well its been a week and ive been messing about.one of the first things i noticed was that it tended to hunt slightly when cruising,not a big problem but noticeable.phoned bob and he said it was likely to be the box doing this and some cars dont like having them put on.i asked if this was retuneable but he said the 7 notches on the box were the only adjustment.i then set about trying different settings to see if this could be got rid of but it occurs all through the adjustments.here is my opinion/testing that was done.the bus was driven the same route on each test,briefly onto the motorway up hill and then off at the next junction and return to start point.here are my findings:
1, had to try it with the box off just to be sure that hunting wasnt there,test complete all ok back to normal,nice and smooth,no smoke when booting up hill on motorway
2, box fitted and on first notch,bit better all round,bit of smoke on booting
3, 2nd notch,bit better again,smoke about the same
4, 3rd notch,more noticable power around 60mph,tad more smoke
5, 4th notch,little pedal needed for low down power,definate noticeable grunt when hitting/passing 70mph,smoked like a builders van when hoofed
6, 5th notch,as above maybe more driveable,more top end delivery,smoke as above also this is probably where the smoke becomes quite bad
7, 6th notch,this is where i could not believe how much power was delivered at the top end,it comes in strong over 3000rpm and just keeps going but when you ease off the pedal the drop off is a bit savage
8, 7th notch,not really noticeable from the 6th notch
when driven normally no extra smoke is produced,only when you put your clog down and you dont have to now,although when you get to about the 3rd/4th notch the power produced lower down is fantastic and a bit funny to get used to at first because the brain is telling you your right foot should be down more for the speeds your eyes are seeing.
good points are:
more power
bad points are:
cost
the engine hunting(not a big problem)
before any of the work was carried out i used to think i had quite a nippy bus for a 2 ton diesel.now ive had the work done i honestly didnt think it would have made such a difference.it isnt a get away from the lights machine(although she does go a bit) but where you do notice it is on the hills,before i would hope it was still gonna be going the same speed when i got to the top,now i can accelerate up em no hassle.
in my humble opinion if you are keeping your hiace and have niggling doubts that you could do with a bit more power then the
DIESELBOB BOBBOX is just for you.this power module also fits the 3.0 turbo diesels i believe(god only knows what one of those would go like).all things considered intercooling would have brought safer gains but the cost/access outway the cost/access/more power that the bobbox offers.who knows maybe theres a future cooling project for somebody there.any more info or help just ask or p.m me
.
ALL VIEWS HERE ARE SRICTLY MY OWN AND PEOPLE WANTING TO FIT THIS TYPE OF MOD DO SO AT THEIR OWN RISK.ALSO ANYONE WHO CRINGES WHEN AN ENGINE SMOKES THEN THIS MOD IS NOT FOR YOU,THIS IS HOW IT WORKS, MORE POWER = MORE FUEL = MORE SMOKE GEI IT
