985cc Turbocharged Nova Sprint Car

Car looks superb Colin. I'm sure you will get the bottom of the miss fire

In the post today I got a new set of spark plugs, a new crank sensor and a new coil pack.

The plan is to replace one part at a time to (hopefully) get this misfire resolved.

I've found that the problem does show up with the car sat still, if I rev it anywhere much past 6,000 it starts missing, popping and generally misbehaving.

This morning I replaced the fuel pressure regulator, which hasn't made any difference at all. I did dismantle the old FPR just to check, and all is in perfect condition, so it's no surprise to find this isn't at fault.

The new FPR has a convenient take-off union on it which I have plumbed my fuel pressure sensor into, and I'm seeing around 3 bar, so there doesn't look to be anything amiss there either.

Coil pack and plugs are easy changes, but unfortunately the crank sensor has been hard-wired, so that will be the last thing I try.

I've also got some new HT leads on order from Magnecor.

If none of these cure it, I guess it will have to go on a little holiday to BTEC Racing for them to run it up on the rolling road and plug in the OMEX laptop.

Not posted in here for while, but always check up on the progress. Got to say this has changed alot since I last saw it! Looks top notch though Colin, really like the new wide arches and colour. Are you planning on having any graphics put on it, or are you keeping it subtle looking?

Shame about the teething problems, pitty you didn't get to iron them out before race day, but it's always the way I suppose... Not enough time in the days and the unluckiness of having these things happen when you least want them too! Hope the new parts cure the problems, and keep us up to date with racing progress

That looks brilliant.

That looks brilliant.

Thanks, I'm really pleased with the way it's turned out.

If anyone wants an up-close and personal meeting with my Nova, they need to get themselves along to the PNG National Weekend! Booking closes soon, so don't miss out.....

Just got a CD through with a bunch of photos from last weekend's racing. There's a lot, and they are big files so taking a long while to upload, but here is the first batch;

So much like a savage little RC car!!
Guess thats a good thing really!? Looking very light and nimble even just in the great action pics,cant imagine what it must be like!

That looks awesome Colin, good work, hope the misfire issue doesnt take too long to sort, sods law says it will be the coilpack, annoyingly as thats the bit thats not so easy to change

I hope it is the coilpack, that's really easy. It's the crank sensor which is more difficult. To be honest I'll be delighted if it's any of the ancillaries I can easily replace, and not something more dramatic (i.e. inside the engine!).

Looks awesome in action colin, really looks the part.
