Re: I should not be left unsupervised
Pocket, why not build a simple blower intake manifold for it? it seems like you have the skill to do a nice intercooled setup.

Re: I should not be left unsupervised
Cheap ebay intercoolers stand in the way. Maybe he could apply a cheap ebay FMIC to make a liquid to air.

Re: I should not be left unsupervised
I braved the cold for a little while. Whatever happened to global warming? 28* with a 20mph wind... BRRRR. I wouldnt bitch too much except this is NC, not Wisconsin
Anyways
Rough fitment with the finished plate. Outlet hat isnt going to be as easy this time

First two bolts may need to be welded to the plate before building the hat if I keep the modular design

The inlet opening actually has the same perimeter as 4" tubing. Good news so I can simply squish a 4" tube and weld it onto the flange. No reducing or similar to create turbulence (noise) before the rotors

Thinking instead to weld the main bracket to the blower plate and cut a hole in it for the charge pipe, then form the hat accordingly. It would kill the modular design, favoring one large assembly the blower bolts to then bolts the whole thing to the head. Im not sure how easy the bracket to head bolts will be to access once the tensioner is put on

The downside of one large bracket assembly is the belt alignment becomes critical at the beginning of the fab and warping becomes a major issue. With the modular tray/plate design, slight errors can be addressed by redrilling a few holes and shifting the blower to suit
First of the 3 crank hub pieces came back. Looks sweet. Said it'd be about 3 weeks before the others are done

Re: I should not be left unsupervised
New heater core, painted the new heater lines black and installed with fresh hose. Flushed the coolant system, added a pillar pod to hold my boost/fuel press gauges. Pulled the dash hunting the vacuum leak to why the heater door wasnt moving. Took some measures of the current plates and modeled them in CAD. Used those models along with a few accessory drawings to build final assembly drawing
Tensioner is my biggest hurdle. It has to be located in space on the upper side to clear the WP pulley. Problem is it rotates counter-clockwise. Id switch it for a clockwise rotating tensioner except HD units made for a blower dont pop up FS very frequently and new they are about $150 each. Ill make it work anyhow
Its bolted to a 1" tube thats welded to the main cyl head plate. Support rods to the blower tray and waterpump. Hopefully it wont move much. I do miss having Solidworks to test it out though

10 rib belt, 216* of belt wrap on the SC pulley and 205* of wrap on the crank. It better not slip... ever
Crank pulley is 7.8" dia, SC 2.6". Drive ratio is 3.0, so the blower should be spinning about 19,500RPMs when I hit redline. Screamin'![nod](https://www.thirdgen.org/forums/images/smilies/nod.gif)
Once I get another engine to play with Ill start mocking up the headers. Modifying a set of NASCAR SB2.2 headers, 1 3/4 stepped to 1 7/8 primaries, stainless. I hate to hack them up, but I cant seem to sell them

Re: I should not be left unsupervised
WRT to belt wrap, have you ever seen what KB does with their blowers, like the mustang kit has a heavy plate that mounts on the front of the block (relocates the alternator so it's spun around) with 2 adjustable eccentric pulleys on either side of the belt pinching it together just below the blower pulley

Re: I should not be left unsupervised
Actually, here is one that I did a while ago that you can kind of see what they did:

Stillen does the same thing with their 350Z/G35 setup (also eaton based, M90....), but they also use a small jack-shaft that installs in the front wall of the block.

Re: I should not be left unsupervised
I went picture hunting and didnt scroll up. My bad
Was playing with the pulley locations trying to make a design that cleared everything. Between the charge pipe, accy drive tensioner pulley, waterneck, and waterpump pulley, it was pretty tight
Two fails out of about 20

I moved the plate to the front which allowed the tensioner to be reversed. This helped two ways, the HD tensioner body doesnt interfere with anything and the pair of pulleys can overlap planes without physically touching

I dont see how to add one more idler near the SC pulley to maximize wrap without adding a second down low to prevent belt to belt contact. The lower I go, the less there is to bolt something to. Might just keep things simple with the 3 point belt. I checked the length VS Goodyear's belt catalog and Im still well within common belt sizes

Re: I should not be left unsupervised
I sure wish I could swap my vortech for a twin screw, too bad it aint worth **** anymore compared to the prices of a twin screw.
I think a 177 would annoy me just knowing how inefficient it is.

Meh, centrifugal is the way to go on a street car, hell, most race cars nowadays seem to go to the centrifugal as well.

This should still take a stock LS1 crank bolt and be able to be pinned just like a normal balancer. Ive read horror stories of people spinning pulleys with a 6 rib. I *know* the 10 rib will spin if not attended to
Trying to line up a LQ4 next... it never ends

Re: I should not be left unsupervised
Got another motor to tinker with
Cheap engine stands are difficult to get perfectly level but I got it. Must have switched the camera to blurry mode though

Another 50,000 mile LM7
Perfect for cheap boost. Buy my Firebird, it comes with a blown LSx already installed

Re: I should not be left unsupervised
That si why i am turbo charging a 08 5.3, if i destroy it by throwing too much, i just go spend a little bit on a new short or long block.

Re: I should not be left unsupervised
So how much can you anticipate to gain with this blower over the other one, without touching anything else?

Re: I should not be left unsupervised
The problem is Im changing everything. Only similar part is the fact its a mostly stock 5.3
4L60E to 4L80E
LS1 cam to LS6 cam
Manifolds and Y-pipe to LT headers and duals
36 to 60lb injectors
Single walbro 255 intank to dual
Returnless to boost referenced return style fuel system
2.73 open 10 bolt to 3.73 posi 8.8
Atleast thats the plan. And just for numbers sake, Id love to hit the magic 500 but like the last endeavor, we shall see

Re: I should not be left unsupervised
Torque is the fun part
Worked on the outlet collector today and nearly finished but hit a snag. My plate warped really badly. Ill have to cut the front loose and attempt to bend it back. Never seen 1/4" plate warp that badly and Ive put some heat to them. First time for everything though, May be fixable, may have to start over, Ill find out tomorrow
I thought out how the assembly would go before I started fabbing this time and it went smoother. I used geometric shapes as a beginning with simple cardboard filler sections. Took about 4 hours to get this far as opposed to the 2 days for the previous. Im also getting better at welding wierd angles and tight locations so I should have alot less leaks to track down
