G'day.
I'm gonna risk the can of worm's.
I've been reading the post by FlyinOBrian2

Why do Formula 1 racers using O-200's use straight out stubs if it robs them of grunt ?
I have an RV4, ( an since I've owned it l don't need Viagra any more, an I'm 70)
l have considered replacing all the exhaust spaghetti with short stack slash cut 45? backward facing pipes.
Why?
Lighter weight, a bloody lot less heat in engine room, slightly aft shift of C of G,
(an that should give a coupla knots extra speed)
l don't give a dead dingo's donga
Fer all that exhaust technology, I'm not interested in every fraction of extra speed.
I'd rather have less heat, less spaghetti, more room in the engine room, an better air flow around the sump.
Nobody involved in those posts mentioned less exhaust valve temperature with
shorty' s
I'm real keen on knowin ( without Goin into too much detail) what I'm gunna loose OR gain running an io-320 at 2400 rpm.
Thank's.
An by the way,,,, I reckon Don's doin a good job, he'll get in again fer sure an when he's finished there send him over to us, we can give him a job, an pay him too.
