Ok I am just gathering information here. Please feel free to help in any way you can.

I am looking to get my C5 Auto into the 12s I am thinking that forced induction is my best bet.

First question how much HP/TQ can these cars generally handle with stock internals rear end and transmission.

Also what kind of price range am I looking at? I am not asking for exact prices just looking for a basic range to start thinking about. I know on my 01 Mustang I was looking at about 3k for a kit without fuel pump and injectors. How about for my C5? How are the stock injectors and pump?

Thanks for any help. I checked on line for pricing but just about everyone says to call and I hate calling for prices when I am not ready to purchase.

 

One other question. I know on a lot of other forums people sometimes distrust the STS system. Does anyone here have an STS Turbo system? How is it. Is it the system a lot of people claim it is? Thanks again

 

Figure roughly double what you payed for your Mustang kit as entry-level for a Corvette kit. Triple it if you're interested in front-mount, hard hitting turbo setups.

Best bet on getting info on the STS kit is to use the search feature. Plenty of guys here are running STS.

 

diynoob's numbers seem to be good to me, assuming your going to do the install yourself.

If your going to pay, figure 9k for a blower, 18 for twin turbo's.

Then start adding money for breakage. If you think your going to run the car at the track a lot, add 2-3 k for a tranny, and some extra money for the potential of rear end work.

If you just want a quick vette, the 9k will do it, but dont think your going to beat on it a lot and get away with it. The blower will get you ~500 hp. The tranny's good for 400. So its on borrowed time day one.

 

If you just want to run 12's... Put some gears in the car and maybe headers -

Most 6spd c5's run high/mid 12's stock

 

solid 12's only require LT's, better gears, and sticky tires.

add a blower to that and you are looking at 10's

More Than Zero

 

Got any links to those threads on the other forums about "sometimes distrust the STS system"? I'd like to read them since I am planning on (hoping, actually) to get my STS system installed next week.

Thanks.

 

Your other option for easy low 12s/mid 11s is drop a 402LS2 in it. For about the same $$$ $9K or less if you do your own work, you have a brand new forged motor and you can run 12s easy...

 

Just get a head and cam and LT 12's all day long on street tires

 

I have heard a couple people on LS1.com and a couple mustang board ragging on the STS Systems.

Nothing specific. Just stuff like comments about STS systems being dyno queens and such.

 

There are several very happy STS TT kit owners on this forum. STS makes a fine TT kit for the C5. Some will rag on it as they can't seem to get their head around the idea of a rear mounted TT system. I have an A4 coupe and was looking for a fast, reliable daily driver, not a dyno queen or something I could set the land world speed record with. My base STS kit was professionally installed in Jan 06. I have since put 8K miles on the kit and have not had a single issue with it. My STS kit includes the base turbos, single waste gate, quad tips, .36AR turbo housings, and 60 lbs injectors. The shop that installed the kit also added a few minor mods to the kit by installing an oil catch can, breather (replacing the oil filler cap), and routing the kit's oil return line to the passenger side valve cover instead back to the oil filler cap. Others with this kit have also upgraded their valve springs to avoid float. I have not. On a 100% stock LS1 motor, thru 3600 stall TC and 3.73 gears, I dynoed at 446RWHP, 420RWTQ. This is on 5/6 lbs. of boost on 93 octane gas with a conservative tune. Professional installation including all parts, labor and dyno tuning was around $8,500. I start to get into boost about 2K RPMs and the car pulls like a **** all the way up until the tranny shifts. With the .36AR housing, I also get the coolest whistling sound when the turbos spool up. Very happy with the results as I achieved what I was looking for out of the car and kit. I can easily expand on the power this kit is capable of when my budget permits. Other members on this forum have put the base kit on forged motors and turned up the base turbos to 12 lbs or higher of boost. They have achieved well over 700RWHP. The point is that the kit will easily put down big numbers if you upgrade the supporting stuff (forged motors, upgraded driveline, fuel, etc.) You would need to do that with any FI system anyway, it's not unique to STS. A couple of these built cars have run the 1/4 in the 9's. And, STS customer service is great.

Regarding your question regarding how much RWHP a C5 can handle with stock internals, the general consensus seems to be to keep it at or below 550RWHP and/or 7 lbs of boost with a good tune.

 

Great info.

Those are all viable sollutions but for under 1 grand, throw a 100 shot of NO2 and you'll be well into the 12s.
