[redfire03 svt]

The basic run down of my cobra is the following:

VMP blower at 18lbs with supporting mods
built 4r70w stalled auto with manual VB
Built solid live axle with spool

These numbers are with the converter unlocked and on 93 pump.

great looking car. when you bringing it to the track?

In the spring, still working on a couple things with the suspension.

Congratulations! It should run very well. Love the 4R in mine.

Congrats! I live in ATL. How far is Kurgan from middle Atlanta? Which track do you visit? I'm new to the area, so I'm still learning.

 

[redfire03 svt]

How much HP were you making with your 4R, and what times did it run?

Why no e-85 when you ran it on the mb?

 

[redfire03 svt]

E85 in the E55 was a nightmare, I first plan to run the cobra as it sits to see where I land.

How's it feel with the auto? My cars runs better and has better throttle response with e85.

Nice numbers

Nice numbers, what are you hoping for at the track?

Before the Kurgan tune it went 10.4 on a 1.48 60 ft. The suspension is fully adjustable so I feel the 60ft has a lot left in it. That plus the extra HP should put it deep 10s.

Big fan of Bob. He tuned my last build and will tune my next. Very nice numbers and very nice car!

10.4 is solid. What are the specs on the stall? I need one badly, because my 1.6s aren't cuttin it!

I have never had it on the dyno. I've tested from 7-25psi on my car. At 19psi it ran 9.77@142mph. I am certain it makes north of 700hp.

My combo is a full auto valvebody controlled by a 2004 Mustang GT PCM. Third gear is only held by the direct clutches, not direct and reverse clutches like the Lentech and Freddy Brown valvebodys. The manual valvebody is a stronger choice for the 4R with that in mind. The full auto stuff needs to have precise EPC in order to live at higher power levels, in part.
