You should be quite proud of what you've built there with the Mongrel. It's certainly the model of what you can do if you persevere in the face of insurmountable troubles.
No matter what, that car is so cool. So happy it's trouble free. That car that left you in the straight away must have been extremely surprised when you came up behind him in the chicane area. He may have affected your track time a second or so as well. Thanks again Matt, for bringing us along.
Nice exposition on the difference good tyres make! I remember in my 'yoof' in the '90's being stopped by a copper while I had some, erm, 'marginal' tyres on my car, he gave me an excellent piece of advice I've never forgotten - he told me: "All your brakes do is stop the wheels; it's the tyres that stop the car". And he never even fined me or gave me points either! It worked - I've always had good tyres ever since and I wish all coppers were like that guy!
I was watching the video thinking i wouldnt be able to push a car of that era so hard without a full on roll cage.... Then i noticed it has a proper cage. Thats an amazing install you can barely tell its even there. Some great fabrication and thought have gone into that. Catching that civic with ease in the corners
That's a good improvement Matt, out of experience of owning a Mk2.5 Mx-5 I always felt the 6th gear a bit 'lacking' and grippier tyres would have a greater rolling resistance ?....Just keep it nailed in 5th!....lol.... Fair play for wanting to keep it N/A too, one thing that did show was with the Mx-5 underpinnings you made up time in the corners!
With a consistent car you can hone your skills to suit the machine, and a reliable car makes you a more pleasant person to the rest of the world. You can do this for yourself or the cheerleaders, best of luck Matt.
I wish someone was with me when I watched this, I said 3 seconds when the guy gave the go ahead onto the track. Very satisfying to see her run, I still can't get over how sweet she sounds, there is a clip with a newer car in front, kind of a high pitch whine, then the Mongrel a nice deep throaty hum and another car behind again a high pitch sewing machine for me it is a night / day difference in which sound I prefer. I cast my vote to keep it Natural. Well Done and Thank You for sharing with us.
Keeping the Mongrel N/A warms my heart. Now you just need to tune it to the max. Making power N/A is an art form, a learning journey that I fully recommend on taking. There is still a lot of power to be freed from that engine, although the 4.3 final drive ratio also helps.. If there is enough power band on the top end to actually push the car further than the current top speed.
Definitely something to be said about having a vehicle that you can just track all day long. The different diff ratio might make you faster, but the downside is more gear changes. Same happens on the little bikes I've been playing with, change to 1 tooth smaller in the front and pick up some acceleration to pull out of the corners better. Never hit rev limit in top gear on the little tracks I've been on, so not an issue.
3.5 seconds a lap quicker! That's a fantastic improvement, and just from the tyres. I'm sure you can find a way of tweaking a bit more out of the engine too. 😊👍
Well done Matt. The tires def a step in the right direction. A turbo or charger is too much heat plus there's a lot of pride, my opinion, of having it all engine. So yeah, 5 speed it is. Love the car, love the channel.
Matt you’ve nailed it I love this little car reliable fun and your channel always brings a smile every episode ,if it’s fabs or car builds it’s great good luck at Cadwell watch the leap very light at the top but great fun been round in 3.5 works rep Rover long time ago interesting 👍👨🏻🏭
It’s great to follow your channel, but looks like at high speed at the start of mid corner you could go a couple of clicks stiff on rear suspension, or more negative camber on the rear which will stabilise at higher speed on turn in to your apex. Good luck fella cheers.👍
Premium noise indeed. Please help me out. Did Matt build the Mongrel on a 1.6 Miata or a 1.8 one? I own both a 85kW Miata and a 96kW and I'd love to help out. On the Diff matter. Yes, the six Speed is useless compared to the five speed though it can manage a bit more power. If the mogrel is a 1.8 car, there is no 4.3 Differential. That's because the 4.3 was for the 85kW 1.6 Generation NA with a 6" ring gear even as VLSD those are avoided as those units are already struggling with handling the power. When the NA generation of Miata got its facelift and the 1.8L became available, Mazda switched to the 7" 4.1 Diff (and even a 3.6 one). Shorter ratios are possible though with Kia parts swapping out ring and pinion of a 7" differential achieving a 4.6 ratio. There are guides out there, way better than my comment. I am very happy with my 96kW Miata with a 5 speed and the 4.1 Differential.
