1nzfe equal length manifold.

Why do you think that race cars that have had millions of dollars of engineering behind them build manifolds with long runners? Nearly every drag car you see has huge long runners.

Your manifold design isn't a bad one. Its functional and thats what matters.

If i were made of money i would buy your manifold.. put it on my car.. dyno it.. then put on a manifold with longer runners and dyno it. Thats the only realy world test we can do. going back and forth on an internet forum is useless.
