Fitted a full Nitrous injection system just before my summer hols :evil:
Full progressive sytem with race controller, arming switch, double bottles and heaters and the new style X10 pulsoid solenoid injector system, running an extra 75bhp and 75lbft nozzle and ported into the intake manifold pipe.
Amazing kick in the backside from the extra power and once I've nailed the settings and launch with the kit it should deliver some good 1/4 mile times :laugh:

OMFG :shocked: :shocked: :shocked:
Nice one. Can't wait to see what time you'll get now !! :cool:
You got the back seats out in the pic?

I have actually sold my GTi back in November as I got a new job and was given a company car (Golf Mk6 1.6 TDi 90BHP) :sad:. I still come on here now and again to see what's happening. That has just brought a smile to my face. You are a f***king hero. That is just awesome!
As we say over here in Northern Ireland 'Keep her between the hedges'.

haha!
insane project. can't wait to see videos/ times

Hurdy hurdy hurdy... you are utter brilliant

I reckon early to mid 12's on the 1/4 mile and 120ish terminals.
So basically I'm hoping for 0-120mph in 12.5 seconds :evil: as a start :laugh: :shocked:

Quality... :grin:

0-100 in 12.5secs???? are you kidding me? :drool: :drool: :drool:
Thats some going for a fw drive golf!

You're insane. But I love it.

I hope my DSG is as tough as yours. Those poor little clutches with 500 ft.lbs twisting at them.

Updated pic of revised bottle locations. Looks better and is more practical :cool:

That is truly mental..... :laugh:
-
Update..
Thought I'd resurrect this as I've just done a run with the new settings now I'm feeling better after being ill for a week.
Shonky 0-60 as I was being careful off the line as it was slightly uphill and I have to have the traction control off for the NOS. Also the rear speaker is in along with the added weight of the NOS system means the car is almost the same weight as if it had the rear seats in instead! NOS kicks in at around 50mph, but a picture tells a thousand words.....
(http://i156.photobucket.com/albums/t8/hurdy_album/c74270df.jpg)
St2+ NOS
20-40 1.5 1.6
30-50 1.4 1.5
40-60 1.7 1.4
50-70 2.0 1.3
60-80 2.3 1.7
70-90 2.9 2.1
80-100 3.2 2.5
30-70 3.4 2.8
60-100 5.5 4.2
As you can see the main difference is in the 60-100mph and is truly ballistic, with a decent launch 0-100mph in the 8's is on the cards.
A 4.2 second 60-100mph is faster than.....
Ferrari F50 at 4.3
Porsche 996 GT2 at 4.5
Ariel Atom Supercharged at 4.5
Lamborghini Gallardo Superleggera at 4.6
Lamborghini Murchielago LP640 at 4.6
Nissan GT-R Spec-V at 4.8 seconds
Audi R8 V10 at 4.8
You get the picture :evil:
Before the performance box reset I noticed that the standing 1/8 mile speed was 97.7mph and the 1/4 mile was 14.0 after backing off and dropping back down to 74.5mph.
Seriously looking forward to the next Pod day. Interesting times ahead :cool:

Yep, mental right enough :laugh:
To put it into perspective, I'm doing a terminal speed over 1/8th of a mile that a stock MKV GTI would normally struggle to do over a 1/4 mile run :evil:

Whats going to be next then? Bigger NOS injectors?
are you running a MiniMax progressive controller?

I am running 75bhp nozzles at the moment, but all I have to do is swap over the nozzles for bigger ones and the system is capable of delivering 150bhp and similar torque.
I'm running a full Max Extreme race controller, so I can progressively control the NOS in every gear and deliver anything from 0 to 100% NOS over a programmable time :cool:

How much more can the transmission take.

I don't know, but there are a few cars in the USA running 500+bhp on stock DSG clutchpacks, so I guess there's a little headroom still left :laugh:
-
i assume you have shares in some petrolium company? :grin:
i bet you fly through the juice!
loving the car!!!
-
I have my own local oil well called Shell :grin:
I AVERAGE 18.7mpg and it goes down to 8.8mpg when I use the NOS at full chat.
On a run I can still hit mid 30's on the motorway.
I'm not a high mileage user (approx 9k a year), so fuel isn't a major consideration. :smiley:
-
sounds like good good good fun............
b.t.w Are you going to vwfestival again?
-
You mean the one at Harewood Hall?
It is doable. I'm on nights, but I can always squeeze in a great show :cool:

yep Harewood 15th August.....
I will be on the ukpassats stand again!

