I am but that's a good bit away from now. The mould for that will be a tricky one to make.
Madmac Motorsport's Twincharged Evo 5
During the winter build of the old Evo 5 hillclimb slag I decided to look at ways of reducing the turbo lag which was becoming an issue and costing precious hundredths of seconds on the hills last year. It never lacked top end power but the lag really started to get to me and i knew i could make it quicker point to point by reducing the lag - but keeping top end power.
I looked at many possible ways to do this but in the end settled for adding a supercharger to run in conjunction with the turbo.
Designed and built by myself with input from friends and members on MLR, most parts have been fabricated in my garage from whatever was lying around, the end result has been worth the blood, Sweat and tears I've put into this.
We've had her on the dyno at Wallace Performance in Aberdeen and had surprisingly few teething problems considering the unknowns and the huge amount of bespoke parts that needed to be designed, fabricated and made. Initial mapping is done now and the whole package is showing some serious potential! We've decided to keep the system at it's minimum until i do reliability tests and learn how to drive it properly :angel:
I've also designed and built a tubular front subframe and arms (total 9Kg
) to reduce front weight and while i was at it, it seemed rude not to play with the suspension geometry!
I want to thank a few people for their input and help:
Russ and the guys at Wallace Performance who did the mapping and supplied parts/tea/banter etc. Top guys and never ones to shy from a challenge! Can't thank you enough:smthumbup. http://www.wallaceperformance.co.uk/
My mate Steve Marr who is the main technical guru, and who i regularly bugged to ask lots of questions on a daily basis:smthumbup.
My mate Graeme Wight Jnr for his help with the front subframe and major suspension geometry changes, Exhaust and general setting up
Alan Young Engineering Ltd for the quality machined bespoke pulleys and parts, Spot-on parts and great prices http://www.timingbeltpulleys.co.uk/pages/home.php
And everyone else who suffered because of my constant lust for knowledge during the build:smthumbup
As yet i've to do some miles and get her setup for the start of the 2010 Scottish Sprint & Hillclimb Championship, so for the moment i'm being realistic about expectations & screwing the nut until i check everything over and get used to driving it. Hoping to do some track testing soon though. I've had her out for a short drive and so far the whole package is working impressively. Instant delivery at anything above 2500rpm with absolutely awesome accelleration in every gear! This is on it's lowest boost setting too....
Over the next few months The guys at Wallace Performance & I are going to refine some of the setup and see what she's really capable of! We know we can find a lot more power & torque with some simple changes.
Meantime i'm happy with the initial results and looking forward to Doune Hillclimb in 2 weeks Should be fun!
Keep watching....

The rear bumper came out of the mould okay. The mould was never intended to be put in the oven so a couple of small air pockets have left marks in the surface but they are only minor. This could have gone the other way and the mould could have been scrap but I couldn't know until i tried it at full temp in the oven.
On the scales it weighs only 4.5Kg, a wee bit heavier than i'd hoped but still 14.5kg lighter than the GRP one I've been using for the last 4 years.
I still have the 'fences' to make and all the fittings to setup which will add around another 1kg to this but still a worthwhile saving. it looks pretty nice in carbon too. This is straight out of the mould and the sharp edges trimmed off. I still need to tidy up and finish off the mould lines then give it a polish/wax which will bring out the colour and weave.
I'm toying with the idea of adding a wing profile into the fences as the airflow at this point is almost irrelevant to drag. I'll do my homework on this first though
Next step is the side pods

Looks great Donald!

Ok, so I get at least one email a week from other people who are building a twincharged motor asking for my help. Since I've spent hundreds of hours developing my system, trying new things and generally learning how it works, I cant just go giving out info such as pulley ratios, changeover valves and bypasses etc so is it too much to expect ( as a business) to charge a small fee for advice and help?
What is it with people, as soon as a fee is mentioned, and I'm talking about a small amount, I never hear back from them again?
To clarify this for anyone who needs advice, im happy to advise, help and generally spend time pointing you in the right direction, I will ask for a fee to cover.my time. Consider the cost of a destroyed engine, supercharger, turbo etc and compare it to the small cost of experienced advice. Its no skin off my nose if you dont want to pay for advice but please have the decency to say thanks for the initial free advice I always give on my first reply :shake:
Manners cost nothing. This applies to over 100 enquiries since this thread began .

