Paxton dyno numbers.

[Juiced 66]

Finally had the car tuned with the novi 2200 and the id1000 injectors, jlt big air intake and boost a pump. Car made 759/593 on pump gas at 6,950 rmp. I didn't spin it any higher just to be safe. Timing was around 13* and air fuel was rich just under 12.0. Drivability is good, I just need to have it tweaked a little to smooth out a couple of things. I don't beat on the car very much, so hopefully it won't break on me. I'm planning on a rods/pistons swap after the first of the year.

759whp on pump gas? What boost level? What dyno?

Very Impressive!

Wow!

Boost was 13 psi. It was on a dyno dynamics dyno, or maybe it was a dynocom, I can't remember. It wasn't a mustang or a dynojet.. I know that for sure.

 

[ArtVandalay16]

Wow, probably accurate being your at 13#. I'm assuming one size smaller pulley, which is 3.43?

 

[slamdcoop0428]

Awesome numbers but I wouldn't say you car is running rich. 11.9-12.0 is pushing it. My car is tune around 11.3-11.5 just in case for a not so good tank of gas or weather change.

 

[Need4Speed03]

Very impressive numbers! I agree though I would fatten it up some, 11.5 to be safe. Close to 12.0 on a FI car is actually alittle lean.

 

[Juiced 66]

It has the 3.30 pulley on it right now. Also, I always thought that 12.0 was pretty much a perfect a/f ratio for a street car. I will be mixing fuel in it as I did when it had nitrous on it. It's not a daily driver so I could run fuel pretty much all the time if I wanted.

I'd like more input on a/f on these cars. I want to be as safe as possible with the blower on it. I honestly wouldn't mind backing it down just a little. If a little more fuel would be better than I'll richen it up some. All input is much appreciated.

Nice. Vids or it never happened.....

 

[REPCobra10]

That's very impressive, OP! The numbers speak for them self...:beer:

 

[SILV03MustangGT]

Nice numbers but that's a little lean for a blown car. Was that afr reading off a sniffer or the widebands?

 

[Juiced 66]

I have a vid of it on the dyno on my phone. I'll try and post it from work this week once I put it on my computer.

 

[Juiced 66]

That was the reading from the car.

It was running around 11.6 or 11.7 I'd say from about 3500 till 5,000 or so and then began to creep up till around 12. I'll be at the shop again this week for him to tweak on it to help with drivability. I'll get a good pic of the a/f and post it. I may have him add just a little fuel to ease my mind. I'll check it really close. LOL

You have a built engine?

from the famous tapatalk.

 

[Juiced 66]

No built engine. I'm going to add rods and pistons sometime after the first of the year.

** correction, the readings were from the sniffer, which my tuner said were reading a little leaner than my car was showing. He said I may have an exhaust leak that I can't hear which would cause it to read more lean. He even switched out the o2 sensors on the dyno and it still showed the same. Im going off the graph which was reading from the sniffer. So if my car was actually a little more rich maybe I'm fine. I'll double check everything his week just to be on the safe side.

I did pull my plugs this morning after 2nd through 4th pull and everything looked really good.. Although I'm no expert.

I would, my car sees according to the logs about .79-.80 lambda all the way to 7500 RPMs. 11.1-11.2 AFR using E10 stoich. with your car leaning out like that up top there is almost no margin for error.

 

[Juiced 66]

I appreciate all the input, I'm def going to take a second look at it. 25 hp isn't worth hurting my motor over.

 

[beefcake]

nice numbers

on these carsk, don't look at the sniffer, look at the lambda readings from the factory 02's

 

[RFM50]

Very nice numbers!!! I love my Paxton! I can't wait to build my block so I can up the boost!
