Good stuff. Its amazing how much room you have to play in with the battery out of the picture. All looks like a nice fit. Looking at it you probably haven't added that much extra induction piping even though it looks like it. I doubt a double pass FMIC would have much less of a pathway than the way you've done it. Boy its going to be loud through that K&N pod. Mine sounds like it has a BOV and whooshes even with a pissy little K03 so yours is going to make mums pull their kids away from the road side when you come past.

Haha! Yeah noise doesnt bother me, the exhaust was never overly quiet either Ill be making a heat shield/air directing plate at the front to section it off a little.

I was just thinking that the other day when I was finishing the pipe work. Overall it wouldn't be to far off the stock route pipe work but being that its now 2.5" pipes the volume of air would definitely be larger.

Looks like a candidate for adapting one of the Commodore over the radiator air inlet systems. K&N make a long skinny filter that sits along the top of most radiators.
You can make or buy the housing.

How are you planning to control airflow through the IC/radiator cores and into the pod? At speed, air is going to follow the path of least resistance which means it will go around the intercooler and radiator rather than through. There's a big gap across the top of the radiator, along with the sides. Having a low pressure behind the cores will aid airflow through.

Planning to use some black plastic board that we have at work to section off the sides and direct the flow onto the radiator and intercooler. Also going to make a heat shield/air directing box up where the pod sits to have as much fresh air going to that as possible. Being that there is no longer an A/C core, it gives there a little bit of a gap between the IC and radiator which should hopefully reduce heat transferring between the two as well as just give both cores more air being that there’s one less core to flow through

Pipe work back from being welded. Had some outlets welded on for the n75, DV etc. Now I can make the support bracket for the intake and start mapping out the head shield bracket I plan to make. I ordered the new MAF sensor I’ll be running which includes its own flange so once that arrives I’ll get that welded onto the intake as well and that along with the other IC pipe can be sent off to the powder coaters.

Injectors are the last main bit of hardware I need to buy before I can start plugging in the last few bits and pieces.

Physically a clever location for the blow off valve, but no so much technically. The ideal location is a close to the throttle body as possible, that way we are not reversing the airflow so much/so far. Having it close to the compressor outlet means the airflow between the BOV and the throttle body reverses direction when the throttle is closed. As a result the compressor has to again reverse the air flow (back to its normal direction) when the throttle is reopened. That creates a delay in the throttle response. Whereas there is no reversal of airflow with a BOV located close to the throttle body, the airflow remains in the right direction. As a result the compressor doesn't have to work as hard and the throttle response is faster. Probably not a big deal on a road car, but it is very noticeable on track car where on / off throttle response is important.

Cheers for the info Gary. I placed the n75, DV and other vac hoses to the same positions as where they run from factory and routing through pipe work the same way as well. It means one less thing to potentially cause issues/simplify the tuning side of things. It also means less pipe work running around the engine bay and makes it look a bit tidier. As you say if it wasn’t a street car, and purely track dedicated things like that would come into consideration as well as other things that can compromise drivability around town, but enhance performance on track.

While I await the powder coating to be completed so I can finish off pipe work, I spent today going to brissy, cutting out this shifter from the chassis through the passenger window because the door wouldn’t open (not that you would want to hop inside the car with another one stacked on top)[emoji28]

Then back home and swapped it out with the Diesel Geek slop removal bush kit installed. No factory bushes in the shifter assembly at all now and feels fantastic.

[louis19]

Last week I got my last lot of powder coating back so that all went back in right away so I could complete the plumbing side of things on the intake and surrounding hoses.

Got a few more bits to do this weekend, bleed the brakes and clutch, wire in the new maf sensor, fit the catch can and bolt the bumper back on.

The car has been booked in for next week to have a new dump pipe fabricated to suit this new setup. Once the car comes back from there it should just about be ready to crank over for the first time and with any luck I’ll be rolling around, running it in by Christmas.

Little things like a heat shield/air flow director to the pod still need to be made but that can be done once the car is going again.

good stuff Louis. Looks tidy as. What avenue are you going to take with the tuning of it?

Yoda-gavs ears are burning

Thanks Fellas. Yup Lee is onto it, it will be tuned via myself and Underground Performance (Gav and Alex).

Fingers crossed it’ll be running in on Xmas holidays, start tweaking in the new year

MAF-less? I'm picturing vids of it on the 2 step crackling out the tailpipe.

No it’s going to be running a special maf sensor. Stock maf will be maxed out and burn out in no time and I’m not a big fan of mafless setups in general. It’s called a PMAS HPX Maf sensor. Not cheap but rated to 600whp in a 3” housing. Can be used in housings all the way up to 5” (1100whp) depending on your engine size and application.
