Re:Re:Lacking power

Hi,
We always had intentions of having a backup set of alloys and tyres. These are 80/20 in favour of off-road so we'd like to get a 50/50.

I'm ignorant with tyres and alloys. I'm hoping there's a middle ground where I can get some lighter alloys and tyres. Current ones weigh 4 times the factory. Do you have any recommendations? I just don't want it to look like I'm driving on smarties.

Back to the origin of this post though... As someone with presumably extensive knowledge on these vehicles; if money, time & effort was not a hindrance, would you get forced induction on this?

I think my point has been lost in the side tracking. My issue is overtaking at speeds over 55mph. Now in most cases this wasn't an issue but yesterday for example on the M6 there was a quick lane closure with no warning which meant I had to merge into my right lane. I indicated and moved but the car in the lane I was moving into was forced to break and I was unable to accelerate to keep the flow of traffic. It's only in circumstances like that & inclines at speed which cause an issue. The gears you'd use for off roading are absolutely fine and it is great but 4th and 5th feel underpowered.

Thanks for your replies

With you and your wife onboard you are 28kg over the legal limit for this vehicle.

Your insurance is invalid.

I note that you are getting upset at the comments that have been directed at you but we on this forum take pride in the advice that we offer. This motor was built as a "Lets throw everything at it" as a sort of exhibition motor and advert. Unfortunately the Jimny is such a light motor that it didn't take long before the weight was approaching critical levels and two things became obvious, mpg went up and performance came down.

You cannot alter this with the spec. that you have. I suggest you look at what was added, decide on what you want the motor to do for you, and then, if you are unsure, ask what you can do without.

TS2211,

You are correct, people are going off at a tangent and not sticking to the question.

All - please keep answers constructive and on-point.

The issue is general acceleration.  

We have no evidence of the weight, we have supposition on top of supposition. 

No. I'm not getting upset I just don't see why people are going so far off track with the question. I have not said here: I'm going to keep everything that's on it and continue to add. Have I? No, people are assuming that I am. I've came here for advice and I've took advice: change wheel setup, consider regearing, remove the winch, remove the snorkel, etc.

Through the night there's been self contained conversations going off this thread that make no sense and are irrelevant. Like debates about whether or not all this was necessary, despite me not doing the modifications in the first place. Debates on whether I've notified my insurance about the changes, (I have) and so on. It's causing the new people who join this thread to continue in conversations completely irrelevant to the principal, like debates on weight additions to vehicles in other countries.

I respect what you're saying about the weight but I've also added 50kg or so as an unknown because the weight of the ARB recovery bumpers, points and underside protection are debatable. Some say as little as 70lbs and others claim 200lbs+.

I appreciate what you're saying but the legality of driving it and the consequences are my own. Being notified is fantastic but swapping the focus of this thread to something we don't know is factual is unnecessary.

Hi,

Thanks for bringing this up. It's true and we are aware of the weight and it's being weighed tomorrow. And we always had intentions of changing the alloys and tyres as we've known they're a bit to much for the average person. But nobody asked haha.

The general consensus is going in the direction of changing the alloys and tyres, if not, regear it. We'll see if there's anybody who's yet to talk about forced induction. It's been spoken about previously on this forum so I imagine it must be an option.

Thanks for your reply.

The problem with forced induction is that the amount of serious development work done on this is relatively minimal. Consequently it is entirely possible to put a rod through the block with too much boost. I would be cautious. Hence suggesting individual throttle bodies as a safer option for a bit more power. The options for a lighter tyre will revolve around the load rating of a particular size, your average bfg will probably be a 106 index or higher and therefore have massive sidewall structure which makes it heavy. Going for a lower rating like say a 96 or 98 index will reduce the weight. It's also worth looking at steel wheel options as off road alloys tend to be quite chunky and therefore not as light as a forged racing wheel.
