Limits of the ED30 tuning

[Hurdy]

So everyone,

I've been reading the GOLF+ feature on the 2.0 TFSI engine and the various upgrades that are available with the stock K04 on the ED30 and the upgrades from the standard GTI to a K04. Most say that they are only tuning into the early 300+bhp, but what exactly is the limit of the ED30 in terms of power and bhp without changing the turbo, but changing all the other bits that count (remap, zorst, HPFP, I/C etc).

Tuners all seem to be quoting between 300 to 340bhp and up to 335lbft.

I already know Vtec has managed over 360lbft and I have had 333bhp, so surely these must be approaching the upper limits?

Why is it an ed30 with a wrong bore exhaust (2.75'' instead of Correct 3'' has this super high 360Lbs ft of torque??? , How can that be, surely thats gonna have a prefound effect on the Engines potential torque??.Isnt that just like putting a Cat back system on instead of a Full System???.

Im Bemused??.

I was a little suprised that it made the torque it did to be honest. But it did it on 6 different runs on 2 different days. Would still like to see what it makes on other rollers to compare though..
As for the DP, fook knows. Might have something to do with the back pressure..  TT? I know DJ Horace said he wished he had gone with the 2.75" now instead of the 3"..

Phil my comments

It seems to be a strong std car
Its on APR rollers (which may read high)
Its on that style of dyno (dynamic) with various correction factors
REVO hits very quickly at low rpm (very noticeable in Hurdys prev graph comparisons) , so maybe this combined with the way its measured skews the 'measured' torque peak
We would need a before/graph for vtecs car on the same dyno/same day (pre and post mods)
I'd be interested to see Vtecs EGR readings under full load tbh

as for the exhaust, I think the milltek still removes some of the other restrictions.
Small bore can be better in terms of flow at lower rates.
This in theory could help the very quick spool/torque peak seen in vtecs car

What we dont see though is the higher rpm 'limits' that supposedly tuners say we need a 3 inch bore for!
In theory vtecs car should perform better at lower rpm then flatline at say 6500rpm ?

i have an idea i will put my stock dp back on the car for the rr day and then me and ben will be running the same but me on stock dp and ben tell us what revo settings your running and i will run the same and then we will see what happens.

Is the stock DP 2.75" 
At the end of the day guys, I don't see mine being anymore powerfull than other ED30 with the same mods. K4iths ED30 ran only anout 10bhp short of mine on the same day, but he only had the Map and intake, no TBE.
Mat's will be a good test, as he also has Revo and Milltek, plus a few other little bits. So on the same rollers should make for interesting results. Only thing is, what rollers, Prosport or Weston's?  As if us guys at Prosport get good results, then I can just see the same arguments coming up again about whether they're as good as DD rollers..
What to do eh..

Oh crap (doh!), Mat don't forget i'm Stage 2 now.. What difference it'll make I don't know, a little bit I hope..

thats ok fella i have a mate who is a revo dealer in halifax so might get it put on  but keep stock dp just to see how it goes.

Only £50 sheets mate, so may as well..

you are stage 2 not stage 2 + as you dont have a pump
