120k ho sb, approx boost starts 1psi @ 3300 4-5psi @ 5500
Mustang dyno. My guess 280hp
I think decipha guessed 290
I would be pissed if I only made 280 with an aluminum headed, blown 5.0. Why only five pounds?
Its a old paxton ball bearing drive model which was designed in the 50,s. Its just my daily street beater and its perfect for that. your thinking of the novi 2000 that is a beast:evilgrin: if you really want powah turbo is where its at:evilgrin::evilgrin::evilgrin:
I was actually assuming it was a smaller blower from Paxton. I don't know anything about the older Paxtons so maybe it's not capable of moving much more air than that.
320 hp
Peak was over 300hp @5500. Torque was 330ft/lbs.
The results were better than I thought.
Maybe that will put her in the high 12's.
Nice!
300+ whp should get you 12s :).
Lol, w/tires spinning????:burnout::burnout:
Here is the dyno sheet and a video. I should have gotten out of it alot sooner. :punchballs:

That's a goofy plot. It doesn't show rpm to HP or torque, really. What I read is about 325 hp and 350 tq in the 4th gear pull. Is that all they gave you?
That vid is music.
I must admit, I popped a chubby while I was watching it ...
That graph is weird. It looks like about 320hp and 340ft./lbs. with 6psi but it's really hard to read the way it is. Was the pull in 3rd or 4th? Afr looks good, what's your timing like?
It was run through the gears. There was no way to lock the aod in 3rd. It would have been nice to see how the torque ramped up but when she shifted 3rd the rpms were already up. You can barely see torque go up after that shift. Peak?
Timing is around 31 and the iat's are high from the intake manifold. It will be moved to the discharge tube and should be more accurate.
The log could be read with eec buttstuffyzer but it wont let me post a .csv file
Sorry, when I said fourth I was thinking manual. My mistake.
Your fuel looks good throughout, like jridenour31 said. Nice, safe tune there. Sounds mean for sure.
Lol I guess I should have read your sig. It looked like you made the pull in 3rd but I was also assuming you were using a manual tranny. Are you running 31 degrees on boost or pulling from there as MAP rises?
What do I win for a prize for hitting right on the head!
No problem it's all good except it could be my mistake for not going with a manual. :rollin: but a 4r70w would work. Tune the transmission in the cbaza and dial she in.
I can't take any credit for the tune. decipha dialed it in close to make the powah.
Your turbo car will be plenty mean with tons of powah that's a given. Awesome build btw.

Made the pull in 1st and 2nd, those 1st 2 big spikes and the resulting data should be ignored till 2nd was brought up to 6200 hit 3rd dropped to 4300. It should be somewhat accurate from that point. 275-280hp at the begining of the 3rd gear pull around 4300rpm. It was probably detonating some and maybe why it starts to break up and flatten out before it falls off the cliff. The most difficult part for me is trying to locate the rpm for the given power at those points.
Timing spiked to 34 degrees with 196F iat's at 6200rpm with 6.5# boost. We never saw high boost on the street maybe the dyno was unloaded.
The upcoming tune will have a negative multiplier for spark adder vs act and hopefully puts her at 31 degrees with 5# boost. 11.8 afr. I don't know much of what he changed in the tune
Mike
Henceforth you shall have the title of oracle or the wizard lol
On 2nd though maybe you should stick with Mike, that's a good name. Easy for me to remember :rollin:
What ride are you rollin with?
I'm not a 5.0 guy (yet) but that sounds like a lot of timing. I thought closer to 19 under boost was a better idea?
That's cool, I was pretty sure the pull was in third. I'd definitely be addressing that timing issue. That's a lot of timing for a FI motor, especially for a pump gas car with no intercooler or meth.
I agree. Pulling between 1 and 2 degrees per pound of boost is pretty standard. I'm assuming you're on 91 or 93 pump gas and have no intercooler or meth based on your iat's. If you're not already detonating it's probably really close.
Just wondering but are you running the 215/70/14 tires on the stock 8 holes at the strip? I have traction problems with the 225/55/16 tires I'm running. I can only imagine trying to put 300+ ft/lbs to the ground with the 14" tires....
My tuner feels 31 degrees is ok with only 5#'s similar to a high compression engine. :confused: He wasn't there at the dyno pull but has tuned it on the street. Maybe he could come to the track and see what she likes :dunno:
lol I try to bring 275/40r17 mt dr's to the track, but have only cut like a 1.92 60'
You really have to pedal those 8 holes to have them do much of anything. :burnout: The dr's helps but can't remember how they hooked. One time I thought it spun and the next dead hooked and bogged. Hopefully I'll become a better driver because it looks like the power is there.
At least you're running drag radials. I'm surprised the 7.5 is holding up. I'm afraid that I'd break mine with drag radials so I haven't bother to pick some up and run 'em.
A lame stock 88 Cougar 5.0 with the steering rack leaking so bad it is a embarrasment to be seen. LOL
I got plans for the car though.
Ditch the spider gears by going full locker and get a set of GOOD axles.....problem solved.
No dyno graph should plot a gearshift.....JMO.
x2
I wish the graph would have shown how the torque came up instead of starting at or close to peak. Is there a way to lock the aod in 3rd for maybe next time?
Just visted the track and the numbers are close to expected. 13.3 @ 104 1.9x 60' 3680lbs Guess the heads were good for 30hp and the cam 15. Might be able to post some vid stuff up this weekend. mini dvdrw headaches and terrible driving included. :mullet:
