The V8 Owners Forum -

Hi,

I have a standard carb 3.5 I want to get a little more power out of without spending too much or rebuilding the whole engine.

maybe put new perfomance manifold with carb 500cfm being good?
So.... I will be running LPG. What kinda things can I do to it?

maybe cam from 3.9 is it good idea?

welcome to the forum mate,
Im not that clued up on LPG, so hopefully one of our more experienced members with LPG will reply to you shortly.

hi, im a lpg user in a 4.6 r/rover V8, from what i hear it reacts very well with forced induction and you can use NOS with lpg as well.
im currently trying to find reason NOT to fit NOS to mine and i cant find any!
trouble with n/a engines is the amount of work and money it cost to up the power even a little, a nos kit is quick and very effective!
you can bet ya ass someone else will know more or different to me, lol............

See my reply in your other DOUBLE post!!!!! Please try and keep the same questions into one thread otherwise you will get answers all over the place.

Welcome by the way

could use a coulpe of remote mount turbos?

You will see a big drop in performance between LPG & Petrol. Running on LPG costs me 40BHP.

So just to regain the performance of petrol would need some serious effort.

I believe this effect to be mainly due to the lower calorific value of LPG, so to compensate, you need to get more in somehow. So normal tricks are needed, e.g. cam, heads etc. The LPG mixer is normally a pretty serious restriction, so fitting LPG injection is a good idea for starters.

i think you pretty much hit the nail on the head there
