Thoughts on CLS55 vs BOSS302

Hey guys. A few weeks back I tried running a modified Boss 302 from about 45mph. It was close, but by about 125mph I'd say he had the lead, my front bumper was at his back bumper. I kind of expected to do better.

At that time, my car was stock, his car has a full exhaust, full suspension, air intake, tune, race wheels and is dyno'd at 434whp/382tq.

Since then I have installed a Eurocharged Supercharger Pulley and a Eurocharged tune.

Do you think me running him from 40, or 50 will be much different than the first experience?

Well kind of surprised from the results...he was out in front by about 3-4 cars from 40-120.

I've embarrassed a Boss 302 in my SL55 with EC tune, pulley and TCU

That's what I was expecting to see. Maybe something is wrong with my setup.

You should take him by 2 links now. You may want to add a belt wrap kit as well, so you do not loose power with the SC belt slip.

That's totally what I was expecting and I was just blown away by the results with him out in front by about 3-4 cars from 40-120. I'm just really surprised that his car seems so much faster than it should be stock, and he's barely done much to it (full exhaust, full suspension, air intake, tune, race wheels/drag radials).

Mine feels fast...but could something be wrong?
