Hey all,

So I'm thinking about getting a supercharger come this spring/summer. Nothing too outlandish tho (450hp tops which should keep it hovering around 5k give or take... those are my ranges.)

I was thinking the Roush M90 application all the way. Rated at 435 hp & 400 tq (Part # 420023). They've really stood their ground, they're proven, reputable, and can't remember any major faults or complaints. The warranty is nice as well... LINK So is this a good buy?

There's also saleen, procharger, edlebrock, vortech, whipple, others?... Of which I don't know that much about- I've googled profusely ...... and gained a lil knowledge. But those with more experience with superchargers can maybe shed some more insights and info as to what the good buys are.

Also for install, I know everyplace is different, but what's that look like? 1-2k? I know my dealer can do roush, so i'm thinking to go there, or there's a few custom shops I've had work done before that I'd get a quote from them too.

Thanks!

 

The Roush M90 is way undersized for the 4.6. The Roush TVS on the other hand is excellent and is reasonably priced. If i were you I'd go that route.

 

Whipple makes an excellent supercharger. Their "low boost" kit is covered under warranty, but you should probably get that in writing.

I think Edelbrock's 2300R TVS kit comes with a powertrain warranty, too.

 

ehh... I don't need the 500-700+hp application tho

I like the whipple, don't get me wrong, but at $400 more, with 30 less hp than the M90 ... seems a bit off... $63/added hp

I really like the Edlebrock. The fit and finish looks great and 466hp and 439 tq is awesome. but it's a lil outta my price range at $6,500... and is only 31 more hp than the m90 and $1,500 more. $43 / added hp

M90 = $42 / added hp. end of the day, idk, I'm not willing to splurge 1500k on 30 extra ponies....

thanks for the ideas so far guys!

 

When you're comparing the dollar per hp make sure you take into account if the rating is at the crank or at the wheels. I believe I remember hearing the Roush is at the crank, but not positive about the others.

 

I am obviously biased about the Edelbrock, but given your mid-400 RWHP goal, this kit should not be overlooked. Not sure where you are getting the pricing, but the normal retail on the base kit is ~$5.8K and I have seen them on sale recently for $5K. But to put this into perspective, my base 5psi kit is putting down 422RWHP with everything else stock (fuel system and airbox) on a very conservative tune. Keep in mind that most of the bigger performance shops that carry them can give you a much better deal than advertised if you give them call... so definitely call around.

It is also realtively easy to install if want to save a few $$ as it took me about 13 hours with no help to get the task done. But should you decide to pay to have it installed, it should not be more than $800.

 

Check out Brenspeed if you're looking at the Edelbrock setup. Their installation is aslo very resonable; but then that depends on where you live. I'm doing the same research to help me get over the 5.0 itch.

 

I, like you, am on a budget and had modest goals for hp. I went with the Vortech V2 S-trim (non-intercooled). $3700 (parts) + $900 (labor) = $4600 total. I went from 240 rwhp stock to 364 rwhp with the blower (automatic transmission on a MustangDyno which reads lower than a DynoJet), for a total gain of 124 rwhp.

At the flywheel (like most blower companies advertise), that works out to 300 flywheel hp stock to about 455 flywheel hp with the blower, for a total gain of about 155 flywheel hp, which is less than $30 / added hp installed (or less than $24 / added hp if you can install it yourself). That's cheap hp for those of us on a budget!!!

More important than the dyno #'s are the timeslips at the track. I was looking for low 12's @ 110+ in the 1/4 mile and easily got there with a very conservative daily driver tune with a best of 12.14 @ 113+ mph in the 1/4 mile. A little more aggressive tuning & an intercooler would make my GT run 11's all day long.

American Muscle offers the V3 vortech kit.

http://www.americanmuscle.com/mustan...er-0708gt.html

With discount it comes out to 3,797.59

 

Yea after seeing the breenspeed site, I like the vortech V3 specs: 420hp & 385tq (fly). Price and install seem pretty decent, and from what Brian had said, these systems seem to hold up fairly well I'd assume? With little problems...

