hows it going people...

ok i have a set of 680cc injectors in as secondaries without anything to controll them for another week or two. On the dyno my A/F was at 11 till 4k then it crazy went off the bottom of the chart. hurting my hp numbers im sure. this was at 11psi.



I still have the stock top mount for about another month.

I plan on getting the realteck7 1.5 ecu chip and a fuel controller asap. im leaning towards the hks piggyback because it has more adjustments and moveable rpm points for under $200 new.

here is some info on it. HKS s-afr info

***ok with this setup... how much boost will be safe for the next few weeks till i can complete my project? the WG is ported massive for a s4 and the owner got it to run 6psi min with no controller.

from what i have read i think 9psi should be ok... i think....

Jaared

well i guess im just gonna run the boost as low as it will stay till i can get it on a dyno.

Jaared

well im going to go put it in... ill take some pics.

9psi it is.

Jaared

well its in... seems to be a tad more laggy... screams at 9psi. im wondering why im not getting full boost till 4.5k or so.

Damn, I wonder what my stage 4 is gonna do.. What exhaust are you running?

Jaared

3"hks dp that goes all the way back to the catback... its free flow... ill update more when i get more of a chance to drive it.

i have a 25 mile drive to work mostly freeway so ill see what it does and update asap. i will post my new dyno sheet as soon as i can dyno it. im trying to complete this and have it tuned before the 23rd... battle of the imports.

well my bov goes chipachpachipachi now when it blows off.

that means i need a bigger one right?

Bov isn't opening.
Stage 2? From who? Is it new or used? Lag might be associated with cracks in the turbine housing, it should not be that laggy....

Jaared

there were no cracks. ... and it is at 6psi by 3500or so and hits 9.5 at 4k. so full boost at 4k. i do have my twin scroll still hooked up. It was working fine with my stock turbo earlier today. made 5psi by 2.5k and full boost by 3.5k or so.

and the bov is opening... when i let off at like 6psi it sounds normal... when i rev it all the way it does the choppy madness. i have a feeling it dosent open enough, it says adjustable... would this fix it?

umm the turbo is a stock ht-18 and the stock compressor side has been opened up to fit a t04b wheel. the hot side is stock s4 A/R and wheel and all that.

The turbo is offerend at rotorsports. thats where it was origionally purchased from. the WG is ported as big as possible for a s4. without my mbc it went to 6psi. i then put my mbc on the new setup and adjusted it to ~9.

i mean full boost at ~4k is not that bad? right?

any ideas of what to check would help.

thanks

Jaared
