My X-Charger dyno'd at 267 rwhp/269 rwtq. I thought it was pretty weak.

I have the HO-PO Kit with 2.8" pulley.

Does this sound normal to you guys? What are the other X's getting?

Note: My Mods are in my sig.

I'm hoping with 3.73 gears and my Spydershaft one-piece, I'll hopefully be kicking near 300 rwhp/300 rwtq.

In your other post didn't you say you have a custom dyno tune? If so that is low; if that's the tune that came with it that's about right, Doug's mailorder tunes are pretty conservative (very safe) What was your afr? Probably pretty rich. Mine is a manual and with a custom tune got 287hp and 301 torque.

Your not going to get 300 by installing a gears and a driveshaft. Just curious, are you running and X or H pipe?
Can you post your dyno sheet?

For the Bama tune that is pretty much right. Before my custom tune mine dynoed at 26ish and now it is at 271. Don't read too much into dyno #'s, as nearly every dyno is calibrated just a little different. Was it a Mustang dyno, because if so those always calculate a lower number than a dynojet. Need more info man.

In the other post, I was running it on Doug's tune.

I use true dual H-pipe with a pair of older flowmasters. Don't have a dynosheet.

It was a mustang dyno.

Maybe I should get it dyno'd at Steeda instead of BBR. Since they have more experience with the X-Charger? Or should it not matter?

the mustang dyno will make a difference. supposedly it shows numbers thatare double digits less than a dynojet dyno.

I think the Mustang dyno reads significantly lower. I would bet your dynojet numbers are closer to 300 rwhp.
