How much nitrous on stock internals?

[H8IT4U]

Recently I sold my 99 Gt to a friend along with my nitrous kit. I have been running a 95-100 shot on this car for the longest and hitting the mid-12's with no problems. Talked with him the other day and he is changing the jets to between a 150 to 175 jet! Is this safe? The car has all the bolt ons but still has stock internals. If this is not safe what is the limit for this car?

i would consider getting a forged bottom end imo

I suggested the same, but i need to know how far can he go without damaging the engine?

stick to a 125 shot WITH a dyno tune. 150 is just asking for it IMHO.

I spoke with the people at NX and they said 150 was the max but does that mean safe?

i spoke with a friend of mine last night that has a nitrous kit on his 02' GT and he is running a 125 shot with a real good dyno tune.

Whenever you run nitrous, it would be wise to save some $ for a forged bottom just in case. Personally, I wouldn't go over 125 max.

well, with the intakes, the more shot the more fuel pushed in, so you will have cylinders getting varied amounts of fuel if you are using a big shot(175+) i have seen first hand that this will kill the best of motors. so even with a built motor, pushing more than 150 is just asking for issues. but with a properly setup NA car and a 150 kit mid to high 10's are pretty attainable

Has he run any numbers: dyno or track?

What kind of times do you think the 125 shot would run if done right?

 

[03ghoststang]

i'll ask him later today on the numbers, but i know this year it will be the first time he will run it at the track

i run a compucar 125 shot, untuned, range colder plugs..have pushed a good 40 bottles of n20 through the car and she runs great, people say you have to have a tune, but never got one and she runs just fine...but n20 is tricky, its like the hot chick with an STD...u wanna hit it, but are afraid of the consequences...i personally wont go over a 125, makes all the power i need and gets me down the track plenty fast..

60' 2.03
330 5.13
1/8th 7.72@95

A 100 shot could be risky with out a proper tune. A 175 even with a proper tune is a ticking time bomb. The stock internals can only handle so much.

LOL, thats the EXACT same ET I got...ummhmmm N/A. It appears that the car was laying over on the big end, you had me by over a 1.5MPH in the 1/8....then I came back and got almost 2MPH on you in the 1/4. Whats up with that . Nice time BTW

I wont comment on the N20, it gets me into trouble when i give my opinions .

colder plugs, bottle heater, purge, blowdown tube (to legally run at the track), FPSS, bottle pressure gauge, window switch/WOT switch, dyno tune to check A/F.
