i am trying to save weight with anything that i do so i put some speed holes in the gearbox side cover,i am just waiting for my engine shit to come back from the machine shop ,i will post up some pics soon.
down sharon.
Cool speed holes!
Talking about collectors and such, I recently got a program from the US to calculate pipe size and length.
It gives a lot of info on primary AND collector length(n/a) but it seems design of shape,
is less important than length.
The program guy said that the spiffy style like you gave done keeps up the speed(perfest for turbo),
and increases low speed torque, and gives it a wider spread of torque.
Are you boosted? And what primary size will you choose?
What do you use to cut the pieces up for the collector before welding Westi?

when i got my heads flowed ,1 3/4 produced the best flow for the exhaust ,so i have started with that size in mind.n/a all the way.but in saying that it realy depends on the power out put and how keen i am to go fast.
as for the cutting of collectors,i can't give away all the tricks of the trade.
just kidding.
all you need is a square bit of rhs with a hole cut in one of the corners.it is hard to explain,i am going to make a set of collectors later today,so i will take some pic's for u

Thanks dude, that would be good, you're a hell-guy.

here is a few pic's of one of the ways that you can skin a cat(cougar)
start with some bent steel 10 to 15 degree's
ad one jig
rotate pipe till warm
lock into position.
use your depth gauge reader to insure that you do them all the same.
use thin felt ink applicator to mark a cut line
now you are ready to use the high speed spark thrower to seperate the unwanted material.
re insert wanted material into the jig that we had prepared earlier.
count your fingers before starting the even higher speed metal straightner
after completing step one,repeat 3 more times
now you are ready to use the slow speed multi tooth de buring tool.
if every thing has worked to plan this is what it should look like,so far.
finally we are ready for launch .place the pipes together ,and
we have a small rocket ready for take off.

Thanks for sharing the pics mate - I am a sponge for the "how to" details!
if i get a chance me and the boy's were saying if we remember that we would try to do a how to each week.
down sharon.
Now that is really clever-would never have been able to figure out how to make the jig-well done.Like the text with each pic as well.
i was trying to make it interesting for all.
i think i might start a fun' how to' guide
down sharon.
Great pics....and great to see the process...thanks for sharing mate. :thumb

Nice work Westi.
Thanks so much for sharing!

question time for dave,whats the most cfm that you have seen an 044 produce.with a 42 in 38 out
down sharon.
Man they fit together well, Mine weren't so good and needed a lot of filing and grinding after welding. Thanks for the guide, now I will knw for the next one. Do you start by welding the whole collector up and then work backwards? We did mine the other way and struggled to get the last weld in the collector. As I wanted it polished we welding it all up only taking the collector, then split it all apart and had it polished and then welded the collector.T54
C'mon kids gather round,
there's a new sensation hitting town,
It's moving straight, low to the ground,
it'll pick you up when your feeling down.
they are n/a collectors,slip joint.so they are realy easy to weld.
i do my turbo collectors a little different if they have to be welded.
i will see if i have any pic's.

Ooh, thats testing my memory!
Most stuff we flow tested with the manifold at least, and usually with the carb also.
I would have to guesss around 125cfm@10" @.600" lift
this is equal to...oh crap wheres my calulator with square roots!? Canaea find him!
To get it at 25", multiply by the square root of 25/10.
Same deal with 28".....multiply by the square root of 28/10 (28 divided by 10, square root the answer)
Flow at 25" is closest to possible HP if optimised, (I am miles off!)
Roger Crawford recently made 310 with 305cfm@25"
I am flowing about 280 to 290 on my two different combos.(making less than 230 (so far!))
westi wrote:That's mad Alan.
that's cool ,thank's.
i ruffed my head's out to what i thought might work.
i gave the heads to Pat Purcell to test ,and asked to see if he could get any more out of them.
we got 210 cfm
@600 is that ok.
down sharon.
i think i drove past your workshop is it near bryant st / fairford rd ? your work is insane keep up the pics when wil she be finished
?
show us your gates
hopefully she we be finished for warwick.
hopefully we will have done some testing before then.
down sharon.
you thought right,were on the corner at the light's.

That is very good.
Even if flowed at 28" pressure drop.
I think that is around what Rod Richardsons heads flow(depending on if 25" or 28")
Although his were flowed with manifolds and carbs.

mine were flowed at 25" with manifold's and carbys also
how did you go on the weekend,all was good i hope.
down sharon.
hi all,
i got of my arse on saturday and did some more work ,the only problem was that the downer car that i took the brakes off needed them replaced .so i was in at work until 2 am sunday doing brake conversions,but i must admit that is nice to spend other people's money for them.
anyhow ,here's some pic's.
it was good te see everyone in queensland had fun @ the drags,except for fat macca and morg's.
this is the brakes for the downer car,
now for the shitter,feels good to get her back on all four's
pretty cool .it looks pretty tuf,lets hope it all works well.
fingers crossed
down sharon.
Sounds like a pretty damn good set of heads you have there Westi !
Yes we all had a good week end.
Poor old Macca and Morgie are down a little, but they are very Keen and will be back on top in no time!

Westi, what are those brakes? I am looking at the brake situation for my car and am not sure what to do. IRS back, BJ Front. any ideas? T54
C'mon kids gather round,
there's a new sensation hitting town,
It's moving straight, low to the ground,

the brakes on my car are of a 200sx,i had them laying around.
brakes are like a good engine set up ,what do want from your them ,race, street.
one of the reasons that i have chosen these brakes rather than a full custom set up is money,the other is praticality,if i ever have a problem with any of the parts they are of the shelf and easy to source.
front disc's are falcon $100 each,the rear are 200 sx s 14 $80 each,caliper's are all 200 sx s 14 $300 the lot.
the set up on my car will pull a 1450kg car up quiet well ,so it should be awsome on an 800kg car.
tell me roughly how much you had in mind as a budget ,what the car weight is,wheel size and main use for the car,and i can tell you which parts you need to buy,then all you need is a local machine shop ,and your in business.
down sharon.
Good idea, and for interest sake you could upgrade to R32 GTST or GTR rear brakes easily too if you want more rear end braking. These are direct bolt ons for the S14 200sx. Cheap too because a lot of rice burner owners upgrade to better brakes and can't offload their old parts.
That looks insane, cant wait to see a body on it!
Any Updates Westi?
Love to know how hose brakes are going,
T54

yes for the updates ,i have been pretty busy,i will take some photo's tonight
down sharon.
i have been pretty busy doing all the litte nic nacs,finishing of brake lines,battery brackets ,etc,etc.
and the car can't be complete without more speed holes.
i had to remount the oil cooler the 4 link got in the way,so the next size down was fitted,no duct on this one yet.
i will take some more pic's on wednesday and we will hold a competition to see if anyone can count all the speed hole's.i Know i have lost count,
