Hi all, I am selling my used BBK 65MM throttle body and my ported stock inlet elbow both from my 2010 GT500 still running the stock M122 Eaton. The BBK TB does come complete with the FoMoCo electronics, I believe these come "bare" without the electronics when new. I am asking $250 for the...

The rear springs have “Steeda FD023 RSA” written on one set of coils and the fronts have “FD022 FSA” written.

$125 now. Any takers?

Hi all, I am posting my used GT500 Steeda lowering springs for sale. I changed these out for an Eibach set on my 2010 GT500 and ended up keeping the Eibach set. I think these are the Sport springs if I recall correctly and provide something like 1" of drop in the front and 1.25" in the rear. I...

OK, but is that still the case if the 67 and the 69 are the exact same price? That is my dilemma, I may also some day upgrade the blower but am not certain.

Yeah maybe, but there appear to be a ton of folks that run the 67mm with closer to 800 wheel, more so than those who find it to be a restriction at 700 wheel. I have seen several folks quote flow tests that indicate the VMP being within only 50cfm to some of the monoblades. That's pretty darn...

Yeah...that is also correct. My point is that the VMP67MM is within a very close margin in cfm potential to the larger monoblades, which is impressive. A rep at VMP made 1088whp with a 67mm but explained that in the context of my application the 69mm is meant to be for guys who dont want to run...

Yeah, I hear ya! Unfortunately, I don’t live near my old tuner anymore so I haven’t been able to visit but I also haven’t called to ask. The general consensus seems to be that monoblades are slightly harder to tune but when done right are great, otherwise run the VMP or similar 67mm throttle...

Ok, so, I talked with VMP on the phone today and the 69mm throttle body will fit with their VMP high flow inlet elbow but not the stock elbow. Just putting that out there for others even if I may go with the 67mm. The 67 will support close to 800whp and the 69 is really meant for those that...

Going to call VMP tomorrow and see if I can get a good answer on the 69mm throttle body, but we'll see. Its important to note that the VMP inlet design on their TBs seems to be superior to the CJ65 so its about more than just the extra 2mm. Looks like the flow characteristics and cfm flowed...

Yeah, I'll tell you guys what, I am usually very conservative with HP gains as I think most people are. However, this is another example from BJ (VNMOUS1) where he describes going from a stock TB to a CJ65 and then to a VMP 67 with no other changes. Car was a 2007 GT500 but I'm not sure what the...

Thanks for the reply and thats what I was thinking initially. I asked the sales guys at VMP if the 69mm would fit and honestly they wouldn't give me a definitive answer. They said that it 'SHOULD' fit and said that the VMP inlet elbow 'SHOULD' work. They didn't say yes outright, so I figured I...

Yeah, somewhere in that range. IronTerp posted this on a thread detailing step-by-step mods and dyno runs. The runs were on different dynos and probably different days, but the gains seem to be beyond just deviations, I could be wrong. Of course, I was stating the gains in the context of my...

Hi all, I am a bit torn here and haven't found good information on this exact topic yet. I've got a 2010 GT500 with a Stiegemeier ported M122 with a 2.2" pulley, JLT 123 intake, BBK 65 MM throttle body, and VMP inlet elbow. I plan on adding the 13/14 56# injectors and VMP fuel pump boosters...

Hi all, Looking to pick up VMP's Fuel Pump Booster setup for my GT500. The car is already modded and dyno tuned and running 18psi on a ported and 2.2" pullied Eaton. My recent data logs are showing that the fuel pumps are basically maxed out and so I figured going this route would work out...

I've got an M122 that I took off my 2010 GT500 some time ago and its got a 2.6" pulley on it. Its got about 50k miles on it and generally looks pretty good. Let me know if you're interested and I can shoot you over some pics.

Yes, so the “122” in M122 denotes 122 cubic inches, so that works out to 1.999 liters, so basically 2.0 liters to answer your question.

Thanks for the reply! Yes, I would imagine that would cause such an issue haha. Glad it has worked out for you though and based on what you're saying, my next mod will probably be the MGW. Sounds like there is a whole lot to be gained with out sacrificing much by switching to the MGW and the...
