Thanks, but my wisdom springs from http://www.tempotopaz.com, an outstanding source of info. I know this whole project sounds crazy, but I've always wanted to do something different. The feedback I got at the tracks was very encouraging; most of the racers & others at the track got a kick out of it!

Here's a little update on the bracket I need to hang this monster. The 'ears' on the mounting plate towards the back of the motor used to mount the M62. I kept that part of the bracket intact, so that if this doesn't work for whatever reason, I can simply reinstall the M62 and roll. I'm going to use the holes as attachment points for the rear half of the new bracket. The bracket will bolt together, with its rear half also attached to the block at 2 points. The supercharger will then bolt to it. The mounting ear near the oil filter adapter will be a bit close; I'll have to do some slick bending to make it clear, but I have the room to get it done. http://img246.imageshack.us/img246/205/blowerfrombacksidewp9.jpg http://img246.imageshack.us/img246/4454/wiiiideloadhf8.jpg Here's a size comparison between the M90 and the M62. Note that the M62 still has its intake plenum attached, making it look larger than it is. I'll have to make all new intake/discharge hardware, so I can keep the old stuff in case I need to use the old blower. http://img175.imageshack.us/img175/5292/sizecomparison1oh6.jpg

Awesome pumps, just louder than stock. With a good dose of blower whine, I won't hear it!

That left a mark! Oldie but a goodie

MY EYES! MY EYES! They BURN!!!

I love the B-body Impalas; an LS2+M6 swap would be sex. As for the Catera, I've heard they lack reliability, and the styling is weak.

Clean machine, looks good. I'd rock it! The wheels aren't my favorites, but they suit the styling of the truck. Should serve you well.

Do my future plans seem unrealistic? Nothing is definite, and my output figures are probably a bit optimistic; fueled, perhaps, by the car's profound response to low boost. I'm bound to hit a wall somewhere; be it flow related, like an element of head or port design, or structural, as in reaching a point where the block or crank just won't take it anymore. I hope to finish this stage of the build, get a good year or so of running out of it as a daily driver, and upon tearing it down, gain real-world info on the engine's weaknesses. If it fails, I'll still learn a shitload, perhaps that will reduce the chance of failure when the boost (and the money invested) goes way up. I could see a forged motor costing twice as much or more than stock; I priced custom-made pistons at roughly $100 each, and having rods made will bump the price up considerably. Then comes the machine work...

Not much to know engine-wise; internally, the 2.3 HSC is basically an old inline "6" minus 2 cylinders. It was used only in the Tempo/Topaz, though a 2.5 liter version was used in the early Taurus/Sable. Though often confused (even by Summit!) with the 2.3 OHC motor, it shares nothing but the displacement. Bore, stroke, everything is different. One of the members at tempotopaz.com may have worked out some forged parts from other apps that might work. Boring the engine out may allow the use of 305 Chevy pistons, certain rods that may adapt, etc. Don't know about a metal head gasket, I'll have to look that up. Supposedly, there's a company that will make them to fit anything, but the cost may be high. It will be needed when I start cranking up the pressure, though. I'm doing this thing in 3 stages; stage 1 was the previous setup. Making everything fit & work together, just seeing how the engine would respond to low boost. It responded quite well; according to an online HP/ET calclator, my stock wheel hp was 83. That's right in the ballpark for a stock sewing machine with 140k on the clock. After boosting the same tired motor, whp was calculated at 133. Both were based on the same 2700# weight. I know those 'calculators' are nothing but guesstimates, but still pretty encouraging. It took the car from a stock 18.7 to 15.9, with shitty narrow tires and a stock fuel pump that was choking at the top end. Traction and better fuel delivery would have made a difference; trying to guess how much would be pointless, but I knew the car had more in it, even then. Stage two; Fresh motor, bumping up the boost, header & custom exhaust, Walbro pump, etc. Target HP in the 200 range. I'll need to make a dogbone for the engine, and fill the mounts with urethane; otherwise, I'll trash them in a hurry. The mounts on these cars are craptastic. Stage 3; Forged motor, boost in the mid/high teens, rockers & headwork, anything else that comes to mind. Target HP; 300. Lofty goals, I know, and reality may force some adjustments, we'll have to see. Any opinions on the future plans?

ROFLMAO!

Thanks, guys! EDIT; ...and Merry Christmas!

Sweet! Thank you!

Some clothes, a few tools, and my sister-in-law had 'team' shirts made with our names on 'em. Kinda cool, really. Now I GOTTA get the damn car done (and running well); hard to look cool when you're standing in the staging lanes without a car..,

He will be missed. Oh, yes. That man put out more energy in 5 minutes onstage than most people do their whole lives!

Cool! Owning you would be a pleasure! Should I bring one of the GTPs, or the Tempo (pending completion)?

As far as I know, they probably will. It stood up to a whole summer of outright abuse, on a high-mileage motor at 6.5 psi, and when I pulled it down, it looked pretty good. Only damage was caused by my own stupidity; I jumped on it in cold weather without the boost retard dialed in, and broke the first ring land on 2 pistons. Between the loud exhaust & the blower whine, I didn't hear the detonation until it was too late. Yea, I was a dumbass, but I won't do THAT again lol. I guess I'll find out in '07. My GTP has a hitch; I'm buying a towbar for the Tempo. It'll be driven everywhere it goes, but if I break something, I can drag it home without paying through the nose. I'll attach the towbar brackets behind the bumper, so if I kill it, I can slide the bumper off, pull the bar out of the trunk, hook it up, & go. To go higher boost-wise, I'll need forged pistons (none available, likely cu$tom-made), forged rods (hope I can find existing ones that'll work with a resize, otherwise cu$tom). No forged crank exists, so I'll have to go with main studs & fab a girdle when I go for the 300 hp mark. I already have head studs from ARP..no kit was available, but after I took some measurements, they found existing ones that fit perfectly. I hope they can hook me up when I need the mains.

Well, for whoever gives a fuck, here's what I'm thrashing on this winter. I was in the midst of rebuilding the engine in my s/c'd Tempo, and decided to upgrade to a larger blower. This is a mockup of my previous setup. 6.5 psi, dropped my et by 2.8 sec. It worked very well; aside from the occasional 'check engine' light (thanks EECIV), it was daily driveable, and a real ball to romp on. http://img204.imageshack.us/img204/3109/picture042vz2.jpg http://img100.imageshack.us/img100/9691/picture009yv5.jpg Now, here's the new plan; it's gonna take some work, but after last year's results, I'm up for it! The front part of it is mounted, I'm laying out the rear support now. I'll have to build new intake & discharge ducts, move the rad to make some room, etc. I'm hoping to run 10 psi, but I'll have to see what I have when it's done, then adjust accordingly by swapping pulleys. http://img204.imageshack.us/img204/4971/hscwm901nn3.jpg Here's a shot of the header. The 2.5" exhaust is made, but I can't fab a downpipe until the engine is in the car. http://img100.imageshack.us/img100/6986/hscwheader1bp2.jpg Opinions? Tips? Waddaya think?

SWEET! The perfect addition to any sleeper!

Here's one for the 'old-schoolers' in the crowd.., http://img299.imageshack.us/img299/5563/1972hurstoldsvistacruiskw7.jpg

I got a chuckle out of that myself...sorry Putty! :zoom:

"Disc brakes" look fake; where are the calipers?

Congratulations, man!

Well done, but not my style...

Where's that :werd: smiley? I'm in the towing & recovery biz...that snow is 'white gold' to me!

Perfect ass...absolutely flawless.
