Love it Phil!

 

I think you may want to consider a day box swap rather than a dog box, it's very much an option as it's been done a few times now! (Effectively a cheap sequentially box in my eyes!)

Hey buddy.  Great to hear from you. I take it you wrote Dsg but auto correct changed it. I absolutely agree with what you are saying and watch this space to where the rattler goes after I reach my 10. 99.  The trouble is I have a goal with this car and I can’t change it until I get there. The goal was set along time ago when my ego was trying to prove its own worth. The goal was a 10 second naturally aspirated street car using a Peugeot engine and gearbox. ( I’ve dropped the street car bit now as that means street tyres and very unrealistic with my budget.  However I’m close and I m loving the journey for what it is and not so much the goal if that makes any sense.  I can’t wait to see how fast I can get this pug when I remove all the restrictions and don’t make it difficult for myself.  Behind the scenes I’ve been doing a lot of self work and i really feel like I don’t need to prove my worth through the things I do or achieve anymore.  Thanks for your comment and support Dan

I remember you saying about that goal many years ago! You're certainly close now!

 

Good to hear you're keeping well, but surely it's time to update the 11.40 in your signature

 

Catch up with you soon mate

Just a brief update, i decided to ditch the gearbox ideas for now. The current plan in true Jeremy clarkson fashion “ more powwwwwer”   
im going to be running new fuel in the form of nitro rc car fuel. 25% nitro. I’ve upgraded all my fuel system so it can run alcohol based fuels, fitted a large fuel pump ( Weldon). 900 cc injectors and bought some ngk 7 and 8 spark plugs to see which ones it likes.  Dyno day will be booked soon to see what it makes. 

Any guesses to what power it might produce??  I’m hoping it’s in the 340 to 350 range which should( if the transmission holds it) see me into the 10’s.  I’ve had a new logo made too which I think is pretty cool. I’ll post that below.  I will update after the dyno day.

Just thought, what gearbox ratios etc are you using, what gear do you go over the 1/4 in?

We deliberately geared the mini so it was just about flat out in 4th (out of 4) over the line, obviously shorter gears is better acceleration. 
A shorter final drive maybe, from rally experience there are quite a range out there for BE boxes if that’s what you are still using? Up to 5.0something :1 out of an Expert van is the shortest.

The other thing we had was a really long 1st, otherwise the short final drive makes 1st useless, it will only do say 20mph. However in your case maybe you could then launch in 2nd and use 2-3-4-5 instead.

i believe colin satchell went the other way, to keep the simple 1-2 3-4 gates, longest BE final drive possible, i think a 3.6 or thereabouts, even had a 5th gear lockout.

I can absolutely agree with that from my drag racing days, if you were ever going to miss a cog, then across the gate from 2nd to 3rd would be the one.

Hey Tom, I have a be3 with a mi16 final drive 4.1. I cross the line at top of 4th around 8000 @ around 119mph so still have another 1000 rpm to get me between 125-130.  I think being na the ratios need to be really short. If I was boosted I would definitely use a lower final drive as the terminal speeds would be so much higher.  
im really trying to take what I’ve got and make it work. I looked into dog boxes with great gear selections and final drives and the cost soon added up.  Dsg I think is in the future for sure after I hit the 10. 
This fuel swap is costing around £1500 by the time I’ve had it dynoed and bought the fuel. 
fuel pump was £150 second hand 

fittings, lines, filter and regulator £300

injectors are £330 with the spacers. 
dyno between 400 and 600. 
fuel was £150 for 38 ltrs of m1 and £300 for 40 ltrs of nitro.  
I have a 10 ltr tank and could get 3 runs previously before I started getting fuel starvation on the launch.  So will be interesting with the quantity of fuel it will use on the nitro having an air fuel ratio of around 4/1. 
Thanks for the comments guys.  Can totally relate to going from 2nd to 5th. Done that a fair few times.  I think having the thought of the money shift in your mind, I sometimes overcompensate and reach for the 5th.
