Thread: 1/4 mile times of 4 door gtp's

i am just wondering what people are running in their 4 doors and what mods they have done .

My best so far is a 12.4 @ 110mph... That was before I did the intercooler. I am actually going to the track this Sunday, but don't have my hopes to high. I had to redo my tune, and it is not quite were I wanted tit o be. I am running an S1X cam, Gen V, N* tb, S&S Headers, 42.5 lb injectors, ZZP S3 IC, and ZZP tranny with 3.29 gears. Plus all the little supporting mods. I also use slicks at the track.

steve miller went 12.08@111 in my 2000 sedan a couple years back. he had a intense stage 3 head and cam package...no IC. he had slicks and was running a gen 3(i dont think it was ported but could be wrong on that). almost no suspension work and before fine tuned custom PCM tuning

most ic'ed xp cam guys would die for those times.

with under 100lb difference between coupe and sedan i hope you were not expecting alot different 1/4mile times. the only bad thing about the sedans is the weight distribution, it is more centered and to the rear then the coupes
im guessing this is due to the rear windows,rear door panels and B-pillar.

no not looking for a huge time difference . i am just a new owner of a gtp and am just wondering . thanks for the info fellas .

you might be right on that fish...i could of sworn it was on a gen 3, but now that you mention it that does sound kind of right.
too bad that car is not still built

I am right.

ran a PB of 13.19@105.36 at cecil county dragway earlier in the month. stock bottom-end, and mainly bolt-ons with a 3.2 pulley on street tires. i'll have to make my sig along with my current mods.

Fish im almost positive your wrong. It was an unported gen 3. Because he was arguing with someone a few months ago and posted his whole mod list and i remember seeing that. He was arguing with someone trying to show how his car was superior for what it had as usual.

found it. The right side are his mods and the right is animuls mods on his lumina.

Advantages have been put in bold. Seems pretty even to me actually.

Intense stage 3 heads - home ported heads flow benched 10% improvement over stock
Intense Stage 3 cam - Stock reground cam .512/.512 total lift
TOG headers - home made headers 1-3/4 inch primaries
stock stall, stock trans - stock stall, stock trans
STOCK throttle body - ported L67 tb
STOCK gen 3 blower - Whipple 2300ax
892 ft altitude - 1300 ft
3520 lbs - 3600 lbs

FIXED

I didnt have a gen v, converter, or ls1 tb for that run. The car was driven 2.5 hours to the track and raced on the same gas it pulled in on, 93 octane.

Straight from Millers mouth when I talked to him on Wednesday.

"The car ran 12.5s with a stock gen 3 and TB. The car ran 12.0s on a gen V and LS1."

I was there when he put the car together.

Actually, last time I saw Miller race it, it had the Gen V and no IC...

Regardless, it was still a quick 4 door.
