I've presumably bought an SL65 from 2005. Just haven't seen it yet, other then on some pictures.
It's suppose to have a RENNtech stage installed that develops 707 HP...

But,
I've searched all over the web, and found 685 HP at the most.
The seller says, when I ask him, that there are documents to prove it.

Is the seller exaggerating, or have anyone else here heard of such stage from RENNtech..?


However, I'm not the guy to feel the difference of 22 HP. And that's not what I mean.
It's just that it troubles me, when someone is careless with facts/truths.
That of course makes me wonder, what else is then lied about..?!

Grateful for any thoughts.

Just a RENNtech ECU and transmission computer upgrade will give you 670hp@5500rpm and 840 ft/lbs torque@3500rpm. With the transmission upgrade, airbox and ECU its 685hp and 870 ft/lbs. The only other performance parts RENNTech offers for the SL65 is the Intercooler pump upgrade and RENNTech exhaust which could possibly bring the car up to 700hp but I doubt it, you'd have to contact RENNTech on that. I'd say its a slight exaggeration from the seller.

Sorry I dont think so. I am sure you have the 670hp or whatever RT claims. Its like the claim of the 722hp slr from them with just pulley and ecu. Just take it that you have more power then stock but with out a dyno you dont know how much. Congrats on the purchase and when you get the car just take it in and have it dynoed.

Maybe the previous owner had it dyno'd and thats how he came up with the 707.

Be happy if it makes 580 to the tire.
