Elantra N CPI Testing Results

Let us note every modification from stock first.

HPFP Upgrade 

A0 Injector Upgrade 

Custom line from sending unit in gas tank to HPFP with tap for CPI

LR3 Coils with NGK 9 heat range plugs.

Milltek Sport Catback 

Our custom CPI kit.

While setting up, and testing a few things on the dyno, a coupler split. This caused us to be limited to 21psi. 

However we still made 356.91WHP on this car! Extremely high for a OEM DP car, OEM inlet and intake.

So what is next for our Test Elantra N?

HT400 Turbocharger

Downpipe 

And let's send it pump to 450whp!
