The info that Jason from DOB provided is full of bullshit. There are 3 sources that rebuild Saleen series VI blowers. PSE superchargers in Edmund, OK. 281 Motorsports in Fullerton, CA. and Whipple superchargers also rebuilds them. The internals of the Saleen VI blowers are actually from the Lysholm 2300 twin screw S/C which the internal parts are still manufactured by Lysholm. Saleen performance parts also has a series VI rebuild kit in stock.

Wasn't referring to the DOB GT450 manifold. I was actually referring to the Eaton M122 blower itself that DOB includes as part of their GT450 kit. The point I was attempting to get across was the Eaton M122 which was also the OEM blower for the 2007-09 Shelby GT500 was around during the same time as the Saleen series VI S/C. Jason Etter from DOB gave the Saleen series VI S/C a favorable review on his website a few years ago, but has since recanted by claiming he has nothing good to say about them. Therefore, if the Saleen VI blowers are in fact getting impossible to rebuild as Jason claims? then the same could also be said for the Eaton M122 2.3 units as well. Also how is that DOB has so many Eaton M122 2.3 blowers in stock? Must be a good reason behind so many GT500 owners have sold/upgraded from their Eaton M122 blowers to either Whipple, TVS or Kenne Bell :shrug:

The 2007-2009 Shelby GT-500 folks have lot's of blower upgrade options to choose from, direct swap, perhaps a pulley change, and a new tune. Then they can at least get some money back on their M122's...so for them, it may well be a 'simple', cost effective upgrade.

So are parts for the Eaton M122 2.3 still being manufactured/available? If not, then how can they be rebuilt if replacement parts aren't available. At least there's 3 different sources to choose from that rebuild the Saleen series VI blowers that have replacement parts available. As mentioned previously, Saleen performance parts also carries the series VI rebuild kit in stock.

As a new guy, I don't know whether DOB ever posts here; they are vendors but haven't updated lately.

Here's an excerpt from Roush tech, answering my inquiry about availability of parts for their early S197 M90 kits: "We do not [sell those parts], I'm glad you inquired before purchasing as most don't. This is a very dated kit, we don't support but a few small parts and once those sell they're gone for good. You couldn't come close to putting a missing kit back together. We would suggest looking for a kit that uses the newer 2.3L Eaton head unit. It will make considerably more power, run cooler and be easier to service."

Again, my goal is to find a PD kit that will get me to ~450 hp / 430 torque and not break the bank. Starting from scratch, a DOB manifold kit leaves me needing S/C with intake plus the entire fuel and cooling systems, a tune, and other odds and ends. No doubt the DOB manifold is a wonderful piece, but it's a bit pricey for me. Not going to the track - ever.

All your responses are helpful. Also again, is there any reliable test for a used S/C that's not installed?

FYI, the M122 ran on the GT500 from 2007-2012 so there is 6 production years worth of OEM ones out there.

Instant boost with any PD blower setup....even at idle, at a red light, on my 2010 auto. Bam, instant tq hit. With an auto, it's good for a laff, esp with the oem 1.5 krpm tq converter. Tool around town at 30 mph in 4th gear, mash the gas, instant boost..and simultaneously the auto tranny drops down into 2nd gear..then hold on for the ride. 30-100 mph comes awfully damned quick.
I agree but be careful with the 4-2 WOT downshifts with the 5r55s trans. You will end up with a broken input shaft eventually

Yup, avoid 5-3, 5-2, 4-2, 3-1 shifts like the plague. The input shaft IS puny, at only 12 mm diam... = 0.472441". ( slightly < 1/2").

Do the hardened steel shafts from TCI help with this?

Yeah, instead of a bent or broken puny input shaft, the auto tranny grenades instead. I looked at JDM engineering' old notes, and they got one season (aprx 200 runs) on the dragstrip from a 5r55s. Then off for a total rebuild.

Thanks for the heads up, as I wasn't aware the Eaton M122's ran on the GT500 until 2012. I'm also just as baffled as Pentalab stated in his post below. Anyhow, if understand this correctly, was 2012 also the final year of production for the GT500 Eaton M122 blower or did it continue following it's run on the GT500 after 2012?

U are correct of course. 05-12. Baffles me, why they didn't switch to a TVS-2300 back in 2007.

