Honda S2000 engine and box

Hey Dave

Glad to see you're still going forwards. I lost some inertia over the spring (note the use of seasons now rather than months) but am now back at it.

Your pedal set up prompted me to upload my unusual solution on my blog - being taller Ive been wrestling with legroom and happened to come across a pedal box with vertical masters to create a little more space. As you, I didn't want to have the masters close to the wheel so they are inboard.

I love the way we come up with solutions and it is great to share ideas.

Keep up the good work
Gavin

Hi John
using 205/60/13 on 6 1/2 inch magnesium minilites.

Here is the gear calculation based on the 3.62 diff and Honda 6 speed box with max revs of 8900.

Cheers
Dave

Hi Sandy
I made a template from flat glass sheet then folded a sheet of stainless to use as a mould for the pedal box mounts which I then bonded in place.

Hi Dave,
Well at 170.6 mph, it should be fast enough! My issue with the Honda box is that 6th gear is too low. I occasionally contemplate using a T5 box with the S2000 mill. First four gears are similar to an Elan with a .63 over drive fifth. Talk about having one's cake and eating it too.

I noticed that you went to a Sierra final drive. Do you think that the Elan rear end cannot be made strong enough to cope with 240 Japanese ponies? My issue is that the cost of getting a Sierra diff and shipping it over to the Great White North would make even Tony Thompson's parts look cheap.

your work looks nice and tidy dave and continue as you need to: you should see what a brilliant british fabricator is capable of doing - those are the REAL magicians: templates made of cardboard AND 30min later you have your chromemoly bracket for lets say a side pod! sandy i luv those guys!!

Hi Jonny
I'm sure with the correct bits the diff could take 240 BHP as the race Elans regularly run around 180 and they are doing starts where they drop the clutch at 6500rpm with sticky tyres.

I went for the Sierra diff to allow for the fitting of throttle bodies later which will up power to around 290bhp and maybe even adding a supercharger!!!

I have a T5 with the ratios you mention with an alloy belhousing to mate to a Turbo twincam. The big step from 4th to 5th would drop the Honda motor revs off cam and could cause other problems.


If you ran a 3.54 diff or even a 3.77 that would be ok with the Honda box and that keeps things simple at that end.

Cheers
Dave
