went back to the dyno today, After cam swap
 

well I went to a dyno GTG from the DTW site. They had invited me to join them over at Flat Rate Performance in Pearland.
still havnt got any tuning done for the cam :( havnt had time.
but I was well please with the numbers, on just a cam swap, and no tuning

old dyno numbers before the swap where
HP = 258.2
TQ = 253.4
this was at 91.4*F 30.17-0.90 in.Hg. 0ft. CF=1.01 rpm/mph = 78
new numbers, after the cam swap.... no tuning except for just to get it running.
HP = 268.3
TQ = 325.5 :eek2:
this was at 95.6*F 29.94-0.76 in.Hg. CF=1.02 rpm/mph 47.05

I also got the MPH recorded on the dyno.
max MPH was 148MPH

the Dyno was a DynoJet dynometer.

I am very happy with these numbers. and believe 13's are in reach on all motor
I will be making a trip to Allen in a few weeks to get it all worked out :D

That's hella torque for a 4.8. My 212/218 setup put 272/262 to the tires. Good job Daniel! :D

I forgot to add that this was an all gear pull.
I did a second pull from third gear and my HP numbers where the same, but the tq was a bit lower. but still higher than my HP, and my old tq numbers. :D

70ft lbs of torque. lol. holy crap! :D

Man. You really kicked it in the butt on the torque! Sweet!

Hey Daniel, Where is Flat Rate Performance? On 518, close to Broadway(Telephone)? I was over that way a few hours ago and saw a load of Rams running around and thought there might have been a meet going on. What all does Flat Rate Performance do? I have never heard of them.

it is off of Telephone rd. but closer to Beltway 8. about a mile off the beltway
They mainly specialize in Ford Performance. Cobras, mustangs, and Lightnings.
I have a friend that works over there, and has expressed interest in working on Gm tuning.. He tunes the Lightnings now. there where I think about 10 Ram trucks there, I was the only chevy there. and was the second highest in the HP. there was a Ram there that used to have a V^ in it and he droped in a 5.7L and turned out 282 Ponies. I do believe he is running on the gas tho.
I will be going back over to him to it Dynoed again, in a few months. hell maybe I could even get a dyno day set up for us. I would have to talk to him tho , and see how many of you guys, would be interested.
I would probably need about 10-15 trucks. there to be able to do it.

Can you post the dynograph? I"m interested.

:werd:
can u show before and after graphs.

Great torque results :cheers:
