- Best lap so far at Big Willow in 190WHP NC Miata . Some fun chase with Nissan and Porsche . MX5 was definitely low on power as always but managed to close up to both cars in corners . Ended up being quicker on RT660 tires than R7 Hoosiers since I never managed to bring those up to operating temperature of 180-200F(82-93C) very low grip on second run with tires being at 140F(60C) .

Thanks
that song was a banger lol. nice driving!

Horse was dead , lol
Got new engine now .
Nice driving, the car looks in pretty good balance. Did you run the car with the OE differential or aftermarket diff?
Thanks ,
First two years it had ebay used stock LSD but in last two years it has
OS Giken like in this video .
Hey man, just picked up a nc for track car duty, was wondering how many miles/track days you have put on your 2.5 and how it is holding up? thanks!
It depends on how hard you will use it (mostly rev limiter ) in my case 7,000-7,400 on 2.5 engine that is not made for high revs it comes to about 40 track days . If you keep it to 6,500 it should last much longer .
I'm italian,I have same car, same engine, 5 gears it's a very nice car but street configuration with less aero things and without rollbar.
What tires and pressure would you advise me for occasionaly track day?
Ps. Your videos is awesome❤❤
Thanks , forza Vale 😀
I am using RT660 , AO52 and sometimes Hoosier A7 . Sizes 225/45/17 if your wheels are 9J or 245, 255 /40/17 if you have 10J wheels . My tire pressures are usually very low like 29psi(1.99bar) front 28psi(1.93bar)rear hot . I get most grip like that but car can feel little bit less responsive and side walls could get some damage depending on the track . If you are not chasing last hundreds of the second go with 31/30psi. (2.1/2.0bar) that will be safe and good enough .
Very nice driving. I've just started racing my '07 in time attacks and similar events under #46 too!
What cooling mods do you have?
That's cool ,46 number is so legendary . I have Koyorad radiator , oil cooler and no thermostat since in CA is pretty warm all the time .
@@driver46 thanks for replying. I'm still stock but plan on adding the oil cooler at least. Have you just piggy-backed off the stock filter attachment point? Because I've read that the added stress of sandwich plates, hoses, gauges etc hanging off that cantilevered housing can cause it to fail on track.
Also, have you upgraded brakes? I didn't see any cooling ducts. Or do the fender vents aid brake cooling? I'm finding my stock brakes are performing very well with upgraded pads, hoses and fluid. Don't know how much harder I'll be able to push before I reach their limit. I'm just a beginner..
I'm in a similar climate to you in Australia and didn't actually consider removing the thermostat. It does get down to ~5°C on occasion. I find the car warms up very quickly.. perhaps I should consider it. I still 'semi-daily' the car and can't go full racecar without removing the PRHT
@@dielaughing73 if you daily it leave thermostat in , worst case you can buy one that opens early . While being stock I had 0 issues with cooling on stock system . During 2.5 swap I did radiator and oil cooler . I use sandwich plate and so far housing never failed on track , I did break one by over tightening it but that was on me . Stock brakes are good enough for very hard use and only difference with upgrading front calipers will be in better feeling since they will flex less . I did upgrade after few years of tracking to Racingbrake.com since they sponsor me and those rotors will last forever on this car . I added cooling ducts instead of fog lights but I mostly keep those closed , only ove 100f (35c) I l open those.
Also I use 5w-40 oil
@@driver46 good to hear it manages heat well with stock power. I have been wondering because I don't have a gauge for oil temp or pressure yet. Water temp via OBD has been fine on track, though I've only tested it in winter so far.
I run 10W40 race oil and want to get those fog-light brake ducts, lots of other things to buy first though. How often do you change your oil? I last did it after a few track events (but less than 1000km) and it was already a bit thin and dark in colour
@@dielaughing73 good choice of oil , I change it after 2 to 3 track events depending how many sessions I did during the weekend . If you want to aim at km covered multiple all track km by 20 and that will be your wear and tear in normal driving conditions . Also you should have oil pressure on your stock dash ( not very precise) but should give you idea if everything is alright.
Nice! You mentioned you swapped to a 2.5l, are you using an 06-08 trans?
Yes
Your 2.5L swap went from 160 whp to 190 whp because of Stage 2 cams? Any other mods?
If I remember correctly it had 169whp with stock cams, with stage 2 cams I added 550cc injectors and racing headers . That is all I did for power .
Is the 944 an S2?
I am not sure
