Hey guys,

Ive just installed a blitz boost controller on my r34 gtt, it seems to be boosting fine, though the boost readings on the controller seems to be wrong when compared to the stock gauge the car comes with. The controller also isnt showing vacum it is always on 0 is this normal or should it be showing vacum?

I set the controller to kpg/c2 (or wat eva it is) like the gauge on the car, and the car gauge shows under 0 this boost controller is showing boost, you can hear the solenoid ticking so it is boosting while the gauge shows vacum. When the boost peaks the reading on the boost controller is slightly higher than what the stock gauge is showing.

Anyone got any ideas? do you think the t-piece for the boost reading is connected to the wrong hose? anyone know where it should be connected on a R34 GTT?

Thanx.

The factory gauge isn't really worth a pinch of sh1t to tell you the truth.

Never believe a factory gauge to be really accurate.

Mine isn't.

What about the boost controller not showing vacuum is that normal on a blitz boost controller?? It use to be hooked up to my old car but i cant remember if it showed vacuum.

I connected it to the t-piece on the hose that comes of the boost sensor in the engine bay.

I've a SBC-iD on a R34GTT and mine shows vacuum but only small numbers (-12 for example not -700mmhg like the stock gauge)

Hi,

Do you have a pic of your engine bay you can post up or email me? I wanna make sure i have the boost t-piece connected to the right hose on the engine bay, i think its on the wrong one.

    • A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.

    • I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.   
    • First thought is to use a ram mount (to hold the ipad) + windscreen suction mount. The arms on the ram mount can be as long as you like, should be able to position the ipad pretty well with that setup.
