just looking at an ad str8six have it regarding a t350 it say it is producing 330 hp but i would have thought thats what a standard one was producing? always got the impression the staight 6 produced pretty near the quoted power so would have thought a red rose to be nearer 380hp??
I don't think anyones ever seen more than about 375bhp @flywheel from a factory engine - Sag 4.0S, Tuscan 4.0S, Red Rose or whatever. Mine made 370 on TVR Powers dyno and Dom said that was the second best standard 4.0 he'd ever had on his rollers.
my T350t has a 4 liter engine which generates from 380 to 385 at the flywheel with a 20% loss. I will scan the RR result tonight. I always believed 385 was normal for a 4liter red rose.
