Are you trying to compare Skips dyno numbers to his 1/4 mile MPH? Or the shop car dyno numbers?
My dyno reads fine, it isnt high nor is it low for the area. If you dont agree with the dyno vs mph then you need to look at the 1/8th mile mph, 1/4 mile mph and also the half mile speeds. Dont just look at the 1/4 and make judgement.

Well yeah, typically I look at 1/4 trap speed. 1/8 trap may not be as accurate for judging HP due to the front half variables...(lots more converter slip, traction, shifting etc)..
I do think a lot of the missing mph in your car and Skip's car was due to the trans shifting etc etc, especially on your shop car as it obviously had a trans shift problem at the track...(I know it was your first trip out with it and not dialed in). But going off of your 127 mph 1/8 trap to take some of the trans issues out of the equation, thats still barely 1000 rwhp if that.....Let alone 1300+rwhp..... Hell I went 122 mph (1/8) and 151 mph (1/4) with 850rwhp at 3610lbs in a C5Z, that was with 11.5% converter slip...
But yeah, Skip's car trapping 150 mph at 3700lbs is more like 850-900 rwhp, not 1100... Even if it had a stick, it wouldnt take 1100 to go 150.
Charlie's 1400 rwhp C6 barely ran with Frankie's 1200 rwhp on the street.
I'm not knocking your shop, your work or your tuning, I have always been impressed with David's car at the TI stuff..
I just think the dyno numbers are heavily inflated.
Same goes for LMR...their red C7Z makes 1200hp and traps 142mph? really? a 700 rwhp car will do that if it actually shifts right, therein lies the problem with the A8 cars, seems no one can make them shift 100% right.
Just my .000002...

If it were true that a dyno "needs to be calibrated big time", would stock horsepower level cars be effected on that same dyno? I have no skin in the fight and have no work done by AMP, but until I see other cars run the same times at the drag strip or trap speeds in the half mile events, I would say their dyno has been pretty accurate.
Absolutely correct....
However you rarely see stock HP car dyno charts come out of AMP....
And if you did, I am sure you would see some HUGE gains when the "after mods" numbers come in.

If you want to hate on a shop for the dyno numbers maybe you should hate on the guys who dont hold or break records, hate on the guys who are not paving the way for you guys that eventually want to modify their Z06/C7.

You are going off of opinion not experience with the same platform or math.
Frankie GAVE UP on that race with Charlie. Once Charlie put two cars on him in one gear (3rd) he turned around and went back to the track with his tail between his legs. We tried to race him several times since that night with zero luck. Thats not a race I would comment on in the future if I were you.
This is true.

Are you going to completely ignore the 1/2 mile speeds? I would if i were you too.

But I do agree with you on one thing, you guys are pioneering the C7 platform and coming to market with products many people will want, including myself. Hopefully you guys continue the R&D....especially on the A8 trans shifting.

Wait a minute.. You said the dyno needs calibrating, not the dyno setup per individual mod to "inflate" numbers. I first hand can tell you that their dyno on a stock car and with a small mod is dead nuts on, period. Your claims are bogus and have zero backing.
What did your car dyno with just your CAI?
What did your car dyno with just your CAI?
I will say my C5Z ran close to Skip's car(well a little quicker/faster actually) and it did dyno 250 rwhp less....at the same track Skip raced at...(Obviously different days and different DA)... And my car was within 90lbs of his so.....
I just call them as I seem em...
As for my C7Z with JUST a CAI.....I've learned my lesson on building/modding late model vettes, when I want to go fast again, I'll build something to do so.. I'll just be doing bolt ons/tuning etc on this one and you can bet your *** it will be verfied on a track, not a dyno.

Let's get this thread back on track..
So how about the highest HP Stock blower cars? Both head/cam/exhaust/ported blower cars and stock long block builds...
RWHP:
1/4 mile ET/MPH:
1/2 mile MPH:
1 mile MPH:
Let's share them...

That and lower drivetrain loss from lighter wheels/tires and smaller differential? Not sure about gear ratio or brake differences.

Different days on the dyno. Different octane level of fuel. Tolerance in the build of the engine. There's a ton of things that make differences. I would never worry bout the hp numbers a camaro puts out. If I wanted a bigger car with a backseat, I'd buy a GTR. I don't think any bolt on zl1 will outrun me and if it does, oh well.

Former Vendor
This was with
Haltech CAI
STOCK TB
STOCK UNported blower
STOCK cylinder heads
Our Stage III Camshaft (low 230s intake duration)
Long tubes/non catted X
Alky Control
E85
No lid spacers or aftermarket cooling mods other than meth/E85..
On a 150 shot the car went 151mph in the 1/4 and 177 in the half at over 5000ft elevation.
We have an A10 ZL1 on order and will be modding in similar form initially.

Well mine is going under the knife on 4/7 at Katech with the intention of maximizing HP with Stock Supercharger!
It currently is 580RWHP 597RWTQ with Halltech, Ported TB, Ported Heads and Akropovic Evolution exhaust!
Katech will install the following:
LPE 35GT 35 Cam
LPE Injectors
LPE Pump
GM Racing Lifters & Katech Valvetrain
Supercharger Pulley
Balancer Pulley
2"ARH Headers connected to Akropovic XPipe ( Weight Reduction)
Katech E85 Fuel System (Running 100% E85)
Katech Oil Cooler
Dewitt's Radiator
DSC Sport Suspension Controller
Tuned to Full E85 / 106 Racing Gas
Hoping for 800RWHP
Wanted to add TIKT system but too pricey and install time right now.
