    890 rwhp/840 rwtq ( LETHAL 750 + Heffner SCi )

    Great numbers MASH! Well done Jason! For those who were wondering about the power levels the LETHAL 750 made on Mash's motor alone, here are some points of clarification: 1) MASH's LETHAL 750 was not our typical LETHAL 750 package. We built his with significantly less compression than the...

    Paxton supercharger from Summit racing

    J Smith- This is a new 'kit' that Paxton is offering for Vipers. It is the ONLY 50 State Carb certified/CA street legal kit that I know of for Vipers. They tested it on a couple Vipers for quite some time. We worked on the Viper that had it on for over a year I believe. I plan on posting dyno...

    Paxton supercharger from Summit racing

    This is the same kit we just installed on my 2001 LETHAL 750. Finished the installation yesterday. Few corrections: This kit is for a GEN 2 only It does not come with an MSD box, it comes with a pre-preogrammed timing calibrator box. On a stock car it should yield around 7.5 lbs boost It is a...

    Viper World: I need your support to prove the Viper is still the best!!

    Kent- Thanks for the tips.... Keep in mind that this is THE SAME car with the same bulletproof engine platform that was tested by Car and Driver (making over 750hp) in the Supercar Challenge. We spent 1000's of hours with R&D, inspection, driving, reinspection, further strengthening the...

    Viper World: I need your support to prove the Viper is still the best!!

    One last push!!! We need to make sure there are Vipers in this event to crush the imports!!! Repeat after me: There is NO replacement for displacement!!! I hope both Paolo and I can make it. Then there can be some healthy 'inter-competition' within the overall competition!!!

    all motor limitations

    I felt like we maxed out the motor for a daily driver with our LETHAL 750 package that made 671 rwhp and 712 rwtq. Drivability was great; Car and Driver gave it the highest rating of any Viper tested. Coincidentally, it was right at the limit of traction in 2nd gear so it works great on the...

    Viper World: I need your support to prove the Viper is still the best!!

    Viperzilla- This is why it is SOOOOO important that we get votes from the Viper community. The import owners easily outnumber us. Every vote counts, and, based upon last year's results, it will be more challenging for a Viper to make the cut!! Group effort! -Wayne

    Viper World: I need your support to prove the Viper is still the best!!

    Like I said earlier, I hope both Vipers make it for a stronger showing. It would really put an interesting Viper twist on the event. I feel like we could do well in the dyno portion as they compute points off of the average power torque (I was making 600rwtq at 3000rpms before the supercharger)...

    Viper World: I need your support to prove the Viper is still the best!!

    Paolo- I just picked up my copy as well. Hugh brings up a good point....why so quiet about it?? I hope we can both make it!! It will be a blast; we should shred most of the competition! Are you holding out on us??? An 1100hp (935 rwhp) supercharged Viper!! Wow...now I have to up the ante on...

    Viper World: I need your support to prove the Viper is still the best!!

    jkracer9- Great questions.... This is truly a unique competition. Details below: The 10 cars with the most votes compete against each other in a number of tests including drag racing (0-60, 0-100, 1/4 mile, etc..) during which you can use STICKY tires, street driving/drivability, road...

    Viper world: I need your support!!

    All: After my LETHAL 750 2001 ACR was tested in the Car and Driver Supercar Challenge last fall, I know there were some good questions raised about what my car was truly capable of, particularly for acceleration!! Since they did NOT test cars at a dragstrip for acceleration, and cars were only...

    Thanks Buckeye!! I think you should be able to find it at Barnes and Noble or even the local supermarket by this time. I think it already hit the newsstands here. -Wayne

    Emissions Legal Supercharger Package

    Paolo- Thanks for your continued interest. The reason the dyno has taken a little longer than expected was really because APEX was waiting on a couple key parts from Paxton. Since I think my car my have the first production kit, parts were coming in on a daily basis. Some took longer than...

    Emissions Legal Supercharger Package

    Sounds like the same kit to me. Paxton only makes 1 or the Viper and it does offer an air-to-water intercooler. -Wayne

Yes, it is smog legal and CARB CERTIFIED!! Just finished the installation today, we will dyno and tune early next week. APEX...

    MASH- Great to hear you are enjoying your LETHAL 750. I'll be sending you an e-mail with the dyno. Putting the finishing touches on it today. -Wayne

    Looking for rear muffler (MI)

    I have a pair of rear mufflers with a custom X-pipe (has a great exhaust note as a result) that we made for my Viper. I could be persuaded to sell it. THe mufflers are 2 round Stainless/Chrome Dynomax Ultaflo ones. -Wayne

    Quick update on LETHAL 1000 progress....

    I appreciate the interest level I have been hearing from you. As promised, I thought I would provide you with a brief update on my LETHAL 1000 progress. Package is installed!!! So far, our goals have been met: 1) They were able to use an aftermarket radiator (Fluidyne), despite the...

    California sniffer-proof mods?

    Currently most of CA uses a sniffer test. Put a pipe in your tailpipe and measure emissions output at idle and 2500 rpms. Interestingly, we have seen some high flow cats that others use, flow soooo much that they do not heat up enough to 'light up' and burn off emissions. As a result, some cars...

    California sniffer-proof mods?

    Thanks for the input and postitive feedback. You are correct! APEX does offer packages that pass the emissions sniffer. We will be posting numbers on our the NEW truly CARB certified (not only sniffer legal, but CARB legal!) SUPERCHARGER system! They can add this supercharger package to any of...

    New Lethal 750 dyno numbers

    Torquemonster- I think 750 hp and 800 tq is plenty for the street! When I drive the car, I feel like it is right at the limit of adhesion for the tires through 3rd gear, but somehow the tires stick most of the time. If 1000hp is what your goal is, I can tell you that you will be wasting...

    New Lethal 750 dyno numbers

    Torquemonster- Looks like you dug this one up from awhile back. We spent hundreds of hours testing all sorts of naturally aspirated parts on Vipers to come up with the LETHAL 750. Our goal was that we wanted a car that was mild mannered enough for the street, but had ungodly amounts of...
