Hoodedreeper's Mk1 The Purple Monster

[hoodedreeper]

Another little addition I've been working on are some LED under bonnet lights.

I originally fitted 2x 17cm White COB strips under the wings,which provided a lot of light to the sides but I needed something from above. Not wanting to cut too much into Garage Vary bonnet,i placed one below the catch. Feeding the wires through the two skins and out above the hinge. I then tucked the wires as best as I could behind the hinge,through underneath the scuttle panel and through the bulk head.

Here's a little video (taken on my phone) Remember to watch in HD

Gave the car a clean and went to a previous spot for some photos,here's my fav photo



Back in November i sent Adam @ RevLimiter a message about some custom dials. I knew what i wanted but it was difficult to transmit that pen and paper. Do i go something Grim Reaper related (to go with the username) or do i go with a Purple Monster theme? I couldnt find any images that helped or inspired,so one night i drew a design up in Photoshop. Not having done this before,it didnt turn out too bad,especially the colouring!

So i sent the logo over to Adam and he loved it! A few ideas were thrown back and forth and we finally settled for this design.



Here are some photos that Adam took,he seems to take them alot better lol



Adam has done an amazing job bringing out the detail in the logo



The purple diamonds is a nice reference to the Leather Retrim on the interior





Illumination was also a key factor. The purple numbers and white needles is a great combo IMO,i think being all purple would have been too much.

I wanted the logo to just illuminate on the Rev Gauge,and the text on the other. Again,Adam has done an amazing job!



The Monster had its yearly inspection this week and passed with flying colours! They were amazed and how much it had changed in the last year,and they especially loved the charger



I've been having this on-going issue with the door speaker cutting out. I replaced all the Phono leads,power cable and fuse box,swapped CD players and amplifer and still nothing. Tried an old set of Phono leads and it worked,so while it was all apart i re-located the CD Player (now a Mechless unit) to the Glove Box. Its freed up alot of space behind the dash,it still needs another tidy up but i'll be re-wiring the AEM gauges soon so that'll wait till then.



Last but not least,it was my Birthday last weekend so thought i'd treat the 'ol gal to a personalised number plate,EUNOS

​Just waiting for the transfer to be complete and i can get them fitted!

[hoodedreeper]

Today is 2 years since i took ownership of the car,what a crazy 2 years thats been!













Finally got my personal number plate transfered onto the car (i know the front plate is wonky,i need to adjust the bracket)



Last Sunday i attended the MX5 National Rally

Love this build!
Have you got any photos of the cd paid in the glove box?

[hoodedreeper]

I'm currently sorting that out. I (very badly) made a front cover/face for it. Originally i screwed the cage to the top of the glove box. This was fine until the volume knob kept hitting the centre dash bar on vibrations. Now made the cut out in the centre and its spot on.

On the NB glove box,theres a lip around the edge,so getting a 100% tight fit was difficult. With some skills it's probably do-able. I'll try and grab some photos

[hoodedreeper]

Updates seem to be few and far between at the moment. Last month i celebrated 5yrs with Ms. Reeper (not married,yet...) took her to a surprise few days away to London which soaked up alot of money

I've also been upgrading my photography equipment,again that hasn't been cheap either,but i've still been doing bits and pieces to the Monster

Shortly after the MX5 National Rally at Kelmarsh Hall was JAE at Newark Park. JAE is regarded as a the LARGEST japanese car show in the UK,and being a 4 day show,its a cracking weekend!

I won't bore you with photos,here's one from Heavy Set



Link to my photos can be seen here https://www.facebook.com/media/set/?set ... 756&type=3

Got myself another set of number plates,this time single line,which is alot better!



Practiced some light painting too,although it isn't perfect it didn't come out too bad



You may remember awhile back i relocated the Air Filter to behind the headlight. This gave great cold air to the filter,but the longer pipe work really made the car hesitate when pulling away and at lower revs. So i moved it back to the bulk head and quickly fabricated a heat shield that runs along side the charger



Received this month's issue of the MX5OC Hard Top Soft Top Magazine to find the Monster got a cheeky little write up



Ever since my track day back in March i've had the Sparco Sprint V bucket seat and OMP 4pt 3" webbing harness kicking about,so i slung it in the car for now along with my D1 snap off boss. Its weird how much a bucket seat and harness can drastically change the feel of the car,but now the wheel was faaar too close. Infact the bottom of the wheel was just brushing the tops of my legs.