Thanks for the confirmation. Why did Matt state that the Mongrel only has around 125 horses though it should have around 140 from the start, the Mongrel Frame being a six speed 1.8L NB?
@@Urchfab Thank you Matt for supporting my lazyness of not getting the data out of old build videos 😅 Okay. 122 at the wheels. Did the Dyno measure drivetrain losses for calculating power at the crank?
You are spot on Matt. The Mongrel will make you a better driver forcing you to find every ideal line and nail braking points. If you do add power later you will know the car like the back of your hand. Enjoy the reliability 😁
Magic job Matt been following the whole build on this, love what you have achieved mate, pretty cool if you ask me, and yes it looks like a mongrel meaning tuff, looking forward to seeing more cheers KC Tasmania Australia 🇦🇺🇦🇺🤝🇬🇧🇬🇧😎🙂👍
Three seconds and more confidence in the feel,good result. As said now approaching the cost too improvement juggling as if the car can now use the power it has then getting more gets expensive and then the car may need further mods to handle the increase.
You took the words out of my mouth. A 5 speed box, to me, sounds like the way to go. Should be light, too. I noticed that when you came out of a certain r/hander, you had more grip and it wasn't drifting off, so you don't lose time over correcting the drift.
Yeah, tinker with ratios first and then do mods to the cyl head as needed . Raising the compression 1 point and some porting with bigger inlet valves will be interesting
Great car and always great vids. A bit wollowy through church and with a bit of chassis tinkering you might have another second or two. Try it a bit stiffer in the back and play with disconnecting the front roll bar.👍
I used to rave about Toyo tyres, always used to be vert predictable. Fitted T1-R to my st150 and swapped them out half way through there life, I’d almost go as far as saying there no better than cheap ditch finders.
I really like the R888r. I didn't notice any difference between the R888r and Nankang AR1 even though the AR ate about 4kg heavier. AR1 are about 10mm wider so that may help. AR1 are also nearly half the price.
One thing I noticed from the in car camera was that you weren't having to correct the car except for one time!!! PS ,lm with everyone else, love that car,and enjoyed the build. How 'tired ' is the motor, seeing as it was second hand???
Is it possible to replace 6th with a shorter gear? Perhaps 5th as well? Keep you a lil more in the powerband in the high end? I've heard the 6 speed is a much stronger box than the 5 if that's true you may want to try and keep it. Also, couldn't you go aftermarket for the ring and pinion?
To be fair they're already incredibly short gear ratio gearboxes. The 6th on a 6 speed mx5 box is the same final drive as the 5th on a 5 speed, and the top speed will be barely 200kph
RX-7 gearboxes and diffs have some interchangeability with MX-5's. I don't know the exact particulars, just that, that's where I'd be looking for parts. Maybe not diff gears but the whole diff. Rx-7 diffs are stronger. If he makes a lot more power the gears can be longer and it will matter less :-)
Nobody ever expected a 100e to get down the tarmac in that fashion mate. Those three seconds looked fast as F*** on camera bro! And if you were following your previous self it looks like you would be quite late to the finish line on the previous tyres?LOL. The one thing I was inspired to mention; is that rollcage up to spec for those speeds? Ha ha ha. (May you never find out either way by testing it! ) That's it, Cheers.
Car looks great 👍I don't know if you guys had the fe 2l engines or if they were common enough, it's a great engine for this. Maybe a bit heavier. Still able to use the same gearbox etc.
Those Honda Type R's aren't exactly slow in the corners but you were raking him in. Nice driving!! When you're board of the 1.8 how about the Jag v6 conversion. Should increase the power to 250bhp on bodies. It'd make more content and would be a great upgrade with a screaming V6!!!

I'm pretty sure all gearboxes are 1:1 in top no matter how many gears they have so changing to a five speed won't fix the final drive ratio and will make it harder to keep the engine in the power band because you won't have such a close ratio between each gear.

