Added ported FAST 90 & NW 90 mm to the AFR's and 224/228 .563, I ran the car at the track but the east coast has alot of humidity and the numbers are equal to my best.(Oct air)

After 90mm:

Thanks to Mike at Rapid Motorsports

Pretty good gain. Nice smooth torque curve. You should be happy with your setup. Check out what I did with a FAST 78mm intake and Ported T/B.
Its all in the sig. Bad M/F'r !!!

Congrats on your #'s. Have your tuner lean you back a bit. See if you can make a little more power by setting that 12.8 to 1 to 12.9 or 13 to 1
Should see a few more hp/tq at the wheels.

I know I left LG Motorsports running a little rich, 12.6 to 1 while strapped to the dyno but ran outta time. I had to get back to Michigan. I was at 460/420 rwhp/rwtq Retuned it to 12.8 to 1 while strapped to the dyno and saw my #'s go up to what they are now 473 rwhp 431 rwtq. Might be worth looking into. You do lean out more when you are street driving too. I am considering trying 12.9 or 13 to 1 while on the dyno and see if it makes my car better, worse, or no change. GOOD LUCK !!!!

Nice Gain! I saw a similiar gain with my old 346 setup (AFR 205, 11.0:1, 224/228 .581/.588). I picked up 20 rwhp (417 before, 437 after) by replacing my ported TB / LS6 intake with the Fast 90/NW 90.

Stock TB(polished inside) on LS6 intake. Now just waiting for the fall(air) to trap a 120mph and get booted.(no cage)

What is the going rate for the 90/90 combo? 21rwhp and 15 rwtq is a pretty good gain.

excellent gains... I also gained 20 hp from the 90/90 swap

All ya need is the right converter and 10 sec passes are yours.

RGR Pete

and gears, I hear it all the time. Maybe, but this is a daily driver and I'm trying to keep it mild mannered. Skinnies for the track are next.

I'm glad to see a 90/90 only before and after dyno. All of the naysayer's have something to prove them wrong now!

BTW, to whoever asked how much a 90/90 setup costs I'm not 100% on the new price but I see them in the for sale section on here together for anywhere from 1000-1300 bucks.

Of last 2 months only 1.6's, It's usually 50/50 on 1.5's/1.6's.
E-mail BYUNSPEED for a price.
