The problem was the heat from the brazing - MIG or TIG should be better
There is also the rivet and glue approach - which I found tempting but chickened out as I was not sure about getting it through our certification process
The problem was the heat from the brazing - MIG or TIG should be betterDo you think TIG welding would also be a bad idea, due to the potential of ripples? Or was that specific to brazing? I really like the idea.
Yes I have done a fair amount of that in the past - it requires much more careful preparation than gas welding but it is doableIm wondering if anyone here has sucessfully welded to car sheet metal with a arc welder? (cheaper than other types of welders) It seems possible if you turn the welder right down and tac weld back and forth with stops to cool?
Not reallyI know you've increased your tire diameter to decrease motor RPMs, is it worth changing diff gearing? Did the increase in tire diameter noticably decrease your low speed power at all? Seems like you have plenty of it?
On the 1/4 mile I got to 104 mph (no traction at the start)Not really
I went from my 195/60/15 to 225/45/17 Nittos to get more grip - THEN I went to 235/45/17 Nexxens to drop the revs a wee bit but mostly so that I could use the Nittos on the front when on the track
195/60/15 --- 518/km - initial -- RPM at 96 mph (153 kph) - 5436 rpm
225/45/17 ---- 502/km - 3% larger RPM at 96 mph (153 kph) - 5248 rpm
235/45/17 ----- 495/km - 4.6% larger RPM at 96 mph (153 kph) - 5175 rpm
I'm having difficulty getting the Nexxens to grip - the slightly smaller Nittos appear to have more grip - so that is the limit - not the available torque
A taller diff might help - If I see one I will grab it - currently a 4.1:1 Subaru limited slip diff
It did 5.967 and 125.4 in the 1/8thDid you note the EVO's time/speed in the eighth?
Ask the firefighter to be your girlfriend, throw her either in the trunk or the passenger seat as race conditions warrant.A couple of autocrosses - video on my Youtube page
Last Sunday we had a triple event - 1/4 mile drags - grass autokhana and tarmac autocross
Tried something new for the drags - 40 kg of sand in the boot
Made a HUGE difference - ended up with an 11.75 !!! - the next fastest guy was 12.54
The grass event was a wee bit bumpy but fun
Then in the Autocross the organizer asked if I would take a passenger - I said yes and took one of the lady firefighters
(took the sand out)
Made a surprising difference - the car felt much better with a passenger - I ended up 4th - I'm normally more like 14th
With that behind me I went to the Good Friday Drags - used the sand again but could not quite get below the 12 seconds - the Autocross club uses a timer that starts when the car breaks the beam - which means that my 0.3 seconds reaction time doe not count
Still had a great time
First run was against a supercharged V8 T bucket - his reaction time was better than mine - we were almost level at the end but he was just in front
Then a nice newish white Falcon - beat him
Then another supercharged V8 T bucket - beat him
My last run was against the BMW M3 that I beat last time - he had got a "chip" and some drag tyres
A great race! - he beat me by about the length of his bonnet!
Last event for this season - My device has been on the road for 9 years so its time for some paint and a bit of a rework
I'm thinking about moving some of the batteries into the boot and trying to lose a bit of weight (the car as well)
I'm 55/45 rear/front at the moment - should I aim for 60/40 ???
Any thoughts?
Sandbag and passenger suggests you're traction limited. Ever go rock hard on the tires and did it get worse or go softer and it got better? In my V8 pinto we ended up with 15 psi in the rear M50-15 but should have used bead locks.[\quote]

Don't think I would get away with that! - I would be in favor but she is (I think) about half my ageAsk the firefighter to be your girlfriend, throw her either in the trunk or the passenger seat as race conditions warrant.
Wife says it is embarrassed response to lack of male endowment. She also says she is sorry for themThat's why most old guys buy Corvettes over here....
Cheapskates use stainless - or possibly aluminiumStainless is heavy - real men use titanium...
I have a mentor who, whatever he suggests, I start thinking about a halfassed step down from it as sufficient.Cheapskates use stainless - or possibly aluminium
