Truck supercharger Followup + Dyno

shoeish · 10-06-2004, 10:12 AM

Well, after putting about 1000 miles on my truck with the supercharger installed, all I can say is *wow*. It completely transformed how the truck drives.

If you don't remember, its a 2003 chevy silverado 2500HD ls 4x4 crew cab with the 6.0, four speed automatic, and 4.10 rear end.

I put the kenne bell supercharger kit, found at http://kennebell.net/superchargers/g...0/gm48-60.htm, on a few weeks ago.

The kit includes

The results?
It comes off the line with unreal acceleration (for a 5700lb truck, anyway). Once past 50mph, it locks the torque converter in overdrive and *never* downshifts, even up 6-7% grades. Part throttle power is insane... you can squirt around people on the interstate with barely any throttle. You hear a bit of supercharger whine and you are gone.

In fact, a guy in a new ford power stroke diesel and I both noticed a guy going slow, and didn't want to be waiting on the other guy... I heard his turbo spool, as he began to pull away I noticed his a-pillar gauge pod (not stock?), then I put my foot down to the floorboard and left him. The look on his face was priceless. I *ripped* away from him.

Passing people... so insane. On a two lane highway, once the view opened up to where I could see for a ways, I passed four cars (in the same pass) that were driving about 60mph and being slow... when i got by the last one, I was going nearly 115mph.

I took the truck to the dyno... well, just to confirm that the a/f wasn't way off and to see how much power i'm actually making. My fears of a ping at 4900-5000rpm on a hottter day have been confirmed, I'm working with kenne bell right now to get it resolved. Here is the dyno, even with the truck pulling timing (because of knock).

Here is what the ecu was doing during the dyno run:

Sounds awesome...

/me taps foot wondering when DC is gonna finally release the HEMI supercharger.

What's the stock hp/torque and how's the gas mileage now?

Wow that's one nice upgrade.

Very very nice!

InfiniteNothing · 10-06-2004, 03:03 PM

That's a lot of torque. I love it.

Nice, tell us the results once you get the timing right.
