Default New Personal best in my 2003 Viper

Well I am smiling from ear to ear..Some of you may remember last week were I accidentally let my rear psi down to 17 psi and out of 10 runs I only managed a 12.2 at 121 mph off a 2.2 60 foot. I was disapointed but knew most of it was my driving...Well I went out again tonihght and had the psi at 21 in the rear and put in a full tank of gas to put a lil weight on the rear wheels. The result was my best night ever..


scroll to bottom for quick results


SORRY THAT NO TRACK IS AVAILABLE ON MY ISLAND AND ALL I HAVE IS MY CIRCUIT CITY FX2 TIMER...(always the same exact location a outstanding 1/4 mile spot that I have been useing for about 8 years now.......


1000 feet elevation
65-75 degree hawaiian weather

And with the same circuit city FX2 timer I have been using for 8 years

(tested at actual drag strip for accurracy and found that the 60 ft is 100% accuartae and the 1/8 mile is 99% accurate and the 1/4 mile is usually off by 1.5 mph and 1.5 tenths...But sometimes dead on)...

The following cars have been tested at this location useing my FX2 timer

-98 supercharged auto camaro=14.9 at 93 mph( best ever at drag strip=15.1 at 91 mph)

-stock 2004 auto corvette=13.3 at 105 mph(best ever at drag strip=13.5 at 104)

-stock manual 2005 nsx=13.1 at 107 mph( no drag strip runs)

-stage1 auto E55AMG=12.5 at 111 mph (best ever drag strip 12.7 at 110 mph)

-Mild head and cam auto corvette=12.6 at 113 (best ever drag strip=12.8 at 111)

-1999 Viper stock 410 rwhp=12.4 at 117 (no drag strip runs)

-1999 Viper with bolt ons/aem tune at 445 rwhp=12.0 at 121 mph (no drag strip runs)

it should be mentioned that at the drag strip we are lucky to get 3-4 runs were with the fx2 you can easily get in 10-15 runs in an hour


You can see on my first outing trying to learn the car I sucked pretty badly..LOL

2003 srt10 with roller rockers and kn filters at 459 rwhp

1-12.7 @ 114
2-12.4 @ 115
3-12.4 @ 116
4-12.5 @ 115.6
5-12.4 @ 115

Man this car SUCKS I thought...Littel did I know that I was shifting when that damn yellow arrow appeared and really to early at 5500 rpm's or so

Tried shifting a lil later
6-12.4 @ 117.9

And then a lil later

7-12.37 @ 119.0
8-12.25 @ 119.3

And then on my 9th and final run shifting right before red line I clicked off a

9-12.08 @ 118.9 1.93 60 ft 7.9 @ 91.3 1/8
0-60 mph in 4.13

Very happy with the ET but dissapointed in the 119 max trapps I called it a night

Went back at it again a few days later( KN filters and roller rockers) 459/492 SAE

I baby shifted on these runs trying to see if I could hit 120 mph trapps

10-12.77 @ 115.6
11-12.75 @ 118.1
12-12.43 @ 120.2

YEA BABY a 120 trapp..Not to shabby and I called it a night

Went back out on another night( kn filters and roller rockers) 459/492 SAE

Tonight I wanted an 11 second pass and was all buisness


13-12.5 at 115.9 getting warmed up
14-12.4 @ 117.8
15-12.26 @ 119.2
16-12.1 @ 120.5
17-11.97 @ 121.3 60 ft 1.97 7.9 @ 93.5 1/8 0-60=4.05 !!!!!!!!! HELL YEA best ever with kn filter and roller rockers

18-12.1 @ 120.2
19-12.1 @ 120.1
20-12.05 @ 122.2 ( highest mph yet)!!!!!!!!!!
21-12.08 @ 121.4

Then I called it a night...

( kn filters and roller rockers plus cat/muffler delete) ???rwhp???rwt...added the cat/muffler delete and went back at it


22-12.22 @ 119.6
23-12.13 @ 118.8
24-12.03 @ 120.6
25-11.95 @ 121.9
26-11.92 @ 121.7
27-11.92 @ 121.5

Kn filters and roller rockers plus cat/muffler delete and removal of rain baffle...rwhp??? rwt???


28-12.2 @ 121.9
29-12.1 @ 120.4
30-12.0 @ 120.5
31-11.88@ 122.3 2.0 60 ft fastest ever WITH LOTS OF 11.9'S AND 121 MPH TRAPPS TO BACK IT UP

well honestly it seems like removeing the rain baffle gave me maybe a .5 mph benifit....looks like I was 120-122 mph all night...but befor removing the rain baffle MY runs would be in the 119.5-121.7 range


Well it had been a while and I have added the viper specialty SCT tune/findanza flywheel/titanium exhaust/underdrive pulley plus still the roller rockers and no cats and KN filter with the rain baffle still removed..Now dynoed at 476/512 SAE.

32-13.5 @ 117.5
33-12.1 @ 121.6
34-12.3 @ 121.2
35-12.0 @ 121.8
36-12.3 @ 122.2
37-12.1 @ 121.9
38-11.8 @ 122.1
39-11.67 @122.7 60 foot 1.87 7.65 At 95.5 1/8 and 0-60 in 3.68
This was the best I have ever done period and it was nice to see the mods showing their face...

Next mod will be the revised BBK throttle body..Cant wait to test it out. hopeing for consistent 122 mph trapps with the ocassional 123 and 11.5

twins on the viper? damn dude. I'm trying to find another 76 to go the twins route. I'm at 750ish at 15 psi right now. that silver car was a cam only convertible with a 10 bolt. i was driving it so i would be able to make it home.

No I personally dont like TT's....Ill be around 600 rwhp naturally asperated..Maybe a 75 shot of juice for good measure on top for the kooling effect and that lil extra help in case your car is a monster

well right now it's only a single 76 and gets solid 11.1s on drag radials. I'm turning it up to 17 and trying for 10s. but i still have a 6 speed and stock shocks/springs. QA1s and ET streets will have me well into the 10s

Good runs...gotta love the track right!

I know little about Vipers. But I dont understand why a car with 47x hp and 5xx tq wouldn't trap higher. Is it the stock gearing or weight perhaps?

^This. I know we had our tiff's before but seriously why doesnt this thing trap closer to 125+? that much power with such a broad powerband I think would be a monster.

No disrespect intended.

probably the 19 or 20" wheels arent helping much for traction. plus the roads in Hawaii arent the best to put big power down.

Well the spot is at 1000 feet elevation and the wether is in the 70's and very humid. not great for drag raceing at all..

My friends 500 rwhp C6Z06 (mild cam and intake) only trapped a best of 123.5 mph at this location..My friends 620 awhp GTR only went 128.6 mph..Same testing gear and same location on all 3 cars..

Im sure at a sea level track in 60 degree weather with little humiduty they could all go 3 plus mph higher in the 1/4..

Suppossedly a stock 2003 viper is suppossed to go 121-123 and a stock 2007 Z06 is supposed to go 124-126 and a stock GTR is supposed to go 119-121 mph...

But it isnt always gonna work out like that..especially not here in hawaii were it literally rains every day

Good info.

If my dream came true I'd have a Viper next to my Vette in the garage.
