VW Golf track car coming along

[robbo927]

Hi All most of you would have scene my golf in the forsale section, however I have decided to keep her as she is part of me. Since my last post about her she has undergone more major changes.

Stage 1 (Completed)
Originally the 2,0 engine was pushing out 110HP at the wheels running a dtml webber 32/34 down draft, 4 speed box, full weight reduction (interior including dash gone) only one seat in the car/RPM 5 point racing harness. OMP strut braces front and rear, top of fire wall removed to enable cold air to actually get to the carbie, Holden VP break package, Simmex racing tyres. Facet Electronic fuel pump - car runs on 98 pump fuel, SPAX Racing Springs.

Stage 2 (Completed)
In the last month I have upgraded the carbie to a webber 34/36 DGV this has allowed me to run E85 Fuel (75-80% Ethanol) it has also meant that I have had to replace all the fuel lines with EFI/E85 compliant hoses, upgrade my facet electronic fuel pump to a carter black racing special. I am playing around with jets as its very grumpy from 0-4000rpm. Now has Golf GTI Big Break conversion, with new discs and Bendix DB401 Pads. Complete Audi genuine leather interior, SAAS Racing gauges including tacho, water, air/fuel, volts, fuel, oil temp and water temp gauges. At the top end of the rev range it really opens up. and fire extinguisher.

(Testing is being done at Willobank Raceway Test and Tune nights. Ran a 16.00 flat with out reving to 4000rpm and without tuning) and hard tyres

Stage 3 (underway)

Custom aluminum intake box with 50mm outlet with custom polished stainless steel intake pipe around engine and down past water washer bottle to K&N air filter pod (already fabricated just needing polishing

front wheel arches flared (done)

Then onto
Dyno tuning is to be completed in the next few weeks and I am expecting around 140HP - 150HP at the front wheels

Once the car has run somewhere around the 10-13 Sec quarter mile mark then Stage 4 will start.

Stage 4 (before Christmas)
Installations of my 2.0 ADY Fuel injected engine, 300cc injectors, E85 Fuel, Microtech ecu, Fuel Cell, PWR Radiator, PWR Oil Cooler and braided lines (already purchased), silicon hoses, Coil overs, front and rear sway bar package, SC14 Supercharger.

With around 140+ HP plus 30-40% power increase with the super charger I should be sub 10's on the quarter mile, this will mean Advan semi slicks for the front to help with traction. (my aim will be for 180-200HP) and sub 10 sec quarter mile times.

I'm not bragging but wanted to share my build as its a massive learning curve and constant tuning issues however a fun journey and I 'm looking forward to really turning some heads and having some fun.

I am seeking feedback from those whom have been there before as your knowledge is key to getting this right. I would also like to let everyone know that the air box system is something that my fabricator is considering doing for a price however $$ will depend on what carbie you have as the base plate needs to be made for each type of carbie - the upside and after some testing is that it allows direct cold air induction (not cheap crap) in from the front of the engine picking air up from either GTI head light or from the space in the front of your bumper. (This will be marketed as a Mad Dog Racing Product along with some other goodies we a re developing including out own sway kit, E85 conversion kits, dry ice kits etc..

Let me know your thoughts if you have any advice feel free to PM or post me about it.

Pictures will be posted once the polishing has be done in the next few weeks and some vinyl work has been done to the car.

Keen to see pictures.

Good luck with the project., I've always wanted to play around with E85.

One thing though, sub -10 second 1/4mile time? Is this a typo, or..?

[robbo927]

Thanks guys - sub 10 is the aim. But for the moment 10-13sec quarter

[robbo927]

As of this morning the carbie has been changed Standard primary main jet is 1.40mm changed upto 1.55mm. Secondary main jet changed to 1.50mm. Primary Idle is normally.55mm upgraded to .60mm and secondary idle is .50mm changed to .55mm

Unless this mk1 weighs 500kg with you in it, I dont see sub 10second quarters happening - you are going to need more than 400hp to get even close to 10 seconds.

There are lots of sub 10 drag builds for mk1's around (plenty on youtube) but they all have a lot of HP. I guess if you are really aiming for more than 400hp its do-able, but I'm going to go out on a limb and say never that much hp with an SC14 and a 2.0 8V.

Happy to be proved wrong though...

The stock standard mk1 golf weighs 810kg, my car has been completely stripped including all sound deadener, I have light weight 5 spoke rims which are 3kg each lighter than standard, the big break combo lighter than stock, the suspension is 7kg lighter than standard, the tyres are lighter than stock, the exhaust is a custom stainless exhaust system lighter than standard, the car was tuned this morning and had a dyno figure at the front wheels of 148hp atw. There is more weight reduction coming after some advice from Chris Mcganughy who has directe me on somersault more weight reduction via whole sores, side intrusion bars etc. the power to weight is good at the moment but will be better. With the rest of the sound intrusion weight reduction completed the car should be closer to 600kg. With a 148hp + sc14 or Mercedes m60 it will h e an additional 40% power. Getting it too 207.2hp atw. If I go with the US turbo system for $3.5k rather than sc setup it will be 396hp atw. Giving huge power to weight. Like I said this is a major development process and I mite even end up chopping the roof, replacing the front guards with fibreglass, bonnet as well. Replace all glass with plastic. The options are endless however the aim for the moment is too focus on getting to the 10-13 sec quarter. Then go bigger.

If a 1.8kjet turbo can run 10"s then a 2.0 can do better

[Jarred]

Which 1.8 kjet turbo ran 10's?

Last I heard of a car like that it was running 12's. (still a very respectable time)

Here's a video:

If you havn't seen this guys stuff before, it's pretty good. Have a look through the channel, good fun.

Anyways, this video is of a mk 1 polo (lighter than your average mk 1) with a 1.8l 16V turbo pushing ~700HP. It runs a 9.9s pass, and is basically a full blown drag car.

I don't want to discourage you from your project, but I think you'll need a little bit more under the hood if you want to get a 10sec pass, let alone a sub 10.

[Water Boy]

Good luck running tens.

Tim ran 12's in his Mk1. I think if it was easy to run 10's he would have done it 2 years ago.

The gap between 13-10secs is about $10,00+ and a **** load of work.
