Should I stick with the 4” pulley or do I need to go with a 3.90 or 3.80?? Anyone run a similar set up or have a rough idea of what to expect?

correction: I’m running 91 pump gas with the dual nozzle water/meth kit
the injectors are from my previous setup with the D1SC was hoping I wouldn’t have to upgrade just yet I have NO IDEA why I didn’t order the ID1000. Dumb move on my part they cost the same as the 725’s

I should be within the 16-20psi range. Same thing Procharger said when I called them a while ago to double check/inquire about the clamps that came with the 4” front mount kit.

I've seen idiots squash stainless steel tubing from overtightening t-bolt clamps. You can just get idiots everywhere that can **** things up.
But for low boost stuff there is simply no need for t-bolt clamps. And some t-bolts are pure ***** to start with.
Once into larger diameter like the 4" a t-bolt can become more appropriate simply due to the forces involved but as long as pipe prep is good with a decent lip/bead, a good worm drive will still be fine ( I use Breeze constant torque clamps )
91 octane might be a stretch, also the 60E might not be happy. I favor T bolt clamps,
have had the worm style slip. Most important is a lip of some sort around each pipe
so it cant pull out. I wish my garage floor (or my kitchen, lol) was as clean as your garage.

A lot of people still hate on the 4l60e but if it’s built right, kept cool it will definitely withstand. RPM has has gotten a few 4l60e into consistent high 8 low 9s. I’m not too worried about it. I’ve added a few precautions such as ATI Flexplate and larger tanny cooler with a deep aluminum pan & proper gauge set up to monitor heat it should do great with the upgraded 1: 2 gear ratios.

tranny is billet and hardened where it needs to be, it’s an RPM build...the junkyard 80e w/ shift kit is on standby but we should be ok haha. I’ll be on the lookout for that stage 25 though lol
