Slow Hemi :(

It’s like the 1980’s all over again. Remember the Buick Grand National and even better the GNX? With a turbo V6 they annihilated everything on the road even the Corvette. Drove them nuts. Good times.

Yes. I had 2 GNs back in the day. They made a lot of folks mad. And yes, I should have never sold them. With that said, those cars spent their far share of time getting worked on at the dealer. The 6/60 powertrain warranty was used quite a bit.

I'd bet that was transmission or egr issues, not the engine itself. Everyone one I knew back then that had GN's or GNX's had trans issues. That 200R4 was trash

Hmm, Can the Op post your times? Have a LOT to say on this subject. Way beforet he days of Hemifever and good tuners, I did drag race 101 on my truck, 2003 5.7 3.92s short bed std cab. All times were recorded @ Houston Raceway outside of Baytown, TX (RIP). Truck would run 15:60s New. Got it to 13:80s with Just the following Mods: removed Hemi Hat ( heat soaked, High IATs) Home Depot CAI w/ Amsoil dry Cone filter,
Superchips Tuner, I know but NOTHING else available ( got one of the first in Texas ),
Removed tow frame and installed roll pan, Thankx F150 but that's another story,
Leveled the truck
Installed 28 inch 17s, 20s weighed in almost 90#s each, 17s on aluminum wheels were 44#s
Battery in bed
Drag shocks ( Modified Chev units)
Torque Management Mod
Engine leash
Home made traction device (reverse pinion snubber)
Full Stock Exhaust, still to this day oil pan, valve covers, and the Intake Manifold have Never been off.
Ran 13:90 on street tires 13:80s on the slicks
All of this was Documented on Dodge Truck World before it went down Also RIP, That resurrection did not succeed.
This is getting too long, race prep, before I leave:
Remove Tail Gate and spare, remove front sway bar bushings and leave bar, conserve time and work. Race weight was 4720 with me in it (avg),
W/ 1/4 tank of fuel. Those times were @ -600 density altitude.
As I am out of state I will attemt to find the pics when I get home.

My best time currently is a 14.6 with a 6.6 0-60 time…the next two things I’m gonna do is drop 20lbs off each tire by going to a lighter tire and wheel combo but still off-road (unsprung weight) and then install the vararam intake.. those two might shave 3tenths off the 0-60 and a half a second off the quarter mile if I’m lucky. For comparison the stock f150 tremor with no modification does 0-60 in 5.8 and 1/4 mile in 13.8….

Lighter Wheels and Tires were on of the largest factors in the drops of my times on the 03, In my case I used the 7lb for every 1lb removed from the rotational mass rule. 20lbs X 4 = 80 X 7 = 560 lbs effective Mass. That alone should be worth .5 sec. Some use a 9lb factor but 7lb was more accurate in my times. My truck has the 22s on it and really would like to lose some of that weight but I REALLY like these wheels, soooo.
Keep track of your density altitude when you go to the track (or on the dragy) A difference between +800 to -600 would be the difference in my running times of 14.40s or 13.80s. The stock tremor mentioned above probably did not list the weather in which they garnered those times.
In my case on the CAI, I made my own Ghetto HomeDepot CAI out of 4 inch sewer pipe ( was just an experiment but worked so well I kept it). Used an Amsoil Dry filter on it. It was worth 3 to 4 tenths at the track. Did it give me a Fantastic HP gain? No, but it dropped IAT temps to within 5* above ambient temps, whereas the Hemi Hat would remain heatsoaked even at Hiway speeds.
Have not done much to the Hurricane but if I do Probably will not post it here. Dodge spys are everywhere, and I was blackflagged for my performance mods, dealers would not even honor the recalls. Did not matter as I would not take my truck back in to the dealer except for something catastrophic.
Good luck!

Thanks for the info and I will report back on my results.

Good point about the tremor, when I’ve looked at videos online also the best times I’ve seen real world are mid 14s so I’m skeptical about the official posted number for that truck

one other thing is I’m having to stay in 4wd high when doing all of my runs which might be contributing to some increase in drive train loss. My roads around here are crap I guess or it’s the tires lol, but even when I try to ease into it in 1st gear 2nd it breaks the tires loose if I could get onto one of my local drag strips I could probably do a proper 2wd run, during which I’ll even shave off a tenth maybe by running on a 1/4 of a tank of gas and removing the spare tire

I get it’s not a race truck but I’d like to atleast feel like the v8 can still hang with the new stuff
