Hi people,
I tried searching for the -5 Vs -10 thread however I could not find it, this topic may be a little different as the car is running on e85.
Key considerations
- Motor is a fully built Rb 26 (26 bottom end)
- 262 in/ex cams
- Car is built for street/drag
- The car made 420 rwkws on 20 psi, we tried raising the boost however there was no power gain (I believe turbo’s were out of puff)
- Fuel system is more than capable of 500+ kws
My questions are
1. How much laggier would -10s be compared to -5s (running e85 can put more timing into it)
2. Is there an in-between turbo or any other turbo suggestions that will get me up to 500rwks?? (please keep in mind that this is a street car and needs to be low mounts)
Attached is my current dyno graph
Thanks
Daz
