Ive a b230 and i am running LH2.4 inlet on it, i need to know the max power these inlets can make before i go and get my engine tuned. If its going to restrict the engine, maybe i can look at a big downdraft or splits for it.
Engine is b230, 46/38 valves, 298 cam, 11.5 lift, ported 530, and cast exhaust manifold ported too.
I am sure in sweden there is a rally series for a fairly standard set up, but i have no idea how to get in contact with anyone, or any web sites.
But for the moment the standard lh 2.4 i head can only do 170 bhp, but then i saw this vid
I did a few of these many years ago and from my hazy recollection the 531 has a 40-45 [email protected]" flow advantage at 14mm over the 530 head for stock heads. FWIW ported like for like the 530 still couldn't exceed the 531 numbers.
The mani should be a simple job to bring out to a more acceptable csa, but it is reasonably crap as standard.
