You hear all sorts of stuff about supercharging the C7 but why not turbo? I guessing that turbos probably require a heck of a lot more R&D and being a new engine it will take some time but assuming there was a good turbo kit which would be the best way to go as far as cost, reliability, wear and tear on engine, etc?

 

turbos are better but out of most people's price range.

 

And like you said, a lot more R&D, work, etc to do it correctly IMO. I know my friends are working on one, and hope to have the 1st test car out soon, but production systems are probably 6-12 months out. Typically takes 2-3 mold revisions on the cast parts, etc. They don't just weld up some pipes and call it a kit, they do a lot of R&D, and cast all the parts for reliability. Then they won't release anything until several cars have 20k+ miles including winter, rain, and 115+ summer driving.

The fuel system really limits the cars anyways, so maxing out the fuel system on a turbo or SC isn't going to be vastly different. Once larger injectors/pumps/etc are far more common, and people are doing 800+ builds more often, then the turbos could shine, but for a stock car making 550-600rwhp, you can't beat an ECS kit.

 

LMR's Turbo kit is very well engineered and has been proven to work awesome. It costs more because it has alot more labor involved than just bolting on a supercharger system. A few cars making 800+ on their kit already. One even going 9's and i believe is about to go a whole lot faster.

 

Please tell me you are talking about AGP when you say my friends?
I spoke with Andy at Squash a few weeks ago he told me there making a fuel system kit to cover anybody's needs for any rang of hp. I would love to pair that with an AGP turbo kit. Just the thought of it makes the new Z06 even less attractive.

 

what about STS, does anyone know if they have anything in the works?

All things being equal say, which is the better way to go?

All things won't be equal.

Their kit will be probably 80-100% more than your ECS, A&A, ProCharger kits.

Turbo Lag will be a issue too.

At $10k+, you can get a ProCharger and have internals done.

 

Yeah, I just read that thread. As far as turbo lag goes, I could see there being a lag if you have a wimpy 4 cylinder but even with 0 boost you still have 460 bhp on tap, I doubt the lag would be perceivable.

 

My C6 with the STS kit didn't kick in until 3300? RPM, it was noticeable.

Compare it to any SC kit and it's noticeable.

 

Just depends on the kit and what turbo you go with.

 

the spool time of a turbo and actual turbo lag is not the same.

with turbo lag and you step on it the car feels like it's actually slowing down before it hits. as mentioned, with a big V8 you do not have this effect. both phenomenon are caused by the same principle of course, they are just slightly different effects depending on.....displacement, for which there is no substitute.

 

Here is another option these are good guys.

yes but it's not any slower than if it was stock, that's what I'm saying.

 

Started to answer this three times and kept stopping, I'll finish this time.

Turbos done right equals 3-4 times the cost of a super charger.

The SC's have gotten to be so cheap its very hard to beat. Me personally I like turbo's but after spending time driving my S4 I really do like the PD Superchargers.

I have spent most of the summer trying to decide what to do. Regular supercharger or a Root/PD style supercharger.

My concern is the PD blower will be impossible to drive. 500ft lbs of torque off idle sounds cool but sucks to drive. But they probably sound stock at idle and unless your on them not noticeable.

The other style SC makes power later on so less likely to blow the tires off plus I hate the rocks in a can sound of the regular SC's out there.

If there was a wide body kit out where Z06 sized wheels/tires would go on the car I'd get a PD blower, no questions.

My opinion on STS is a answer to a question no one should have asked. Turbos need heat in the exhaust and its all gone by the time it gets to the back of the car. All that piping to develop leaks, lots of tubing to pressurize to make boot, sounds like a drivability nightmare.

Winter is almost here, time to decide.

 

I disagree. In camaro and mustangs, turbos are actually same or cheaper than blowers. Only in vette land, where packaging sucks and they vette tax everything is it more expensive.

 

So does that change the fact that they are 3-4 times as expensive on the Corvette?

The packaging has a lot to do with it, as does the limited customer base. Things are cheap for Mustangs for the simple fact that the customer base is massive.

 

Interesting replies, thank you.

 

They are not 3-4x as much, typically 20-30% more, or not even that if you are looking at 800+hp setup.

At least on a c6, good blower kit is $5500, add headers, belt driver, etc and you are a solid $8-9k into it for a setup capable of 800-1000. A $10-11k turbo kit does that with the headers/etc so you need to look at the complete package. No need upgrade balancers, etc.

 

Will AGP add a vette tax when they release a kit for the c7? I can see it being a little more for a vette because of space & things being tighter on top of being new but some of the kits & parts offered as of now are just outrageous in price. I don't see how some company's offer a kit with actually less materials & charge more cause it's a vette. I'm mean look at the cost of headers compared to other GM cars. The only company's I have noticed not really price gouging the new c7 in performance is TSP & ECS & I hope I can add AGP to that short list when there kit becomes available.

 

Correct they are simply superior and way more fun, but typically at least double the price. But even on a 600rwhp car I just love the torque of turbos
