Will have to look into this. One thing I've been unhappy with is the shift points and response on my tune from local speed shop.

Probably just some piston slap on cold start up. As soon the pistons warm up and seat into the liner and it goes away. Common on modern V8's.

Balancer has to come off. Whole front of the engine will have to be torn down and radiator removed. I would not call it a hard job, but it will take lots of time. The oil pump rides on the crank shaft behind the front cover and balancer. I have looked into 8 rib option as well. ATI does make an...

He could not give me a firm price, but it would be closer to $1k for a one-off run of a set. He did say if I could get a group buy together the price would drop exponential. I tried to get a group buy together last year, because I knew this was going to start popping up. This oil pump design is...

Yep, I'm running the 3.375 pulley at 10psi and tuner keeps telling me anymore and expensive stuff is going to start breaking. 500rwhp at 5,900 rpm through 100% stock exhaust Anything over 10psi or 500rwhp and the cast pistons and rods are a ticking time bomb The oil pump failing is a common...

Good motor, but not the torque monster that the 6.2 is and is needed in a 6,000lbs truck.

When you go power sliding around corners on dry pavement you will understand. A 1/4 mile drag race is the worse example of how the blower changes the feel of the truck. It's pretty kick ass when the back end comes sliding out like you're on the dirt but still on pavement. I cant wait to get...

You need to add Deaver +2 springs to your list. Almost a must have with the Whipple or your wheel hop will be horrible.

Little tough to sell half a product when everyone needs the whole thing to install it..... just say'n

I find it hard to blame Torq too much for not being able to get your truck's tune running. Many people have had problems with the latest generation Ford ECU's, not only in the Raptor but in the 5.0 Mustang and new 2013 GT-500's as well. If they could not handle the tune, then they should have...

Truck hauls ass.

looks good. driver faster !

Not that much. General rule of thumb is 20hp per 1psi of boost on most modern high efficiency engines. 10psi would add 200hp. So that works out about right for 600-625fwhp and the real world dyno result we are seeing. With LT's and full exhaust it probably would be pushing more like...

The difference is negligible. Dyno numbers are never 100% accurate anyway. Remember its just a tuning tool. The engines make +/- 600 crank hp at 10psi.

Yep, propane is a biproduct of gasoline production, not really saving anything there. It does burn cleaner. CNG is the way to go but has a low BTU and requires a large tank. But if you buy a home compressor (not cheap at $10k and has to be rebuilt) you can fuel your car from the NatGas feed...
