RB dyno results

This is a dyno of new RBs. The regular old version that have been balanced to 0.2 grams throughout the RPM range. OEM tolerance is 1.5 grams, High performance tolerance is 0.5 grams. These should be able to take a big beating

These turbos also have the Thrust Upgrade.

This Mustang dyno supposedly reads very low and most are not happy. After the first pull the guy asked me is this right? I said what? He said the dyno it seems very high all pulls in 4th gear. 1st pull 475 535 2nd 472 531 3rd 474 532 the Cobb stg2 aggressive 351 395. I said I was hoping for 500 he then said this thing is a beast 470s on this thing is an animal. Temperature out was 78 and muggy so was hoping for better conditions.

475 535 was the highest run even though it is not on the sheet, he put my first ever Cobb stg 2 aggressive on there for comparison to now. Its impressive to say the least.

I will be at the track Thursday night to see what she can do the 1/4 in.

Ok to Terry first thank you for all your help this is a BMS flash that has some tweaks from Ken AKA Wedge, we had to get torque down to allow shifts from 4th to 5th and get fueling scale up for the map. Wedge thank you very much.

Congrats... Those are some SICK numbers. I did a few side by side DynoJet vs Mustang comps to see what I could find with regard to the % of difference, and if what I found is true, on a dynojet this car should make 555 / 625.. No wonder why you're have traction issues with DRs in 4th gear. LOL

Can't wait to see the numbers from the track. If the ET calculator is right and you can hook up, 11.1's at 121 is what you should run. But I'm not sure if that takes into consideration the monster torque you're putting down also. I'm thinking 10.9's with a 125 trap if the transmission doesn't take a dump launching the car in 2nd gear.

I will be happy with 11.1's but high 10's sound so much better. I could not have done this without your help Ken you the man I appreciate you putting up with all my texts and calls.

WOW!

And out of curiosity, with that kind of power, do you have any suspension mods on the car? Or are they along with your brakes stock?

I replaced my original 07 trans my build was 10/06 it was slipping badly when I was pushing it I did run 11.6's and a few 11.5's prior to her demise though, 3rd gear stopped holding during wot pulls.

I picked up a 2011 trans and put it in you can probably search my old posts about the swap

May I be rude and ask how much the swap cost? Parts + Labor.

Mine is def on the way out....Shifting out of 3rd is an awful feeling.

Edit: Great numbers on the RBs! Hopefully Rob's new balancing machine helps with longevity.

I got a used 2011 with 18k on it for like 1100 and a buddy put it in for like 800 a dinner or two and some monster drinks. He also put my RB's in my meth kit charge pipe and so on.

He does all my mods and work so if your near Columbia SC and need work Ole Boy can do anything needed.

I couldn't find any info within your transmission swap thread...so how was it? pretty straight forward? From what I've read, you really don't even need to code it, correct?

Any other info would be greatly appreciated!
