Well its all finished and badcooky wanted to see so here she is.  Loose specs are:

Engine is pretty much a stock 80" Evo.  I have blended the heads a little but nothing more than what a home handyman would do.  Turbo is fixed at 10lbs boost which gives me 107hp at the rear wheel - I had it on the Dyno last week - its enough to light up the rear if I get careless - top speed is a rock solid 140mph with the current gearing. lol

 In the above; the charge tube is now matt black and basically so hard to see that its stealth.

I HATE the exhaust muffler but its all I had at the time so am making up some 2-2 short shot style pipes as I like the shotgun look.

Bere is the 'business' side of the engine.  All the fuel pumps/regulators etc are mounted low and behind the front spoiler.

If you have any questions just ask away

 

Nice job on mounting the turbo it looks great where it is. What pistons and comp are you running with the turbo

Hi...stock pistons and stock compression at 8.5:1
I had the jugs honed a year ago and dropped in a new set of rings, but that's about it.

Nice Mate. Well done. Nothing like a compressor to make life fun.

Thats cool man! Is that a steering dampener I can see?

Yes it is... I had a niggle/wobble when in some corners so thought a dampner would fix the issue - she can now go through a long sweeper at 160 and not miss a beat (not that I would ever ever do that of course). It's a unit off a GSXR1000 that I picked up on eBay for bugger all - I did look at the units made for Harley's but they all seemed like cheap chineese rubbish and cost $200!

I have the full install and fabrication in pictures.... It's really not a complicated setup and is easy to make; I do not have access to a machine shop so a home shed should have all the tools. Let me know and I can post it all up.

Consider yourself asked. Anything to do with a different build up will definately create some interest.

So post away.

Fire away please

Hi Matey...Yes its an Aerocharger unit. I had all the setup for a Garrett install but then the Aerocharger came up on Ebay so I could not resist. Its made the entire job so much easier to not have to worry about plumbing in Oil lines, Waste-gate and BOV. Its a little larger physically than the Garrett so will not fit behind the front air scoop like I originally planned, but thats fine; being on the left side of the bike no-one even seems to notice that its there....lol

The only caveat with it is that if you try to take them above 10psi (say 15psi-20psi) they will eventually chit themselves as they are just not designed for high boost applications. Having said that i was only going to run my Garrett at 5psi so to be able to hit 10 is frigging awesome.

Cruising at 100kph its making about 2-3psi boost so if you you give it a handful of throttle it will instantly accelerate to insane speeds very very quickly. At 80kph in town its still making 1-2psi so there is absolutely no turbo lag at all.

You have got to start looking for a turbo again as you will love it!....

Yeah its a little noisy...you know the variable vanes are working, but its only really noticable in the lower gears; once your on the highway or in 4th or 5th its no louder than any other unit i suppose.

Mines about 6 years old and i have no idea what the mileage on it is, but she seems solid enough.

I'm chewing though my new Tyres and my stock brakes are next cab off the rank to get tweaked as I find I'm using them way more than i used to..lol I have a copy of the Dyno run that I'll post later tonight.

Here is a copy of my current Advance curve (its the WOT one).  I used to run it at 35 degrees but someone mentioned that it was too high -  mind you she never pinged or gave me any grief.  I redid it to be on the safe side though.  I think I can re-program the ignition to have the Part Throttle curve activated by a switch so i may be able to set it up to run 35-40 degrees advance until she is boosting at 5psi or something (i have a small programable boost activated switch i can use).

 

 

Heres the Dyno chart....I'm buggered if I know whats wrong with the Torque Curve as it does not even cross over at 5200rpm. 

 

If your bike shop says to go back to points...then its time to find a new bike shop!

Yeah no problems...They are a piece of cake! (unforgiving if yah get it wrong though)

What year bike are you using as a framework?

Hey matey,  I would steer clear of a draw through system; even though they are simpler than a blow-through they went out of fashion in the 70's.  The main problem with them is they can be real bastards to start and the Turbo unit needs special seals so that it can withstand the fuel mix going through it.  A t least you do not have to worry too much about intercoolers and fuel pumps + rising rate regulators to match pressure to boost with a draw-through, although it still pays to have a small low pressure pump (say 2psi) to help keep the float bowl full under full boost.

 Any carb will do for a draw-through as well, although I would research it more as some carbs are better than others.  The issues I have with the stock Harley CV are that it continuely destroys the rubber membrane on the slider (I think its because boost comes on so fast that it really slams the unit upwards and stresses the rubber too much), I go through about 1 every 2 months and while I can still limp home when it goes, its not ideal. Dynoharley has the right idea in using an EFI bike as that solves a chitload of problems, although it does need a differnet set of skills to tune the bugger.

Can you tweak or program up the Ignition advance curve at all?  I have mine setup to add heaps of retard at 3000rpm which is when full boost is on to help keep the engine together.  Some ignition modules support two curves with them being automatically switchable (my one does, but I have not played with it yet – perhaps next summer)

 Hey…on the oil side of things I have some pictures of where to tap into the cases for the oil feed and return lines that I can post up if I can find them – they are not mine and I cannot remember where I got them from, but they are definitely Sporty centric.

 I’m waiting for winter to settle in and will then pull the heads as I recon they need an inspection at the very least and perhaps a light valve reseat; worst case will be new bushes for the rocker arms as I’m getting a fair bit of top end noise this year.

 You really really need to pull the cam cover at some point and ID what cams you have.  Having said that I know absolutely zip about Sporty Cams – now if it was a big twin then I could help.  I’m running an Andrews EV31 which is designed specifically for blower engines and can tell the difference between this one and the old Andrews EV35 that I started out with (the EV35 was bloody peaky, basically bugger all until 3000rpm and then the bike would take off like a two-stroke on steroids!)  At least the EV31 smooths things out across a wider rpm range.

For starts i would keep your compression stock.  Mine is standard at 8.5:1 static, although my calculator tells me I hit around 14.5:1  when under full boost which is 10lbs.  I am impressed that Dynoharley can run 11.5 static without an intercooler - bloody well done mate.  Upping the compression is something I have not thought of yet and may be worth a crack as i have not had any pinging issues to date - and i do have a set of spare Evo heads in the shed awaiting tweaking if I every get enough free time. 

My turbo is off the bike as we speak and should be landing in the USA this week to get serviced!  God I cannot wait to get it back!  I also have another Aerocharger turbo (that has been serviced) that I’m going to put up for sale as the air outlet port is at the wrong angle for my setup (you cannot ‘clock’ these units) – yes I could modify my mounting brackets and plumbing setup but it starts getting messy so I figure its easier in the long run to fix the old one instead.  Lesson to self – NEVER run the turbo at 20lbs even though its frigging insane on the power front as the unit is just not designed for it.

 

 

Heres the link to that Sporty oil line location. Its actually from another Sporty Turbo build which looks awesome.

On my install i have the exhaust input running in front of the front cylinder and the exhaust out of the turbo directly under it. So to protect the fuel pump, regulator (which are mounted in the base of the lower fairing) and to stop heat soaking back into the engine I have wrapped heat tape around the pipes that run across the front of the bike. It works bloody well too as you can basically touch the tape straight after a hard run and not burn yourself. I sprayed the tape with VHT paint after it was in position as it helps the hold its shape.

 Hey man, that looks like shitloads of fun!! Any chance of you uploading a video of it running? Would love to hear what it sounds like..
