I need a Stock (OEM) Carbie Rad.... any condition as long as it's straight. Please PM me or Email gacodling@hotmail.com Thanks Guys and Girls Cheers G

Took a little trip to Hel and back this morning ..... HEL performance that is lol

Some more pic's of the packaging of the VelocityShack turbo system

I have to be honest here , I was given one of these chinese headers , the one I had was flanged for a T3 , not a turbo I would use on a BB personally and yes the welding was tidy but after looking at it for a while and putting it on a flow bench and looking at it some more I put it in the best place I could think of.... in the scrap bin.... If anyone wants it I think its still there , would make a good doorstop or fishing weight. Looking good Graham. I'll be using this cheap Chinese thing to begin with . Welds etc. are OK but the design is probably catastrophic flow wise. I'll see if it will make 200 whp :icon_think:

Finished !!!!! two customers turbo exhaust systems completed, one carbie , one Fi , both for single right side tail pipe (muffler)

Yes... would have to look into the pricing and shipping , Carbie and Fi ? cheers Graham

Interesting trip to the machine shop and a pic of VelocityShack

Some more pics...............

Ditto. A ZX-14 is NOT in my future. Yep, why spend 14 - 15k on something ugly when I can spend a whole lot less on something I love. With the money I have spent on P1200 and the turbo project I could have bought several 14's , but why would I want to ???????

Been very busy in the shop.....................

Productive day in the workshop, started fabricating up a carbie plenum. Tried out my new flaring tool the make the plenum stacks.

Few new pic's of the bird shop. I mean VelocityShack

With the turbo cars I normaly work with there is two schools of though , we either fit a small turbos that spool at 1500- 2000 rpm and gives a low level of boost across the rev range allowing a smooth increase in power without lag or we build the big horse power motors that spool at 4000-5000 rpm and the power comes in like a train hitting you in the back. personaly for road I would perfer the first option. Attached are a couple of pic's of a car I have just finished for a customer, This uses a Turbo dynamics RCM450 hybrid the car weighs 1060kgs and is making over 550bhp from 2.1 L motor

Give or take a few mm it 500mm from the turbo port to the y peice 500m from the y peice to the start of the muffler and the muffler on my turbo bike is 500mm long.

3" is too big.... Don't think so. Square root error. Well... now with the port numbers I can say yes... 3" is too big. 2.5" would be best (for 48mm)... biggest I would recommend is 2.75". For what he states here.... Gt25r and GT28r ( not the GT28RS ) both have 48mm exhaust ports, the ID of the exhaust is 50mm . So the flow rate thought the turbine and exhaust port is less than the choked flow capacity of the exhaust. And the increase in pipe Dia would not do the torque figures any favours. But... 2.5 Might even be to big, if there is not sufficient length... and there's a whole lot more too it....... like, what is the length of the collector pipe ? 48mm is the max Dia of the port not taking in to consideration the loss of flow area taken up by the turbine blades and shaft .

Gt25r and GT28r ( not the GT28RS ) both have 48mm exhaust ports, the ID of the exhaust is 50mm . So the flow rate thought the turbine and exhaust port is less than the choked flow capacity of the exhaust. And the increase in pipe Dia would not do the torque figures any favours. Bear in mind though that as the exhaust leaves the turbo it begins to expand almost immediately and benefits from the dump pipe -- 4-6% increase in power, so I can see why Stan wants the larger pipes. On the other hand, I can also see how that complexity of fabrication would be a challenge for a small start-up. But surely for a road bike that will mainly be ridden off boost the loss of torque from the bottom end would not be worth the gains at the top end? We are mainly looking at an entry level kit that will be running a max of 200bhp to give all round good road manners. We can fabricate pretty much anything if that’s what someone wants. I need to keep my eye on the ball with the basic kit and not get too carried away with the exciting stuff. Have a look at any of the picture of the blue bike that is the pipe and it fits straight to the aftermarket Art pro 2 slip-ons I did it this way so anyone who has already got slip-ons and wanted to use one or both could do so.

Hi Buddy. I take it you approve.........

