New Generation Eaton Blower


Hook 'em Horns! And Vince Young is playing as I type this....go Oilers, er Titans! :biggrin

Oh yeah? Will take a look at who he hand'n off to!:biggrin
 
Because the ZR1 will come from the factory supercharged, I wonder if with a new, bigger blower, will it be able to make mucho hp easily?

I doubt that a bigger blower is going to fit would modifing the intercooler that sits above the blower, but I am sure that the aftermarket will have kits to boost the power.
 
..... those twisty hill country roads were even fun in the CL65.

If any of you TX guys are up for a Hill Country run....I'm in....and we can meet at Corey shop for some dyno fun. Spirit....what do you say??

Yep, I love these Hill Country roads.:thumbsup

:cheers

You're right....maybe that's why they lost. :wink

So let me get this straight, if they win it's due to the quarterback and if the lose it's because of the running back?:confused That really cuts to the bone Doc.

Actually it was Chris Brown with that crucial fumble in the first quarter....so I can't blame LenDale or USC.

I really thought my boys were gonna pull it off there until the 3rd quarter...:frown
 
Stormcat, the new vette actually uses the 2300 (2.3 liter). 35% less parasitic is really, really off from fact. If thats so, what in the world were they selling to everybody before?

Thanks,

Dustin,
Some of this this info was taken from the write up in Autoweek Dec. 24th issue and some info was reported by another writer in the recent Car and Drive issue. Car and Driver reported it to be an R 1900 unit. Someone may have provided the wrong info the the writer. I've got to think GM has but a lot of test time on these units. Both mag articles report they are quieter and more efficient.... I'm not claiming to be an SC expert I just reported what I read...

Autoweek reports the ZR1 has two inter coolers that are on each side of the blower not an above below configuration as on the GT.
 
Brian, take a look at these picture. It appears that the supercharger fits tightly in the middle of the intake manifold, blows up between the intercooler, then the air goes through the intercooler towards the sides and down into the intake ports. A bigger blower would require a new intake and intercooler, plus raising the hood.

Thats chevy engineering for you :thumbsdow

good luck working with that :lol

i could put a 3.3L whipple on my GT in less than a day with no mods to the hood, intercooler and or cooling system :wink

The Ford GT is a real american supercar :usa

That a good view of the parts. The articles I read didn't show that much detail. The description made it sound like the intercoolers are more spread to the sides under those blue covers which allowed them to reduce the total height and not have a large hood bulge. Good find on the photos..

I think you're right, look at the silver engine cover that sits inside the blue one. You can see the holes for the intercooler hoses.
 
I'll make the fearless prediction that a stock ZR1 will give a pullied FGT a good run for its money.

The fact that the GT can make 1000 HP with stock internals and fuel system just tells me that the car was released "under tuned". It should have had the 2.75" pulley and 600-630 HP out of the box...
 
What is the parasitic loss for whipple 3.3 when it's making close to max boost in the GT?

At 19psi, roughly 70hp.
 
Great information, Dustin. I wonder if there is room for a Whipple under the ZR1's intercooler? :biggrin

Has anyone seen the Roush/TVS blower upgrade for the GT500? Is it the same blower under the ZR1's hood window?


Not much room under there, especially since the casted it in an integral housing. They also are driving the rotor from the rear shaft, which complicates matters. We have something in the works for a new project were working on.

Although that SC is at max rpm, there is still a bit of room for smaller pulley's, I think you can get another 10% without much worries. So smaller pulley's will become a popular upgrade.

The Roush/FRPP TVS blower upgrade is the same rotors, but driven in a traditional fashion. As others have already found out, with the packaged pulley, compressor speed over 15,000rpm, the SC is only producing 12psi and 600-620rwhp range. Because it can't flow enough air, it can't get into the 800rwhp range.

Thanks,
Dustin
 
Dustin, I want a Whipple but I am waiting for the new Whipple. Please give us some info! I want more power!

New rotor profile, up to 15% increase in airflow which allows for lower compressor speeds to equal same flow, which lowers temps and power consumption (parasitic). Gains will be in the 20-40hp range depending on boost levels and tuning.

Thanks,
Dustin

I'm actually working on something, and yes, a bigger, more efficienct SC will make more power, although the block is not build for more than 650, I think it can somewhat safely go to 720hp in aftermarket trim.

Thanks,

No problem, but it's certainly a 2300 (2.3L). I know a few of the engineers that worked on the program, and they're incredibly happy, but if we could make the screw for 1/4 of the current cost, there is a good chance it would've been on there. So, in OE, the bang for the buck of the TVS was great.

Thanks

The one thing about the TVS is that the rotor is approx. 112mm, which defines it's width. I have a new SC that is 3.3 liter (different than current) and it's 112mm in width, which allows us to cast a replacement housing, with rear rotor drive housing. Should be very interesting.

Thanks,
Dustin
