What do you intend to do with your car after the install, and what are the gains you are expecting? I'm only 15 minutes away from A&A's shop and had them do my install. My C6 is an 08 Z51 manual and their tune gives me 547RWHP @ 5800rpm. I asked for and got it CARB legal as I drive my Vette regularly on the street. I'm still on stock wheels and Michelin PS3+ tires, and it drives like a NA under 3000 rpm. Above that and in 1st and 2nd gears it will spin the rear tires and engage Traction Control, but from 3rd gear up there is a definite G force feel that makes me smile as the revs go up from 3500. If you do change out the wheels and tires to get a stickier tire you may want to consider doing a clutch upgrade as well, as that would be the weak link in the power transfer. Josh and Andy at A&A are both great to talk to about your plans, and since they've done so many of these they have a lot of good advice to help you get where you want your ride to be.
I'm guessing you're in Somis. I'm in Ventura by the way, so if you want to look at my setup you're welcome to PM me.

Thanks man. I plan on getting meth also for now. I don’t know if A&A will install that. I’ll drive it for awhile like that then probably get headers and maybe a cam at some point. I’m looking for a couple people to share the cost at renting drift practice track at willow springs. $1500. I got me and my neighbor and his dad so far. Both got built nitrous 90’s Z28. That goes for anyone in socal that would like to go in on track rental. I don’t know how many cars they allow but if allowed I would think 5 to seven cars would be cool. 9 hrs for $1500. One car at a time allowed on track and need spare rear tires and rims and helmet.
I’m planning on having my blower installed the end of March into April. I have a 2008 base model auto that is cam and FBO. Currently it makes 460 rwhp and 463 rwtq. My power should be jumping up to over 650 rwhp. I’m good with some lack of power down low being I’m planning on keeping the gear diff stock, 2:56. Plus i don’t drag or track race. I do plan on stepping up to 305 19‘s compared to my 285 19 rears. I’m more into roll ripping when I can downshift into 2nd at 50 mph.
I want to say the A&A guy posted 620rwhp no meth and 720rwhp with meth and SBE.
Pretty sure that means headers, cam to achieve at minimum.[/QUOTE
A&A recommends a meth kit if going over 600 rwhp
They are California based...maybe that 91oct. Some states have 93 or even 95. I wonder what 'acceptable' for 93?
-like I said I'm pretty sure I saw 620rwhp no meth and 720rwhp meth. Post mentioned something about them wanting to keep people from blowing motors to scrap parts and nothing salvageable....and knowing some go higher.
Spursby1 on YouTube and here did 800rwhp with meth and SBE, stock clutch (for awhile) for example. God knows how long that will last.
Price an LS3 and decide the risk/reward. I'm not sure you can get one for under $6k shipped

Hadn't thought about that being on 91 octane not 93 octane. I’m looking at 650 rwhp on once my A&A kit installed and trying to decide if I really need to spend the money for the meth kit. My installer tells me he gets 650 rwhp frequently with no meth kit to pull more timing from.

i am running A&A v3 ti 3.8 pulley.. btr cam 1 7/8” arh long tubes and Catless sbe making 683 rwhp no meth yet.
reason why no meth is $$ shortage ONLY!
did install circle D 3200-3400 rpm torque converter.. to hopefully dramatically improve 1.9 60’
Just had my stock 2011 C6Z with 30k mi done by Josh and Jesse @ AA Corvette, Oxnard and all i can say is big thanks for a job well done! Power everywhere and I couldnt ask for more.

Always put on the Meth Kit, it protects again poor fuel and detonation, massively lowers your IATs, and adds significant HP because you can run more timing. In addition, everyone thinks that because you made 650 whp on the dyno in March, you are making the same in August on the street, typically not the case. I've watched cars without Meth do hot pulls in summer on the dyno and drop 100 hp due to heat soak and the ECU pulling timing. That's why NA cars making the same HP will usually be faster all things considered.
Centri blower build boost up top. However they’re fun when they kick in! My c6z with a built 427 and a v1 ti on 8 psi made 832Whp on e40. From 4500rpm on it just takes off

can you show us what they did with the stock oil cooler?
4 inch pulley and 10%OD on a 8 rib setup. Definitely laggy down low. Will probably drop to a 3.6 pulley and let it eat it.
The gear ratio on a V1 is only 3.45:1 and you are using V-2/3 sized pulleys and a large SC pulley at that. The gear ratio on the V-2/3 SCs is 3.6:1.
With your set up the impeller speed is 46,920 at 6,800 RPM. Vortec puts the max at 55,000.
On a V-2/3 the impeller speed would be 48,960 at 6,800 RPM.
What you said makes sense. It would expect it to be be laggy down low and not wake up until 4,800. You are only using 72% of the superchargers capacity.
With a 3.4 you will reach 55,000 RPM impeller at 6,800 RPM.
You had me worried. I am having a 427 engine built and am looking to make 1,000 WHP or so with a Ti.
Put a 3.4" pulley on it and see what it does. It will be a world of difference. The increase is exponential. That means if you double the speed you square the force.
Can you post your cam card and flow specs on the heads please?

Yeah. I’m aware that these are geared slower than the v2/v3ti. But you can overspin these blowers supposedly. Someone is running a 3.125 pulley and 10%OD. That’s what I plan on doing. Heads are AI 280cc. Cam isn’t boost friendly at all and that doesn’t really help. 246/254 112 lsa 108icl .652/.630