Packaging a 3" pipe out of the turbo would be very hard and I can't see any tangible benefits to doing so. The choke point of the exhaust system as spec'ed is the turbo body it's self not the exhaust. Any of the turbo’s we have spec’ed for road use would not achieve choked flow with the exhaust as spec’ed. Fitting of a GT3071R which is the biggest turbo that could be fitted to our header would require the fitting of a drag / dump pipe setup for race use but could still have to road system fitted with the boost tuned down to reasonable level for road . Cheers Graham

Sleeper look

Sorry I really should type with my glasses on when I'm reading from my hand written notes. LOL I have edited it now , the 12 in the wrong flange as well , the GT1548 is the smallest one with the right flange. Thanks for pointing that out. Cheers Graham

Not necessarily, if you get the basic kit with an upgrade Gt2252 with the 4-5 psi actuator the bike with run nicely at the 4-5 psi. later the 0.075" head gasket could be fitted along with an intercooler or water injection and the boost could be safely turned up with a boost controller to around 240wbhp.

The Velocity Shack Turbo kit for the Blackbird I would just first like to point out that the names Velocity Shack , Velocityshack.co.uk and Velocityshack.com are owned by myself ,Graham Codling (grahamcuk) and are not involved with, affiliated to or other way connected to any company , person or body using the word Velocity in there name or title. So this is how the song sheet will go......................... From prices will be posted ASAP... Very shortly there with be available a new Turbo kit for the Blackbird. Kits will be available for Carbie, early Fi and late model Fi and can be supplied as full kits or part by part and with or without turbo, so you can source your own new or second hand locally. All kits will be built to order only and due to the number of option available across the model range will be spec'ed and price individually. Any kit can be upgraded to the top spec by adding in the relevant parts. The Kit will be sold in the US, Canada and South America though HankXXX, (my partner in this venture) and myself in the UK and EU. Hank and I have been working on this for some time, Hank has worked with CP in the development of a Turbo spec piston for the Blackbird and combining them with the stock length Carrillo rods and the 0.075" Cometic head gasket or using the 2mm shorter rod with a stock thickness Cometic head gasket makes of a very robust bottom end. Note: All kits will require a small amount of additional modifications to the bike at the time of fitting. Clear instruction will be give on what is required for each kit. The turbo supplied with a kit will be adjusted for the application, kits supplied without a turbo will be supplied with instructions on how to clock and fit the unit. Entry level Priced from TBA A basic low pressure kit that will make around 180-190 bhp I will require the fitting of a 0.075" head gasket. Can be supplied with the Garrett T15 or the better GT15 turbo, non-intercooled and running 4-5 psi of boost and should have almost no lag. Power commander supplied on Fi models Supplied with clutch spring upgrade. Fast road Priced from TBA 6- 10 psi kit. Will require the fitting of a 0.075" head gasket. (Supplied with kit). Can be supplied with Garrett T25, GT2252 turbo or GT25R this setup is intercooled and will make around 190 -250 bhp. Supplied with clutch spring upgrade, lock up clutch supplied as an option. Power commander supplied on Fi models Extreme Road / Race Priced from TBA 10 psi plus kit. Will require the fitting of CP Turbo spec piston and combining them with the stock length Carrillo rods and the 0.075" head gasket or using the 2mm shorter rod with a stock thickness head gasket. Kit can be supplied with Garrett GT28R turbo. Lockup clutch supplied with kit Note: The fitting of an extended Swingarm is recommended. Please read and understand this: Turbocharging any engine increases the stress on the motor, we have taken every care to tailor each level of kit and put in the safe guards for each level of kit. We except no responsibility for failure to fit the kit correctly , observe the safe guards or ride the bike within the limits set out for that level of kit which may result in damage to the motor, bike or rider. You have been warned!!!! P.S we except no responsibility for how much fun you will have upsetting 14 and Busa owners

As I have had a number of people ask I am looking into a very Basic low pressure kit that will make around 180-190 bhp that not will require the headgasket fitment using a T15 or GT15 turbo, it will be a non-intercooled and run 4-5 psi boost and should have almost no lag. More detail soon on the fast road and Extreme kits HankXXX and I are working on .......... Graham
