Thread: PLOG vs headers.

I've seen many dynos of stock vs headers.
10-15whp gains without a tune or pulley drop is the going rate.

BTW, primaries are measured by O.D.

And they gain almost nothing.
Sometimes nothing.

I've used a downpipe and plog setup on both of my Previous setups and seen little to no kr after tune and downpipe and plog. I'm in the minority that feels like headers and a plog downpipe have the same effect and produce the same results. I can only speak on my vehicles which were tuned by reptile.

None on hand. There was a tiny bit of gains in the mid range (negligible) around peak tq... but peak hp was never more than ~5hp more.
Headers on the other hand were 10-15whp across the entire curve.

May not gain peak but hp/tq under the curve im sure helps.........

Welcome to the rest of the car world where primaries are measured in OD.

Oh, should have went to the second page before posting.

Ah well.

Grimsin: how is the powerband with SDs? I found they had a better powerband than Pacesetters for a mild top swap. Smaller primaries FTW?

Yeah it basically comes down to whether you want to make more power or you don't.

I'm trying to accomplish 300whp. Vs cam tune smaller pulley stuff like that. Zzp says the PLOG can't handle more than 300hp

Also what work needs to be done to the SD headers to make them work probably. I know there is some things you need to do

I bought two 2 1/4" band clamps and two 3" band clamps.
Make sure your transmission dip stick isnt touching the headers and the a/c line.
Sometimes the crossover pipe can be a ***** to get installed.
Some people replace the flex pipe with a double walled flex, I never bothered.

Oh ya I had to do that also

So what should I go with pacesetter or SD. Idk what kind of work the pacesetter need
