Hey datodude,
it doesn't seem to make sense but it is true. We were constantly chasing a high rev misfire at the track and through past experience we generally suspect any tacho (usually aftermarket though) if an electrical problem arises. It felt like a rev limiter was installed - the car would rev up to about 6500 - 6800, misfire a little, then struggle on up the rev range with small, intermittant misfires. Came off the track, disconnected the two tacho wires and plugged them into each other to reform the loop and back onto the track. No misfire up to the "I think she's gonna blow" max rev shiftpoint. Regardless of logic, all these components are 30 years old now and like all mass produced items, can be prone to problems maybe even from new . If all else fails, try the tacho. Cheap to check - disconnect and then test (on a closed road by a professional drver under controlled conditions of course ) If problem persists, reconnect tach and move on to next suspect !
Hope you find it.
Cheers

Hey NZ,
do you run a tacho ? Electrical mysteries are often supplied by tachos ! I too had a mystery misfire in my coupe at the same revs and it disappeared once I bypassed the factory tach - must have been acting as a rev limiter!
Good luck.
Cheers

As with any rollcage, be it bolt in or weld in, make sure it is mounted correctly. If it is bolted to nothing then it does nothing!!
I have seen cages placed in a car and then the underfloor sandwich plate tightened until the floor is deformed up to the rollcage. . Make sure the floor is sound,the mounting surface level, and the load is spread over appropriate sized mounting feet. To get any real stiffening benefit, you will need a welded cage that is tagged to both A and B pillars. A bolt in will give you some roll over protection but little in the way of rigidity. A lot of movement in Datto front ends comes from the strut towers, the brace inside the front guards and the underfloor chassis rails at the front. Your biggest noticeable gain will be in this area I think.
Good luck with the project.
Cheers

I'm with Datt Matt. I too feel that power / weight ratio is a good idea for bikes and the new bike licensing scheme is a step in the right direction. Should have a similar system for cars. No one or no Gov't program can eradicate the "invincibility" of youth and the hormone fuelled bravado that comes with it. Testing the boundaries starts as a child and accellerates through teenage years (some adults never grow out of it !!!!) so some kind of guideline has to be in place.
My biggest gripe is driver training. Most uninformed adults claim driver training inspires teenagers to drive fast - because they have never done a course. Defensive driving is required, not race craft & heel + toe !!! What I have learnt through two BMW advanced driving courses, Peter Finlays race driving school and a recent Superbike School is that I was about half as good as I thought I was !!!!!!!!!! Learn the skills that will save your life ... collision avoidance, wet braking, planning ahead etc. One of these courses gave my brother the resources to reduce the severity of an accident when a small truck ran a stop sign in front of his 44 foot semi. Police acknowledged that without the manouvres my brother undertook, the passenger in the small truck would have been killed instantly.
In summary,
Basic defensive driving courses mandatory
Ban on high HP cars for under 21
Advanced course certification BEFORE you can purchase high powered cars regardless of age
More police presense on road, not revenue cameras or hiding in bushes.
But will NSW state gov't be able to function without all the extra revenue? Hmmm, I don't think we will see any initiatives that will actually COST the gov't money so I suppose it's just another case of lower speed limits and even more cameras !!!
Cheers

Hey Drift,
the bad news is ... the axles have to come out !! Not difficult but Datsun didn't really think about this when they designed the brake backer as a bearing retainer .
I have a welded H145 centre + housing + springs with lowering blocks that I took out of my coupe - going cheap. PM me if you're interested.
Cheers

I agree it looks the goods. This is his second attempt at selling it on ebay, the first buyer didn't come through (or sometimes a phantom bid by a friend just to kick the auction along ) and now it is relisted. If I was closer to needing a motor for the new racecar I would have a look .......
His description however did say it was rebuilt a couple of years ago so you would have to suss out the seller to determine what kind of "driving" he would have been likely to subject it to . Would be a no brainer for $800 - 850 !!!!
Good luck
Cheers

Hope you can run on Sunday - the more the merrier ! Met Craig Torrens at that hillclimb, from what I remember he is a top bloke. Don't know the others though. I'm surprised to hear they are all legit as 2 + sec is a lot at any climb considering the bloody things don't steer around corners !!
Glad to hear you had a good time.
Cheers

B310,
did they run 0 - 1600 or 0 - 1300 , 1300 - 2000 ?? Real disappointing when you have to run against the 2L cars Were there any of the 2L ( ha ha ha ha 2L my foot !) VW's there this year ?? Last time I raced at Bathurst the VW's were 2 - 2.5 sec quicker than the rest in 2L ... hmmmmm.
Glad you had a good time
Comming to Oran Park ?
Cheers

Supersprint on Sunday 12th. Run by NSWRRC Ph 4648 5922. Would be close to full as it is the last of the year. Enter, or come out for a look - either way at least 2 Dattos will be there
Cheers

Thanks Dodgeman,
fast - ish but never fast enough !! Goes okay for an A14 though . The benchmark for under 1600 is Chris - so that's my goal. A long way to go to match his times but one day ........
We'll see this weekend at Oran Park if I've got the goods, see if I can give Benny a shake up on the track .
Cheers
