Fast can mean many things to many people, it’s all subjective, but, there’s some things that everyone must agree with. When we’re talking cars, I think it’s a pretty unanimous decision that an Aerial Atom, or a Bugatti Veyron is fast, so, when we’re talking about a car here that eclipses their power to weight figures – 498bhp/ton for the Atom, and 521bhp/ton for the Veyron, compared to a whopping 541bhp/ton from this little Honda – we’re talking about something pretty special…
To put a little background to it, this car’s been in Marc’s possession for quite some time, having been through various N/A builds, and spending countless hours ripping up the tracks. However, when a turn of bad luck lead to a poorly engine on a trackday, he decided enough was enough, and it was time to go to the next level. Being friends with Rick from Race-Tech (http://race-tech.net/) meant that this build was going to go one way, and that way includes strapping a go-faster snail to the engine.
Having developed the car over a number of years, Marc had already satisfied himself with rather extensive chassis tuning, in it’s current spec, the car’s running Mugen 5 way adjustable suspension, Buddy Club roll centre adjusters, Omni-power front control arms, SPC front camber arms, a Whiteline front ARB, which opposes an ITR ARB at the rear. The rear’s also running Function7 control arms and Buddy Club camber adjusters. The overall alignment is something that’s been developed over the years, with a little tweaking here and there to get the setup feeling just right.
Stopping power is provided by EP3 CTR brakes up front (running Accord Type R 300mm discs), with EK9 260mm brakes at the rear. A 5 stud conversion allows a set of Advan RG wheels in 16x8F, and 16×7.5R, running Maxsport RB5 tyres all round. As i’m sure you will have noticed, the exterior’s certainly not for the faint-hearted, painted to replicate the BP Trampio JGTC cars of old.
On the inside, are a pair of Mamba carbon bucket seats, with a pair of 4 point harnesses, and not a great deal else, after all, if it doesn’t make the car go, stop, or turn, what’s the point of it being there…?
Now, onto the piece de resistance, the engine, I left this ‘till last in a hope it’ll mean it doesn’t overshadow the rest of the feature too much. The basis for this engine is a B18C4 block, as found in the ‘Aerodeck’ estate versions, or the MB6 5 door Civics, however, it’s what’s inside that matters, a B18CR crank, pushes Crower I beam rods, which are mated to ACL bearings, and 81mm NPR Turbo pistons up and down, the head is a P72 head, fitted with Skunk2 valves, springs and titanium retainers. Air is first sucked in via the huge Precision PTE5857 billet turbo mounted in the front bumper, and using a V-Band setup, where it flows, with next to no piping, through the custom Race-Tech intercooler and piping, into the Race-Tech inlet manifold, and through the engine.
Once the air’s done it’s part and created the power, it obviously needs a nice, simple exit route, and the exit doesn’t get much quicker than out through the – rather beautiful – forward facing Race-Tech manifold and straight out through the exhaust that exit’s through the side of the front bumper. Twin Tial 38mm wastegates control the pressure, and an Apexi AVCR and Hondata S300 ECU, mapped by Race-Tech ensure everything’s running fine and dandy.
The power’s put down through a stock S9B gearbox and LSD, with stock shafts, and an LSD motorsports clutch cover, with a generic organic disc. And power is indeed put down, surprisingly well, provided you don’t simply use the throttle as an on-off switch, feed it in nicely, and the delivery would have you wonder whether it was actually a bloody big turbo up there or not. Until the power kicks in, that is. And boy does it kick in…
Now, for the figures, these are what most of you will, i’m sure, be able to relate to most. In it’s old form, running a smaller turbo, and less boost, the car ran the 1/4 mile in 12.0s @ 120.5mph… On road tyres. Having had it on a weighbridge, the car weighs in at a mere 840kg, and recently made a whopping 455bhp @ 1.4bar, pulling 335ft/lb in the process, now, can you see where those amazing power-to-weight comparisons come from…? Oh, and just so you, know, Marc’s planning on running more boost in the future. Scary thoughts? Yes.
If you ever see this car come up behind you, don’t worry about moving out the way, i’m fairly sure it will have very little in the way of issues when trying to pass…
