on the drag strip 3hp is generally a mph so I'm going to guess around 9-10 hp.
____________
60ft-------1.42
1/8th------5.97
mph-------119

ok , I did not know that ,,,I guess now I have a number to shoot for. Previous dyno was 211 hp , so looking for 216-220 hp .

roy did you "recalibrate" the sensors or anything? or just install and go.

08 Busa, just a little longer and louder and lower than the 14

the secondary TPS doesn't really seem to matter. I have moved it to both extremes and the ecu never threw a code. there is a painted mark that was applied after the sensor was initially installed, and you can just line that back up.
on the primary tps, you can set it with a PCV. When you calibrate the tps it shows the tps voltage that it sees. You adjust the tps until the PCV shows the correct voltage. this may be better than just using a volt meter since the sensor ground is isolated.

Jim or Roy..............have you guys done any tests of the 48's............I'm wondering if they make any more power than the 47's?

I got to test the new throttle bodies at the track today.
I picked up 3mph and .15 seconds.
I will head over to the dyno shop and and see what the true increase in hp is.
Roy
3 mph and .15 from a 1mm increase in TB size? Do you have the slips to compare? I wonder if there aren't some other contributing factors?
How did the dyno testing work out? The bike was making 211 hp before, right?

I'm curious why everyone seems to be going with the 47's vs the 48's?

One potential reason is that bigger is not always better.
Another issue is that the 48's are very thin, and have only recently been developed.

Thin meaning that reliability could be compromised?

No...but harder to machine, closer tolerances.

No. No controlled back to back testing yet. There are different stacks etc. that we are going to be testing as well.
The 48's are very thin but I don't see any reliability issues. We gave a set to Rickey Gadson to test and once his MIROCK Real Street bike is at the track with our newest CNC cylinder head and cam package we will have some dyno numbers and track performance info to share.

Appreciate this inforamtion Wrongway....Mark is a super guy to deal with....he was able to bore my throttle bodies and mail them out within two days.
quote:
the same shop that is doing the boring on a CNC is making stainless blades. His prices are great and he can make anything ... but you need to strip down the throttle bodies and do the reassembly.

I am surprised to hear that ... he usually replies pretty quickly. You may want to try again , or I can forward your information to him . I am sending a few more sets out this week.

Ok I realize this may be a dumb question but here goes..........when you bore the TB's to 47 or 48 are you running flyless or are you putting 47mm or 48mm blades in?

there are 47 or 48 mm primary blades with no secondaries.

assembly of the throttle bodies are not as easy as you think. you have to line up the two halves before assembly. I had to make a jig for the alignment holes to square up the two halves. if the factory put the holes there for assembly you might think it matters. you have to balance the throttle blades left side to right and should adjust the air screws with vaccum and a gauge or on a running motor with 4 gauges. the throttle shafts have to be elongated for the blades to fit. the screws should be loctited and staked to make sure they dont come loose. a lot of you guys can handle it just be aware of what should be done so your dont have problems.

the 46 mm doesnt need the slots widened, 47 and 48 mm need to be hit with a small ( .060" ) file , but the material is easy to remove.
I did not need a jig or fixture to align the 2 halves. I assembled the primary shafts and blades for both halves , then bolt on the stepper motor ( need to instal the seconday shaft first) . after the secondary stepper motor is bolted on , you can slip the second set of throttle bodies on the secondary shaft and bolt the 2 throttle bodies together.
I have a home made setup for balancing the the throttle bodies , but you can only do 2 at a time ,, so i do the right side using the air bleeds, then the left side using the air bleeds. the i connect 1 on the right side and 1 on the left side and use the adjusting screw that connects the 2 primary shafts to balance the 2 halves .
