how is this car modded ? the video even says that it's not installed yet

rory breaker

I thought the same thing but I think they meant the price was $8k or whatever, not including installation.

propain

You figure he should have smoked the CTSV with those mods.

BAD430BENZ

ok....but it also says that the car trapped 119mph

maybe i'm just confused or this info isn't correct

There is defenitley something wrong with this video. I dont know if its the mods listed arent correct, or the CTS-V is actually not stock, or simply Renntech mods suck.

A longtube header tuned C63 would completely rape a stock CTS-V.

I think stock CTS V puts out similar figures. Might even be torquey-er IIRC.

A bolton C63 will rape a stock Ctsv period. I even beat two of them just tuned.

Stage 2 back then was a tune and headers. That is what this car had. CTS-V was completely stock, but with a manual transmission which is rare. I can't imagine a tune only C63 beating a MANUAL transmission CTS-V that is properly driven. The CTS-V was also doing the no-lift-to-shift feature.

I think you mean manifolds. Headers are something completely different.

Jons95c36amg

The Ctsvs I beat were autos. How much faster are the manual Ctsv? BTW headers on a C63 you gain 3-4mph. Meaning I would trap 123+. A stock manual Ctsv wouldnt have a chance.

Your car must be a freak. This C63 trapped 119mph at the track the next day - maybe he didnt have a good tune. The CTS-V trapped 119.8mph on a lazy launch. I doubt it would trap any faster than that on a perfect run though.

Freak- I do pull on other tuned C63s.
