N/A Horsepower reality check
because some ppl prefer the ease of a non-FI motor .. i owned a completely built Z32TT pushing over 500hp .. as much as i loved driving that car i enjoy the simplicity of my NA Z33 .. everybody has different prefernces
having gone the boosted route already i will have to say that in the future i will probably build a high compression NA motor when i have to replace this one

As a former driver of a boosted car (400+whp).....I am loving the NA Z.
There are a bunch of built NA z's over 300whp. A couple of HR's, but I haven't seen any stock cam rev-up or non-rev's get to 300whp (though it isn't stopping me from trying 
)

Generally, power modes on Z's NA motor is an exercise in futility for most people. And when I say most, I mean people that will not do things that significantly change VE of the engine that would yield results worth writing home about. Let's do quick and conservative math:
catback exhaust: $1000
plenum spacer: $250
headers: $1000
tune: $1000
For over $3K, you may get extra 30hp, maybe. LOL. That's $100 per pony which is expensive in my book. And I am not even going to start with the fact that once you go faster, you need to stop faster (brakes) and be able to hold that power down at the pavement (suspension). More money. Why bother?
I think on a Z, you're better off just putting that money into suspension and brakes which, in essence, are free power. IMHO, money well spent with very rewarding results.
All I just said does not stop people from throwing lots of money at power mods for bragging rights. Whether that's smart or not is at least a 5 beer conversation.

I dunno, it might matter the difference in Dyno set ups IMO, but the thing with that is everyone will swear that their dyno is the most accurate because bla bla bla.
Example: I did my all my intake/exhaust bolt ons and had it dynoed at Obsession motorsports in Rockville, MD at like 289whp(on a superflow), which had me thinking I might be able to realistically hit 300whp. that was before my tune.
Then I took it to Dave at Funtioned tuned and dynoed before the reflash and it only hit 240ish whp. in the end he configured it in the 260 whp range.(not that Im saying anyone is full of ****)
This is why dynos are iffy to me because they have too many different variables that can make them inconsistant....IMO.
Its all about how it feels after the upgrade, if it was worth it?, finding the right path to make consistant power that makes you happy.
Even though I have a DE, I try to make it faster not to race, but because this car is ****ing fun to drive!!!!

Dave's dyno crushes dreams and shrivels nut sacks.......I only dyno low-mid 260's there (without an corrections).
+1 on using the same dyno. I always get tuned on Dave's load bearing dynodynamics and then when I get time I use the same dynojet (MSP) for comparative sakes.
This is true, but I still think why dyno then if one is not gonna be consistant to another, even after people give their logic on "why THEIRS is the right one".
unless your FI, ....all the rest seems like nickel and dime $hit for bolt on's. If it feels stronger then thats what matters.
But I will agree that "A" dyno is a necessary tool for reflashing and ecu work because it gives you a measurable base for adjusting the tune.
thats just my opinion though.

The power mods can be proven on a dyno. I don't suppose everyone that slaps on #piston big brakes and #adjustable coilovers, actually take quantitative measures to see if their cars actually got faster either. It's a pretty generalized statement to make when theres people wasting their money on brake and suspension bolt ons as well.

Japtrix has always had a mustang dyno, they just bought a brand new one a month ago.
I blew my motor at Homestead and chose to rebuild it naturally aspirated. I spent more than I would of spent on a built twin turbo setup but I wanted to keep the NA engine for road racing. I am going to be lucky to squeeze out 330-340whp out of this new setup, but could of had over 500whp for what I spent. Its all about what you set your goals first and letting the mods follow.

Im not sure what headers yet....and no i have never run the car at the track its on my to do list ahah...but you broke 280 what addition mods do you have that i dont.lol...im trying to get hopefully 5-8 more HP to the wheels...doesnt sound like alot but it would make me happy hahaha
