SP is for sale

Yes its a shocker and I am not keen to really let it go, but taking the future in consideration, I think this will be the best choice. Been offered a job outside of Malaysia and thinking of taking it up hence this decision. This is not an urgent or desperate sale. I am only going to let it go, if the price is right. SP is in immaculate condition, extremely low mileage and only driven in the dry. Total car mileage is less than 35,000 km and current engine has only done 3500km since rebuild. Super clean and super trick ride with a lot of spares thrown in. Got a set of wheels for track day too!! Here is the current mod list. If interested do give me a ring at 012-335 0607 or email mugil@troxmal.com.my. Serious buyer only, no scammers, no low ballers and no free test drive! Again due to the age of the car, registered 1999, no loan will be available. Would prefer an enthusiast to buy over and continue the development work!

Water Methanol Injecton

I have now been using water methanol injection for SP over the last one year and I must say I am enjoying it and glad that I decided to install it. There are many benefits of running water injection, and below is the explanation from Coolingmist themselves:

"Water injection, alcohol injection, water methanol injection or methanol injection are all the same thing. The only difference is the fluid you are injecting. Having a chemical intercooler or water injection, methanol injection or alcohol injection will cool the combustion temperature of your engine by cooling your charge. A super fine mist of methanol, water or alcohol combination will evaporate and soak up the heat. This cools your temperatures and raises the effective octane of your fuel. In most cases you will not need to run race fuel and pump gas will be fine. A water injection pump...methanol injection pump or alcohol injection pump is very important. The higher pressure your pump, the better that atomization will be in your water methanol injection system. "

As SP is running a very high compression ratio, it is necessary to find ways to minimize knock and increase ignition timing which are really the key to making power in NA engines. The results of water injection in a turbo charged engined is much greater than NA engines. Nevertheless, I am also interested in the other benefit of water injection, which is a much cleaner engine as well, as it also helps to steam clean the internals, especially those in the combustion chamber.

The kit that I am using is from Coolingmist who my bro Jack, has been using in his previous ride with good performance and reliability. The trunkmount kit comes with the standard 100PSI pump, 1 gallon water tank, piping, injector and mounting hardware. I opted to have the stainless steel braided lines and as well as ordered water injection controller called the Vari-Cool. This controller lets me vary the activation point and also a min and max setpoint, plus the allowance to control the amount of flow into the engine. This allows me to fine tune the water injection flow rate and also have a 50% flow during part throttle application if required. Currently for SP the activation is set using the TPS position. The TPS provides a 0-5v signal, which is then fed to the Vari-Cool controller, and from this we can set at which TPS position the water injection will activate. For example, at 50% TPS or less no water injection, from 50-80% TPS, injection at 50% of flow rate, and at 100%TPS full flow is provided.

This allows me to vary the usage of the water injection depending on how and where I am driving the car. I can also go one step higher by having this 3D mapped by my ECU like my fuel and ignition maps, but didnt want the added complications. I am currently using a 50/50 mix between water and methanol. Havent tried running full methanol although the system and engine is fully capable of this.

I have since changed to the larger pump by Coolingmist which produces 200-250 PSI pressure and also the Coolingmist Super Atomizing Injector for more flow and better atomisation. The higher the pressure, the finer the atomization of the water methanol mixture and provides more heat absorbing capacity. I have also added a LED on the dash to indicate when the pump is operating and this also provides indication if there is problem with the system. So far I am enjoying this mod and also have been stocking up on methanol :)

Enjoy the pictures.

Dyno chart and Header experiments!

Boy it has been quite a long time since my last post. Been quite busy with work and travels and also with my family. Not easy finding time nowadays!

Well first up would be my dyno chart, should have posted it up a long time ago but havent got the chance. This was done after I have changed to a full 2.5in exhaust setup with straight pipe and rear muffler from Tonnka. All of the work was carried out by the main man of Tonnka himself and I must give my hats off to their work and quality of stuff they manufacture!! Also running water/methanol injection during this run.

