ZZP twincharged kit just got bumped up to 387whp/345wtq
wow, they just bumped the power up to 387whp/345wtq!
The twin charge kit comes with 2 boost controllers. One adjusts the boost from the blower and the other the boost from the turbo. This allows adjustment for how fast the boost comes in. As you can see from the dyno charts, our test car can put down 200WHP at 3k rpm with nearly zero delay time. Nothing else comes close to the low end grunt you can dial in with the ZZP twin charged kit! Our dyno mule never saw under 300ft/lbs of torque from the moment we hit it through the end of the pull.
We made 387WHP with stock timing, 11.9 AF ratio and 60# injectors which were close to maxed at that point. If you wanted to add timing or run leaner 400WHP could be had, which we consider the limit of the 60# injectors. We will have larger injectors available as well as full pump solutions that allow higher numbers. We did confirm that there was no supply issue with the stock pump and these HP levels.
The twin charged kit uses an air/air intercooler bringing the high PSI air to manageable temperature levels. From there and with the blower free spinning, the stock intercooler chills the air again allowing higher boost on pump gas than any kit on the market. Our Cobalt is stock with our twin charge kit and catback added. It's making 387WHP on a very conservative tune.

yea but on a stock car..i don't see how that much power doesn't blow a piston since most ppl mention anything in the 300whp range or more you need to worry..its great numbers..just wonder on how reliable this kit will be on stock internals

they worry because of tuning and the heat cause by the supercharger. Both of which kill pistons and such. Depending on how well the car is tuned, it shouldn't be a problem. i wouldn't expect the motor to last as long as a stock one though.

Well theres plenty of guys on stock bottom end that are running in the 330whp - 411whp range. Its all in the tune. The internals can handle the power.

Considering Stouffer's ZZP downpipe just took a ride on the failboat (blew apart at the flex pipe), im begining to question ZZP's product quality.........therefore a twin-charge kit from them just dosen't sit right in my stomache at the moment.
But still, impressive #'s for sure.

I still can't belive my eyes on the power they are getting out of this! It just blows my mind right now still. That torque curve or lack there of since it's pretty much a straight line is freaking awesome! I would love to see a datalog for the IAT2 temps though. I'm sure since they are low since they have a larger than stock size pulley on the supercharger that it isn't getting very hot at all considering the intercooled air from the turbo is chilled already that is feeding the supercharger which won't get too hot at all since it really isn't doing that much work, and finally all that air is getting recooled again right after. I'd be willing to be no prices have been released because they are daily driving it to prove it's reliabilty, so all the issues are worked out before hand. Quality looks good, and if they can make it reliable they will have a lot of sales here. I'll be keeping my eyes on this one to see how it pans out for sure.

This has always been something i wanted to do since i read about it back in early 06 when i bought my SS/SC. That torque curve is more like a torque line.. Nasty! I want to see that thing in action.
