I'm no expert on this subject but I would think the 24s would be good without the blower. With the blower I personally would get 30s or 36s, I bought the 30s and wish I had gone with the 36s.

I'd go with the 36#s. AT LEAST the 30#s. That's a pretty hot setup even without the blower.

Yup,your pushing the limits on your injectors right now.Installing a set of 30-36lb injectors I would be feeling alot safer if it was me..

Also what kind of fuel pump are you running?You should also have upgraded the fuel pump to handle this HP level also.

The guy at Dallas Mustang mentioned that I was at the limit for the 24lb injectors but he was able to add fuel to the new setting for the chip,before I put the car on the track I guess I can get it to a Dyno this spring?!?!?
It's not a daily driver so I will be easy on it. $$$$$$$$$$$ This thing is breaking the bank!!!!!!!!!!!!!!!!
