I have a heads cam intake car and am using a ported/ polished 80mm bbk tb a ported stock maf and a slp lid as well as a set of hooker headers. how much am I leaving on the table by not switching to ported/polished 85mm tb ported/polished 85mm maf and a larger lid and larger headers?

am I leaving 10-15 hp 15-20 hp or 25+hp on the table?

what intake is on the car and what headers do you have now?

Definitely not enough that its worth the money to do it all. Going 80 to 85 just isn't much at all.

Maybe 10-15 hp.

Get a set of L92 ported heads for $1500 and make 40-50 more.

If anything go with a ported fast 92.

Agreed with BlkBird, Buy a fast 92/92.

at the moment is has a ported wiend ls6 intake ported 5.3 heads similar to texas speeds version and 1 3/4 hooker headers. One thing that does not interest me at all is the fast I have been rading to many bad reviews to pay 700+ for a piece of plastic wich may or may not have as high of quality as it should.

i'd say 10hp or so by not going bigger on the lid/maf

but you'd need a new tune after the maf.

you could gain some with the FAST...but again not a ton.

going from stock ls6 intake, and ported stock TB....to a home ported FAST 90/90....i gained 18rwhp and 12ftlbs of torque peak, and 5-12 hp and torque from 3000rpm and up.

it was worth it for me.

the FAST is a quality piece....

A lot of people including myself run the Fast with excellent results.
