Home made shroud

[LumpyVR4]

Since I replaced my dead stock fan with a garden variety thermofan, traffic has been an issue. In an effort to remedy this I whipped up a shroud today to see if running without one was my problem.




Update: Works a treat. I know it being winter helps, but now with the car sitting idling the fan cycles on and off like it should. I knew it would help, but I'm surprised it made that much of a difference.

Nicely done, looks like clean work.

What coolant temp is ecmlink set to turn on the thermofan? Are you saying without the shroud your new fan was not able to drop it below the coolant temp threshold to switch it back off in traffic (ie, fan always running)?

I should take ECMlink out of my sig. I tried to install it. Got initial setup done no problem, but once the car was warm I had knock issues off the line and massive over fueling at WOT. I posted logs on DSMtuners and the ECMlink forum and no one was interested in helping me so I gave up and went back to my Meek burned prom and 055 MAF. I'll have to use it with my upcoming (once I finish buying parts) stroker build with Evo head and Speed Density though.

In answer to your question (using the factory fan triggers), yes without the shroud the fan was always running. Now it only runs for maybe a minute at a time.

Nice job on this and effective too, by the sounds.
