I have to send my car into the shop to have a set of heads installed onto my car. After that, the only thing left to do is to do a short-block, which will be done. Part of installing the heads means removing the brackets and blower. As you can see from my sig, I'm running a NOVI 1500SL. My question is, should I swap out to a YSi blower now, or later. I've been told I can get the same numbers if I regulate the amount of boost. I'm not making a decision any time soon, but I do want to take advantage of any specials that may run during the holiday season.

What does everyone think about the swap? Yay or Nay?

[Camper]

why not just do the short block while it is torn down?

[Chris82xx]

I would but there are a few things preventing me right at this point. One of them being finances. I'm trying to stay within a budget this year and a shortblock puts me out of it. So right now it's just the heads, and if a blower swap would be a good decision, I can swing that. I know that the ysi is a much bigger blower, but I know that it can be restricted down to what I am at right now.

I would do it in a heartbeat, that YSI is the most efficient supercharger on the planet.

I did a before and after swap back in early 2010 on a stock LS3 as I recall it had 1/2 lb less boost and 10 more HP than the SI blower with the 3.8 pulley.

If you had done it on a T-trim, do you think the results would have been different? That's one of the parts I'm stuck on. I know that the Ysi is capable of much bigger heights, but would I be sacrificing numbers, or performance doing a restricted Ysi vs. an unrestricted T-trim like I am now?

Definitely upgrade to the bigger blower. It will benefit you in the future.

The SI is better than the T

[Chris82xx]

That's interesting. I always thought it was the opposite. But regardless, if I'm pushing 15lbs. of boost now, I could likely make the same power with less boost?

Hope you meant YSi cause there is no way a Si is better than anything.

Forgive me, it has been a while since I discussed all the impellers, I thought Vortech told me the SI was between the T and YSI

Maybe it is between the S and T.

Either Way put the YSI on.

Yes Sir.

The down fall from what I understand, but I'm not 100% sure is a loss in tq., or is that something that can be saved with the restrictor plate or a different pulley. I love, hands down, the pull the car has when it puts you back in the seat. There is also the option of a cog drive.

Dunno I still think the 3k or whatever your gonna spend on a YSI is better of spent on a shortblock. Why continue to push the limit of your stock block. I'd be building for reliability and not power at this point.

My next project I'm not even considering putting a power adder on it until I get the motor in.

A built motor isn't worth crap with a good tuner. Even the best parts can't hold up.

There are a lot of Camaros running the Ysi on a short-block. I've considered my driving habits and I don't see me pushing it. I'm also staying as close to the numbers I have now. So I wouldn't be pushing the motor more than I am now, and it would relieve stress on the blower. I've already priced out a new motor. It's about double of the Ysi. After this, my only upgrade is the shortblock.
