^ Thats what I thought too, though I was quickly corrected..

At what point did the dump pipe become a hold back? I didn't expect to hear that, it must have been a huge amount of power!

Not really Lith. seeing 3 lb of pressure in the dump at around 5000 rpm. Bit pissed off with my piper atm. when we had the 35r on the car he built a 4 inch dump. now we have the 37/88 he goes and shoves a 3&1/2 inch pipe on it.

I mentioned it to him at the time but he seemed to think it would'nt matter. WRONG!.

He's getting a visit this morning.

Oh! and for what its worth Lith it cranked out 530 hp @ 17 lb.

So the new dump pipe will be finished today? You gonna kick his arse for the stupid downgrade mate?

I would say no chance until at least next week mike. I will be voicing my displeasure. A day lost, 3 hours of dyno time, full tank of e85 all for no result. Not happy Jan,

Its funny. 18 months ago we would be cheering. 530 on 17 wow what a machiene!

Now its....... stupid engine...... only making homo mid 500's. on under 20 pound of boost. I mean really, why even bother.

Normally people start at 20 pound, not finish there.

Not really, 5 years ago we were making 520rwhp on 17psi using BP98 with T04Z's

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
