The V8 Owners Forum -

Jeff, thanks for the reply. Yes the more CCs the lower advance max power is attained. So the max advance of 38 in my map is equivalent to 28 with dizzy-up. Ok that makes me a lot happier now knowing that.

I've been using this ignition map for a while now. It was tweaked by the tuner when my car was rolling road tuned. However since then I have been reading that maximum advance of my RV8 4.6 should be between 28-30degrees however I do not know if this statement was inclusive of the 10 degrees static a...

I've been scouring the net for AFR targets for my 4.6 RV8. Found a few but this is the best I've seen. Comments? http://westfieldbuild.com/resources/v8dev_afr.png the only adjustment I've made is at 45kpa-50kpa/ 500-800 richer to 13.5AFR as the RV8 likes to be rich at idle. My closed loop is only en...

Good point, might be. I'll replace it to eliminate the possibility. Thanks.

I've used the vertical sensor for my ECU and this shows consistent temperature readings. The two vertical holes for are actually not drilled out in mine and I have no need for the thermo switch thingy. The horizontal hole just under this boss is where I have installed my dash switch and this does no...

On from my other thread. I have installed the JE straight out thermostat cover. I am going to install a 74celiius thermostat. I normally drill a 3mm hole in the flange at the top to allow bleed through so stop air gaps keeping the thermostat closed. Problem is the JE casted cover would cover up this...

I have the EFI inlet manifold as used on 3.9EFI. On the front top left there's the standard rover water sensor which I used for the ECU. On the front right there's another temperature sensor installed in a converter, not sure what was there before. It seems that the temperature is not as stable here...

Good points well made. To be honest I haven't a clue what the radiator or fan specs are other than its a high efficiency ali radiator provided by Westfield for Rover V8 installation. Likewise for the fan although I know it makes a racket or you can real feel the air moving and it is protecgted by a ...

Yeah mine was well behaved on the dyno it was on for three hours. but it did have a fan simulating 70mph. Might be more to do with idling, what you got your static advance set to? Well I run without a stat, just the outside bit, due to having a 4.6 front cover, but not the remote housing or heater m...

Jason, Thanks for the positive comments. Also I took five years to build and finance mine including downgrading my daily drive for 2 years to pay for it all. Water temperature at 100 I would try and touch the hoses to be honest especially as I have an infra-red temperature probe anyway. I connected ...

Went for another run today. This time I took some ECU logging. The ECU temperature sensor requires no calibration unlike the digital dash. Started logging at 103seconds after engine start and the coolant temperature was 37celius at 170seconds temperature had reached 45celius which is when I pulled o...

Okay I have installed the JE straight out thermostat cover but before I did I looked it at closely. Obviously the straight out hose is the obvious difference. The other difference is that is not like the standard item which is kind of bowl shaped, this one is cylinderical, the I.D of the bore is alm...

Yeah that's the kind of change I am after. I'll report back this weekend. Take your thermostat and cut the arms that hold the spring mechanism off the body. Toss the spring bit and refit the body. The restriction caused by the body will be the same as an open 'stat. Did it on my Mini and my Alfa. Ro...

Which leads me to a question I have. When my coolant temperature is 87c and using my infra-red probe on the temperature sender I observe the heads are 110c. not sure what to expect? I wondered whether the flow would be too quick for the water to conduct the heat quickly enough- meaning the radiator ...

I see. I also been informed that it would take too long to come up to temperature if at all. I'll leave it in. At least I can observe what effects changing the cover to lower the top hose will have. I've been wondering how much the standard RV8 thermostat impedes water flow by, when open of course. ...