So i ordered a NRG Slim Hub and promptly got it fitted

[speed]

Love this car!

I also thought to do the same with the heat shield but want to use 2 shields with a fire retardant insulation in between. So I'm still in the design stage.

How much of a temp difference do you think the heat shield has made once heated up and in stop start traffic?

Originally I had my filter close to where you do now but decided to add a pvc tube from the headlight area. So basically the opposite of what you have just done.

I've not experienced any hesitation issues down low and I've dríven it in 30 plus degrees heat. I also dont have a bag over the extractors like you have, so expect my engine bay to be hotter then yours.

My piping from the charger to intercooler is 2.5 inch though and not sure if that would change much, if anything at all.

Keep up the great work!

Jass Performance has just launched a new Upper Shift Boot,would be rude not to order one



Received another order from RevLimiter,this time retro inspired Horn Button and Oil Cap





The next installment is what i've been waiting to order for a long time,and i know it's going to have alot of mixed opinions

Garage Star Wing Stands with a Megan Racing Wing

The spoiler is just mocked up at the moment,need brackets making as the Wing is wider than the stands. Its on its highest mount point,i'll be bringing it down a little bit to make it more in line with the roof. I'll be making a diffuser while the bumper is off,makes sense as i've got the access at the moment.

I've also got a spare bumper to trial cut before i cut mine











Once the back is finished,i'll then start on the front

[rascal]

That's a 3D wing you have there which is designed to work below the roof line.

If mounting a wing that high (which is ideal to get clean air) then it really should be a 2D wing.
The 3D wings are much less efficient in clean air..

[bruce]

Yes, that wing wil divide opinions. There is a point you go too far with a car.

[hoodedreeper]

Rascal,if you read the post,i mentioned it'll be mounted lower and this is only a mock up

[rascal]

Hi HR,

Yes, I did read your post where you said you were bringing it down a little bit to make it more in line with the roof.

It still needs to be lower than that being a 3D wing.
The air coming over the roof is at a downward angle, compared to the clean air hitting it straight on, so you will still cop a drag and efficiency penalty by running the 3d wing that high.

[hoodedreeper]

So you suggest just below the roof line?

[Magpie]

I think that this is one of those modifications that will polarise people's opinions.

Having the rear mounts so far back will give more of a lever effect on the front, hence balancing the front aero will be difficult if using a large AOA on the rear wing. In a perfect world the wing should push down on as close as possible to the rear suspension to minimise the lever effect. Conversely the wing mounted so far back will allow a lower AOA and hence reduce drag.

What are your plans for the front of the car?

http://aprperformance.com/tech/
There is a popular notion that, in order for an airfoil to function on a race car, the airfoil needs to be in clean, free-air at or above the rear roofline of the car. This is only a partially-true statement. On cars with solid roofs and sloping rear windows, the air that flows from the rear center edge of the roof will travel downward at an angle toward the airfoil. The problem here is that only the center section of the 2D airfoil will see this downward "push" of air, while the outer section of the 2D airfoil will see much less of this (it will see straighter, freer air).

Decreasing the 2D airfoil's angle-of-attack to accommodate for the downward airflow causes the outer sections to produce relatively less downforce. Increasing the 2D airfoil's angle-of-attack causes the center section to produce relatively more downforce. The 2D airfoil ends up functioning inefficiently in this unbalanced state. This is a situation where the 3D airfoil has an advantage. The 3D airfoil's built-in angle-of-attack variations allow it to function more efficiently when it is mounted below the roofline. When the center section is mounted at 0 degrees angle-of-attack (relative to the ground), it acts as though it has a positive (typically 15 to 20 degrees in a sedan-type car) angle-of-attack relative to the airflow coming from the rear center edge of the roof. The outer sections, with the higher angle-of-attack built-in, are better-suited to take advantage of the cleaner, freer air stream. Therefore, the 3D airfoil, when used in a sedan-type car and mounted below the roofline, is able to function more efficiently (and in a more balanced state) than a 2D airfoil.
