wow that is a differnt looking HHR, glad to hear you got it runnig right.

 

Well I did have it running right. I swapped pulley's, then put a header on a couple of nights ago, so I'm back to the drawing board.
I posted over at HPT RED, I dunno if you have any input or not there?

HHR on baby moons? awesome. my pops has them on his pt cruiser. you've gotta be a baby boomer.
p.s. that front end is very well done. its got a nice classic look to it.(you custom fab that? or is it a kit one could buy?) i would look into some lowering springs soon, if it was me.. then the appearance would be complete.

 

Nope, I was just going for a 49 chevy look. I have a set of 17 inch wheels with P-Zeros for it too, these are my everyday burners though.

No, no map. I have the tMap ready to go, but I haven't had time to bring it down to my tuner to do it up. I don't want to mess with it, and for the time being it is running OK.

How does that GMPP intercooler work? I have the Cobra HE...but the intercooler?

 

It's just the upgrade for the intercooler (manifold end plate with additional port, and two flipped catridges).

I actually have the thick aluminum double pass heat exchanger, and with the combination of the intercooler upgrade, and heat exchanger, and larger surge tank I see very little IAT climb during boost.

Jim

 

i wonder if your low boost is related to the surge tank. the only other thing that i could imagine that is holding you down is the e-85 conversion, but i dont see why. what are your dyno numbers like?

 

i have the larger surge tank as well. you can bypass the bypass valve, and see if that changes your number.

 

I thought about that, but I've yet to try it to see. I think part of the low boost is just the 20% larger displacement of the engine and the fact that the blower is only so much CFM etc.

I may be on the dyno next week depending on how this E-85 thing pans out. We'll find out then.

Jim

 

he has a 2.4 silly so he was saying low boost in relative to him using a much bigger pulley

 

WTF!!!!!! another built up 2.4, where are you guys coming from????

pics!

 

Yeah forgot about the displacement factor. Have you dried porting the blower to see if it helps the airflow? I doubt it will help much if any at low rpms. Depending on how restrictive the blower is, there may be a gain to be had at higher rpms due to decreased resistance. Its prolly not as much as hoped though. With that E-85, you could easily go higher in boost without pistons, so long as the head bolts handle it. E-85 is 103 octane if i remember correctly. Which is why i want to go stage 3 turbo with the pistons... i may need internals and some other strengthing though from the increased power.

 

so do these electronic superchargers actually work.. ive never heard of em until now..

 

Yes! and also by putting acetone in your gas tank (10% mix) works wonders!!!!

















Please dont do either, I was being sarcastic. There is no way a PC fan can put out enough CFM's with out atleast a 1/2 hp electric motor.

 

heh alright

 

so it basically can work but our electrical systems cannot support the power it would take to spin the fan at a high enough rate to create a gain.

 

if you put in a larger alternator you could... 1hp is equal to 700 someodd watts of power. most efficent motors are around 80%. that is 840watts for the motor. Then when you pull it down to amps @ 13VDC that means the electric turbo will pull 65 amps/hour of power. Still sound appealing?
