MX5 SDV Power Upgrade Project

Recommended Posts

KugaWestie

I have now had the car for 12 months, and have spent some time exploring avenues to increase the power on my car.

 

I looked at Supercharging using an Eaton M45, as this is quite a common MX5 engine upgrade. The normal position for the M45 is on the hotside next to the head. Unfortunately fitting it on the Westfield in this position would mean a fairly large cut out in the bonnet and I did not want to do that. I think a Rotrex type charger would probably fit lower down where the power steering pump is normally housed, but they are eye wateringly expensive, so I ruled this out

 

I also considered turbo charging. This all seemed to be extremely tight in the engine bay with potential cooling/heat issues, and frankly I did not fancy it.

 

So the only other option is to stay NA, and try and squeeze more power out of the engine.

 

After several discussions with Northampton Motorsport and Blink Motorsport (both traders on here) I have decided to work with Blink to see where we can get the car to. Throttle bodies were considered, but have been put to one side at present.

 

So the plan is to do the following..............

 

Part One:-

  1. Drive the car up to Blink and do a power run, so we have a starting point.
  2. Whilst there, drop off a spare cylinder head that I have got complete with a spare set of camshafts.
  3. Come back home with a brand new PnP Megasquirt ECU and Innovate Wideband o2 Sensor.

Part Two:-

  1. Fit the PnP Megasquirt to the car along with the wideband, and run the car for a few weeks.
  2. Whilst running the car round with the new ECU on it, Blink will "Optimize" my spare head. http://www.blinkmotorsport.com/cylinderhead.html
  3. Spare cams will be sent off to Piper for re-profiling.

Part Three:-

  1. When the head is "Optimized" and the cams are ready, Blink will send these back to me.
  2. I will then fit the new head on the car, along with the new cams.
  3. Some help from Blink will be required to adjust the Megasquirt to allow for the new cams etc.
  4. I have ordered a new Westfield exhaust manifold to replace the standard Mazda manifold and S pipe, so when fitting the new head I will also fit the new manifold.

Part Four:-

  1. Once the head, cams and exhaust manifold are fitted, I will then drive the car back up to Blink for final mapping.

 

This will take a while for all the work to be done, but hopefully it will be well worth it.

 

I know if this proves to be a successful project, Blink will be very keen to offer this up as a group deal or similar if there is enough interest.

 

Power gains are pretty much unknown as this is an untrodden path for us with the 1.8 engine, but I am hoping to see a good increase.

 

I will do my best to keep this thread up to date with progress as we go.

Excellent - if my bonus comes in next month I'll be going the throttle body route without headwork so between us we should have some great data :d

 

Particularly if I can jump in on a group buy for head work later on ;)

Sounds good. Blink's results on track with multiple race winning cars proves their capability and depth of understanding of the Mazda and what it takes to make them fly!

 

(If you've not had it done, get them to give the geo a once over too, you'll love the results)

It is worth you having a chat with Blink before wading in for TB's  ???

I am not sure who is more excited - me or Blink!

 

I had a geo done at NMS last year

I did that last year. We came up with similar to you but with throttle bodies and the exhintake cam with adjustable pulleys. It sounds like further research has been done on that front but I'm sticking because throttle bodies is an 'intrigue' of mine if that makes sense. I've got the headwork down as 'stage two' of the plan.

Fair enough Dom  :t-up:

 

Like you say, we will be able to compare notes - that way you can decide if your stage two is worth doing, and I can decide if throttle bodies is worth it - win win  :laugh:

Firstly, we would like to thank Gary for choosing us to carry out the project on his car and we hope it is successful!

 

We are probably more excited than Gary at the moment as it is this sort of work that Richard and I love - it is the thrill of experimenting that makes you love tuning cars!

 

We have a wealth of knowledge in respect to the 1.6 MX5 engine but with regards to the 1.8 we have built relatively few in comparrison. We have used our experience from what we have seen from other customers cars to provide what we think will offer the best upgrade path in  terms of value for money.

 

As we develop this package with Gary we will keep the thread updated with exactly what we have done.

 

We look forward to starting!

 

........a little taster of things to come:

I'm looking good to seeing how this turns out :cool: and would be interested to know myself what difference the MS-PNP would make on my 1600? :)

There must surely be a few more horses come out Mark with the MS-PnP
