I was going to do the
FAST 102mm with FAST 92mm FAST fuel rails with 42lb injectors.
Im also getting a 98mm air lid.

The only reason i dont want to get the NW 102mm TB cause then ill have to get a 104mm MAF, and a lid to match. Im already pushing my budget for the build

 

That should work fine.

Also Chrs1313 has said the FTP 98 and 104 don't really show improvements over say an SLP lid (like nothing), because they may have 4" openings but neck down to 3" to make it over the radiator before opening up to 4".

Also, Vengeance just posted a FAST 92/92 combo on a 402 using an SLP lid and stock 75mm MAF and it made 524rwhp. Would it pick up more with an 85 and bigger lid? Only if it was pulling vacuum...

So, I'm going with an SLP lid, stock MAF, 102/92 combo and Fuel Rail kit. I think that would be easiest to tune and still provide probably 15-20rwhp increase at peak and much larger under the curve gains when paired with a decent set of heads. Also, the stock bellow works with the 92. I have no clue if it would fit the 102.

 

im not understanding. It looks like its all the same size.

Yeah, I don't know. It looks like it necks down a little bit where the radiator support would be. I think the 98 will be fine if you don't already have a lid. If you're going to run SD, that's the lid I'd go with hands down.

 

SD? im also getting the SSRA to go with it. im looking to make 450-470hp ish in a DD 6-speed camaro.

 

Speed Density with no MAF.

 

Oh. How much/how hard is it to do that?
