Something Failed, let’s find it! Transmission Analysis.

Well then fit titanium sliders - I would suggest to the pants and not your arse - but to each their own.

Wow, on a recent trip south of the border @RKTNMYPKT heard that there was a special ointment that protects from all corrosion and abrasion BUT must be rubbed in by hand.
When he asked where, the shop owner said "Sorry Senhor, me no speaka good English - you know "Bare-asso", musta be sem in your country, no?

Jim didn't hesitate , slapped down 10 Pesos grapped the can and bolted. Ever since Jim has had no shortage of hairy bikers declaring their affections in many threads and offering to rub it in for him any time his wife is away.
Must be an 'merican thing ah suppose. North, South, Central - its all lost in translation to me

Well trans is in the mail on the way back, throttle bodies are in the mail on the way out

I picked up a dremel, put on a sanding wheel, spun it up then realized “This not the right way”, so my TBs got packed up and are going out for a full taper bore to remove the internal lip, permanently remove the secondary haft, and increase total diameter since I am at the point where they’re now the next bottleneck.

I was taught (by several different mentors) that the more turbulent the air was entering the block the better it mixed with the injected fuel and the better the combustion. Porting and polishing heads and TB's always seemed to be the opposite in terms of the effect they would have on air flow - presumably they make for a smoother flow.

Wet flow vs dry flow.

Wet flow, well, go back about 30 pages for some discussion.

Dry flow - the smoother the walls the better.

Turbulent in chamber = good!
Turbulent in runner = bad... up to a point, you want some.

These mods won’t change that in the slightest, but should (will?), increase both velocity and peak volume at peak HP.

But this isn’t about the finish, it’s about the lip. You can feel a not insignificant lip as a result of triumphs machining process where they go from a taper to a cylindrical bore down the TB about 1CM above the blades.

The math I did a few months ago resulted in a 56mm TB being a little bit undersized for my motor. Our TBs are 52mm at their outlet to the coupler, do definitely undersized for Steel and I, but oversized for stock cam motors. This is why Bob removes the secondaries, because the 265 kit is pushing the limits of the stock TBs.

I know at least one reader is cringing after a discussion we had, but, I’m going to be hard headed and stick to my intuition on this. I appreciate your advice and knowledge, I want to see for myself.

If I lose power, that’s fine, the forced induction guys will most definitely gain from doing what I’m doing, and I’m sure there’s a SC bike owner or two out there that wants free bolt on power in an even trade if this doesn’t work on an NA bike.

Thing is, I’m pretty confident I’ll see nothing but gains from 2000-8000 RPM because I’m not just boring them out, but taper boring, smoothing, and removing the secondary shaft. I’ll predict now, most of the gain will be 3500-5500.

People doubted my velocity stacks.... they work, dyno proven, they added torque below peak torque and cost me no torque on top.

You will gain power with boring them out.

 

[sleeves]

Hard on tyres it must rip them apart, what mileage are you getting 4-6000?

Bit old post now re road surfaces here, but this is a more accurate image of what we come across, never mind the tyres, its our suspension and spines thats failing

...well hurry up and get it finished...i NEED to see the reults!!

One thing about Rob -he takes his time, I sat at my comp for two weeks one time waiting for his exhaust to come back from the ceramic coaters I will never do that again as I now limit myself to one week

Yeah I’m in no rush for most items these days or I get stuck waiting on others so point in being in a rush.
