Just got back tonight from Efi Alchemy's new shop in north FL(really nice place). First pull was with one cutout open and the other close with 29* of timing. The other pull was with 28* and both cutouts open. I wanted to see what it would have put down with 29* and both cutouts open but it was getting late into the night.



Tonights graph:


This graph is one that i pulled a month or two back at a different shop, but the tunners of the shops say their dynos put out almost the exact same numbers. Seem to have lost some power somewhere?

judging by the pictures the old graph has an STD correction factor whereas the new ones have an SAE correction factor. that will make up some of the difference. STD cf dynos higher than SAE. the ~13 rwhp difference is probably negligible if both dynos were in SAE correction or STD correction. do you have access to the actual dyno files? if so you can use winpep7 to view them and make the change yourself.

Nice truck! What will it do in the 1/4?

That second standard-corrected curve is very impressive! You've got 260 ft-lbs from 2800 through 6700, with a peak of 320! Not hard to calculate, since the curves must cross at 5252 rpm, which is at 105 in this case.
Thanks for sharing!

yea i think ive seen ya on there a time or two junkie06, and thanks for the comments fellas..i will see this weekend what she will do at the southern truck shootout..hoping to see 12.4 or better on motor

and im about to do a compression check and and throw in some tr55s..what should i gap them at with my setup?

I keep returning to this, and I found myself running the numbers.
The curves must always cross at 5252 rpm, and in this case, that's 107 mph. Not 105 like I rounded off to last time.
This combo has, assuming it was a typo, since I can't find those tires in that size, 275/40R18 rear tires, so that's 26.57" new, unmounted.
With 3.42:1 gearing, 107 mph should be 4623 rpm at 107 mph. So this converter is slipping 630 rpm.
From my own testing on my own cars and trucks, I've found that a good converter that slips 400 rpm just above stall will still slip 400 rpm at redline. Same story if it slips 1200 because it's hatefully loose.
So, the torque curve comes up at 48 mph. Running the math, that's a hair under 2700 rpm, not 2500 like I rough-figured last time. But 2700 still impresses me.
And it hangs on to 134 mph, which is really a hair over 6400 rpm. Still impresses me.
Any idea what intake centerline the cam was installed at?

im not a 100% on the centerline..it was early into the next morning when it was set and i was exausted without a memory..i ended up getting the time slip i wanted..12.3@109..the 60ft was 1.79(needs improvement)..looking to see 11.9 with a little weight reduction and gears(cam only, no spray)

here's a few pics from the shootout:

and a little something i brought home

I'll just e-mail TR.
Those Hoosiers look mean! I bet they'd love a 4.10:1 gear.

L$X$10

iTrader: (4)

yea they would!..for track anyway..i drive the truck daily and love the 27mpg it gets on the highway with the 3.42s..i think ill be throwing in the 3.73s for the best of both worlds

Awesome results I hope you get your 11sec slip soon! With a 125 shot of gas you might see 10's after the gears and weight reduction!

I've always thought the LM7 & S10 were a perfect fit. Both can be had for cheap, and S10s love LSX power!

Very nice, and the mph backs up the dyno numbers!
