    Supercharger Installation Lead Times

    Paolo- You bring up a ton of great questions. 1) We will probably offer a kit without an intercooler as long as the customer is willing to live with not generating too much boost; something 6lbs and under will be ok without an intercooler. These applications will work great for somebody...

    1000+ HP Vipers streetable??

    Qui8ck answer to your question: Since it sounds like you know muscle cars; then you would probably understand why we decided to go the naturally aspirated route. All of our performance packages are NOT just a bunch of high power goodies. Each pacakge is designed to maintain the highest level of...

    1000+ HP Vipers streetable??

    What do you mean by streetable? Often times, people strive to acheive as much horsepower as you can squeeze out of the car. Depending on your goals, this may or may not be a noble philosophy. However, in many instances, people only use their cars on the street, as opposed to drag racing, etc...

    GTS Transmission

    If you really want something special that doesn't break the bank, may I suggest an upgraded T-56 with revised 5th and 6th gears. The difference in response and cruising is NIGHT AND DAY and you don't anything in the lower gears! I have it on my LETHAL 750 and the difference was amazing. Here's...

    Cam spec questions??

    We have used about a dozen different camshaft grinds for the Viper. All of our camshafts are designed for maximum drivabiltiy. This is why Car and Driver rated our 750hp naturally aspirated motor with the HIGHEST drivability rating for all the Vipers tested. Almost all of our camshaft profiles...

    Recommendations for shift lights?

    Ben- I think you have seen the one in my car before, right? You'll like it because it has a yellow backing cup. Very small and slim Autometer with mounting bracket and RPM box calibrated for a Viper. APEX has them in stock. If you want to see mine, let me know. -W

    It's all Doug Levin's fault !!!

    Re: It\'s all Doug Levin\'s fault !!! Ben- You are making many VCA members, including me, very jealous..... So, when are we going to see your yellow supercharged beast in action? Do you plan on going to APEX for a dyno? Weather has been chilly, so power should be GREAT! So, what do you think? -W

    Individual throttle bodies?

    We dyno tested a Viper with the 10 individual TB setup w/ carbon fiber. This car had a seriously built motorby Caldwell. Our conclusion was that this setup with such short runners was not well suited for most applications that see under 6500rpms. The torque and power dropoff below 5000 rpms was...

    #@#%$^ Doug Levin and dynos

    Ben- What about bringing your car down to APEX this week for a dyno? We'd love to see your beast in action....and with 5 straps I think we should be able to negate wheelspin... What do you think? -Wayne

    Tech help needed re: Tuning bugs

    Your misfire code is very common in cars with 'aggressive' camshaft profiles. You will probably notice that your car surges after this code appears. Your Viper must be a 2000 or later model year (most common years to trigger the code). We may be able to help you out. Call us on Tues (we are...

    Transmission for Viper GTS

    Just in case all of you were wondering just how much more of a PUNCH a Viper with one of these trannys has....here is an idea: 5th gear is now liking driving around with a 3.31 rear end ratio and 6th gear is comparable to driving around with a 3.85 rear end ratio. Pulling in 6th.....YOU BET...

    Transmission for Viper GTS

    Peter- GREAT TIMING! We just finished testing a transmission with revised 5th and 6th gears. We are now offering them as a complete unit, ready to install!!! The results are amazing. 6th gear can now be used on the street and pulls !! 5th gear is now very 'perky' too and pulls hard even from...

    LETHAL 750+ supercharger= LETHAL 1000? Nope...better!!

    Landspeed- Although I have never thought of a 800hp Viper 'slow' (unless you are comparing them to fighter jets!), I can agree with you that 1200hp is INSANE!! We aim to please Viper-crazed customers. After building 750+ hp on motor alone (I have been told that this is the most powerful...

    LETHAL 750+ supercharger= LETHAL 1000? Nope...better!!

    Bob- You've got mail. 'Our chef's special of the day is the LETHAL 1200.' Let's talk about upgrading your LETHAL 650 to a LETHAL 1200. I think you'll have enough power then...don't you? Hold on tight.... -Wayne

    LETHAL 750+ supercharger= LETHAL 1000? Nope...better!!

    As many of you know we are putting the finishing touches on the LETHAL 750+ package (LETHAL 750 with more aggressive cam, exclusive headers designed for 550 c.i., no cats, billet main caps for strength) for those who are not concerned with passing CA emissions/sniffers. The original LETHAL 750...

    91 Oct, CA, DLM Engine?...

    There are two 76 Gas stations that still have 100 octane unleaded pump gas. 1 is located in SF and the other in San Jose. I think you can arrange with them to get 50 or 100 gallon drums delivered to your residence. However, I might recommend that you get the timing retarded a enough so you can...

    Heffner 1000SCi Initial Driving Impressions (long)

    Gary- How does it feel to know that just about everything on the street (including most cycles) pale in comparison and are slow? Sounds like you truly have a wicked Viper!!! So, with all the power, at what speed do the tires plant on the street? I know that 750hp and 840 tq presents some...

    Sean Roe Supercharger - First Driving Impressions

    Varanus- We are closed on Mondays because we are opened all day on Saturdays. Call on Tues. and we'll see how soon we can schedule you in. We are currently out of tuning boxes but have some more on order. Should receive them in a week or two. Are you noticing pining before boost is activated? I...

    Sean Roe Supercharger - First Driving Impressions

    Most people don't realize that there is well over 40 degrees of timing in the Viper computer under tip-in/light to moderate load. This is A LOT OF TIMING!!! Yuck! I believe the MSD box should fix issues relating to pinging under WOT when you are seeing boost. I believe it is only a boost...

    Paxton supercharger for Gen II

    Greg- Good question. Luckily for us, this is not the case. For the last several years, we have been installing Vortech and Paxton superchargers (a few hundred) for the late model Ford Mustangs and Cobra Mustangs. Both of these kits include a computer chip that reprograms timing and fuel. The...

    Lots of talk about super-charging but is it really the right performance upgrade for

    With all of power that can be gained through parts going the naturally aspirated route, I wouldn't rule it out yet. Yes, the supercharger packages are generating some great power, but you can also see tremendous gains without going the forced induction route. The last LETHAL 650 package we...

    My Dyno Results

    What mods are you using to make that power? Is your car stock? We don't see cars making those power numbers unless they have headers, exhaust, no cats, filters and tubes. Is this your setup? If not, maybe our dyno is more conservative than I thought.

    Anyone install larger fuel rails before?

    Are you talking about 800 hp to the wheels or at the engine? If you are referring to 800hp at the engine (app. 680-700 at the wheels) , you should be able do it with proper tuning and properly sized injectors using the stock fuel system. -Wayne

    Anyone install larger fuel rails before?

    Why are you changing them? What type of power levels are you at? With properly sized injectors, we have seen, close to 700rwhp utilizing the stock rail in the intake, and there was still noticeable room to spare for more hp! -Wayne

    Looking for 500RWHP? No NOS pls!

    Your dream can indeed become a reality! There are many reputable tuners that can transform your Viper to these power levels. Many of them have aleady responded to your post. I am not sure where you are located, but, depending on your needs, it may make sense to choose a reputable tuner nearby...
