hi guys i want to go 12 psi ,but my tuner (evans-tuning) try everything and just don't see anything more than 8psi.. try to tighten the belt and all other place we can think of . but jesus wasn't standing on our side at all ...
plz help anyone


i got an DBW 2007 s2000 with the New v3 tuner kit, and here is all other mods..
Vortech V3 tuner kit with 3.8 Richard racing pulley and good year belt (4060495 (6PK1255) )

K-pro dual ecu
SOS 3bar map sensor
1000cc injectors
walbro fuel pump
T1R V3 70MM and 70MM test pipe.
all others are stock.
AEM Oil pressure gauge,AEM A/R Ratio gauge and AEM boost gauge..

 

forgot to mention the redline it is set at 8200rpm..

 

I assume no front mount intercooler? I would double check any couplers and make sure they are not torn or have a slit in them. Also and gaskets...say for maybe the BOV? I had a problem when I installed my TiAL BOV, the O-ring slipped out of place and left me with 2psi when I had a 5.7psi pulley on.

Also, I am not hating on your built or anything like that, but arnt 1000cc injectors a little overkill? 650s are the "standard". If anything the max I would have gone would have been 750cc's.

Either way, sounds like your headed for some SOLID numbers

 

Did you hear belt slip?

Someone recently mentioned that he uses 3M spray adhesive to fight belt slip.
He just has to reapply every 500 miles i believe.

 

well try everything, and no where is leaking.. as for the injectors ,because i am going 12psi, so my tuner recomand me the 1000cc ,as for me i don't know why i need 1000cc..
and i have aftercooled ..

but one thing , i didn't turn the belt adjustment bolt all the way in, because the belt feels so tight now, so do u know anything els that might helps?

 

i don't know.. but the belt is so tight , and he tuner said he doesn't know either...

 

uhhhhhh

isnt 380whp/240wtq a bit much for only 8psi?

kpro and the gauge reads 8psi?

 

yeah....

 

its def high, but its a higher then other reading dyno. i dont want to turn this into a hate on that dyno thread.

12psi shoulod put you around 400whp dynojet, so more like 425ish on that dyno. your def missing power, and its def because of the missing boost. evans knows how to tune.

did u buy the blower new? could be bad. aftercooled? maybe leak in that. do a leak test, i think they blow smoke into the intake and look for leaks. otherwise, i would think blower has problem.

good luck, that car is gonna move out when its running right

 

Evans said there is no place leaking, and everything it's brand new... after the tuned with 8psi since we can't go up, and we test drive it on some local and highways with him sitting down with the computer connect to the K-pro, he said everything it's fine...

1 thing i really don't know, hope u can tell me more about it..
the belt tension, do i have to go all the way deep in or just make sure the belt it's tight enough??


thx