^^^^I saw what you did there^^^^ :grin:

So, should I try the 100bhp jets?
:rolleyes:

I'm on 75bhp jets now :evil:
-
Update...
Took my brave pill today and dropped the 100bhp shot nozzles in, did some more logs, NOS setting adjustments and then a quick test with the performance box.
0-100mph in 9.2 seconds off a 5.2 0-60mph.....so that is 60-100mph in 4 seconds flat :evil:
That is equal to the Ferrari F40 and faster than the Lambo Reventon
The car feels soooooo strong in the mid-range with the nitrous on, but grip is still very much an issue. If I hadn't briefly hit the limiter in 3rd I reckon I would have been down near 9 seconds dead :laugh:
-
That's surely got to the one of the (if not the) fastest FWD hatch in the UK ?
When you are not running the NOS, is the ED as drivable and tractable as a normal car or a bit of a handful ?

The car is very tractable and driveable as a normal car. In April I drove all the way to the Nurburgring, thrashed it around the 'ring for 24 laps in one day and then drove it back home. 700+ miles out, 350 miles on the 'ring and 700+ miles back. Remember that my car also has R1R tyres, full suspension and engine/transmission upgrades and a Quaife LSD to help control the power :smiley:
-
Hurdy you go from 0-100 about 4 seconds faster than I get to 60 :grin:
-
think you need to upgrade from the 100bhp jets :grin:
you ever thought of stripping abit of weight out of the car to get the times down even more? Sayin that the extra weight pushing down on the tyres may be the difference now of stayin on the road or makin love to a barrier

Rods before 100+bhp jets :cool:
I have thought about stripping the car, but I love my tunes too much and that would mean that the Sub would have to go :cry:

Finally got some pics of the install under the bonnet :cool:

Update...
qtr mile...1st stab.
Had to go a little further afield to a longer,flatter, straighter strip of tarmac to get a qtr mile time up. Only had 3 attempts, and the 2nd one was the best. Trevor phoned me and told me off about not using the nitrous in 1st gear and gave me a few setting ideas to use nitrous off the line instead of revving the engine and using the turbo - definitely worked and is more stable a run off the line. Bare in mind that this was with the sub, spare etc still in the car and just the rear seats out as normal.
Increments to 100mph.

Awesome figures

not too shabby

is that a 12.4 qtr mile?
if so thats in similar territory to my m8s turbo'd ek civic, that does 12's all day long down Pod, his mission is to get into the 11's
-
4.4 0-60!!!! :shocked: :grin:

Yep, 12.4 1/4 mile = 1320 foot :smiley:
4.4 0-60!!!! :shocked: :grin:
That is done by using the nitrous instead of the turbo to get off the line - lower rpm and a cleaner launch. :cool:

Update...
Went to have a dyno run with the nitrous today. The guys were very helpful and one of the operators has nitrous for his car, so I was in safe hands. It was a Dyno Dynamics "pessimistic" set of rollers at RS Tuning in Leeds. I chose their dyno specifically as they are just about the lowest (as most consider) that are near enough to me who I trust to dyno it correctly.
So, below is a pic of how they had to strap it down. They said strapping down this way loses 2-3% as it pulls the wheels so hard down into the rollers :undecided:
(http://i156.photobucket.com/albums/t8/hurdy_album/Nitrous%20install/100shotnitrousRRstrapdown.jpg)
Here's the bit you've all been waiting for...
(http://i156.photobucket.com/albums/t8/hurdy_album/Nitrous%20install/100shotnitrousRR.jpg)
438.7hp and a peak torque of 510 lbft on nitrous
339.8hp and peak torque of 381lbft without nitrous.
The settings are less agressive for the dyno than on the road as the nitrous wasn't even set to start until 3200rpm.
Absolutely no sign of slip on the DSG box and AFR's on nitrous were a solid, held 11.5.
Interesting for me is that my torque on nitrous is as high at 6000rpm as the peak without nitrous. Also I'm making more power at 3500rpm on nitrous than my peak power without. :evil:
This is a REALLY impressive modification and it would be interesting to compare it to say, the GT2871R that I was thinking of fitting.
-
Awesome :cool:
-
How long do those 2 bottle last Hurdy? And how much to fill them up?
-
£40-50 a bottle (11lb) depending on where you go.
I'm using the nitrous quite a bit more than I normally would at the moment for settings etc and they lasted me 1.5 months. Normally, once I've finished the settings I reckon they will last around 2 months on the 100bhp nozzles. You can double that time for 50bhp nozzles and again for 25bhp nozzles. It is probably more accurate to say how many runs and that would be around 40 quarter mile runs on the 100bhp nozzles, 80 on 50bhp and 160 on 25bhp. Based on using around 10 seconds of nitrous a run :cool:

Sorry to hear john about the Engine going wrong mate. :sick:
Hope she's back to full health soon mate.

