Looks like it’s coming along very nicely.
very nice mate Cheers.Hopefully all the hours will be worth it once it hits the road.
If I’m not wrong, when at speed the area under the wheel well is a low pressure area and not as good as you would think.
Also not that crash hot when it’s wet lol
So you removed the washer resevoir and put your filter down there?? Ive noticed alot of marks workshop do the same thing. Thinking about doing it myself??
That Whipple you have would benefit from a cooler intake temp.When i considered the Whipple before going the Vortech i thought my existing cold air box would have worked great and could have plumbed straight in.IAT’s were ambient when not in heavy traffic,checked off a lap top.Air was ducted from the front bumper vent hole to under side of pod and from above headlight,the top was rubber sealed to bonnet.Picture on page one.
The problem with having it down in the front guard is the risk of water soaking the filter when it rains.I will be making a guard at some stage to stop the spray off the front tyre.

What’s wrong with low pressure?A ram air set up would be ideal but impractical on a street car due to bonnet scoop or a forward facing opening.I thought a rear facing cowl like the one on your VR was to create a low pressure area forward of the windscreen so at speed induction is easier?
Spot on about the wet days.
Iv got my filter down there works fine
I have made up a gaurd to combat the rain and puddles even though it never seen the rain
will show some pics when I get back home
I had the tyre spray problem covered with a piece of 3mm plastic moulded to shape and bolted to the inner guard and bumper to stop the water spray and any crap flicking on the filter and I figured the passenger side opening in the group A bumper would help with the airflow, it was definitely no worse than having the intake under the bonnet where the stock vortech setup usually is

Cheers.Interested to see how you made your guard.
Maybe low pressure isn’t the technical term.
I remember when I drilled a hole in my guard and air box back in the day, fellow member Commodorenut told me it created turbulent air or what ever u want to call it. Which actually made the whole process worse.
At idle it was great, but once moving the centrifugal forces the rotating tire made was bad for it.
Ha ha. Just cut a whole in the bonnet and have the pods hanging out the corner that will solve problems. Ha ha. Joke.
Although could get rid of the headlight. I think im happy with mine at the moment though so yeah personal preference.

Got to be better drawing air from outside the engine bay.I had no other choice anyway with the way my set up was designed.
yeah but I’m sure if you had a guard or cover shrouding that area and had a pod filter in there kind of making that area a separate air box in it’s own right it wouldn’t be as much of a problem especially with an air pump either Whipple or vortech sucking the air in, I’m pretty confident that it would have to be more beneficial than detrimental

I’m hearing ya Cava.other forces at play can have an affect.Mine has to go in that position so i’ll make the best of it.
I was in the same boat with the vn it was either have it in the bay cluttering up space sucking in hot air or plumb it away nicely under the guard out in the fresh air, I have to say the car seemed a bit happier for it too

Yep that’s my thoughts.
A shroud wouldn’t hurt. + can help with keeping it safe from the elements.
I do understand what you’re saying to though cav, especially if you didn’t have the tyre shrouded it would make the air turbulent in that area which wouldn’t be much good at all for an air intake and especially not for a passive or natro intake but even on a forced air intake it would be better to have the shrouding to stop the centrifugal turbulence
Yeah I just bodgied this up out of fibre glass
I just st made it out of cardboard and sticky tape then glassed over it
about 2 hours later glass was strong enough to hold its shape but allowed me to remove cardboard then I had a skeleton out of fibreglass to work from, had to cut a big chunk out of side as I have pipe work there
also wacked a bolt through it all to hold air filter in place so it has 20-25mm clearance the whole way around it

vs manta 218.
Curious if that’d be restrictive with volume of air your engine would swallow?
I think if you boxed in that whole area like bottom of spoiler then from wheel liner all way across to chassis rail to make it like one large volumed airbox.
Less road heat & debris issue.
Impressive skills & car dude.
Yeah i thought about that
<span style=”line-height: 1.5;”> </span>
<span style=”line-height: 1.5;”>Personally i think the restrictive part would be the filter its self </span>
My plan is to make a bit of a funnel so it scoops a lot of air into them side parts
I wouldnt make a full air box down in there especially using the inside of bumpa as a side of it
Doin 250km/h backing off i think it would probley blow that side of front end off its mounts
I don’t think there’s any restriction with that shroud.Heaps of open area,it’ll just pull air from the area of least resistance.Nice air from bumper opening….might get a little wet if there’s rain on the highway.
Mine’s set up in different area and is close to the wheel at full lock because off adj radius rods.I reckon i’ll fabricate a partition between wheel well and bumper area to stop water and stones etc.
This hangs under the guard,attached to the blower intake.Should keep dry except for wheel run off,so need a cover also.
