the only car I tested both ways was the 85 "JYD" w/355 13.60's motor and 11.90 ](movie) on a 150 nos carburated powershot with the TPI (#5151) jets for my carb intake converted to fuel injection. remember we race at 6000 ft thats why I get more than a second for the 150 shot.

These are my old times from 1999:
Motor: 13.3 at 108
Motor and 150hp NOS: 12.2 at 122
The nitrous run was from about 40mph on up (2nd + 3rd gears).
The car is tuned perfectly and probably runs in the mid 12's at 112mph or so on the motor. Add the 13mph from the NOS on top of that and you get 125mph or so in the mid-low 11's.
Don't forget the faster the car is, the less it helps. This also applies to modified motors (NOS is less effective than for a stock motor). It may add 100hp on top, but may add 175lbs o'torque down low, this is why the ET is helped so much compared to something like a vortech or paxton. It also makes your tq converter stall higher because of the increased bottom end.

Yeah I thought the same thing. It came out of #4 hole.
None of the other pistons look bad. Could be just a bad slug went bad after so many miles. I only threw about 15 bottles using a 100 shot at it.
Not to worry a new stroker is on it's way.

Looks like alot of you guys are getting an additional 12-14 mph on 150 shots and 8-10 mph's on 100 shots in the 1//4 mile. Can't wait to get mine on the track as soon as it opens I'll be running the NOS #5151 150 shot on a GTA that went 13.9 @98MPH. Think high 12's are possible??

I don't have any new times yet. I'm still waiting for the heads.
That piston looks similar to mine. I understand the ring expansion and my new motor is gapped accordingly.
BTW Mine was a stock slug and had 115k miles on it before I flogged it. The pistons haven't been out since they were installed by the factory.
Tom: That one is a TRW?

yes, it is trw, they are my favorite little subjects of abuse, my little mistreated anvils. right on for you on the ring thing. at the risk of opening a can of worms we run backwards mix of stock style ductile iron and moly rings on our big nitrous motor.

I love my broken parts collection. Good bench racing subject material.
stockmstyle ductile iron ????
There's enough worm's here to go fishing.
This must be a race only motor that you run right away after rebuild.

AAAAARRRGGGHHHHH!!!! 13.7 @97 150 shot, spun all of first and second gear on heated BF drag radials @14 psi. Crazy torque baby!Engine pinging at end of 3rd gear due to high heat range platinum plugs. less than 600 psi in bottle(no bottle warmer at the time).

my best time was 13.9 all motor at 97 mph with 1.90 60 ft.. it's a world of difference with the bottle warmer and 900 psi with the corect heat range plugs.

It's been a while but i finally got the motor together (ZZ4 Block, AFR 190's) and ran N/A with a 13.39 @104 and 11.97 @113 on a 150 shot with the bottle warmer and 1000 psi of bottle pressure. These runs were on Mickey Thompson ET Streets.

Upon blowing up my good block trying to make a pass
with the charger and a 100 shot - on that pass I ran 10.32
@ 133 with a 2.1 60 ft (lots of spin) should have gone high 9's.
After that pass I replaced that block with a stocker out of my old truck,put on my heads,cam and 100 shot only (no charger)
10.89@ 125
