My daily and the weekend toy - warning, get coffee. And food

[Juno8]

Son of a [Swear Expunged] I have haha, an S2000 engine...thats a Honda VTEC system man oh man those are reliable engines 15 million sold...NOT ONE has ever broken down add on a supercharger...you have got a real torque and power monster there

[PhillipM]

~350bhp initially is the aim, there's enough flow capacity in the filter/cooler and charger to go past 500bhp if required, but I think the transaxle would be in pieces by then.

[Juno8]

have you had the supercharger up and running yet?

[PhillipM]

Nope, it's not running yet, still waiting on bits for the plumbing and I need to finish the wiring off.

[Juno8]

thats annoying, bet its gonna be at least twice as fast or faster still than what you have it originally lol

[PhillipM]

Originally it had a ~90hp VW aircooled engine in, suspension that was about half as good and shite tyres, so it'll be rather more!

[Juno8]

with a supercharged Honda VTEC engine in it I guess about 140mph+ depends on weight and stuff

[PhillipM]

It's geared to top out at ~130mph. If I fit the shorter ratios, about 115.

[Juno8]

not bad for a rough guess I have to say but I guess you want all that juicy suckling torque to be available on Rally spec gear ratios if that world rally spec exists haha

[PhillipM]

Well, the aim is to have a choice of two gears which the car will pull well in for any given corner - as the conditions change so much from one run to the next you might find a corner you were changing down to 2nd for is suddenly better in 3rd because it's so slippery you can't put the power down anyway, or one you were taking in 3rd has been dug out in the middle and the car sinks into the earth (it takes SERIOUS power to shift a car even when it's only sunk a couple of inches into some mud) and 2nd would be better.

In either case a gearchange in the middle of the corner may be the worst thing as you will loose momentum for half a second, so having ratios and a spread of torque wide enough that it can manage in either gear, whilst it may cost you a tiny bit of outright pace on the smooth stuff, can easy gain seconds per corner when the going gets tricky.

[Juno8]

I dont know if this exists or not...would a dual gearbox system work?

[PhillipM]

No.

A nice sequential 6 speed gearbox would, but the price is about the same as it cost for the entire car

[Juno8]

did a bit of research into what I said and that gearbox I said doesnt exist but yeah a 6 speed sequential would be pretty awesome but the cost would make you think again about it...

[PhillipM]

£12,000 for one for this, or £8000 for a 5 speed that's not as strong....plus £1000 for the LSD, and another few hundred for the gearlinkages.......

[Juno8]

£21,000....
