Has anybody thought of doing a twin screw set up on their ZR1? I think it would be bad ***. I know the factory blower and supporting mods can be more than enough. I just thought it would be a cool build, although costly since whipple and KB are into a different market. There is a KB viper around indy that hauls ***, it made me think of this.

Kenny Bell doesn't make blower kits for the Viper. The kits are furnished by Roe Racing. Which technically Roe Racing isn't making them anymore either. Autorotor makes the blower and Roe Racing puts the kit together, or used to. How do I know. I have a Roe Racing 10# Blower kit and a 1997 Viper. Oh, btw, I would like to see someone make a bigger displacement blower for the ZR1. Would be a nice ad-on to my ZR1.

I was at Whipple last week dynoing a Ford GT that we just finished a 3.3L Whipplecharger upgrade on (678 RWHP) and I saw their new LS9 Camaro kit which just passed CARB with 608 RWHP at 9 psi and we discussed the fact that because they now have a CARB exemption number for the LS series engines, that they would like to to do a twin screw upgrade for the ZR-1. So, if anybody has a car here in CA that they would like to offer up for the R&D and be the first to get the Whipple kit; PM me and I will get you the necessary information to get in contact with the right person at Whipple.

Bump ...any news on a bigger blower for the zr1 ?

lt1z

I wouldn't put a KB on my lawnmower

I believe the mentioned 2 options . If it's reliable and makes a improvement why not ?

gkzr1

one of these options is in the process of being built now =)

👀👀 I wish I could find details , I was honestly hoping pro charger would have stepped up and made a kit since they made one for the c7 z06 but I don't see them doing it for a dying platform when new Cameros and mustangs are on the horizon .

Whipple is a fine blower other then requiring a new hood. I do not care for KBs. Never have. If you tune enough cars you start to see a trend and also if you take the blower apart and look at how they work things start to make sense.

You can use any of the c6 blower kits with an LS3 intake manifold pretty easily.

That sounds like a better plan than a roots style super charger .

That is what I would do if the stock blower isn't enough for you. It would set up accessory wise like an LS7

ylo73z

What accessories would be different from a ls9 to a Ls 7 besides the blower pulley ? I'm thinking after I change the heads for ported mast heads I'll ditch the factory super charger .

Any stock blowers for sale ?

But the only option is the 2.9 Whipple. That's not much of an upgrade over the stock blower. Unlike the Ford GT or GT500 you can't just drop a larger blower, like say the 4.0 ltr blower, on the LS9.

The 4.0ltr is available for the LS but it's very tall and wouldn't work on the corvette.

ylo73z

Maybe just go with a different hood ? I think I would lean towards a pro charger now that I think about it any ways ...maybe a turbo set up but I'm not sure if there is room for that

chuntington101

The 4.0 on top of any alas is VERY tall. It would probably stick fully out the hood of the car, even on a ZR1! Then there is the firewall issue and getting cold air to the intake of the supercharger. Again I just can't see it fitting.

However one company (dragon?) did a side mounted 3.3ltr whipple! However. I much ever came of them. There is no reason this couldn't work! However you need to think about filter location and the oil tank might get in the way on a ZR1.

Hope to see someone make some progress with an aftermarket blower setup

I think whatcop will be the first person to go for a big blower. After all he needs all the help with that havey engine block!
