Hey, i just bought a 2005 crossfire limited and i have been reading about the tvt 250. Just wondering if there is a down side to adding this. Seems like there isnt upgrades besides adding chrome to the car, and im no fan of chrome. I've already added new intakes. Now im looking at the TVT 250+, and an exhaust system so any info on any of this would be great.

 

Speeding tickets!

 

iT HAS TO BE A BLAST.......!!! GO FOR IT!!!!

 

I have found no down side to the tvt 250. I have had the tune and injectors since the summer Carlisle show and an still pleased.

 

I'm waiting for the SUpercharger kit to come out, as it will make more power, and cost about a $1500 more than the 250hp kit. should make 300-310hp as this is what the NA motor has been dynoed at on low boost.

I know tvt has pushed the 3.2 up to 270hp from what I've read. but they spent a lot of money to get there.
to make 300 NA hp, after an ecu tune will cost you about $3500, maybe more, because the cams for the m112 are very pricey, and I've seen headers for this motor cost $2100. not too mention they are ver rare to find when available.

 

Where are the dyno sheets for the SC motor?

Headers are about 800-1000 for this motor and can usually be at your door in a week.

To get to 300 HP N/A figure on about 3800-4200 price tag. No head work or cams and full OEM reliability, not to mention better gas mileage.

 

I've seen several low boost dyno sheets for the m112 NA. you have to dig deep on the MBZ forums, check under clk320, and the German mbz forums, it's a b!tch cause you need a translator, but it's all out there..

there was a guy on ebay who sold his slk320 with a low boost conversion, he said it's a much more enjoyable car, so he went ahead and had them slide in the low compression pistons. He spent over $10k, but it was mostly laybor cost of a one off project car.

I believe Kleeman will e-mail you one of the lowboost dynos, but I prefer the forum for real world info without the sales pitch
