Ke15 Ready For Classic Adelaide Rally 2007

[D.McKiggan]

Hi All,

 

Just thought i would update you on the final testing of our KE15 for this year. Just had it down at Four Performance at Parafield for its final tune and check. See one of the runs on You tube:

 

 

We ended up finding out that the fuel pump was faulty which stopped the 4psi of fuel pressure needed for webers. It was running at about 1.5Psi which shows up on long power runs with the weber fuel bowl running dry, this then started to lean out the mixture at the high end. This was fixed with new fuel pump which should now maintain the pressure required.

 

Bloody amazing what Dyno's can show when you are testing on them. The final power figure was about 105 Bhp at the rear wheels. Most importantly the torque figures were up about 25% from last year. We custom made our intake manifold with a intermediate plate which allows porting from both sides. When bolted up with location dowel's this all matched up perfectly. Another set of ceramic coated extractors were also used this year which should keep temps down.

 

Anyone out watching the rally in SA in approx 2 weeks time come and say hello.

Very nice!!

 

Good power figures too...I wouldn't mind that 5K in my car 8|

[ancullen]

WOW! - you're keen on it Rolla Boy!

 

Seriously though, that's a very nice power figure from the 5K. 105bhp is 78kW. My 4A-GZE only makes 87rwkw!!!

Thats an awesome figure well done. do you have any more pics of that manifold and the engine?

[D.McKiggan]

Here Tis.....

 

Pictures show the middle intermediate plate (full 1 pc intake/exh profile) and this has 3 dowel pin's locating them all in alignment. This allowed the porting to be done to both head and then intake/exhaust manifolds each seperatly. When bolted together it all fits for a perfect flow.

 

Also the fixed up fuel pump system with new pump ect.

 

Its all the small things that make a difference.

Another update......

 

Went OK at scrunineering. Found a few small things like no reversing lights working, no window washer tank installed and front indicator was not working. Nothing to serious to stop us getting approval to run. The car was then weighed in at 850kg's.

 

The drive home was interesting as i smelt fuel and the car started to missfire a bit. Pulled over and popped the bonnet to see that the fuel banjo going into the rear weber had worked out!!!. It was pissing fuel everwhere. So turned off and waited for the service crew to come with some washers to replace the lost items. Car fire narrowly diverted.

 

Then it was noticed that the changing of 5th back to 4th was still getting to be real difficult. So pulled the gearbox and replaced one of the internal syncho guides. Perfect now. Next problem was the A frame was making a "clunck" sound under hard accelation. Found some free play in the centre bearing location point on the diff. Fixed that one as well.

 

So if all goes well we should be on the Prologue approx 1.00pm tomorrow. Should get some good camera footage as i have just added another camera to the front bumper bar. This gives it the go-cart feel of being on the ground - fast. Will post this on U-tube hopefully tomorrow.

 

Hoping for a problem free event.

Oh and here is the office for the next 5 days....

 

Good luck mate, hope you have a good run. How does the a arm work on the rear , thinking of doing the same on my car.

 

Will your car be on display Friday night on gouger st.

Hi John,

 

Hoping to be there on the friday night. Not going to push as hard this year to the point of stressing parts & tyres. We had the Prologue today and i made Dad drive this year. He puts so much time into the car and i seem to have the fun so it was time to let him have some fun. It worked a treat with a slower than normal time being run.

You might ask is that bad? Nope, as now we are quite early away each day and not subject to stage closures, faster cars coming up & passing you mid stage ect.

 

Should be a good year. Just have to monitor tyre wear as coming out of tight corners today it is now quite easy to light up the rears. We cannot change tyres during the event or you get a 5 min penalty. Hope to see you at the party friday night.

 

The "A" arm is called a Lotus A Frame and acts as a tramp bar to stop diff wind up. Can show you closer friday but need to use rubber mounts for IPRA rules. We use a solid spherical bush in the centre which is a no no in IPRA.
