Got the dyno results, pretty pleased but i think there is a little more in it.

The differance is GREAT though.

Here are the B4 and after graphs.

B4 (red) = Previous exhaust and K&N pod

After (blue) = New exhaust and BMC pod

Power: (Average of about 20-30rwkw gain throughout the mid range)

Torque: (Over 1000N of tractive torque gained at 122km/h >_< )

Need a new boost controller as the factory solinoid is unable to keep the boost steady with the wolf controlling it :) . So once this is done, i will get a final tune. Boost drops to about 16psi at peak, but is a little wavey all the way through.

Thanks guys!

Picked it up today and boy did i enjoy it :dry:

The delivery is very smooth, but sharp/fast. Definately noticed the differance in 2nd, 3rd, and 4th, the rev limiter just comes on so quickly :D , can't wait for DECA and the coming cruises.

SS8 Gohan: I truely beleive at least 90% of the gain is from the exhaust, but i have seen other cars just change pods to BMC and gained about 3-5rwkw across the curve. BMC filters are top quality and aren't cheap, apparently they are used in the F1 cars, they have great flow and filter very well.

Jetdat: Very interesting!

As you know i am using the smaller brother (gtrs) so that would probably explain the steep curve. But i also have tomei poncams and head porting, which is probably why i am making the same power and more usable power; as the power is bought on earlier and is held longer. Not sure how much boost you are running but mine peaks at 18.5psi, then tappers down to 16psi buy the time it makes peak power.

yeah i think the cams make a difference but smaller turbo also gives the curve some steepness..

cams are next on my list so hope to get improvement once installed..

look forward to some 1/4 mile times from yours and mine.. :D

BNC filter setup it awsome.

Its a sealed unit...flow really well and allow you to duct straight from the front bar...

Al who did u get it from, I spoke tot the BMC dist. not long back...he had to order it in and I never called him back. PM the details man...or talk to you at DECA.

Cheers.

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
