It won't be near 350 on a mustang my cobalt with cams full bolt on and e85 mad 340whp and 400ftlbs.
I'm trying to see what to do first zfr and set it at 325 till I get Boltons or go Boltons and then zfr. What I don't want is to spend 1200 on Boltons and end up making less than 300whp.

If you had a Colbalt? that's the big brother to the HHR same drive train basically. and it sounds like you already moded it up, So not clear
why you need our help? Sounds like maybe you could teach us a thing or two?

Lol the auto Trans just throws my figures off not sure the drivetrain loss difference. Soni was hoping for a dyno sheet to crunch some numbers.

IMO I think the 5 speed and auto with the same mods and tune, the auto is quicker in the 1/4

In the 1/4 yes the auto is quicker just because of how much smoother you can deliver the power out of the hole however, an auto will have more drive train loss thus should put out lower numbers how much lower I have no idea lol.

The gearing is different, and with a decent tune. You'll see similar numbers, lower, but hardly. Also 4th in the auto is shorter than 5th in the manual. You don't need tall gears down low because you won't be able to put that power down. And to the OP, get your bolt ons done on the stock tune. Then buy map sensors and a big turbo. Buy the bolt ons to prep for it, like the MAF relocate slot will come in handy later, but keep it blocked off until then. Wait for sales and keep an eye out for used parts. You'll save a fortune. Until you have that ready, look into different turbo options than a zfr. Yeah they're cool, but if you save money and do some research, I'm sure you could find a better turbo
