Grounding Kits

[JJFukkard]

Has anyone ever used one of these?

I used to have one on my GTi-6 and it did improve idle, and with the rest of the small mods I applied I do believe it made a difference to the healthy output and running of my engine.

I can't seem to find a kit specific to Seat's but there is a universal one here.

Easy to fit, relatively cheap and worth a try IMO.

Below is my GTI-6's graph after a run at a club rolling road day in Padiham. Unfortunately they used a coast down method which gave unrealistic ATF figures.

With 17% loss my GTi-6 made around 176.5 bhp at the fly and 146.5 bhp at the wheels. Forgetting the figures for a moment and looking at the plot, the power delivery is perfect and smooth, the torque figure and plot too were good.

Mods:-

K&N induction kit (housed in the original air box to combat heat soak).
Devil decat.
Blueflame centre section.
Scorpion Imola rear section (over run because of the decat destroyed the Scorpion centre section).
Grounding kit.

Standard output:-

ATW - ~138 bhp ATF - 167 bhp Torque - 142 ft/lb

Modified output:-

ATW - 146.5 bhp ATF - 176.5 bhp Torque 147 ft/lb

Once I take delivery of my Cupra I'll be seaking to fit one of these as one of a few gentle mods.......ready for a REVO

did you get it dyno'd for std - or are those book figures?

Anyone interested in a group buy from this supplier?

Book figures. Plenty other GTi-6/Rallye's attended the event too, the near standard cars had noticable difference in plots and figures.

I understand what your saying, though I believe the mods applied had the desired effect.

See the explanation below, given by the creater of the kit fitted to my car:

Basically long cables and joints cause voltdrops meaning the motors, valves injectors etc may not be getting full operating voltages therefore not functioning to optimum.

An earthing kit takes big low resistance cables directly to critical parts eliminating this voltdrop.

By products may be brighter lights, revs not dropping when opening windows smoother idling.

EDIT: besides, it's not all about the power/torque output figures but the clean smooth delivery shown on the plot.

Yes !! Put me in if anyone else is interested,,

How about

Someone contacting these peeps and finding out if they would do specific kit.
It would require some near to them to donate their car for a day.
I read some positive reports on this procedure on 20 v turbo some time ago.
If we could get them to do the 1.8t engine then count me in

A universal kit sounds like coiled up excessive lengths of cable and bits too short

I believe this also had good effects on the Subaru's too when i used to be over on Scoobynet, maybe john banks could confirm this too as he was on scoobynet too.. and probably still is ..

 

[fickel]

I have sent the man...

an e-mail to see where he is and if he would build a specifc kit for the 1.8t
May need a volunteer dependant where he is based

Check out Pabs's website: www.leoncupra.co.uk
He's done the grounding kit mod, with a guide and links.

Yep - I have the grounding kit from these people - not too bad but dont expect a lot for your money.
Truthfully you could probably make a kit yourself using maplins/b&q or whatever, and probably cheaper too.
My grounding kit definately stopped me getting electric shocks from the car doors when getting in or out - not sure on performance gain tho. Kit cost me about £30, was dead easy to fit, and they tailored it for the leon (think they checked it against a mk4 golf)

The moment I saw this thread I thought of your kit, Pabs. In honesty, do you think it was value for money - or not?

I reckon it's one of those must do jobs - but I don't want to buy a s**t kit. I'd make one up myself - can you buy the cable from Maplins?

It's obviously possible to make one yourself, just make sure you buy the right kind of cable and that it's heat proof.

Also, get hold of a diagram of an existing kit. There are key points in the engine bay to earth, ie: inlet manifold, water pump, engine mount etc.

I'm not a hands on kinda person, I'd rather pay for something manufactured by someone else to save me the trouble

I would also say it's something that you fit, and initially you notice no difference. You would begrudge moving it though after being told by an engineer that it helps.

tbh, robdon has done a better grounding kit. The kit I got was ok, but i recon as the cable was precut to lengths it dictated what I could actually ground to. If you have a look at my guide, you can see which mounting points I chose. Most of them were good places to ground to, but one or 2 were purely as its the only place I could find where the cable reached.

TBH, I was happy with the kit as it stopped my static shocks. Thats why I bought one. As for other improvements, havent really noticed.

One last thing - My kit consisted of 5 lengths of wire. I recon you could use a 6th to take the alternator -ve to ground or the battery -ve terminal. Could improve things greatly. (So i have been told)

Make your own guys. I can get a price on reels of 8awg cable for you and the crimps on the ends if you like? Then you just cut the cable to the right length and crimp the ring terminals on.

you don't need heatproof cable, you need some common sense on routing to keep it away from the hot bits

..............I can get a price on reels of 8awg cable for you and the crimps on the ends if you like? Then you just cut the cable to the right length and crimp the ring terminals on. ..........

That would be of interest, thanks.

 

[Icecavern]

OK I'll have a dig around then

 

[Chaz]

I keep thinking about doing this, but I wasn't really wanting to spend £30-£40 on some wire and terminals.. Was planning on making one myself... Unless there is a cheaper alternative of course!

 

[Fl@pper]

made me own after seeing pabs kit n fitting

8awg cable for about £1 and some terminals robbed from work

ooh and about half an hour thinking routing and bolting it all in

cant get a cheaper mod than that - but did waste a few brain cells in the sun doing it

 

[Pabs]

I only bought a kit cos i'm lazy
