Is the MBC fitted in line with the N75?

Is the MBC fitted in line with the N75?

Not in line but parallel, just to cap the peak boost

[Chris.]

Got my yellows and 3" maf in today. 

All good, just a tiny bit hunting idle and we only talking a few rpm's but seems more noticable from the exhaust at the back.

Boosts to 20-21psi peak and occasionally holds the boost at 20psi for a few hundred rpm then holds well throughout the rev range, sometimes at 13-14psi at redline from a quick glance at the guage. 

HOWEVER...... there is a occasional/pretty often misfire at about 3250-3750rpm where the engine kind of splutters, not as if the wastegate is being pushed open, just what seems like a ignition issue, just like what it was doing on the denso ik22's but a bit less harsh. That is when the boost is at 20psi.  Anywhere after 4000rpm and theres no misfires. 

Was told it smells a bit rich, which is understandable, especially when booting it down the road.

Also feels like the power is a lot more at the top end of the rev range now.

Havent had any chance to do some logging, but inform me what blocks I need and will happily supply them.

Could the hunting be down to the ECU adapting to the new parts?

I'll put mine in soon so we'll have something to compare to

[Chris.]

I was putting it down to a slight over fuel in idle.  I've done a throttle align and cleared fd codes so ecu shouldn't have any issue really.

Not a Dub! But Awesome!!!!

When we first had this car in 2 years back it was kicking out around 300bhp limited by hardware issues, related to fuel flow and ignition coils.  A few live dyno/road mapping session ealry on this year gained around 340bhp, then over the last few weeks tuned to 440bhp limited again by fuel flow (crap complex nissan design)  So the 044 motorsport fuel pump was fitted.

Todays live mapping session (after spark plug issues) managed a peak power of 440bhp @1.3bar as a starting block, After many steady state live mapping sessions we worked our way upto 577bhp timing around 21deg and 1.6bar boost..  
 But not the right day to do the road test... had enough of watching my 6 year old son drifting/spining his Bambino race kart this morning and planted it in the tyre wall at 30mph, so dont fancy seeing 577bhp leave the road.


This is one of the 10 cars we are taking santa pod next week weekend..   Along with a 520bhp Astra Gte, Kadet 490bhp 11.4s 134mph, mk4 1.8T 410bhp, Mk1 1.8T 320bhp, my golf 370+bhp




First runs 440bhp

I've been out in my mates 450bhp R32 GTR which was mental enough, 577bhp must be unreal!

Dont know yet... far too wet up hear mate even to run it at .8 bar boost. Only safe place to unleash it all is at the Pod!!

they are a lot of car for not a lot of money nowadays.. i would have one in a shot if a insurance company would touch me 

[RTechUK]

No wonder I thought my car was off its tits when I removed the Bosch IKC knock control strategy from my map and wrote the timing maps from scratch using det cat to listen for audiable pinking......... The results speak for themselfs.
