Second build up from the short block

Did you have belt slip with a similar setup?

Been doing the supercharger thing on these Gen 1’s for over 20 years and from experience I know that once you go below a 3.15” upper it starts getting harder and harder to keep the belt from slipping.

You can tighten the belt more and more and more to try to overcome that but at some point guys have to start worrying about what all that tension is doing to the bearings in the supercharger and the main bearing on the front cap of the engine.

That’s why a bunch of us started using a water pump and timing cover from a SN95 Mustang and having a custom water pump pulley made so we can use a larger crank pulley.

Sunday at Spookfest we were seeing 15#’s of intercooled boost on Tommy’s 357 with his Si-trim with a 3.60” upper and 17#’s with a 3.33” upper. And that’s with not a ton of belt tension.

Got ya man. I figure I might as well try it then go bigger as needed. Guess we all learn by trial and error lol. I appreciate the feedback though for sure.
 
I have been looking at the big brushless pumps by aeromotive and fuel lab. Definitely pricey. I just wonder how they will do on the street. I got 800lph worth of pump now and I'm almost out of pump as it is.

For me it’s the ability to give what is needed vs cycling maximum volume at idle or cruising. Large volume pumps can cycle through and warm up the entire tank in minutes.

Not sure about Holley, but Megasquirt also offers open and closed loop PWM control of the fuel pump. Never used it though.

Think it causes interference with the tps reading. However imo it's the perfect spot.

I’m sharing my TPS with the quick 4, as long as the two systems share a common ground(sensor ground) there’s no issues
 
I took my rear differential housing to a local shop to get the gears set up. I do most things myself but It’s not my favorite thing to do. While it was out I pulled the gas tank and made some adjustments.
I made the sump myself in 2016 and put relief in the top of the sump so the gas could drain to the sump but it wasn’t low enough after welding it together so I recently fixed it to maximize fuel circulation, cleaned it extensively, added a bigger vent, and re-installed it. Ordered parts to install a large vent with roll over protection valve.

I picked up the rear differential housing and installed it. The wheel studs were hitting the brake spring so I ground each one off slightly to clear it.

I didn’t notice it when I had it in the truck for mock up but I’m having a clearance issue with the “street bracing” and the frame. This picture is after I shortened the tabs by an inch.

I didn’t really like the looks or the routing of the stock emergency brake cables, so I ordered a universal kit from Wilwood and I’m happy with how it turned out.

Looks good man. I actually eliminated the parking brake on both my trucks. I have the parts to reinstall it on the 95 but I haven’t yet.
 
I'm about to service rear drums on our generation of truck for the first time. Wow, what a big difference from the later generations.

We have to have a p-brake here to pass inspections.
 
I almost wrapped up the rear differential install. I ordered a stainless drain plug, when it comes in I can fill it with oil. Ordered a hose barb to install the breather tube. Only thing left after that is to install brake lines and bleed the brakes. The shock mounts are blocking the path of the original brake lines so I think I’m going to use flexible brake lines, not sure yet.

Once I order and install the driveshaft all the major components, besides exhaust, will be done. It’ll be down to brake lines, wiring, fuel system, engine accessories, and putting the front end back together.
This has taken much longer than I want but once it’s done I should be set to enjoy it for a while!
