I'm pretty sure mine is the highest HP on boost without supplemental fuel (i.e., race gas) or nitrous. My car made 843 rwhp with 93 octane pump gas.

The best ET on boost only for my car is 10.20 sec. I use a Vortech JT trim.

Highest boost-only figure I've seen is low 900s from a [******] Turbo car. Highest boost-only supercharger figures I'm aware of are from my yellow car, currently at 868 RWHP / 853 RWTQ (SAE). Highest SC 93-octane pump figures are GaryA's car @ 843 / 792...

I'll be posting the numbers for the LETHAL 1000 in the next week or so. Our goals for the setup will be the following:
1) Pump gas, not race gas
2) No intercooler; we are only going to make about 6lbs boost which does not justify an intercooler
3) No additional injectors, no external fuel rails (retain stock engine look)
4) Stock fuel tank
5) CARB certified supercharger package (leagal in all 50 states)
6) This package is being added to my LETHAL 750 package. When you start with 750hp on engine alone, we don't need to add a ton of boost to reach 1000, and hot air/heat issues are not present. However, depending on the numbers we may try to shoot for some crazy numbers (although we may end up de-tuning for street driving to around 800-850rwhp..hypothetically speaking). Given the fact we are starting with over 670rwtq, I feel like our torque number will be quite high!

Stay tuned!!!!

Since my last post, I received several e-mails questioning why we don't go with more than 6 lbs. boost. The answer is very simple: Because we don't want to. It's the frequently discussed laws of physics. After certain thresholds, your car will not be able to get any traction. Anything above this threshold I would call wasted horsepower (power that can be planted to the pavement at 'reasonable' speeds). Most of our customers (over 95%) use their cars on the street and occassional road courses, autocrosses, etc.. Few (very few) bring it to the dragstrip. Sounds like other areas of the US have a totally different customer distribution that primarily goes to the strip. On the street it is not uncommon for a car with less horsepower to accelerate faster 0-60 or 0-100 than a car with a ton of horsepower because of traction.

As I stated before, with only 6lbs boost, the engine is not being pushed nearly as hard as 10-12lbs boost. We do not need an intercooler, heat issues will not become present, and the installation is cleaner and more simple with less points of potential failure.

Longevity, reliability, and drivability have always been our primary objectives for any package we build.
Thanks for your questions.
