Hello!! Well some kind of traction control would be nice! But the grip problem isn´t a big deal if the tarmac is fine. The time where so bad I rather not say it....
The topspeed: 137km/h (201m)
60 foot: 3.1sec
I will make much better next year!! I hope I will get some trackday time in it next year too. It´s almoste to cold up here in sweden now to drive a open vehicle.

What was your best time on the track?

Racelogic sells aftermarket traction control... comes with launch control build in too... pretty nice, I guess it would make a lot of difference on your beast.. it's expensive though..

Hi!! Hmm. Yes I know. because there have been more then 2200 downloads in two days, my webhotel decided that I´ve passed the downlload limit on this file..
If you want to see the film, you can visit my site and download it from there. www.mride.se

A real hardtop on the T42 trike!! Just a photoshop picture but I like it VERY much, and perhaps I have to make one next vinter.

After the paintjob and striping I have started to mount it together.

Hi Micke:

Did you primer/paint the inside of the bodywork first? I am almost ready to paint my locost but cannot figure out if I need to paint inside of the fiberglass.

Oh, the the bodywork came out very, very nice. Well done man!

THANKS!!!!! I´m glad you guys like it!!

I primed and painted the inside of some "not every" panel first. And after that I took the outside. less masking!
You doesn´t need to paint the inside of the fiberglass if you don´t want to. If the raw fiberglass is exposed to UV-light for a long time the polyester will change color and turn crisp and fragile... One layer of paint will privent that. But the question is how much sunlight will come in there? Probably it will take more then 15years before it happens.. But better safe then sorry.

THANKS !!!! To bad I can´t afford to build the carbonfibre hardtop right now... I think too that the T42 looks awsome with it!!

I have two new short video clips on my websight- You are all welcome to take a look!! www.mride.se

You'dd better secure that roof very good!!!!
It's a bloody wing and the air trap near the top of the front shield will form a perfect leading edge!!

.........it looks VERY neat though

Thanks!! Yes, you have a point there about the roof. But I don´t think that the lift on the roof section will be a problem. Aerodynamic lift is often generated by negativ pressure zones and turbulens.
If you have a large surface where the airstreem goes only one direction, and have nowhere else to go but over it. The lift effekt will be very powerful - like a airplane wing.
The T42 roof design is very narrow- only about 75cm. Most likely there will be a high pressure zone in the front of the window and upp till the highest point of the roof and goes over to a slightly low presure zone right over the passenger. And because of that the body continues after the roof shape, there will not be turbulens over the roof. The window shape will only push perhaps about 30% of the comming air over the roof and the rest out on the sides. The low pressure zone over the passenger will suck in some of the side streems and fill it out, which will reduce the lift over the passenger.
The front airvent scoop on the roof will "slice" the air (like cheese). This "slicing" will not generate lift, but it will add air pressure inside the cabin, and high cabin pressure will pop the roof off if the pressure is to high. I will mount a air lock so I can close the scoop. But if you build a air intake you MUST build a air outlet, to prevent this high cabin pressure and make a good ventilation.
I´m perhaps not a trained aerodynamic engineer, but I have been in contact with one and disscussed the roof design. And I think the roof will make the T42 trike faster in speeds over 200km/h - cause of less drag of cockpit turbulens as a open vehicle..

I hope you understand me and my swenglish

Hi Micke,

I'm by no means a aerodynamic specialist either but from the moment air is moved over a surface the pressure will drop,or explained in another way,will create lift.
I'm not worried by the air that will be deflected by the windshield but the undeflected air that will meet the front,or leading edge,of the curved roof.
75 cm doesn't seem much but a wing section of 75 cm wide and of chord of over 1 meter (lenght of roof) will produce a significant amount of lift at speeds of 200 kmph!!!!
Your airscoop will have to be of excelent design to transport all the air that is gathered at the intake at high speeds or it will form a buffer and this buffer will be compressed into a near perfect leading edge.
Most lift is created in the first quarter of the foil and if it's true that the flowing airstream will follow the roof almost till the end of the roof,it will only create more lift.
I hope I'm completely wrong on this (have been before) and that the roof stays on!!

Dont,by any means,let my opinion prevent you from building that roof and test it!!

cheers,

cita

Vetsanding and polishing the paint.

Hella 2" projektor and 3" highbeams





Fram a solid aluminium axel a CNC macin made the houings from my drawing.




The final finish.


ScothBright fabric makes the "brushed" finish. SUPERB!!






Front wheels newly painted. Really cool!!

Hej Micke,
it's looking awesome! Also an excelent choice of colour; very classy.

Is the front part of your headlight an original Hella part (the silver part with the grooves)? I've been trying to find something similar for my car, but haven't been able to find them. So now I have ordinary 5 3/4" light...

That looks amazing now it is painted Micke!

You must be very proud! Nice colour by the way.

I take it you decided against the bare carbon fibre look in the end?
