guess my horsepower and win nothing

2005 Corvette C6 Z-51 6-Speed 30,000 miles
What I have done to the car
Vararam and Throttle body spacer – $390 for both shipped
Ported intake manifold - $225
Port and Polished throttle body – Free I did it myself
Removed cats $50 for replacements so I could get the flange, sold cats for $70
Straight pipe $10
Removed MAF screen – Free

Heat shielding around upper radiator hose – Free
Royal Purple in transmission $30
Drained 1 gal of coolant and replaced it with 1 gal of distilled water and 2 bottles of redline water wetter to help the thermal efficiency. The car still has the stock thermostat. Cruising the car runs 192-194 degrees
Amsoil oil and filter
Catch can $20 each. one on PCV and one on FAT

Magnetic drain plug $10
Optima yellow top
Oil cooler 11” x 5 ¾” x 1 ½ “ 130-70264 from JEGS $63
(still using stock oil cooler as well) Fittings and lines $10

Yes it still has the stock exhaust manifolds and stock exhaust.

Have spent about $700 in performance plus $530 for the tune and dyno time.

what kind of horsepower do you think i will put down to the rear wheels
to make things easier on a dynojet with 12.8-12.9 A/F

 

Not enough. Horsepower is like garage space, you never have enough.

The Optima Yellow Top is good for 10-12 HP alone.........

 

365 or 385 or 405 .....

 

370?

 

OHHH it's a LS2... 199.... If it was a LS3 515

But really 375?

 

I will guess 372. When will we see the graph with the info???

 

366 rwhp

 

Spark plugs Denso Iridium IT20 1 step colder indexed - $50 You need to look at there web site the lower there # on plug the hotter the plug. Hope this helps. Bill B

 

If you installed Pulstar plugs add 29RWHP

 

371 rwhp.

 

BWAHAHAHAHAAH!!

 

I'm going with 370.

350 Stock, 10 for a tune and 10 for the mods.

 

345 stock, 10 for the mods (mainly the ported intake & tune): 355 total.

 

ok here it is

351 hp bone stock – dyno jet
367 untuned 13.5 A/F on RX7 stores brand new in ground dynojet.
377 hp 357 tq tuned 12.9 A/F 23.5 degrees of timing on RX7 store dynojet by Rob LaSota
After data logging it at Mid-Ohio I detected some knock so I took it back and without changing the tune it put down 398 RWHP uncorrected.
SAE corrected it made 390
Made 4 pulls 2 were 389 hp and 2 were 390 hp. Done pretty much back to back.

87.87 degrees outside temp
29.25 in-Hg
24% humidity
1.02 SAE
Full smoothing
Only thing that was different was I changed my Fresh Air Tube from having a breather to putting it back to stock (connected to the intake) but with a catch can. I also added an oil cooler and switched to amsoil.

390 RWHP 365 Ft/lb Torque for $1200 including a tune.

 

That is stout for the minor perf mods you did! Great job!!!!

 

sorry if this sounds extreamly stupid but I thaught the 2005 came with 400 hp stock?

 

400 HP stock to the motor which with a 15% drivetrain loss is 340 HP to the wheels. if you want to go by motor horsepower mine is making 460 HP to the motor

 

Thank you for the info. Guess that's why I was told after my mods that I was producing 460hp and 475 lbs of torque. New to the site and a very new to vette mods but i know that the speed shop made my car VERY fast. Thanks again

 

I guess that I just wasted $1800 for headers, with less horsepower. 390rwhp without headers.

 

I'm going to guess somewhere in the neighborhood of 389-390+ rwhp and 364-365+ lb/ft of torque...am I close?
