tbro's 2nd NA, Scooter's resto

[tbro]

By the way how close does your DB bar go towards the roof, mine seems to touch it??? Strange.

My BD rollbar touches the hardtop and soft-top. They've managed to rub off a bit of the powdercoat in the outer corners of the rollbar. It seems there is a bit of variability in the rollbar sizing or in the way they're fitted perhaps.

Thanks Bryan,
I wasn't sure if the bar had been spaced up but couldn't see anywhere that it had been, and with the bar padding in place it made putting the softtop up an absolute PITA.
I'll trim down the padding when I fit the top on as I may just fit the fixed plates from Miata spec cars, to stop it getting pinched.

I see some fun parts in that photo
These would make her no fit 2f again

Hope every thing going well for u mate
Is scooter coming out to qr in April for a play
Oh do you have any wheels and r888 for sale

Hey Rob,
AH!! the rules say I can't fit "a" turbo or supercharger, well I'm not. I'm gunna fit 2 turbos. Wanna see the faces on the scrutineers faces when they open the bonnet!!!!!
And how do ya recon some 2B drivers would react Stirrer? where? me? naaaaa!!!!

As for me, hopefully results will be back tomorrow and good news it will be, but if not I'll keep on keeping on
Playing in April at QR, do you mean the MX5 track day, I don't think I would be too welcome, I've had my say and I think that would be enough.
Wheels and tyres for sale, just got rid of some old 888's. Try Mike with the totaltools car.

What happened to you and Morgan Park? Did you run or not. From what I hear bit of biff and barge last race?????

[rwf]

i would go black hard top they look great ah

fingers crossed for you mate

Hey all,
Haven't done a hell of a lot to Scooter lately, just lots of figuring reading and experimenting etc.
Our calculations have led me to doing away with the Stewart intake system and building a different system all together.
Its amazing what a hydraulic engineer can work out with the right info and programs.
So this is what I'll be running with,
the start,
the middle,

and where it finishes.Still have some shield to make and fit and a bit of moding to the engine cover.
Has definately cleaned up the engine bay

Even changed the Variable TPS to a simpler unit, so will have an auto TB and new variable up for sale soon!!

It is quite surprising how much difference that added or reduced length will affect the output of the engine,(one advantage to working on a Porker GT2 racer, ya get to look at what the factory do) and how much cooler the AIT has come down.

Won't be coming here much for a while as I'm going in for a oil pump repair so keep out of mischief or don't get caught.
And Bryan, stay off the walls mate, I need ya up here for the Nationals
See Ya.

Nice work on the intake Terry. Can you post up some data on the intake temps? Maybe a before/after dyno run too?

And Bryan, stay off the walls mate, I need ya up here for the Nationals

Mate, I reckon my chances of getting up your way this year are now somewhere between "none" and "bucklies". Fixing the bimmer after that one momentary brainless act will cost me the equivalent of a full year of trackdays in the NA6.

See how next week goes and we'll work out something

Ok, I've decided I'll use this space to try and pass on some info I've gathered over the years.

http://www.camsmanual.com.au/ use it, think about it and then reread it, this is a legal document, it is open to interpretation and not everything is black and white. BUT make sure you have a convincing argument if your gunna try something too far of the block.

http://www.bmsc.com.au/forums/rallying- ... orums.html, interesting stuff.


Some of the best reading I've come across for helping to set up your car and the whys and wherefore it works and doesn't. Great for novices and pros.http://farnorthracing.com/autocross_secrets.html

Books that have helped,

Speed Secrets & Speed Secrets 2 by Ross Bentley, there are a few in the series ,I prefer these two.

How to make your car handle by Fred Pugh?? an old book but very informative if at times a bit heavy. Remember, suspension is nothing but compromise on a production based road car!!!! even a GT2 or 3. And a sway bar cannot work properly if the linkpins are not straight up and down as per the factory!!!!!!(think about it and how to get around it, look at the pics)

Track Data by Craig Pearce, avail in ebay.com. Cheap as, as the list are something that we all think we should do , but never do. ALWAYS in the transporter and my suit bag. BOAGS and Crewman should really have this book.

A few things to think about BEFORE you start to play on your car.

Do you have the ability to do the job and the ability to ask for HELP when the sh*t hits the fan???

Just because everyone else does it DOESN'T make it right or work the way they say it will!!!!!!!!

Dynos do lie, use them to guage on % of improvement, but your best dyno is track times and PBs.

If it doesn't say you can do it , you can't. Seeming a quote from CAMS. I've never seen it written in the book, and if we go by that theory no-one will ever try anything new, so to me a load of Crap!!!!! But again stay within the gray areas!!!!

Enough for now, I'm getting tired (POB)

Seems Danny and I post around the same time!! after big gaps.