As you can see from the chart above, I am very very pleased with the results. My only gripe is to smoothen the mid range to remove the 'W' in the mid range. To date I have also experimented with a different header configuration (4-2-1), very long primary, tri-y design which was custom made by Tonnka. Although this improved the mid range by a whopping +16whp, I lost quite a bit on the top end about -10whp. So I went back to the previous header which is a 4-1 style from Formworks. I have a new header from Tonnka which I have yet to try, let see how much it helps.

Looks more like turbo header

Taken out after dyno- note color change after just 1 hour on the dyno

I have also got SP in the track at last and least to say I am still learning its new power delivery and also mastering all the gadgets on SP. Whats coming up, a revised brake setup and a new look! Watch this space!

Intake Setup

As you probably now know, SP has been running on the Jenvey Dynamics Individual Throttle Body (ITB) setup. Here is a breakdown of the bits that is required to complete the install.

1. Jenvey Dynamics Manifold to suit SF throttle bodies for Proton/Mitsubishi (part no: MPN01)

2. Jenvey Dynamics SF throttle bodies - 45mm tapered x 4 nos (part no: SF45)

3. Jenvey Dynamics Air horn (part no: AH45x60)

4. Jenvey Dynamics Fuel Rail (part no: SFR4/88)

5. Jenvey Dynamics Fuel Rail Mounting (part no: SFRC2)

6. Jenvey Dynamics Linkage Kit (part no: CLS1)

7. Jenvey Dynamics Linkage brackets and rod - SF (part no: LBF2)

8. ACT dry carbon airbox

9. Bosch 412cc Top Feed, High Impedence Injectors

10. TPS - Colvern CP17 - Motorsport spec (part no: TP1)

11. Phenolic gasket

12. Earls Swivelseal fittings and hose for fuel supply and return.

I actually bought three sets of airbox, one from Pipercross which comes with its own filtration system and also one from K&N (universal airbox), but both of them did not provide what I was looking for. But it helped to develop the current box in terms of available space and design. Luckily with parts bought from UK, if not used can be returned.

The JD throttle bodies are of a taper design, so at the throttle plate(butterfly) it is 45 mm and 48mm at the inlet of the body. This allows for high velocity through the port and promotes better combustion as well. The air horns were also changed due to its length, it was suggested to run longer horns but due to the space constraint I have gone for the 70mm long air horns instead of the 120mm ones. They also had a CF version of the air horns, but I was advised against it, as if there is crack or damage to the horns, it will be sucked into the engine and destroying it as well. So I decided to stick with the aluminium horns.

Fitting was not straightword unfortunately as SP cylinder head was massively ported and the inlet port of the head was a lot larger then the JD manifold. So we had to do a lot of customisation work to get this fitted and port matching to suit. I was really happy with the work done by GT Auto to ensure it was all done properly and professionally.

I will let the pictures speak for themselves

Harnessing SP

As SP is my dedicated track day machine, I have decided to invest in proper race harness. On one of my visit to the UK, I dropped by Demon Tweeks and bought 2 4 point FIA spec Sabelt harness. These are the 3 in wide shoulder and waist straps and with a n aircraft quick release buckle. They are also able to accommodate a crotch strap enabling them to be a 5 or 6 point harness. Being the weight conscious person that I am (on SP that is, I personally have been gaining the pounds), I decided to purchase the ultralight version (Demon Tweeks part no: 904570E) , which has the shoulder belt adjustment buckle in aluminium rather than steel. Unfortunately Demon Tweeks only carried one of these in stock and I had to settle for the lightweight version (Demon Tweeks part no : 904183E) for the passenger side.

These are fully FIA approved and are certified for use up to 2014. Unfortunately neither I nor SP will be participating in any FIA sanctioned event for now. Who knows what the future might hold! These harness comes with the eyebolts which bolts on directly to the existing seatbelt points in the car. For the rear as I have removed the rear seats, they bolt on directly to the rear seatbelt mounting points. They also make one version with roll bar attachment, which I didn’t opt for.

