Given that we don't know what "etc" consists of? 1.6 rollers and EWP, and if you haven't done the TB Bypass, that's a possible total of 20hp. I'd think you should be close to that, or there, with what you have already though.

Dyno numbers vary depending on the dyno you use. MPH is a better true test of horsepower...take it to the track!

TB Bypass worth that much huh. To be honest I dont know if that's done or not but if it isn't when the car gets here (in the process of getting it shipped from my buddies in SC) it will be done so lets assume it is.

-Moroso CAI & TF Elbow (may swap for LS1 lid)
-AS&M Headers (need installed
-ORY, no cats
-Borla Cat back (old style, no plates)
-PCMforless tune (will be a mad tune when headers get installed, then tweaked by me for elevation)
-LT4 Knock Module
-Under drive Pullies
-Dynaspark Opti
-Taylor OTVC wires
-!AIR !EGR !EVAP
-Possibly ditch all the A/C components since the pump is bad anyway.

Future
-EWP as you said
-1.6 RR's as you said
-Valve Springs (needed with the RR's?)
-MAF ends on the stock maf? or leave it alone?
-ported tb? Dont want to go 52mm til I make more power
What else can I do that is a "bolt on"?

Car will eventually have an AI custom cam. and then a set of 200cc heads even further down the road.

Thanks

Believe me, it will be at the track lol. I know dyno numbers vary. I would use the dynojet inertia dyno close to me, or the superflow. Both have been known to be very accurate and give numbers w/in 3-4 hp of each other.

I know MPH is the biggest indicator though, so what is a 300rwhp, m6 mph?

Bypass is worth a handful, the 20 was all of them combined. Could be more, could be less. Do the springs, no point in keeping the stockers, and then you can get a cam later w/o having to do them. Ported TB will BECOME 52mm, so either you want a 52mm or you don't Leave the MAF alone. That pretty much rounds out the "Bolt Ons" list from what I can tell, but I'm sure I'm missing something. Well, injectors but you don't need them yet. Unless you have over 100K on the stockers, then they could HELP (like throttle response), but they only support HP they won't MAKE it for you.

And we've actually had people make, or make damn NEAR 300hp on a stock LT1 through an M6. They're the damn lucky factory freaks heh

factory freak I'll say!

I wonder what the car would have put down bone stock. It did an 8.801 in the 1/8th with only a repl panel air filter. bone stock. I thinks that's pretty good time through and M6, it definitely had the driver mod. My buddy can whoop one down the track.

So should I port/52 the TB at this level or not? Thanks!

wow, maybe I'm overthinking the 300 mark lol.

I am at high elevation though, so it's gonna take more to get the MPH there, although the dyno numbers would be "corrected" for good air...

Best I ran with it was 13.5@104. Yeah I can't 60'.

Mods were BBK shorties, Flowmaster catback piping but I had a bullet welded in and got rid of the big *** square non flowing bastard muffler, no cat, 1.6rr, CAI, msd 6a, TB bypass, trick flow ceramic elbow, stock tune. Doesn't take much.

that calculator was way off for me. the only way to know is to dyno it or to take her to the strip.

my car ran 13.32 @103 with 280/317 with a catback only. Im thinking LTs and ory would have put me to 300. Built the entire car since so I will never know.

an ewp and tb bypass, would possibly free up hp? is it really worth the price of the ewp tho?
