How would the ZL1 do with the TVS 2.3 Blower? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Im firmly convinced the difference between the ZL1 and GT500 in straightline performance is that the Shelby has the bigger supercharger pushing more boost. Sure the camaro is roughly 20 C.I.s bigger, but the Shelby is maxed out as far as Cubic Inches.

So my question is, with the bigger supercharger, pushing more boost (15 like the Mustang) would the Zl1 be as fast or faster than the Shelby? Even with its weight penalty?

At that point it will be a numbers thing , LB/ horse .And the driver will make it work on his/hers favor

HOnestly I feel that GM should have went with the 2.3 from the get go. a 1.9 is pretty small for a 6.2l engine. Granted we are getting 580 out of it but the 2.3 would be more effecient and would have lower IATs with it.

Im sure the Cobras heads flow a bit more than the LSA heads as well.

I think GM intended to put the 1.9 on this version of the ZL1. And will have the 2.3 Blower on in a few years. Hopefully they wont be behind by then.

Ill be happy when Whipple comes out with its 2.9 or 3.4 for it

Are they? Will it even clear the ZL1 hood?

Im more trying to compare the two all things being equal. Id venture to guess the ZLQ would be faster than the Shelby with the same size TVS pushing the same amount of boost. A TVS 2.3 pushing 15lbs would probably push a ZL1 close to 690/670 torque

Every aspect of the ZL-1 was nit picked by the safety engineers and lawyers at GM. If the performance engineers had their way the ZL-1 would be well over 600hp and with some of the best components available. To include a larger supercharger.

I disagree, it was nit picked over by the comptrollers and financers and then the engineers were left with the bits and pieces to try to built us something on a limited budget and a small time frame. If it was left to the engineers they would have built a better head, used forged pistons and a larger blower.

I emailed whipple about 4 months ago. They told me they are working on a program for the ZL1 so we will see how it fits when they release it

I have said this from the beginning . If the ZL1 had a bigger blower at 15 pounds they would be making over 650 hp. Even with just a CAI,pulley and a tune a 1.9 zl1 will make almost 600rw.

I say GM needs to build the ZL1 with an ls9 cam and a 2.3 blower @ 12 pounds. A stock 680HP zl1 sounds good to me.

But there's a little problem with that because the ford motor is forged with all the good stuff the lsa is not

Yeah... If I ever wanted a 1000 hp monster... I'd be more comfortable with the ZL1

I'm a Ford guy and I own 6 Mustangs my self so I'm not bashing you because I'm a ZL1 guy but I have to say that if you don't know what your talking about then don't say anything at all.
I have some friends with ls2s and ls3s that are making well over 600rw and some over 700 and they have never had a problem.
A zl1 with the right tune will live a long life at 650rw.

I think it comes down to car MSRP, and being price competitive with the direct competition. The LSA makes the MSRP x price, and the car then is price competitive. The LS9 kills that equation because of all the titanium. An LS9, less the ti.... now you've got the cost of a new engine development... So, just my opinion, they went the route of off the shelf engine availability that met a specific MSRP target.

Shoulda woulda coulda.... is nice to wish for better stuff out of the gate, but if it skyrockets the MSRP what is the point. How have the vette sales been doing with all those super editions.... GS, Z06, ZR1.... sales have been in the toilet. Just a guess for a reason, but check the sticker prices. When Vette prices started going through the roof, they saw my last Vette purchase with a C5 Z06. Love the Z06, but not a rediculous prices. Same thing with the ZL1 for me. If the price is kept reasonable, I may own one in a year or two. If it goes to rediculous levels like the Vette did, forget it.
