We have been installing superchargers on the LS1 base engine for over 2 years now and have several H2s with chargers on the streets. In the next 2 weeks we will be testing our 750HP H2 with our 410ci stroked, supercharged engine. The stock H2 engine can handle 6 to 7 lbs of boost all day long with no problems. The 4l60E trans has handled about 700HP without having any problems. The background of our company is racing both NHRA and SCCA road racing. We are constantly pushing the limit on these vehicles to see what they will handle. As for Lingenfelter they do have good products and do good work. Actually they are one of our dealers for some of our products as are we of there’s. If anyone wishes to discuss the supercharger issue or Head & Cam please give us a call.

Thank You, Ernie

Ed,

Mine on order is to haul my family also. But when they are not with me I wanted to get the rush of 100+ mph. That pic has me doing some serious thinking. (I crashed a vette doing 110 and only got a broken arm) fortunately it started spinning to the right and the left rear qtr panel hit stationary light pole & I was thrown out the opened drivers door. God wanted me to stick around and have the 5 kids that I didn't have back then! They all can't wait for this "monster truck" as they refer to it....to get delivered!

Clay,

You can't go past 97 MPH on an H2 bec there is a gas cut off for safety reasons...and power will return once MPH is less then 97...so you will not be able to get a rush going 100+++ bec it won't be possible...if you modify the engine or adjust the computer, fuses, etc., that is another story...but stock will not happen. Sorry...

Remember that the transmission is a 4L65E (a beefed up 4L60E). Chevrolet mates a 4L80E with the 6 liter engine rated @ 300hp. and 360lb. torque in their truck line. More torque might load the load the tranny pretty hard.

There is this thing called transmission, if you need more power, your shift gears. 20 years ago, real men, or real women, drive stickshift only, automatic transmission was an optional luxury item. I used to look down on people who drive automatic, until I got my first automatic transmission car. In Hummer, there are so many options for you to swift gears to gain the power needed for whatever the occasions it maybe, with the exception of street racing.

Ed,

I haven't cancelled the order yet! Sometimes I just have a hard time on purchases of items I just really don't NEED. What about you ...have you decided ?

RPV... Well I'll (almost) get there huh ??
Seriously though... I'll save that speed for my car.
