The V8 Owners Forum -

there is a very good chance that the throttle response was not a function of the MAF but of the way the engine was mapped. Generally the OEM calibration on the ECU is done to minimise the chance of idiots spinning into the scenery on the first wet roundabout so maximise linear operating range. The ...

1 - why? Cos i have way to much free time, i like a challenge, and i did it to my Supra and the throttle response is soo much better..never been a fan of maf! 2 - I've never heard of anybody doing that mod with the existing ECU. In fact, the stock ECU is notoriously difficult to do anything with. T...

Hello, i fancy changing my 1996 R/R 4.6 V8 from maf to map, i want to get rid of the air flow meter permantly! is it possible to do this without changing the whole engine management system? I have done this to my Supra, fitted a piggy back unit (HKS vpc) that by using map and ait sensors feeding sig...

hi all, i have recently fitted a K+N induction kit and de-catted my 4.6 r/rover. it also has no rear box so just the centre one now, any ideas of what the power increase from this will be?

been doing a bit more to it!



and as well as having no rear silencer its just been de-catted. sponds great, i love V8's always have.

I've found with all the rover V8 engined vehicles I've ever converted (and I've done a few!) that there are no issues at all if you use genuine leads, NGK BPR6ES plugs gapped to 0.030" Interestingly enough, my Disco II 4.0 which I have just sold was running NGK Irridium plugs - no issues or wear af...

i have lpg on my 96 4.6 hse V8 r/rover. its brilliant BUT you do need to keep the ignition in tip top and close the spark plug gaps. mine are the standars NGK plugs but gapped to .7mm. i have magnecor leads that made a massive difference when fitted recently. lpg will eat spark plugs so be ready to ...

1996 r/rover 4.6 V8 lpg on Koni "heavy track" adjustable shocks, soon to be fitted with nitrous! full engine rebuild 8-9k miles ago with top hat liners. http://i211.photobucket.com/albums/bb254/broad55/Burnham-on-sea06057noreg.jpg http://i211.photobucket.com/albums/bb254/broad55/april008.jpg and it ...

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...

excellent news, i know about cooler plugs as i run them on my supra already, bcrp7es instead of 6's, ignition may be difficult to change as it aint got no dizzy! its the coils pack thingy. i run normally on lpg and therefor my plug gaps are smaller than normal, 0.7mm instead of the 1.0-1.1mm for pet...

so im guessing that 100 shot to take me to 325hp would be ok with the big and main bearings!! its not going to be used big time, just a little more grunt away from a standing start and it prob wont be often either, its something i always wanted to do! the block is cross bolted, i been asked to check...

im an old owner of a V8, its been sitting in my range rover for the near on 3 years i owned it, its been recently rebuilt with fresh block and top hat liners 8-9k miles ago and has been kept tip top. im new as in just decided i want to modify it. the question is how much power can i safely push with...
