I dyno'd the car today with the 100 shot and it gave me a 100 rwhp but the car was running extremely rich.
We put in the 150 shot jets for Nitrous only and it was still off the scale.

Does anyone have the jet numbers for fuel and Nitrous for the 100 & 150 shots????

Thanks

 

NOS quotes 55N/42F for 100hp, 70N/53F for 150hp.

What sizes were you using, and when you say it was running rich, how were you measuring that, and what kind of numbers?

I'm pretty sure the jets for the TNT system will be different.

NX jets are different then NOS jets. I would say go to TNT's web page and maybe you'll find it there.

 

I was on a wide band 02 dyno. The AF ratio was lower than 10.
I've looked on the TNT web site but found nothing.
The TNT jets are different because there are two nozzles in the TB Plate

 

I spoke TNT, It looks like I'm using the right size jets.

Has anyone else had to jet down the fuel jet to get the right AF ratio?

 

I went to TNT's shop a while back and spoke with Jamie about why he runs his kits so rich compared to others. He basically says that he does it for safety. He knows he could tune the kits for optimum power by running leaner like some competitors do, but his thought is to just put a bigger set of pills in to get the more power. You might be able to get another 20rwhp from leaning out the 100 shot. But at that point, why not just put pills in for 125hp?

 

HI,

Thanks for the reply.
I put in the 150 shot jet with the 100 shot fuel jet and it was still very rich and I only gained about 15rwhp and he says the 150 shot is good for about 162rwhp.
He advsied me to try the 75 shot fuel jet and se where that put me because my AF ratio was lower than 10 on the Wide band dyno and should be at 11.2-11.7 according to him.
He gave me a couple other things to check but I have a very good tune on the car NA so I don't think there are any other problems.

I suprised no one else has had this problem. But I haven't talked with to many people who ran their cars on the dyno with this kit.

 

I run 150 nitrous and 100 fuel on my tnt and have 11.3 air fuel ratio. on the o 2's it avg 925. using the listed jets it was so rich it was off the scale. putting in the 100 fuel gained and avg 1.5 tenths on the et and doesnt pop through the exhaust as bad when I shut off the spray after the traps before I come off the throttle.

 

What size jets are used for the 100 and 150 shot on a TNT kit?

 

55N/42F and 70N/53F will be running extremely fat, and you are wasting lots of nitrous. I'd say 55/32 and 70/40 would be somewhere close to running right. but that 70/40 is 220fwhp...have fun with that.
