V-10 Killer

Well, the last 10 days has been hectic. After getting 600 break-in miles on the car, and dropping it off for a few days, my car decided to puke the brand new Walbro 255 intank pump I put in 2 months ago (2nd one I've bought this year...). Sooo, we sumped the tank and installed an Aeromotive A1000 pump. Only fueling issue now is that I need a check valve to keep the prime on the pump after it shuts off. Anyway, on to details:

1998 Pontiac Trans Am
LS2 402 stroker from SDPC
-14cc pistons
ETP 245 Heads w/59cc chambers
Cometic .051" head gaskets
11.2/1 SCR, 8.05 DCR
Comp 242/248 .611"/.615" 114+2 LSA cam installed 2 degrees more advanced
F.A.S.T. 90mm intake, SDPC 90mm TB, SLP 85mm MAF
KOOKS 1 7/8" Longtube Headers
KOOKS stainless magnaflow catted y-pipe
Borla exhaust w/no restrictor plate
FLP Level 5 4L65E w/TCI competition 3800 stall converter
Strange HD driveshaft
Strange 12 bolt w/3.73 gears

Tuning and power pulls were done on a Mustang dyno (1750-de I believe) in 85 degrees and 50% humidity. Final numbers were 459 rwhp, and 407 rwtq. The tuner believes he could have squeezed a bit more out using a better MAF, but for now I think that's pretty stout. The graph shows over 400 ft-lb from 4500 to almost 6000 rpms. He advised me against spraying any nitrous runs until I remove my cats. They were already glowing, and got hot enough to melt the insulation off my fuel pump hotwire kit power wire, from behind the heat shield! Looks like its also time to relocate the path for my nitrous supply line too LOL. Also found out my wideband is significantly off and I was adding a LOT more fuel than I thought I was.





Now, assuming Dynojet numbers would be ~10% higher, that would put me over 500 rwhp, and around 450 rwtq. We have a local car show in two days with Livernois portable Dynojet showing up, so I'll get SAE Dynojet numbers then for comparison.

Before the tune, in good air, I managed a few 11.1xx and 11.2xx shakedown runs. Hopefully now, I can get back to the track and squeak off a 10.9xx or maybe better on motor. I'll know in 2 weeks.

Awesome congrats!!

Very stout. Based on my experience with Mustang dynos, you should be well over 500 rwhp. Very impressive, especially through an automatic!

Thanks Guys
And thanks again Patrick for the advice on advancing the cam.

Nice.... Congradulations on your new found power and keep us posted on what it runs. I am sure you will be well into the 10's...

Very stout numbers, I just dropped my car off there Tuesday and saw your car, looks bad *** and definatly makes some major power.

Thanks! Was that the WS6 with the chrome bird decal on front and a plate something like USMUSCLE. If so I saw that, very nice car. Didn't get to see under the hood, but maybe some day.

Yeah that was mine I'm sure it won't hold a condle to your car at full potential but its not bad for stock cubes and H/C in an auto.

Awsome numbers. One thing about a mustang dyno, is you have to be careful on assuming that the dynojet is 10% more. That will only happen if the dyno operator is using the mustang dyno the right way. I have seen some shops take the load off the mustang dyno and change the calibration to match other dynojets. So just check into that. Eitherway, those are awsome numbers for an Auto.

that tranny, converter,rear end, and mustang dyno are robbing a lot of power. so u will be high 10s low 11s easily with a good 60ft

Nice numbers!

Thanks everyone. I'm guessing with the car weighing in at a 3600 lb raceweight, and the fact that every time I go to the track it's always 90+ and humid as hell in cornfield country, I'll be doing backflips if I get the car to run 10.7's. I know tons of people have done more with less, but I'm happy just keeping it "for the fun of it"

V-10, what timing did you end up with the ET heads? Nice numbers!

V-10 Killer

iTrader: (22)

After all the other tuning, we only did 2-3 power pulls and wound up leaving the timing at 28 degrees. He said that's where he's had the best luck with ET heads...

There! First post updated with scans of the dyno sheets.

That torque curve looks freaking awesome! That thing must be a blast to drive around town.

We couldn`t run more than 22 degrees timing on my set-up. They said anymore and she started loosing power. I wonder what gives??? with mine!!

V-10 Killer

iTrader: (22)

Look at your torque versus mine though. Yours is certainly impressive. What kind of times are you running with that car with and without the 200 shot?

Your motor run wasn't unlocked, was it?

I got 472rwhp and 506TRQ locked on motor. We didn`t lock the conv on spray because it was new. But I feel over 700rwhp locked! Next dyno day I go to I will see now that I`ve got some miles on her!
