CobraMarty Posted August 23, 2014 Share Posted August 23, 2014 Stock crank pulley is 6 3/8" at the belt for figuring ratios. Love my Brown Dogs motor mounts. No movement and locates the engine perfectly. Gibson headers fit the Sprintex manifold, I used SS ceramic coating is best. Stock '98 style will fit, not '00+ with the dual pipes. All the little things really do add up $$. Link to comment Share on other sites More sharing options...
Alexia Posted August 23, 2014 Author Share Posted August 23, 2014 I picked up a deep jaw digital caliper and measured it across the top of the splines at exactly 6.5". Link to comment Share on other sites More sharing options...
89Patches Posted August 26, 2014 Share Posted August 26, 2014 I haven't been on here much, But this thing still ain't boosted? Also I wouldn't really worry about the the max speed of the supercharger, Because with the stroker of yours I highly doubt your going to keep making power pass 5K RPM's as the supercharger will probably be out of steam and the motor it self probably won't keep flowing past 5K RPM, plus it would be better to shift early to get back into your powerband.

Based on the data logging and information I calculated putting a 56mm pulley on the supercharger would settle it nicely in that lower power band. I plan on installing and tuning for the stock 58mm pulley first. I spend a bunch of time calculating before I do things since I prefer to figure out things on my own then just trust what I find on the internet. I was in the garage earlier measuring for what exhaust bends I need to order. Assuming all goes well I will be tearing it apart over the next month.

Alexia Posted August 27, 2014 Author Share Posted August 27, 2014 Built a bus bar from a door shim since the only post was crowded.(Cover not shown.) Cleaned up all the other wiring and fix some wire loom issues. An unfortunate meeting of many accessory wiring harnesses. The new headlight wiring harness, weatherproof relays, and connections. It is entirely built into the stock harness and is conservatively rated to handle 100 watts per bulb. Power routing over top of the fans. Low Beams - 55 watt - Impressively bright. High Beams - 60 watt - Everything is visible when driving with these on. Link to comment Share on other sites More sharing options...

I am very interested in how much boost the Sprintex makes with the 58mm pulley on a 4.6L stroker. A lot will depend on the head, valves, porting and cam. The Sprintex intake manifold will not be a restriction like a stock 4.0 intake. Link to comment Share on other sites More sharing options...

reece146 Posted August 31, 2014 Share Posted August 31, 2014 Secksi. Did you paint it or did it come that way? Link to comment Share on other sites More sharing options...
Alexia Posted August 31, 2014 Author Share Posted August 31, 2014 Secksi. Did you paint it or did it come that way? I painted it with Rust-Oleum Universal Red engine enamel. That is actually a replacement I picked up from the junk yard on Friday since I discovered the one I removed was rusting on the inside and clogging the injectors.

reece146 Posted August 31, 2014 Share Posted August 31, 2014 Yeah, I wasn't sure if you found a source for new/ fresh rails... that happened to be painted or whatever. Too bad no one makes these in stainless. Hmm... Link to comment Share on other sites More sharing options...

Alexia Posted October 6, 2014 Author Share Posted October 6, 2014 The exhaust still needs an intermediate pipe from the header past the transfer case. Now that the header is done I can work on that and finishing all the other little pieces. Header paint does a great job of hiding hideous welds. Fiberglass header wrap; only need on the first six inches or so to get the heat away from the intake manifold. Intake Manifold Installed Link to comment Share on other sites More sharing options...

Alexia Posted October 10, 2014 Author Share Posted October 10, 2014 New Belt and Tensioner Setup Supercharger Hung Linkages, Fuel Line, and Power Steering Feed Line - It all runs neatly between the intake manifold and supercharger. Getting creative with the vacuum ports and right angle brass fittings. A very nice 68mm throttle body from Painless Performance. Link to comment Share on other sites More sharing options...

CobraMarty Posted October 12, 2014 Share Posted October 12, 2014 A very nice 68mm throttle body from Painless Performance. The Painless 68mm TB looks very similiar to the F+B TB, might even be the same. The problem with them in this application is that they are too tall. You can cut the TB side of a 90* coupler shorter but it will still have a clearance issue. The 2 rings on the TB are not really necessary. You can cut off the upper ring and shorten the height of the TB to pick up some clearance. Could probably even cut off both rings and and shorten the TB height for even more clearance.

Alexia Posted October 12, 2014 Author Share Posted October 12, 2014 Is the manifold opening also 68mm? 66mm to 68mm in various spots. It is not a perfect circle. Link to comment Share on other sites More sharing options...
