Ive been looking, but does not appear to be available yet. The metal valve covers recently became available for Gen1 3.5L ecoboost engines so hopefully Gen2 is close behind

Yes, our radiator fits all 13th gen F150's. While the nipples are there - they do not need to be utilized and there's no downside to keeping them passive, especially with a standalone trans cooler. Ignoring these nipples will not negatively effect engine cooling in any way. * @Wfo Thanks for...

stock or modified - I believe anything you can do to keep these trucks cool will help. Radiator and trans cooler are worthwhile and fairly easy to install. the BOV config is easy to change on our lower pipe. email [email protected] with exactly what you're wanting (a photo always helps) and...

twin EFR 6258 turbos, 19-20 psi boost, mid boost wastegate actuator. 510whp (mustang dyno) on 91 octane. intercooler/radiator/trans cooler/ mostly stock everything else. Tuned on SCT X4, planning to switch to HPT at the next go around. it's been a great truck for almost 70k miles no issues

All 2017+ 3.5L engines have a "Variable displacement Oil Pump". This uses an electrical signal from the PCM to reduce oil pump output at low rpm. The reduction in pumping losses improves fuel consumption a small amount. But in our experience, a traditional 3.5L Gen1 ecoboost oil pump with...

there is always going to be someone who says "shoulda bought a v8" or "i want the 6.2L back" . Any V6->V8 motor swap is invasive surgery, high labor and high cost. There are very few raptor owners willing to pay $50k for someone to tear up their truck, change strategy, delete turbocharging/DI...

I was talking to cam last weekend, he said winfield/goose would be tuning your truck? will be cool to see what Cobb can do.

you are welcome! But i forgot to mention fuel -- 2 comments there: -higher octane lowers peak cylinder pressure. 93 octane on the east coast is soo much better than the 90-91 octane on the west coast. and of course 94-100 octane is even better for reducing peak cyl pressure -E85 really...

Turbo lag depends on which turbo size is selected and how hard the tuner is willing to push LSPI (low speed pre ignition) 600 at the crank on stock block appears to be the universally accepted safe limit. But, this is not black and white - the limit is not so much "power output" limit as it is...

i have some stock motor EFR dyno charts in the 500-600hp range. but i would not feel comfortable pushing the stock rods and pistons above 700hp (maybe on E85?)

the EFR twin turbo kits continue to perform. here is a Raptor dyno chart from today - 4.2L RMB stroker with our EFR turbo kit. The dyno chart does not do this vehicle justice whatsoever. We've made a ton of progress on the engineering side of the G-series stockish location turbo kit.. until...

We recently had a truck make 750hp at 20psi, on a 4.2L stroker from RMB. That is a lot of power, and definitely more than I am comfortable to push at the limit. As a result I'm leaning toward the G25-550 as being the ideal setup. For built motor and guys that want to go ridiculously fast then...

hey WFO, a few tips that may help: -When bleeding coolant, you'll want to keep the radiator cap tightened, but the degas tank's cap off. -the best way to do this job is first apply vacuum to the cooling system. most people do not have or want to buy this tool and it is not mandatory. -full...

the primary purpose is to add a mechanical BOV, or boost gauge port. the secondary purpose is a slight increase in intake manifold plenum volume

yeah !! looking good :) free shipping code on our site: shipfree transcoolers are 50% off with the radiator purchase i hope that helps
