peak hp at 2750 thats weird? Congrats non the less though

look at the curve its almost dead flat , on my street testing it pulls hard to 3700 in fact it looks to be rising again at 3000 i let out of the runs early. i was interested on some thoughts on the curves i havent seen any that flat seems like a good thing if you went off of average horse power and torque through a whole gear . though that flat torque curve could be hard on parts ?

i cant the boost hits 60 psi :eek: i need to keep the fuel down to keep boost down the tune i ran on the dyno hits 50 psi on the street with the top turbo gated as early as i can have it without modifacation .

to be honest i dont think i will need anymore out of it. it feels stronger then the dyno show's , my tune i dynoed last ran a 12.72 @ 108.5mph on a 1.84 60, ran less power on that dyno than this tune and didn't have neer the problem with the tires slipping on the rollers. but only the track will show . it is a true testimate to this kit 400 less pw ( currently @ 2800 usec) and more hp

While most people think Trents numbers are low this was done on a Mustang 250 dyno that has a hard time keeping traction when you get in the 500hp range. For example: I dynoed my '02 Cummins on a Dynojet here in Meridian, ID at 648hp uncorrected (700hp corrected) and drove to the 2002 Edge Days the next day to dyno on their Mustang 250. I did 560hp with no changes. Maddog was doing in the low 700's with his Fummins on a Dynojet and did 580hp. He got first and I got second for hp.

thanks guys , the real # i can figure with taking my mph from my 1/4 mile runs is around 615 , trapped out at 112.7-8 mph those are excatly what i was hoping for potential for a high 11 . i can only figure that if i throw the rest of the fuel i have at it, it should easily do 630-640 , i have another 450 usec at my disposal till rail pressure drops below 21k.

Are you still running at high altitude with those times and mph??? If so thats impresive and you need to make a road trip to some good air!!

nope that was in pheonix pretty low, i am curious about the altitude thing now . i dont know how much of effect it will have now , before the twins it would have probably been alot for i had alot of unburned fuel i needed air in a bad way , now i have zero unburned fuel these two turbos can provide alot of air. i will know soon our track opens april 17th . it will be curious to see .
