Drop In Filter Dyno Results - FT-86 SpeedFactory

Also, IMHO a simple under $50 part is being extremely overanalyzed and nit-picked. Take the results for what they are. A modest HP gain on a low price part. I don't think anyone else should need any more information on drop in filters.

If it doesn't matter, why quantify it? If fourth gear showed 5hp, fifth may only show 3. And 2 of that could have been from a cold baseline.

It goes both ways. I can also argue that in 5th gear it could have shown 7-8 HP.

I think the dead horse does not need to be beaten anymore. This thread is not about Dyno techniques so lets stop the thread hijack. Make a new thread to discuss that. I just thank FT-86 SpeedFactory and move on. They took the time to do this so kudos to them.

You have your opinion on Dyno thecniques, I respect it. Now let's keep the discussion on topic.

Thanks much for the info and effort. This is something I wouldn't ever expect to see on any forum unless someone was trying to sell a specific product. Great work!!

I personally think that having the dyno in the barn is awesome!

I wish i could test my Cosworth filter i can definitely feel it on the "butt dyno"

Thanks ft86 speed factory. I'm looking forward to seeing the results for all filters and will return this favor by ordering from you when the time comes. :happy0180:

The HKS has replaceable filters, so my questions are:

1 can you clean the filters or just replace filters?
2 how often^?
3 do you sell replacements? How much?

Thanks!

The HKS filter reminds me of a few other panel filters used, such as ITG. The foam style have been plagued with problems and longevity issues. HKS recomends replacing the filter every 10k miles, which kind of defeates the purpose of using a panel filter. I also came across this post a while back:

What do you think the chances are of this happening on the newer HKS filters?
The price makes the HKS filter appealing alongside the numbers, but for 5$ more you can get the K&N filter, which wont disintegrate and doesnt need to be changed every 10k miles.

Just posting this as an FYI, don't want anyone to ruin their cars.

It may be... but we REALLY REALLY appreciate the time and energy you have spent here. I can get the filters cheaper in SA and yet I will probably order them from you JUST because you have a nice website and took so much effort to get us this useful data.

There will always be people on the forums bitching whenever you post anything.. but then again how many of them have dynoes in a barn

All in all, you have done a great service to the budding 86 community and as an old time modder I salute you sir

I would just get the K&N.

It would end up going down like this. Anyone around a dyno a fair amount can agree I would think, but again maybe they are Flash Gordon and can rock it out faster.

1. Arrive
2. BS with the guys for 20 mins, look car over, eat donuts, drink coffee.
3. Strap car down. 20 mins easy. Have to line things up, double check straps, and etc.
4. Boot PC, attach spark read out on a HOT car.
5. 3 Base runs ( 20 mins 5 mins cool down in-between )
6. Cool down, filter change and BS time ( 15 mins )
7. 3 Filter HKS Runs ( 20 mins 5 mins cool down in-between )
8. Cool down, filter change and BS time ( 15 mins )
9. 3 Filter aFe Dry Runs ( 20 mins 5 mins cool down in-between )
10. Cool down, filter change and BS time ( 15 mins )
11. 3 Filter aFe Oiled Runs ( 20 mins 5 mins cool down in-between )
12. Cool down, filter change and BS time ( 15 mins )
13. 3 Filter K&N Runs ( 20 mins 5 mins cool down in-between )
14. Cool down, filter change and BS time ( 15 mins )
15. 3 Filter APEXi Runs ( 20 mins 5 mins cool down in-between )
16. Cool down, filter change and BS time ( 15 mins )
17. Unstrap Car ( 30 mins )
18. Edit Photos ( 60 mins )
19. Dyno Plot work, uploading, and etc (30 mins)
20. Creating thread, preview 20 times before submitting ( 60 mins )

Total - 430 minutes / 60 mins = 7 Hours of work for the thread.



(This thread took an arrival time of 9am and a departure time of 11am at the dyno, plus a solid hour of photo / thread time. 3 Hours in total. )

Again this is a sub $50 item. Maybe a little too much research for such a simple item?

Full intakes, you bet there will be much more strict runs and comparisons.

Off to bed. I'll hit this up first thing in the morning.

sales of your product are not worth much to you