Consider this bad boy in the running!

discount code? I, sadly don't have the ins at american muscle...

 

the 420hp 385tq are actually rear wheel numbers for the vortech v3 lol, whereas that roush m90 will probably make somewhere in the mid-high 300s to the wheels i'd guess. I'm pretty sure that V3 kit from brenspeed is what i'll go with this summer..

 

I have the frpp polished supercharger installed by Brian oh five's dealership and it has been flawless for 10k miles now. Can you believe I already have 12k miles on #6333 Brian? Anyway, this kit puts down around 350 rwhp with oem drivability and 23 mpg highway with the 5 speed and 3.73 gears. I noticed you have an auto. Do you plan to swap out gears or do a high stall converter? If not, then the roots or twin screw chargers might give you a more enjoyable driving experience day in and out. It depends on what you plan for the car. If you like going to the dragstrip, the vortech chargers and their ilk are hard to beat. Not knocking the vortech, but you do need to rev it to get the most out of it.

 

No, actually the non-cooled V3 is rated by Vortech at 420hp/385tq at the flywheel. It's the intercooled V3 that'll get you over 400 rwhp (Vortech rates it at 460hp at the flywheel), but that costs an additional $1200-$1500 for the extra 40hp at the flywheel.

 

Phil is right about the centrifugals on an automatic car (like mine). To make the best of the centrifugals higher rpm powerband, you really should mod the car to get into the higher rpm's easier (like steeper rear end gears and/or stall converter). My shiftpoints are 6,400 rpm's, so I'm not revving the crud out of it, but the stall converter flashes at 4,800 rpm's which puts me right in the thick of the powerband instantly. No regrets with the V2 on my '07 GT. The car launches hard and really pulls at higher speeds, too. 0-100 mph for a stock GT automatic is about 13.9 seconds, and mine can do it in 9.9 seconds now. 4 second improvement in 0-100 mph is crazy for how little the V2 costs. Plus, I get 23+ mpg at 60 mph on cruise control (even with 4.10 gears and the big converter). Don't ask about city mileage, though, as I'm a lead foot and enjoy driving my car very hard.

Wow, Phil, 10K miles with the blower already? I know you have a long commute, but it seems like just a couple months ago when your blower went on. I, too, have 10K miles with my blower but it took 2 years to do it. I had a fluke problem with mine year ago (pulley bearing) that was covered for free by Vortech under warranty. Centrifugals are super reliable with Paxton, Vortech, etc. building them for decades.

 

I am a newbie to the world of supercharging, so please forgive my question if it is a stupid one.

What is the level of boost/HP/TQ at which the 4.6 would need new internals as well as other upgrades? Or would ANY boost require other upgrades? This tipping point would be important to those of us on a budget considering a supercharger. I searched but didn't find much discussion on this.

 

That can be very subjective as having a good dyno tune really makes all the difference as there are guys who run north of 500RWHP without issue. The general consensus is anything north of 475RWHP is a gamble.

 

I run a Saleen Supershaker which can be had now for under 5k. You will have a hole in your hood, but dam..Its a cool setup and makes good power. I am running now with a VERY conservitive tune @ 435rwhp. You can also get the Saleen package, (non supershaker) 475 @ a decent price from Brenspeed, or JDM. Depending on your shops, install can be anywhere from 800~1k.

I installed a M90 on my 06 Auto last year. The car runs smoother now than without the supercharger. It runs great cold, hot, summer or winter. Mileage dropped about 1.5 MPG both city and highway. The instant torque is incredible. I know it doesn't have the power of some of the other units, but it has more than enough for my needs (all street, DD). The only downside is there is no way to make big jumps in boost since it's a small unit (not a concern for me).

 

Are you sure? I know vortech lists their kit as that, but I thought he was referring to the Brenspeed V3 kit which from what I've seen usually comes in around those numbers to the wheels, on a manual and dynojet.

 

Under 5k? Where?