Update on Scooter.
Were do I start, finished building the new motor and had more head work done and finally put her on the dyno. Started pulling some good numbers then went further and after stuffing around with regulators was pulling hp figures just off the GP car and Millers car(same tuner same dyno). More than happy with that but we were running too close so backed it off. Fitted some bigger injectors, fitted a higher capacity fuel pump and back onto the dyno. Ended up down on what was available but with 5% over-fuel for the 1 hr at Morgan we were happy.
Then someone did what I asked them not to do and I ended up with a no go.

So I spat the dummy and put him up for sale. Lots of if onlys etc, then Nicky and Wendy asked me not to sell him and to do a rebuild.
I got in touch with Lou and purchased a NB motor and then Andy offer his motors up so I bought one off him too!!!!
Did a bolt down on Friday and dropped off roll bars and my old engine and bits and pieces, picked up the 2 engines and headed home. Nicky and I arrived back in Brissy Sunday, unloaded and stripped the NA motor.

So now I've got a block sitting on a stand, a head going off to the machine shop after I finish off the ports and chambers.I've ordered new valves, followers etc. The new rods etc arrived so their together with the pistons, and every thing is going down for a balance when I get some more mulla.
Working out the compression ratio at around 12.6 to 1, may need to drop that down a bit me thinks.So it will end up very close to the B6 build, Supertech 11 to 1 pistons, M Tech rods, ARP bolts everywhere, ACL bearings everywhere, gates belt, Bell Eng oil pump, head work and port matched manifold, bigger injectors, Toda flywheel and pretty pink clutch kit Cams are a bit of mystery atm, gunna wait until we flow the head and fit the bigger valves then Roy can work out the best cam grind to do to suit this engine. Hoping to secure a set of Racing Beat headers that have been coated.Then once all of that is finished back on the dyno again. Now I need to save up my pennies,sell the NB motor and try and keep in good health ( less stress would probably help) and I've now learnt if your gunna lend your car DON'T






So I'm running the NA motor so I can stay in 2F, if I want to I can go to 2B if I want to run slicks.

Quick question, WTF is the fuel reg on a NA8 fitted and is it normal that the fuel rail has bolt on fuel pipes or should it have slide on rubber lines?????

So now Scooter will see track time but maybe not as much as a race car more a track day special.

It is like deja vu looking at your thread , pistons, rods, shiney ports, but you are getting things together much quicker.

Love the work, can't wait to see how many ponies you make.

[sailaholic]

Fuel reg is on the front of the manifold at the end of the fuel rail. Hoses are rubber slip on front and rear. Let me know if you want a photo.

[Steampunk]

Fuel reg is on the front of the manifold at the end of the fuel rail...

It is on yours but not on the original fuel rail.
Tez the FPR is toward the back of the engine, pretty much in-line with cylinder #4.
As for fuel pipes, from memory, there are short hard pipes at funny angles welded to the square-section fuel rail. The only bolts I remember are the two attaching the FPR to the rail.

[sailaholic]

Doh! didn't even consider they might be difference. Thanks for the correction

So ok thats for that info, should of had a closer look instead of a quick gander.
This is what I suppose you call "the fuel rail mod", I thought you drilled the end, left the reg in and silver soldered the fitting to the end rail.




So I've ordered a Sard rising rate fpr. That should sort that out. Might even fit a cooler along the rail on the return line as the fuel get pretty bloody hot, dunno, gotta think of that for a while

Modded the sump a bit,


even ready for the day I fit one of those things still sitting on the floor!!!!!


OH well out to play some more
BTW, Si am I an aunty or uncle????

Terry

[tbro]

Major parts have now arrived and after filing ring have assembled rings to pistons.
Bottom end now sortof together

Fancy bolts everywhere, Don't ya love the safety boots!!!!

And pretty bent pipe type things, all silver too


One very well made extractor system.
And yes, that NB motor is for sale cheep cheep!!
Going to run oil catch can to feed back to motor on this motor, the plug is there so might as well use it!!
Have pulled sponsorship from a Mobil distributor so looks like I will be a Mobil 1 user
Cams I'm still thinking about and I'm waiting for some emails from the US, the price of cams here are too bloody dear and most won't do new blanks and when they do & I'm not one for fitting spacers to hydraulic buckets to correct poor machining or design.
Might even run stockies to start with.
So I'll be wiring up oil temp and water temps up today to start with,
and then off to get some fuel rail fittings etc ready for the big install, hopefully next weekend, maybe !!!!!!!!

Terry

[Dweezle]

Looks fantastic as always Terry!!

[tbro]

Thanks Mark,
Trying to set myself a standard It's called being a silly old Fart

As I'm still waiting on bits and pieces I decided to fit and wire up the new guages, a water temp and an oil temp guage.
Only cheapies but will do the job, provides just that little bit of insurance (if you actually look at them)



Drilled the cylinder head for the extra sender,

Plus a blingy fpr, bit gory looking but if it does the job !!

Now just need to make up a fuel manifold for the inlet, silversolder up the fuel rail and then I'm just that little bit closer


Hopefully the valves will be in this week so I can finish off the head.
I'll keep ya informed
Terry
