So I've been looking for an hour and can not for the life of me find what kind of power auto hhr ss's with full bolt ons are making for whp. Anyone with some insight would be greatly appreciated.

 

figure on about 350hp IMO

 

Not mine, & E85 + bolt ons, I believe...

 

Need one of them with all bolt-ons and 91-93 octane to really get a good measure, right? I heard E-85 actually tanks the SS a bit...

 

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.

 

Factory "tune" they have on the Auto SS nerfs it bad from what I have read.

 

It does something fierce that's why I got hptuned.

 

Was that with a tune also or strictly bolts on?

 

I'd suggest since your HHR has a specific number of bolt ons , I'd find a local Dyno shop and run a few pulls to see what it really has!
No guess work, no estimation, and paper work to back up your HP and torque.

 

Currently I have no bolt on just the tune. I posted this hoping someone with Boltons could inform of there power level so I could decoded between full bolt on or a zfr.
