its $2200 from magnuson, but I need to talk to them again with regards to the inlet. That alone might be another 400 to machine.

If that's your total, nice price.

You have to ask yourself what you want to make for power.
The TVS will support boost levels up to 14-15psi without the need of an intercooler.

Which would be fine, since he has no plans of running an intercooler.

At what point do one of your maps you've posted on here show a limit on that 1320 you're using?

supposedly a local around here has vinnies old mp112 setup and is getting rid of it. why you gotta tempt meeeeee?!

**darkhorizon** · 12-21-2011

MP's look sweet.

They basically offer a 15whp gain on average though... hardly worth a crap compared to just about any other mod you can spend 4 digits on. Remember that it is still going to plasma inject well before it reaches levels of "spinning too fast" to be efficent. The real trick to these eaton blowers is the fact that blower speed has little to no effect on their effectiveness to make power.

Just to recapture the OP's requirements:

You want a unique blower setup that is "loud", non-intercooled, and mostly for eye-candy with the hood open, while you care minimally about power output.

Is that fair?

he would also like a root style blower.....so ha!

i dont have a problem with a twin screw blower, which isnt considered roots. i just want to make good power (upper 300s, low 400s) without switching to a turbo.

and yes i want it to be loud.

**SnowFlake** · 12-21-2011

What kind of gas will you be on?

My M90 was louder than anything.

With the silcencer ports left ALONE.

Realistically you can run any of the TVS blowers to about 20,000 rpm if you have the flow mods to handle all the air. I'm spinning my little 1320 16,000 rpm at 6300rpm on my 2.8 and I made 350whp without heads on a relatively small cam on 93 octane through a stock exhaust.

The little 1320 would have no problems seeing high 300s, low 400s with some heads and a custom spec'd (assuming you can spec it properly) cam.
You'd likely need not spin it much higher than where I'm at.

As for how loud it is, the blower gets louder with how small the pulley is. The TVS1900 would be pretty tame the pulley you'd need to run.

Our block is pretty thin as is

**darkhorizon** · 12-21-2011

Thats a pretty round number that 350whp... Conicidence!?

**Bio248** · 12-21-2011

dont you dare start a **** fest in my thread. i will end you.

so really the concensus is that i need a blower that i wont melt my pistons while still overdriving the hell out of it so i can some stupid whine. cool.

**CrazyGuy03** · 12-21-2011

Well according to blues video, a nice port job apparently makes it loud as hell

I like it

I think with a setup like Bio is going after he'd see a lot more power, even on 93.

**Bio248** · 12-21-2011

i am going to be running pump gas. the switch to e85 may or may not be down the road farther, but for now it is a pump gas build.

**Wotgtp** · 12-21-2011

Intenseracing made a blowzilla kit with a KB blower. I'd love to have one down the road. DAT WHINE.

**darkhorizon** · 12-21-2011

I want to know how you make 2 pulls that seperate horsepower by 50whp? I have seen those type of pulls via a locked TC... but not by like adding 2 degrees of timing or anything.
