Back In The Saddle

4 years after retiring my old supercharged Mk1 I've gone full circle to find my self back behind the seat of a trusty miata.

My Old black one - (picture below, #attention) was built up with auto testing in mind, so close gearing, immediate power and agility was the script.

I had a pretty good idea what I wanted from my next MX, Lots of power, not black and ideally something someone else had done most of the hard work on already. Infact I knew the MX5 I wanted, only issue was it wasn't forsale, well 5 months of pestering found me up in Gloucester doing the deal on this:

00011_zpsh3h7l5fj.jpg

Its a UK car on just about 55,000miles. Forged engine, FM2 kit, Hydra Nermisis ECU MK2 head the list goes on. I'm the 7th Owner of the car from new and the 4th that's a Nutz member so its fair to say the car's been a bit of a slut in its time and has had a rather daft amount of money thrown at it.

When I picked it up there were a few running issues, but everything else was bang on the mark, so I did the deal and took the punt on it.

From what I could tell it hadn't been on the dyno since 2012 so I took it upto Scuzzle Motorsport to see what the gig was.

Nick worked his magic and after a few hours on the Dyno and a new set of plugs and leads things were vastly improved! with 230BHP at the wheels!

A2D10926-5587-431B-84FE-341DE988DEBF_zps

That's running around 1.1bar, Nick said the A/F ratio was a little sporadic so didn't want to take it any further and suggest I get the injectors flow tested. So once I've done that I'll get back over there and crank the boost up to 1.5bar to try and get the sunny side of 300bhp.

Since then I've had the front of the car apart to try and clean up the engine bay and get off all the over spray of under seal some buffoon had caked literally everything in. I've stuck a go faster sun strip on too.

Also borrowed some mates Rotas to see what a 7J ET20 looks like in the arches, Present train of thought is to get either some 8" 6UL's in Charcoal, or some RPF01's....

Lots of future plans really, having had 3 totally different cars in the last 3 years I'm hoping to keep hold of this for the for-seable and get some decent track time in the new year!

Stage 1 GV pimp kit arrived the other day!

Also a mate had some yellow film left over so did the TSI's to see what it looks like.... I'm not totally sold...

Also have a new Torsen Diff on its way to me from AK automotive with the Lower 3.6 Final drive fitted, Looking forward to getting that installed as particually 2nd and 3rd gear are too short for my liking at present.

I'm gong to have to up my game to keep up with you at the sprints next year!

Looks cracking. :)

Had the car laser aligned yesterday, which thankfully fixed the lack of stability I was experiencing under braking!

I can now stamp on the brakes and let the abs do the rest. Going to experiment with the fuse out later as i do feel it's more intrusive than it needs to be!

Think I must have a bent lower wishbone as could only get half a degree of camber on this driverside front yet able to get 2 degrees the otherwise!

Presently got -1.5 camber all around (apart from driver side front)
Tiny bit of toe in on the rear
Tiny bit of toe out on the front.

Totally on the fence with regards to wheels on this car. the sensible side of me says some 15x8 6ul's, but the child in me wants some jubiride arches and some compomotive ml's or some other 8/9" lower offset action. Here's what's tempting me...

Wide arches will bump you out of Roadgoing in Sprints as you'll have modified the silhouette. Something to think about, unless you were already planning on going stripped out and modified class.

It's the class you'll run in you need to worry about rather than championship points.

Classes from FDMC Sprint Royale:

Screen%20Shot%202015-10-24%20at%2015.31.

Without arches you'd be in A5 with the Turbo. If you're picked up on the arches you'd be moved into C11. Chances of any silverware in with mad bike powered kit cars the weigh as much as a fart in a paper bag are slim. Also C11 requires a proper MSA cert roll cage to K1 or K2. You can run slicks in that class though. :D

Ah fair enough. I desperately want a wing on mine but not sure I can be bothered with the whole having two boot lids and swapping them about. That top white one you posted looks awesome.

This mated to the 5 speed?

I went full 6 speed and 3.9 TorSen as I wanted shorter gears for more acceleration. It also meant that I could do Solos completely in 2nd gear. On the old 5 speed and 4.3 Viscous I found 1st too short and 2nd too long.
 
#19 ·
6 Speed mate! I've always been under the impression the 5 speeds aren't up to much over 200bhp but seems a lot of people get away with decent power through them nowadays so maybe I'll give one a go in the future, it would make a substantial difference!

Yeah I had the 4.3FD with a 6er before and that was amazing, I did it before I bought the supercharger back in the 120bhp days so it was really beneficial. Once Charged it was still very useful on the autosolo's as I had a 2nd gear that would pull like a trooper from 5mph! On track however I found I was needing to change gear too often.
 
#20 ·
Ah fair enough. I thought about 4.3 but figured that would be a bit mental on track days.

First proper shake down of the car today with our local car club at a Autotest, joined by Ollie on here with his MK1 1.6 Turbo. Great day and out of 46 entries 17 of them were MX5's!

A couple of my videos off the GoPro, first run where I'm trying to impersonate Ken Block and the last run which is a little tider to get the time down!

First video is 10/10 for entertainment. :)

How did you find the turbo compared to the old SC'd car? Also are you running PAS?
 
#23 ·
Yep, couldn't resist. Typically we get 6 runs at our events so I spend the first 3 learning the course and trying to be Ken block, then the second half actually trying to put a decent time in!

The turbo car is certainly not as useable as my charged car was at these events, but the s'charged car was compromised in a lot of ways to be so focused for autotest! That said in quite pleased how I got on today, but tomatoey 1st gear is useless and trying to get the power down in 2nd is a struggle!

Still got power steering, but tempted to loose it to tidy the engine bay up, plus will no doubt feel better at speed! It will compromise the car at these events I'm sure as there is so much lock to lock going on!

Got another day of it tomorrow but round a slightly tighter course so off to bed now!

Congrats on the trophy.

How come you were able to run 595RSRs?
