    If I were starting again I'd look seriously at a hydramat. The way I see it now, I can probably do the relocation for next to nothing.

    Ah, well as long as the pump from the fuel cell to the surge tank is always primed it won't matter that the surge tank is higher.

    And finished the bonnet latching. The front 2 brackets were a little more tricky due to guard/bonnet curvature and concourse/symmetrical panel gaps...

    Under manufacturer recommendation I've used a traditional pin for the middle front, made up a little spacer so it's wedged in tight. This took a bit of adjustment to get just right because of the original dzus bracket height and it's proximity to the bottom of the bonnet.

    I had to remove the rear bonnet posts (pictured) as they were making it very hard to remove the bonnet. Every time you gave the bonnet a slight lift to release the latches the opposite side latches would click back in. By removing the posts you can lift and slide from the front of the bonnet a lot easier.

    But removing these posts means there's little to no support at the back of the bonnet. So I made up some brackets out of aluminium angle so the bonnet doesn't sag in the rear corners.The rear corners may well vibrate a little, so may put another couple of quick latches there, but will try it first as, really, the car is hardly the last bastion of NVH quality.

    Over all I'm very happy with how it's turned out, the bonnet is far easier to remove and put on and is rock solid once down in a way that it never was with the dzus clips. Win!

    Reorganising the garage today and giving it a good clean out. Have to admit, cracked a bit of a smile when this small loose version of me camped out and started cracking around the garage floor with his favourite cars.

    Just had some very good used 260/610/16 Hankooks fitted onto the fronts. I'm moving from 290/625/16 and 310/650/16 Dunlops to 260/610/16 and 280/650/18 Hankooks front and rear respectively. While I'm giving up 30mm in width the tyre quality is night and day, these Dunlop's are really an 80s design tyre. Not very quick, fall off a cliff after a few heat cycles and spendy. Have had two mates now who are 2.5 seconds quicker on the Hankooks than fresh Dunlops. Oh, they're cheaper to buy and hold on to performance a hell of a lot longer.

    Bit more stretch on the 10" fronts, but I don't think the bulge of the dunlops was beneficial.

    Interesting. Same grip but less drag would even be a benefit.
    Lots of minis & mokes including a G13b powered Sports Sedan, a couple of Swift Gtis, a Goggomobil, Porsche 928S, Polo Gti, BMW 540i, a WRX and a few others.

    I decided to wrap the exhaust side intercooler and inlet piping in heat reflective tape. I'd like to spend a bit of time over the break on the heat management, some ducting from the front of the car to the wastegate (it's up the back behind the strut tower, gets no air flow and I've had 1.5 failures here), fire proof sleeve on the oil lines, wiring and vacuum lines. While I do want to go to a turbo beanie, I might see if I keep this turbo or upgrade it first.

    With the cracks welded up in the plenum/runners and the new CAS the car seems to be idling so much crisper and cold start is awesome given E85 & no ICCV. So it needs to go back to Scott to tickle the tune now as it was messed with when there were cracks in the inlet. Quick walk around vid, car hadn't been started in a week.

    Weíve had a couple of wastegate diaphragm failures that could well be attributed to the gate being behind the strut tower at the back of the bay, ie zero airflow. Iíve been perving at more and more turbo circuit car engine bays and noticing many are ducting cool air to the gate. Pretty good idea I thought so Iím now picking up cold air from the grill through the high temp ducting straight to the gate body.

    Hey mate, manifold was done a few years back. After many hours on the dyno itís just discoloured. Iíll probably wrap the dump pipe and gate dump and will get a turbo beanie.

    What compound Hankook's are you using ..............

    I'm on a similar (front) setup 295/625R18 with SS12 compound and was looking at alternatives. Hankooks in that size come in 3 compounds - C3, C5 and C7 - which did you use ??

    Scott (OKE020) @ Cleveland Exhaust gave it a bit of a tickle up on the dyno after installing a new Tiall 44mm gate. Once the plugs were gapped down some it sounded really strong and crisp. Sounded the best it has in quite some time. Ended up with 371rwhp on gate pressure (15psi), 387rwhp on 17psi and 439rwhp on 23psi. Total timing of around 21 degrees up top, it will take more and likely make more but the car seemed really happy there.

