i dont think that the grounding kits gain any hp, it just probably restores the hp lost by bad grounds...just my 2 cents!!

 

Thats the same thing in my book

 

I was the one who helped Paul make the measurements for the SC400 kit. Do a search and you'll find my thread with pics. I'm not sure if it increased HP, but it sure made a difference in throttle response and a little smoother idle. I'd give it a .

Johnny,
I've sent you a PM on the springs
Can't wait to see pics of your ride w/ the new shoes.

 

It has been proven that grounding ktis can gain up to 15 hp on a civic or sentra. However, the ideal ground points were finely tuned on a dyno. We also don't know how bad stock grounding is on a civic, sentra or sc400.

Any gains on a lexus sc400 so far is only hear say. There have never been any dyno's to prove whether grounding kits help or hurt.

 

Here are the grounding points I used for my SC400

1) Batt Neg to to passenger side fender near stock air box
2) Batt Neg to ignition controller on driver side fender
3) Ignition controller to dipstick mounting point on engine block
4) Engine block to intake manifold
5) Engine block to firewall stock ground point
6) Firewall to throttle body/intake manifold
7) Firewall to passenger side valve cover/engine block

 

Check out what I whipped up today in a half hour. Its very simple, but the 4 gauge should do the trick. I was going to run a new pos. terminal -> alternator line but I didnt have enough wiring, and it looks like the stock wire is something like 0 gauge already

 

Because that's what was available at the time of purchase!!

Yes, working on the spacers - posted a question in the FI section. 5mm or 15mm??

What do u think?
Jonny

 

are you gonna post them pics or what?

 

DX3 are the wheels you are putting on from Mikeloc in CA?

 

Congrats Johnny. Sounds like you have several projects goin at once. Post pics up when you get it done.

 

Those are the ones!!

Peace,
Jonny

 

Guys,

Sorry for the absence guys - got done real late last night and it was too late to take pics. Then today I had a guy come to pick up my old wheels and that took longer than expected.

I got the car cleaned and she is ready to take pics - but now it is dark

Wheels look great - grounding kit was a real PITA and I didn't notice any improvements!! Don't even know if I need to lower the car - seems like it is sitting at a pretty nice height right now.

Thanks Chris and Gene and everyone else for the best wishes,

Pics will be up tomorrow,

Jonny
