Hey all.

RB25 neo head, RB30 bottom end. Hypergear SS2 on 6boost high mount and 45mm turbosmart gate (7psi spring) venting to atmo. 3" staino exhaust with single muffler. Turbosmart Eboost Street Boost controller with 3 port solenoid.

Reading the turbosmart manual there is two ways to set up the boost controller. I am

Currently running method 1 and it is pretty lazy coming onto boost. Wondering if there would

Be any advantage trying out method 2 to see if can pick up a little bit better spool?

Will be going back to tuner with a little stiffer gate spring, dial the cams in for area under the curve and possibly change my boost controller config.

Cheers

Current config is 265kw at 10psi and 294 at 13.5psi.

I would ideally like to run make maybe 280ish kw low and 320-30 kw high boost. I think maybe 12-13psi low boost and maybe 16-18 high should get me in the ballpark.

As I don't want to run huge boost I don't want a gate spring that is too stiff, but that causes a little more lag. So I though maybe get a stiffer spring 12-13psi and then run more boost but the tuner can really relax the timing/fuel so it makes easy power while still coming onto boost quickly?

I would be happy to go to a 4 port solenoid if you think it will be advantageous.

I really don't know why people want two boost levels when you can regulate boost with your right foot... and I don't know abut "relaxing the timing" I always thought that you want as much advance as it takes to make it go best.

I have a boost controller that can have two set levels so may as well. And yeah I kinda f**ked up when I went 25/30. Didn't realise how much extra torque it would come with. At anything over 300kw it will absolutely destroy tyres and that's just a bill I can't afford. So trying to keep power pretty tame.

    • 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?
