Hi all.

Good to be back on here again.

I have noticed more so in the last few months (maybe I'm going crazy) that when im in drive wheather it be sports shift or normal, that when im cruising on 60 kp/h and then floor it (foot to floor), it take at least 1.5 seconds to actually drop to a decent gear and take it, when it does its brutal.


Anyone know anything you can do to eleviate this problem.

I drive the VE Commodore as Police cars and they are pathetic with the lag when flooring literally feels like dough, and I'm disappointed that my car is now like this.

I have a Transgo shift kit in, wheather or not that is causing any problems I am unsure.

Love to hear your input all.

Thanks!

The RE5 box's downfall is the Transmission TCU, it is the reason the shifts take so long, not the actual gearbox. I just wish someone had cracked the TCU to speed the shifts up, or even replacing the TCU with a programmable unit would be great but nothing is available as yet.

The TCU adjusts line pressure based on pedal position, so if you floor it the gearbox will shift as hard as it can, this is much harder with the Transgo obviously. Did Craig do the install? What fluid did you use?

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

      Given you're running a 2.8 and my 2.5 is not really like for like, I suspect there could be a bit more timing you could give it. What is the kW yield per degree you're putting through it? Here's my E85 map to give you an idea, where it was I could still get another 3~4kW per degree thrown at it.

      Mistakes were made, my R34 Story

      It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.

      Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts.

      Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha

      Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
