Looks good Jim. Out of curiosity, are the rotors on the 3.8 longer or larger than the 3.0?

I dont have a 3.0 to compare but the 3.8 is about 2 inches taller with the upgraded intercooler packs so im guessing the rotors are quite a bit larger.

Guys running the 3.0 Whipple with billet motors make 1200 whp. The 3.8 makes 1400 whp. Thats right from my buddy who swapped his and picked up exactly 200 whp with it so the rotors are likely huge which imo means this is only good on the street with a larger CI motor with good heads otherwise the 3.0 seems much more effecient down low.

Turning the 3.8 vs. the 3.0 will certainly result in quite a bit more parasitic loss but it makes gobs of power so if one has the motor for it then I think its great or if someone simply wants to drag race its great to.

Looks good Jim. Out of curiosity, are the rotors on the 3.8 longer or larger than the 3.0?

Yeah lots of products do but why does whipple make the 3.0 for the coyote with o rings and not the 3.0/3.8 for the hellcats?

They also send cheap intake gaskets also. The 3.8 is built far nicer than the 3.8

Yep same ones rather use oe ones
Yep, I had a 4.5 I won’t go on about the nightmare I went through with it, stock gaskets with rtv still wouldn’t seal the warped manifold (2 of them). Had to get o ringed spacers

I will say the 3.8 looks like a quality unit, even the 3.0 was better planned than the 4.5. Still, they could have o ringed it

The 4.5 was crap cast aluminum cleaned up on a CNC. Are the 3.8’s made from billet? (Not the rotors, the case)

I will say whipple is not the best in customer service. You buy a throttle body spacer to fit their 112mm TB and it don’t fit have to buy a long 120mm that’s another 1300. I would have sold my 112mm if I knew that.
