos ( like many people on snet) I can only compare turbos I have used but I have been tempted to buy things form what other snet menbers have told me and ended up worse off

Great result Ash, 100bhp up at 4000rpm 
BTW the 411.1bhp graph you posted above is my 2.0L STi5 with the 380, not Martyn's
For reference, the 420 on my car made 444bhp & 398ftlb
Jase.

Umm can't really work it out by looking at the graph, all so on my graph the boost comes in faster on the road hitting full boost by 3400-3500k revs.

I really would love to see a straight comparison between the 18g, 20g, 380, 420, 321H, 321T, 321T+ and 321V on a 2.0L... all on V-Power only.
I know it's asking a lot, but can anybody furnish us with suitable comparisons...

Sheesh, I know... but it's something we ALL would love to see, isn't it? The ultimate 'decsion maker'... lol

But on what? Standard sti or a built engine. I guess some will perform better with some simple mods whilst others will require more money to be spent to get the most from them.
Surely, the 'best' turbo will be the one that comes on boost the earliest and holds boost the longest, along with a fast spool?

Whats 65% of energy got to do with anything ? Thats got nothing to do with power.
Im sure that a meth or ethanol mix will give you at least 20 - 50 hp more top end depending on various factors. And it will also gives more power along the whole power curve. So that all helps spool up. The comparision wouldn't look so good if the power curve was 10% less everywhere !

400hp is a good result in anyones book - but its not really fair to compare them on different fuels. Better fuel is great gives you efffectively a bigger faster spooling turbo.

So I had a remap with 10% (well, 5 litres / tank) of this stuff on Friday last week. Remap courtesy of Simon.
Previous deltadash power on one bottle of NF / tank (expensive!!) was: 353bhp / 354lbft @ 1.4 bar with a td05-20g.
After remap with 1.5 bar - 391bhp / 392lbft! Deltadash figures again, obviously, but using exactly the same settings as last time.

METHANOL 10% gains
not in my experience-10% is in someone's imagination -if it gave that sort of gain there would be a lot more using it. I run 10% meth and the car is mapped for it, didn't make any difference to spool-up. What did make a difference was a water/meth injection system costing loads which allowed more timing resulting in the things you mention, spool-up 300rpm faster and gains across the rev-band- the ignition is nearly maxed now-you wouldn't do that by just adding 10% methanol. Might see 10-15% gains if the car was run on purly on ethanol

As any tuner will tell you cars/mods/turbos are not all created equal - meth / ethanol works better in some cars than others for sure.
Just because it didn't work for your car doesn't mean it will not work for others. And of course the opposite is true.

Here's a great example of what better fuel can achieve

Duncan, there are two sets of curves on the graph above... the lower one is straight V Power, then we did a 10% meth map on the same day. So yes, they are directly comparable. Both are at 1.9 bar and are very similar curves.

My experience with Meth is that a 10% mix is generally good for 7% extra power and maybe 2-300rpm in terms of spool up if mapped for it across the whole range. This does get better the higher the mix of course, I have seen on a T (Plugging the competition again Mark, lol) gains of nearly 50hp and 90lbft on a 20% mix when mapped for the extra ignition and boost.
