Pappu now that you've got all that shit out out of your system, go weigh yourself.
Everybody else use the search, this has been covered way back.
Are you all referring to Gen 1 WAIC vs TMIC/FMIC? or aftermarket?
GEN 1 WAIC will never manage anywhere near those numbers without extensive modifications to flow and heat exchanger size.
It might net a decent peak figure on the fucking dyno, but subsequent runs will show a lesser number.
I had a friend who fitted a VF22 to a stock RS (WAIC) and pumped 20+psi through it, we tapped a temp sensor into the WAIC tank, a few pulls and temperatures soared.
The water would eventually boil.
