Very nice man, though I mentioned to you earlier moving the maf to blow through.
Can't wait to see that thing out in the spring, definitely gotta post some good vids

 

He moved it to draw through.

 

my bad, reading > me lol.
Still I had some serious issues using draw through on my car. odd

 

Thats AMAZING. Have fun with that bad boy. I will probly buy one some day.

 

Probably just different tuning methods, who knows

 

eh I tried a whole bunch of stuff. Everytime the BOV went off on shifts, it just dumped gas

 

During the tuning process, we learned that this installation is way different than our Cobalts in that the air piping runs are super-compact and short. He had only like 18" of tube from turbo outlet to intercooler inlet (to put the MAF in blow-thru), and like no tube at all from IC outlet to TB. Everywhere they tried the MAF was too turbulent in blow-through form, so they basically settled for draw-through.

Another really big factor is the car's light weight...it cannot establish as many different load conditions as a 3000-lb 'Balt. We see this phenom on the bikes too, but amplified even further. It leads to a vehicle that's more forgiving to tune, one more tolerant of draw-through.

 

ah well there ya go. I figured it could have been a piping issue.... but damn that some short runs of piping. I forgot how compact those things are.

 

wait for it.... wait for it..........and... yep, there it is... yeah, i have a boner.

 

It took you till page 9 to get one, man you need viagra

 

oh no.............he knows!

 

Thanks for the explanation. I was really surprised how easy it went once we moved it to draw-through since after reading here I figured we'd have a lot of problems. But

we had it tuned in 5 dyno runs basically unlike the 3-4 hours we spent before just to get it stable in blow through.

The car is a lot smoother, it doesn't dump any gas anywhere along the way. I could not be happier.

Bill, I'll send you the dyno graphs from the other guy if he hasn't sent them to you. Funny story is that he used my tune and even with his portfueler and 8 42 lbs injectors vs my 4 71 lbs injectors it worked almost perfectly for him. AFR's like 11 the whole time for him. Sometimes you get lucky.

 

Where did you get those seats?

 

On the atomclub forum in the for sale section. I bought them about 5 minutes after they were posted for sale. I'm going to repaint my BRG panels to the half black half red pattern of the Atom 500 and then put in the red and black seats

 

I saw those posted for sale and wondered who bought them. That paint scheme should look mighty nice!

I'm going to paint the tea tray,dash and nose of the CF Atom and add either red seats or do a bright red liner on the one piece seat. It just looks too...unfinished as is. Needs a turbo,too.I believe I'll let turboaddictionparts do one this winter. They seem quite eager to try one on an Atom.

 

can you post some exhaust vid's and flybys? that thing has got to be loud as ****.
