D_MONEY said:there as a guy that sprayed s3 on hom and it worked for a little while. he had a 50 shot. i guess it made it through 3 runs on the dyno. then he took it to the track and went to spray in 3rd then it just popped. there have been a few that have done very little shots and were fine but anything over a 35 i would be scared. but i guess i cant talk much. i see 33deg of timing at redline and i still spray a 65shot. and next trip the the track ill be spraying a 100 so only time will tell for me.
D_MONEY said:yeah i spray on my regular tune. but i found that i could only run a 35shot without race gas. so when i go to the track i mix 5gal of 110 to about 2gal of 92oct pump. with nitrous on i spike 24psi. i also have wi running 100%meth. so far everything is safe. there is no knock but i havent upped the jet since i went to the 65shot. but its safe if you make sure you look at timing. and know your effective octane. with the wi and the 110 my effective octane is about 116 so im farly safe. the highest timing i see is 33deg and thats at redline when my boost have fell of pretty dramaticly.
Great post with great info. I can never comment on anyone's spelling and stuff. That would be the pot calling the kettle black. As you can see, my mods are pretty simple, If I stay the nitrous route I would look to optimize S1 and the nitrous. Again good post. Thanks for the info.D_MONEY said:well you could but if your boost spikes over 18.7psi then the pcm will pull timing. just a little food for thought das mopar when he ran 10's on s1 had a safc and was spraying. so was whitemoutain on his s3 car when he broke 10's. so if you plan on running spray and a good amount of boost then you should have a clamp or safc. you would be fine without wi if you run c16 or something close. i personally think most people should have a way to log timing and knock. so you might be able to get away with 110 or 107 if you have a way to look at those things. most people are paranoid over a couple of deg of timing. without any tuning and a 18spike i would get 29deg of timing on only 91oct. so most of my timing is from the wi not the safc. im sure when you are spraying if you use race gas you timing should be around 30deg. because of the cooling if the intake charge. so in closing i think most people if they are tuning there car already with a clamp or safc they shouldnt change what they are already doing. just change your fuel jet to get close to your street tune, but anytime you are spraying you should run race gas. or have a way to log knock retard and timing. it may take longer to get your car tuned crisp but i think most will be alot happier in the long run. btw sorry about spelling and puncuation in all my posts.
I'm not afraid of spraying the crap out of it:eveilgrin I just want to optimize my nitrous set up but keep things as simple as possible.:thumbsup:JollyGreen said:Dont be scared. Just spray and pray. I run a 150 shot of direct port. Granted i run a dedicated fuel line with a dedicated pump tank and fpr. But still....just go for it. Worst thing that happens is you blow it up. Then you go bigger and better the next time around.
