Well I do like back rubs

I'll see if I can find my fci modded dyno graphs.....

But.... in short.... modding a intake is exact build specific. What works for one could very well sux on some one else's build.

heating and strategically stretching that thermoplastic is worth a bit of almost free power...

sredrum and i had done it on his machine when he was up at my place for a dyno weekend .... and i think we got about 1.5HP for the work.... that's probably in the range that terse got too....

This was a regular fci vs. after I modded it for this 522cc 100mm bore 13.1 CP, and HR+3 as boxed (yes it vibrated and cracked a lower motor mount)

i've tested both versions of the fci from short as possible to full length and i would agree with terse, it's build specific. motors are like women... very fussy!

Sup big man Dozer!

I basically get as far with a motor as I can with tuning and parts.... then look at the power curves, rev speed, and determine if the motor needs more cfm or velocity with regards to intake tuning, or a larger pipe for out going flow, a larger carb, etc.....

Obviously in the above build of mine at that time in it's tune it needed some intake modifications lolI

P.S. then after I find that missing link, I go back to looking at the power curves and decide what the motor wants/ needs..... and the process starts over lol

Well as long as you guys don't give out my info, I don't need 100 people at my door with lotion in hand and a warm towel by the ready
