Today, I fitted this carbon prop.



After putting both props on the scales the saving is a whopping 7.2kgs. That's 2 more than I though it would be. I then weighed my car.





Only 35.6 to go and then it's time for a t45 weld in cage and some proper chassis chopping to get even more out. This heavy 40kg CDS cage needs to go.

Once that's done....it's time for a a front splitter, some cusco diffs and a bosche motorsports ABS kit. I have a long to-do list but it's all fun. :)

I wouldn't mind knowing myself. Is there anything in particular you have found gave a significant weight reduction? I'm considering putting mine on a diet and wondered what have been the heaviest things you've removed?

1035 kgs is very impressive for an Evo - well done :)

Out of interest, roughly what do you think you've spent to get it to that weight?
I ask as am very interested in reducing my cars weight but whenever i do the math i just can't justify the expense.

1035,thats good going that!

Love to weigh mine..just for the geek factor to see what it was:lol:

Did you hire the scales or are they yours?

T45 cage should save a fair few kg...my SD cage is 40kg too.

As said on your other thread....no offence but the speeds you are hitting,the cage in your car doesnt look to be worth a [email protected] ..so good decision to junk it.

What did you pay for the prop

but that looks very different to mine tha noz.

Off the top of my head....and these aren't exact figures...just guesses.

FG doors - 65kgs
Run 1 carbon seat - 44
Lightweight loom and oem fuse box delete -12kgs
Carbon prop - 7
No dashboard - 10
Light wheels - 8
Carbon bonnet - 5
Carbon boot/spring delete and wing - 22
Titanium exhaust - 11
Lexan rear window - 3
Delete all interior, carpet, roof lining, back seats etc - 15?

There's 203kgs to be getting on with.

Standard 5RS = 1260 kgs - 203kgs = 1057kgs.

Not bad aye? That's quite a short list. Then you add the following:

Cage, big heavy turbo, heavy intercooler, heavy ass alcon brakes and discs, fuel pump system, dry sump system and all the high bhp supporting mods and people wonder why they can't get their high powered Evos under 1200kgs?

People think it's all in the chassis work...chopping it to bits and making it weak, but the truth is, the extra weight savings are in the sub 1kg items.

Reduce everything. Bumper bars, brackets...all those things you see that aren't making you faster...bin them or make them smaller. i've taken out around 100kgs of items that are under 1kg. That's where the hard work comes in though. It takes ages and it takes a lot of thinking. I wouldn't fancy paying a trader to do it put it that way...££££££...but if anyone wants to pay me to make a 960kg Evo then I'm very willing to help them out :lol:. I know exactly how to do it.

The cost isn't that much really. These prices aren't what I paid but....

FG doors 1200
Carbon prop 1400
Bonnet 1000
Boot 700
Carbon seat 600
Rear wing 800?
titanium exhaust 1400?
Rear Lexan window 190

There's £7290 for around 113kgs in that little list.

But as mentioned above, it's the other bits that you don't pay for but remove that mount up.

I advise anyone not to do this unless they want a track car only. They are really horrible on the road with the FG doors, dog box, no heater etc. Either leave it as a road car or do the full monty and strip the hell out of it.

1035,thats good going that!

I borrowed the scales off a mate but you can get your car weighed at MG Autos. Best to get a geo setup done at the same time too.

Yes there's some thick people who seem to think that if I add a cage it will weigh 1200kgs. Like a t45 cage is going to add 165 kgs? :crackup:

This CDS one is quite heavy to say there's not many bars. Unfortunately I can't just buy everything at once and I have to do it all bit by bit over the years.

The bolt in cage could be the difference between life and death over a car with no cage so worth way more than a [email protected] even though I value [email protected] quite a lot. :lol:

A mate of mine had a bad crash on the road once and his bolt-in cage it really saved his bacon despite not having a helmet on. They are way better than nothing but could be the difference between walking away with a few bruises and going to hospital. I need to get a hans device too.

Getting a weld-in cage will allow me to do all sorts of work on the chassis so it's on the cards, i'm just not sure when. If I had a spare 15k I could easily get the car down to 960kgs with a carbon roof, front and rear sub frames, deleting the lights etc. I have a huge list but I doubt I'll be spending that much anytime soon. It would be interesting to do it though, just because it's possible.

