Currently rocking the TiV3. This build this year will be my last build for a few years so I want to make the right choice. Im going to have a 388 or so built. Cant decide on keeping the Ti or upgrading to a YSI. The YSI would be pullied down. I also like the sound of the YSI. Josh says I can do a 8rib set up with their direct drive so I will be going that route if I go YSI. The car goes to the track hopefully once a month this year. I know the YSI will trap more, just concerned it will be slower until 3rd gear or so. Id rather have more steam to 120mph than have the car come alive at 80mph plus. I guess my main worry is it will act like the big turbo cars do, the ones that get their *** kicked on the street until they hit 120ish or so.

I have a YSI, with the stock motor and a 3.0" 8.25" combo the setup was very laggy. I now have a 402 with a 2.7 pulley and it works great. Keep in mind I live in Denver so my setup doesn't make as much boost as it would at lower elevations.

Well that’s lame lol. My TI is maxed almost right now, that’s why I’m thinking YSI. I was thinking 402 and ysi.

Running a YSI with 3.0 pulley on a 402. Definitely not laggy.

A Ti trim turned up into the mid 800whp range is a great street setup. Won't win all the races but reliability and fun factor is still there compared to the 4 digit setups

If I had to do it again, I would do a Ti trim, ~750rwhp and call it a day. Assuming I didn't just do a solid 550rwhp NA setup.

I’m running a maxed out Ti trim on my Z making 837whp. It’s already a handful on the street and wouldn’t want to run a YSI for a car that primarily sees street duty.

what size pulley?

Patriot Six

A&A secondary drive with 8 rib, stock size balancer and 3.47 blower pulley.

I'm running a v2 ti-trim w/3.4" pulley on a stock diameter Ls2 balancer (6 rib). not sure if your setup (secondary drive) spins at same rate.....? I'm at 13.4 lbs....what are these blowers capable of? am I close to its max? never dynoed

Patriot Six

Yours is an HD version so you can spin it a little bit harder. If you’re going to do that, I would go with the secondary drive and overdrive balancer (8 rib). I picked up 2psi just with the secondary drive running the same blower pulley size as well.

Been there done that, keep your TI and put a good set of pistons and rods in your stock block. Will be run and reliable.

Podium

I’m going to do that. Build something similar to your motor with the ls3 style top end. I think I’m going to switch over to the secondary drive with the 8 inch IW, 8 rib set up.


Thanks for the comments every one and talking me out of it lol.

Podium

I think you are the max speed that is recommended by Vortech. You can go more being an oil fed unit.

I hit 13 psi (average 12ish) at 6.8k with the 3.6 and ATI stock size balancer and the current AA kit

algZO6

save your money and use your stock block and crank unless you have money to burn lol

Curious on why a YSI isnt as street friendly? I figured street manners were close to the same on all centrifugal blowers.

Unreal

Race blower, means no warranty, loud, noisey, bearings typically don't last as long, and bigger wheel means harder to spin and not efficient until it is in its happy range. Unless you want 950+ no reason to go Ysi besides bragging to friends or showing off at a dick measuring contest.

It is street friendly, just a waste and pointless to run for 750-800rwhp when the Ti will work better.

I would recommend completely maxing out your Ti-trim before considering an upgrade. For the street, a Ti has plenty of power potential. I had a V1 S-trim almost 20 years ago that I was spining past it's redline (8 rib) and could blow the tires off in 4th gear of my T56 by simply rolling into the throttle. I didn't even have to floor it. That blower was bullet proof reliable, too.

Millennium FRC

What RPM are you spinning it to?

Podium

That was due to poor suspension or poor tires.

I spin mine to 6.8k or so
