Got a cl600 on an impulse buy. Looking to do before and after dyno. What should I expect? Car has about 70kmiles

From what I gathered the 600 is more like 520hp to 540hp at the crank stock, and with a flash (93 octane) should be a bit over 600hp at the crank.

I think it's like 20% loss threw the tranny so from 420hp to 480hp at wheels.

you can look for dyno charts on the web


here a nice writeup

Stock, you should see around 450whp on a Dynojet dyno. I have seen my buddy's go from there to 550whp with tune, intakes and highflow catted exhaust.

Kinda what I figured. My stage 1 tuned cl65 made 560rwhp. I don't think I will see more than 550rwhp after filters, cooling, exhaust and ecu/tcu. Was kinda wanting to build the 600 to be as fast as my 65. That car topped out at 670rwhp and do not think i will get to that without a 100 shot. I may just post this car up for sale.

My buddy's 600 was faster than my CL65 because it weighed 250lbs lighter....

My CL600 was right around 400 RWHP before the Renntech tune. After the tune, I was around 525 RWHP with stock everything else down to the paper filters.

125rwhp-wow, that's strong. Same dyno? 400 seems low stock

Yes, same dyno a week apart. I always dyno before and after any modifications.