Well done kenny... i can remember you asking me how we did it ... its just a matter of covering every area .. now get chopping as weld in cage is about 45kg if i remember right .. but it takes over the strength, making you able to loose a lot more :smthumbup:D

Thanks for taking the time to reply, that's very helpful. I get what your saying about either stripping the car or not. I can imagine it to be an awful road car especially with the condition of our roads. I actually bought the car to use as a track car but never got round to sorting it. I'm hoping I can free up some thime this year to get stuck into it, I just need to make my mind up that it's definitely what i want to do with the car.

Cheers:thumbup:

Thanks from me too - it's hard to find any hard facts when it comes to reducing weight from these cars :smthumbup

How do you get the titanium exhaust through circuit noise tests, or are they more relaxed for sprints?
I had one on my last car (Rx7) and as light as it was (sub 4kg for a cat back) it was VERY loud.

Yep, you're the one who taught me the phrase "It all adds up". Many don't get that concept and just bolt on lighter things rather than searching for grams.

As for the cage, as per the comment at the top here, that's the plan batman. I'm just not sure when. Hopefully before I crash:lol:

I think you missed the comments above mate. It was on the custom cages site at 40kgs in t45. If that's true then there's no difference. Even if it's 45 kgs I'd be chopping bits out as the stiffness of a weld in cage would allow me to do much more work. As Barrie and I said, the car would actually lose weight with a t45 weld in.

Here's a custom cages example, albeit evo 4.

http://www.customcages.co.uk/Rollca...i&model=Lancer Evo 4&type=Int GrpN Multipoint

39kgs in CDS. I'm not sure if that's true but it sounds about right for a t45 version. You don't get to 1035kgs with a dry sump, OEM sub frames, standard roof etc by adding weight. That's no how my mind works. Everything that goes back on must be lighter, and if it isn't, you have to find it somewhere else. Some won't believe it but 960 kgs is possible, and that's without chopping it to bits so much it's no longer an evo.

I'd need a rs 1 anyway I bought 1 years ago on here in group buy from torqueline but they don't do them now
Driveshaft shop sell them via Ross W mate.

You're welcome and that's what you need mate. Time. It takes soooo long working on the tiny bits, AND then together with bigger projects on the car, it can literally make you fed up. Then you get it on the scales and you're disappointed. :lol: The worst part is the loom. I knew nothing about wiring and had to teach myself how to do it. It takes some guts to make that first cut. :lol: If I were to build another for someone I'd ask them to provide me with a shell. I'd then bang in a weld in cage and get chopping. Then I'd only bolt things back on that are ultra light.

I fitted 2 simons silencers from here:

http://www.jetex.co.uk/custom-exhaust-parts/

I ought to have just fitted one long one but I'm currently looking into getting a long titanium silencer and downpipe.

Love that carbon propshaft!! pure porn :handsup:

:smthumbup
It was so much easier to fit. That's what's good about making a car like this. All the bolts undo easily, everything has easy access compared to an standard car and all the parts are light and easy to remove bar the gearbox and engine, but even for that, we have....a solution:

If the luxury was there to dedicate full weeks on the car, I'd get stuck in tomorrow! That's my only concern, starting and end up doing a few hours here and there every other week! I've got a spare unit now and think I'm going to fit a 2 post lift, it'll make life much easier.

I did the same with my old Escort rs turbo. I cut all of the MFI engine management out and wired in the Fiesta Turbo EFI management. It's surprising how many wires you remove and the weight of the stuff. The Fiesta management that replaced it was a handful of sensors and an ECU, a fraction of the weight! No distributor, metering unit, even the fuel pump was a good LB lighter lol. At the time, I had a haynes manual and not a vast amount of self taught experience. It was a challenge of ups and downs in the rain and the snow but I got there in the end. :lol:

I'm yet to take an evo apart though, I'm sure I'll manage.

The 2 poster will certainly speed things up. I did mine in a small garage and no ramp. Right pain in the arse to be honest. With a 2 poster I'd be able to strip and lighten a chassis in no tim. That's the easy bit. It's that invisible 100kgs that's the difficult bit. I know of a very fast TA car that has a light rear sub frame, carbon doors, carbon prop, carbon wings, carbon bonnet and boot, ali roof and all sorts of other things. When you look at it it appears to be totally stripped but weighs 1220 kgs. :eek:

Kenny who's make is that prop if you don't maybe me asking?

Thanks
I don't think they make them any more. I hope they start making them again.

Kenny, I have a bare 5RS shell that I have every intention of fitting a weld in cage to.
Since now is the time to remove the heavy bits, what are those bits if you would care to share?

Email me if you want to keep it a bit secretive. Cheers
