done.. dw.. i installed it like in the pic. i also found a HKS T-piece off the fuel reg.. and a Greddy guage sender.. ok thats irrelevant.
Test Car.. 1990 BNR32 allmighty GTR.. Nismo exhaust, chipped ECU and steel wheeled turbos..
w/hole controller:
Upon first driving i noticed i ended up on boost reversing out of my driveway.. doesnt happen with nissan solenoid..
power is usable from around 2500rpm and full boost just shy of 3000rpm. and little lag between changes.. little lag at all.. its quite amazing. on the highway 100kph @ 2600rpm boost builds quite easially and fully ther at 3000rpm+.
it is set lower than what i was running prior to the test. 3psi or so lower but the torque is greater and all out car feels far more responsive and quicker than the stock solenoid.. (i am using the standard guage) noticed bleed off at around 5000rpm and it fluxuates as u rev on..
W/O the hole controller:
when i put it on the GTR it was set slightly lower on boost than the hole controller. initial response is good feels just as torquey as the holed controller. during up shifts the boost drops a bit more than the hole controller but not enough to whipe my smile.. unlike the holed controller ther is no spiking according to the gauge. boost is available from2500rpm upwards and full boost just shy of 3000rpm.
verdict:
I need another test car as the GTR doesnt seem to lag as much due to the TT set up. i will install these on the R34 and S14a and let you knw how it goes.
so far the holed controller seems to have a little bit more response but not enough to notice on the GTR, but sacrifices are made with spiking in the higher rpm band.
Both holed and non-holed controllers feel just as good as each other on the GTR but as i said the lag is not that noticable on the GTR. all up it is a massive and i mean MASSIVE improvement over the Nissan solenoid.
This is the best pic i could take while driving on boost lol.
can someone confirm how much PSI is going through her?
i will set them both to the same boost and install the same controllers on the R34 which is the lag kind..
stay tuned kids.
Mark.
