anyone running that billet impeller from vortech? If so any gains? I've seen about 5 threads or so on the interwebz with no results.

Merry Christmas!

I did not hear anything positive.

I was talking to Josh @ A&A about the billet wheels for YSI and What i know is there never released the billet wheel as it didn't gain the power they were hoping for.

Vortech says it was a flop, a failure. lost massive midrange for no reasonable gains up top.

pretty much the ysi and 2000 the way they are are best bang for the buck and all around most reliable blowers take your pick one is quiet (2000) and one is noisy(ysi)

Still like the YSI.

That sucks!! so that stang TV article was full of bs then?

Based on what I can tell, the YSi is the blower you buy if you want to make 1000+ WHP in a "small blower" package without over spinning the heck out of it too much.

robert miller

Mike you are funny as hell blower and not wanting to spin the heck out of it to much & still make 1,k rwhp. Just put the 2.75 pulley on it and let it eat.

MVP'S ZO6

A 2.75 with an 8 inch crank pulley is over spinning it at 7K.

I have a 2.75 pulley on my YSi.

DOUG @ ECS

I'm testing one now, picked up over 1 lb of boost at 6k RPM. Still not finished tuning yet.

What kind of gains do you see going to a 2.75 from 2.85?

BLOWNBLUEZ06

Just repeating what I was told. I haven't seen the stang TV article.

robert miller

Doug how about a cart on both before and after the chg of that only.

Milan

I thought they gained up top but lost midrange.

Who cares about midrange? lol

Funny, just the announcement of a YSI billet wheel made most heads up drag racing classes add weight or not allow it.

MVP'S ZO6

Cool!! Keep us posted please.

BTW Merry Christmas! And F.U.

MVP'S ZO6

I believe you. :-)

Here's the stang TV article.

Well isn't that some ****!!

It would seem that if they are making the heads up classes add weight or not allowing it, that it's making some jam!!

Wish I could've had a cast vs billet comparison but we stopped at 1140/900 on breaking my engine in (engine dyno) w/billet wheel.

LSN 388ci (4.125 bore/3.625 stroke)
AFR 230's (older version)
ECS Big blower cam
Holley Hi ram 92mm
ID1300's
E85
2.95/8" pulley combo (21.5psi at 6800)

This was tuned at a timing map of 20* and we just crept up on it psi wise by changing pullies. I have no doubt it would've made 1200hp with fine tuning, better fuel pump voltage (notice the reulator psi dropping), and spinning it to 7000rpm. I may try the 2.75 pulley once the motor is back in and on the chassis dyno and just see where we end up.
