Bullshit Alert.
He has much less HP.
I don't believe any chassis dyno figures anymore. Like Phil.

1/4 mile or Numerous Engine water brake dyno pulls prove all.

Id keep an open mind , the reason is that lack of the correctly set up suspension and tires, can result in a great deal of wasted power and lower trap speed, when I built my 1968 corvette with the 4 link dana 60 rear and a 13.7:1 crower injected 496 BBC my times were in the 10.26 & 137 mph range in a 3200 lb car with a 220 lb driver, by todays standards that car should easily run 9.7 at 139 mph but keep in mind I had the wrong rear gears and tires (slicks) that sucked by todays standards and I was in my early 20s back in 1970-78 when I was seriously racing, and had no where near the experience to properly set up a four link suspension properly when I was in my mid 20s
so if a guy claims to have more power than his et and mph indicate Im far less reluctant, to give him the benefit of the doubt, than a guy running times faster than he should be as I'm sure your aware power, at the fly wheel, is only one of several factors, traction,gearing, weight and aerodynamics come into play

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

Maybe Grumpy.
I have watched at least 10,000 cars go down the 1320.
15-Seconds to 5 second runs.
Been racing myself many times on track & street.
I especially like the 11-low 8 second race cars because they are the working guys that hired me in the past to turn wrenches for them.

I still call his 975 hp claim bullshit.
Be in the low 9's 1/4 if true.

I was curious this morning Grumpy so I priced out a TCI 4L80 E
3,000-3500 STALL SPEED TORQUE CONVERTER WITH ANTI BALOON PLATES.
10.0" INCH UNIT.
# 242942 TCI STREET FIGHTER
$1660.00 FROM SUMMIT RACING.

I would call it a 10-second car torque converter only.
Not for a 8-second drag car.

My Turbo 400 Torque converter I want with same specs is much less $$$.
$512.00 from TCI. TCI SUPER STREET FIGHTER.
For my 1963 Pontiac Grand Prix.
I am staying Turbo 400 Grumpy.
Better Value for me.

The Torque converters made for TH400 & 1400-2500 HP Ratings still cost around $1200-1400 bucks.
