The 1.3 Turbo Battle####

It seems that andy grey (H701) is wanting to get into making parts and Im very happy for him to do so tbh
Been making parts for years man, just havent been on the MSC that long to share it all before, although Micra stuff is relatively new, but after everyone had a pussy fit after I copied, although badly, a manifold I tend to stay quiet. Part of the less stess part of things
 
Lol, make it yourself Chris!! you have enough tools!

Im good also mate, know what you mean about the relaxed thing (and I too have a good girl).

Im sure you have Andy... I cant say I saw anything about a manifold so I wont comment :) I think you should buy NodSpeed, yours for £10k (including £5k of stock :D )

You have 5k stock... Bollocks

Started off playing with BMW's although its a saturated market

Not hanging up your coat are you?

The manifold looked bait. **** was told outright. Problem solved.

I wish mate, I need a decent welder.

Ah fantastic. Well ur both welcome down at some point. We have a spare room for you to inhabit.
 
Not if you understand the force input to the joints eh :) braces work almost 100% in compression
You have to think of the twist motion too developed in corners, if the brace is allowed to articulate, like the one that appeared from some other place (I forget where) you're not bracing anything, just giving the chassis an arc to move on :)

Not sure I agree with this tbh.

How can you not?
It's like anti roll bars and solid axles. The 2 designs are completely different
Hard corner for example, outside wheel is pushing up on the chassis
Inside wheel pulling down
Creating a twisting motion. If a brace is bolted it allows the strut tops to move independently but limited, loosely like an arb
If the brace is completely solid they can't without stretching or contracting the brace like a solid axle. Another comparative item is a roll cage, welded cages are much better for chassis rigidity than bolted ones because (other than bolt failure and safety) allow articulation

Either way the effect is dramatically reduced in cars like ours with the strut tops so close to the bulkhead, it acts like a brace already. An mx5 on the other hand is another story

i disagree. The only way to stop the chassis twist is triangulation which a strut brace is not. All a brace will every do is fix the distance between the strut tops, it will not stop them moving vertically, this is regardless of whether the joints are fixed or hinged. The reason I made NodSpeed front braces fixed was to keep costs low and manufacture simple. If you draw a simplified free body diagram I think you will understand where you are going wrong :)
 
I was wondering about the triangle ones on the k12. I am thinking of having my front panel off an replacing with... erm.. more unflexible tubing. does it need to be a perfect triangle.. like erm does it all have to be connected at each point. or can you meet the front panel front the tower at two points? EDIT also I have suggested the front idea as it seems connecting to the firewall would be a bit flimsy. or does that defeat the object? also looking in to this

Depends on design, they do aid even in the vertical motion
In your design the vertical twist isnt countered as it asks the main bar to act as a torsion bar through small transfer points which will flex at the same rate

The wider box/oval tube braces cant twist in the same way, they' have wider more direct transfer points, higher twist resistance, resulting in a proper bracing between the 2 points. If they were bolted, then its all to waste, which was the original point made lets not forget :)

They're not a be all and end all, but we're talking strut braces only here

If we're talking complete twist motion bracing, then we're onto completely different braces.
H701 has an inner wing brace for that, similar to Chris' photo above to combat twist
I'm also planning an X brace which joins the lower wishbone mounts to the strut tops, but its proving difficult
 
Closest to front up top should really be a bleed nipple to block.

So, I left for a while, needed to sort more important stuff and fell out of love with the car. The car is facing its next reinvention. I know people people have got better **** to look at, but I was wondering would anyone be interested in me to start blogging the car and the build? Do I start a new one? or shall i just not bother? I don't really feel I can contribute much anymore as my **** isn't wild or maths driven. Give me a heads up please. yerrpppp

Do it.
 
My hope is to build the car now in preparation to compete eventually. No idea on time scale, but I want to use the car, and develop it.
 
Yeah I struggle with Paul. All that technical with the same result, I take the piss but I am jealous of his technical understanding of it all
 
On a serious note...The car has had a lot of focus over the last few weeks. The car is being a bit more serious, the attitude of 'it'll do' is not good enough any more and is being rid of. I have gone for a proper suspension set-up designed for the Micra, and is worth every penny.

Ignore the snapped driveshaft!

I visited the go to man, Matt @ Humphris Oxford - http://www.humphrisoxford.co.uk/rally/ for a package which is going to take the car to the next level. Contact @mph if you want to contact him on the forum. I would say just ring him, its easier!

So, where to start! The suspension, I have run through a couple of revisions of suspension set-up, and to be honest corsa/polo/lowering spring...just not worth it. Want it done properly, buy the right kit. Proper droop front and back (makes a huge difference) and great flexibility with dampening settings. Appropriately chosen spring rates for car (250lb/" front, 100lb/" rear), matt had a chat with me and what I want to do with the car, even taking in account for the extra weight of the mods up front. No fab work, perfectly fit the car and had these fantastic camber adjustment metal inserts for identical camber both sides.
Also, to compliment these I purchased some poly top mounts and metal bearings for a smooth action. bloody fantastic, the steering is so light and dare I say it, lessens the LSDs effects.

I grabbed some nismo bushed trailing arms, poly gearbox and engine mounts (side and back). I recently installed lower arm Nismo bushes and that made a great feel to the car, with the addition of the rest of the kit, the car feels tight as hell.
The uprated ARBs and their poly mounts mentioned above, counteract the soft suspension and maximise grip but kill that boaty feel. I never believed @pollyp @Enuo @h701micra (no preference to order lol) but Jesus they were right. This stance'd rock solid feel I was running like many others here is just silly. To compliment the rear ARB I got some fully adjustable linkage and enables me to make on the fly changes whilst the car is on the floor. Great for when we hit the track!

As you know I previously installed a front lower strut bar, I complimented it with an upper and it just added to the cornering feel. However under inspection, like @Noddie said (excuse me if I am wrong), it may be beneficial to triangulate it for a more solid strut. She moves a bit, but not too much. I will hopefully be adding under wing bracing to get those side tight too.

Finally, the caster kit... I rave about it... great turn in and makes the car feel so nippy! I grabbed myself a few second hand bargains from Humphris too, hydro handbrake, brake bias adjuster.

The roll cage is nearly in as well! New seats and 6 point harnesses. Got to love the safety kit! Oh fire ext kit and electric master cut off!

This whole update is what the car was missing. Its transformed the car and kills some time to my sprint courses times... private roads of course. I really feel the car is competitive now, and I now plan to use it for that. Money bloody well spent. Regarding the suspension, polos just don't compete and nor do the corsas; corsa coilovers are a maybe when machining a shock shaft extension with added bump stop in-between, but still don't get anywhere near these. *there are other suspension set-ups to buy I haven't tried them all...but to be honest, not many are designed specifically for the Micra*

I am going to breathing some new life in to the car and I hope to get some footage. It may not keep up with the big boys on the straights, but the corners they may have issues. Bigger turbo, more power, bigger brakes, lightweight, stiffer, safer, stay tuned.
