JohnTurbo's B18C EK4 Race Car


I stuck a 1:1 in and won my class which was nice! Its a bit long but it saves the engine on tracks with long straights.

Im assuming so Stephen - 2 failing rules out chance.
 
Good to hear, hopefully you have more luck with the latest 5th gear and keep enjoying the racing :)

Anglesey Circuit - Tintops '14. Class win, 1:22.8 best lap.
 
Well done, great car and always looks great on the track!!
 
Great photo & result :nice: Any in car footage? How are you finding the racing in Tin Tops? Hope to be back there next year in the DC2 along with Bigskank in his 9 :D
 
Its great! I tend to get bullied a lot, especially at the start.

Be good to see you in it - assuming I can afford to keep doing it!

Forgot the camera at Angelsey :(
 
I love the starts, 30 cars into the first corner, getting boxed in & carved up, looking for a gap! Its expensive but worth every penny. Missed the first & last race videos last year due to technical issues, its annoying :angry:

Matt...I will let you know :D
 
Excellent work from Stephen and yourself, I'm looking forward to more updates from the tin top series.

I'd like to try it next year if I have the funds.
 
Well...

I got a tiny mention in Autosport for my "straightforward class win" at Anglesey.

Car was left on the trailer needing no work for Donington Park!

In qualifying however my rotor arm disintegrated and took out the dizzy cap too.

Meaning ANOTHER one of these shots:-

I borrowed a rotor arm and got it running. I managed 35 mins of the final though from the beginning it wasn't running great...then it started dropping out of Vtec...
Then the engine semi-let go, and a loud banging. Managed to get her to the pits this time, but game over.

Having completed most of the race I was 'classified' as last.

Then I got hauled infront of the Clerk of the Course and my honesty about an overtake under yellows netted m 4 points and exclusion.
That means they struck my result "last" from the race results!

All in all a bad day.

Anyway, no to be put off I'm working towards Oulton on 20th of September. (Come along anyone?)

I was lucky enough to get a 16B bottom end from Nicole. [Knowledgable girl!]

So car is in the garage, jacked up waiting to pull the lump for the 4th time!

I admire your persistence, you have no luck with engines or boxes! We mustn't be driving ours hard enough
 
New engine fitted and running. here was a bit of a leak issue with oil and water(!) but now resolved and timed up etc.

Took a bit of building from a bare bottom end, you don't reallise how much stuff is bolted on!

So I provisionally wired up my oil temp/pressure gauges this evening. They're wired to the 5th switch as they're bright....but i wanted gauges with a warning light for low/high conditions as i won't be watching the mid race!

Then I started on the stripdown of the old lump to see what happened.

Lots of metal in the sump and pickup:-

General stripdown carnage..

The offending area...piston 2 big end.

Crank:-

Block is totally fine.

But what remains of the bearing shell isn't very substantial!!

Wow, nice 1 just in time for Saturday. Pick my engine up bits for machine shop this week , time to put it together . Then go testing
 
Where did all the metal come from then? Looks to be to much to of all come from one bearing?

Sump baffles are a bit odd to not seen them quite like that before
 
Maybe a silly question but are you changing engine oil before each race?

Also what grade of oil are you using?



Could simply be the case of a tired oil pump failing but if looked after they are usually good even at high mileages
 
The oil was right at the bottom of the dipstick when I came in. It looks like a lot escaped at the head gasket, front timing side during the race.
Even with the baffled sump I suspect it got surge and span the bearing. Its a shame, the bottom end looked in gread fettle otherwise. It's probably done less than 20k miles as its always been a race car engine.

The other bearing shell was totally absent from that big-end. That explains all the metal - also that one in the photo is wafer thin!

I'm going to take the advice of a DC2 racer and overfill by 2mm on the dipstick
 
I would always overfill my cars by a few mm on the track to compensate for the oil moving to one side during hard cornering and the fact that most Hondas burn a bit of oil, I also check after every session

I'm currently using Millars 10w50 motorsport oil in the DC2 and it has been great with very little oil buring off on the track and oil temps staying at a steady 110 degrees with a Mocal oil cooler. The car is rev'd to nearly 9000 in every gear dropping to no less than 7000 between gears with the gearset

I always looked at Honda engines as bullet proof and "touch wood" I have never had an engine or gearbox failure in the past 9 years of track driving with various different Hondas


Hopefully this is the end of your bad luck
 
Both engines went after hard braking followed by a fast but sharp 90degree turn when getting back on the throttle.

Recently Im using 0w30 full synthetic - but the oil is not the issue here for sure. Laterly I just lost too much oil in the 40min stint to cope with the oil moving. Im pretty confident thats the cause. It was on the full mark at the start.

I should have stopped when I noticed vtec engagement being a bit funny on that corner...but Im a bit singleminded in a race.
 
Its hard to think that fast when it happens though

Im no expert but I would be using at least a 5W40 oil on a Honda track car, 0w30 will be very thin at those sorts of oil temps (without an oil cooler at least 125 degrees) and will not give great oil pressure. It will also get past the rings easier and burn off during the race

With a 10w50 again you should have better oil pressure at those higher track temperatures which should help keep the crank away from the bearings. Any race guys that I speak to running all sorts of engines from, zetec, millington, Honda, vauxhall all swear by the Millars 10w50 for a good race oil
