My car: 2005 GTO M6
LPE CAI, Kooks 1 7/8 LTs (no cats), Flowmaster mufflers, TTP tune
made 363rwhp/358rwtq SAE and ran 12.7@112 before the LT headers

His: 2003 Cobra 10th Anniv.
2.8" upper, JLT CAI, MAFia, KB throttle body, catless x, custom dumped catback, solid rear, JLP tune....makes 47x rwhp 48x rwtq

I lost obviously, Ive driven his car plenty of times and knew how quick it was. Its one of my best friend's cars and it was just a quick run last night from one meet to another. It was just him and his girl in his car but I had my girl and another friend in the back seat. Both of us were in 2nd gear, 50 mph, I honked it off and made sure to go right on the 3rd beep. By 120mph he had about 4 cars on me. My other buddy with a mystic 04 with upper and lower pullies beat me worse, so I'm trying to set that race up between the Cobras.

Im not exactly worked up because I lost to another friend's Cobra last night in the GTO because I've yet to lose to one in my WS6 , which is more so my "race" car. I (barely) beat this same 03 Cobra when I was cam only/full bolt ons and he refuses to run me since Ive added the new shortblock and heads, especially knowing I beat the 04 on this setup. Hes having a 2.8 KB blower installed early June but luckily for me I dropped my car off at TTP (the day after he told me the news LOL) and should be getting it back with 150+rwhp.

 

nice death, no shame in races between two buddies

 

kinda outmatched...guess you were hoping he missed a gear or something

 

yeah shoulda just nudged his rear fender a bit, he woulda slowed down.. or wrecked

nice death though

 

rubbin's racin'

 

Nah, just a friendly race. Plus I race anything as long as its a good road with nobody around.

 

'xactly

 

me too...as long as its not something rediculous like a 4 car masacre...jk

I do the same thing

 

Sounds like fun! Being safe and having fun, can't beat that. Honorable death!

 

It seems like your car should be making more then 363rwhp/358rwtq with your mods.

 

To the guy above me. He stated that those numbers were without the longtube headers.

 

Correct. Bone stock exhaust...cai and tune only for those numbers and track times.

 

nice runs...what's done to your ws6? just curious...

 

Go fast mods:
forged 347ci, PRC S1 243 heads, Cometic .045", TTP V4 Punisher Cam, SLP oil pump, double roller chain, FAST 90, NW 90mm TB, EWP w/ 160 T stat, ASP pulley, 85mm MAF, TSP lid, BGRA, Kooks 1 3/4-1 7/8 LTs, TSP duals, NX 150 wet shot, 42lb injectors, Walbro fuel pump, TTP tune, SPEC S3, built T56, Moser 12 bolt 3.73s, Full BMR suspension including K member, QA1 shocks, wolfe 6pt chromoly rollbar, weight reduction (no AC, no back seats....nothing too crazy)

 

Doah! My bad. I was thinking those cars had that much power stock.

 

M6 LS2 cars are usually around 345rwhp. My car only did 331rwhp SAE on TTP's dyno...then with just a CAI and tune did the 363hp/358tq SAE on the same exact dyno. I felt a very noticeable SOTP difference leaving the dyno that day. My car was a factory turd until it got tuned.

 

have you tuned it since the lt addition? it will make a difference. good death.

 

When I started reading the mods on both cars I knew who was gonna win... I'm sure you're not too heartbroken knowing your T/A would have killed that same cobra

 

If you wood get rid of the garbage flowmaster mufflers you might have won flowmaster is low rent lol

 

Nope. I have a cam only setup comming together so I'm gonna wait. I dont think the LTs threw the tune off too much, car felt a tad stronger when they went on.

Haha, exactly . I consider the GTO my "nice" car and yet I still win 90% of the races I get involved in around here.

I went from stock to straight pipes to flowmasters, the car has felt the strongest with the flowmasters. I've read theyre not a restriction as for example the flowmaster catback for F bodies.
