How much does a Paxton Gen III benefit from headers?

[vbzatty]

My car has the following mods:

Paxton
Roe TB
Roe twin in tank pumps
Roe injectors
Roe crank pin kit
Roe tune
3" Mopar race exhaust
Upgraded IC
Water tank in trunk for IC cooling
Water injection (will switch to **** at my next tune)

At this point the car runs incredible but you can never have too much power. The headers are still stock but seem to be a good design and didn't seem to really be a restriction. Does anyone know what sort of gain I could expect with my mods?

my guess, 10-15 rwhp?

Not only do you get additional power, but you get a wonderful angry sound as the revs come up. Throttle response becomes more instant, and the whole power delivery becomes more eager.

So while there may not be a huge peak gain the power comes on quicker. Larger primaries I assume on the headers?

We gained roughly 35 HP on an 04 Mamba from stock exhaust. Did the swap right on the dyno.
Already had the Paxton setup on it.

No experience with it on this car, but on past cars (non-viper), headers can make pretty nice gains on FI cars. You're already forcing the "intake" side, so anything you can do to free up the exhaust side can only help.

SC cars get more gains than a NA car with just headers. should be around 35-40rwhp

The real question is: How much power can a Gen 3 cast motor sustain?

Looks like you may have the fuel...

Testing the limits? ?? IDK
