I now have over 25 Shroud designs on my website, with new customer reviews weekly.

I will be coming out with a shroud for the Behemoth 14" Brushless SPAL, but as you know it's expensive. In this hobby, almost everything is "You get what you pay for". Finding that balance is the fun part.

As for the previously mentioned comment about the "Skid Plate" I designed for 64 to 72 GM A-Body's, it protects the Oil Pan, not the headers. It has saved my 69 GTO twice since installing it. Just did a video about the skid plate damage here; https://youtu.be/Q0DA63Rofos?si=c-vv8jUBctsGg_Ik

Any other questions, let me know on YouTube or through my website https://www.fastmontysgarage.com/

See ya!

You'll probably get a buyer for me once you do. Will you be making that 14" Brushless SPAL shroud for 70-81 Firebirds?

I'm running Mike's shroud on my 66 GTO and over here in the Australian climate we have some pretty hot summers. I ended up running the proform brushless fans with the proform PWM controller because the sniper won't output PWM. I just did a 400 mile round trip 2 weekends ago and the car was flawless! The car ran cool, looked cool. Awesome product!

Seems to have gone up in price a bit Check out this page from Summit Racing https://www.summitracing.com/parts/d...iaaegj-npd_bwe

Yeah I went with the slightly larger shroud on my bird, the 18927, and run the 16837 on the GTO. Same fans in all 3 of those. I have the 16837 in the 442 as well.

Like I mentioned, the 535 is borderline, and am thinking if stepping up to the FMG 14" shroud and Proform fans.

Mike - Some reason I thought the bat wings would help cover the headers some, guess I should have looked harder! So the bat wings are more for stability/strength? Glad to see you on here!

Protecting the headers would have been a bonus, since right now, for me, headers are disposable items! Heheh!

I feel the same! My headers are border line trash as it is... way more important to protect the oil pans, as we'd have to fully remove the engine to fix that debacle, let alone rebuild it.

See ya!

It's plausible, here's a rendering and picture of my first try at the A Body Shroud, for a FrostBite FB304 radiator, it's beefy. This customer was ok with welding the corners, as my next design needs to avoid welding. The F Bird core is 1" narrower. So, keep that in mind for clearance on the sides of the radiator would grow 1/2" on either side.

If I decide to switch from a factory style clutch fan & shroud in my 535ci 70 Formula to electric fans, this is what I’d go with.

At roughly $1350 for a set of Doug's these days, every scrape is a total cringe! Heheh!

I'm dropping back to the 1 7/8 ones, they fit better and tuck up better too.

So, just to comment, when you go to dual fans that are like 28a each to a 60a spike, you need a better alt, and you can only do like 140 MAYBE 160a alts on V belts. So it's serp and beefy alts. Soft starts are really the only way to go, and even so, you could probably draw 80a at idle. Or more.

Take that into account when you start doing to e-fans. This is the one thing where people fail and throw in the towel on with e-fans.

Monty - great YT channel, watch it all the time.

If you have time, any thoughts on using a late model (say 2500 or 3500 Chevy HD truck) fan blade assembly on a Hayden clutch fan ?

I would guess they'd pull plenty of air.

I saw you measured airflow when you tested the electric fans.

Slicker "test" would be the matching ECM controlled clutch fan.

But, more curious on airflow...........

Keep up the good work - we appreciate it.

Would like to see the cfm air flow of a stock shroud & a 19" 7 blade severe duty clutch fan.

This, this, and this. It would finally lay to rest a lot of discourse between e-fans and mechanical fans.

My guess is that a mechanical when setup properly will outflow all of the electric fans.
