If you don't believe me, do some driving in dusty conditions and the dismantle your intake after the filter.... you'll prolly see a nice layer of fine dust in there = NOT good for your engine.

You CAN get slightly higher ratio diffs. The diffs from auto ferozas were a slightly higher ratio, but they're usually pretty hard to come by...

Are there any alternatives that will prevent dust entering but still offer better performance?

The one I currently have now looks like the K&N filter:

What makes you thinkg that the pod filter is acutally getting more performance from your motor. For a standard motor, the panel filter is more than sufficient and much more effective than a pod.

- 7X15 wheels
- 30 X 9.5 X 15 tyres (low range 5th gear and 7000 RPM - 100km/h)
- 5cm body lift - home made
- 6cm liftkit - Trailmaster (one leaf for each side)
- 6cm lifted front with winded torsion bars, and cutted rubber on arms for 2cm.
- instead of EFI put dual weber carbs(40/40) - 9000rpm vith F300 engine wihout a problem.

Can a 50mm Body lift and 60mm suspension lift really be warranted for running 30" tyres? 60mm is a long way to wind up the bars and a lot of lost droop. I would've thought the Fez would get a bit tippy.

I can't see the stock motor getting to 9000rpm, 'without a problem', that's quite a big statement.

Holy crap, that's going to be super wide

stock motor with carburator and 9000rpm without a problem.
Here in europe is 50:50 carb and efi ferozas. carb has 63kW, efi has 70kW.

Oooo I love a big call on outers!

"no problems" at 9000RPM? did you have a wide band 02 sensor on the car to know that it wasn't massively lean?

I've seen sierra motors (also carby) at over that, but there's no way a stock carby will flow properly at those revs, let alone the cam gear. They don't feel or sound happy at those revs.

There's a reason that EFI motors have rev limiters on them - it's to stop this kind of sillyness.

I do not have o2 sensor, only original aisin carburator. The machine is HDC, not HDE like in feroza EFI.

My old Feroza handled big revs once. It was fine right up to the point that a con rod went through the side of the block.

Exactly - at 9000 rpm on a stock motor "no problems" is anything where the rods stay in the engine. Other than that you won't know, but that's about 3000rpm beyond what the carby and cam were designed for, and there's no way that that car isn't running dangerously lean.

Steve.

Even the Detomaso versions aren't rated betond 7500 and the limiter in the EFI cuts in then.

The Applause cams are a bit revier than a Feroza but not by much.

An HC is a short stroke version of the HD, deck height and crank are different but in all other respects the same.

Surprised the ignition works at 9000RPM....... like most small Jap modules it has its limits.

I will put this on video. Video is better than words. (tomorow)

The machine is:
HDC - 1600ccm 16V, 63kW
aisin carb 28/32
cam from applause Xi 4x4 (77kW)



EFI feroza 1.6 (HDE) limiter cuts at 6250RPM, charade 1.3 (HCE) has limit at 7500RPM (i own one of them - 1300ccm, 66kW and 4x4), but carb feroza HDC has no limit, and to 9000RPM works fine - but i do not drive it at this RPM.

Hope the video has sound - should be quite something to hear.

Can you hear lean?

Steve.

Sort of - you can hear all those minor mechanical bits getting unhappy at the same time

I wanna hear them valves tapping the pistons.. and each other too Ooohh the valve float will be ripe at 9 grand.

at 9k you should be able to see them come out and dance across the bonnet
