LOL WUT?? A ported 102 hell even a stock 102 is good for at least 15 from an ls6 intake on a cam only to light h/c car.
The car probably doesnt make 465 but i will say it does probably make around 430. Those are decent heads and the 224r is tried and true. A biger cam would compliment the heads nicely. He's def making more than 400 though or at least should be. I still think the car should be trapping at least 4-5 mph faster

He has a 90 mm throttle body. If he had a 102 big mouth or NW, then I could maybe agree with 15 rwhp.
On HIS SETUP the LS6 intake works well with the rest of his mods eg. 90 mm tb, cai size, 5.3 heads and 224 cam hence his 119 mph trap. I know exactly how 224 cams perform; I had one many years ago.
An LSX 102 mm ported intake is not a magic "make hp on every setup regardless of cubes and supporting mods" piece.
No big deal. I can agree to disagree.
EDIT: and I agree with Fastfatboy again.
On a light FRC C5 this car is making 400-415 rwhp max with a 119 mph trap speed in decent DA.

Once upon a time I was on that dyno. At the time the car had a Comp XE 230/224 cam, stock heads, and 2.25" tails and some other exhaust restrictions compared to my sig. It was trapping 88-89mph 1/8th mile and 111mph 1/4. Car weighed at least 3760lbs raceweight then and like speedtigger has the aero of a brick.
Either the dyno calibration is off or your car isn't using it's power correctly at the track (shift points, your shifting ability, making different afr or timing under load, etc). I do think the dyno numbers look high either way. I would peg that for a 430-440rwhp combo.

Just as a FYI I had a similar combo with a 230/236 xfi lobe cam and a fast 90 and made 457rwhp SAE.
Here is the kicker, my car trapped 101 in the 1/8th (also went a full second faster in the 1/8th) before the header, valve-train and MAF replacement so it really went 101mph is worse DA with 440rwhp setup. A lot has to do with the driving which your launch ate up a lot of your ET and MPH on the front half. 26mph on the back half is about average for a C5 but I'd expect 28+ with a clean run. Unfortunately my old C5 broke all 3 trips I made to the 1/4 mile track.

I agree that my car wasn't making close to 460 on the night I made the passes. I think something is up with my car costing me power. But for reference a buddy of my that had his car tuned right after mine did by the same guy on the same dyno made 384 with bolt ons and a 231/238 cam in a m6 c5.

Yup. I disagree with you.
He has a 90 mm throttle body. If he had a 102 big mouth or NW, then I could maybe agree with 15 rwhp.
On HIS SETUP the LS6 intake works well with the rest of his mods eg. 90 mm tb, cai size, 5.3 heads and 224 cam hence his 119 mph trap. I know exactly how 224 cams perform; I had one many years ago.
An LSX 102 mm ported intake is not a magic "make hp on every setup regardless of cubes and supporting mods" piece.
No big deal. I can agree to disagree.
SameHey man I know it's a really old thread but I was wondering if you still had the Baer eradispeed rotors?

I do agree the ops car is trapping like a 400whp car. Should it be making more than that? Yes, realistically is should touch 420-430 and be trapping mid 120s

Ok here is a question. Can aftermarket valve springs wear out do to age alone or is milage the only factor? I've had the same springs for five years but haven't put an aweful lot of miles on them.

if you have the m12 with 3.42 then its gonna be pretty severe. you need 4.10 to put you in the same mph(around 123-127) at the end of 4th at 6800 as the m6 with 3.42 in 3rd at 7000(both with 26.7 inch tire)... I have 3.73 with the m12 and every time i race a c6 zo6(stock) the only time they gain any ground on the 1 1/2 cars i put on them from 40-140 is directly after my 3-4 shift

a ported 92 only got me 7rwhp going from a non touched ls6 intake... not everyone sees those magical gains

The old setup was a stock ls1 with rod bolts,ls6 intake,stock tb,ms3 cam and springs,stock 853 heads, 1 3/4'' longtubes,x pipe and catback. Made 408rwhp. Never made a clean pass but I think it went like 116-117. Seems like I remember it going 119.05 once also.Then the lifter twisted on the cam so I built the new motor. Just keep at it man. Youll get it whittled down in no time.

For compairison..Heres the new setup in my 99 frc...347,tfs215's,fast90,tick cam that kinda stuff made 468/415 with 500 miles on it. Two weekends ago we went three hours south since all the tracks was closed around here. My car was cutting out on each powershift. We believe theres something in the tune that needs some attention.Torque managment?And the track wasnt the best either.First time to the track with the new setup. And second time ever to the track with this car.It went 100.18 in the 1/8 and 11.07 128.8 on the big end.It still has alot more in it too.
The old setup was a stock ls1 with rod bolts,ls6 intake,stock tb,ms3 cam and springs,stock 853 heads, 1 3/4'' longtubes,x pipe and catback. Made 408rwhp.

also try to do just a quick smooth shift and see if it changes anything. A buddy was having the same problem. He would always slam the gears and the car would cut/miss. It didn't do it with me because I'm a little smoother driver than he is. We traced it to the balancer.

Did you tune it again? Or just bolt it on and hope for the best? Mine took tuning....which I think is normal for change like that.
A tip for you on your car cutting out on the powershift. It's probably your balancer....check it.

You should be trapping mid 120's or better with 464whp in good air. But remember alot has to do with driver experience and how/where you are shifting. Ideally you want to shift several hundred rpms above peak hp. You have to rev these motors to get them to really perform. But I understand that sometimes you can't for safety of the motor. It's not all about peak hp but power under the curve and your ability to apply that power to the track on a given day. So maybe your dyno numbers are a little high but you still need seat time to get it to perform. I'd make sure everything is mechanically sound and get back to the track. 10-20 hp here or there isn't going to make or break you. Make sure you have a good drag radial and pm me if you need launch tips or just ask.

I have a zr1 3rd gear in my t56, which is super long, and only lost a small amount of et over an m6. (with 4.10's)
