Well Im at it again with something else. My Z06 is at 700 rwhp right now but I want more. The TA is retired and Im about ready to get serious with my Z06. Going to memphis in it (LOL Or Im going to try) Ive got the 402 etc from my TA and Im going to refresh it. But I am kinda torn on what to get when it comes to Blowers. I dont want a turbo kit! There a PITA and I can work on blower cars all day long without Ive had a vortech before and made some serious HP with the Novi setup but I think the YSI can flow some air So Im looking for a some opinions. I did not mention procharger so dont start the procharger band wagon please!

Your friend's old 9s Silver ZO6 Had Novi 2000 right???
How much power did he make??

Maybe you should copy that setup it was sick.

Oh Procharger F T W
LOL

 

Both are proven, but I would take the Novi 2000.

 

The Novi 2000 is only 1400 CFM. This blower is more like Vortech's older YS supercharger. The Vortech YSi is 1650 CFM. I would go with the YSi. You could also use there new V-27 gear case which gives you a 4.25 step up.

 

the novi 2000 is a dinosaur blower there are alot better blower out there that flow more and are more efficient like a novi 2200

 

I think one of the biggest issues with blowers and C5 vettes is belt slip. You have to run a long belt through all the accessaries and it puts a lot of strain on your power streering pump, alternator etc.
Cartek has a new product called Flip Drive which allows you to use a shorter belt directly from the blower to your crank. On paper this seems like a great idea and Cartek has tested it on a 9 sec vette with awesome results. No real feedback from others as its a new product.
As for novi vs ysi, depends on how much power you want to make. The ysi should provide more potential as it flows more. The novi is physically a bigger blower, but is also quiter if you like that. As of late the ysi seems to be doing well, 8 sec zo6 on the vette forum. I would suggest you copy your friends car with the novi and add the Cartek Flip drive. You could then use an 8" crank pulley and gain an additional 2-3 psi! This should bring to over 900 rwhp and potential to run 8's with the right driveline mods!

 

Well personally I would go with the Novi 2000 they are one of the only blowers I know that you are able to put a smaller pulley than any other head unit on and not slip,but the YSI has proven itself time and time again so you wouldn't go wrong either way etc...

The Novi2000 is a proven blower with countless stock bottom-end C5's in the 9's. Yeah, the YSI does flow more and is powering the Fastest C6Z right now. Both ECS and A&A have a bad a$$ kit and you can't go wrong with either. You don't really hear about either kit having belt slip either considering the small pulleys many run. As mentioned above, with the Cartek Flip drive, belt problems should be a thing of the past.

 

Ive seen both blowers produce great numbers on various combinations but as mentioned above why not go to a larger procharger? With having someone such as they guys from EPP to support you.

 

Go YSi! Not sure if you'll have the hood clearance for it with the RMCR kit. You could go with a low mount kit that PSJ had.

good luck either way you can't go wrong!

 

Copied from corvetteforum.com:

Air Flow

Procharger:
P1 - 1200 CFM
D1 - 1400 CFM
F1A - 1650 CFM

Vortech:
S-Trim - 1000 CFM
Si-Trim - 1150CFM
SQ-Trim - 1000 CFM
T-Trim - 1200 CFM
Ysi - 1600 CFM

Paxton:
Novi 1200 - 1000 CFM
Novi 1500 - 1200 CFM
Novi 2000 - 1400 CFM
Novi 2200 - 1450 CFM

1000 CFM = 680 supportable HP
1200 CFM = 825 supportable HP
1400 CFM = 925 supportable HP
1600 CFM = 1200 supportable HP

 

In addition to this the Vortech and Paxton models use the same internals. A t-trim is identical to a novi 1500 for example. Same company.

 

900 rwhp.

 

This is going on my vette.

 

Im considering buying the cartek option. LOL Still on the fence.

 

Just some examples of what the YSI (A&A kit) is capable of: Brent (BLOWNBLUEZ06 on CF) is running a YSI on his 403 and making 911rwhp, 832rwtq. Also, Arun from Champion motors just put one on his 402 and is finishing up his build and shooting for close to 1000rwhp. I would just PM one of them If you need input from people who have the kit.

If I didn't go with a F1C I would definitely have went with the A&A YSI kit. If I encounter a hint of belt slip with my setup (shooting for 800rwhp for now) I'm getting the Flip drive for sure. I also bought the 8" Inovators West crank pulley. My car goes in for these upgrades next month so we'll see.

Good luck!

 

Ive installed both kits. And we are a dealer of both of them Just trying to get me off the fence. I think as of right now Im going to do a YSI.

 

I hear ya, it's a tough choice for sure.

 

**** that... I say go with a 3.3 KB twin screw

 

**** those blowers for this application a cyntrifical S/C will kill one of those cars just because of shear lack of traction down low with all that instant tq etc... I'm just saying LOL! But they will make good power. But in this application I think simple is better etc...
