Blasting out if the hole lol for reference I've done a 1.6x 60',
(Left lane)



Got another half second off it...prob could've got another run in but was getting late got a few more things to do. With that mph it should be knocking on 10s

How are you liking Np149 in comparison to your original one? Does it hook up any better?

 

[randeez]

No input shaft, no np149...going to need longer driveshaft also, by like an inch.

No np149, input adapter didnt show up, and I'll need like an inch longer rear driveshaft.

 

[avalonandl]

[randeez]

Your hard work is paying off Randy, that's a great start! Let us know when we should all get together again and if you want to run her at Orlando Speedway or Moroso.

thanks james!
there is a few more things i need to do asap - aside from the tuning in general, on the logs from these runs upper rpm the injector duty cycle went over 100, soon as that happened im guessing they stuck opened and fuel pressure dropped. its set up for 58psi but i didnt have the boost reference connected. that may solve the issue short term but its going to be real close to 100%idc. i can probably bump up the fuel pressure to 65 or 70 and also boost reference the regulator - but again mostly just working with what i have, really need some bigger injectors.

i think after i fix the fuel itll be real close to trapping 130mph , issue with that is with the 4.10s im about to shift into OD which i was told not to do. also i need to get the shift lever and crap to shift into D3

Yeah, hitting overdrive would be ******* the transmission, we always held it to 3rd. With 4.10s @ 125 MPH you're motor's turning about 5400-5500 rpms. Up to 130 would be around 5700 mathematically. Is that what you're seeing?
