Looking at one of my logs, 11psi was 180 load, so figure 170 - 190 is probably accurate.

 

Thats about right. 100 load is 0 boost at sea level. Then whatever your boost gauge read (11psi) x (7) + 100 at sea level brings you to 177. So yours is accurate.

 

im hitting 180-195 @ 0.8bar so i guess thats good then. Thanks!

 

Yes, the easiest way to figure out if its accurate is look at the barometric pressure on the logger when the ignition is on and the engine not running. On sealevel it would be close to 100. When I was in NV wich is high elevation its around 80. So you would take that reading and subtract it to your maximum load that you datalog then devided by 7 and it should give you the maximum boost in PSI that you logged. Mine was way off.

 

^ what causes this to be "way off"...

 

Don't know yet. I havent touch the car yet. But ill keep you guys updated. I might be able to do some troubleshooting tonight.

 

not to thread jack but i'm seeing 290-300 load at 22-23 psi on a 2.3/red/bf272. is this normal. my load scale only goes to 330. is there enough headroom for 30psi?

 

Not enough headroom. Doing a quick calc again with a MAT of 100F, I get a load for you about 318. So, your actual intake temps may be slightly higher than that or my calcs could be slightly off.

Anyway, your load will be about 20% higher going to 30 psi, so if you're at 300 now, you will most likely get to about 360 or so.

 

I put my stock uicp back and still logging at 340 load at 25psi so its not the pipings. Would this be the maf sensor problem? I couldnt' understand how it could change dramatically from just upgrading the pipings and the intercooler set up. I haven't tried boosting it down to 10psi yet. I'll try it out tomorrow again.

 

I am having the same issue with it reading at 270ish at 22psi and 300 at 25psi.

Anyone else have any ideas on this? This changed for me as soon as I did some breathing mods.

 

What's your new set up? We might have the same caused.
