Turbocharged SRT

[Cuda340]

In the March 2007 issue of Car and Driver, Hennessey Performance Engineering (Houston, TX) turbocharged an SRT 6.1 Jeep and got 620 hp.@6,000 rpm and 650 ft-lbs torque @4,400 rpm. He calls it the SRT 600. You can buy one for $76,440. SRT conversions make up 30% of his business.

The performance times are:

0-60...3.5 sec.
0-100...9.0 sec.
0-150...28.2 sec.
5-60...4.3 sec.
1/4 mile...12.2 sec.@116 mph.

Fuel economy....8 mpg.

His turbo packages are also available for the 5.7 Hemi. This engine will make 550 hp.

"The power comes from a Garrett turbo mounted UNDERNEATH the transmission- pushing 6 lbs. of boost, an air-to-air intercooler, and an upgraded fuel pump and pressure regulator. The rods and pistons are replaced, the engine is slightly bored out, adding 59cc, and the compression ratio is reduced from 10.3:1 to 9.5. Flow through the ported and polished cylinder heads increases by a claimed 20%. The factory computer is also reprogrammed to increase the fuel delivery and allow the throttle to open all the way."

He has added these packages to Jeeps and Chargers. Will the Challenger be next?

The article metioned he ruined the stock torque converter.

Didn't say anything about internet nut swingers though.

Your're right. He is offring a beefed up torque convertor for an additional $1,200.

With 620 hp, you wonder what else will break?
