Nice!! Cheers for sharing :). More or less what one would expect, as you said.  A few hundred rpm laggier too by the looks?  And this would be on an RB30?

 

 

 

No problem.

Yeah I was hoping it wouldn't really loose anything down low but definitely did. However you wouldn't really know it to drive, and the plan was to try some E in it too. 

Yes, 25 headed 30.

Really really interesting how much... Or little difference the  a/r change made.  Is this a divided setup?  

And crikey - this looks like it's going to end up being a complete animal.

Yeah for sure. I started off with a .7 AR then .8x then 1 and came on earlier each time.

First time it has lost a little down low, but comes on hard!

Yes divided.

Nice, really interesting results overall.  What is the difference between the blue "E68" and the green "E68 boost earlier" curves?

655kw @ wheels isn't messing about at all, should be hell of a fast car there :)   The spool looks better than a few of the GTW results I've seen, quite cool to see a 25 head being used for something of this kind of power-  is it still VCT?

Blue had more WG duty from the start and really cold day.

Have not really seen any other results except I do have a GTW 3684 on a 25 I have graphs on.

Has everything there for VCT but not running currently, on my list.

 

Good power!  But yeah, solid point @Dose Pipe Sutututu - its what, 100kw at 4000rpm???  That is possibly the least power I've ever seen from an RB30DET at those rpm! :O

It's a dedicated drag car but running H-pattern for something a little different.

9.81 @ 142 with high 400s. New set-up should go a fair bit quicker.

 

More boost still to come. Plan is up to up it to around 40psi.

Not a DET [emoji6]

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
