twofourten's G60

[twofourten 0]

Been sad this afternoon and cleaned the outside of the car & the alloys, then thought how much attention I pay to the inside?

 

It needs a good clean in here too, maybe next weekend, but this is how it looks at the moment...

Hello mate

 

Glad its coming together for you. Your in good hands at JKM 8)

 

I do like the OZ rims 8) would look good on yours

[twofourten 0]

hi stormcharged vr6,

 

thanks for help / advice with the project, always welcome and appreciated... Especially from someone who puts in so much time and effort on their own car 8)

I had previously noticed that my front grill was a bit broken & partially held in with a cable tie. This weekend, at a mystery location, it fell out. Now I have to get a new one.

 

Is it better to get chrome or plastic, is there a manufacturer that is better than the others etc? :shrug:

[twofourten 0]

Just got my dark tint inpro rear lights down

The fit is not as good as the OEM parts, but the colour looks great with the rest of the car

Went to JKM on 25th Feb

Now has the Koni coilovers fitted and a new ride height to match

Also replaced the broken side repeaters/indicators with smoked ones to match the rear clusters

 

Got the power graphs from JKM, but not entirely sure what they mean to be honest - but I'm working on it:

Can someone explain what AFR:P, PSI_g (pounds per square inch/pressure measurement?) and fFtlb (Torque) is please?

 

+ Meeting a man for a quote on smoking the windows this weekend...

AFR = air to fuel ratio. This is as it sounds, the ratio of air to fuel mixture. IIRC 13 is around what you want.

PSI-g = Assuming this is the boost your getting from the Supercharger. Not really dealt with G60's so not sure what is good or not. Atmospheric pressure is 1 bar or 14.5psi.

fFtlb = as you say, the amount of torque the engine has, effectively the pulling power of the engine.

Thanks very much Coullstar, that really helps - things were running late at the garage (due to the car popping water hoses under pressure) so I had to pick it up at 5:30 and run without asking questions...

your injectors are maxing out at 5000 rpm

 

check viewtopic.php?f=11&t=34451&start=360

[twofourten 0]

The original spec for the car was:

 

Ouput 160bhp at 6300rpm

Maximum Torque 165lb/ft at 4000rpm

 

Mine is now:

 

Output 165.4bhp @ 6000rpm

Torque 165lb/ft @ 6000rpm

 

The AFR thing concerns me, should this be more stable/level and if so can you fit some kind of regulator?

 

Trakx has said that my injectors are maxing out (thanks for pointing this out by the way) from a look at various threads I gather that getting red tops on there will help?

G-werks do a 315cc version, but I'm pretty sure mine is on a 68mm pulley so wouls I need a differnt cc injector?

[StormchargedVR6 0]

Mate , just phone Jim at JKM . He will sort you out with what you need.

Just made some money selling old stuff on ebay & more to follow

 

Already spent the funds at Arz Tuning (I love that website - check it out) on the following:

Wolfsburg Edition Aluminum Doorpins

Rieger Grill with Spoiler

E-code Headlight Housing (to fix my cracked one)

 

New stuff HURRAY :clap:

[coullstar 0]

No point in fitting Wolfsburg edition stuff, the car was never made there. Its was made in Osnnabruck (sp) in the Karmman factory. Common mistake.

[twofourten 0]

Thanks again coullstar, I never even knew what "Wolfsburg" meant to be honest - I just liked the door pins...

Given that the car's standard output is 160bhp and you're only making 165bhp your injectors are very unlikley to be maxing out. I'd take it somewhere for a health check, G-Werks or JMR - both experts. I was making about 180-185 on my old G60 with no sign of the injector duty going too high. Given your slighty erratic AFR you might have a duff lambda probe which measures the amount of unburnt fuel in your exhaust gases and feeds that back to the ECU.

 

When I got my SNS chip mapped at G-Werks they hooked up a wideband lambda probe to the exhaust which reads over a far greater range than the standard lambda probe. I then took it out down the bypass for some full bore third gear bursts to make sure the AFR was enriching under boost whilst Darren had his eye on the wideband readings - which is vital.

