[Hoist!]

Forgot the cranking pressure was 175 indicating a relatively low compression build as I requested to avoid to much heat down here in the florida sunshine.  I really could not be happier with the project.  John Sachs did a great job cleaning up the heads and putting the build together using my original pistons.  Everyone have fun and ride safe.  JP

Damn fine numbers, and curves! Is that thing still a 103?

Hoist!

Here is the final dyno from my recent build by John Sachs.  He put on Wild Things Heads, T46 g WT cam, 57 mm Throttle body and the Hi five A/C.  I had D&D fat cats and Mike Roland came down and gave a dyno workshop using my bike to demo the SERT.  I got a real education on the SERT and Mike convinced me that it really is the device of choice to tune these bikes.  Rides like a bandit now and lopes along at 80 at essentially no throttle so maybe I will get some milage out of it as well? 

Hey Pappy2.......sounds great!  Let us know when you break it in what kind of mileage you are getting.  thanks.  spyder

I got a response from one of our members that the TQ would have been higher if the throttle body was a bit smaller IE 54 mm or 50 mm.  John Sachs wanted me to post that concept here because he and Mike Roland feel stongly that the larger throttle body will not have a negative effect on anything.  It is still a 103 build and runs like a banshee.
I will post the MPG when I get some highway miles on it.  Right now the throttle is spending some quality wide open time as you can understand.  I see a rear tire in my near future even though the current one only has about 1k miles on it.

Never too big.
Realize that a throttle body DOESN'T rely on velocity to draw fuel out of a float bowl like a carb does.
The MoCo offers a 58 mm.TB in '08.I wouldn't hesitate to use it on any of my 103" builds.
MORE TORQUE ------------ I could have put more compression in Pappy's motor.Don't forget,he has a MILD BUILD !
Also the dyno pull is in 4th gear SAE.Add roughly 7 hp. and 7 ft.lbs. for 5th gear STD.

Thanks guys for that. I found that when Wes designed my 110 top end, he selected a 58mm for it. We Dyno'd it and TQ started low, and had to climb to 3 grand. This is with Perf 2:1 Fatcats. We had him send us the 62mm for testing. The bottom end picked right up. We gained virtually nothing up on top. But a really great flat TQ curve now, starting at 100 ft-lbs at 2 grand, peaks at 126, and never drops below 100! The 62mm stayed on the bike!

Hoist!

And it apparently made a believer out of Wes also, because his recommendation to me for a very similiar build was to use the HPI 62mm...which I did!

Can't wait to get it to the dyno for tuning!  Darn northern winter!

Scott, how does it run with my map?

Howie,

  Well, seeing that my bike hasn't left my lift yet, so far so good!!   

  It is on the lift with a cover on it until the weather breaks.  But - it starts instantly, idles well - very smooth at about 1k - (obviously is rich) - and it is currently running with my Rinehart True Duals vs. the D & D your bike was dyno'd with... 

  So, it runs fine for my current purposes.  Better rich then lean at this point.  Before I go for a tune, I will swap out the Rineharts with D & D's.

Pappy it looks like you got yourself a good build and a good looking dyno sheet.

I did want to go to a 54mm on my 113 build. Zippers thought different. I also have Red Shift 657 cams. They were supposed to be Red Shift 647's which Zippers also thought different. I have a D&D fat kat with the performance baffle. Zippers wanted me to install a Borzillia 2 into 1 but I did not. The numbers were still good as the bike has not been tuned as of yet. I did get the A/F ratio set but no timing changes as of yet. The bike did spin in 5th gear with a 6 speed trannie at 126 square. 

The reason Zippers kept the less agressive cam's and the smaller throttle body was for everyday driving. I would of liked to of have the more agressive build but I am very happy with the bike the way it is. It also is a very mild build for the street.

I would of liked to seen the numbers with a 54mm throttle body. If it would help my already good TQ curve.

Hey Dawg, was their thinking due to more engine longevity or better gas mileage?  spyder

[DCFIREMANN]

Spy I think it was both. Like I said I am happy with the build.

Wes indicated to me that properly tuned I should see around 35 mpg...which is fine in my world...

It is nice to see multiple people happy with their builds.  I really don't understand all the dynamics of motor building but I have great faith in John Sachs and Mike Roland, especially after they pull this kind of power out of a fairly mild 103 build.  DC, get your buddies at Zippers to put a big TB on the thing for grins and see what you get.  I also think the tuning thing is underrated now that I have seen the process and the results, I would get a race tuner and get that done ASAP.  If they will get the thundermax tuned for you then that might be just as good I just don't know who can do it outside their shop.  Peace, Love and Happiness to all.  Gotta go rip up some more tire compound.  Current temp 79 sunny here in SF.......

[pappy2]

OK MPG is around 35 similar to what I got before maybe a 1 or 2 better but not much.  Remember I had the zippers throttle body/ecm combo on there with the fat cats and it ran really good before too.  I really have a hard time not hitting it even a little when cruising the thing is a hoot to ride.  Have not been able to ride for almost a month now (little health bobble, not riding related) so the MPG is from my first real trip across the state 4 weeks ago.  Good luck to everybody as the riding season starts up north and be safe.  PLH  JP
