Default Finally got some dyno numbers with N2O

Got the car retuned last week and put it on the dyno to make sure my AFR was safe with the spray. The mods are listed in the sig.
NA:
HP: 327
TQ: Something like 478 or some crap. Dyno had trouble with the big stall

N2O
Hp on 100 shot: 407
TQ: 430

Wasn't on a full bottle, which might be partly to blame for not picking up 100 peak hp, but saw 100 increase through most of the powerband. It was interesting to see that I went down from 349 to 327 hp with the switch from a Yank 3000 stall (felt more like a 2800) to a fuddle 3600. I'll try and get to dyno posted later today so I can have the actual numbers, as these are just what I remember.

I'm surprised you went from Yank to Fuddle, I'm looking to do the opposite.

Got the Yank cheap and was told it was a 3600. Turned out to be much less than that and I could hardly get off the line with any power. I couldn't afford to buy a new Yank on my college student budget, so I went with a fuddle and have really liked it so far. Went from 1.9 to 1.6x 60 foots.

+1 most folks stick with or either go to the Yank. Either way nice numbers and it's good to see how a stall can play around with numbers on the dyno.

Ran a best of 12.4 last summer NA, but won't be seeing the track anytime soon due to lack of tires.

I think he meant ignition heh

Hopefully you can get back on the dyno with a full bottle to see what it'll do. I thought 100 shot on ours was closer to like 115-125hp actual gain (on the dyno).

No idea. It was in the summer heat at KCIR. Hoping for 12.3s at 110+ this year.

Auto cars with after market converters are some what misleading, most the big internet horse power comes from six speed 10 bolt cars.
