“Merlin F85” heads for the Rover V8 from Real Steel

[Else]

Anybody tried them? how much better are they than stock modified ones? BHP or Flow figures?

Any info or advice would be appreciated

I guess nobody here has tried them then.

Andy give me a shout on monday if you are looking for some stonking rover heads, i have a set that you may like?

Hi Rob,

I'll call you later today then.

Nearly there, just got to make up an air filter box and the pipe work.

Matt,

The runners are approx 7" from the back of the valve to the lip of the bellmouth.







You can just see the link tube, -10, at the back of the plenums in this picture.



Jonathan,

Rob at V8D sold me the heads, he explained at the time how the intake should be designed which i have stuck to it as near as i could.

Finished the air filter housing pipework install today. Very pleased with it

Just got to tweak the mapping. There's a guy local to me that knows a lot about mapping Motec ECUs apparently so I am going to contact him to see what he can do for mine. Then get the geo set up professionally and I'm done.



By the way, I can't believe nobody wants my old inlet manifold and twin plenum setup, it was the nuts. Have to sell it cos it won't fit my new heads

Need a bit of advice: I now have an oil catch tank instead of venting the crankcase into the inlet but the little foam filter at the back of the nearside rocker cover is pushing out a little bit of oil. I can pipe this into the catch tank as well but will this cause any problems?
I realise that I probably have positive crankcase pressure now instead of negative as before but will this cause any damage to seals or gaskets?

Thanks Andy

[Else]

Ian, it's a 5.2 built by V8D and it's running a self installed Motec ECU

Make me a sensible offer Dave, I can always say no.

Sorry cant help, didn't go the Merlin route in the end, my heads are modified Rover heads from V8D.

Any update?

Are those heads V8D/Vizard heads? Look like they have been welded seriously..

Hi Timo, yes and yes.

Was thinking about a set of F85 heads but in the end went with the V8D stage IV heads.

Nice mate, what size are the valves?

Andy

griffdude said:

Compared to your Wildcat heads, yes no contest. Not even in the same league I'm afraid, but to be fair, the V8D heads weren't in the same price bracket either.

By my crude measurement mine are 50mm and 42mm.

Apologies all, feels like this is turning into a "mines bigger than yours" contest!

How cute, only 50mm. My intake is 51mm. I'm embarrassed to say my exhaust valves are only 41mm.

Somehow managed to crack three liners so the engine is out again so I thought I'd take a few pics and post them here.

Hi All
Been a veiwer and a Chim owner for many years but never posted. So here goes. If Else still looks at this post can you tell me where you got the alloy pipe made up for the twin plenum set-up? Its just what I've been after for my set-up on the Chim. Or failing that if anybody knows of a good fabricator to copy whats in the pic on this post, please let me know.

Welcome Mate. The guys at ProAlloy did it, top blokes Google it, theyre based in Haverhill Suffolk.

Thanks for the info, Andy - Will contact them later in the week.
Did you manage to sell your Twin Throttle setup?

Pete

No mate, I'll try again in the spring.

They are Vizard heads which were for sale on Ebay this summer ?

Not these mate, I've owned them for about 4 years.

Andy

Literally just found a guy this week to map my Motec but waiting for some dry weather! Once its done I'll probably take it to SRR to see what it produces. Looking for a long flat torque curve rather than out and out BHP.

Andy

[Else]

I have a M4 which is a bit overstretched on a V8 using up all the spare outputs but I am going to persevere with it for now.

There is a guy in haverhill, suffolk that is experianced on motec mapping particularly turbo/supercharged installations for drag racing, cars and bikes.
