Upgrade to bigger shot? I got my car dyno'd the other day. After tuneing with LS1edit my best was 337 RWHP. Then for fun I did one nitrous pass with my 100 jets after that. NOS 5177 dry kit. I had over 900 PSI. I only made 394 RWHP. So I was a little disapointed in only getting 57 RWHP from a 100 shot. I was thinking about going with the 125 shot for my trip to the track this weekend. I'm just wondering if I'll still be safe running that large of shot engine wise, and I'll be making over 400 RWHP so will my fuel system be able to handle it? Any input on the dyno #'s would be appreciated too.

Re: Upgrade to bigger shot? I pulled 324/335 with lid and catback. With .040 jets in my 5177 I pulled 429/512. Had a lean bump in the A/F, so it was a little much for the stock MAF on the initial hit. Just ATAP it and watch it like a hawk with anything over .036 jets <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

You need around 1100 PSI to get your advertisted HP rating from dry kits. I would not trust anything higher then a 100 DRY shot on a stock fuel system. Either go with a wet kit or upgrade the fuel system...ie..bigger pump - bigger injectors...
