Trident 3 into 1

Stuart SS · Sep 2, 2012

Ahhmm

As I am currently travelling the rocky road of carbs and even exhaust particularly related to my own T150V ~ and as I have considered the T120 Mufflers on mine currently ~ the issue of lack of back pressure/s has been thrashed - yet again- ~

I ask would a 3-1 as referred to herein ~ so many are race bikes ~ is this what you are looking for ~ Is it an issue?

As I see it and have been lead to believe, some of element of back pressure IS an issue ~ But as I see it back pressure at low, bottom end is not an issue !

In fact my T160 when I sold it ~ the buyer asked why the bike woudl only do 95 mph ~ (the fact was that the Police officer that bought the bike boasted he was bound to be the gentleman rider, never stretching or thrashing the bike ~) ~

I suggested that the custom made copy black caps were a concern even when I fitted them as the actual caps were obviously far too restrictive at speed!

And if THATS not a 3 - 1 , These ARE 3 - 1 s. 8)

My thoughts are that tight bends dont do what open bends , usually seen on BSA's Do .

GREAT photo! Do you know the venue?

It's Daytona 1970 I thought....

Nah, them's milers, dirty flattrackers, before H-D had the AMA BAN more than 2 cylinder racers - have another view of On Any Sunday, you can sure pick them 3s.
As for back pressure, the less the better, uncork`em, & as Matt has pointed out previously, the original 'Ray-gun' mufflers were stylised fish-tail megas, gave best power for production [although I`ve never seen a Hurricane dyno chart], but open works best if volume is not an issue...

Nah, them's milers, dirty flattrackers,

I agree in hindsight ~ No front brakes ~rugged tyres ~
I have seen this photo many times before ~ I did some searching this morning before work but have not nailed the details ~ as yet ~

J.A.W. · Sep 5, 2012

Bike mag tested a Hurricane in `72, got a 13.3 sec 1/4 mile, anyone know if the 3-3 pipe set up lost power anywhere?

Matt

heres a pretty one

That Rob North belongs to Steve Robins Aka 'Snibor' across many sites ~ in Brisbane, QLD Aust ~

I have even slipped the left leg over this very bike ~ The small size of the bike is stunning. it is really compact and this photo belies the size of the bike ~

Steve has only the kick start and I can assure you that bike does bite ~ Steve runs 11:1 CR

Here is a link I recorded last year `

Here's Steve's '74 Trident with 3-into-1, from my late friend Malcolm "BritBodger" Dixon's estate, sitting in my garage 'till he comes to pick it up in 2014 during the BSA rallye.

Another good mates Trident T150 with 3:1

Cool, can you post a Hurricane 3-3 clip for aural comparison?

Stuart SS · Sep 8, 2012

JAW

YOU ASKED FOR IT !

This clip is ^%%*&&^ AWEsome ~

Turn up the speakers ~ be aware though any non Tripler fans amongst us may just be converted !! FOREVER !!

[video]http://www.youtube.com/watch?v=-f_FPjfBrWw[/video]

(On the down side ~ Mate, Steve aka Snibor has one of these and he reckons he has to wear ear plugs as the fuel tank is so narrow the tappet noise which 90% of triples are renowned for ~ is deafening as the engine protrudes so far past the actual tank!! With that in mind he prefers the Rob north as his commute bike!! )

Actually I was talking with TTRest aka Garry in Brisbane yesterday after my successful test ride on the Trident and he was saying ~ which I well was aware of ~ that the Triumph BSA factory race bike mechanics spent a LOT of time cutting and tuning their 3:1 zorst systems and they made it into a fine/ precise art ~

Great S.S.S., Ta.
From Classic Racer Mar/April `12 , Don Castro feature, P.43; Re those miler Triumphs:
"We were turning those Triumphs to almost 12 grand, & it would run from 2,500 all the way up to 12,000."
Carillo built his mills, including the rods, naturally..

Hi
I suspect the quoted 12000 RPM may be a tad overstated .. a bit of tongue in cheek perhaps

..

It’s just not possible to spin up to 12000 with the valve gear and geometry on the triples and would be pointless
as Max HP even on extreme tuned 750/850 triple engines is around 8500RPMbut will still flat line at Max RPM to about 9500RPM .. on a stroker quite a bit lower revs for max HP but bags of torque on a stroker..

here's a clip on the Dyno of the Manx R3 we had over the island this year ... not a silly tuned engine ... specifically built to withstand the punishment of the mountain circuit .. produces 87RWHP at 8250 but carries 87RWHP right through to 9000RPM and beyond i would think but 9000 is plenty on a dyno and scary as buggery to listen to ...
