I just got a Paxton 1200 installed and dyno tuned on a dynojet.

379 rwhp
354 rwtq

I lost about 10 hp due to the 20x10's I'm running out back. Only other performance mods are KB boost-a-pump and MAC axleback.

The stock predator tune was almost on the mark, just had to make a few fuel/air adjustments. I'll scan the printout asap.

Guessing the purple a/f is the final one? Looks pretty good.

How much boost?

Pics?

Not bad numbers out of the 1200 kit. I looked into that and decided I am going to want more and go for it, when money arises for brakes and internals first.

congrats!

I would think though that you could probably squeeze alittle more power out of it if you wanted to. How much boost is the kit creating?

nickvaz

8 lbs of boost

Thanks bro. The first run was on the preset Predator tune which pumped out 369.32 rwhp. My installer made a few adjustments with the fuel/air and the next run was at 379.82 rwhp. I went with a conservative tune. The tech said he could of squeezed out another 10-15 rwhp. I'm happy with the numbers for now. I'm pushing 450 hp to the crankshaft!!

Did you dyno with those big whees/tires on? If so, that brought your power down a bunch. On my Vortech kit, I dyno'ed 439 with the factory 17" tires- but with my 18" DD bullitts, I dynoed 420. Just FYI, that's all.

nickvaz

Yeah, I dynoed with the 20's on. I could probably see another 10+ rwhp with the tune I have if I put on the 17's. The power's there if I want it.

Is the a/f running a little bit too rich?

Lowe!

Interesting. I bet you have more in there somewhere. That looks like a nice power adder, leaving the intercooler and plumbing behind. Nice option! Like a super CAI.

Also interesting, I dyno'd yesterday in less than optimal power making conditions, after completion of the LTs (see sig for all mods). I'm up to 330 rwtq now, only 24 #/ft less than a supercharger!

Of course I could only muster 311 rwhp.

nickvaz

It was on the base tune. I had to limp the car around for a couple of days until it was dynoed. Between 1-2.5k rpms it'll be a little rich, but it levels out once you get into boost.

tom281

The reason I commented about additional power is because my Vortech system is not 'cooled, and it also is rated at 8 psi. With this system and FRPP delete plates & offroad H pipe, it made 439 with the 17" tires, and about 420 with the 18".

Your 20" tires are probably costing you closer to 25-30 horse on the dyno, but none-the-less I would think that there is more power to be found. Now on the otherhand, if you want to stay ULTRA conservative, then you could leave the tune where it is. Eitherway, you've got a supercharged Mustang so again, I say congrats!

nickvaz

Ur numbers at the wheels? The delete plates and O/R H are probably giving you an extra 20hp?

tom281

Yep, at the wheels. Checkout www.brenspeed.com my car is the car running their Vortech package. I would think the delete plates and O/R H are worth a solid 20 hp on a supercharged engine. Anyway I'm not trying to rain on your parade or anything at all, so I hope you don't take it that way. You've got an awesome car and should be proud!

nickvaz

I don't think that at all bro. Does the shaker system add any power, and does run a different manifold?

tom281

Nope, my shaker isn't even hooked up, and even it it was it wouldn't help on the dyno at all.
