Dyno after all bolt-ons.

Dyno after all bolt-ons.
From what I've been reading the M6 f-bods tend to put down just a tad over 300rwhp stock.
If you had all the power adding bolt-ons ( I will have ud pulley, headers, ory, catback, and tune) then what would be a reasonable number to expect to see.
I have a dynoday setup next month and I will get a base dyno with just lid, catback, and maybe a tune. What should I expect? 305rwhp?
I know I remember seeing a thread about this already but its hiding at the moment.

Nothing like bolting on some 40hp in less than a day.

This all depends what type of dyno it is, what correction factors are being used (SAE, STD) and what level graph smoothing.
Non load bearing dyno's such as most Dynojets read comparitivly high when comparing to SAE Net numbers such as quoted by manufacturers. Load bearing dyno's like Mustang Dyno's offer a more realistic value as a comparison.
350rwhp SAE on a Mustang Dyno is a pretty sensible number for a bolt on car. This would be about 370rwhp on a Dynojet.
Remember there is only so much power to be freed up with induction/exhaust mods before the internals of the engine become the most restricting parts.
All advertised gains for mods are compared to a STOCK car so if you already have mods then they generally will yield lesser results, this is due to diminishing returns.
Example:
Typical claims for gains against stock
Headers/ORY = 20rwhp
Catback = 5rwhp
Ported TB = 8rwhp
Lid = 10rwhp
LS6 intake = 15rwhp
Pulley = 10rwhp
K&N filter/smooth bellows = 2rwhp
This totals 70rwhp increase over stock, but a car that made 300rwhp stock is most likely on a Mustang dyno which would make this number far too high over by about 20rwhp or so.
Anyhow dyno numbers don't mean a great deal as a dyno is a tuning tool not a measure.

When I had headers, catback, lid, 3.73 gears and a 3200 stall torque converter I dynoed 335 rwhp on a mustange dyno.
You allways get a little more drive loss with a automatic.
It was running 12.8 at 108 mph in the quarter.
Good luck,
Al

I got my car dynoed yesterday with : Lid, LS6 Intake, ud pulley, LT's, Corsa Catback, ported stock throttle body & 4.10 gear I put down 347rwhp.
Before the 4.10's I put down 355rwhp
