well I just got back from MTI

Dyno Jet Model Number 248C Dynometer



very happy with the results.

First run

91.4*F 30.17-0.90 in.Hg 0ft CF=1.01 Rpm/Mph = 78

Max torque = 253.4

Max Power = 257.8

2nd pull was

91.5*F 30.17-0.90 in.Hg 0ft CF=1.01 Rpm/Mph = 78

Max torque = 252.7

Max Power = 258.2

when I can I will copy the graph and post up.

 

Were these pulls in 3rd gear?

 

great!

does this mean all gear pull ,cf=1.01 =3rd gear

or did you do the second gear pull?

Good numbers, now go get that cam in

 

hey thanks Creed
2nd gear pull
78 mph was where the rev limiter hit.(6200RPMS)
I have video of it
but Imagestation is real crappy with the resolution, and it's hard for people to up load.

 

Can you refresh my memory as to what you have?

 

A 4.8L of course
as far as mods go,
just about every bolt in you can buy, except for NOS, a S/C, or a Turbo.
havn't even gone into the motor yet
a 2800 vig stall and 4L65E transmission, 3.73 gears and an Eatin posi

 

I forgot to ask,
I havn't run mine with the new stall yet on the dyno
Torque Thruster 3000 3.0str

Did you have any torque spikes? Prolly not running in 2nd gear.
I'm just not sure how its going to go with an all gear pull when I go back.

 

no torque spikes.
the only time it spiked was when they hit the rev limiter

 

Nice #'s Dan.

 

You know, a 6.0 with a small cam would add 100 hp and tq to those numbers. You need to hurry up.

Good results for a 4.8 BTW.
