Rover V8 Twin Turbo spark plugs??

[neal1980]

Hi,

Im nearing the end of my Twin Turbo Rover V8 Install and need some spark plugs.

I know a few of you have Rover V8 Turbos before :-)

As its turbo now Im guessing I need some colder plugs??

What plugs do you recommend I use??

regards

Some RV8's use very cold plugs anyway. Just use a decent NGK 6 or 7 heat range and it will be fine.

I used to use projected nose NGK 7's. BP7 something or other iirc.

Hi Neal,

Is this install in your Chimaera? Since I have one too , i'd be very interested in info on how your install has gone.

Cracking effort mate. Can we all come to your funeral if the wife finds out?

What a way to go. Beaten to death with a (clean) inlet plenum.

Grade 7 NGKs are the norm for a standard NA TVR with 'normal' CR.
I guess it depends on how much boost you intend to run but i would try grade 8's.
I fitted grade 8's to mine to run 150 bhp of nitrous and found the car ran fine on these plugs the rest of the time off gas.
I am going to try grade 9's for heavy gas use in future

I thought the grade was the other way around but have no clue on sparkplugs hence the question..

So the higher the number the colder the range??

You got a part number for the 8's or do you just replace the 7 for an eight??

NGKs, the higher the number the colder. It can be the other way round on other plugs such as chumpionsn etc.
Use the same spec just change the number.
IIRC BP8ES ??? need to check

BR8ECS

It's a colder resistive version of the TVR recommended plug, including with the stronger ground electrode that is better able to withstand any ping or det.

If non-resitive is preferred, lose the R
