We are now also using a 245 Kuhmo Ecsta on the 9" rims which despite being the same size is physically small and seems to roll less

Hi Steve,

As what Andrea was asking, what size sidewall/profile are the Kumhos?

[ZCars Steve]

245/50 13 like the AVON CR500?

I have just checked the Kuhmo size they are 235/45/13 and in stock

[andream88]

I only have 245/50 13" on my italian V5!

How much for a full set of Avon cr500 in 195/45 13 fronts and 245/50 13" rears? In stock?

Oh OK, I thought it was a new size just been brought out my Kumho, I was already aware of that size. I get a discount of Toyo's so will probably be sticking with them purely from a cost point of view.



I put this table of R13 track day tyre sizes together for my own use but figured it might be of use to others -some of the info I could not find yet, if anyone can fill in the blanks it would be appreciated:

The AVON CR500 are also available in 195/45 13" and 245/50 13" which is what i'm currently running.

[cptkirk]

Updated, however I cand find any informaiton on the Avon site for CR500's in a 195/45 size????

[andream88]

Ouch. You're right.

Seems like they have been deleted from the list during the last few weeks.
They were listed 1month ago when i enquired for a set.

Mmmm, Steve??

[ZCars Steve]

Hmmmmm not sure I only ordered some a few weeks ago I will give them a call next week

[andream88]

Please let me know as i need a set

CHARGECOOLER ORDERED

Oh yes, my need for more power has at last been quenched, well the thought if it has as I have no idea exactly what numbers it'll put out with the chargecooler.

I am having the chargecooler cartidge made by Bell Intercoolers in the good ol US of A to my design. You will see in the pictures below that the unit sits between the charger and the intake manifold. Fingers crossed I got the design right - ha ha - only time will tell but its not that hard to do with the modelling of the charger and manifold I did last winter. I am hoping to get my TB-SC manifold finished this winter also so the gains should be pretty good. I am adding a snout clamp into the mix to hold the snout of charger firmly in place as it'll be using more BHP to spin it and it'll be spinning faster, this will remove a lot of stress from the bolts holding the intake manifold and I am looking to beef up the support under the intake manifold also.



So here are a couple of views of the intercooler unit as I designed it:










And here are a few of it in situ with the new TB-SC manifold and the 72mm Throttle body (both of which didnt get fitted earlier in the year):




















As i get the part delivered I will get photos and update the build diary, I dont want to guess at final horsepower yet but cant wait to get it dyno'd in the spring - Whoop whoop.......

Top CAD work there makes it much easier to see how you are going to get it to all fit together.

SPRUNG EXHAUST FLANGES

I have been suffering with lots of exhaust fumes in the cabin of the car which I can only put down to the sprung non gas tight exhaust fittings that are used on the exhaust system.

So I got my thinking cap on and what I am about to show you is the 5th revision of the design. I modelled one of the headers as thats all that is currently required and their compound angles are tricky to model so I am saving the other header pipes for a rainy day. The two Y-pipes as I am calling themn the 2-1 Collector, the Silencer and finally the Tail Pipe.

You might think this over kill but I had to model the whole thing so as make sure there werent going to be any clashes between the header flanges and the silencer.

I first considered amking the flanges solid and adding a flexible pipe to the mix but that wasnt going to happen due to the diameter of the flexi pipes. I was also advised even though I have pretty solid engine mounts that solid flanges would fail as the vibration would shake the thing to pieces.

So this lead me to think of sprung joints but also with a flange, still utilising the pipes sliding into one another. Then I had to work out how to use the least amount of bolts and springs so as not to over-do it. I had to consider how to ensure that all plates were being held using only four bolts per set of flanges - cracked it though.....

So the .dxf file is off to the laser cutters and I hope to have them in my hands fairly soon.

As always here are a few renders of the work:























Some cut through views to show the pipes slid inside one another:
