MaxPower Posted October 15, 2021 Share Posted October 15, 2021 Google say they’re air jets, thought the bigger number would have been on the secondary , castings look great. Will spend some time driveway tuning it on Sunday mornings pretending I know what I’m doing 1 Quote Link to comment Share on other sites More sharing options...
Sambo Posted October 16, 2021 Share Posted October 16, 2021 Aloha gentlemen, if one were to blow down a 1/4" fuel return line, how much resistance ought one expect to encounter? I've just dropped the gearbox out of my car to swap over the "semi blocked" fuel return line in the car, then I went to test the spare and found it completely blocked. I put some compressed air down the one in the car again and it seems to have improved, but I'm hesitant to put the box back in unless I'm sure it'll work. Edit: Follow up question, is it feasible to bend ali bundy tube by running it under the car, or does it really need to be bent up then installed?

tortron Posted October 16, 2021 Share Posted October 16, 2021 I have done it under the car, its flexible enough to get the tool on it in most situations. You can hook a fuel pump up to it and measure the flow per minute 1 Quote Link to comment Share on other sites More sharing options...
NickJ Posted October 18, 2021 Share Posted October 18, 2021 Is there any trick to welding 6000 series aluminium extrusions? Have a small side project that would be much easier if I started with an extrusion but being a noob at Al welding i have no idea about the finer points Quote Link to comment Share on other sites More sharing options...

Isn't unusual to have a larger one on the primary for fuel economy at cruise and having the secondary jetted richer for power under load. I'm keen to see how it works for you. I've got a couple Chinese dcoe 45s coming for a project. I've had issues of rubber components in Chinese carb kits not liking our fuel and swelling in the past. So wondering what these carbs will throw my way. Quote Link to comment Share on other sites More sharing options...
Jeffs_Emporium Posted October 22, 2021 Share Posted October 22, 2021 Since changing to a braided rear high pressure fuel pump I'm getting horrendous vibrations through out the car, the fuel pump sounds like a 747 and changes pitch a lot . So much so that I bought a new fuel pump. Is this common if it's touching the body? Quote Link to comment Share on other sites More sharing options...
datlow Posted October 22, 2021 Share Posted October 22, 2021 Not rubber mounted? Quote Link to comment Share on other sites More sharing options...
Jeffs_Emporium Posted October 22, 2021 Share Posted October 22, 2021 The fuel pump has rubber mounts to body. Braided line is touching body on the loop off it but not clipped to anything. Best to rubber clip mount it to body? Quote Link to comment Share on other sites More sharing options...

oldrx Posted October 26, 2021 Share Posted October 26, 2021 If I am wiring a 20 Ohm resistor in line between oil pressure sensor and dash, how many watts should the resistor be? Quote Link to comment Share on other sites More sharing options...

For an oil light? If you have a dead short for a lamp, 7.2w will flow at 12v. What is the resistance of the lamp? Quote Link to comment Share on other sites More sharing options...
oldrx Posted October 26, 2021 Share Posted October 26, 2021 Sorry confused myself (too many half finished jobs) resistor is actually for water temp sensor to factory dash gauge (original RX2 green ring sensor is NLA have to use later black ring type which will read wrong without resistor).

87creepin Posted October 28, 2021 Share Posted October 28, 2021 How important is exhaust and intake valve timing adjustment in boosted applications? Guessing its not as important as in n/a tuning...? Quote Link to comment Share on other sites More sharing options...
oldrx7 Posted October 28, 2021 Share Posted October 28, 2021 Adjustable suspension / struts question - had a search but couldn't find the thread / comment I thought I'd read a long time ago. I'm looking at (in the near future) to be buying some FC rx7 adjustable suspension. From searching around various websites, there's a lot to choose from; XYZ = $1700 Lines Racing = $1100 Hakon = $1600 Yellowspeed = $1600 D2 = $1700 BC Golds = $1800 Max Pro = $2300 Plus I'm sure there's so many other more well-known Japanese brands out there for sale also. My question is - any of the above brands known to be not great/shit/not cert-able? Do I just purchase roughly based on price? Avoid the cheap one and stick with the mid-range?

cletus Posted October 28, 2021 Share Posted October 28, 2021 If I was picking suspension from that list, BC 100% Probably the most common brand I see, and apart from setup/adjustment issues, I've only had 2 sets have problems that I can remember in 15 years 3 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted October 28, 2021 Share Posted October 28, 2021 I have had a set of second hand bc's in my hillclimb civic for ~40 events now. They have had a bit of a beating and are holding up well, only thing is with my weight reduction I have to run the rears on pretty much the softest setting, and I swapped to a softer rear spring. Would buy again for the price. Take that TOTP / no context. 2 Quote Link to comment Share on other sites More sharing options...
