We made the strut brace ourselves.

Do you have some idea how fast the air swirls as it passes through the restrictor?
Since air has mass, I'm thinking that if it swirls fast enough, can it form a void, or cavity in the center as it passes through the smallest part of the restrictor, in the same way that centrifugal force causes a void in the water as it swirls down the plug hole.
If this effect is even a remote possibility, then spinning up the air in the airbox before it enters the restrictor could only make this worse, particularly if it spins up fairly fast.
Just a thought.

Hey Dodgeman....Some guys have tried scribing "swirl's" in to the restrictors to get the air to spin, but it has not had any effect from all reports.

We have changed sooooo many bits on the car since the last time we ran it, so it's going to be hard to tell where the improvements (if any) come from. Since our last race meeting in September last year we have;

Rebuilt the head with new cams
Freshened up the bottom end
Added a crankcase breather
Removed the intercooler
Added a new gearbox
New Turbo
New Restrictor
New airBox
New air filter
New Front suspension
New brake caliper brackets
+ other small incidentals.

It's been a busy 5 months - I'm just hoping we get some good increases - both in power, engine response and handling.

Mark.

Mark, Can you please send me a seed from that money tree you have growing out the back.

I hope you do get some good improvements to reward all of your efforts.

I'm just about to join the poverty line! I can tell you it's been a hell of a stretch.

Ourplan this year is to compete in all 6 rounds of the state series, but there will be very little development money to throw at the car - so now it's a matter of tuning what we have to best effect for this year.

Fingers crossed we have made some good decisions.

i think if u want an improvement of airflow u should try one of the supercharger vortex things advertised for 69.95 ....

Know the feeling, have spent last the last three month doing mods to my Sunny to compete in all rounds of the QRC.
Lets hope the Sunny's make it to the end of season party!

they sell those vortex things over there too...

Why do people want to think that they actually make the car run better?

Got the air filter today to finish off the job.
