to much torque for the stock rods to handle..bent and/or broken rods

 

Bump for the new guys.

 

lol, thats a serious bump.

Jetting is dual 37/22 for now, af is holding steady around 11.2 on bottle. No dyno or track times as yet.

 

Ran a 13.1 at 111.9

 

^ Time slips? With that trap, you should be at least mid 12s on street tires.

 

They are at home, i'll try to post them later on.

60' that run was a 2.15 or so, I got down to a 2.05 later on but I was not spraying anymore, I ran the car 11 times that night, and the spray runs didn't feel like they had the power they should so i stopped spraying. Went a best of 13.56 on motor with the 2.0 60', at just under 104mph.

 

8mph pick up isn't bad, especially considering the hot weather you're probably in. I trap around there, too, in TX. We can't expect to see similar times as the northern drag racers. Another thing you might want to take a look at is your fogger position. Either way, you're running 13s with a 112 trap, which means you need more practice.

 

Yeah, it was in the 80's at night lol. I don't even try to spray the car until im firmly into second gear, I got my lauches quicker at the end of the night, if I felt like spraying again the car had a 12 sec pass in it, i dropped a full tenth off my 60' which is usually good for .2 in the 1/4. Another time, no rush. Preferrably with HFC's or something, stock cats are killing the power.

Nice. I wish I can rev out to 7.5K rpm. What exactly is cut off (fuel, ignition, etc) when you hit the rev limiter? I'm afraid of hitting the rev limiter on spray since I don't exactly know what is being cut off.

 

Fuel is being cut my window switch is from 3500-6800. I'm a DE with cams my rev limit is set to 7200 the tach reads 200-300rpm higher on DEs.

I don't spray through the shift 3rd gear in my tranny doesn't like it.

 

Factory limiter cuts fuel if you exceed the throttle plate closing limiter. If it's been adjusted, you can choose what you want. I know with the COBB you can set a throttle rev-limit, a fuel limit and a spark limit. From the factory they are staggered in that order.

BTW, the car on the spark limiter sounds nasty with a loud exhaust. It's a very rapid limiter, sounds like a machine gun. Quite sexy

 

If only the fuel is being cut off then, I guess it's good I never hit the rev limiter. After all, you're spraying a wet shot, which has fuel in it. So, a spark will lead to combustion of the nitrous/fuel mixture + air from intake but without the proper fuel added by the injectors, leading to a lean condition.

 

Good thread ... Bump for good info

46N 26F / 93 / 0º / No dyno / 12.1 / 12.9 @ 107mph

57N 35F / 93 / 0º / No dyno / 12.8 / 12.9 @ 113mph (spin fest LOL fml)

this was a stock motor

i have a built motor now on direct port and Q16 sitting on 28" slicks so it should be interesting

Nasty trap speed for sure, car must be strong on the highway.

I am going to the track next week wendesday, i'll post up times on my current setup.
