I'm very curious as to what a nitrous setup can do on the track. I've seen a few low 14s from a close to stock Civic Si, and a 12.2 out of a H22 hatch with a 100 or 75 shot. I'm about to do a nitrous setup and was curious as to what times people are getting with a nitrous motor setup.

Post up your info (engine setup, car/weight, dyno and/or 1/4 times) so others can see what setup works and how well it works.

 

92 si
b20 vtec
about 2400- 2500lbs
100 shot
11.9 @116

 

2700 lb prelude
65 shot, i/e
khumos
13.6@104.5
2.2 60'

 

1950 lb civic cx
d16z6 i/h/e 60 shot
22x8x13 slicks
12.8 at 103
1.89 60 ft

 

95 hatch 2250lbs
stock gsr
60 shot
12.5 @ 110
1.84 60'

 

Thats damn impressive.

 

ZEX 85 shot (dry!)
stock Z6 SOHC
20x8x14 MT @ 12 psi
2200 lbs with driver
1.816 60ft
13.09 @ 103 mph

 

I went 13.30's @ 106 in an EK coupe with a B18C1 I/H, 50 wet shot on 22/8/13 M@H's with a slipping clutch. The car only went 14.40's @ 93 on the motor(I'm guessing because of weight) and that small shot dropped it 1.1 seconds and gained 13 mph. Not too shabby.

 

1 sec and 10 mph are the norm for a 50-55 shot, even on a SOHC.

 

D16Y8 ZEX 75 shot
00' Coupe weights ~2700 lbs. with me in it
Nitto 555r Drag Radials
14.2 @ 94
2.1 60' Need Slicks....

 

when I had my crx with a b18c5 with jun stage 3 cams i did like 12.41 on the motor and 50 shot direct port I did 12.01 @ 117 mph spraying 3rd and 4rd.
On the dyno I did 200hp just on the motor and with NOS WAS 305 HP @ the wheels

 

How did you gain 105whp with a 50 shot?

 

92 civic hatch 2100 lbs
lsvtec ~ comp around 11:2-11:4
50 shot wet single fogger
22x8x13 slicks, also tried 24x9.5x13

1.702 60 foot
12.1 @110

at least 20 runs in the 12.2 - 12.3 range out of no more than 30 runs on N20


Regarding whomever asked how you would gain 105 whp out of a 50 shot:

When adding N20 to a combustion it not only produces more power, but its like a catalyst by increasing the rate at which the motor combusts. So instead of looking at what peak WHP n2o may add, think of the BROAD TQ and POWER it unleashes.

When i ran the exact same setup all motor, i ran consistent 12.9s. For kicks I first tried adding a single wet fogger from a direct port setup jetted for an 80 shot, hence becoming a 20 shot for a single wet shot. I ran 12.2s to 12.3s with only backing on the timing 2-3 degrees. The reason for such a large increase was that my car would have excellent launches, yet the top end lacked power. I used a b16a tranny, yet 4th gear felt like a snail. With the N20, the car pulled just as hard in all gears!!! I was using 22x8x13, the all motor issue probably would of been solved by switching to 20x8x14 slicks, which i tried and killed my launches.

The reason for such a small increase from the small 20 shot to 50 shot, is due to traction. Yes I was able to cut 1.702 60 foots, but I was still spinning off the line!!!

 

91 DX hatch
B16a n/a 185hp/120tq best1/4 12.97@103
w/50dry 217hp/165tq best1/4 12.53@109
1.84 60s on both runs
22x8s
NOS is no longer on the car

 

i believe the jets I was using was 26 NOS AND 18 FUEL

 

ON MY INTEGRA NOW i WAS USING JET 47 THIS WAS DRY i DID A 13.37 @ 94MPH
i BELIEVE THE SYSTEM FAILED IN FOURTH GEAR
on the dyno I tried jet #56 dry and I was too lean
so i did a single fogger wet setup with jet 56 for nos and 36 fuel
250 hp second pass blew the head gasket and the piston cracker well one of them did. LOL
ITS ALL BACK TOGETHER, but am just waithing to build a b18c5 with jun stage 3 again with some arp head studs. i would like to get in the 300hp range.

 

I believe the 26 nos jet with 900-950 bottle pressure should be 100 shot
Im running 28 nos 22 fuel with motor set to 50 psi of fuel.With the bottle pressure at 950 the run starts off good ,but by end of third gear,bottle pressure has dropped to 850,and the system then runs too rich.
Any suggestions???
With a 85 shot (22-16) the car runs 12.30 @116
All motor is 13.20@105

 

buy a bottle heater raise the pressure to 1100psi it'll run lean a little but should be fine.

I understand this, but it is still not likely that a gain of 105 peak whp would occur from a 50 shot.

couple questions for you:

1) how much whp NA?
2) what size slick on the 11.9 run with squeeze?

Hey you said nitrous set-ups.

Ahh the good ole days. Atleast I have a car that doesn't break now and have the rear calipers freeze up when on the highway. .

Definately good for some 12's on slicks.

 

well I guess the 26 nos and 18 fuel is a 105 shot.
it depends on the motor..
direct port is the best....
