I can promise you the computers in the HHR get in the way.

I have an evo 8 with 19,000 miles with 270 something HP, bone stock and it flies. Rain, shine, humid, cold, hot, it just runs the same and once on boost it explodes and goes. When I've time it it always runs in the 13's.

Now my HHR should be as fast and at times it is, sometimes it's not, sometimes it's just erratic.

The computer never gets out of the way of this car and with all the work, effort and time I've put into this thing I'm not dissing the car, just trying to understand it.

As far as the K+N fist day of dropping the filter on, it pulled 27 lbs and lit up the tires in second, did that a few more cycles, then back down to 22lbs.

Consequently I can take my evo to a mitsu dealer that has a specialty department and they will take it up to any HP I can write the check for . . . and to top it off they'll even add more drivetrain warranty to it.

If anyone knows of a place that can do that with the HHR SS and I'll ship it to them.

IMO

 

I've been to several dyno meets in different locations and I've yet to see someone not use a fan, this ranges from across Michigan, a few places in Ohio I've been, and down to Virginia Beach where I spent a couple years. For discussion this was also a Mustang dyno.

Honestly I'm pleased with my numbers, I wouldn't consider them "big", I feel it has more in it and that is awaiting Spring time and another retune which has been discussed with ZZP. The Cobalt's have pulled better on identical setups.

I'd rather lay down some times @ the track than throw out these numbers in all reality, but since they do their tuning on such I went for it. I've done a quite a few changes since my last 1/4 mile outing in October so I consider those numbers no longer valid but feel strongly about my goal this season .

 

But, I just don't like the fact that they have gotten all the way to the
selling point, with this product, without #'s to back it up. They know the #'s, they had it on a dyno, why won't they tell us ? If you go to their website,
& lookup air intakes, they tell you, & show you a dyno graph, for all their
other air intake products, but nothing when it comes to this one, why ?

i'm not ready to drink his 12 sec kool aid,but this is a valid point and it's what i'm waiting on. $280 is a nice price IF this works out well. however if i gain 5hp,then i'm gonna be pissed. i could careless if it made my engine bay look better(don't get me wrong,mighty fine looking mod)i want some good numbers and some function over vanity.

hey joe,down here in texas,if you dyno in the summer,you will need a fan lol.

 

ill have numbers soon....like it was stated, the intake tube gained 12 WHP, without the rest of the intake setup.... i have not dynoed with the whole intake setup, we had to take the car off the dyno to tune a customers car. im hoping to get it up there today.

 

thanks steve. don't take my comment in a negative light. just want to see numbers before i buy a part.

 

Umm both shops I use for dyno tuning use fans. Any proper run is going to use it
Hell for forced induction it's a necessary requirement people


The kn gain is almost all from their turbo to intake box upgrade, stock one pancakes badly! That is why you could mod zzp tube and get same results
This setup may show a large gain or a smaller gain. But it's other charts interest me the ability to fully correct air fuel trim etc

 

definitely a requirement! NOT using a fan would be like putting a piece of cardboard over your IC when you go to the drag strip....doesnt make any sense :)

 

i'm sure crazy steve did or could have easily gotten into the 12's. in 09 he was running 13.1's...so someone going into the 12's isn't hard for me to believe...what is hard for me(maybe others)is the way you are claiming you have done it. then as it comes out,you have added things little by little to your story. you came on here making it seem like you did it with little modification on street tires. then you say well it was on drag radials with 15inch rims. then it being an automatic really makes it hard to believe. now i don't buy into once your auto is tuned you get the same hp as a 5 speed. auto 235,5 speed was rated @ 260. so,if an auto and 5 speed have the same tune and everything else is equal and say the tune gave 50hp. so basic math is 235+50=285 260+50 is 310. now, you talk about cams and what not. i will be honest,i don't know much about that,but there are others on here that do and they will call BS on you if that's not valid. i do believe12's are possible and easy to obtain,but not through the route you are saying. i think a gutted panel 5 speed with my mods,a little more aggresive tune,fully tuned suspension,mounts and drag radials should get a 12.5-12.8. crazy steve proved with basic bolt on's(no intake) stock turbo,13.1 can be reached on a full interior car. so,do the math...

 

Oh I am sure a fan is needed in Texas, just for the people in the dyno bay alone!


How dare you think you're the only one here whom could run 12's, only one whom has, maybe? The only one with the goals, certainly not . Sadly I've only owned my HHR for 7 months now after trading in my Cobalt SS/SC for a clean completely stock HHR I seeked out with the G85.

With the Trifecta budget tune and downpipe alone-


60' times are horrible, thanks to the 5psi 1st gear boost limitation and my inability to get a response from Vince to cure such. I'd like to given his budget tune more justice, but he just didn't care apparently.

So 13 second barrier, easily broken with minimal mods on factory Michelin's and stock clutch, full street trim in October 2010, won't even take me a year so no worries here, track opens in April . Fun fact: I bought my HHR on a Friday across the state, drove 2.5 hours back home, then 1.5 to the track and raced it that night. 15.0's all night , weak!

For reference I am not proud of those times at all, but showing it's easily done and more time behind the wheel and the new setup, I am pretty certain I can meet my personal goals.

 

With the auto you get consistency, but you also suffer the drivetrain loss, personally to each their own, no care there .

I'm going with this.

ZZP intake to remove the intake restriction.
Catless downpipe to remove the exhaust restriction.
Front trans mount to make it stick.
A E85 tune.
