Hello Andy

 

I see Captain Kirk has been active on the engine building sites of late which I follow closely myself. 

 

Are there more quest for power to come in the up coming posts? EWP, revised intake filter options....

 

Your regular post are dearly missed.

 

Stefan, If you're referring to the K20 site then yes I have and I also follow that lot closely. If you know that site and others you may know the name Jose Mercado, or Merc Racing?? I do a lot of 3D work for him, almost all of what you have seen from him in the last year or more has been through me. We have been working on an supercharged air to air intake manifold for the K20, for use with various superchargers. Unfortunately it wont fit in the mini so I wont get to use the fruits of my labour. I have designed multiple throttle body to supercharger inlets for him and a belt tensioner/extra idler pulley for greater belt wrap on the charger pulley. Here's a link to the site (http://mercracing.ne...ercharger-kits/) and a few renders of the work I did:

 

 

 

 

 

 

As for my quest for more power I don't have any firm plans or the cash to do so. Ultimately the plan is to swap out the M62 for a 2.3L Whipple Twin Screw, water to air intercooled, dual 60mm throttle body (like on the big block US stuff), remove engine coolant water pump and replace with electric pump to allow me to mount the SC low on the front of the motor, reducing the c of g. All in I reckon about £4k to upgrade, I might get some back if I sell my JRSC and I have a good source for parts from the US.

 

The only problem is if I do the above I'll never get started on my sprint mini so I am torn, I would love to build my own from scratch and have started on some modelling work but arent far enough to warrant starting anything yet, plus I am struggling for room in my current place.....

 

Those with a keen eye will be able to tell this space frame design is not to scale for a mini, it was a first pass at a spaceframe and I was using very rough dimensions. I have improved the design considerably since this attempt but gonna keep it under wraps for now. I have a rough Hayabusa engine model and My wheels, tyres and brakes are also modelled but there is so much more to do and not enough hours in the week.

Planned Upgrade of Exhaust System:

 

I am getting fed up with constantly being hassled at track days for being too noisy so I have hatched a plan. I am going to swap out the original 6" x 18" absorption silencer and the extra 5"x18" absorption silencer that I add for track days and replace them with 2x 2.5" inlet 6"x14" round Flowmaster DBX silencers from the US, two of these in series should remove a ton of noise and not be much more restrictive that the two straight throughs.

 

If you're interested in the information on the silencers here's a link: http://www.carid.com...technology.html

 

I have been static tested and drive by tested at Goodwood so I know where I am starting from, so will be able to report how well/or not they have been in reducing the noise.

[cptkirk]

So, the post above would have been true had there not have been a mix up with the labels on the packages sent from the US, so I found myself with less than a week to go to the track day and no frickin silencers.

 

I needed to hatch a plan to try and drop some decibels with what I currently have, plus a few cheap extras. I ended up using some 1.5" perforated tube and some 2.5" perforated discs welded into the tube and approx 45degs and at differing positions around the 360degs of the tube along the length. I have also had a bespoke end can made of which the top is enclosed and all gases are to pass through some 2.5" perforated tube onto the ground to help dissipate the sound (unfortunately I don't have a photo of the end can, will get one once its in place).

 

Here's a couple of snaps of the work, thanks to my mate Stevie G for doing the welding at short notice.....:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

it defo sounds quieter, the only problem is you can feel its getting choked at high revs........bummer.......

 

 

 

 

Fingers crossed for good weather on Monday at Goodwood, maybe see some of you there???

waw impressive read !

are you planning on doing a photo album with descriptions and details about the whole journey ?

I hadnt planned on doing a photo album with descriptions as thats pretty much what you've got here and that took me plenty long enough over the years...

LSMOC @ Goodwood 11th Aug 2014 - 98db static, 96db drive by.

 

Car feeling very choked due to extra silencer work as shown in my build diary, I was two's up with my good buddy Jim in the car and still managed only 0.7 slower than my fastest lap in May. Difference this time was that I took the time to sort my tyre pressures properly, hot = 22psi....first lap is a bit interesting as the nearside rear comes up to temperature but by the second lap you can get on it more.....

 

I only got black flagged once for noise and was hoofing most of the day, well, when it was dry anyway, there were some interesting moments in the wet morning sessions, coming round St Mary's, up the rise towards Lavant Corner to see a literal wall of water and the rain bouncing a good foot off the tarmac.....Oh Bejesus....

 

These videos are of the two fastest laps of the day, Lap 22 (video 031) was a 1:38:58, Lap 23 (video 032) was 1:38:67 (0.09 difference)

 

The Harry's Laptimer App on the phone seems to go awry at St. Mary's, going invest in a stand alone GPS for next time (Dual SkyPro XGPS160)

Some more footage from Goodwood 11 Aug 2014, this is from the GoPro, the session with the fastest laps. As you can see by the lack of sawing at the steering wheel the cars got a lot more to give in the corners. I think its more the fact that I put so much into it, not just financially but emotionally that is holding me back from driving it like I stole it......

 

The hand actions as I go round Fordwater were me saying how windy it was that I could feel the wind holding the car from pushing out on the corner at 100+ mph....

 

I just tried playing this back and for some reason it starts at the end, feck knows why......

A few slower laps - damned rain:

 

[Moggyton]

Its an atom!

[cptkirk]

getting drier:

 

[BronkoMini]

As long as your enjoying driving it there's no need to drive it to the limit and risk damaging it. Your still going really fast though, are you going to mini world action day?

I don't have any current plans to but might go, track time is not cheap though on a day like that.........

[BronkoMini]

Ah fair enough.

[BronkoMini]

Just read the whole thread again, as I have been looking for inspiration for what I should do to my mini, reading the bit where you said you've spent over £35,000 was an eye opener.