    I now need to make up a proper mount for the R35 coil packs as the the coil for number one wasn't aligned particularly well and has damaged the plastic tube. And some rear tyres and then skids.

    Yesterday my floating rotors finally arrived. 334x32, be interesting to see the weight difference!

    Also heading out late this arvo to Willowbank with a few of the PF crew. Looking forward to it!

    Well that was an interesting night out!!

    1st run I bogged hard core off the line, really tall first gear. Then got it going, was ok in 2nd, 3rd a little squirrelly, 4th it bagged them, stepped well sideways and I thought I was going to clout the wall, gathered it up into 5th and wheelspin. 13.3@121.6.

    2nd run I slipped the clutch more and didn't bog, changed into 2nd too early and bogged (getting use to first gear, so tall and you think you've run it out but you're just wheel spinning). Came onto boost and limiter with wheel spin, into 3rd wheelspin, back off into 4th, 3/4 throttle, wheelspin city back off a bit feed it in, wheelspin, into 5th, sideways and wheelspin. Back the fuck off fuck hitting wall at speed. 12.6@114mph.

    3rd run, bigger skid using 3rd gear. A combination of feathering the throttle lots and judicious use of steering wheel. Still wheel spin in the first 5 gears with more than 3/4throttle. 12.2 @ 120.9.

    4th run, left lane. Decent enough launch, change to 2nd at the perfect time, feed in full throttle. Grip! And *some* grip through 3rd, 4th and 5th. Shift lights gone off in 5th as I cross the line for the first time so I know the MPH is also decent. No time slip. The guys were working on the VK so didnt see the run. FAAAAAAAARK! Since hear that run was an 11.9, not sure on MPH yet.

    5th run, right lane again. Car turned hard in 2nd, got off it, back on it and shifted into 3rd. Went completely sideways, crossed into the other lane and nearly clouted wall. Fuck that noise.

    On the return road changed up into 3rd and it basically free revved. Back down into 2nd and same, with some drive. Tunnel hot as fuck. I'd been noticing clutch take up point was getting higher and higher, but it was still grabbing like fuck and not as if I use it on the up shifts. So hopefully just an airbubble or sticking slave.

    Ah well, despite car trying to kill me it was a lot of fun and beats sitting at home sinking piss.

    Paydirts brother saw the half decent run they didnít print the slip of, apparently an 11.9 at he thinks 125mph. Iíll head out there again sometime with some fresher rubber.

    Sounds like it was a handful and a heap of fun. Great time, considering circuit car.

    Put some mt's and soft shocks on the back and crack a 10

    Was a fucking riot to watch, plenty of oohhs and arhs as it went up the track all over the shop,

    There is that site or whatever I see people getting their times from if they run to fast etc, surely the run will be on there?

    cant remember the site

    So I got the car off the trailer this morning. Clutch take up is lower, not as low as it initially was but much better. Positive feel too. It's the spare clutch out of the Hammerhead time attack car, from memory 4500 pounds of clamp but its a single face sprung centre. It's designed to be driveable, in a circuit race you only have one launch and don't use the clutch on the up shifts. So it looks like I just over heated it with the 5 skids and 5 slipping launches in relatively quick succession. Fuck the tunnel was hot after the last couple of runs. The fluid is black too. So will give it a bleed this week and it should be right. Big tyres and a tall first gear, I was just asking too much of it.

    With regards to the tyres, that's just my naivety. I knew they were fucked but didn't really think it through. Even when they're fresh they take a good 3-4 laps at QR to come on, when they're fucked they just don't. Kind of silly thinking they will with a skid on a non-prepped strip! I run 22 hot at the track, after the first pass I dropped them to 16 hot, didn't seem to make any difference. Scott was off the thinking that it's wheel spinning so much it's actually not getting the MPH, makes sense as I just couldn't use full throttle in any gear.

    Anyways, it'd be great to get out there with the fresh rubber for shits and giggles, but, end of the day it's just not made for this kind of thing. I'd certainly not bother fucking with shocks and springs, as there's only so much the clutch can handle.