What's happened??
-
Normal service will be resumed as soon as possible :cry:
-
Oh dear! Good luck with the rebuild ... 2.2l conversion? lol
What failed?
-
Head gasket leaking - needs a steel gasket
Exhaust has a cracked flange weld at the turbo end (probably due to heat/extra gases) - needs a re-weld
Clutch is slipping (only on nitrous) - upgraded clutchpack needed unless I take the nitrous off in which case it is okay.
Fuel pump cannot cope with nitrous AND engine demand - upgrade fuel pump unless I take the nitrous off in which case it is okay.
440bhp and 510lbft was always going to stretch the car. :shocked:
-
what a result 510lbft 40bhp :shocked: 339bhp a little lower than what you got on our dyno?,
It must be a monster to drive, most turbo cars with 400+bhp have loads of lag, but to drive one with 400bhp and 510lbft without any lag must be utter madness.
I did two ED30s yesterday, the second one was dsg and we managed to get 277bhp from the stage1 map and on the test drive I did not want to give the customer his car back. :grin: I need to convice the wife to let me have the deposit for our house so I can get me a ed30 dsg ..lol
Nick
-
Great car Nick. 5 door dsg mapped is a hard car to give up :wink:
Especially with the extra doors, it would win the family car argument :wink:
Got any graphs of the Ed30's you ran with your map on it? :smiley:
-
During testing it was a complete animal Nick :shocked:
3rd and 4th gear pulls are insanely fast and it pins you fast into the back of the seat.
I just need to know if the REVO DSG software will work okay with uprated clutches before I make a decision on where to go next.
Hopefully get the car back in tiptop condition with the clutchpack and a stronger gasket and downpipe and take it from there.
I still don't think that there are any companies that will do just a rod set for an edition 30 as the gudgeon pins are larger on the ed30 cylinders. So I may have to go for rods and pistons, which will be ££££ and on my set-up may mean I go for another car instead??
If I go for it then the N2O system is good to give me 490bhp and 560+lbft and that may mean stronger driveshafts??
Also I may go for hybridising the K04, which should help with airflow and over 500bhp with the N2O. :laugh:
-
You're definitely certified John. :evil: :evil: :evil:
If my Ed30 wasn't so bloody poorly all the time and my bank balance allowed it, I would have given you a run for your money. :laugh: :laugh: :laugh:
Mind you, I spent almost 10k pounds in only a few months on my mods... shudder to think what you've spent. :shocked:
-
^^^^ not sure how much I've spent now. I've lost count. It may well end up being the first UK VW with £50k in it :laugh:
-
Good to know the limits of when too much over kill actually becomes too much overkill. :grin:

I would have killed my dyno then, It nice to known someone like you IMO is a propper tuner, tune to the limits and beyond, its the only way forward and to be at the top of the game.
On thrusday we ran a our C20let to 399bhp at 14psi on the dyno and we could not load the car up to the 20psi its been mapped for so, today it went on and ran a 11.4s 1/4 TS@131bhp at USC at Pod without nos, Thats with over 8 years of fuel and ignition mapping on the same map and a few melted pistons with a few ripped apart gear boxes.

Well considering that you've inspired / goaded many others - including new and unsuspecting members of the forum - to mod their cars, I reckon you must be directly and indirectly responsible for around 2 million pounds to the UK Tuning Industry... a one-man economic stimulus :grin: :grin: :grin:
Its all in the national interest of course, keeping the economy afloat etc... :wink:
-
What an anticlimax.
All that effort and time spent.
Then put back to stock and sold.
Wasting money like that, are you sure you are not a Lancastrian?
-
There comes a time when you either bite the bullet and spend thousands on modding a car further, or spending those thousands on a new car. I chose the latter. I don't regret it, yet!!
Ask me again in a couple of months :wink:
