Cant find much info about EFR7163 on here.
So i decide to make a thread.

Currently my car set up is full build OS Giken RB31 with Naprec head build , upgrade fuel parts, with FullRace EFR7163, with PFC D jetro.
Yesterday is my car tuning day, When first 1.2 bar it just get around 640whp. until 1.6 bar it just 694whp. I am abit dissapointed with the results. We try to get more boost, but seems like the MAP Sensor cant handle more boost than 1.6 bar, need to switch to bigger map sensor maybe 3bar or 5bar. We guess 2bar which is max boost for this turbo.

My Question is, How many whp can this turbo get ? Its run with RON 97.
Starting my target is around 800whp - 850whp. But now seems like a bit hard, as reach 1.6bar still just 694whp. Fullrace did tell me this kits can make 800whp-850whp. But i dont know what is the problem cause. Fuel supply is still very enough.

Is my ECU Too old for this ?

Thanks Guys.

Your old ECU should be fine. You definitely need a better MAP sensor and after that your tuner should be able to spot any roadblocks. You say your fuel system is fine so have you got at least a 3.5in exhaust (4in better) and have you upgraded your ignition system? What is your engine revving to? Can you post up some dyno charts?

BTW 694 (is that 4 wheel hp?) is not too shabby.

Especially since a quick look online suggests they are only good for 550HP??!

OK the twin scroll 400 - 600 hp?!

Thanks for reply.

What else brand map sensor is available in market which is suitablr for pfc d jetro? Because i found the one apexi map sensor is 3bar. I have okada coil plasma for ignition, yes, 3.5 inch exhaust. 694whp is for twin 7163 on rear wheel. Yeah, i saw online the turbo is rated that. Thats why i am a bit dissapointed i cant get what i target. Lol...

      Yeah nice idea, you mean to suction it to the gauges? I hadn't thought of that.

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      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.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      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.