 

If you're running a smaller pulley you'll need the ECU remapped or you're running more boost and the ECU won't know what to do when it sees more air.

The rolling road reading is made with a wideband lambda probe.

The dip at 5000 rpm is the injectors maxing out.

From my car with sns chip and a Innovate LC-1 wideband lambda probe.

[Neil VR6 0]

I don't doubt that but is the wideband connected in place of the normal lambda and feeding the ECU with info or just held up the exhaust pipe for the sake of the plotting the graph? I just can't see how injectors are maxing out at only 5bhp over stock power? It's probably the equivalent of an icy cold day with a stock car, there should be more headroom than that I reckon

[twofourten 0]

Thanks for the feedback guys, it's much appreciated - I'm talking to the lovely folks at G-Werks at the moment about some further mods to the car toward Sept time, so fully plan to get the G-Lader service + rolling road before and after the works so I can track the differences.

 

I have heard of the lambda thing, but have no idea what it is really, I'll ask Rob at G-Werks (my email contact) and see what he thinks...

 

If you or anyone else has further ideas please let me know as the current result is disappointing and has to be improved this year :norty:

[Trakx 0]

In a rolling road usually the lambda probe is in the tail pipe. In my car i near the stock narrow lambda. Althought one can use a wideband to feed the ecu with some soft management i prefer to keep the stock one.

 

Concerning bhp. The car is making 12 psi, that is not much above stock. But more importante is that the bhp is not in the same "scale" as factory numbers. Soo this 165 can be really good or not.

In the rolling road i use, the first time my car went there it was almost stock but with a one way valve in ISV route, so it made a litle more boost on top rpm, with stock chip. It made 145.

Then with 68 pulley, chip and cam it made 175. This time a mate of mine with a stock 180 hp Audi TT went with me. The Audi got 168. That's 12 diff.

175 + 12 = 187 which is near the 190 we hear to be the target with chip, cam, pulley and ISV.

Looking through some old receipts I got with the car I found that DONE before me were:

 

Venom Motorsport

06/12/2001 - Supersprint oval back box & CAT bi-pass

 

Jabba Sport

29/05/2002 - 4 port Diffuser + Chip upgrade & 68mm pulley

 

This adds further frustration to the rather poor results, any other suggestions welcome... :help:

[dirtytorque 0]

it should make more than that on 12 psi although some will say that is low for a 68mm pulley on a car with no head work.

 

General health check as you would any car.

check static timing ok.

ignition timing setup correctly.

check fueling correctly.

check the engine has adequate compression.

 

as said above i'd take it to a specialist if these are things you are unable to check yourself.

You need to make informed decisions using data from test equipment.

Ditch that Jabba chip, they’re awful! I swapped my Jabba chip which came with the car to a SNS chip and the difference was stark. Mine ran far too rich with the Jabba EPROM

[twofourten 0]

Thanks dirtytorque,

 

List for g-werks so far:

Check Static timing, Ignition timing, Fueling & check the engine has adequate compression

Service & full G60 G-lader Full Service Porting/Polishing (Stage 5) option

LUK VR6 clutch (94.99) or maybe SACH (£276.60) one from JKM? The vast price difference might be the decider on that one

Gear box, repair or replace, and short shifter

CV boots (noted at last service)

Jetex Exhaust (377.95) or Milltek (890.34) from JKM - Again price may be the deciding factor?

New Alloys Fitting & Balancing (If funds allow)

Bigger Brakes (If funds allow)

Braided Brake Lines

New Hoses (If funds allow)

Red top Injectors or similar

Chip Upgrade

 

I have no idea how to do any of this myself and no garage even to try, can anyone provide me feedback on the clutch & exhaust options please?

Darren at g-werks knows the g60 very well.

you won't need to give him that list.

He'll be a good person to spk to about mods too.

I have found a place that will ship (from the USA) me the 17x7 OZ Allegerita HLT in Titanium Tech finish for a total of £950

 

Was also toying with the idea of a 4WD drive conversion with limited slip diff, have found a MK2 Golf Syncro (4x4) would this do the job?

 

Was going to spend some serious cash on the car soon so very tempted, any one care to share an opinion?
