george_seamons Posted March 30, 2015 Report Share Posted March 30, 2015 Its a (hollow) threaded shaft with a hexagonal head. A bolt by all accounts...just a hollow one! Quote Link to comment Share on other sites More sharing options...

SamKidney Posted March 30, 2015 Report Share Posted March 30, 2015 Jardo, look into a master cylinder brake stopper if they're available for your car. Bolts to the strut tower/something solid and sits against the back of your master cylinder and prevents it being flexed forwards into the belt when you brake. Improves pedal feel further too!

Improves pedal feel further too! 99% of the ones ive seen mount right at the end of the master cyclinder, so it's be no use in his case. guess you'd mean more this design?

MartMini Posted March 30, 2015 Report Share Posted March 30, 2015 depends alot on the car and how strong the bulkhead is. Get someone to sit in the drivers seat and stamp on the pedal, you'll soon see how much the master cyclinder moves! 1 Quote Link to comment Share on other sites More sharing options...

Greetings Posted March 30, 2015 Report Share Posted March 30, 2015 Highlights vid from this weekend... That was a thrilling watch Adam, especially 2:48 and onwards. Well held, nicely avoided and well held on the grass too Looks like such an enjoyable and skillful racing series. What tyres do you run in the wet, NS2's? Do you have ABS? Also intriguing lines in some places but they seem to work better than your competition. I'd love to see a g-meter in your vids one day. What kind of G's do you think you're hitting and what's that box in the middle of your dash? Quote Link to comment Share on other sites More sharing options...
Duncy H Posted March 31, 2015 Report Share Posted March 31, 2015 Mx5 people (Tarty Adam) I need your help. On the way to work this morning my mk1 eunos ran a bit rough at idle at times and twice I felt a bit of hesitance when accelerating away. Any pointers? I've not had chance to have a look at anything yet. It's been hammering it down if that could cause issue. Quote Link to comment Share on other sites More sharing options...
MadManMike Posted March 31, 2015 Author Report Share Posted March 31, 2015 Does your idle go up and down when it's cold? Try a diagnostics tool on it, but if it's anything like mine it's just the idle control valve either needing cleaning or replacing. There's a few things it could be though, so get it on the diagnostics and see what code you get. Quote Link to comment Share on other sites More sharing options...

What kind of G's do you think you're hitting and what's that box in the middle of your dash? Cheers dude, same for your vids! Haha, yeah there were a few hairy moments, keeps you on your toes though The level of driving does seem good yeah - for example a guy who won Formula BMW in his first season, got onto the Red Bull academy, won 14 out of 16 races in another series in 2012 (his first season racing that car) and nearly won the MX-5 Mk3 championship last year qualified 16th, DNFd the first race (span into the gravel) and was 25th in Race 2. The control tyre this year is the Nankang NS-20, it's a budget Chinese road tyre, about £35 each over here. If ABS was fitted to the cars as standard (rare), it must be removed to comply with the regs. Yeah, I tend to spend quite a lot of time playing about in the wet to try and find where the grip is, the regular lines get so polished up they are like ice, so by taking outside lines and braking about a car's width inside where you normally would you can often find more grip. You travel a bit further but the key with such little power is keeping the car rolling... The box is my datalogger - I'm pulling about max 1.3g lateral / 1.0g braking in the dry and max 0.95g lat / 0.75g braking in the wet. The fact I barely ever seem to lock the brakes means I'm not trying hard enough though Quote Link to comment Share on other sites More sharing options...
Duncy H Posted March 31, 2015 Report Share Posted March 31, 2015 Cheers for the help folks, I'll try an Italian tune up on my way home and then lift the bonnet see what I can find. It did it when car was warned up. I have a theory it could be that I had heaters on full in idling traffic so battery may have discharged slightly.

AdamR28 Posted March 31, 2015 Report Share Posted March 31, 2015 Hmm. Could be you know! The alternator should kick out enough juice, but being old it may be a bit less efficient then previously. Guess a multimeter will confirm Should be over 14v while the car is running. Quote Link to comment Share on other sites More sharing options...
craigjames Posted March 31, 2015 Report Share Posted March 31, 2015 Do those sorts of things really make a difference? Looks like a quick little project that'll cost naff all if so Makes a massive difference in my old mans hill climb car. It's fitted with a Cusco master cylinder brace that fits under the front strut brace on the drivers strut tower. Without it you can watch the BH flex 5-10mm, with it its rock solid.

The fact I barely ever seem to lock the brakes means I'm not trying hard enough though Wow, that's a lot, I was convinced it'd be in the region of 0.95 in the dry. Amazing performance from those tyres then. I've pulled a maximum of 1.25g lateral on WTCC slicks, probably because of the weight. How much does the MX5 weigh? What you say about the difficulty seems to be common - amateur events appear to often have better drivers than the semi-pro stuff like GT3. At the end of the day, the difference between pro and amateur is mostly the budget you have at your disposal. 1 Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted March 31, 2015 Report Share Posted March 31, 2015 It's more the chassis I think. The camber correction of the wishbones is amazing. Soft suspension works well in some cases The MX5 is 960kg with driver, and we're on 195 section tyres. Makes sense and I would agree. Prime example right here at the front of our grid. Check out how the red and white car gets a crap start then somehow is in front into turn 1! That's just a plain power difference... Quote Link to comment Share on other sites More sharing options...

After a quick google is it basically driving your car on the rev limiter for x amount of miles? Quote Link to comment Share on other sites More sharing options...

Yup, works absolute wonders for diesels too as when the cylinders get hot enough it burns all the crap off the injector heads that's built up over time from driving like a vagina. 2 Quote Link to comment Share on other sites More sharing options...

MadManMike Posted March 31, 2015 Author Report Share Posted March 31, 2015 I wouldn't say rev limiter for a few miles is a good idea, but certainly try a gear lower than you would for longer than you would. Stick some Redex type stuff in your fuel when you do it, helps to burn shit off! Quote Link to comment Share on other sites More sharing options...
Azarathal Posted March 31, 2015 Report Share Posted March 31, 2015 I normally shift just before red line in 1st+2nd and then use 3rd to engine brake and then repeat. I grannied the mr2 around for a few weeks and when I did that you could actually see black shit flying out the back Quote Link to comment Share on other sites More sharing options...
MadManMike Posted March 31, 2015 Author Report Share Posted March 31, 2015 The Eunos is most responsive after 4k, so naturally I try and leave it around there most of the time 1 Quote Link to comment Share on other sites More sharing options...
