Getting ready for IVA at Daytuner

Had a call from Damian at Daytuner today who told me that he was having difficulty in mapping my engine for emissions. The car is fitted with a cat and exhaust but was refusing to provide a consistent emissions readings.

Damian has completed compression tests on the cylinders and found that cylinders 1 & 4 are 210 psi and 2 & 3 are reading 190 psi. Given that the engine is supposed to be fitted with high compression pistons, these should be reading of closer to 240 psi. 

He also completed a leak down test which showed up a problem with the piston rings and a small amount of leakage via the valves, this can be fixed by seating the valves with a grind. I'll do this sometime in the future.

The other possible issue is with the high lift kent cams that are fitted and the possibility of valve timing overlap. Damian will swap out the cams for standard ones tomorrow and to try again. 

Hopefully he can sort the emissions and get it down to an acceptable level. IVA is booked for 8th so will need to let them know by Thursday if I need to postpone the test. 

Blyton Park

Had a day out yesterday and met up with the MNR team along with a decent turn out of MNR owners.

Experienced some track action as a passenger with Leon in his MNR, he drove it like he'd stolen it!! Nothing came close, even full blown race cars at 3 times the cost with downforce.

Later on he hit a cone while not paying attention, he was checking out his dash and he bent a front wishbone, lost a cycle wing and damaged a rear arch. MNR sorted him out and replaced the wishbone at trackside and got him back on the track. Surprisingly they had a set of wishbones on the trailer, guess they have been here before.

There were some really great MNR's at Blyton, one that I was impressed with was a tidy grey and black car owned by Chris, he's done a top job and has given me some ideas.

Like his Tillett seats, they are comfortable and look amazing. Will look in to getting a pair of these when I get my car back from IVA. Also like how Chris has fitted his diffuser, his rear  brake callipers and the 0.7mm carbon used on his boot lid. 

Still Waiting For IVA

Chased up VOSA in Swansea today and they told me that the documentation was in order and they had had passed it to the local testing station in Beverly on the 4th September.

Was told that the station should he in contact within a month to book an appointment for the IVA test!!!

Called the Beverly test station and they have now booked the car in for 8th October for the test. 

Spotted at MNR

My car was finally collected by MNR on Tuesday this week and taken back to Harrogate for IVA prep, then will go to Damian at Daytuner for mapping. 

Received confirmation from VOSA that my paperwork is in order and the Beverly Test Centre will be in touch with a date. Hope it's soon as I've been waiting to get IVA sorted for a month now...

In the meantime, here's some pictures of my car at MNR.

Differential Options - 3.14 or 3.38

 

Had some debate about different differentials fitted to the Hayabusa and the difference between a 3.14 & 3.38, used a sheet from online to calculate maximum speeds in gear. The calcs are based on a 11,000 rpm rev limit and 195/50/15 wheels and tyres.

By changing the settings on the sheet I calculated that in 6th gear, 70mph on the 3.14 is 5,500rpm and on the 3.38 it's 6,000rpm.

3.38 Differential

Waiting for IVA

All done now, waiting for a date for the IVA test, MNR will collect the car to set up the geometry and then the car will be off to Damian at Daytuner for a rolling road tune. Will be interested to see what power the RPE engine makes.

MNR will check out the car and then take it for IVA, just waiting for a date now....
