Hey guys I went to the PBIR drag strip for the first time what a rush!!

This is what I have 2006 A6 L&G Street Headers,x-pipe, Corsa Sport exhaust no cats, K&N CAI, Diablo custom tune, stock tires, with this I attained my best of 12:43 that day, mind you I am a newbie on this,
I have 386 RWHP, my objective is to do better than 11:5 and get 600HP cost effectively as a daily driver no nitr. chime in guys need your help.

 

Cam/Stall/Fast/DR's and your there.

Ask Tony B4...

 

The 11.5 part is doable w/ the noted mods above no problem, as for 600hp both unrealistic & unecessary to accomplish goals. While you're at it I highly recommend porting the FAST & adding an u/d pulley when you do the cam. Cheap guarenteed HP.

 

I'm only making 14 more RWHP than you but my best time so far is 11.014 with a cam, headers, Vararam, 3:42 gears, 3600 stall converter and drag radials.

Without doing a single additional thing to your engine you should be able to run at least an 11.1 at the track by adding gears, stall and drag radials.

Blower.

 

It's not that easy to get to 11.1 with bolt-on's only. I know...Iv'e been trying. Only ONE bolt on car ever ran that fast and that is Dennis. I have the second best running bolt-on and I haven't achieved that ET yet. I believe your car is a rag top... if that is true your going to need a roll bar and a few more ponies that can only be achieved with the addition of a good DR's, CAI, Stall converter, Gears, Cam and Tune. Then and only then will you see those consistant low ET's.

 

I appreciate all the information please let me know if there is anything
more I need to consider.

 

I believe you have two very different goals here, which happen to coexist after a certain point.

600 hp, is going to be a ways off from where you are. The only realistic and or cost effective way to get there is with a supercharger/turbochargers/Nitrous. The blower with a cam, and some tuning will get you there, at a fair market cost.

Turbochargers, are a great solution for the power, but come at a much higher cost, install, and up front parts purchase.

Nitrous, this is a great option if you have a filling station near by, the initial cost of the kit is around 700-800 once you get the proper accessories. You can vary the amount of spray varying the amount of horsepower for desire, up to a mechanical limits of the engine. Obviously if you have a cam, heads, fast intake supporting modifications in general will yield you a higher net gain

Now in terms of quarter mile times, with your 600 horsepower, even on a stock convertor I would believe you could attain those times. Now if you simply want a better quarter mile time, and your current best of 12.4, you will need about 100 more horsepower to net the 11.5 range you are shooting for. You would also benefit from better tires, and stall converter!

There are a lot of different options for you to go with, nitrous being the best value, and still maintaining a lot of normal driving manner.

If you have more questions about specific type setups, a plan of attack, I can show you several customer cars which are similar to yours, and the E.T's they run.

Good luck!

You will run at least 11.5`s in any weather as long as you have the skills.

 

 

I see a few entries on Blowers what type is recommended also maintenance issues and intervals?

I met you on 11/22 at the Corvette Challenge...Iv'e got the yellow 08 LS3 coupe. If I were you I would talk to Roger from Horespower Sales in Pompano. They will give you what you want. They stand behind everything they do. They know Corvettes and how to make them run. Reasonable price and great sevice! GOOD LUCK

 

That's right how are you doing I will give roger a call later today ,are you going to be there for the citrus run?

 

I can't make it. I have to take care of some personal stuff...You now have the GO FAST BUG. The fun is about to begin.

 

Typically these questions prompt two things:
Forum vendors will tell you that THEIR kit is the best.
Forum members will tell you that whatever they happen to have in their car is the best.
These questions get asked a few times a week; we even have a sub forum for them, the FI/Nitrous section, and a search for "Supercharger" will provide you with ENDLESS reading material to answer your own question from a much more educated perspective...

That said, I will be happy to give you my own personal opinion:

In reality what is "recommended" depends on what you want from the car, how you are going to drive it, and what your budget is...
There are currently two choices for Supercharger kits for the C6:
Roots, and Centrifugal, with a 3rd in the works; the Twin Screw. I won't discuss twin screws but suffice it to say that it is very similar to a roots blower in that it mounts on top of the engine, requires an aftermarket hood, and produces instant low end torque, but it is a lot more efficient than the roots and does not show much of a drop off in torque and power at the end of the powerband.

