Real Steel Merlin Heads

[Chassis 33]

Has any one tried these new heads yet? What are they like? All I've seen onpaper is that the inlet valves are larger than a stage 4 head at the expense of the exhaust valves. How do they flow compared to a worked set of OEM heads, cos at £1100 for a built up pair they look good value?

The web site ad says ..."exhaust ports raised slightly" almost like an afterthought. I thought that was the big story like the Wildcat heads

I believe they're raised by 1/4" which might cause some folks trouble. I think it's to try and improve flow. If you look at say a set of Stage 4 heads a lot of folks open out the roof of the port tract as much as possible...maybe that's what's gone on here from the start?

Don't think it would even come to that on the Chimaera, headers and y piece all move up as one and the main exhaust has a new hole drilled in the bracket that mounts it to the block (for those who use it, I don't on the racer) job done. The big question is how do they flow compared to others. looking on other forum it appears that the heads are designed to give better manners at the bottom end (something Stage4 heads are apparently bad at) but still keep up the flow rate for the top end, but I'm yet to see back to back comparisons on a flow rig. I'm going to email Real Steel and see what they say.

BUMP!!!

Has anyone had any more feed back on these heads?
