None taken, lol.
It's hard to say without flow bench data I suppose but it certainly appeared to work in my case.
Don't forget of course that the stock manifold was designed with a completely different brief, they weren't concerned with revving to nearly 9000rpm or producing nearly 700bhp.

Did a bit more with the car yesterday after swapping race fuels.
The C85 is great but using approx 35% more of it meant I couldn't run the nitrous.
I've now swapped to Sunoco MAXNOS fuel mixed with 20% methanol. This gave me the headroom reqd to run the nitrous so in went a 40 shot and this is the result.

Got the car to a local drag event ran by Straightliners today.
Ran a new PB of 10.06 @ 165mph although the terminal is a little questionable.
Ecu logged 157mph so I think that's probably closer.
9s are beckoning

Shy of an MOT but yes essentially it's road legal

I think the point has already been made but if this weird effort (no offence!) can work so well how inefficient must the OE manifold be? Has anyone actually built a totally redesigned manifold starting with a clean sheet? It looks like a key area for serious power gains.

Congratulations, I bet your manifold experiment has got a lot of people thinking!

Just been checking out this subject on NASIOC, they go into it quite deeply and some of the pictured manifolds earlier get the thumbs down, mostly for poor fit but some for unsatisfactory results. Interestingly it opens up the possibility of twin turbos and all that might entail!
