Ram Induction on my T51 via Scoot bonnet.

[Warthog]

This is still in the R&D stage but it works. So fabrication will be the next stage during the winter months. It is one of the reasons I got the Scoot bonnet so that I could use the air tunnel to give a cold air feed to the Turbo. Anyway comments please. It\'s a simple idea and they are the best!!!

[Crazy Eddie]

Fair play that looks good and the heat sheild seems like a good idea too.:Thumbs-up
My only concern would be rain water running striagt into my air intake. Would this cause a problem?
Keep it posted though really interesting.

Ref the rain, it will drain out if any collects in the bucket. The bucket is there to cause a vortex as the air is forced into the scoop. We have blocked off the tunnel and diverted the air down.

John, I\'m no pro, but that looks restrictive to me.

Not enough air going to get through that small opening in the bonnet.

It\'s been put together by the lads at the RX-8 team and it\'s a design thats tried and tested on other race cars of different makes and types.The opening is large.

ahhhh somewhere to cool my bottle of Champagne

looks good John, will you be replacing the flexiable hose with ali tubing?

[Red and Single]

Like I said .... not a pro !!

Good luck with it, do they know just how much air that thing sucks at 2Bar :chat

[Bobbit]

i like the look of that, as you said simple! Nice one

[A7NTY]

Nice one Hog! Nice use of the bonnet. Remember the problem with metals, some more than others is that they absorb heat, so you may be better off with a plastic heat shield.

Cheers, Ant.

BB-- yes mate, as I said only in the R&D stage at the moment.
Gave her a short run last night and she felt more reponsive as cold air and not heatsoaked engine compartment air. I am going to give it a good blast tonight as I need some more V-Power go go stuff.
I will know a lot more on tuesday as I am down at RE:WORX having the Motec etc fitted and tuned on the rolling road, so GEFF & MAX will be able to pass comments etc. I have plenty of room in the engine bay to make any alterations to the system, but for now I will just have to see how it goes. We are going to put temp pads in the bucket area to see how cold the air is, but after the Motec is done.

Ant-- it\'s all made of plastic at the moment except the air-filter. The bucket is just that a plastic bucket with ali tape on it.

Bobbit-- Over the years I\'ve looked at all kinds of ideas and Ram-Air projects for the RX-7 from all over the Web, but they all involve a lot of complicated work or are a token add on bit that does not get air directly into the turbo. This is simple. The air is rammed in and the turbo can suck as much as it wants. Anyway time will tell.

Right then---Test run done.

Went off to Shell garage with next to no fuel so only had a little play just before I got there to make sure intake tems would heat soak when sat at the garage.
Started her up Water temps 85 intake 50 on the pfc.
Drove 2 miles down the road at 70mph, knowing I was going to hit a traffic jam ( part of the plan ) intake temps dropped 11 degs, then sat in traffic for 20mins until I cleared the roundabout to open road. The temps did not move up or down. Well to say at that point I was happy is an understatement.
Open road, with traffic so doing overtakes, full boost setting so 400 ponies at the rear wheels @ 0.95 bar boost. The intake temps came down even more as the cold air rushed into the turbo, down to 31.
I then tried it by staying in 3rd gear at 5000revs just blasting overtakes by blipping the right foot, only went up 3 degs and back down to 31.
Came off main road onto back roads to my home and played a bit then pottered along in correct gears til I got home. Air temp 29 degs, water 80 degs.
Based on that I\'m over the moon so far. What do you all think?
 Comments welcome.:Typing

[gmogle]

Yeah very good mate,

Water Injection will bring it down even more !!!

[Warthog]

I run that as well, but only after 0.8bar.:Thumbs-up