LOL. what a ******... you're one of the most helpful people on the forum :shake:
I get a lot of PMs too on this and other Forums. I guess it can be seen as flattering that people will ask, and I always go out of my way to help people, but will certainly draw a line with the odd rude one (same one as Clive perhaps
).In your case Donald, you have developed a new and successful way of doing something and that has been a huge time and money investment, and is essentially something that someone can take and make money from. It's a bit different to someone asking what your alignment settings are or what size fuses you use.
I think any of us who have 'Project' threads have a degree of obligation to answer PM's about what we're doing / showing to a point, but I agree totally with you asking for compensation if they want technical information that has your blood sweat and tears on it mate :smthumbup
Clive, unfortunately it's the way it is with some people.
I've kept much of my build secret for a reason. If I just gave out info then i'd find myself in a situation where everyone would be building a Twincharger to rival Tiddles. Anyone with a decent grasp of mechanics will have worked out my system by now anyway. It's the finer details that make or break such a build that I get asked for direction on. This is the part that takes time, money and a lot of blind faith.
It certainly appears so far that I'm one of the few who have made this work, and work well, gone competing and been out in front of the rest for years. If everyone did it then i'd no doubt find myself being beaten regularly and TBH I don't have the funds to take her to the next stage to remain competitive. It was built, played with, fettled and now remains largely as she started because I wanted to use her and enjoy her. By asking a small fee for advice I can put that into the Tiddles development fund and try new ideas so in turn my advice would always be from experience. It's a circle, I do this and that, learn from it and then that advice can be relayed to anyone who wants to pay for my help.
There have been a few who have been more than willing to pay though so it's not all bad. The gentleman with the twincharged Lotus Elise benefitted from my advice, did what I suggested and his system went to the next level with one change to the exhaust system.
So, anyone reading who is building a Twincharger system and wants my advice, If you're not willing to pay then you can learn the hard way - as I did
. I have a business to run, time is moneyFatman100, I'll be doing most of the Scottish rounds this year, not sure if we'll be able to venture south as I've finally started to build the workshop extension and money will be incredibly tight through the year. A trip to Harewood may be on the cards but we'll be playing it by ear again.
At least most who follow this thread understand the situation. Most of my enquiries come from overseas, Australia, Singapore, Middle East, NZ, Japan, USA. Very few from the UK.
Thanks for your support guys. Keeps my faith in human nature alive :lol:
I'm afraid that is a sign of the times and i blame a good portion of this mentality on the forums. They are great for the social aspect but they are utterly terrible on occasions for people writing utter rubbish on a subject they know little to nothing about. People get used to receiving what they perceive as the answers to everything for nothing - regardless of whether the answers are right or wrong, its an answer!Ok, so I get at least one email a week from other people who are building a twincharged motor asking for my help.

As a tuning business i get bombarded with these pm's/emails/phone calls. You just have to write off a chunk of your working life to it because although many are time wasters, quite a few are genuine enquiries from decent folk. Nature of the beast. Spend 3 hours putting a big quote together with lots of detail as that is what they ask for and say ".... final price £5,500" only for them to never reply or to say "oh i thought it would be £500" :wallbang: A plumber wouldn't show up at your house for free and you can bet your ass most people wouldn't stop 2 hrs after work for free in their job each day!
What you can't do is give your technology away because be assured someone else will sell the ass out of it for nothing. Set your line in the sand and stick to it. Good luck and keep the faith Donald :smthumbup
Si,
At least we can share advice, compare notes and generally chat freely about our development work. We both gain from this because we've both been involved in similar development work
There's the thing, I'm happy to give out specific advice but before I can I need to know how the other system has or is to be built. This involves a few emails then I can give advice that will be relevant to that build but again, time is money and I aint giving it away for free.
To give this advice a figure, i say £100 per hour. Most times I could work out specifics within a few hours. A small price to pay if it saved £10k in failures.
It doesn't matter really if everyone builds a Twincharger, You all know myself and Simon Norris have been at the forefront of this technology for years. It's written in automotive history :lol: Well, on MLR anyway
Come round and polish TiddlesFully agree - btw how much do I owe you for reading today's posts on the thread?
don't know what you are all moaning about. I get paid for my services every weekend
But no one wants your advice :lol:don't know what you are all moaning about. I get paid for my services every weekend
