Can imagine how empty having to run a 4.6 Rangie on petrol

My Landy V8 at best does 15mpg

- Only has 130bhp too

My 4.6 only produces about 240BHP... Does anyone have any knowledge or experience of a company that can uprate this just by re-programming the ECU? Cheers.

Ohh and any increase in mpg would be a lovely Xmas bonus

 

Try Pistonheads the TVR based forum...they'll know all about options for tuning the V8s...

 

Search the pistonheads forum for the number of a geezer called Mark Adams.

TVR power. the ecu on the range rover is set so the rev limit is a lot lower than when in a rover, than when in a tvr. My old 390se had 275 bhp but did run a high lift cam, 10:1 compression ratio, a straight through exhaust, and stainless headers. Oh what fun that was on a damp roundabout!

Chipping won't really give you any massive power gains on the R-V8 IMO. May help the 4.6 run a little cooler as the standard set-up is very emissions orinetated. Doubt you get much MPG improvement...if you want MPG get LPG

It's a combintaion of things that need to be done really. Uprating the cam would be a good step (although there may not be much options for the 4.6 as most cams will have the dizzy and oil pump drive suited to the older 3.5's). A big valve and flowed heads is another good step, with uprated pushrods and rockers. Then you can have the mapping changed to suit the mods you've done.

Potentially you can get big BHP from these engines, but it can't just be done by one or two mods, as many components need to be uprated to keep up.

You could always just drop in a Big-block Chevy engine (aka Overfinch)

 

Thanks for the tips guys – esp the Mark Adams one.

Used to have a TVR V8 S no cats – I can IMAGINE how well that sounded misty.

Ali B – have you seen how empty my wallet is mate 'just drop in' a new engine' indeed :d
