HERE WE ARE! (my bad lol) Dyno-Comp - Blog

BTW, the **** was NOT on, they claim it was but it wasn't. Still debating if I want it engaged or not...decisions, decisions.

Very good for paxton!

Now get to the track and put down some real numbers!!!!

 

[SandViper]

Im not much into rims. I like stock over anything else, The wheels on that car look great on it. Does anyone know what size they are?

 

[Zentenk]

Hit up the Nurburgring!!!!

 

[plumcrazy]

stock motor i assume ? hope its got a fuel system on it. sounds great and i like the wheels

 

[Red Snake]

Their estimated flywheel numbers are WAYYYY off.

• HP is now at 703 (at the wheels) which equates out to about 892 HP at the flywheel.
• TQ is now at 762 (at the wheels) which is approx 967 TQ at the flywheel.

It would be more like 787 HP and 853 TQ (or about 12% more, not 27%). Still very nice rear wheel numbers.

Answers to your questions...

- 20" all the way around, Iforged "Classics"
- Not a stock motor, a few minor upgrades and yes it has a fuel system (or it wouldn't run!!! jk, yes upgraded one plum)
- This is pushing 9lbs of boost (motor was built on 9.5:1 ratio so i know i could push 14/15lbs...just not right now)

Thanks gents!

If this is 9 psi then that dyno is about 60-70 hp on the hi side, unless you have very well ported heads and other mods to increase the flow from factory considerably.

703rwhp is roughly 780 crank hp on a viper these things are right around 11-13% drive train loss.

Judging by your torque numbers this motor is far from minor mods, or the dyno is far from truth. Typical paxton cars on stock or near stock motors make less torque than hp, the numbers reverse when the motor gets significant flow upgrades.

lol depends on your definition of minor sir. Ill tell ya, everything was upgraded but the heads and cam

More info on the build? Great numbers for just paxton with fuel system...

 

[plumcrazy]

is that max power at ~4200 rpms ?

i must be seeing this wrong. the power curve doesnt seem to jive with the psi/afr chart. or is it me ?

 

[Russ M]

Your looking at the torque curve, but after looking at the other chart I understand whats going on.

The a/f is good its on the right, the left side is the psi and this car is making at least 13 so that explains the hp.

Mileage also impacts the numbers, as the car ages, the driveline losses actually go up. 12% is a good number, but, it could be a bit higher on a high mileage car. The number also has to be based on direct coupling or 4th gear in a T56.
