Dyno results Paxton 2200 stock pulley

[TTUhouston]

max from 3 runs is 538 rwhp, 432 rwtq.

The dyno had a big blip at 6700 RPMs to 7100 RPMs but the datalog shows .27deg (under 0 until this RPM) of knock and 13.5-15deg of timing at the same time. Doesnt look like it is knock. anyone seen this? Doesnt seem to buck like it looks on the graph in real life; pretty smooth at high RPMs.

Other than the bumpy high RPMs the numbers are about what I wanted to start with. I can always pulley down but right now I am happy with this power level.

Is the car running stock cats. Looks like it's choked at the top of your rpm band or your belt is slipping. A Paxton should keep making power all the way to redline.

Bone stock exhaust and everything but the supercharger, bap, intercooler and injectors. I also think it may be choking. I thought i had seen others with a smaller pulley run more hp through bone stock exhausts. No? I did not think about belt slip, good thoughts thanks.

530 hp is nothn to take lightly. Ive put cars in the woods with far less lol. yea get use to that power then pulley down.

thats the smart way to do it. I've bitten off more then I can chew on more then one occasion and their EXPENSIVE lessons to learn! smh

switch out the midpipe!

+1 on getting a off road mid pipe on there. I bet you pick up 30-40 hp from this mod alone.

Riddick, I wouldn't be surprised to see that as well. Let's getcha a lethal performance midpipe. Message me and we'll get it shipped ASAP.

My favorite thing about the car is how quiet it is, unsuspecting. My last car was straight longtubes stroked LS motor and my wife hated it. She still likes driving this one. Exhaust work has been off the list for a reason. Sorry Logan, may change my mind in the future?

570whp is around the max these cars can handle before upgrading the fuel system. I would imagine a Paxton should be able to get close to that without too much trouble. Perhaps the dyno is just reading low?

Would check for slippage too.

Hey buddy, no worries at all. Always here to help. Still pretty damn cool seeing an otherwise stock car put out these numbers. Enjoy the car!

You'd be surprised how quiet the lethal x-pipe with GT500 axlebacks ends up being....

 

[TTUhouston]

Gruca, now your speaking my langauge... Do you have issues passing inspection? My last car wasn't inspected for like 8 straight yrs and I ended up selling it for that reason. Do they make a high flow cat setup?

Off road x with gt500 muffs is quiet. You'll love it.

Stock pulley should be making a bit more power.

My 2014 car was Paxton at one time and it trapped 127 mph with the 3.8".

Car probably made a hair over or right at 600.

Yes! I still need to put the Lethal O/R H on my Coyote.
And OP if you keep the resonators intact it's not gonna be nearly as loud as that LS you had.

This is veeerryyy true!!! I just spent around $8k on my bottom pushing my stock bottom end. Definitely a very very expensive lesson!!!

The gt500 mufflers with a off road pipe are not loud at all. I'm running kooks longtubes with a off-road X, factory resonators, and gt500 mufflers. When you are cruising its whisper quiet, when you step on you can definitely hear it but it's perfect. You should look on YouTube for some videos, they are by far the most popular axle back for these cars

I moved just far enough south of Chicago to not have to do them. However, when I did have to do them, they just hooked up to my OBD port and checked for codes and for the o2s to be ready. A good tuner will make you pass that. Visual inspection isn’t a part of it, so I never had to worry.

 

[TTUhouston]

No codes thrown to mess with inspection? You guys are pretty convincing...

And my thought with the 3.8 pulley is that it would be pretty hard to blow the engine. I have also blown in engine with less and it is not fun. I can tell that I will be pulling down in the near future though.