Some pictures of the harnesses and also the install picture just for the driver side currently.

Oh Boy!

SP has been running fine and I am struggling to find time to drive it. On one occassion after tuning, I took it to work and decided to see how fast can it go. So gently coaxed it on 5th gear to about 225 km/h and suddenly heard a noise, looked at the rear view mirror and the driver side roof weather strip got ripped out by the wind force. Darn it! Slowed down and maintained a steady 120 -130km/h and got to work. Called Proton to ask for replacement weather strip and was quote RM 544.00 per side! Oh boy, apparently its MMC item so thats why its a lot more expensive. So will only have time to collect the weather strip next week, meanwhile this is how SP looks currently.

Clips exposed, looks unsightly without the weather strip

Some of you may spot the new addition to SP as well. Will cover that on my next posting!

Dyno Chart

I have been fairly busy with work and travels and apologies for not updating the blog frequently. Below is the dyno curve from my last dyno session after running in the engine. As you can see the torque curve is a little wonky and there is a slight dip in torque and power around 5.5k rpm. This is the rpm that a lot of knocking is encountered, due to the engine characteristics, cam profile and also maybe due to the ITB length. The timing has been backed off a LOT at this area and my knock sensor still occassionaly triggers at this rpm on full throttle at high load or on a very hot day.

I have installed my larger 2.5 in exhaust which I will blog about another day, and this seems to have improved this which I am very happy about. I hope to have the water/methanol injection to come in around 5.5k rpm onwards to help with knocking issues and possibly run more timing.

Apologies for the quality of the dyno chart as this what happens when you have two young kids who get hold of your dyno sheet and decide to have some fun. Manage to stop those two rascals before it got shreded to hundreds of pieces.

2000km +

So it has been about 2000+ km and SP has been fully run-in and TUNED! With this new rebuild, power figures has went up and currently its making 191whp and 20kg of torque. This is quite an impressive power figure I must say, especially running just on Shell VPower and rather basic tuning on the dyno, we didnt even mess about with the cam timing for now. This was done without the water/methanol injection switched on, and I have a couple of things that I want to do before we activate it and redyno. I hope with all this in place and more time on the dyno, SP can churn closer to 200 whp or God willing surpass it. Remember its still very streetable, a lot more streetable then before! Some more pictures courtesy of a friend who visited us not too long ago.

Engine looks really nice from this shot!

Last but not least, the newly fitted seat, from a different angle

After 1100km....

Currently done about 1100km and engine is feeling looser....torque is very good at mid range, esp 3500 rpm onwards. Noise on full throttle is also quite menacing, but still needs a lot of tuning and setting up. Need to calibrate my knock sensor properly and activate the water injection. Water injection mapping will also take a lot of time, sigh, SP will need to have some proper work out session on dyno soon. Planning to get the ECU to activate the water injection based on 3D mapping ( load, tps and rpm input ) and to further fine tune max and min flow rate using the water injection controller fitted in the dash. Also need to fiddle around with the water/methanol ratio and may consider AV Gas for track days to reduce any chances of pre ignition (knock) and also to boost on the power figures. Lets see how it goes. Anyway heres some pictures of SP in its current state.

SP is back home!

Collected SP on Saturday from GT and to date have clocked about 450km, heck even took it to work today. Car feels good, accelerates well, and have the rev limiter set at about 5k rpm. Car behaves and drives very well, even at low rpms, totally different to the previous setup I had. On the dyno car made about 18kg of torque and 141 whp at 5k rpm with 14month old fuel and old plugs. This was obtained when we were doing the initial tuning for running in the car. Water injection also not activated, so its looking good, and I look forward to hit the 1000 km mark before we progress further. Pictures hopefully on the next update.
