This is such a brilliant thread. Really enjoying the updates!
Thanks, Well it's in one piece! And oh my is it good now, it Drives beautifully.

Overlay with the last run where it made 113. With the air filter on.
Was an interesting day on the Dyno. Messing with the cam timing. Interestingly, advancing the exhaust smoothed out the dips in the torque curve quite abit. We were wondering if it might benefit from a 4-2-1 manifold instead of the 4-1.
The 2 big takeaways, were it needed longer runners. These were worth 5bhp
And it's really sensitive to cold air. Get the inlet temps down from the 40c to the 20s was worth around another 4/5 bhp. Which in this car I think you can actually feel. So I'm going to have to make some kind of airbox. And feed it from the outside world.
I'm well chuffed tho. It's so good now, it's just dried up enough for me to take it for. 30min spun before tea. And it's like a totally different car. It's not even that flat below 4k I guess it being so light it it still got som go.
Just listen to how good it sounds, now way better than bike engine

It would be nice to get rid of the dip just after 5.5k.
It would, but honestly you don't feel it. We did mess around with smoothing it out but nothing really touched it apart from the exhaust cam but start to kill power when we went further. Guy thinks it's likely a resonance in the pulses. Definitely be interesting to try a 421 and see if that smooths it out.

421 manifold and maybe even staggered lengths on the velocity stacks could help to smoothen it out. Tends to smoothen the peaks and raise the dips.

I've got to be honest I've struggled to gel with the fury abit. It's a car I've always been interested in but owning and driving it it it's just been abit too compromised for me.
But I have seen the potential. And there's alot I'd do different it I built one from scratch. ( I know your all thinking 'go on then!')
Today is the first day its starting to really click. The extra power let's you steer it on throttle. The suspension feels planted now. It's not rattling and vibrating like it's about to fall apart. Don't get me wrong it's not refined in anyway (bar heated seats
) but its making upfor it now . And I'm starting to get used to how it feels sat on the rear axle. And my god the sound. It sounds like something from a 1960s targa Florio. Little morning run out to c&m with my mates. The fury get so much attention it's on a par with the 205 at petrol station s for being accosted. But at meets it on its own level. There always someone hanging around it. Good job I like the attention
This tickled me
Couple of better ones of the side vents I think there pretty neat and follows the lines

Had too cook my own father's day picarnha
All tucked up for bed
Got lots of motivation to get more done now, and get out in it more! Watch this space

Great work! I've really enjoyed watching this come together and the latest round of modifications have really done the trick, it looks a great package now!
With regards the dip in the torque curve my first port of call here would be exhaust manifold, it would be worth going through the motions of calculating out the ideal runner sizes and collector sizes for a 4-2-1 and see if that will ever package...... or forget about it and just drive it as it's got some serious power/weight now

exactly that im really not too worried about the dip its more out of interest! you cant feel it in the drivers seat. a proper cold air box, would be far more effective ill be able to feel 5hp difference. . will hopefully quieten down the intake as while its lovely but its bloody loud on full chat at the moment.

and the chap i borrowed the trailer from had an escort quick rack sat on the floor of the garage. which i need to go and buy off him
never ending with me i know ! i like the look of this, the snorkel position allows me to use the existing cold air feed from the front so packaging wise it would be neat. i think i can mount it to clear the steering rack. however the wheel arch guard is half way through no1's intake so would need some fairly major cutting. eye watering price, but it does look well made.

open to any suggestions, ill take some photos tonight so you guys can see what I'm working with packaging wise
heres one for starters, the red arrow is the steering rack its about 10mm below the no4 intake now, the terrible red box drawing is the current arch guard. i can take about 50mm out of the corner. which gives me some more space for a custom box. I'm also thinking i could make a entirely new arch liner that follows the wheel shape to get more room. but it would need to be fitted to the chassis instead of the lift up bonnet. maybe i could utilse a lotus 7 cycle wing and modify it to fit the chassis
This is what i'm working with, abit more space than I thought so I think I could probably make that revere one work. But not at that price. Think I need to start stockpiling card board and sit down with a few beers. Draw up a box.
Any suggestions are more than welcome.

Been working on the airbox, came up with this design that was abit too low. And slightly off on the column.
So I've tweaked it and tested it again tonight and I think it's close enough to send off to cuts some metal. We can then massage it on the car to get it perfect. It's really tight on the steering rack. But I think there's enough room as the end is near enough solid mounted.
This is the V2 design. Shame there's not more space as I could have used a panel filter. I think I'm going to fit an inline 'cda' style airbox. Above the rocker arm, so I can keep using the ram air funnel behind the grill

Beautiful bit of CAD (Cardboard Aided Design) there! Looking forward to seeing the final version.
Can't beat the cardboard Looking forward to seeing the final version.
. to be fair im hoping it knocks some DB's off as it is seriously loud at the moment but its all induction noise. 
I completely forgot I've also fitted this 2.2 or 2.4 turn quick rack. It was the over 3 turns. So taken abitnof getting used to be it's really nice not having to shift my hands even on the tightest turns.
Like everything on the fury, it's was easy Todo. Took me longer to measure and swap the tie rods over that were different to the ones on the car. The wheel is slightly off, so needs the alignment checking although I was very careful to find the center of the rack. But had the same issue when I did the bushes. The must be a minor difference in where it sits left to right.
Also I wasn't going to post any of these because of the wind noise. I need to go out with the foam thing on, or get a remote mic. But gives you an idea of how good she sounds!
Seriously considering booking a track day for it now . Especially as I know I can use the trailer for not alot.
