Mk1 16v Project

looking good !!!
by the way , your not working if there is no blood

Haha, yeah i'm hearing that. Seems to be that with cars, it doesn't matter what you are doing, you increase your risk of injury just because it's to do with an automobile!


Also, something else interesting... On saturday i went to Canberra in the big bad Caddy with the old man cause we were taking one of the 392 blocks down to Graeme Silk race engineering. Turns out he does Neal Bates' toyota rally car engines! Apart from a lot of other really trick drag racing engines, sprint car/ speed car engines. I had a look at his gear, and he has some really nice stuff and i also took a look at some engines he was currently machining/ building.

And to top that off, he has a brand new top-of-the-line Superflow engine dyno!. So i've decided i'm going to get him to do all the machine work and balancing on the 16v. He confessed that he does charge more than most engine builders, but i can tell he takes an interest and he also makes sure what leaves his workshop is exactly what the customer wants and up to his (very high) standards.

So when i've finished building the engine, i'm going to head down there so we can tune it on the dyno.

Dad and i are currently in the process of ordering some 5083 aluminium 50mm thick billets so that i can machine up a torque plate for the 16v aswell as one for the 392 engine.

Once i've made the torque plate i'll post some drawings for everyone.

I didn't realise, but a lot of people bore (or get bored) their blocks static with no tension. This is a really bad idea and is why some engines can be freshened up and still have bad leakdown from new. In some cases, the bore can distort up to 4 thou (0.10mm). Which is awful.

there's a phone numer you won't want to loose any time soon!

p.s. sorry I havn't got those number for you, I haven't been able to get them measured up very accurately.

My uncle gave me an oil cooler yesterday! It's off his march open wheel formula 2 car he had years ago. Really good quality aluminium cooler.



Also we're currently building a car trailer for his 914/6 currently being restored and for the Goof.. . So i'll post a couple of pics of it tomorrow. The main chassis is pretty much done and we welded the axle in this arvo. It's going to be a tilt type loading trailer but with no extension ramps, so it's pretty interesting.

Something else interesting.. Here's a pic of a standard Chrysler 392 hemi main cap (top) and a standard VW 16v main cap (bottom).



Yet another reason why VW engines are so bullet proof and you can extract such good horsepower from standard equipment..

[Valver.]

That's an interesting pic comparing main caps!! Thanks for sharing

Did some more work on the trailer on sunday. Silly enough (i should know better), i was welding in shorts. Got some SERIOUS ray burn on my leg. Won't be doing that again!

On saturday i machined some wheels for a guy who races V8 supercars in the fujitsu series who has the workshop next to my old man and mine. He needed some wheels with a square machined outer edge, so i threw them up on the CNC mill and machined them.



I removed all the water lines etc and pulled the radiator and a few other things out of the golf yesterday too. So as soon as i get a chance, the big bad goof is going on the hoist to have it's ticker removed..

Got my block back today from being acid cleaned, too. Now i have to de-flash it and then remove all the plugs so i can wet blast it and get it all smick to go to Graeme Silk gingerbeering to be bored to 1.9 and have the crank machined and everything balanced.



Got some more Goof stuff from the US too. I got a new golf ball gear knob, a new early euro shift boot, an original US Rabbit badge, a new 16v cam chain and a new 16v dipstick. Also coming is a full new gear linkage kit (16 bucks US!!!) and a full Prothane engine mount bush and suspension bush kit (70 bucks US!!!!!) I love Ebay..

[Jarred]

interesting that you've decided to go with the rabbit badge there. Personally, I think calling it a rabbit is weird, and I've always prefered Golf,, but that's just me.

I thought about getting poly suspension bushes but someone said they'd be too much for street usage. My suspension is firm enough as it is, for my daily. So for now I don't need to change anything, but I'd be interested to see how it goes....

[WABIT]

hey mate love the progress with the 16v, one question though

what are you using for a exhaust from the manifold down? headers or custom from the mani down? ect??

cheers

I'm doing the Rabbit badge because it's unusual and i like doing things just a little bit different. It is weird, yeah. That's another reason why i'm doing it. Plus i think the little bunny looks cool.

Poly bushes are very noisy for street use and can knock/bang a little sometimes so you're right, normal bushes are much prefered with good suspension to give you a well handling vehicle that is still reasonably smooth to drive. But hey, i don't care because i'm doing this mainly for competition.

-Oh, i also de-flashed my block today on the skirt webs. If anyone is interested in why you de-flash a block and wants some pics, i'll put a post up with some info etc, otherwise i'll leave it at that.

I'm using the standard 16v 4-2 manifold (ported and port matched to the head) with a 2-1 mandrel downpipe. From everything i've read the standard manifold makes the same power as extractors, depending on the setup, you may squeeze a few extra HP from extractors but $600+ for 3 or 4 HP seems a little pointless. I spoke to the guys at Techtonics and they said yeah don't worry about it unless you are pressed for room, and they sell the things.

Is the ABF mani the same as the KR one? If it is, and you're interested, when i get my downpipe made, i'll get 2 done. Glennboy at Central West Exhaust in town works magic with custom exhausts, he does a fantastic job and for a good price too.

Anyway, if you're interested let me know.

[WABIT]

hey

its all good ive actually got a 9A engine (k-jet) i have a manifold and the downpipe cut off at the flange to i can graft my custom exhaust i had on the 8v but im also getting a set of ashley racing extractors cheap!!! hehe

thank you for the heads up anyways mate and good setup on your exhaust system cant wait to see the finished product

[Golf Loon]

ABF ports are the same, but engine is 10mm taller.

[WABIT]

sorry i didnt quite get what you mean what was it again only kitdding mate

hahahahhaha

[Jarred]

yea What's all this engine de-flashing about. i'd be interested to know all the things you're doiong to your eng, and the reasons why,. it seems a prettty comprehensive rebuild... (of the eng)

[velly_16v_cab]

a 4 branch manifold for the exhaust will allow the car to breath much more freely.
It may seem alot of money to spend for little bhp return but the car drives and responds so much better.

The way to get the power out of a 16v is to allow it to breath.

just my 2cents worth

Fair enough. I'll go with what i have now and see about something different later on if i feel it would be an advantage..

Allowing the engine to breathe better is the way to get power out of anything .
