Agree with brad.....
Next to no lag in the brick (Old Turbo)
Squeeze in any gear and by 3000RPM its all happening...

My main difference, if that i dont have that 5th gear, so i'm sitting on boost on the freeway (3psi @110) - Bonus is incredible overtaking potential !

No-one expects a mini to acellerate from 90Kph to 150 in the time it takes to pass them !

I'm addicted to my little boost pig now.... even the bike doesnt have that power building rush that only a turbo can give ....

Nice....

The car must be under a bit of stress boosting on the hwy wouldnt it?
I havent owned a little turbo car but my falcon runs a 2400 high stall with a lock up convertor and boosts at 2000rpm but it isnt boosting on the freeway. Its a 700hp roller bearing turbo. It sits at about 2100 I think.

I cant wait to join the turbo mini brigade! Im in for a lot of fun I think.

Ok 13secondmini that sounds like the way to go. I really do need to get myself a front cut and get started.

Has the conversion caused any handling problems? I would have thought that tourque stear would be a major issue? Does your car want to change lanes everytime it hits boost?

At the moment the car is very well setup for track racing,, took it to wakefield park raceway a few months back and the car performed great. Very neutral in the corners,, bit of over steer is easilly fixed by giving the accelerator pedal a hit and the front comes around... had it 4 wheel drifting along the sweeping corner at the top of the track,, did not feel like i could lose it....

On the road it is sitting to low at the front and is giving me nearly 5 degrees negative camber....This will be fixed in the next 2 weeks as im fitting new cones and hi-los. At the moment it is riding on the bump stops so once that is fixed i will let you know.

At the moment it does get a bit torque steery if i run hi boost (12psi) and the rd is bumpy. If the road is flat and no slants then i can give it 100% throttle and it will go straight with some wheel spin in 2nd.

Well guys bit the bullet regarding the gearchange. Manufactured the replacement arm today. Was going to use parts off the original arm but realised that it was made out of aluminium so no go so completely new arm out of steel.

Brad good to know roughly what kind of power I should get out of the stock setup. I can handle 130bhp. And as you have demonstrated plenty of room for improvement.

Anyway here is a pic of the gearchange arm. I have a little while to go but hopefully I can finish it off tomorrow.



The arm itself

Matt you really are a clever dick..you dont look it

...but there is definately something between those ears

Brad....I have watched a lot of "racing cars" up close and personal at WP over the years....and your Clubby just went like a jet...very stable under cornering.....you can probably knock at least 3 degrees of camber off with no ill effect

At the moment it does get a bit torque steery if i run hi boost (12psi) and the rd is bumpy.

The torque steer I observed on the straight looked manageable and maybe even a little fun....no doubt you have learned to drive anticipating what comes next.....shouldn't be a problem

Hey Brad,

Does you 4EFTE run any traction control device - like the Toyota viscous LSD or any other traction control?

I guess if you changed your computer you could introduce traction control and launch control using this device.

Regards,
Andrew

nah mate i dont think any starlet ever came out with traction control,, some had abs, not sure if you could transfer that to a mini??

I have pretty much finished the new linkage today. Needs to be fully welded up and the excess cut off where necessary. But overall pretty much done.



and in place



Cheers

Nice work minstar. Will this cause any leverage problems and hence gear selection issues? I would have thought it would at least make it harder to select a gear! Good luck with it keep us updated.

13secondmini: It really does sound awesome, a mini that can keep up with the best of the latest performance cars in a straight line as well as round a bend, all the while being reliable.

Minster, yeah I know what your saying. I based the arm on the original arm which while working off the pivot point also slopes down quite radically I'll see if I can get a photo of the original arm so you can see what I mean. Also it moves the arm under light finger pressure so I think this should be a problem for the cable...

Here we go: Now the arm pointing downards in the picture slopes downwards from the ring in the middle roughly 60mm my arm is slightly flatter.

Matt you cheeky bugger - are you at home (flexi-day I presume?)

Now - about that alternator...........

Andrew

Sounds like you have it sorted minstar. Are you going to be able to set up the cables at the right length so that it moves into the correct position? It wouldnt take much to not select a gear correctly. Have you started on the wiring loom yet?

Minster, I'll try and keep this short. I won't be shortening the cables. If you route them correctly you can get them to curve around in a larger arc. As for selecting the wrong gear it is actually alot harder than you'd think. As long as the cables are the same length then the system should work in unison. And at the end of the day, its a suck it and see proposition like this whole project has been. I take confidence from the fact that Brad's system was unaltered except for the same arm that I had to change except his was quite a deal less radical. As long as the arm arcs through a similar radius and the distance the cable pushes the arm is correct it should work. I guess I will find out next weekend...