If you want instant boost and tons of low end torque, you will want a positive displacement blower I.E. roots... Magnuson is the manufacturer for this kit and you will find it in Lingenfelter and Callaway cars. Cost is around $7500 - $8000+ depending on options. Add another $2000 for the install. These blowers mount on top of the engine, requiring a raised hood, which is additional cost and looks that some don't like. They make boost right away, producing huge gains in low end torque, which is very good, if you are, say, in 5th gear cruising through traffic and want to pass someone without downshifting, but maybe not quite so good if you are, say, in 1st gear trying to launch the car on street tires and instead just spinning them. There is also an Eaton TVS blower which is more efficient and makes more power, but also costs about twice as much.

Centrifugal superchargers come in 3 flavours: ATI Procharger, Paxton Novi, and Vortech: all are much more efficient than roots blowers, so you can make more power more easily. They do not require an aftermarket hood, so the car's looks remain stock, and they are also cheaper than roots blowers. Driveability wise, the difference is in where the boost is made: low end torque from centrifugal superchargers won't be quite as impressive until about the middle of the RPM range, from where the centrifugal supercharger continues making boost efficiently and goes on to make more power and torque than a comparable roots blower. Centrifugal cars can be made into very fast drag cars since the top of the power band is all you ever use in drag racing; there are a number of 10,9, and 8 second cars on this forum running centrifugals, and even a basic kit can earn you a 10 second pass with the right tires under the right conditions.
Centrifugals had a bad rep in the C5 days because of numerous issues with belts that slipped or broke, cars that overheated, and blowers that sounded anywhere from a can full of marbles to a power steering pump gone bad. While kits have gotten considerably better, the general consensus is that you are better off buying them from a shop that also installs them themselves, as those kits tend to go through more revisions and thus have fewer issues... The two more popular kits right now are ECS (East Coast Supercharging) and A&A. ECS uses Paxton Novi blowers whereas A&A uses Vortech. Both are virtually identical but Vortech blowers are CARB certified, and also somewhat quieter if you get the "SQ" (Super Quiet) variant.
Maintenance wise, you are given the choice of either a self oiled or an engine oiled blower. With the engine oiled blower you continue to follow your engine's oil change interval and the blower oil gets changed along with it. With the self oiled blower you have to change the blower oil separately during your engine oil change. Belts need to be replaced every 30,000 or so miles depending on boost level and usage.

I personally ended up going with A&As kit for my car because it was considerably cheaper (they are on sale now for $4500 for a base kit, $5200 for the higher end kit I got using a polished blower and A&A's new Ram-Air intercooler) and because I felt it had te better belt tensioner and intercooler design. That's less than half what you would spend at Lingenfelter; you can have the complete kit installed right now for less than $7K at Vette Doctors.

Different drivers may look for different things from their car For me, personally, I am really happy with my A&A kit; my car looks and sounds stock and I can still daily drive it to work in the rain, yet it makes 597WHP / 518ft-lbs torque and is unbelievably fast on boost... I could make much more with a bigger blower for instance, but at those power levels you start to run into some traction issues on the street, so, again, you have to make some decisions regarding tire choice and intended usage before you decide what is best for you... Any supercharger kit will net you at least 600crank HP and be good for those 11.5 second passes you want on any weather... From there, the specifics are up to you...

Good luck and let us know if you have any specific questions

 

rims & tires

 

Already wanting to go faster, huh! I knew the bug bit you, but not quite that bad!

One thing to keep in mind is that you don't want to run under 11.5, or you will be required to have a 5 point roll cage installed. Of course, if you don't mind the roll cage, then go for 10's. I agree with getting with Roger. He will be able to guide you to your goal. Another option instead of supercharging is nitrous.

 

Blower, cam, heads, exhaust and a good tune and your close

 

You can make over 650WHP with a blower; adding heads/cam is unecessary.
