Supercharging An Mx5 Engine

[Dave Ed]

It's an interesting article and highlights that it's not just about power gains but the whole package. Clutch, brakes and suspension set up are just as important.

Still loving Streamers updates. Wish I could fabricate like he does.

We've had a fantastic day at terry and Linda's today....tinkering in garage followed by bacon butties followed by a walk around the local fair.

 

The trial fit of the supercharger was successful thanks to everything being identical between the mock-up engine and Terry's actual engine.

Terry has a couple of radiator hoses that need relocating (nothing major) and a hole needs cutting in the bonnet which was expected.

 

The trial fitment today highlighted the bypass valve (yet to be fitted) needs a different location to the position I had in mind....so I'm glad we trailed it today before machining the outlet plenum!

 

Next job now is to machine the outlet plenum. It's going to be machined from a single piece of aluminium so should finish off the project nicely!

 

Here's a few photos from the trial fitment;

Don't forget our little idea for some CNC attention mate.

Really pleased with the fit. Dropped in place in less than 5 mins... Fits like a glove.

A few mods to Rich's original thoughts for the blow off valve, but nothing major.

Will definately need to make a larger cut out in the bonnet (where's Marcus lol). Hopefully keeping cut out within the bonnet side bulge profile...

This things going to fly.... Can't wait.

 

Cracking job Rich...

As ever top engineering !!!!! never any less from Rich mowerman

That supercharger is definitely going to need the attention of a Dremel, will you be ready for your Blyton session Terry?with regret I can't make it across on the 4th but good luck. Kevin

One thing I've been meaning to ask, I'm assuming this will be needing an aftermarket ECU?

[Tazzzzman1]

Yes, I'm going to fit the Canems ECU. Comes with a loom that plugs straight onto the MX5 loom, no messing with splicing into the loom.

Also upgrading the injectors. Using RX7 ones 440cc.

[Guest ali2992]

Ah OK, no extra sensors or anything needed? I'm putting in a MegaSquirt ECU and am looking to get a wideband sensor to help with tuning

[Tazzzzman1]

Nope, just nice and simple

The aluminium has arrived for the outlet plenum. The big lump is 5 1/2" square by 250mm long......I expect to be buried alive in swarf as most of it needs machining away!!!

 

Let the carving commence

Inches and millimetres in the same sentence!

Ya gotta love an Engineer!

Just like a chippy "a bit of 4"x 2" 2.6 meters long. Why not 8' ??
