Why such low numbers?

Why such low numbers?
Please look at my sig and tell me where the restriction is. With all this work and money spent, I'm not even making 400 at the wheels. It's a new motor that has seen ZERO miles street usage. Motor was bored/honed with torque plates, so, breaking in at 3,000 miles will probably yield me maybe 10 RWHP if I'm lucky.
Any ideas? I'm hoping the engine is just REALLY tight and will produce better numbers. Dyno was with street tires and smallest Borla restrictor plate ... TQ converter unlocked. Next dyno will be with the new MT ET street radials and wide open Borla. Think I'll gain much?
Hopefully, on this particular setup I'll get a great ET/mph at the traps and numbers won't mean much.

im not sure what your expecting, playing the dyno game with your setup and you'll only be dispointed. you've got a hp sucking drivetrain, on top of the inherent greater efficiency loss compared to the t56.
what CR are you running? and as ^ stated, running through an unlocked convertor will kill your numbers as well.
take it to the track and then report back.

Converter is unlocked, and you are running through a 12 bolt. Also, I see you have 17" wheels. You're also giving up a little by not having a FAST 90mm set up. JFWIW - on Mike's dyno I only picked up about 5 RWHP by locking the converter. I have a Yank SY3500 in my car.
The wide open plate should free up a little, but the tires may hurt your dyno #'s. I have them, and they are heavier than my regular radials.
I wouldn't sweat the #'s unless you dyno race. I feel you'll be pleasantly surprised when it makes a clean pass down the track.
I have a similar set up going together in the next few months. Mike @ NLP will tune this one as well. My short block is on it's way, and next month my heads and FAST intake go back to AFR for some touch ups. I also went with a slightly bigger cam than you from AFR. I'm running through a 10 bolt still... so I expect to put up slightly better #'s. But, if I had the money... you can bet the farm I'd put a 12 bolt in my car too.

Oh yeah, almost forgot....I lost 12 SAE rwhp going from a stock 10 bolt with 3.73 gears to a Strange 12 bolt with 3.73 gears...There's some loss right there for ya!

my eyes hurt trying to read your sig.....
but you have a solid drivetrain eating up some power.
take it to the track and see how she runs...
fwiw, is this another "Mamo" combo?

A4's and dyno's go together like turds and hotdog buns. Use the dyno to tune you A/F with and then run the A4 at the track to see how well it performs. I LOVE to race dyno's.. so that's why I have a 6 speed

Thanks guys. The motor's in and the FLP level5 4L65E is in ... haven't installed the 12-bolt yet. It and the driveshaft should be here, hopefully, this week. I'll report back the dyno numbers soon. I'll also answer all the questions I can. It's going to the track in about 2 weeks and I'll report track details, as well. Thanks guys.

Thanks Dave ... appreciate it.
Yeah, it seems Mike's dyno is known to produce substantially lower #'s than most dyno's. With the coverter locked, I agree, it should give up about 20 RWHP. I think the SS3600 is about 95% efficient (which seems to be about right).
As for the waterbox and staging, I certainly appreciate any pointers if you're there. I plan to hit the waterbox and do a slight burnout until I feel the car start to pull down. Then, I was going to stall it up to about 2500 rpm and floor it. I believe this is how I'll approach my first launch ... glad to hear the track is hooking better.
... maybe they're prep'ing it better and throwing more VHT at it?

Yea, Mike's dyno is a little low. Had a buddy dyno 11rw less their, compared to Auto Tuners(when they had their dyno). Put the 12bolt in and bring it to the track!
P.S. I'm the kid you met today at the BP

It was cool meeting you today, man. I've seen you around town several times. Nice red SS you got there. I'll prob race on Sunday ... not sure yet. I think I'll pull a pretty good timeslip if I can get a good launch.
Since I put the MT ETStreet radials on today, I can feel a world of power difference in the feel of the car ... compared to how it felt before the engine work Mike's folks did for me.
Gotta' run. i'll be talkin' to you ... take care.

Yeah, but, I'm so committed financially, I won't be able to the nitrous setup I want until next year. I liked Dave's S/C setup so much, I have about decided to go that route, which will take me another year or two. A good DP nitrous setup like I want is about half the price of a S/C, so, I'm thinking I'll be patient and wait so i don't have to keep refilling the bottle ... only thing is, the heat in the summer is my concern with a S/C. Nice having the power ALL the time, though. Right now, I'm having a little more fun with my new setup for sure. Once I put the MT ET streets on, that's when the fun really started ... irregardless of the dyno numbers, I think I'll pull low 11's with good track conditions and some practice launches ... just my $.02 worth.

There's about 10 cars supposed to meet up at SCC at 9:15 on Sunday morning. You ought to meet up there with us if you plan on going early. I may leve later than that, but I'm not sure what time I'll head out there if I don't leave early. I'll PM you otnight or early tomorrow a.m..
