Would like to share my experience with the "hammer" kit. But first a shout out to Ken from Magnuson, everyone at XLR8 performance, Jerry from Eurocharge and Brian from Dynotech Tuning. These people made it happen for me.
Brought my car down to the XLR8 in CT for the install about a month ago.
I bought the tuner kit from magnuson, since my car was not stock. On top of the supercharger, I also upgraded my injectors, as recommended by them, and bought a smaller pulley from them for whenever i wanted more power.
The installation was pretty straight forward, the same however cannot be said with the tune. Since it was a tuner kit, it didn't come with a tune, and we reached out to Eurocharged to see if they could do a tune, since i had a v5 tune from them. XLR8's dyno was down for the time period my car was there (couldn't get pre-install pulls), and Jerry did not have experience tuning the kit, so it made our lives pretty hard.Took about a week of loading tunes and test driving, before eventually got to the point where the car was drive able. But most of that time in the shop was because they could not test drive the car due to snow. To clarify though, OE tuning are the ones who created the tune for the standard kit, and will most likely not experience the same problems or at least to the degree of problems I had.
Anyways, I eventually took the car home about 2 weeks ago, and by no means was the car running great, but it is my daily driver and living without a car is hell. The car ran okay, albeit a bit rough. Did have issues with the car, but not going to dive too deep into that. A week past by, and I was able to head down to Dynotech last Thursday for my first dyno session to do remote tuning with Jerry. They have a mustang dyno and the car put down 467 Hp and 429 Tq on the last tune file of the day.
Was happy with the numbers, but wanted a bit more, so switched to the smaller pulley a few days ago and went back onto the dyno today. The standard pulley (70mm i think) made about 5.5psi and the smaller one (65mm) made 7.5. Final numbers of the day came out to 497 Hp and 433 Tq. For reference, someone's bone stock c63 pulled 317 Hp and 310 on that dyno. I know conditions and cars are different, but assuming 451Hp/316Whp * 497 Whp, 443/310 * 433 ), my car puts down 710 Hp and give or take 630 Tq at crank. Needless to say, I am very very happy. Car runs very smooth now, but will still be looking out for problems.
Interesting fact for those who own a valvetronic exhaust like mine or is considering buying one. We did a pull with the valves opened vs closed, and difference came out to be about 30WHp. Obviously the difference will not be as significant for those who just have the catbacks or headers, but still a difference nonetheless. That about wraps it up.
Attached some pics of car and dyno graphs.
Here's a video of the car on the dyno. https://vimeo.com/155714204
That's stupid they sell this kit without a tune for headers. How many guys want to drop 10k on a blower and dont already have headers, doubt very many. I know of one guy that has a stage 1 Weistec blower out of a handful.
Seems like a lot of pissing around to get a half *** tune. Running lean off the go and doesn't richen up that much. 13-14 AFR with boost on a high compression engine seems kind of lean to me. Id like to get around 12-12.5. I think Weistec runs 11.9 with the stage 3, not sure what they run with stage 2.
For the price of the blower and then you need tuning, you probably come out costing more than a Weistec stage 2 kit?
Looks like decent numbers out of 7.5lbs of boost, what correction factor was that done in?

Curious to see some drag strip times.
There were a couple of cars out drag racing last night not sure what times they were running but I did hear 1 ran 11.3 not sure of there mph but I also heard another cR ran like a 13.7 but he was on street tyres

Well i ended up about spending the same Weistec's stage 2, but this kit is definitely cheaper than the stage 2. The blower itself was 9,500 (I got 500 off being the first few to purchase the kit.) The injectors, injector adapters and fuel rail came out to be a bit less than 1500, which i don't think stage 2 includes. Assuming installation is 2k for both, its 13k ( blower + install + tune (oe quotes about 1k)) for magnuson vs 15k for weistec.
Not sure about correction factor can find out tomorrow.

Gotta agree with Merc63, I wouldn't want those AFR's on boost without race gas. It fattens up towards the top end which is good, but would rather see closer to 13 in the mid range if not under.
Glad to hear a review on one of these in the wild though, good work. Will be interested to see some 1/4 mile times when the weather gets nicer.
Would like to share my experience with the "hammer" kit. But first a shout out to Ken from Magnuson, everyone at XLR8 performance, Jerry from Eurocharge and Brain from Dynotech Tuning.
Thanks for the "thumbs up". Not the smoothest of solutions when trying to work with different calibrations etc, but we got there. It was very cool how all parties were willing to work together for the good result.

It is not possible to sell a CARB-compliant calibration with headers unless they are specified headers included in the kit ... which defeats the purpose if the car already has headers. Those are the CARB rules.
There are no AMG kits sold with headers that are CARB approved. If we sell a kit with a tune that is not CARB compliant, the fines are horrendous.
However; we do offer a solution that is a non-CARB-compliant "Tuner" kit & then the onus is on the installer &/or owner to determine compliance. In most cases, the tune needs to be "custom" as not all headers are equal, some cars have cats deleted, some have full systems, some have ROW air-boxes etc.
And of course everyone has their favourite tuner, & only wants that person/company to tune their car as they have already done the tweaks for that car, so supplying a tune seems moot.

We did have a couple of cars out last night, both were on street tyres.
My car was full weight (including spare wheel, full tank of fuel, & overweight driver ).
My rears are PS AS3's (275/30/19). First time on the track in 25 years, and I could not get traction. Failed terribly on the first run; 11.56 @ 129.6 on 2nd run; and then ran 11.37 @ 129.9 on the final pass. With practice I speculate an 11.1 would be my best on streets, sub-11 with slicks.

Why can't you sell with a tune for race or off highway purposes and end user takes the risk running on the road. To my understanding, this is how everyone else sells aftermarket stuff?
I second the opinion on the valves exhaust....closed position...lost over 30hp compared to open...dyno tested..glad your car is now working. Kit looks real clean.

Because of very strict government regulations in OZ. Not sure if it applies to international sales though.

Because they have cracked down on this - hard.
If sold as a kit, the onus is on the manufacturer. If sold as components that do not enable the purchaser to operate the product without purchasing "a significant portion" elsewhere, the onus is on the owner/installer.
There was a 7-figure fine enforced on a Californian exhaust manufacturer a couple of years ago.
Small companies may be less likely to be targeted - Magnuson will not risk it.
Nice numbers overall however, don't folks put down 450-470 rwhp with LTs and a tune depending on dyno?
That being said with blower and smaller pulley you only gain 50 rwhp?
The numbers you are referencing are from a dyno jet. My car was on a mustang (chassis) dyno which always reads lower than the dynojet. How much lower really depends on the machine, some say 12%/15%/20%, which is why i included the numbers of a stock car to estimate the numbers at crank. A stock car on a dyno jet reads around 370 but it reads only 317 on this dyno, so you see how much of a difference that is. Giving you another point of reference, Jerry had another customer that got reading on a mustang for 470 and 562 on a dynojet.
Considering all that, car probably puts down something in the neighbourhood of 600wheel on a dynoject, so comparing to say a 470wheel car with tune + headers, it more like 130whp gain.

Your story cannot adding up, LT's have never been legal or emmisions compliant yet tunes are selling turn key kits with tunes. Also, those AFR's are nowhere near safe, that motor is not long for this world.

Lot of people have already mentioned the AFR is potentially an issue. I know someone already mentioned ideally it should be 12-12.5. I personally don't know much about that, what would be the ideal ratio for what rpm?? Will definitely be in contact with Jerry.
