Fast 90/90 with a mild H/C set-up?
Fast 90/90 with a mild H/C set-up? From what I have seen most everyone running a Fast 90/90 combo with their H/C set-up have a decent sized cam. By "decent" I mean 224 duration or larger. Some of the gains seem fairly good. But what if the cam was smaller than a 224? 
I am currrently running a 220 duration cam with a set of AFR 205s. Will a Fast 90/90 help me out any or should I just stick with the LS6 intake? Anyone have a combo similiar to this? If so, was it worth it?
Thanks.

I am in a similar situation and have spoken to Tony on this, his estimate for his ported 90/90setup is around 25hp. That's around $75/hp, which isn't bad compared to other installations that either net less hp or are harder to install like heads. My cam is a VHP 056 with 216/224 on a 115 LSA.
I recently helped a customer with a bonestock LS1 shortblock that races in the SI classes (stock internals). I ported a FAST 90 for him with a caveat being I couldn't promise him the same returns most people get from my set-up (20-25 is typical). He didnt care and would have been happy to pick up five as it seems this class is fairly competitive. Long story short is he picked up 12 RWHP peak to peak but over 20 HP past peak where the stock intake couldn't keep up. He lost nothing down low....saw gains everywhere.
Dave....if your out there maybe you can chime in. Alot of people claim a FAST is a waste of money on a stock displacement engine (even with better flowing aftermarket heads) and I couldnt disagree more. Even an extremely mild combo can benefit from the extra airflow.

Question, do you know who makes a lid that can support a 4" inlet? Now that my MAF is gone I want to match the intake up to my Nick Williams 90.
I tuned a guy's 2002 SS last week that was running stock heads and shortblock, but with a 242/248 T-Rex and a FAST 90/90. It made 455rwhp/402 rwtq. I was blown away by how much power it made with the correct tune. Awesome. The FAST 90/90 was worth 20+ rwhp in his cam-only application at 6500+rpm

Spark seems to have a small effect on these cars at WOT beyond a small delta. If you don't mind, shoot me a PM i'd love to ask you a question about the VE / RPM / TPS multiplier tables.

Was this over an LS1 or LS6 intake?
