I know there are all kinds of opinions and that tuning and install has a lot to do with it, but I have narrowed down to either a A&A or Edelbrock E-Force to go on my 2012 Grand Sport dry sump. I drive it about 6,000 miles a year and do not want to stress over if it will break down, but want to be able to enjoy some drag days too. I had been told to go with Dallas Performance, but they quit working on Vettes recently so I am now leaning to either 21st Century Muscle Cars or Corvette World of Dallas - that's partially what led me to these options.
Anyway, my question is what have you had good or bad experiences with and has it lived up to what you expected so far. My idea is to go with the SC first and then might add headers and cam later - would love to go all at once, but that goes over budget right now. Appreciate any feedback and thanks in advance.

 

Tons of good shops in Texas. I would do a centri over a PD blower IMO.

 

There are so many people that love both that it will be difficult to make a decision based on that alone. You really need to experience both, or at least research the pros and cons on this site. Both probably have the same amount, but there is tons of info here. Imo, the centri gives you more flexability especially if you plan to upgrade later.

 

Quality Motorsports in Lewisville. You're close to them, and they have worked on quite a few blown cars in the area. They are an A&A dealer and did mine and a good friend of mine that lives in Frisco with a black GS. If you want no headache, very reliable, stick with the base A&A kit. Mine with just that and Z06 exhaust manifolds makes 600RWHP and has not had any issues. Pat (owner at QMS) focuses on reliability and will take care of you.

Other shops that I would also trust in the area are 21st Century Musclecars in Addison, LG Motorsports in Plano and TrueStreet in McKinney. Dallas Performance is good, but they are moving away from Corvettes and you'd need to be a previous customer to get in there.

 

Also, if you want a ride, let me know and we'll set something up. We've also got a weekly meet where a number of modded Corvette guys meet up if you want to swing by some time. 7PM every Sunday at Brick House in Plano. Thread is here.

 

Yep, a ride or better yet, a drive in each of what you're considering would be good. I'd lean toward an ECS kit if going centrifugal or a Magnuson Heartbeat if going p/d. Centrifugal would get the nod if you knew you wanted 700+ at the wheels. Heartbeat would be my choice if you were good with less.

 

Have a daughter getting married next weekend, but I will try to get out there some time soon after that.

 

Centri and take it to Advanced Modern Performance.

 

I agree 100%......i just finished up an A&A T trim blower w/ meth On my Ls2 m6. It is alot of fun (585whp), but if i had to do it all over again i would have went with a Magnusson heartbeat charger. I don't race at all....and for my style driving (spirited street) the heartbeat would be a better fit. I think i would enjoy the instant power better as you don't need to run the the rpm's up so high to get good power. Jmho

 

I think it's really a toss up between PD and Centri if you aren't going for 600+. The PD (Magnusson/Edelbrock) will give you more low end torque, while the Centri (A&A/ECS/Procharger) will make more peak HP. For me it came down to several things:

• Didn't feel I need any more low end TQ
• A&A installed from QMS was less than other options
• Edelbrock has potential heat soak issues, which is a concern in Dallas
• I didn't want to limit myself and may for Full Retard at some point and upgrade to a YSi or something crazy. Even with the stock Si head unit, I could max out around 700-750RWHP.

After living with it for a year, I'm 100% happy with my decisions. While a PD would give more low end TQ, the little Si actually does add TQ on the low end and make a noticeable difference from about 2500 on (probably 50lb-ft at 2500rpm). Traction with any blower (even the centri) becomes a major issue. I can blow the tires off in 1st, 2nd and typically 3rd, and have even had it break loose on WOT 3-4 shifts. I'm running 335/25R20 PS2s, and wish I had kept the stock 18/19 setup so I could have run something like NT05Rs in the rear. I'll be upgrading to M/T Street SS for around town to try and help with traction and keeping the PS2s for road trips. I've had no heat issues, yes the temp goes up after repeated runs, but they drop back very quickly (although I am considering adding meth for safety and more HP).

Would I have been happy with a PD blower, I'm sure I would have. My issue was they were $2K-$3K more installed than what I got my A&A installed for.

 

are you able to do the install yourself?... if so I'm sure dallas performance can still get the parts needed for their kit if that's what you really want, I believe they only use procharger headunits though... Taylor and all of his guys are great and have been very helpful with anything I have ever needed from them... as far as tuning I would highly recommend Bret (blownbluez06)... he may also be able to do the install for you and get a good deal on an a&a kit if that's what you decide to go with, just shoot him a pm

 

I briefly thought about installing myself and was originally between the e-force and heartbeat and had just enough advice that they were pretty much equal that I was going with the cheaper of the two. Then the guys at Corvette World told me they sell the A&A and what it could do, so I brought it into consideration too since it supposedly does not produce hardly any extra heat compared to the others. I looked at the instructions for installing the A&A and honestly it is well worth paying someone who knows more and has done them before. To me, the biggest drawback might be the noise of a centrifugal but I need to go look at cars that have them and get a better idea. I plan on getting the daughter married off, then a quick scuba trip in July and moving this into slot #3.

 

right on, well Bret can definitely help you out with anything you may need but he might be swamped right now you would just have to pm him to see what his schedule is like... some of the vortech headunits are really quiet, you would never known the car was blown if you didn't hear the bypass valve... now my procharger on the other hand is very loud and there is no doubt there is something going on under the hood but I wanted it that way... I believe procharger now offers helical cut gears which cuts down the noise level but I haven't personally heard one of those so I wouldn't be able to compare

 

People say they can hear mine (a&a t trim)....but i can't hear the blower at all inside the car, just the bov.

 

The Si trim is very quiet at idle, but the blow off valve can be loud when cruising and letting of the throttle.

 

I've been in the Vette game for 13+ years, since I bought my C5 new. Not sure if you have sigs turned on, but I currently own an LPE (Lingenfelter) TT C5Z and an LPE Supercharged C6 Grand Sport (Edelbrock E-force blower).

I bought the latter car from Corvette World actually. I don't know anything about their tuner/installer.

21st CMC did the TT install on my C5 over 10 years ago. That car runs extremely well, and has been very reliable. 21st CMC recently did headers and retuned the Edelbrock blower GS, and it runs extremely well too. I trust John and Matt completely. I had a '12 CTSV they did some work on... it ran perfectly. They did a cam/headers package on my son's C6...again, runs perfectly.

Pat at Quality is great, and so is Andy at ADM in Lewisville.

As far as which blower to go with... you've already gotten some great feedback above, and I don't disagree with any of it. Any of them will put a big smile on your face, and when tuned/set up properly, will provide great reliability. I've run, installed, and tuned a number of centrifugal blown cars back in the '90s. As others have said, they will provide the potential for more top-end, high-rpm power. They're just extremely efficient there. The PD blowers provide great power across the rev-range, but often give up some efficiency on the top-end when spun too hard (all blowers do eventually).

So a lot of it has to do with the type of driving you do.

I purchased the E-brock GS b/c I felt for the parts it already had on it, with the mint condition it was in + very low miles, I couldn't go wrong. See sig for power #s.

 

I have a procharger on my LS7 for the past couple years. I dont have time to race it but I do get a chance to drive it around town and its never given me any issues. I can hear the sc whistle, but it isnt too bad. 675whp/670wtq mustang dyno. no meth, just pump fuel. Other internal mods to get to those numbers, not just the sc
