My mods....thunder racing 220/220 cam, longtubes, weiand intake,85mm mass air sensor,ported throttle body, fasttoys ram air, and a racetronix fuel pump. New rods pistons, and had the crank turned. Is it safe to run a 150 shot on this thing? I tried it twice, and the car ran fine, but it ran kinda hard,(the rearend) took the hundred shot well, but would i be pushin it if i keep runnin the 150? 6.84 on the 150 through the 1/8 mile.

Wet or dry kit?? I would get rid of the MAF if you gonna use nitrous or at least make sure you get a tune. A 150 wet shot should not be a problem be sure to get colder plugs (NGK TR6) though.

6.84, I dont think so, especially with a cam that small.

 

What do you mean the car ran kind of hard?
What tuning done?
M6 or A4? If M6 I imagine your clutch is not going to like it at all. If your A4, get a TC. The rear is a weak link. On an A4 I wouldnt expect the rearend to **** out on you, however if you decently hooked an M6 with a 150 shot, your clutch, rear or both aren't going to like it too much.

 

it's an a4 with a 2800 stall (need a bigger one). But it felt like it wanted to break when i left. My torque arm is banging the bottom of the car now. Ive changed the mount twice already. And the car has been tuned. Not really worried about the rearend. Just dont want to blow the motor up. And it's a dry kit. and all i did was remove the screen off the mass air sensor
