So I fitted a set of Michelin Pilot Sport 3 tyres on the 9th month of 2017. I was well impressed with the tyres as this was a big step up from what I had on the car. They were very grippy in the wet and the dry. This was just out and out an awesome tyre. Fast forward 3 years 8 month. I have done 40000km on the Pilot Sport 3 tyres. I rotated the tyres on every service. I had one repair done on one tyre due to a screw I picked up about 3 years ago. The tyre was never flat, I just had it checked out and they had to do a repair as it went through the tyre. Luckily the tire was still on spec pressure when I brought it into the tyre shop.
I noticed the front tyres started flaking and pieces of rubber were being ripped out. I also notice some cracking on the tyres all around. I took the car to the shop where I fitted these tires for inspection and they said the tyres are not dangerous like that. They asked me if they could rotate the tyres for me and just check the wheel alignment. I said yes, and they put the car on the lift.
Once the wheel was off the car they called me and the one front tyre was split open right around on the sidewall. How long have I been driving around with this tyre I don’t know. Al I know it was really dangerous.
Here is a pic of the tyre that split open.
Has anyone seen something like this?
I will write a post on the main site about what the outcome was with this tyres.
I think you are going to battle to find upgrades for the VK45DE engine. Anything you do to that engine will have to be custom parts. If you are looking for rods and pistons for that engine you can maybe contact Cosworth in USA or UK as they may be able to help with custom parts. The easiest way to make good power out of the VK45DE engine is to supercharge or turbocharge it. If you run 0.3 to 0.4 var boost with a supercharger you can get about 450Hp on the crank. More than that boost and you will bend rods. You will see in my blog posts the I have pushed a VK45DE to 700Hp and 850Nm torque just by lowering the compression of the engine by machining the heads and pistons and running a 3.3liter/rev supercharger.
Hope this helps!
Hey Brett,
I know I have pics somewhere, will have a look around and post them as soon as I find them.
You are welcome to post pics and memories as well!
2012 was a hectic but great year, I miss all the action!
Hi Mario,
I should have the 3D CAD for the sump. I can put you in contact with a company that does CNC work here in Cape Town. They are the only company that I will supply the CAD for the Sump as I do a lot of work for them. The Company is ABR Engineering. You can speak with Harold Bannister (Cell: 083 446 0675) or email him at Harold@abrengineering.co.za to get a quote on machining the sump.
Hope this helps!
Hi Mario,
Everything looks great so far. What is your plan with the drysump on this engine? What drysump pump are you going to run? Will you be running a proper drysump pump which will have the pressure and scavenge pumps? The motor we built for the Porsche 917 had a drysump on it. We took the standard pump out of the engine and run a Moroso 3 stage pump, 1 pressure pump and 2 scavenge stages. I designed the drysump for the Porsche, and it was machined out of billet Aluminium. You may have read this post but here is the post that has some pics of the drysump https://crasyideas.com/race-car-560hp-supercharger-vk45de/
Hi Mario,
This looks like a very interesting project. How long have you been busy with this project and what is your estimate time it will be running? Please post some more as the project goes on. Will be great to follow the build.
I finally got a resonator delete pipe for my 3″ Scorpion exhaust. It sounds insane. The popping sounds that usually go with a big exhaust is now audible. The next thing I want to do is install a button on the car so that I can disable the exhaust flap from inside the car. I don’t want to disable the valve permanently. On normal driving, I want the valve to function so that the noise inside the car is minimal. When I feel like a bit of spirited driving then I can switch the valve off and enjoy the beautiful noise. I should have bought the Non-Resonated system from the start. I would have saved a bit of money. The Car really sounds brutal.
I have a friend that does high quality fabrication, and he is going to build me the resonator delete pipe for my 3″ scorpion exhaust system. I don’t want to cut on the current setup. Because the Scorpion exhaust is modeler, he could just build the section to replace the resonated pipe. If it turns out to be to loud I can always just put the resonated section back. The pipe will be built next week so looking forward to it. Will post once it is done and give my feedback on the non resonated Scorpion Exhaust system.
