FAST 90/90 results on Z06 Hi folks,
I finally got my 2004 Z06 on the dyno here is my old post: //www.ls1tech.com/forums/showthread.php?t=292558&highlight=mcneil141
I have added a FAST 90 intake and a LS2 TB (both ported by me), and a two tip Borla Stinger exhaust. My old numbers 430rwhp and 404rwtq corrected, yesterday I made 455rwhp and 413rwtq corrected, on the same dyno, at 12.9 flat across the board.
I guess this is one more piece of evidence that the 90/90 makes more power.
BTW, I am using the stock injectors and hit 100% duty cycle
. Should I buy 36 or 42's? I think I'm done with modifying the engine 
.

I have the Fast 90 on my car and it didnt gain me anything. I didnt port it though. I made 475 with the stock injectors on my stroker and when I added thew Fast stuff we went with 36#.

SWEET!!!
How hard was the LS2 TB to tune for idle and part throttle driving???
I am using SVO 30#s and have had no problems. I have hit a max of 74%, duty cycle at 450rwhp(sae). You will be fine with them!
...congrats

Hi,
The LS2 started right up with no problems. I have the smallest bit of surge at 1800, but I will solve it eventually (some of that may be left from incomplete tuning from the cam). I read that the LS2 gives up a few ponies over the NW unit, but the drivability is great. Most would never know I changed something.
When you get the FAST, you will see what needs work ..sharp edges, flash lines, and some protrusions. I also completely port matched the lower half, placing the unit on the heads, then removing, grinding and sanding to match. I finished up by wet sanding everything I could reach. I spent quite a bit of time on it, but that's how I relax.
BTW, my FAST was NOT warped and I have no complaints. Be sure to order new manifold gaskets.
The FAST is well worth the money. I bet you make at least 20rwhp. My first pull with no tuning was 447rwhp which is 17rwhp over where I started (remember that I added Borlas, too).
Thanks for the info, I will order the SVO's tomorrow.
If you have any questions, let me know.

Congrats. Those are some solid gains with the FAST 90/90.

Very nice. If your sure that the modifying is over the SVO 30# injectors should be fine however, if there is any doubt in your mind go with the SVO 42# injectors that way you will have one less thing to think about down the road.

Great gains you made.I picked up a total of 10 rwhp with my FAST90 and NW90 TB over my LS6 intake with ported TB.I wonder how much the exhaust change was worth?
I run SVO 30 pound injectors.

Thanks for the compliments, folks.
(From what I hear) the exhaust change is mostly for sound, maybe a few rwhp. The stock Ti system flows pretty well. Sounds good though....
I studied my duty cycle from my dyno pulls.. I am *just* under 100% duty. I think the SVO 30's will be perfect.
Keep in mind that my gains were over an LS6 intake and stock TB.

Nice gains. Figure 5rwhp for the exhaust if lucky, so a soild 12 is not bad. I personally believe that the more these engines are modified (heads/cam/headers/exhaust/TB/intake) the more rwhp the FAST gets.
Thanks for the info and congrats on the new numbers!

if you're at 100% now, then svo30s will bring you down to maybe 85-90. get the svo42s and run with a healthy margin, the differnce is like 50bux anyway.
other than that, NICE numbers!

I also just installed the 90/90nw on my 02ss havent tuned or been to the dyno.but my buddys 02CETA makes 415rwhp we raced and were side by side all through the gears his is a manual mines a automatic Any guess how much power im making,ls6 cam,hk long tubes,lid,tci 3500
