I don't know just saying there seems to be a fudge factor more than just looking at square inches comparison according to the link I posted. Looking at the chart at square duct 100mm by 200mm is equivalent to 152mm diameter Comparing just area square duct 100x200 =20,000 square mm vs 152mm dia...

Plugging and chugging the equation for an oblong pipe of dimensions 3x5-1/8 I get an equivalent round diameter of ~4.1" de = 1.55 (π b^2 / 4 + a b - b^2)^0.625/(π b + 2 a - 2 b)^0.25 a= 5.125 b=3 Someone can check my math its been a while. This is a mathematical approximation. It does not...

Welcome to TTS.

I am not a fan of stacks. I am more of a function rather than looks. Why cut a whole in the bed? The only reason for a stack IMO is if you are pulling a trailer with something you want to minimize the soot stain. Or a tractor you don't want exhaust choking you as you hook up attachments...

Neat to see such big components in a smaller machine. Sounds cool! I wonder what the idle rpm is? That thing had a bunch of rings. Was almost like a diesel powered hydraulic ram. Different way of explaining torque curve on the rpm part. Really highlights how a big mechanical ip governs...

Welcome to TTS. Congrats on your new to you truck. They are nice to have.

Glad they don't seem to be messing with stuff. Might take a while to reveal their damage because it is a small bite at a time. How long have they been there and expected to last? Just thinking about it I wonder if.... What NVW posted about them eating maybe a poison plant supports this...

Yeah, radio DJ talked about it on my local radio. The video's of the swarms are impressive. Here we have skeeter meter's low = nice day for a walk, Full scale = Don't open your mouth. The video's look like you can't open your mouth. Birds will have eaten them so much they'll be sick of...

I like the screen idea and malathion. I don’t know but some bugs are drawn to light colors thinking they are flowers. So a bit hesitant about the white sheet unless you know grasshoppers don’t like the white background and they feel exposed. Don’t know if there is something like citronella...

Glad you found it. Doubt they have ever had anyone have the balance numbers from tested. Isn’t the clutch advertised as either a performance or at least OEM specs. Might could argue the LUK balance specs if Phoenix won’t supply theirs. At least have numbers to explain to PayPal why your...

I can see why this engine got such a bad wrap and so few shops were able to work on it successfully. It took me a couple of tries to catch on. To be fair Carcode confuses me. Not sure I cleared codes correctly once or twice. I do it from status window and again from enhanced but enhanced...

I have done the box end of wrench on the open end of a wrench for added length. Works good for just tad more umpf but has dug into a few wrenches. I like the flat bar cheater. I try to always have tape and several small superglue packages available for when you can't hold something in place...

Working on IP timing the bolts are tight to get to. I cut the open end off a ratcheting wrench. I ground some off the sides too. I could thin it up some more. As is I still only could get a small ratchet turn maybe 2 teeth on the wrench due to gear lash and the number of teeth in the...

Welcome to TTS. Looks like a quality build in progress. Oh, and we are pretty good at encouraging spending money. I would want to coat piston tops with a thermal barrier and underneath with thermal dispersant. Don't think they can balance with Fluidampr. Seen several posts on the...

You can google heath's balanced flow kit to see some of the early attempts at adding flow to the rear of the head. I think adding hoses at the rear blocked off ports somehow isn't increasing swirl over the head's hot spot(s). It might increase flow somehow at the rear but it doesn't mix and...

It’s been tried. # 8 gets some temp increase from the exhaust crossover design. The spin on water pump fixes the problem. Not only is it better balanced it’s higher flow. More flow mixes the water in head better and flushes away hot spots.

Thank you. I agree. I think my pump was too retarded to begin with and I super retarded it like someone I know. I read ignore IPT and IPTD and could go by TDCO value: read, adjust, learn and repeat as needed to obtain proper IP time position. If this is correct: TDCO =-0.5 =~ base time of...

My truck has a surging at launch when its cold but after it warms up past 170F coolant temp it launches smoother. Since I had replaced the timing gears I thought why not investigate timing and TDCO since it might be 50 starts since then and relearned to start causing this surging. I am using...
