Angus Fuel stepped away from making Nitro back in 2006. Fuel teams use Chinese made Nitro, it has a higher purity than domestic but I’m going back almost two decades when Don Schumacher racing was the only guy getting the Offshore Nitro. That’s one of the reasons Tony was unstoppable back then.
Nitro is brutal on elastomers. The exhaust is highly acidic so I’m unsure how the wide band 02’s and OEM ECU function unless the mix percentage is extremely low.
GT350 manifold all day everyday on the Gen2 with PMAS but the GT350 open CAI works well being you already have that. The bigger TB is no problem to tune for Wengerd Perf.
The 18 manifold inlet diameter is a restriction when moving into the larger TB’s
More power and with the GT350 manifold a flat power peak well past 8K rpm’s so no power loss on long shifts.
I’m a fan of the GT350 manifold on the 15-17 Gen2’s.
Small block V8’s as in 2 valve or 4 valve ? There is a huge difference but as you stated you’re not looking to debate. The first header bend radius off the flange is the most critical.
1.75” diameter get the job done on the 4 valve VCT Coyote.
Good choice on headers. Kooks does an outstanding...
Do a compression test.
Take some time and get the car off the ground and roll the wheels by hand checking for resistance. Check the driveshaft and axle shafts for play and any binding. The 2015-17 axle shafts joints are known to bind and pop, my needed replacement at 45,000 miles.
Alignment you...
How many miles are on the car ?
Have you performed a compression test ?
Are all the wheel hub and bearings in perfect condition ?
Have you had the alignment verified ?
Have you checked to make sure a brake caliper isn’t hanging up causing some added drag ?
What Air Box are you using ?
I’m with...
