Wanted to see some dyno graphs of those with 6lb lower pulley's.

Was thinking about adding one and was curious what you guys thought.

Is it over revving too much?
Did u notice a big power increase?
I heard the peak #'s weren't all that substantial, was curious what the overall graphs looked like compared to the 4lb.

Oops, you said 6lb er's.

 

Hey Beef, sorry I cant help with the pullie issue but how do you like your Factory Tech valve body?

More to the point, how does it shift at part throttle and at WOT?
I want to get one but I dont want something that will snap my neck while Im driveing normally.

Thanks

Let me help ya here Andy...........I just took my truck down from 6 months of storage and took her for a ride. I put Greggs valve body on over the winter so these were my first impressions

It firms up the shifts alot. It does not snap your neck at any throttle position. All shift points are very frim. I can get sideways into second at WOT!!!! Remember I have no pulley or chip.

and I'm guessing not much tread on your tires.

 

Hey soap thanks man that helps a lot. So then, I assume the FT vb wouldnt be too aggressive for a dailey driver?

Actually they have 1000mi on them and still look brand new. Ask lightning Jeff he was there when I got my chrome wheels remounted.

Where did you get that hood? Cost? It's very nice!

 

how bout some 6lb's get in here

 

Sorry I dont have any Dyno Graphs (yet) but I can give you my input on JL's 6 lb pulley. I've had it on my truck around 1,200 miles now and not one problem just one word of advice if you havent done it already get new plugs if you are going to do this (preferably Denso Iridium Spark Plugs). Beside the very loud difference in blower pitch from my 3# to a 6# The power increase is a lot more from my 3#er or so it feels. With a G-Tech Pro with my old pulley ( Jl's 3#) I pulled off a 0-60 at 4.83 with okay traction and a 1/4 mile of 12.88 ( or so the g-tech said ). With the new 6lber i pulled off a 0-60 of 4.6 and a 1/4 of 12.32 I did a couple of runs with it but that was the best times i could get with it. Hope this somewhat gives you an idea in the power increase from a 4# to a 6#. I will upload my dyno graphs on March 3rd when I take it in.

I don't have a graph to post, but my sig has the peak numbers for my particular truck with both a #6 lower and #1.5 upper. later,

just want to say that my g-tech is very accurate . i tried it at mt local track and it was within a 100 th of a second of my actual time,every time. i also have a #2 upper and a #6 lower and it is amazing.

 

Krummer................................

Wow!..........the hood man......the hood.....Any info would be appreciated.
Too cool!
