Ran my 92 RS last night at Atco, NJ and just couldn't get in to the 12's. I was hoping that the 150 shot that i just installed would push it into the 12 second index but i came up just short at a best of 13.060. Info is below. Suggestions please!

Without 150 shot:

R/t: .363
60': 1.986
1/8: 9.043
1000: 11.82
1/4: 13.98
Mph: 97.46

With 150 shot:

R/t: .293
60': 1.768
1/8: 8.33
1000: 10.89
1/4: 13.060
Mph: 103.78

 

DETAILS! Whats the rest of the combo?...ALL OF IT!

 

150 shot only got you almost a second and only 6 mph? figured it be higher than that and quicker ET wise with 150 more hp

your 150 shot time looks good tho for the power at 103mph. My 12.95 run looks like that sorta. 1.71 60 foot, 8.21 1/8 , 10.79 1000 foot, and a 103.8 mph trap speed.

 

350 bored .030 over, vortec heads, gm aluminum intake, comp cam - .425 intake lift .440 exhaust lift, edelbrock shorty headers, flowmaster super40 exhaust, 2400 stall converter, shift kit, larger TBI injectors, 3.42 posi rear.

need any more details?

 

whats the duration on the cam? and compression?

hows the tune with and without the shot?

 

Duration: Intake - 252 Exhaust - 260 (if im reading my cam card correctly)

Not sure about compression

Tune is very good.

 

thats a pretty mild cam, so the n/a time seems ok for the mods. Its a TBI car still correct as i seen TBI injectors listed

I'd be happy with those results on motor for now. How heavy is the car? your gonna hit 12's with the shot with a little better launch and good air/weather. YOu probly could use more stall but with the shot, that 2400 should act like a 2600 or so.
Keep an eye out on the density altitude and air temp/humidity. Track that information and run when it looks as good as it will get in your area and you'll see good times

 

assuming you have at least 9.5:1, swap in a bigger cam (like Comp XE268) and go carb... you'd easily run 12.80-13.0's on motor and 11's on the 150 shot.

 

yeah i was considering a carb swap a little bit ago actually. thanks for your input

 

I'd be really surprised if your injectors weren't going static at ~4500 rpms. Are they 454 injectors?

 

i believe so. and what do you mean by static?

BTW i checked the nitrous jet today and it is a .047 jet which is a 100 shot i believe not a 150 shot.

 

3.73 gears for sure will help get you there!

 

What do you got for a transmission 400 hp dont mean jack if your transmission sucks.

 

700R4, stock except 2400 B&M Holeshot converter and B&M Shift Kit

 

100% duty cycle, open 100% of the time. Meaning that once they go static it just keeps getting leaner and leaner.

 

Do you have a bottle heater? Did you keep track of bottle pressure during the runs? When did you start spraying?

A 100 shot on my 2000 netted me .9 and 8.5 MPH on a very hot & humid day. I picked up 12-13 MPH on a 150 shot, picked up less than a second because of wheelspin.

 

bringing this back from the dead,

no bottle heater.
pressure at around 900psi
nitrous is activated at WOT
Times posted above are for a 100 shot not a 150 shot (typo)

Picked up 6mph and .92 ET on a 100 shot.

What should i be expected to run with a 150 shot? (planning on running it next week sometime.)

 

With traction, you "should" see another .3 -.4 on the bigger pills.

 

thumbs up for the quick reply.

anyone else out there?

 

What do you have for a suspension setup?

 

u need to go carb. u'll pick up .3-.5 just off that i think

 

spohn rear LCA's and Panhard rod, KYB gas a just shocks. Thinking about buying some LCA relocation brackets to help with the 60'. getting some spin off of the line. see for yourself:

hard to tell in the dark, but LCA relocation brackets help bigtime

 

What are you using for tires?
