180hp 1.8t in Bug

This looks awsome!!

I think he meant "If? she starts.. more like WHEN it starts!"

[Panelfantastic]

You're right Scott. I forgot how "sensitive" Dent can be...
I predict it fires at the first bump! Jason has great eye for following up the details and those 034 guys have a really strong rep... perfect combo for a worry free initial start.

What is the common way to hook up the thermoswitch for the radiator fans? I'm thinking at the inlet of the engine, so regardless, the fans are operating to keep the entering water at the right temp. I'll be able to set the fan start temp for whatever I want, so that's not really an issue.

Pretty much done with the fuel system now. Just need to get a couple of things cleaned up and then wiring for the fuel pump.

I need to pull the motor again, I found out I'm missing a couple of bits that hold the throwout arm in place, not so good, so I'll get the motor yanked and hopefully that will be the last time till I take it apart for the final clean up and beautifying!!! Yes, AFTER it IS running!!!

Hi

Does your ECU have a fan control wire. If not I used a probe from http://www.daviescraig.com.au on my top radiator hose. If you go for an adjustable probe like I did, don't set the temperature too low.

Yep, the 034 ECU has a variable temp trigger. I'm looking online for a VDO ****pit style Temp guage too, I suppose I need to actually see it in front of me as I'm driving!

On the Eco, the switch was just prior the t-stat. What is the factory location? One caution, up high is good but not so high that if it ran a little low of coolant, you wouldnt know it was cooking. I went through a whole air pocket headache with mine in the factory spot because it was impossible to get bled past the t-stat.

If you havent already, look into the variable fan controllers. They usually include sender and ey'ting you need. What I thought was the shizz is the soft start and faster as you need it function. I never got around to upgrading to one. When my fans kicked on, it put a serious hurt on the electrics and made the Eco skip a beat. The soft start takes care of that.

Keep plugging away! I have to live vicariously through your project for the time being.

Have a look at factory fan switch positions, they are mostly half way down the radiator. If you have it in the top hose you run the risk of it coming on as soon as the engine is up to temperature, not when you need the extra cooling from the fans. IMO having the switch lower down, this temp will start to rise when the engine is running out of cool coolant which is when you want the fans on for the extra cooling...

I'm having 034 build a harness for me, I think it actually uses the stock H2O temp sensor so that is taken care of, and then I can just set what temp I want it to come on at.

Pulled the motor and tranny out for the last time. Wanted to make sure everything inside the clutch was buttoned up OK, found that I had forgotten to tighten the bolts on the driver side CV!!! Double checking is a good idea apparently....

Welded up the gaping holes where I cut the frame horns off at the torsion tube. Engine back in then wait till new harness and throttle cable arrive from 034...

Ordered this sucker today:

Hargett Precision Throttle Pedal

I think it is an excellent product for the money. I was planning on just building one myself, but at the rate I've been going I figured I better not mess around!!! I think I'll be building the actual pedal surface myself though, so it's exactly what I want. Check out the shifters they have too, pretty gorgeous.

Just need to figure out how to connect this with the stock VW 1.8t throttle cable now, some sort of extension I guess...

Jason

[Panelfantastic]

Is the 1.8 throttle push or pull? Can you run morse all the way with an adapter right at the throttle body?
I had to build a swing lever to convert mine from push to pull (buses are already that way but I had to reconfig most of it) and spent some time figuring out the geometry to get wot.
Are you sure you dont want to try DBW? Somebody needs to be a test case and tell me how hard it is.:devil:


Jeff-

[volkdent]

It's pull, I think it will be fairly easy and adjustable, but of course it's easy to say now!!!

DBW huh, sounds great!!! I gave that up so long ago, nobody makes big power using DBW it seems, plus its just another detail to keep me from getting done!!! I still have the pedal and throttle body if I feel like torturing myself though...

Dent,

Let us know how this works out. I'm sick of dicking around with the stock pedal trying to get WOT. Will you be using the stock brake/clutch pedal with this setup ?
Won't the original setup be 'in the way' of the new pedal ?

Panel,

Do you have any pics of the lever you created to increase the travel of the cable ?


Thanks,

Rob.

Well, it didn't actually work out so well. It turns out the quality control on the pedal's manufacturer has slipped way out of control. The breaks were not perpendicular, the hole tolerances were way off, there was 3/8ths of lateral slop at the pedal top. I emailed Mark Hargett and he agreed, so I'll be returning it. I think he designed it, but then has someone manufacture it for him. Sounds like he's going to be addressing the problems pronto., so it should be a good product again in the future. I'm going to return it, but not before I get all the dimensions down, modify it, and build one myself that works for the bug application. If I want then, I can buy his pedal covers, they do look pretty sweet. I'll copy that design if someone is interested.

Rob, if you go to the brake section, the thread "Let there be brakes", you'll see the pedal cluster I'm using.

Hi

OK you need to check for spark at the plugs, if no spark check for pulse at the coil and also check for pulse at the injectors. If you have spark, give it a drink of fuel down the manifold to see if it gets a result. Can you hear the fuel pump priming?

Most ECUs earth the fans to make them work.

As far as bleeding goes, is your header tank the highest point? On WBX I drilled a very, very tiny hole in the thermostat to allow the coolant to flow to both side of the thermostat, some thermostats have a ball check valve for this purpose. I was able to fill my WBX from my header tank and any air in the system would bleed to the top the header tank, then the overflow system would rid it of any air after few warm ups and cool downs.
