FM Westfield racing and modifications

We have the AIM dash and aeroscreen back in place on the car.

It's slipping back into full race mode.

The aftermath of a bunch of turbo plumbing experimentation.

One of the few modifications required to a stock part to fit the turbo.

The water pump inlet is a little different on a Mazdaspeed, so we cut and welded ours to suit.

The intake sure gets some cold air - it's placed right behind one of the nostrils.

Bill stuck the intercooler in the car before we took any pictures of it, but it's mounted to some new bosses we welded to the rad.

It's relatively small, but between the huge amounts of airflow available and the water injection it's big enough. When we datalogged a full boost run, we saw intake air temperatures that were 4 degrees C above ambient - and dropping under boost!

Turbo system, version 1.1.

First, we took the car to our local track and completely demolished the track record with it. Keith's track record. The plumbing has been cleaned up, and you can see the intake pipes run forward to an intercooler mounted up front. The water/methanol injection is still in place, but we're using a more subtle white hose instead of red. The car is a monster right now, huge power but very controllable.

At the track with the new turbo system.

We added water injection to keep the intake temperatures down - you can see the red feed line running to the intake. We realized that we could have made the turbo system almost invisible as it would have been easy to run the piping underneath our heat shield. How did it work? Very well. We're still tuning it, but it was the fastest thing at the track yesterday.

The new turbo exhaust is fairly basic.

A 2.5 Magnaflow muffler (the same one Keith uses on his Seven) and a fabricated downpipe. The exhaust is joined to the downpipe with a V-band fitting so it's quick and easy to remove.

The car is up and running, although it's still an experimental setup and looks a bit rough.

Bill's going to plumb in water injection to avoid the difficulties of fitting an intercooler, although there is room in the car. Oh, and it's going to be on track tomorrow morning. We don't waste time before testing around here.

The Mazdaspeed turbo packages very nicely in the Westfield.

There are a couple of small alterations to the Mazdaspeed engine that we had to duplicate, such as a reconfigured water pump inlet. Still, it was a pretty easy job. We haven't seen any aftermarket forced induction systems that would fit this well - yet.

The turbo system from a 2004-05 Mazdaspeed MX-5 should fit in the Westfield frame.

Over the course of testing, we had an intake manifold stud break off in the head.

Luckily, it's an easy fix thanks to the accessibility of the engine in the Westfield.

We're using our car for cam testing.

We've tried a few different options, but none are performing to expectations. Well, not yet anyhow...

Mike Miller's completed car, in the pits at Willow Springs.

We like his modified windshield. It's got a cool hot rod look.

We're not driving the only Miata-powered Westfield in the US!

Here's Doug Beckett exercising his at VIR.

A custom roof for the Westfield!

This is mostly for shade - the sun's pretty brutal around here.

Bill, in the Westfield, and Keith, in his Seven, battled all day for the fastest time.

They were 0.2 seconds apart and grinning like idiots.

More track time, this time at the Flyin' Miata Open House.

Since we were giving rides to people on the road, we reinstalled the windshield.

We've installed a AIM datalogger as well.

More information on this little toy is coming, but it's very cool and can interface with the Hydra engine management. This was mounted to a flat piece of aluminum for a dashboard.

The aeroscreen is a bit more than just a black shield.

There's a lot of sculpting. The little kickers on top are smoked plastic and can be removed. There's a surprising weight loss with the new setup - the windshield is heavy!
