Spray on a H/C car Q's
 

I currently have my car tuned for an N/A setup. If I wanted to do a 100hp spray, would I need the car re-tuned to lower timing & bump up the fuel? Would this only be the case with a dry kit? Should I go with a wet kit for my needs? I will probably be spraying 150 in the future.
Anything I should know before going down this rout?
What rpm's should I spray at?

I was looking at the TNT 100 shot F1 kit, I kinda like that, any good?

thanks guys

I had my MSD window switch set at 3000 to 6800 and the rev limiter was at 7000. I had the 100 NX wet kit on my H/C C5 that had 427RWHP N/A and went 11.54 N/A and 10.64 @ 129MPH on the 100 shot. I didnt change the tune or timing and had no problems. If you are using the wet kit it will add its own fuel the injectors will not play a part in it. If you plan on going 150 shot you may have to change your fuel pump and take out some timing. I do not know what my timing was set at however. This was just my experience and my opinion based on my car, Hope it helps.

Yes that does help! What kind of setup were you running then?

You are suppose to pull back the timing a bit on the nitrous.
I ran a 150 shot on my H/C's and kept the timing the same. I made sure it was on the rich side when I sprayed.

What do you mean by set up???? If you mean nitrous it was a NX Express single 100 shot wet kit. If you are talking motor it was tea 5.3 S2 heads and a 224, 581 cam on a 112 or 114 im not sure. On a stock bottom end. :)

Did you blow the motor or did you just want more power? Is that why you went to the 408? I plan on spraying a 100wet shot on my stock bottom end H/C car, just wondering if it can take it?

I took the motor out it didnt blow. I wanted more CI and Iron block so i could spray more and go faster :devil:

HAHA, cool, I plan on doing that later down the line, just want some descent numbers for now.
