Hi guys, I am new to this
forum and have a problem with my 80 series.
I have recently fitted a turbo to the vehicle after believing it was under powered to tow my van. (van is a Viscount Aerolite which I have heavily modifed the chassis and
suspension - in otherwords, it ain't light anymore!) A recent trip from
Geraldton to
Perth had me sitting at maximum speed of 90km/h. I felt that this was a bit slow, but considering the 80 is my first diesel I figured thats what i get for wanting reliablility and fuel economy. Problem is I also used over 90 litres over a 400km trip!
After this i decided that we would have to bite the bullet and part with $3500 on a Denco turbo. This has improved my power and i can now sit on 100km/h if i want, but overtaking is still risky.
From what I have heard and read through searches of this
forum, it appears that my vehicle is still not producing the power it is supposed to and when compared with my relatives 91 80 series turbo diesel,
mine is very slow!
I had it fitted at Turbotech and they ran it on the Dyno which, not knowing too much about dyno's, I thought it would show up any problems if there were any???
The dyno results were before turbo, max power of 44.1kw @ 3248rpm at rear wheels and after turbo 59.5kw @ 3132rpm.
1. Do these figures sound right?? (considering one thread about a 60 series with a 1hz and denco turbo that gave up to 90kw at the rear wheels)
2. If not, can you suggest anyone in
Perth that has the right experience to help me? (I would go to Westend Diesel or similar, BUT, its a bit far to drive over there for a service!)
3. And one other things is that when towing the van, i can have my foot to the floor changing down gears up
hill, and my mate with his 3L turbo diesel hilux (who's right behind me, trying to pass!) can not see one bit of black smoke, yet it seems to use excess fuel?
Any information or advice would be great.. I work on most cars myself but as for the injection systems, i have no idea.
Further info in case anyone wonders is, has done 270,000km, is fitted with a safari
snorkel (and i checked for a restrictor), 2 1/2 inch mandrel exhaust, running 285 tyres and it doesn't overheat at all.. And on dyno says it is running 8.8psi max boost.
As I said, if it is just how diesels are, and it due to me running 285's then so be it, but it just doesn't seem right?
