[QUOTE="tt335ci03cobra, post: 12536574, member: 68944"] This build is awesome and has me excited to finish mine. You've made great power and are running times faster than I expected to run at those power levels. 8's will be within reach for ya with just 1-2psi more and new tires for sure. I think I can do better than I hoped based on your awesome results so far. I have an IRS though but it's built and runs 1.50's cake, might crack 1.45's on brand new slicks/skinnies. I like the idea of the eaten for low end especially on a huge single, good choice. I'm just running simple twins but even with a Sullivan intake my power is more than great. Lag is only an issue below 2800rpms in 3rd-6th and barely at that. Mines too torquy so we've got a 3.08 rear and run 28" tires. It makes 920tq at 4300rpms on 18psi which just spins under 100. I made 885whp on 18psi with just twin 57's on my 9.2/1 modular but the waste gates were wide open (48mm hot side). Seeing you make similar power and hit 9.30's has me giddy to get to the track next summer. We're putting 61/60's on this winter with a custom 3-3.25" turbo back setup. Should be in the 8's with traction while keeping good torque. I'll be with a smooth 1050whp on 28psi from 5400-6500rpms but my tuner says itll make 1100+ pretty easy that high, hoping. I haven't had any lag issues with the 57's, I bet the 61's will feel pretty good too. The better a/r and hotside going from a 48 to a 60 is what will up the power dramatically from what I was told. Right now the 57's fully spool 18psi by 3600rpms so I'm guessing the 62's will fully spool 28psi by 5000, that said though it won't feel laggy because it'll easily make 12psi by 3000rpms which should make 700wtq easily even that low in the rev band. Wheeeeel spiiin haha Good luck on your build and I'm gonna subscribe, can't wait to see your rig cross 8's with a stick and full interior, that will be so badass man. Congrats. Based on these specs, do you think i can sneak into the 8's as well with the 61/60's? cheers.
