500bhp, custom built turbo etc, home build!
Folk on here can't even get TB's and Superchargers working!!! It will go bang! I'll bet my jewish konk on it!
#500bhp in the original Mk Indy chassis is asking too much,
Unless he spends money on the diff it will be flat out at around 120-130mph, yeah it will get there really quick, but when it comes to a corner it will struggle. I've had one of the original indy chassis and you could see it flexing on track with just 120bhp.
Waste of money for me, if your going too spend that kind of money on a turbo set up then you may as well stick it in a better chassis.
Good luck to the guy anyway, having been there and done that with kitcars i now prefer something with a roof and comfy seats
Here's an update:
Checked the valve clearance and degreed the cams to 105in and 108ex. Cams will get tweaked on the dyno, but this should be a fair starting point.
Modified the clutch master cylinder from the bike handlebars and welded to a mounting plate. It gives the correct travel on the clutch, I'll probably have to add a bleed nipple to the top plate so that I can fill the reservoir to the top and not get air in the system.
Turbo mounting bracket.
It fits! Found a spot for the turbo, it's a bit snug. Uprated the chassis mounts, but the engine cradle is for a standard Hayabusa and doesn't look up to the job (see those end tabs ). So I'll be making a stronger cradle. There is also another engine support that will triangulate from the head of the engine. Manifold is going to be tricky... it's a bit tight in there.
That will be awful to drive. Normal busa engined ones are bad enough.
Turbo bikes are w**k too.
So god knows why he combined to two.
It won't spin the rears though, bikes cope fine with half the weight and half the contact patch.
Blatently gonna need a teflon covered passenger seat.
i love the crazyness of the idea
i hope someone on that forum told him first that it wouldnt be financially beneficial for him
Gaz, you are bonkers!
.....well done!
Here's my attempt at a turbo manifold. Needs cleaning, welding and porting.
I know that equal length runners would be better and a straighter drop into the collector, but space is tight and it's my first go at making one of these. It cost about £70 in materials... and 2 days grinding!
Small update... Not too much progress, but lots of head scratching.
Strengthened the engine mounting frame.
Started working on the exhaust. It's 3" from the turbo. Yes, it's going to be loud.
I decided to use the existing silencer and open it up to 3". Here's the original 2" pipe.
I cut and welded the perforated section to just under 3", so the 3" stainless fits tight over the top. It also means I can still repack the sliencer.
Exhaust finished
... tempted to make one of these for a sunday morning blast.
Pmsl! 99% of this forum couldn't tie their own shoe laces ffs!

Tacked the exhaust together today and ordered another turbo flange to make a side-exit exhaust like in the previous photo.
Next job is to make a plenum from this...
