How much horsepower do u guys think my car has at the Wheels? I have not have a chance to race anyone or dyno it or take to the track. ASP Pullies are NOT installed yet. MODS in sig.

 

I would say about 340 hp and about the say tq.

 

Really? Seem kinda low to me being my car is a 2002. I thought these cars are pulling around 315 RWP STOCK??

 

takr it to the track and youll find out

 

Yeah,I know but have not had much time. Just wanted some numbers from people with about the same mods...

 

2002 Pontiac T/A WS.6 M6, Blk/Blk, LS6 Block
BMRSTB -no power gain
SFC -no power gain
PHB -no power gain
LCA -no power gain
Tunnel Brace -no power gain
Relocation Brkets -no power gain
SLP Bilstein Shocks -no power gain
Eibach Sportlines -no power gain
TSP Clear lid - some gain add 7rwhp
SLP Bellow- little to no gain
Holley Air filter -no gain lose 3rwhp
Predator- if mods can be accounted for with the programmer and your A/F is good then some gain
ASP Pullies- some gain add 8rwhp
160 T-Stat -no noticeable gain
TR MAF Ends - little to no gain
TB By-pass -no gain
Bump-stop mod - little gain
Pro 5.0 -no power gain
BGRM -what is ths?
NGK TR55 -no noticeable gain
FLP Headers & ORYP - - some gain add 17rwhp

Now lets assume that your 2002 makes the same as mine on the dyno bone stock..
That puts ya at about 316rwhp
Add the lid and you are at 323 rwhp
add the filter and you are back to 320rwhp
now add the headers and 337rwhp
when you get the pullies 342 rwhp seems about right
Finally tune it all.. if that is possible with the Predator then I would guess at 347-350rwhp..

All your other mods may or may not help your HP any.. Your 1/4 mile times should be decent since you may be able to get the power down but again I see another person that didnt research each part as he added it. I can understand why people do it but I myself wont ever just mod a car again.. I will only do each mod and test it to evaluate if its worth it.

When ya finally get to the track let us know. .If you get to a dyno bring this tread back up and post your numbers..

Good luck..
(my guess is that you can be in the 12.8's with good driving.. got to remember that WS6 is a heavier car and you have added weight with all the parts and suspension add ons..)

 

see sig....2002 Z28.

Lid and Hooker LT's, ORY, and Loudmouth are my only power mods...and it need a tune BADLY. My dyno graph is spiky as a **** (I dyno'd with a few stock 01 and 02's that day and NONE looked like mine)... see?

 

are those numbers sae corrected?

 

Yep they are.

 

why ya think the numbers were so choppy?
here is one of my dyno runs
have you had it tuned since?
I suggest to everyone that you do simple mods on the dyno and rent the dyno out for the hour... do a bunch of runs to get good consistant numbers..

Good track runs tho..

 

Nah, I havent had it tuned...been waiting to do a cam first Funny, though, one of my good friends owns and runs the local dyno/tune shop.
I have no idea as to why the curves are so spiked...when I made my pulls, I didnt get a printout or even ask to see my a/f ratio, and I wish that I had. I know I have a TON of audible knock though, and that is my only guess as to what's up.

 

I was thinking around 360 rwp. I do have a g-tech and according to that i read I have 364 hp. Don't know if that means at the wheels or not tho. The only thing is I have not messed with is the A/F mixter with predator. I does have the base tune installed. I'll just have to take it in for a dyno.

Thanks for the replies!!

BTW, BGRM means Brain Green Ram Air. It takes out the baffles on the WS6 hood and seals the airbox to the hood.

 

My TA,
-borla catback
-gutted cats (yes, the gain is noticable
especially up top)
-TB-bypass
-Lid
-Ripper shifter

Dynoed 331rwhp and 334 rwtq

Best run, I believe I had a 2.3 60ft time, (bald Good Year GSC's) ran a 13.25 forgot the mph, and lost my slip, that was my best time, but I can run 13.5 all day long without even trying. Slow, but it'll do for a poor college student.

Buddy with the same setup on Nittos Drag Radials in a Z28 same year as mine ran a 12.9. (shows my crappy launching capability)

 

a good idea, find a freind willing to lose that doesn't mod his car any. i found one with an 01 and every new mod i put on i see if i've pulled away from him more or less. ported/polished maf ends i lost a tad bit.
