Whifbitz Supra Build Blog

The fourth and penultimate round of Time Attack saw the team setting out on a number of firsts. It was our first visit to the infamous Cadwell Park, something in itself quite daunting given it’s affectionate nickname of ‘mini Nurburgring’, but even more challenging was the prospect of joining the elite in the Club Pro […]

Just finished screwing the rebuild engine together, all looking good, going to install it in the car tomorrow. I wonder what the difference is going to be now I’m using a stock crank again, be interesting as nothing else has changed. I did a leak down test when I put the head on and I […]

Looks like I’m going to be building a temporary engine to use for the next couple of months. I really want to use a different piston this time around as I’ve never been happy with the cylinder leakage we have found with the CP pistons. Heavy breathing at idle and leak down tests aren’t that […]

Just stripped the engine down and I cant see any other reason apart from the oil pump giving up and chucking its guts out the back of the pump and then being fired out of the side of the engine buy the crank. Everything looks ok apart from 2 pistons which have been hit by […]

Just took my undertray/splitter off and there is a nice big hole in the bottom of the alluminium sump and the worst bit a hole in the side of the block. Looks like from what I can see so far the engine is ok, all turns over and there aren’t any rods missing! Looks like […]

On a good note, my OS Giken Type X diff turned up today.

I had a nightmare at Cadwell Park. Had a good practise on the Saturday afternoon, all was looking good, great balance on the car and even my brakes weren’t giving me any problems. Time Attack on the Sunday, 2nd practise session, doing about 8000rpm in 4th gear and boom, clouds of smoke out the back […]

Also some hot Time Attack news, basically because Steve and I have been to fast in Club Class we’ve been bumped up into the Club Pro class. And the organisers have created a Club Pro rwd class which is great as we really didn’t stand a chance against the front running 4wd boys. It means […]

Quick update before the next round of Time Attack this weekend. I blew another turbo to manifold gasket at Brands Hatch so bought one of these Twinsturbo inconel T4 gaskets instead, going to give that a whirl, suppose to be bomb proof apparently. I’ve also fitted a master cylinder stopper to stop any flex when […]

Unlike the previous rounds, the team chose not to do a trackday the day before Brands Hatch as this is our local circuit, and the one on the calendar we are most familiar with having done lots of testing and trackdays in the past. Paul Whiffin’s car had to undergo quite substantial surgery following the […]

Well, my bad luck is sticking around. After the first session at Brands Hatch I noticed some blue dust on the inner wing, traced it back towards the engine. Took the cambelt cover off and the belt had a big deep groove around it as if something was rubbing on it. So took the front […]

As suspected there were 12 bent valves, all repaired and back together again ready for Brands Hatch.

The second round of Time Attack saw the team making their annual pilgrimage to Knockhill in Scotland. By far the most remote and distant circuit on the calendar, Knockhill really needs to be seen to be appreciated. The circuit itself is set in the picturesque hills of Fife, and is around 10 miles North of […]

Well, not that good news really. We were at Knockhill in the 2nd round of our 2010 Time Attack campaign. In qualifying all was going well, getting faster and faster and just about to turn up to full boost. There was a red flag so came into the pitlane and noticed it was running rough. […]

Quick update. We had a very successfull weekend at the 1st round of our 2010 Time Attack campaign, you can read all about it in the Time Attack Report section. The car itself performed very well with 4 seconds being knocked off the lap time from the previous year. The best part of the car […]

Following a long and at times frustrating hibernation period over the winter months, it was finally time for Garage Whifbitz to dust off their equipment in preparation for the 2010 Time Attack season opener at Oulton Park near Cheshire. Whilst both Paul Whiffin and Steve Linton had not managed any seat time in the cars […]

Finished off all the boost solenoid/wastegate piping. Done the whole lot in Goodridge fittings and braided hose, quite a few of them with the twin wastegates, took ages making them up. Then protected the hoses near any heat with DEi heat barrier tubing. Refitted the heatshielding to protect the master cylinders and the air box […]

Just got back from the dyno testing out the new Whifbitz twin wastegate/scroll manifold on my own car. All I can say is wow, what a difference it makes. Hits 1.6 bar about 500rpm earlier now and peak torque is about 1000rpm earlier, amazing difference. The changes that I’ve made are Before: HKS twin scroll […]

Also more or less finished my “MK2” carbon dash, well happy with the way this has turned out. I used some much thinner carbon this time and its all one piece and very flexible so easy to use and of course very very light.

Some of you will like these. Installed all of my Ikeya Formula rose jointed suspension, proper bits of kit these. Rose jointed toe arms, lower arms and traction rods. Also front lower arms which have adjustable roll centre positions which is nice for setting up the suspension properly, I’m hoping this will get rid of […]

Got some more done today. More wiring, plus I got part of the dash back in, I had this flocked a few months back now, so its nice to finally get it in the car. Also, I’ve filled the holes left by the glove boxes and air vents for a nice one piece look. Still […]

My replica Ridox carbon front splitter/undertray arrived today, check this baby out, also replaces the stock undertray so its effectively flat bottoming the front end. Hopefully its going to work as good as it looks.

A few pics of the titanium exhaust today. As you can see, its a 3.5″ titanium from the turbo back, which means super lightweight and its looks the business to. I’ve also gone to the extent of having the wastegate pipework made in titanium to, even the wastegate flanges, all these have to be made […]

I’m on a bit of a weight saving mission at the moment, I thought I’d get rid of all the sound proofing. Took advantage of the cold weather and most of it just chipped off, not a 5 minute job though, spent 6 hours getting rid of most of it. Guess how much it all […]
