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.

      The Evolution Of "night Fury"

      By jez NF · Posted

      75% complete. Will now need to get a new axle with 5x114.3 hubs and then figure out how to customize some mudguards for it once the wheels are on.

      Trailer prep is underway... Lined up the wheel to get a rough indication of how it would sit Then removed all the bits (as far as possible) and gave the frame a light sand and quick lick of paint   Then added some carpet

      gauge needle removal

      By JC71 · Posted

      okay, so I figured this out, removed needles and reinstalled after swapping the gauge face on my triple gauge for my ER34, all work and look good. I tried to do the same for the main cluster, but the main cluster gauge faces are dished, the replacement gauge face are flat, so due to the dish in the org face ,mounting backing plate (clear) and depth of the needle, the flat gauge face will not work. I notice that R34 gtr gauges are flat, appears to be different clear backing plate that aren't dished. are these available, or what have others done to install flat gauge faces?

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Cheers mate. Seems some people get lucky others don't. It looks like the motor was detonating (to be expected if it was overboosting I suppose) as the pistons had a lot of detonation damage, and the bearings were stuffed. The bores were very scoured too, not sure if that's from the pistons or bits of ceramic turbo. By the by now. Have been trying to avoid the rabbit hole too much on the rebuild, and there's been a few hurdles along the way, but with any luck I'll have the car back soon™. Might even pop up a thread then.
