Re: Shock absorber boots

There's very little point applying grease to the damper rods, the wiper seal will scrape it off anyway, dirt will stick to it, and all you'll do is basically stick what is now grinding paste right against the shaft and seal. Give them a wipe with some WD or a light oil if you must but otherwise leav...

Re: Choosing new HT leads

Fit the Magnecors, mine were on the car for years and that included a lot of wading through streams, puddles, mud, sand, etc, etc, and the leads never missed a beat.

Re: Coil pack testing

The Magnecore rely on their spiral wound metal core for noise suppression rather than the track resistance in the carbon type, so you can have them pretty long and still be similar resistance - especially with KV85/100's - but to be honest resistance isn't really much of an issue in the lead unless ...

Re: Watch out. The American is confused by European gas, and he has questions...

Never made any difference when we dyno tested it, as already stated, the '8 isn't limited by fuel knock for it's ignition timing anyway. Adding more timing with higher octane fuel gives you nothing but more risk.

Re: Brake force comparison

What Pete said, all a brake roller tests is that you can lock up the tyre with the brakes. It doesn't matter if it takes 3 inches of pedal travel and 100lb of force to do it or half an inch and a feather.

Re: Opinions on Dry Sump Pricing

"Winging it" sounds a bit like a bodge job, but I assume you mean adding side pods (aka wings) to regain the capacity lost in rebating the area for rack clearance. Yes, common thing with race sumps where you can't/don't have a dry sump setup. We used to do it with VQ35's as there was no point to a ...

Could you not just have modded the original sump and then winged it to get the capacity back?

Re: Coil pack testing

As above, you can't sustain full dwell up to the redline because you simply don't have the time available. Having said that you don't necessarily need it as combustion pressure is dropping too.

Re: Electric SUPERCHARGER

Probably ~30cfm with little/no restriction. And then zero at ~0.05psi - just going off my EBM catalogue.
It's probably not even going to have enough flow to stop it from restricting the intake at full throttle.

Re: The importance of a good ignition system

Yeah, the stock leads are crap, the insulation gets compromised really fast with heat/ozone, etc, and then it arcs up the sheathing to earth instead of the plug, I don't think I ever managed more than a single weekend on stock leads before they were arcing up the insulation.

Re: RRP r3 - s1 water pump

I used to fit them to the S1 engines, they had far less cavitation over 6krpm than the S1 pumps did, much better when they're not pumping vacuum pockets at high rpm. Mind the larger/later pulley helps some with that too.

Re: How to improve Ignition

It's easy, a normal piston engine is going to fire it's coil at half the crank rpms, the rotary fires every rpm. So 9000rpm 4-stroke piston = 4500 sparks/min/coil - for a rotary that's 9000 sparks/min/coil. Basically more like a 2-stroke ignition system (in fact the easiest way to fit an aftermarket...

Either both together, or the inside, outside, then inside again is the quickest way to purge them.

Re: Uprated engine mounts?

When I started playing with PU filled OEM mounts I found that to have them soft enough not to buzz the car meant that the suspended drive train would resonate (wobble) over bumps. It was only a very subtle bouncing but I could feel it and knew what it was straight away. And it annoyed me. After bri...

Re: Uprated engine mounts?

They still won't have the performance/NVH suppression range that that the liquid damped OE ones would have. But if you want harder mounts you have little option.

Re: Bleeding Brake Problem

The servo would never have been the issue with a pedal going to the floor unless the linkage was broken tbfh. I would clean all the lines off with solvent, wrap them all with paper towel - especially around the fittings and pump the brakes a few times to see if a weep shows up. Are you certain the n...

Just me going off-topic and reminiscing again...

Re: How does the Honda S2000 compare with the RX-8?

I can't say I've ever heard of many vtec issues. In fact one of Honda's big talking points used to be that they'd never had a failure of the VTEC system on any car back in the K20 days. It's so robust you'd struggle to break it. They're holding their prices even crashed because all the rallying guys...

Re: How does the Honda S2000 compare with the RX-8?

I've driven both, but not for long, maybe 15 mins or so in the Honda at most - just from what I can remember, I'd say the RX8 felt better balanced chassis wise, much more supple and predictable down B-roads - but the S2K felt quicker to react/respond as it feels stiffer sprung. RX-8 is more comforta...
