After more power 4.2 carby dual fuel

[taslucas]

How many kilowats does an LS1 have? I was just reading about a GU in a recent 4wd magazine. It has the 4.8 petrol with stock internals but with a turbo strapped on. He is getting 260 kilowats at the wheels on 35" tyres. Pretty nice!!

Yeah I get your Idea, I was thinking similar that's why I like the Idea of turbo myself, have a look at Marks Adapters web site.
he has a page that lists most oem engines, kW, HP, NM @ rev's .

The one I was talking about was a 4.8 not a 4.2 so I suppose you'd get a bit more there. But it shows some pretty big power gains. So it had the 260 Kw @ 4200 rpm and 1230 Nm @ around 2600 rpm. And yeah these figures were 'at the wheels' on 35's. Impressive!

As whats been said its hard to get both LPG and petrol to both run well
Not many bother spending the bucks on a carb 4.2 as for the money to bother you can pick up an injected 5L V8 for about 1500 bucks, if even that nowadays
To spend even more on the TB , the 5L will have you all across the board
Then nowadays the LS1 engines can be had cheap
Im maybe not sure how much more power your chasin ???
How much money you spending
If for some reason my 4.2 pettie stuffs up , i wouldnt be spending any money on it , it would be to a V8
Itll have the same economy ,or lack of and heaps more go
After more power TB42 dual fuel ???
Maybe my answer should have been
How much money do you wanna spent
Up near 4 grand, go V8

Hi Bro.
$4K Me don't think so, more like $12k for a half decant job and not a bunch of unreliable 2nd hand parts.

Yea sounds nice.
Thats the sort of reason I cant understand why bother e/swapping.
A 4.2 with say 30% turbo power up why bother go else where.
just efi by itself only a couple of kW and Nm but add a turbo, presto.

now fellers don't worry about written to argue about the merits of e/swap, it's simply a matter of personal choice ok.

Is that figure nm correct, sounds alot

Probably close to the mark - I'm not looking for a fire breathing dragon, but figures of 200kw+ and 800nm from the 4.2 was what I was told is more than achievable ...

That said, I'll be sacrificing both if needs be when it gets dyno'd for outright drivability and engine life ... if I get around 160-180kw at the rears (compared to about 90kw off the showroom floor) I'll be stoked.

Im fairly sure thats what it was. The mag is at work, i'll have a look to confirm when i go back monday.

A mates GQ TD4.2 Ute has a bigger turbo put on and bugga all else and he had it at 1080 Nm on the dyno. (i know diesel has more torque to start with)

12g will give you more than a half decent job mate.

Ok, having a look at the mag right now..... I was wrong about the torque....it's not 1230 Nm, it's 1250 Nm!!! @ 2700 rpm. And 260kw @ 4200 rpm. that's bl--dy tough! Maybe the owner is out there somewhere? Would be great to have a chat if you are.
