[sparks 0]

Hi people

 

i wonder if anyone can shed some light on this

in mfa speacial mode option 2 on pos 2

hg readouts flat out is 2nd i max 1860 yet near as damm it flat out in 3rd 1940

 

does it just give more boost due to more air rushing though the intercooler making it denser ?

 

also is 1860 ok for a stage 4 jabba sport charger on a 68 pulley ive done the searches and generally it seems abit low ?

 

im open for ideas!!

 

cheers stu

Mine used to see 1880 with a 65mm pulley on the mfa

i just though the read out was in hg the wiki site (buying a corrado made by corrado.net) lists it as low

 

thats why im wondering ??

just dug this out from the knowlegde data base

if mine making 1860 its just over a standard charger >>??

its got a standard head aswell so its not flowing more put reduce charge psi unless VW out of the kindness of there hearts flowed my head for free !!!!

 

 

 

USA EURO Hg(#'s of boost/vacuum) Comments

 

 

15 200 -23.7

55 400 -17.8

90 600 -11.9

127 800 -5.9

148 1000 0 (Atmosphere- ala no boost, charger is bypassed)

172 1200 2.9 psi (Your charger is dead or big boost leak)

192 1400 5.8 psi (Your charger is about dead or big boost leak)

211 1600 8.7 psi (Your charger needs new apex strips or big boost leak)

228 1800 11.6 psi (Great for stock pulley, Probably needs new apex strips if 68mm pulley)

242 2000 14.5 psi (Great for 68mm pulley on stock charger)

255 2200 17.4 psi (Great for 68mm pulley on heavily ported charger, hold on to your ass fast!!)

255 and up folks need to be careful with fueling, as the programming maps end at about 242 on the ecu. Dynotuning, and air/fuel/egt gauge, and custom chip recommended

you may have slight leak or do you have any flow work done? as i said, mine made 1880 with flowed everything, FMIC and 65mm pulley

they arent that accurate that seems fine 1940's good! if your that worried dont send it off for doing just get it looked at also how many miles has the charger done?

properly got about 20k ish left on it i was told it was rebuild by g-werks 10k ago so it should be fine

its runing a standard intercooler which i have heard is prone to leaking out the plastic bottoms

look like saving for a nice alloy fmic then
