Default Fast 92 1/4 results?

I see a lot of dyno graphs getting 15-25 depending on mods vs an ls6 manifold, but what really matters it the et and mph to me.

So what are we looking at, Post up your before/after 1/4 fast90 results if there are any here.

I didnt see must improvement from going to a ls6 intate and a bbk 80mm to my fast 90 ported but my motor was mostly stock. My new motor I have heads and a huge cam. I think it depends on your set up. I would not waist my money on the 92mm if I did not have the cam and heads to benefit from the extra air. just my 2 cents.

Best before refreshed tranny, TCI SSF 3800 stall and ported Fast 92: 11.78 @ 114.55. Best after refreshed tranny, Pro Edge 4000 stall and ported Fast 92: 11.57 @ 117.46. Different dates, but similar temps and humidity.

Even though I had a few extra changes, I believe the Fast 92 had the biggest impact on my mph.

Yeah i don't see the converter giving you more mph, but what was both 60's. If i can get 1-2 tenths and 2-3 mph i'll buy one.

My 60' for the 11.78 pass was 1.60 and the 60' for the 11.57 pass was 1.61. Though, the converter I have in my ride is larger, it's tighter for the bottle. The TCI was super loose.

I went from a LS6 intake to a ported Fast 92.

On a different note, I hope to gain a mph or so with the Fasttoys 90mm lid and SSRA this Spring. Brad (silverz28), I'll let you know if it helped just in case you decide to go this route, along with the Fast 92.

Typo, my bad. In reality though, the opening of the lid is actually larger than 85mm. It's more like 90-95mm.

I'll find out in three weeks if it helped.
