Tried something a little different today, watch below to  hear a Yorkshire Man rambling about Mr2s!

Took the car to work today, so much better than my executive milk float! 😜

Taking it in again tomorrow, but of a longer run home. Should be enough runs out to recheck all the manifold bolts as they should have heat cycled enough times to work loose if ever they were.

Going to check the front pads this weekend, as they look touch and go as to whether I'll get another full track day out of them, but being tight I might just take a spare set with me and change them at lunch 😂

Pads checked this weekend, got just under half left so that's enough for me!

I'll be taking the spare set anyway at the weekend.

I've also started looking at the big wangs of the carbon variety but still unsure..

Would love to do some back to back testing with one to see what the difference is like.

I believe there was, and hopefully still is, a member on here who is in the brake pad business, maybe he can give some guidance on this. I can't recall who that member was/ is, perhaps someone on here will and post an @brakepadman   post to get his attention.

Gaz2405

Bottled it on the brake pad front and fitted some new blue stuff pads tonight ready for tomorrow. 😂

Think I'll take the hard top off tomorrow for a few laps if the weather is this good.

Great day at Blyton again today, ma aged to get into the high 1.12's and pretty regularly lapping 1.13's consistently.

Car ran like a dream until around midday.

Done pipe was coming loose, nipped it up and again and seemed to do the job.

Then blew through my new steel gasket again whwre the turbo meets the manifold.  Tightened it up again and just loved with the blowing, meant I was only at 10 psi as it struggled to build boost and was running 10.5 AFR's.

Did take my lap top but couldn't be bothered altering the map just for the afternoon, so let it run rich.

It was still within a second of my best times so not the end of the world.

Back home now and manifold off and pit back together with no gasket to see if its any better.

Some of the issues I think comes from running an adaptor from T3 to T25, so I'm just about to press the button on a new churbo, in T3 form which should suit my forged build better in the future. I'm not too bothered about extra spool time at the moment as when you're on track you're constsniin the right rpm range anyway.

OK sooooo started car up this morning... Still blowing from around the turbo.

Turns out the turbo side of the adaptor plate has come loose slightly.

So manifold off again, sandwich plate off to reveal another blown gasket.

So now all back together again with no gaskets, checked all surfaces as best I could with a straight edge and torch and all seemed flat with no warps.

One of the studs around the back of the turbo is an absolute PIA to get to, had to  cut a 12mm spanner down to get in there.

You can actually hear towards the end of the video, the exhaust starting to blow.

Probably doesn't help that I stay out on track for 15 minutes plus at a time 😂

Anyway all back together now, just been out for a test drive now getting my 12.5psi again woo hoo.

With no blows, this is using no gaskets too with only a tiny smear of 1000c exhaust paste.

What power does this run to get 1:12's at Blyton?

Quote from: JB21 on August  3, 2020, 08:21What power does this run to get 1:12's at Blyton?

It was running 233 on a really poor map, and only 10psi.

Now runs 12.5psi, creeping to 14 on track.

So would suspect closer to 280-300ish.

It consistently passes M3's, 135i's etc as well as other track sorted stuff.

Only broke into 12's twice, but 13's was pretty regular.

Struggling for grip now on higher speed corners, looking at aero or slicks next.

You're on slicks aren't you, how do you find them?

Nice figures, thought 1:12's was FAST! I managed a 1:14 in the 2ZZ running NS2R 180 tyres, yellowstuff pads with the ARB's and coilovers set up full soft.

Should be able to get in the 12's maybe 11's myself now with slicks, XP8 pads and stiff set-up with more aggressive geo.

Only managed around 8 laps at Oulton on the slicks but the difference compared to my AR1's was night and day, I'd say at least 2s a lap in it once I've found there limit of grip.

Little comparison video here:

I'm fully braced underneath and run my coilovers more or less fully solid.

How much did you pay for slicks?

R888r's have more or less gone on the rear now 280 miles of track driving. Thinking of trying AR1's next.

R888r's have more or less gone on the rear now 280 miles of track driving. Thinking of trying AR1's next.

Paid £150 for all 4. Fronts are MRF ZTD1 (hard) 190/580/15, rears Hankook Ventus F200 (medium) 200/580/15.

AR1's are very good though and are a step up over R888R's.Lasted ages on mine as well. 6 track days and around 3k road miles, rears are just above the wear indicators, front have around 3mm left on them.

Ebay is your best bet. Just type 15" slicks or whatever size your running.

A little bit of fettling this weekend.

Side light bulb changed out as one had gone, luckily got hands like a child 😂

Also got my scoops fitted, matte black to go with the cage and ducktail.

Need to arrange to get my front spats collected and door bushings.

Next up I'll get my new yaris wishbones fitted.

Looking at a few sets of Team Dynamics Pro 1.2's in 15" to be used as track day wheels, giving me the ability to run slicks if required/wanted.

A few updated pictures below,  car is now running well and I really like the look of the matte black scoops and ducktail.

Order has now been placed for my darton sleeves and machining to match my 82mm pistons. So car will be coming off the road over winter for some fuelling upgrades to support more boost and hopefully be on the way to 400hp.

In other news managed to break a sub 4 seconds 0-60, with a very hard launch on some hot R888rs.

Its only as accurate as the stuff you're timing it on, but feck it. I'm taking it. 😂

So in my quest for more grip and down force I've pressed the button on a generic GT wing, not sure how I'll mount it yet, I'll wait until it gets here.

I've also been playing around at the front with some ducting through the radiator and front bumper which will look like it will require an additional duct/vent to be cut into the bonnet.

In the middle of the car I'm all measured up for a fault under tray, which will start from just behind the front subframe and go back to just past the petrol tank.

At the rear I'm looking to use a lotus elise s2 extended rear diffuser which will go back to another flat piece, and connect to the middle section.

To run this I've ordered a few more bits to jiggle the exhaust around and move it up and remove the cat.

I'm also waiting to collect some front spats which once on I'll make an aluminium front splitter which will connect up with the middle section.

Other than that had an hour or so drive out in the car this afternoon, a little damp to really enjoy it,  but fun never the less and nice to stretchyots legs.

Have found AR1s to be a good tyre, excellent from cold, surprisingly good in the wet, but quite soft so don't last that long.

Where did you find the other 3+ seconds at Blyton over the laps in the video?

Gaz2405

Yeah I've been after a set of AR1's.

Middle of the day track cleared out a bit.

Usually in the 1.14-15's according to GPS.

Go pro wide angle doesn't do it justice how close the cars in front are, need to have a play about with the settings, but it's an old hero 3, so probably out of its depth a bit.

Looking at booking on again soon if you anyone else fancies it.

I have a Hero 3 too so I know what you mean!

Keen for some track action too but want to get my car serviced and tweaked first. Be good to share the track with some more '2s!

Gary, have a look at this before you cut more bonnet holes - it's quite a good vid

Great watch, will hang fire on an extra vent and the diffuser for the time being.
