Competition Can you do this on the dyno?

Not 500's thats for sure. My last unlocked pull was 404 and thats with my current setup

So does anybody have any ideas how I could nail out some more boost? If I get the opportunity Saturday I plan to make about 8 pulls back to back, 2 with injectors only, 2 with box on kill + injectors, 2 with Box + injectors + sticks EZ on jumper 3, 2 with Water Methanol + injectors + Box and the ez.



Maybe I am way off base but I am thinking that if I can pull up another 10 psi on the Dynojet there is probably another 40 hp lurking in that 10 psi that I could grab. What do you guys think?



Any ideas?

The Dyno-Jet is an inertia type dyno. The rollers you sit on weigh a combined total of 5400 lbs and there is no provision for loading them. It also has a barometric provision that automatically adjusts for altitude. As I understand it it is supposed to take the "human" factor out of the dyno runs and keep the numbers consistant for all Dyno-jets.

Dunno what is going wrong for you guys. We've never had a problem here. Are you sure the TCC is locked up? 200hp or 800hp, the boost is never that different like you are running into.

I dynoed same day as JRandol and had the same boost on the dyno (29 psi) as I do on the street.

Ok guys, maybe I am loosing my mind. I am running on a different Dynojet 248 Saturday, I will watch this closely and see what happens.

 

[jrandol]

Maybe I did loose my mind, I dont know. Anyway, I ran yesterday on another 248 in Fort Collins. Power was darn near identical, same setup I ran 518hp here where in Denver I ran 520, close enough for me. Forgot to write down boost numbers without adding in the new toy Water Methanol but with Water Methanol I built 35. 4 psi. Consensus has been that this adds about 3-4 #'s of boost so I am wondering if I was building 32 before in Denver. Without Water Methanol I can build 42-43 psi on the street. That would make more sense. Anyway, new top # for me is 555hp (no torque readings :{ we couldnt get the sensor to stay on. ) Lots of tuning left with the Water Methanol so I think theres more left in the ole dodge! Oo.

Oo. Cool. Nice numbers. Keep up the work. You are doin' things right!