Front wheel drive gearboxes have the diff as an integral part of the gearbox so usually they only quote the over all drive ratio.
Thruxton and combe are flat out fast circuits, cadwell will produce some giant killing chances 🤣 i have a turbo and naturally aspirated pair of track cars too and the N/A has finished every track day for the last 15 years, the turbo hasn’t finished one of the three it started. Turbo one is saab powered btw 🙄
Brakes : A bit further exploring required. Best bang for buck. ...and for the love of Zeus, get your rev matching sorted on your downshifts, please ✌️😁
i was thinking the same thing. doesn't change the exhaust note, does not rob power like a supercharger when you are putting around town. small shot of nitrous just when it really needs it at the top end.
What about a 4.44 LSD from an rx8 ? Should be plenty available from all the rotters and Cars with shagged wankels. Would take a little bit of fab work to mount it in the subframe but driveshaft and axles appear to bolt up. Shouldn't be an issue for a man of your calibre.
Gears higher than the 4.3:1 the Miata has will improve his accel from start and in the middle but will cost from max speed- he has almost enough speed to hand on the flats- and not too shabby handling- he needs more power at the top end to improve his "hold" on his exit speed, so he doesn't slow down. He has the rpm/rear axle ratio- he lacks the power under the uphill load to keep the accel he has. FR
Toyo have given you tyres but they've also screwed up the equation. Too tall.Go back to a smaller size and get the most out of the gearbox.You'll have faster down the line speed and that's where the lap time improvements come from. But I get it, you want to have fun. The car is overshod. A narrower tyre will give you heaps of fun and much more warning.
You should be quite proud of what you've built there with the Mongrel. It's certainly the model of what you can do if you persevere in the face of insurmountable troubles.
Thanks Brian, I am. Cheers

Never heard that phrese, before, "she looks the tits". Love it!
That's a big step forward in lap time.
Have you tried your different length inlet runners yet?
Not yet.
I'm pretty sure all gearboxes are 1:1 in top no matter how many gears they have so changing to a five speed won't fix the final drive ratio and will make it harder to keep the engine in the power band because you won't have such a close ratio between each gear.
Most modern gear boxes have an over driven high gear.
In the case of my Mercedes 6 speed both 5th and 6th are overdriven with no 1:1 ratio.
my Skoda ( so i assume most VAG group cars ) 4th is 1-1 , 5th is .85 & 6th is .70 ( ish )
@@888johnmac 1:1 refers to the gearbox input/output shaft ratio before it goes via the prop shaft through the rear diff ratio (normally 3.something:1) to the wheels, which is the over all drive ratio. Front wheel drive gearboxes have the diff as an integral part of the gearbox so usually they only quote the over all drive ratio.
6th gear is an overdrive, 0.8 to 1. The final drive ratio is something else again. Overall ratio is the two together.
you probably mean that just about no car with more than 4 gears has a 1:1 top gear. this has been the case since the 80s. Overdrive to save fuel.

Sounds a gearing related issue more so than power. Keep it NA!
Gears higher than the 4.3:1 the Miata has will improve his accel from start and in the middle but will cost from max speed- he has almost enough speed to hand on the flats- and not too shabby handling- he needs more power at the top end to improve his "hold" on his exit speed, so he doesn't slow down. He has the rpm/rear axle ratio- he lacks the power under the uphill load to keep the accel he has. FR
get a exhaust whistle must be 500hp in those alone lol
K24 swap? So many US Miata guys are doing it lately.
Where is me rev counter you promised?...... 😢 LAG
Its here!
Yay!!!!...... LAG
Mmmmmm mushy peas!
Turbo should solve it too
Toyo have given you tyres but they've also screwed up the equation. Too tall.Go back to a smaller size and get the most out of the gearbox.You'll have faster down the line speed and that's where the lap time improvements come from. But I get it, you want to have fun. The car is overshod. A narrower tyre will give you heaps of fun and much more warning.
NA with a big ol tank of laughing gas is still NA right? Do ittttt
A turbo would cure your lack of power.
So mongrel. Yet so purebred.
