The problem is gonna be what size is the sender? The suzuki cap screw 'cover' is M14 or M16 and once you bore and tap the centre out
you can't tighten it! May be easier to swop it out for a normal hex bolt and a dowty seal / washer and put the sensor in that?

Whats wrong with good 'ol fashioned scaffold pole crash bars - crash - bend - straighten - race!

Not wanting to get into a pissing contest but that's the first time I've ever heard anyone call stock studs 'precision machined items' - If your lucky they are forgings with a rolled thread so hardly a precision operation! Clamping pressure comes down to area and torque - APE studs and the stupidly thick bolts used in Busa motors these days have probably 50% greater cross sectional area each step - stock GSXR - APE GSXR - APE Busa allowing respectively greater torque to be applied to the nut / stud combination! Not unheard of busa's with 6-700hp @ 2.5 bar boost using 90+ ftlb torque figures to survive!

Because you combustion chamber CC number is -304cc which will in effect give u half of fuck all lol
LOL - rubbish in........rubbish out!

Nice one Arttu - looks a good bolt on solution for the Dino motors!
-
Thanks!
Got really good help from u guys!
Microsquirt seems exactly what have been looking for...They have 36-1 twheels allso but smallest seems like 4". Will täke a look around to find something smaller.
BR.
Triggerwheels.com or .co.uk do a 50mm dia one!
-
They are usually paired up with a 36-1 tooth wheel - heres a pic of that type of wheel on a GSXR so loads of space in a GSX cover and it'll use the std inductive pick-up!

Never used one of these nor have any product ties but as a ready built budget ecu with support - what's not to like!

I take it that some of the internals don't take turbo power to well then. What would the crank need to take the load.
New bearings, fully welded and straightened - ideally dowelled as well + the straight cut primaries!. Easy way to spend a grand!
-
Pretty piss poor instructions full stop and its not waterproof - not a good thing on a bike! Quality costs - how much do you want to spend
and bearing in mind the application, it's going to need all the help it can get!
-
Oil pressure and modern turbos! Plain bearing turbos will not survive with std GSX 5 - 10psi pressure. Has to be increased and even with 750 gears the 30psi is marginal based on turbo specs. Ideal would be to use a BB cored unit - more expense though! Rajays still work well on draw through installs - harder to find these days but the bearing arrangement suits low aircooled oil pressures!
-
do you actually have a death wish? Lol
No just a bloody good gear based boost controller LOL!

No build thread - was featured in Streetfighters mag - was built a fair few years ago and had a Mitsubishi hybrid turbo when they were 'state of art' - I'd deffo have a BB turbo now. It never achieved the target it was built for so there is more if I can get motivated again!
-
Turbos are relatively soft on rods and generally its lubrication failure or deficiency that kills them so that is the one critical area to make sure is right! And yes phill106 it was a big money build and well into 5 figures - mostly not by me happily!
-
When one of mine got a crack in the fitting to core I did find someone to weld it but the guy wouldn't give any guarantee of success as it'd always be a contaminated weld from the inside - always leaked a bit thereafter so I had to replace it! Sorry - probably not what you want to hear!
-
Just out of interest do the 1052 rods have 20mm or 18mm pins - think I know answer but asking anyway?
-
Picture and personal experience stated - seems conclusive!
-
This convince you ............
As they say 'A picture speaks a thousand words' but still confused as a few have been done with turbo builds and they appear to be low comp - certainly not as that picture would suggest....................so remain confused!
-
You sure Clive? - I always thought they were down the bores and if you use the Busa rods they are above deck?

or sell the head and put the coin into a proper turbo to put the Busa pistons to good use
Yeah - earn some money and spend about 5 times as much and miles of smiles!
-
If you've the bits lying around why not but you'll still only get you back to standard CR without extra machining and the Busa piston crowns don't match a GSXR chamber once you've decked the block so more potential machining which lowers the CR again. And decking the block that much alters cam timing so adjustments there - lot of pissing around for not a lot of gain IMO. Sell the pistons and head and put the coin into proper high comp JE pistons that work out of the box!

Can't use the pistons AND rods in a GSXR 1100 - they are too tall unless you want to machine the crowns but by the time you put enough dish in there, there wouldn't be much crown left for turbo use! Just use the pistons on 1100 rods - they aren't ideal as the squish is to big but they give a turbo friendly compression that can be played with using base and head gasket thicknesses! They'll take a bit of abuse, hold up to 300hp if set up correct but the ring land is a bit thin so detonation will kill them double quick. Oh other thing - they need to be early Busa pistons - later mk2 had 18mm pins........1100 has 20mm!
Regarding compression it depends on how much boost you use! Low boost 'can' work with stock 10.5:1 CR but most can't stay low boost so some lowering is enevitable - I have approx 9:1 in a 1460cc motor that will pull over 2 bar boost but uses lots of tricky stuff to do it!

Its sad - the 3 axis bits look soooo smooth and shiney - makes everything else look bad! Its not bad, bad, just looks rough if you know what I mean?
My CNC mill is so small i'd have to turn that part around and do it in two halves - I have tool envy!
Different types of Harris frames pics wanted

It does but the tubing arrangement around the headstock seems wrong, some of the tubes seem a bit 'wimpy' and weren't tube swingers standard at the time? Rounded box section is a bit out of the ordinary!
Reference the picture for comparison