I was also baffled as to why Ford didn't make the switch to the newer tech TVS-2300 that was first introduced back in 2006-07. I'm also at a loss for why they didn't select Whipple as the OEM blower for the 2007-12 GT500 :shrug:

The TVS blower wasn't released until 2009. The roush 540H was the first "production" car to have it.
Roush and Edelbrock were the first ones to bring it out in the aftermarket.

First impression on this forum was that the twin screw was far superior and that it was no better than a standard Eaton-that turned out to be false.

EDIT: Audi brought out one of the smaller units for the S4 starting in MY 2009 so it was before the roush 540H.

500hp factory built cars under $100K still were not the norm in 2007, so no good reason for ford to need anything more than the readily available M122.

And so the TVS 2300 blowers are no longer available for the 2005-10 4.6 3v cars either. So what other choices are still available other than Edlebrock, Whipple and Kenne Bell as far as PD blowers are concerned? Are there parts still being manufactured for the 2007-12 GT500 Eaton M122 blowers :shrug:

Ford would not use the whipple on the GT-500, since the whipple is not ISO-9000 / 9001. The roush 540 is interesting. That same engine was offered in other Roush cars. The deal between ford and roush at the time was the roush could not be rated more than the GT-500. The GT-500 was upped to 550 crank hp, so the roush was rated at 540 crank hp...which was a bit of a joke. Any Roush 540 consistently dyno'ed at 525 rwhp / 596 crank hp. The roush 540 used 8.5:1 CR....and the TVS-2300 was run at 14.7 psi boost. With just a tune, VMP saw big gains on a Roush 540.... until u got to the top end. That is where the curves converged. It runs out of air at the top end, with the oem stock 2010 airbox. The fix for that of course was the giant open cone filter. Once LT's and a bigger TB were added to the mix, it just kept on increasing in rwhp.

On Roush's 575/625/650 kits, (11+ cars), they swap to the cone filter on the last one. The 11+ oem airbox flows less than the 2010 airbox. The 05-09 oem airbox's flow the lowest. I ended up installing a K+N filter in the oem box on my 2010. You can hear it scream through. Replacing the oem upper grille on a 2010-11-12, with the 7 bar upper grille does wonders. The oem upper grille is 80% blocked off. The 7 bar upper grille allows a lot more air into the upper grille. It also eliminates the 2 x 90 deg bends into the 'snorkel', that feeds the oem airbox. Boost increases by aprx .4 to .5 psi on the hwy. The Roush HE on the 2010 M90 is identical to the 2010 TVS-2300 HE, both are 18" tall x 21" wide. The HE is at the very front..and gets hit with air from both upper and lower grille. With the 7 bar upper grille installed, you can now see the 'snorkel' at extreme right side (driver's side), through the 7 bar grille. 7 bar grille install also means an upper oem fog lamp delete.

Where is DOB getting all these used 2007-2009 GT-500 M122 blower's from ? Is there that many 07-09 GT-500's that have had their blower's swapped to whipples, tvs, etc ? M122 is a 122 cubic inch displacement blower. 1 litre = 61 ci. The M122 is a 2.0 litre displacement blower...which is a good size for a 4.6 L eng.

Apparently, he has sources. I just happened across a low mileage (3K) one for $300 w/TB that someone had upgraded (like most of them) and for my purposes it's been fine. Of course I'd like to upgrade to a TVS but $3K or more isn't in the budget right now and of course I'd need to also build the engine which really means $8 - 10K. Not happening right now.....

So where you coming up with 3K or more for TVS 2300 blowers? Both Roush and VMP discontinued production years ago for the 2005-10 cars. Can't even find any on American Muscle, Late Model Restoration, Summit Racing or CJ Pony Parts. And I sure in the hell won't pay 3K for a used one, including from DOB.

Speaking strictly from; if memory serves me that is... ebay but quite a while back. Could have been looking at a different model... Jason did have some used 2300's around $2K late Sep last year but said he would only accept M122's if one wanted to save a little in trade. Said they would bolt up to a GT450 manifold.
Thanks for the fact check. Will do a better job on details in the future. :hail:

He's talking about $300.00 for a used M122 blower...from a 07-12 GT-500. apples and oranges.

Read the above quotes once again. He was specifically referring to used TVS 2300 blowers costing between 2K-3K. apples to apples.
