I'd venture to say the end result will impress, although I don't think the piping will be close to anyone's original assumptions.

Safest bet would be to find a dyno of the Kleemann supercharger on the M112 motor, and figure an additional ~10% due to the turbo being less restrictive. With boost, comes risk. Kleemann kept the PSI conservative for a reason...

I'll stay low and go with 275.2 with fingers crossed for more. Kleeman numbers were around 330hp /320tq at the crank if I remember. That should be good for ~270whp. As stated the turbo should be a bit better so around the 280whp range should be expected, time will tell. 270+ should be enough to keep me satisfied for quite some time though. I know it will never be a monster but this will give it enough pep to bring it out of the easy kill category and leave a few people scratching their heads.

Lol.. multiple small charge pipes.... to a couple.. to maybe only one a bit bigger.....

With Corky's expertise I figure it will be awesome however it turns out, but I agree.... probably nothing to do at all with how we thought it would be.

Exactly... and with the numbers they were producing (even with better heat shedding potential) we still wont hit 300 to the wheels..

But thats ok, we will still be at SRT level (or damn close). Throw a wavetrac in and it will be quick enough to not really care.. Im more excited about the balance factor of it being rear-mounted. Instead of the weight being added up front its actually just goint to get the distribution a tiny bit more equal.

I'd be shocked if the weight of the entire unit was more than 50 pounds... So I wouldn't look for a huge effect on the car's balance due to the weight. Now if you combined the rear turbo with a carbon hood, Shuriken battery, etc... then you might be looking at a 1% adjustment. Stock is 54/46 if I'm not mistaken, so you might be looking at a 53/47... Not a huge difference...

I've seen the stock SRT dyno between 275-285, depending on the dyno type. Factor in the 3.27 gearing and it should be an interesting race, as long as you're racing a stock one.

I'm most curious about the six speed, and how it's going to hold up. I recall the 1st gear being unbelievably short, even with ~245 flywheel horsepower. You guys with the 6MT and the turbo might as well launch in 2nd, hahaha... Not only for traction but for the sheer speed at which you will run out of gear and be forced to shift.

That first gear is incredibly short for sure! I run out of revs almost immediately. Problem I see is second is just a touch too tall for a good launch. Putting around town is fine but I can sure feel the slight bog when you get rolling in second. The turbo is going to take a part of a second or so to begin building boost so from a stop in second you are going to lose ground quickly.

Even a little difference like that can feel like alot in the right situation. I still havent tracked yet due to obligations but hopefully it will give me a little edge once I do. My seats alone shaved, on the conservative side, 60 lbs....

The 6 spd is what I am most worried about. Its also why Im not going to upgrade my clutch until I get real data on what the rest can handle.. Every time I do research I pull different results... Some people say its indestructable and some say its brittle as if made with toothpicks and buttons..... All I know for sure is that Im going to hate 1st alot with the turbo strapped on lol.

I remember Corky's solution to lag was shape and size of charge pipe. Bob and him were saying lag could be eliminated completely with small multiple charge pipes (small, to remain under pressure at all times), whether that pans out the way we were originally thinking or not, welllllllllll we will see. But as John and I were saying, the drawing board has been scrapped numerous times.

Yea 1-2 is always going to eat some time, first is to get you from the speaker to the drive through window to pay for your lunch. Even in parking lots you have to put it in second or look like an ahole screaming at 5k going 15. Like mopar said, second is just a tad too long for launch. With the extra power I don't know how long the tranny would hold out testing the theory either. The Daily driver will wait for others to play with that fire . Lantana may chime in with the V8 experience. I can't imagine first being more than a short pump of the gas once the turbo is on the 8 nevermind now. Just have to find the sweet spot I suppose, get on it smooth, shift a tad early and get into a real gear quickly. Third will remain the sweet spot i think, if your not pulling at that point it's probably not going to happen.

Goose it to boost it then drop the hammer from second.. sounds like a plan! LOL. I'm thinking you guys can forget first gear unless your out stump pulling for the day..

If and when these kits get installed I'm expecting a new set of threads on how to rebuild blown engines etc.
'How to install new pistons' etc.
'What is this part? I found it sticking out the crankcase.'
'Should I weld the crankcase or can I use crazy glue?'
'The repair costs more than the car's worth, is it worth repairing?'
'For Sale 2005 na with catastrophic engine damage.'
'New Turbo Charged stickers, free postage in the US , $5 to Canada'
'Lost on I-75, three con rods, three pistons and 8 qts of 10w 40.'
'Wanted cheap used Turbo kit, I want to make a gas turbine engine from it, contact me by PM, Turbomar.'

I'm just joking, but I am expecting new and interesting topics on repairs and maintenance of these beasts.

That is just ludicrous, everybody knows to use Superglue.
Now place your bet.

Oh you kids..
JB Weld.. haven't you learned anything yet.. Great for those blown thread connecting rod caps (just let set overnight) .. main bearing caps.. it's endless.. and you can thread it! Now the main topic of threads is probably going to be "wanted.. good used rear tires.. can't afford any more new ones!"... and in second place.. "how do I beat an excessive acceleration and speeding ticket"...

My bad, nearly forgot to jump in on the fun

I will say 285 +/- ~1 horse.

Assuming they've figured out how to dyno the car... otherwise,
