well here are the sheets fro the mechanical fan removed power increase.
That 215 and 300 run was the middle and lowest of the second dyno day.

 

Nice they arent kidding when they say these trucks fall on there face about 4k rpm.

 

That's a product of the intake manifold design.

 

Do you think it's possible you had summer gas for the other dyno runs and winter gas for this latest run? I wonder if summer/winter gas even shows up on the dyno.

 

mine dosnt with my kegger mod and edlebrock filter when i hit 3k rpm im gone

 

Notice his best HP and Torque were when it was coldest.

 

yes that is like a dragster, heat slows things down. but this engine is designed to run a lifetime not 8 seconds.

btw. hughes FI air gap going in this week will add to this as I go. along with the air gap willl be 52mm throttle body done by________ over in wisconsin. and a summit/ pacesetter shortie headers. I am calling this upgraded manifolds air flow. once this is in I will send this all to hemifever for the tuner. will love to see the power and better fuel economy out of this pig.

I am drawing a blank on the guys name. I will look at the box it came in. Also very nicely done for only 140 bucks.

 

its this guy 1999blkdakrt. buying it off ebay? its actually 152.84 with shipping, but he refunds you 25.00 if you send him your old TB. im gonna be getting that one in the future, along with the airgap and 4,56's need more power for towing. my truck is gutless when towing, and it sucks!

 

Im still waiting on my stage 2 ported kegger to get to me. A freind pulled it off his rt when he did the m1 on a 408 got a smoking deal on it.
