Interim dyno results - Mosselman MSL65-80 turbos - Initial runs with pump gas and E85
Ok yall.. the INITIAL results are in for the Mosselman turbo installed, with Cary Jordan tuning.
These turbos are EXTREMELY strong, smooth and have run flawlessly thus far and clearly have a ton of headroom left at this stage. - PLEASE READ FIRST - 1. Massive tire slip on every run, so torque is actually underrated a bit. Nothing we could really do about it at the time. Warmer tires on later runs helped but were still an issue throughout. Combination worn rollers and need different tires to hook that kind of power. 2. This was a 92oct pump gas run first on a nearly empty tank, then 5gal of E85, bringing it up to E65 registered in the tank 3. My stock HPFP absolutely falls off a CLIFF after about 6400rpm running E85 (I was reading E65 on the BM3 sensor) with every run. Cary did an amazing job working with that, but its clear the HPFP needs help to get really serious on E85, so we dialed the tune back for now. There is clearly significant head room with proper fuel support. 4. These are interim results for E85. Pump gas is dialed in essentially perfectly, but E85 requires more changes to accommodate the fuel, which is likely in the future with HPFP and EU5 injectors. 5. I included the best stock turbos, custom tune run for reference, so you can see the improvements. Custom S2 Mosselman turbos with pump/flex fuel tune from Cary Jordan, on a Dynojet at CarbConn in Kirkland WA 92 octane RWP averaged STD corrected - 588.12 92 octane Torque average STD corrected - 484.09* (serious tire slip throughout) E85 RWP averaged STD corrected - 632.35 E85 Torque average STD corrected - 573.78 (still some tire slip) So for comparison: 3/11/2021 - full stock OEM tune RWP averaged SAE corrected - 403 Torque average SAE corrected - 466.85 3/17/22 - E85 custom tune with new turbos E85 RWP averaged STD corrected - 632.35 E85 Torque average STD corrected - 573.78 Juuuuust a little difference..
