i have an 06 type-s w/ fujita cai, hondata img, and a wet 75 shot. bottle pressure on the 1st run was around 990psi and the 2nd run 950psi. jettings are 42 nitrous and 24 fuel. 91 octane and 3 gallons of 111 octane. this was on a mustang dyno.
here's the graph for the all motor run, afr was measured with an o2 sniffer on the tailpipe so dont mind the lean spike at 7k rpm.
graph for the nitrous run, crazy vtec dip, i'm running very rich up top, dipping into the 10's.
Numbers seem low. I have I/H/E, IMG and was spraying a ZEX 75 shot wet kit on top of all that and hanging with Buschur Stage 2 EVO's on the interstate.
Based on power to weight ratio's we estimated my car to be around 250-260whp in order to stay even with a 325-340whp EVO. I also used a hp calculater that takes your 1/4 mile trap speed, time, and vehicle weight and computes the amount of hp it takes to run that. It came out to 260whp. So I would say thats a very reasonable guess for my car.
As far as tuning with a 75 shot. It would help, but I don't feel it's necessary. I am basing this on the fact that I ran 6 bottles through my car with no problems. However I want more power so I sold the ZEX kit and I'm saving up for K-pro and piecing together a custom dry kit so that I can run a bigger shot and possibly dual stages. You can use a wet kit with k-pro, but ZEX's Brain module makes things complicated, where as a dry kit controlled by k-pro is about as simple as you can get.
^ easy. A wet shot brings its own fuel to the party through a nitrous fuel line. A dry shot need kpro to add additional fuel through the injectors since it does not bring additional fuel through the nitrous line.
no kpro. a wet shot is safe to a certain extent. the higher shot you go the more likely detonation will happen. with my 75 shot im running very rich and with no detonation because of 111 octane. if i used straight 91 octane i'll be detonating. if you have kpro you can manually retard ignition timing so you don't have to run race gas. understand?
Yeah I can say that my engine would have blown a long time ago if it wasn't for kpro....My car has 80,000 miles and a year now on 100+ shot and it's still making right around 300whp
NO we aren't saying get kpro because it will help you make more power...It's because kpro will help you get more power safely and without blowing your motor...Plus it makes life alot easier
kikwear002: How many times did you spray a 75shot on a type s with no kpro?
